Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf changes from Ingo Molnar:
"Lots of changes:
- (much) improved assembly annotation support in perf report, with
jump visualization, searching, navigation, visual output
improvements and more.
- kernel support for AMD IBS PMU hardware features. Notably 'perf
record -e cycles:p' and 'perf top -e cycles:p' should work without
skid now, like PEBS does on the Intel side, because it takes
advantage of IBS transparently.
- the libtracevents library: it is the first step towards unifying
tracing tooling and perf, and it also gives a tracing library for
external tools like powertop to rely on.
- infrastructure: various improvements and refactoring of the UI
modules and related code
- infrastructure: cleanup and simplification of the profiling
targets code (--uid, --pid, --tid, --cpu, --all-cpus, etc.)
- tons of robustness fixes all around
- various ftrace updates: speedups, cleanups, robustness
improvements.
- typing 'make' in tools/ will now give you a menu of projects to
build and a short help text to explain what each does.
- ... and lots of other changes I forgot to list.
The perf record make bzImage + perf report regression you reported
should be fixed."

+What: /dev/kmsg
+Date: Mai 2012
+KernelVersion: 3.5
+Contact: Kay Sievers <kay@vrfy.org>
+Description: The /dev/kmsg character device node provides userspace access
+ to the kernel's printk buffer.
+
+ Injecting messages:
+ Every write() to the opened device node places a log entry in
+ the kernel's printk buffer.
+
+ The logged line can be prefixed with a <N> syslog prefix, which
+ carries the syslog priority and facility. The single decimal
+ prefix number is composed of the 3 lowest bits being the syslog
+ priority and the higher bits the syslog facility number.
+
+ If no prefix is given, the priority number is the default kernel
+ log priority and the facility number is set to LOG_USER (1). It
+ is not possible to inject messages from userspace with the
+ facility number LOG_KERN (0), to make sure that the origin of
+ the messages can always be reliably determined.
+
+ Accessing the buffer:
+ Every read() from the opened device node receives one record
+ of the kernel's printk buffer.
+
+ The first read() directly following an open() always returns
+ first message in the buffer; there is no kernel-internal
+ persistent state; many readers can concurrently open the device
+ and read from it, without affecting other readers.
+
+ Every read() will receive the next available record. If no more
+ records are available read() will block, or if O_NONBLOCK is
+ used -EAGAIN returned.
+
+ Messages in the record ring buffer get overwritten as whole,
+ there are never partial messages received by read().
+
+ In case messages get overwritten in the circular buffer while
+ the device is kept open, the next read() will return -EPIPE,
+ and the seek position be updated to the next available record.
+ Subsequent reads() will return available records again.
+
+ Unlike the classic syslog() interface, the 64 bit record
+ sequence numbers allow to calculate the amount of lost
+ messages, in case the buffer gets overwritten. And they allow
+ to reconnect to the buffer and reconstruct the read position
+ if needed, without limiting the interface to a single reader.
+
+ The device supports seek with the following parameters:
+ SEEK_SET, 0
+ seek to the first entry in the buffer
+ SEEK_END, 0
+ seek after the last entry in the buffer
+ SEEK_DATA, 0
+ seek after the last record available at the time
+ the last SYSLOG_ACTION_CLEAR was issued.
+
+ The output format consists of a prefix carrying the syslog
+ prefix including priority and facility, the 64 bit message
+ sequence number and the monotonic timestamp in microseconds.
+ The values are separated by a ','. Future extensions might
+ add more comma separated values before the terminating ';'.
+ Unknown values should be gracefully ignored.
+
+ The human readable text string starts directly after the ';'
+ and is terminated by a '\n'. Untrusted values derived from
+ hardware or other facilities are printed, therefore
+ all non-printable characters in the log message are escaped
+ by "\x00" C-style hex encoding.
+
+ A line starting with ' ', is a continuation line, adding
+ key/value pairs to the log message, which provide the machine
+ readable context of the message, for reliable processing in
+ userspace.
+
+ Example:
+ 7,160,424069;pci_root PNP0A03:00: host bridge window [io 0x0000-0x0cf7] (ignored)
+ SUBSYSTEM=acpi
+ DEVICE=+acpi:PNP0A03:00
+ 6,339,5140900;NET: Registered protocol family 10
+ 30,340,5690716;udevd[80]: starting version 181
+
+ The DEVICE= key uniquely identifies devices the following way:
+ b12:8 - block dev_t
+ c127:3 - char dev_t
+ n8 - netdev ifindex
+ +sound:card0 - subsystem:devname

+Description:
+ Description of the scan element data storage within the buffer
+ and hence the form in which it is read from user-space.
+ Form is [be|le]:[s|u]bits/storagebits[>>shift].
+ be or le specifies big or little endian. s or u specifies if
+ signed (2's complement) or unsigned. bits is the number of bits
+ of data and storagebits is the space (after padding) that it
+ occupies in the buffer. shift if specified, is the shift that
+ needs to be applied prior to masking out unused bits. Some
+ devices put their data in the middle of the transferred elements
+ with additional information on both sides. Note that some
+ devices will have additional information in the unused bits
+ so to get a clean value, the bits value must be used to mask
+ the buffer output value appropriately. The storagebits value
+ also specifies the data alignment. So s48/64>>2 will be a
+ signed 48 bit integer stored in a 64 bit location aligned to
+ a a64 bit boundary. To obtain the clean value, shift right 2
+ and apply a mask to zero the top 16 bits of the result.
+ For other storage combinations this attribute will be extended
+ appropriately.

+ This allows accessing extcon specific variables.
+ The name of extcon object denoted as ... is the name given
+ with extcon_dev_register.
+
+ One extcon device denotes a single external connector
+ port. An external connector may have multiple cables
+ attached simultaneously. Many of docks, cradles, and
+ accessory cables have such capability. For example,
+ the 30-pin port of Nuri board (/arch/arm/mach-exynos)
+ may have both HDMI and Charger attached, or analog audio,
+ video, and USB cables attached simulteneously.
+
+ If there are cables mutually exclusive with each other,

+ If the extcon object has an optional callback "show_state"
+ defined, the showing function is overriden with the optional
+ callback.
+
+ If the default callback for showing function is used, the
+ format is like this:
+ # cat state
+ USB_OTG=1
+ HDMI=0
+ TA=1
+ EAR_JACK=0
+ #
+ In this example, the extcon device have USB_OTG and TA
+ cables attached and HDMI and EAR_JACK cables detached.
+
+ In order to update the state of an extcon device, enter a hex
+ state number starting with 0x.
+ echo 0xHEX > state
+
+ This updates the whole state of the extcon dev.
+ Inputs of all the methods are required to meet the
+ mutually_exclusive contidions if they exist.
+
+ It is recommended to use this "global" state interface if
+ you need to enter the value atomically. The later state
+ interface associated with each cable cannot update
+ multiple cable states of an extcon device simultaneously.

-Release Notes for Linux on Intel's IXP2000 Network Processor
-
-Maintained by Deepak Saxena <dsaxena@plexity.net>
--------------------------------------------------------------------------
-
-1. Overview
-
-Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed
-for high-performance network applications such high-availability
-telecom systems. In addition to an XScale core, it contains up to 8
-"MicroEngines" that run special code, several high-end networking
-interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port,
-flash interface, and some other odds and ends. For more information, see:
-
-http://developer.intel.com
-
-2. Linux Support
-
-Linux currently supports the following features on the IXP2000 NPUs:
-
-- On-chip serial
-- PCI
-- Flash (MTD/JFFS2)
-- I2C through GPIO
-- Timers (watchdog, OS)
-
-That is about all we can support under Linux ATM b/c the core networking
-components of the chip are accessed via Intel's closed source SDK.
-Please contact Intel directly on issues with using those. There is
-also a mailing list run by some folks at Princeton University that might
-be of help: https://lists.cs.princeton.edu/mailman/listinfo/ixp2xxx
-
-WHATEVER YOU DO, DO NOT POST EMAIL TO THE LINUX-ARM OR LINUX-ARM-KERNEL
-MAILING LISTS REGARDING THE INTEL SDK.
-
-3. Supported Platforms
-
-- Intel IXDP2400 Reference Platform
-- Intel IXDP2800 Reference Platform
-- Intel IXDP2401 Reference Platform
-- Intel IXDP2801 Reference Platform
-- RadiSys ENP-2611
-
-4. Usage Notes
-
-- The IXP2000 platforms usually have rather complex PCI bus topologies
- with large memory space requirements. In addition, b/c of the way the
- Intel SDK is designed, devices are enumerated in a very specific
- way. B/c of this this, we use "pci=firmware" option in the kernel
- command line so that we do not re-enumerate the bus.
-
-- IXDP2x01 systems have variable clock tick rates that we cannot determine
- via HW registers. The "ixdp2x01_clk=XXX" cmd line options allow you
- to pass the clock rate to the board port.
-
-5. Thanks
-
-The IXP2000 work has been funded by Intel Corp. and MontaVista Software, Inc.

+* Freescale IOMUX Controller (IOMUXC) for i.MX
+
+The IOMUX Controller (IOMUXC), together with the IOMUX, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+8 muxing options (called ALT modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the IOMUXC controls
+also the PAD settings parameters.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Freescale IMX pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and config
+of the pins in that group. The 'mux' selects the function mode(also named mux
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, open drain, drive strength, etc.
+
+Required properties for iomux controller:
+- compatible: "fsl,<soc>-iomuxc"
+ Please refer to each fsl,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- fsl,pins: two integers array, represents a group of pins mux and config
+ setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
+ pin working on a specific function, CONFIG is the pad setting value like
+ pull-up on this pin. Please refer to fsl,<soc>-pinctrl.txt for the valid
+ pins and functions of each SoC.
+
+Bits used for CONFIG:
+NO_PAD_CTL(1 << 31): indicate this pin does not need config.
+
+SION(1 << 30): Software Input On Field.
+Force the selected mux mode input path no matter of MUX_MODE functionality.
+By default the input path is determined by functionality of the selected
+mux mode (regular).
+
+Other bits are used for PAD setting.
+Please refer to each fsl,<soc>-pinctrl,txt binding doc for SoC specific part
+of bits definitions.
+
+NOTE:
+Some requirements for using fsl,imx-pinctrl binding:
+1. We have pin function node defined under iomux controller node to represent
+ what pinmux functions this SoC supports.
+2. The pin configuration node intends to work on a specific function should
+ to be defined under that specific function node.
+ The function node's name should represent well about what function
+ this group of pins in this pin configuration node are working on.
+3. The driver can use the function node's name and pin configuration node's
+ name describe the pin function and group hierarchy.
+ For example, Linux IMX pinctrl driver takes the function node's name
+ as the function name and pin configuration node's name as group name to
+ create the map table.
+4. Each pin configuration node should have a phandle, devices can set pins
+ configurations by referring to the phandle of that pin configuration node.
+
+Examples:
+usdhc@0219c000 { /* uSDHC4 */
+ fsl,card-wired;
+ vmmc-supply = <®_3p3v>;
+ status = "okay";
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_usdhc4_1>;
+};
+
+iomuxc@020e0000 {
+ compatible = "fsl,imx6q-iomuxc";
+ reg = <0x020e0000 0x4000>;
+
+ /* shared pinctrl settings */
+ usdhc4 {
+ pinctrl_usdhc4_1: usdhc4grp-1 {
+ fsl,pins = <1386 0x17059 /* MX6Q_PAD_SD4_CMD__USDHC4_CMD */
+ 1392 0x10059 /* MX6Q_PAD_SD4_CLK__USDHC4_CLK */
+ 1462 0x17059 /* MX6Q_PAD_SD4_DAT0__USDHC4_DAT0 */
+ 1470 0x17059 /* MX6Q_PAD_SD4_DAT1__USDHC4_DAT1 */
+ 1478 0x17059 /* MX6Q_PAD_SD4_DAT2__USDHC4_DAT2 */
+ 1486 0x17059 /* MX6Q_PAD_SD4_DAT3__USDHC4_DAT3 */
+ 1493 0x17059 /* MX6Q_PAD_SD4_DAT4__USDHC4_DAT4 */
+ 1501 0x17059 /* MX6Q_PAD_SD4_DAT5__USDHC4_DAT5 */
+ 1509 0x17059 /* MX6Q_PAD_SD4_DAT6__USDHC4_DAT6 */
+ 1517 0x17059>; /* MX6Q_PAD_SD4_DAT7__USDHC4_DAT7 */
+ };
+ };
+ ....
+};
+Refer to the IOMUXC controller chapter in imx6q datasheet,
+0x17059 means enable hysteresis, 47KOhm Pull Up, 50Mhz speed,
+80Ohm driver strength and Fast Slew Rate.
+User should refer to each SoC spec to set the correct value.
+
+TODO: when dtc macro support is available, we can change above raw data
+to dt macro which can get better readability in dts file.

+* Freescale MXS Pin Controller
+
+The pins controlled by mxs pin controller are organized in banks, each bank
+has 32 pins. Each pin has 4 multiplexing functions, and generally, the 4th
+function is GPIO. The configuration on the pins includes drive strength,
+voltage and pull-up.
+
+Required properties:
+- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl"
+- reg: Should contain the register physical address and length for the
+ pin controller.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+The node of mxs pin controller acts as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for
+a group of pins, and only affects those parameters that are explicitly listed.
+In other words, a subnode that describes a drive strength parameter implies no
+information about pull-up. For this reason, even seemingly boolean values are
+actually tristates in this binding: unspecified, off, or on. Unspecified is
+represented as an absent property, and off/on are represented as integer
+values 0 and 1.
+
+Those subnodes under mxs pin controller node will fall into two categories.
+One is to set up a group of pins for a function, both mux selection and pin
+configurations, and it's called group node in the binding document. The other
+one is to adjust the pin configuration for some particular pins that need a
+different configuration than what is defined in group node. The binding
+document calls this type of node config node.
+
+On mxs, there is no hardware pin group. The pin group in this binding only
+means a group of pins put together for particular peripheral to work in
+particular function, like SSP0 functioning as mmc0-8bit. That said, the
+group node should include all the pins needed for one function rather than
+having these pins defined in several group nodes. It also means each of
+"pinctrl-*" phandle in client device node should only have one group node
+pointed in there, while the phandle can have multiple config node referenced
+there to adjust configurations for some pins in the group.
+
+Required subnode-properties:
+- fsl,pinmux-ids: An integer array. Each integer in the array specify a pin
+ with given mux function, with bank, pin and mux packed as below.
+
+ [15..12] : bank number
+ [11..4] : pin number
+ [3..0] : mux selection
+
+ This integer with mux selection packed is used as an entity by both group
+ and config nodes to identify a pin. The mux selection in the integer takes
+ effects only on group node, and will get ignored by driver with config node,
+ since config node is only meant to set up pin configurations.
+
+ Valid values for these integers are listed below.
+
+- reg: Should be the index of the group nodes for same function. This property
+ is required only for group nodes, and should not be present in any config
+ nodes.
+
+Optional subnode-properties:
+- fsl,drive-strength: Integer.
+ 0: 4 mA
+ 1: 8 mA
+ 2: 12 mA
+ 3: 16 mA
+- fsl,voltage: Integer.
+ 0: 1.8 V
+ 1: 3.3 V
+- fsl,pull-up: Integer.
+ 0: Disable the internal pull-up
+ 1: Enable the internal pull-up
+
+Examples:
+
+pinctrl@80018000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx28-pinctrl";
+ reg = <0x80018000 2000>;
+
+ mmc0_8bit_pins_a: mmc0-8bit@0 {
+ reg = <0>;
+ fsl,pinmux-ids = <
+ 0x2000 0x2010 0x2020 0x2030
+ 0x2040 0x2050 0x2060 0x2070
+ 0x2080 0x2090 0x20a0>;
+ fsl,drive-strength = <1>;
+ fsl,voltage = <1>;
+ fsl,pull-up = <1>;
+ };
+
+ mmc_cd_cfg: mmc-cd-cfg {
+ fsl,pinmux-ids = <0x2090>;
+ fsl,pull-up = <0>;
+ };
+
+ mmc_sck_cfg: mmc-sck-cfg {
+ fsl,pinmux-ids = <0x20a0>;
+ fsl,drive-strength = <2>;
+ fsl,pull-up = <0>;
+ };
+};
+
+In this example, group node mmc0-8bit defines a group of pins for mxs SSP0
+to function as a 8-bit mmc device, with 8mA, 3.3V and pull-up configurations
+applied on all these pins. And config nodes mmc-cd-cfg and mmc-sck-cfg are
+adjusting the configuration for pins card-detection and clock from what group
+node mmc0-8bit defines. Only the configuration properties to be adjusted need
+to be listed in the config nodes.

+NVIDIA Tegra20 pinmux controller
+
+Required properties:
+- compatible: "nvidia,tegra20-pinmux"
+- reg: Should contain the register physical address and length for each of
+ the tri-state, mux, pull-up/down, and pad control register sets.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Tegra's pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, tristate, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function or tristate parameter. For this
+reason, even seemingly boolean values are actually tristates in this binding:
+unspecified, off, or on. Unspecified is represented as an absent property,
+and off/on are represented as integer values 0 and 1.
+
+Required subnode-properties:
+- nvidia,pins : An array of strings. Each string contains the name of a pin or
+ group. Valid values for these names are listed below.
+
+Optional subnode-properties:
+- nvidia,function: A string containing the name of the function to mux to the
+ pin or group. Valid values for function names are listed below. See the Tegra

+NVIDIA Tegra30 pinmux controller
+
+The Tegra30 pinctrl binding is very similar to the Tegra20 pinctrl binding,
+as described in nvidia,tegra20-pinmux.txt. In fact, this document assumes
+that binding as a baseline, and only documents the differences between the
+two bindings.
+
+Required properties:
+- compatible: "nvidia,tegra30-pinmux"
+- reg: Should contain the register physical address and length for each of
+ the pad control and mux registers.
+
+Tegra30 adds the following optional properties for pin configuration subnodes:
+- nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
+- nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
+- nvidia,lock: Integer. Lock the pin configuration against further changes
+ until reset. 0: no, 1: yes.
+- nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
+
+As with Tegra20, see the Tegra TRM for complete details regarding which groups
+support which functionality.
+
+Valid values for pin and group names are:
+
+ per-pin mux groups:
+
+ These all support nvidia,function, nvidia,tristate, nvidia,pull,
+ nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
+ nvidia,io-reset.

+== Introduction ==
+
+Hardware modules that control pin multiplexing or configuration parameters
+such as pull-up/down, tri-state, drive-strength etc are designated as pin
+controllers. Each pin controller must be represented as a node in device tree,
+just like any other hardware module.
+
+Hardware modules whose signals are affected by pin configuration are
+designated client devices. Again, each client device must be represented as a
+node in device tree, just like any other hardware module.
+
+For a client device to operate correctly, certain pin controllers must
+set up certain specific pin configurations. Some client devices need a
+single static pin configuration, e.g. set up during initialization. Others
+need to reconfigure pins at run-time, for example to tri-state pins when the
+device is inactive. Hence, each client device can define a set of named
+states. The number and names of those states is defined by the client device's
+own binding.
+
+The common pinctrl bindings defined in this file provide an infrastructure
+for client device device tree nodes to map those state names to the pin
+configuration used by those states.
+
+Note that pin controllers themselves may also be client devices of themselves.
+For example, a pin controller may set up its own "active" state when the
+driver loads. This would allow representing a board's static pin configuration
+in a single place, rather than splitting it across multiple client device
+nodes. The decision to do this or not somewhat rests with the author of
+individual board device tree files, and any requirements imposed by the
+bindings for the individual client devices in use by that board, i.e. whether
+they require certain specific named states for dynamic pin configuration.
+
+== Pinctrl client devices ==
+
+For each client device individually, every pin state is assigned an integer
+ID. These numbers start at 0, and are contiguous. For each state ID, a unique
+property exists to define the pin configuration. Each state may also be
+assigned a name. When names are used, another property exists to map from
+those names to the integer IDs.
+
+Each client device's own binding determines the set of states the must be
+defined in its device tree node, and whether to define the set of state
+IDs that must be provided, or whether to define the set of state names that
+must be provided.
+
+Required properties:
+pinctrl-0: List of phandles, each pointing at a pin configuration
+ node. These referenced pin configuration nodes must be child
+ nodes of the pin controller that they configure. Multiple
+ entries may exist in this list so that multiple pin
+ controllers may be configured, or so that a state may be built
+ from multiple nodes for a single pin controller, each
+ contributing part of the overall configuration. See the next
+ section of this document for details of the format of these
+ pin configuration nodes.
+
+ In some cases, it may be useful to define a state, but for it
+ to be empty. This may be required when a common IP block is
+ used in an SoC either without a pin controller, or where the
+ pin controller does not affect the HW module in question. If
+ the binding for that IP block requires certain pin states to
+ exist, they must still be defined, but may be left empty.
+
+Optional properties:
+pinctrl-1: List of phandles, each pointing at a pin configuration
+ node within a pin controller.
+...
+pinctrl-n: List of phandles, each pointing at a pin configuration
+ node within a pin controller.
+pinctrl-names: The list of names to assign states. List entry 0 defines the
+ name for integer state ID 0, list entry 1 for state ID 1, and
+ so on.
+
+For example:
+
+ /* For a client device requiring named states */
+ device {
+ pinctrl-names = "active", "idle";
+ pinctrl-0 = <&state_0_node_a>;
+ pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+ };
+
+ /* For the same device if using state IDs */
+ device {
+ pinctrl-0 = <&state_0_node_a>;
+ pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+ };
+
+ /*
+ * For an IP block whose binding supports pin configuration,
+ * but in use on an SoC that doesn't have any pin control hardware
+ */
+ device {
+ pinctrl-names = "active", "idle";
+ pinctrl-0 = <>;
+ pinctrl-1 = <>;
+ };
+
+== Pin controller devices ==
+
+Pin controller devices should contain the pin configuration nodes that client
+devices reference.
+
+For example:
+
+ pincontroller {
+ ... /* Standard DT properties for the device itself elided */
+
+ state_0_node_a {
+ ...
+ };
+ state_1_node_a {
+ ...
+ };
+ state_1_node_b {
+ ...
+ };
+ }
+
+The contents of each of those pin configuration child nodes is defined
+entirely by the binding for the individual pin controller device. There
+exists no common standard for this content.
+
+The pin configuration nodes need not be direct children of the pin controller
+device; they may be grandchildren, for example. Whether this is legal, and
+whether there is any interaction between the child and intermediate parent
+nodes, is again defined entirely by the binding for the individual pin
+controller device.

Controlling dynamic debug Behaviour
===================================
The behaviour of pr_debug()/dev_dbg()s are controlled via writing to a

+Debug messages during Boot Process
==================================
-To be able to activate debug messages during the boot process,
-even before userspace and debugfs exists, use the boot parameter:
-ddebug_query="QUERY"
+To activate debug messages for core code and built-in modules during
+the boot process, even before userspace and debugfs exists, use
+dyndbg="QUERY", module.dyndbg="QUERY", or ddebug_query="QUERY"
+(ddebug_query is obsoleted by dyndbg, and deprecated). QUERY follows
+the syntax described above, but must not exceed 1023 characters. Your
+bootloader may impose lower limits.
-QUERY follows the syntax described above, but must not exceed 1023
-characters. The enablement of debug messages is done as an arch_initcall.
-Thus you can enable debug messages in all code processed after this
-arch_initcall via this boot parameter.
+These dyndbg params are processed just after the ddebug tables are
+processed, as part of the arch_initcall. Thus you can enable debug
+messages in all code run after this arch_initcall via this boot
+parameter.
+
On an x86 system for example ACPI enablement is a subsys_initcall and
-ddebug_query="file ec.c +p"
+ dyndbg="file ec.c +p"
will show early Embedded Controller transactions during ACPI setup if
your machine (typically a laptop) has an Embedded Controller.
PCI (or other devices) initialization also is a hot candidate for using
this boot parameter for debugging purposes.
+If foo module is not built-in, foo.dyndbg will still be processed at
+boot time, without effect, but will be reprocessed when module is
+loaded later. dyndbg_query= and bare dyndbg= are only processed at
+boot.
+
+
+Debug Messages at Module Initialization Time
+============================================
+
+When "modprobe foo" is called, modprobe scans /proc/cmdline for
+foo.params, strips "foo.", and passes them to the kernel along with
+params given in modprobe args or /etc/modprob.d/*.conf files,
+in the following order:
+
+1. # parameters given via /etc/modprobe.d/*.conf
+ options foo dyndbg=+pt
+ options foo dyndbg # defaults to +p
+
+2. # foo.dyndbg as given in boot args, "foo." is stripped and passed
+ foo.dyndbg=" func bar +p; func buz +mp"
+
+3. # args to modprobe
+ modprobe foo dyndbg==pmf # override previous settings
+
+These dyndbg queries are applied in order, with last having final say.
+This allows boot args to override or modify those from /etc/modprobe.d
+(sensible, since 1 is system wide, 2 is kernel or boot specific), and
+modprobe args to override both.
+
+In the foo.dyndbg="QUERY" form, the query must exclude "module foo".
+"foo" is extracted from the param-name, and applied to each query in
+"QUERY", and only 1 match-spec of each type is allowed.
+
+The dyndbg option is a "fake" module parameter, which means:
+
+- modules do not need to define it explicitly
+- every module gets it tacitly, whether they use pr_debug or not
+- it doesnt appear in /sys/module/$module/parameters/
+ To see it, grep the control file, or inspect /proc/cmdline.
+
+For CONFIG_DYNAMIC_DEBUG kernels, any settings given at boot-time (or
+enabled by -DDEBUG flag during compilation) can be disabled later via
+the sysfs interface if the debug messages are no longer needed:
+
+ echo "module module_name -p" > <debugfs>/dynamic_debug/control

+/*****************************************************************
+ * CHAPTER 1. *
+ * PORTING SWITCH CLASS DEVICE DRIVERS *
+ *****************************************************************/
+
+****** STEP 1. Basic Functionality
+ No extcon extended feature, but switch features only.
+
+- struct switch_dev (fed to switch_dev_register/unregister)
+ @name: no change
+ @dev: no change
+ @index: drop (not used in switch device driver side anyway)
+ @state: no change
+ If you have used @state with magic numbers, keep it
+ at this step.
+ @print_name: no change but type change (switch_dev->extcon_dev)
+ @print_state: no change but type change (switch_dev->extcon_dev)
+
+- switch_dev_register(sdev, dev)
+ => extcon_dev_register(edev, dev)
+ : no change but type change (sdev->edev)
+- switch_dev_unregister(sdev)
+ => extcon_dev_unregister(edev)
+ : no change but type change (sdev->edev)
+- switch_get_state(sdev)
+ => extcon_get_state(edev)
+ : no change but type change (sdev->edev) and (return: int->u32)
+- switch_set_state(sdev, state)
+ => extcon_set_state(edev, state)
+ : no change but type change (sdev->edev) and (state: int->u32)
+
+With this changes, the ex-switch extcon class device works as it once
+worked as switch class device. However, it will now have additional
+interfaces (both ABI and in-kernel API) and different ABI locations.
+However, if CONFIG_ANDROID is enabled without CONFIG_ANDROID_SWITCH,
+/sys/class/switch/* will be symbolically linked to /sys/class/extcon/
+so that they are still compatible with legacy userspace processes.
+
+****** STEP 2. Multistate (no more magic numbers in state value)
+ Extcon's extended features for switch device drivers with
+ complex features usually required magic numbers in state
+ value of switch_dev. With extcon, such magic numbers that
+ support multiple cables (
+
+ 1. Define cable names at edev->supported_cable.
+ 2. (Recommended) remove print_state callback.
+ 3. Use extcon_get_cable_state_(edev, index) or
+ extcon_get_cable_state(edev, cable_name) instead of
+ extcon_get_state(edev) if you intend to get a state of a specific
+ cable. Same for set_state. This way, you can remove the usage of
+ magic numbers in state value.
+ 4. Use extcon_update_state() if you are updating specific bits of
+ the state value.
+
+Example: a switch device driver w/ magic numbers for two cables.
+ "0x00": no cables connected.
+ "0x01": cable 1 connected
+ "0x02": cable 2 connected
+ "0x03": cable 1 and 2 connected
+ 1. edev->supported_cable = {"1", "2", NULL};
+ 2. edev->print_state = NULL;
+ 3. extcon_get_cable_state_(edev, 0) shows cable 1's state.
+ extcon_get_cable_state(edev, "1") shows cable 1's state.
+ extcon_set_cable_state_(edev, 1) sets cable 2's state.
+ extcon_set_cable_state(edev, "2") sets cable 2's state
+ 4. extcon_update_state(edev, 0x01, 0) sets the least bit's 0.
+
+****** STEP 3. Notify other device drivers
+
+ You can notify others of the cable attach/detach events with
+notifier chains.
+
+ At the side of other device drivers (the extcon device itself
+does not need to get notified of its own events), there are two
+methods to register notifier_block for cable events:
+(a) for a specific cable or (b) for every cable.
+
+ (a) extcon_register_interest(obj, extcon_name, cable_name, nb)
+ Example: want to get news of "MAX8997_MUIC"'s "USB" cable
+
+ obj = kzalloc(sizeof(struct extcon_specific_cable_nb),
+ GFP_KERNEL);
+ nb->notifier_call = the_callback_to_handle_usb;
+
+ extcon_register_intereset(obj, "MAX8997_MUIC", "USB", nb);
+
+ (b) extcon_register_notifier(edev, nb)
+ Call nb for any changes in edev.
+
+ Please note that in order to properly behave with method (a),
+the extcon device driver should support multistate feature (STEP 2).
+
+****** STEP 4. Inter-cable relation (mutually exclusive)
+
+ You can provide inter-cable mutually exclusiveness information
+for an extcon device. When cables A and B are declared to be mutually
+exclusive, the two cables cannot be in ATTACHED state simulteneously.
+
+
+/*****************************************************************
+ * CHAPTER 2. *
+ * PORTING USERSPACE w/ SWITCH CLASS DEVICE SUPPORT *
+ *****************************************************************/
+
+****** ABI Location
+
+ If "CONFIG_ANDROID" is enabled and "CONFIG_ANDROID_SWITCH" is
+disabled, /sys/class/switch/* are created as symbolic links to
+/sys/class/extcon/*. Because CONFIG_ANDROID_SWITCH creates
+/sys/class/switch directory, we disable symboling linking if
+CONFIG_ANDROID_SWITCH is enabled.
+
+ The two files of switch class, name and state, are provided with
+extcon, too. When the multistate support (STEP 2 of CHAPTER 1.) is
+not enabled or print_state callback is supplied, the output of
+state ABI is same with switch class.

glock is used in conjunction with the i_nlink field in the inode to
determine the lifetime of the inode in question. Locking of inodes
is on a per-inode basis. Locking of rgrps is on a per rgrp basis.
+In general we prefer to lock local locks prior to cluster locks.
+
+ Glock Statistics
+ ------------------
+
+The stats are divided into two sets: those relating to the
+super block and those relating to an individual glock. The
+super block stats are done on a per cpu basis in order to
+try and reduce the overhead of gathering them. They are also
+further divided by glock type. All timings are in nanoseconds.
+
+In the case of both the super block and glock statistics,
+the same information is gathered in each case. The super
+block timing statistics are used to provide default values for
+the glock timing statistics, so that newly created glocks
+should have, as far as possible, a sensible starting point.
+The per-glock counters are initialised to zero when the
+glock is created. The per-glock statistics are lost when
+the glock is ejected from memory.
+
+The statistics are divided into three pairs of mean and
+variance, plus two counters. The mean/variance pairs are
+smoothed exponential estimates and the algorithm used is
+one which will be very familiar to those used to calculation
+of round trip times in network code. See "TCP/IP Illustrated,
+Volume 1", W. Richard Stevens, sect 21.3, "Round-Trip Time Measurement",
+p. 299 and onwards. Also, Volume 2, Sect. 25.10, p. 838 and onwards.
+Unlike the TCP/IP Illustrated case, the mean and variance are
+not scaled, but are in units of integer nanoseconds.
+
+The three pairs of mean/variance measure the following
+things:
+
+ 1. DLM lock time (non-blocking requests)
+ 2. DLM lock time (blocking requests)
+ 3. Inter-request time (again to the DLM)
+
+A non-blocking request is one which will complete right
+away, whatever the state of the DLM lock in question. That
+currently means any requests when (a) the current state of
+the lock is exclusive, i.e. a lock demotion (b) the requested
+state is either null or unlocked (again, a demotion) or (c) the
+"try lock" flag is set. A blocking request covers all the other
+lock requests.
+
+There are two counters. The first is there primarily to show
+how many lock requests have been made, and thus how much data
+has gone into the mean/variance calculations. The other counter
+is counting queuing of holders at the top layer of the glock
+code. Hopefully that number will be a lot larger than the number
+of dlm lock requests issued.
+
+So why gather these statistics? There are several reasons
+we'd like to get a better idea of these timings:
+
+1. To be able to better set the glock "min hold time"
+2. To spot performance issues more easily
+3. To improve the algorithm for selecting resource groups for
+allocation (to base it on lock wait time, rather than blindly
+using a "try lock")
+
+Due to the smoothing action of the updates, a step change in
+some input quantity being sampled will only fully be taken
+into account after 8 samples (or 4 for the variance) and this
+needs to be carefully considered when interpreting the
+results.
+
+Knowing both the time it takes a lock request to complete and
+the average time between lock requests for a glock means we
+can compute the total percentage of the time for which the
+node is able to use a glock vs. time that the rest of the
+cluster has its share. That will be very useful when setting
+the lock min hold time.
+
+Great care has been taken to ensure that we
+measure exactly the quantities that we want, as accurately
+as possible. There are always inaccuracies in any
+measuring system, but I hope this is as accurate as we
+can reasonably make it.
+
+Per sb stats can be found here:
+/sys/kernel/debug/gfs2/<fsname>/sbstats
+Per glock stats can be found here:
+/sys/kernel/debug/gfs2/<fsname>/glstats
+
+Assuming that debugfs is mounted on /sys/kernel/debug and also
+that <fsname> is replaced with the name of the gfs2 filesystem
+in question.
+
+The abbreviations used in the output as are follows:
+
+srtt - Smoothed round trip time for non-blocking dlm requests
+srttvar - Variance estimate for srtt
+srttb - Smoothed round trip time for (potentially) blocking dlm requests
+srttvarb - Variance estimate for srttb
+sirt - Smoothed inter-request time (for dlm requests)
+sirtvar - Variance estimate for sirt
+dlm - Number of dlm requests made (dcnt in glstats file)
+queue - Number of glock requests queued (qcnt in glstats file)
+
+The sbstats file contains a set of these stats for each glock type (so 8 lines
+for each type) and for each cpu (one column per cpu). The glstats file contains
+a set of these stats for each glock in a similar format to the glocks file, but
+using the format mean/variance for each of the timing stats.
+
+The gfs2_glock_lock_time tracepoint prints out the current values of the stats
+for the glock in question, along with some addition information on each dlm
+reply that is received:
+
+status - The status of the dlm request
+flags - The dlm request flags
+tdiff - The time taken by this specific request
+(remaining fields as per above list)

+TI EMIF SDRAM Controller Driver:
+
+Author
+========
+Aneesh V <aneesh@ti.com>
+
+Location
+============

+
+Supported SoCs:
+===================
+TI OMAP44xx
+TI OMAP54xx
+
+Menuconfig option:
+==========================
+Device Drivers
+ Memory devices
+ Texas Instruments EMIF driver
+
+Description
+===========
+This driver is for the EMIF module available in Texas Instruments
+SoCs. EMIF is an SDRAM controller that, based on its revision,
+supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.
+This driver takes care of only LPDDR2 memories presently. The
+functions of the driver includes re-configuring AC timing
+parameters and other settings during frequency, voltage and
+temperature changes
+
+Platform Data (see include/linux/platform_data/emif_plat.h):
+=====================================================================
+DDR device details and other board dependent and SoC dependent
+information can be passed through platform data (struct emif_platform_data)
+- DDR device details: 'struct ddr_device_info'
+- Device AC timings: 'struct lpddr2_timings' and 'struct lpddr2_min_tck'
+- Custom configurations: customizable policy options through
+ 'struct emif_custom_configs'
+- IP revision
+- PHY type
+
+Interface to the external world:
+================================
+EMIF driver registers notifiers for voltage and frequency changes
+affecting EMIF and takes appropriate actions when these are invoked.
+- freq_pre_notify_handling()
+- freq_post_notify_handling()
+- volt_notify_handling()
+
+Debugfs
+========
+The driver creates two debugfs entries per device.
+- regcache_dump : dump of register values calculated and saved for all
+ frequencies used so far.
+- mr4 : last polled value of MR4 register in the LPDDR2 device. MR4
+ indicates the current temperature level of the device.

- Terry Murphy from 3Com for tech docs and support,
- Adam D. Ligas for testing the driver.
-
-Note:
- This driver will NOT work with the 3C339 Token Ring cards, you need
-to use the tms380 driver instead.
-
-Options:
-
-The driver accepts three options: ringspeed, pkt_buf_sz and message_level.
-
-These options can be specified differently for each card found.
-
-ringspeed: Has one of three settings 0 (default), 4 or 16. 0 will
-make the card autosense the ringspeed and join at the appropriate speed,
-this will be the default option for most people. 4 or 16 allow you to
-explicitly force the card to operate at a certain speed. The card will fail
-if you try to insert it at the wrong speed. (Although some hubs will allow
-this so be *very* careful). The main purpose for explicitly setting the ring
-speed is for when the card is first on the ring. In autosense mode, if the card
-cannot detect any active monitors on the ring it will open at the same speed as
-its last opening. This can be hazardous if this speed does not match the speed
-you want the ring to operate at.
-
-pkt_buf_sz: This is this initial receive buffer allocation size. This will
-default to 4096 if no value is entered. You may increase performance of the
-driver by setting this to a value larger than the network packet size, although
-the driver now re-sizes buffers based on MTU settings as well.
-
-message_level: Controls level of messages created by the driver. Defaults to 0:
-which only displays start-up and critical messages. Presently any non-zero
-value will display all soft messages as well. NB This does not turn
-debugging messages on, that must be done by modified the source code.
-
-Variable MTU size:
-
-The driver can handle a MTU size up to either 4500 or 18000 depending upon
-ring speed. The driver also changes the size of the receive buffers as part
-of the mtu re-sizing, so if you set mtu = 18000, you will need to be able
-to allocate 16 * (sk_buff with 18000 buffer size) call it 18500 bytes per ring
-position = 296,000 bytes of memory space, plus of course anything
-necessary for the tx sk_buff's. Remember this is per card, so if you are
-building routers, gateway's etc, you could start to use a lot of memory
-real fast.

+Device drivers API
+==================

+The include/net/mac802154.h defines following functions:
+ - struct ieee802154_dev *ieee802154_alloc_device

-Erik De Cock, Adrian Bridgett and Frank Fiene for their
-patience and testing.
-Donald Champion for the cardbus support
-Kyle Lucke for the dma api changes.
-Jonathon Bitner for hardware support.
-Everybody on linux-tr for their continued support.
-
-Options:
-
-The driver accepts four options: ringspeed, pkt_buf_sz,
-message_level and network_monitor.
-
-These options can be specified differently for each card found.
-
-ringspeed: Has one of three settings 0 (default), 4 or 16. 0 will
-make the card autosense the ringspeed and join at the appropriate speed,
-this will be the default option for most people. 4 or 16 allow you to
-explicitly force the card to operate at a certain speed. The card will fail
-if you try to insert it at the wrong speed. (Although some hubs will allow
-this so be *very* careful). The main purpose for explicitly setting the ring
-speed is for when the card is first on the ring. In autosense mode, if the card
-cannot detect any active monitors on the ring it will not open, so you must
-re-init the card at the appropriate speed. Unfortunately at present the only
-way of doing this is rmmod and insmod which is a bit tough if it is compiled
-in the kernel.
-
-pkt_buf_sz: This is this initial receive buffer allocation size. This will
-default to 4096 if no value is entered. You may increase performance of the
-driver by setting this to a value larger than the network packet size, although
-the driver now re-sizes buffers based on MTU settings as well.
-
-message_level: Controls level of messages created by the driver. Defaults to 0:
-which only displays start-up and critical messages. Presently any non-zero
-value will display all soft messages as well. NB This does not turn
-debugging messages on, that must be done by modified the source code.
-
-network_monitor: Any non-zero value will provide a quasi network monitoring
-mode. All unexpected MAC frames (beaconing etc.) will be received
-by the driver and the source and destination addresses printed.
-Also an entry will be added in /proc/net called olympic_tr%d, where tr%d
-is the registered device name, i.e tr0, tr1, etc. This displays low
-level information about the configuration of the ring and the adapter.
-This feature has been designed for network administrators to assist in
-the diagnosis of network / ring problems. (This used to OLYMPIC_NETWORK_MONITOR,
-but has now changed to allow each adapter to be configured differently and
-to alleviate the necessity to re-compile olympic to turn the option on).
-
-Multi-card:
-
-The driver will detect multiple cards and will work with shared interrupts,
-each card is assigned the next token ring device, i.e. tr0 , tr1, tr2. The
-driver should also happily reside in the system with other drivers. It has
-been tested with ibmtr.c running, and I personally have had one Olicom PCI
-card and two IBM olympic cards (all on the same interrupt), all running
-together.
-
-Variable MTU size:
-
-The driver can handle a MTU size up to either 4500 or 18000 depending upon
-ring speed. The driver also changes the size of the receive buffers as part
-of the mtu re-sizing, so if you set mtu = 18000, you will need to be able
-to allocate 16 * (sk_buff with 18000 buffer size) call it 18500 bytes per ring
-position = 296,000 bytes of memory space, plus of course anything
-necessary for the tx sk_buff's. Remember this is per card, so if you are
-building routers, gateway's etc, you could start to use a lot of memory

-Text File for the SMC TokenCard TokenRing Linux driver (smctr.c).
- By Jay Schulist <jschlst@samba.org>
-
-The Linux SMC Token Ring driver works with the SMC TokenCard Elite (8115T)
-ISA and SMC TokenCard Elite/A (8115T/A) MCA adapters.
-
-Latest information on this driver can be obtained on the Linux-SNA WWW site.
-Please point your browser to: http://www.linux-sna.org
-
-This driver is rather simple to use. Select Y to Token Ring adapter support
-in the kernel configuration. A choice for SMC Token Ring adapters will
-appear. This drives supports all SMC ISA/MCA adapters. Choose this
-option. I personally recommend compiling the driver as a module (M), but if you
-you would like to compile it statically answer Y instead.
-
-This driver supports multiple adapters without the need to load multiple copies
-of the driver. You should be able to load up to 7 adapters without any kernel
-modifications, if you are in need of more please contact the maintainer of this
-driver.
-
-Load the driver either by lilo/loadlin or as a module. When a module using the
-following command will suffice for most:
-
-# modprobe smctr
-smctr.c: v1.00 12/6/99 by jschlst@samba.org
-tr0: SMC TokenCard 8115T at Io 0x300, Irq 10, Rom 0xd8000, Ram 0xcc000.
-
-Now just setup the device via ifconfig and set and routes you may have. After
-this you are ready to start sending some tokens.
-
-Errata:
-1). For anyone wondering where to pick up the SMC adapters please browse
- to http://www.smc.com
-
-2). If you are the first/only Token Ring Client on a Token Ring LAN, please
- specify the ringspeed with the ringspeed=[4/16] module option. If no
- ringspeed is specified the driver will attempt to autodetect the ring
- speed and/or if the adapter is the first/only station on the ring take
- the appropriate actions.
-
- NOTE: Default ring speed is 16MB UTP.
-
-3). PnP support for this adapter sucks. I recommend hard setting the
- IO/MEM/IRQ by the jumpers on the adapter. If this is not possible
- load the module with the following io=[ioaddr] mem=[mem_addr]
- irq=[irq_num].
-
- The following IRQ, IO, and MEM settings are supported.
-

-1. Adapters can be slow to open (~20 secs) and close (~5 secs), please be
- patient.
-2. This driver works very well when autoprobing for adapters. Why even
- think about those nasty io/int/dma settings of modprobe when the driver
- will do it all for you!
-
-This driver is rather simple to use. Select Y to Token Ring adapter support
-in the kernel configuration. A choice for SysKonnect Token Ring adapters will
-appear. This drives supports all SysKonnect ISA and PCI adapters. Choose this
-option. I personally recommend compiling the driver as a module (M), but if you
-you would like to compile it statically answer Y instead.
-
-This driver supports multiple adapters without the need to load multiple copies
-of the driver. You should be able to load up to 7 adapters without any kernel
-modifications, if you are in need of more please contact the maintainer of this
-driver.
-
-Load the driver either by lilo/loadlin or as a module. When a module using the
-following command will suffice for most:
-
-# modprobe sktr
-
-This will produce output similar to the following: (Output is user specific)
-
-sktr.c: v1.01 08/29/97 by Christoph Goos
-tr0: SK NET TR 4/16 PCI found at 0x6100, using IRQ 17.
-tr1: SK NET TR 4/16 PCI found at 0x6200, using IRQ 16.
-tr2: SK NET TR 4/16 ISA found at 0xa20, using IRQ 10 and DMA 5.
-
-Now just setup the device via ifconfig and set and routes you may have. After
-this you are ready to start sending some tokens.
-
-Errata:
-For anyone wondering where to pick up the SysKonnect adapters please browse

+HCI backend for NFC Core
+
+Author: Eric Lapuyade, Samuel Ortiz
+Contact: eric.lapuyade@intel.com, samuel.ortiz@intel.com
+
+General
+-------
+
+The HCI layer implements much of the ETSI TS 102 622 V10.2.0 specification. It
+enables easy writing of HCI-based NFC drivers. The HCI layer runs as an NFC Core
+backend, implementing an abstract nfc device and translating NFC Core API
+to HCI commands and events.
+
+HCI
+---
+
+HCI registers as an nfc device with NFC Core. Requests coming from userspace are
+routed through netlink sockets to NFC Core and then to HCI. From this point,
+they are translated in a sequence of HCI commands sent to the HCI layer in the
+host controller (the chip). The sending context blocks while waiting for the
+response to arrive.
+HCI events can also be received from the host controller. They will be handled
+and a translation will be forwarded to NFC Core as needed.
+HCI uses 2 execution contexts:
+- one if for executing commands : nfc_hci_msg_tx_work(). Only one command
+can be executing at any given moment.
+- one if for dispatching received events and responses : nfc_hci_msg_rx_work()
+
+HCI Session initialization:
+---------------------------
+
+The Session initialization is an HCI standard which must unfortunately
+support proprietary gates. This is the reason why the driver will pass a list
+of proprietary gates that must be part of the session. HCI will ensure all
+those gates have pipes connected when the hci device is set up.
+
+HCI Gates and Pipes
+-------------------
+
+A gate defines the 'port' where some service can be found. In order to access
+a service, one must create a pipe to that gate and open it. In this
+implementation, pipes are totally hidden. The public API only knows gates.
+This is consistent with the driver need to send commands to proprietary gates
+without knowing the pipe connected to it.
+
+Driver interface
+----------------
+
+A driver would normally register itself with HCI and provide the following
+entry points:
+
+struct nfc_hci_ops {
+ int (*open)(struct nfc_hci_dev *hdev);
+ void (*close)(struct nfc_hci_dev *hdev);
+ int (*xmit)(struct nfc_hci_dev *hdev, struct sk_buff *skb);
+ int (*start_poll)(struct nfc_hci_dev *hdev, u32 protocols);
+ int (*target_from_gate)(struct nfc_hci_dev *hdev, u8 gate,
+ struct nfc_target *target);
+};
+
+open() and close() shall turn the hardware on and off. xmit() shall simply
+write a frame to the chip. start_poll() is an optional entrypoint that shall
+set the hardware in polling mode. This must be implemented only if the hardware
+uses proprietary gates or a mechanism slightly different from the HCI standard.
+target_from_gate() is another optional entrypoint to return the protocols
+corresponding to a proprietary gate.
+
+On the rx path, the driver is responsible to push incoming HCP frames to HCI
+using nfc_hci_recv_frame(). HCI will take care of re-aggregation and handling
+This must be done from a context that can sleep.
+
+SHDLC
+-----
+
+Most chips use shdlc to ensure integrity and delivery ordering of the HCP
+frames between the host controller (the chip) and hosts (entities connected
+to the chip, like the cpu). In order to simplify writing the driver, an shdlc
+layer is available for use by the driver.
+When used, the driver actually registers with shdlc, and shdlc will register
+with HCI. HCI sees shdlc as the driver and thus send its HCP frames
+through shdlc->xmit.
+SHDLC adds a new execution context (nfc_shdlc_sm_work()) to run its state
+machine and handle both its rx and tx path.
+
+Included Drivers
+----------------
+
+An HCI based driver for an NXP PN544, connected through I2C bus, and using
+shdlc is included.
+
+Execution Contexts
+------------------
+
+The execution contexts are the following:
+- IRQ handler (IRQH):
+fast, cannot sleep. stores incoming frames into an shdlc rx queue
+
+- SHDLC State Machine worker (SMW)
+handles shdlc rx & tx queues. Dispatches HCI cmd responses.
+
+- HCI Tx Cmd worker (MSGTXWQ)
+Serialize execution of HCI commands. Complete execution in case of resp timeout.
+
+- HCI Rx worker (MSGRXWQ)
+Dispatches incoming HCI commands or events.
+
+- Syscall context from a userspace call (SYSCALL)
+Any entrypoint in HCI called from NFC Core
+
+Workflow executing an HCI command (using shdlc)
+-----------------------------------------------
+
+Executing an HCI command can easily be performed synchronously using the
+following API:
+
+int nfc_hci_send_cmd (struct nfc_hci_dev *hdev, u8 gate, u8 cmd,
+ const u8 *param, size_t param_len, struct sk_buff **skb)
+
+The API must be invoked from a context that can sleep. Most of the time, this
+will be the syscall context. skb will return the result that was received in
+the response.
+
+Internally, execution is asynchronous. So all this API does is to enqueue the
+HCI command, setup a local wait queue on stack, and wait_event() for completion.
+The wait is not interruptible because it is guaranteed that the command will
+complete after some short timeout anyway.
+
+MSGTXWQ context will then be scheduled and invoke nfc_hci_msg_tx_work().
+This function will dequeue the next pending command and send its HCP fragments
+to the lower layer which happens to be shdlc. It will then start a timer to be
+able to complete the command with a timeout error if no response arrive.
+
+SMW context gets scheduled and invokes nfc_shdlc_sm_work(). This function
+handles shdlc framing in and out. It uses the driver xmit to send frames and
+receives incoming frames in an skb queue filled from the driver IRQ handler.
+SHDLC I(nformation) frames payload are HCP fragments. They are agregated to
+form complete HCI frames, which can be a response, command, or event.
+
+HCI Responses are dispatched immediately from this context to unblock
+waiting command execution. Reponse processing involves invoking the completion
+callback that was provided by nfc_hci_msg_tx_work() when it sent the command.
+The completion callback will then wake the syscall context.
+
+Workflow receiving an HCI event or command
+------------------------------------------
+
+HCI commands or events are not dispatched from SMW context. Instead, they are
+queued to HCI rx_queue and will be dispatched from HCI rx worker
+context (MSGRXWQ). This is done this way to allow a cmd or event handler
+to also execute other commands (for example, handling the
+NFC_HCI_EVT_TARGET_DISCOVERED event from PN544 requires to issue an
+ANY_GET_PARAMETER to the reader A gate to get information on the target
+that was discovered).
+
+Typically, such an event will be propagated to NFC Core from MSGRXWQ context.

+ SECure COMPuting with filters
+ =============================
+
+Introduction
+------------
+
+A large number of system calls are exposed to every userland process
+with many of them going unused for the entire lifetime of the process.
+As system calls change and mature, bugs are found and eradicated. A
+certain subset of userland applications benefit by having a reduced set
+of available system calls. The resulting set reduces the total kernel
+surface exposed to the application. System call filtering is meant for
+use with those applications.
+
+Seccomp filtering provides a means for a process to specify a filter for
+incoming system calls. The filter is expressed as a Berkeley Packet
+Filter (BPF) program, as with socket filters, except that the data
+operated on is related to the system call being made: system call
+number and the system call arguments. This allows for expressive
+filtering of system calls using a filter program language with a long
+history of being exposed to userland and a straightforward data set.
+
+Additionally, BPF makes it impossible for users of seccomp to fall prey
+to time-of-check-time-of-use (TOCTOU) attacks that are common in system
+call interposition frameworks. BPF programs may not dereference
+pointers which constrains all filters to solely evaluating the system
+call arguments directly.
+
+What it isn't
+-------------
+
+System call filtering isn't a sandbox. It provides a clearly defined
+mechanism for minimizing the exposed kernel surface. It is meant to be
+a tool for sandbox developers to use. Beyond that, policy for logical
+behavior and information flow should be managed with a combination of
+other system hardening techniques and, potentially, an LSM of your
+choosing. Expressive, dynamic filters provide further options down this
+path (avoiding pathological sizes or selecting which of the multiplexed
+system calls in socketcall() is allowed, for instance) which could be
+construed, incorrectly, as a more complete sandboxing solution.
+
+Usage
+-----
+
+An additional seccomp mode is added and is enabled using the same
+prctl(2) call as the strict seccomp. If the architecture has
+CONFIG_HAVE_ARCH_SECCOMP_FILTER, then filters may be added as below:
+
+PR_SET_SECCOMP:
+ Now takes an additional argument which specifies a new filter
+ using a BPF program.
+ The BPF program will be executed over struct seccomp_data
+ reflecting the system call number, arguments, and other
+ metadata. The BPF program must then return one of the
+ acceptable values to inform the kernel which action should be
+ taken.
+
+ Usage:
+ prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER, prog);
+
+ The 'prog' argument is a pointer to a struct sock_fprog which
+ will contain the filter program. If the program is invalid, the
+ call will return -1 and set errno to EINVAL.
+
+ If fork/clone and execve are allowed by @prog, any child
+ processes will be constrained to the same filters and system
+ call ABI as the parent.
+
+ Prior to use, the task must call prctl(PR_SET_NO_NEW_PRIVS, 1) or
+ run with CAP_SYS_ADMIN privileges in its namespace. If these are not
+ true, -EACCES will be returned. This requirement ensures that filter
+ programs cannot be applied to child processes with greater privileges
+ than the task that installed them.
+
+ Additionally, if prctl(2) is allowed by the attached filter,
+ additional filters may be layered on which will increase evaluation
+ time, but allow for further decreasing the attack surface during
+ execution of a process.
+
+The above call returns 0 on success and non-zero on error.
+
+Return values
+-------------
+A seccomp filter may return any of the following values. If multiple
+filters exist, the return value for the evaluation of a given system
+call will always use the highest precedent value. (For example,
+SECCOMP_RET_KILL will always take precedence.)
+
+In precedence order, they are:
+
+SECCOMP_RET_KILL:
+ Results in the task exiting immediately without executing the
+ system call. The exit status of the task (status & 0x7f) will
+ be SIGSYS, not SIGKILL.
+
+SECCOMP_RET_TRAP:
+ Results in the kernel sending a SIGSYS signal to the triggering
+ task without executing the system call. The kernel will
+ rollback the register state to just before the system call
+ entry such that a signal handler in the task will be able to
+ inspect the ucontext_t->uc_mcontext registers and emulate
+ system call success or failure upon return from the signal
+ handler.
+
+ The SECCOMP_RET_DATA portion of the return value will be passed
+ as si_errno.
+
+ SIGSYS triggered by seccomp will have a si_code of SYS_SECCOMP.
+
+SECCOMP_RET_ERRNO:
+ Results in the lower 16-bits of the return value being passed
+ to userland as the errno without executing the system call.
+
+SECCOMP_RET_TRACE:
+ When returned, this value will cause the kernel to attempt to
+ notify a ptrace()-based tracer prior to executing the system
+ call. If there is no tracer present, -ENOSYS is returned to
+ userland and the system call is not executed.
+
+ A tracer will be notified if it requests PTRACE_O_TRACESECCOMP
+ using ptrace(PTRACE_SETOPTIONS). The tracer will be notified
+ of a PTRACE_EVENT_SECCOMP and the SECCOMP_RET_DATA portion of
+ the BPF program return value will be available to the tracer
+ via PTRACE_GETEVENTMSG.
+
+SECCOMP_RET_ALLOW:
+ Results in the system call being executed.
+
+If multiple filters exist, the return value for the evaluation of a
+given system call will always use the highest precedent value.
+
+Precedence is only determined using the SECCOMP_RET_ACTION mask. When
+multiple filters return values of the same precedence, only the
+SECCOMP_RET_DATA from the most recently installed filter will be
+returned.
+
+Pitfalls
+--------
+
+The biggest pitfall to avoid during use is filtering on system call
+number without checking the architecture value. Why? On any
+architecture that supports multiple system call invocation conventions,
+the system call numbers may vary based on the specific invocation. If
+the numbers in the different calling conventions overlap, then checks in
+the filters may be abused. Always check the arch value!
+
+Example
+-------
+
+The samples/seccomp/ directory contains both an x86-specific example
+and a more generic example of a higher level macro interface for BPF
+program generation.
+
+
+
+Adding architecture support
+-----------------------
+
+See arch/Kconfig for the authoritative requirements. In general, if an
+architecture supports both ptrace_event and seccomp, it will be able to
+support seccomp filter with minor fixup: SIGSYS support and seccomp return
+value checking. Then it must just add CONFIG_HAVE_ARCH_SECCOMP_FILTER
+to its arch-specific Kconfig.

-The command to set a Smack label on a file is:
+Smack uses extended attributes (xattrs) to store labels on filesystem
+objects. The attributes are stored in the extended attribute security
+name space. A process must have CAP_MAC_ADMIN to change any of these
+attributes.
+
+The extended attributes that Smack uses are:
+
+SMACK64
+ Used to make access control decisions. In almost all cases
+ the label given to a new filesystem object will be the label
+ of the process that created it.
+SMACK64EXEC
+ The Smack label of a process that execs a program file with
+ this attribute set will run with this attribute's value.
+SMACK64MMAP
+ Don't allow the file to be mmapped by a process whose Smack
+ label does not allow all of the access permitted to a process
+ with the label contained in this attribute. This is a very
+ specific use case for shared libraries.
+SMACK64TRANSMUTE
+ Can only have the value "TRUE". If this attribute is present
+ on a directory when an object is created in the directory and
+ the Smack rule (more below) that permitted the write access
+ to the directory includes the transmute ("t") mode the object
+ gets the label of the directory instead of the label of the
+ creating process. If the object being created is a directory
+ the SMACK64TRANSMUTE attribute is set as well.
+SMACK64IPIN
+ This attribute is only available on file descriptors for sockets.

+ decisions on packets being delivered to this socket.
+SMACK64IPOUT
+ This attribute is only available on file descriptors for sockets.
+ Use the Smack label in this attribute for access control
+ decisions on packets coming from this socket.
+
+There are multiple ways to set a Smack label on a file:
# attr -S -s SMACK64 -V "value" path
+ # chsmack -a value path
-NOTE: Smack labels are limited to 23 characters. The attr command
- does not enforce this restriction and can be used to set
- invalid Smack labels on files.
+A process can see the smack label it is running with by
+reading /proc/self/attr/current. A process with CAP_MAC_ADMIN
+can set the process smack by writing there.
-If you don't do anything special all users will get the floor ("_")
-label when they log in. If you do want to log in via the hacked ssh
-at other labels use the attr command to set the smack value on the
-home directory and its contents.

-BTFIXUP
--------
-
-To build new kernels you have to issue "make image". The ready kernel
-in ELF format is placed in arch/sparc/boot/image. Explanation is below.
-
-BTFIXUP is a unique feature of Linux/sparc among other architectures,
-developed by Jakub Jelinek (I think... Obviously David S. Miller took
-part, too). It allows to boot the same kernel at different
-sub-architectures, such as sun4c, sun4m, sun4d, where SunOS uses
-different kernels. This feature is convinient for people who you move
-disks between boxes and for distrution builders.
-
-To function, BTFIXUP must link the kernel "in the draft" first,
-analyze the result, write a special stub code based on that, and
-build the final kernel with the stub (btfix.o).
-
-Kai Germaschewski improved the build system of the kernel in the 2.5 series
-significantly. Unfortunately, the traditional way of running the draft
-linking from architecture specific Makefile before the actual linking
-by generic Makefile is nearly impossible to support properly in the
-new build system. Therefore, the way we integrate BTFIXUP with the
-build system was changed in 2.5.40. Now, generic Makefile performs
-the draft linking and stores the result in file vmlinux. Architecture
-specific post-processing invokes BTFIXUP machinery and final linking
-in the same way as other architectures do bootstraps.
-
-Implications of that change are as follows.
-
-1. Hackers must type "make image" now, instead of just "make", in the same
- way as s390 people do now. It is analogous to "make bzImage" on i386.
- This does NOT affect sparc64, you continue to use "make" to build sparc64
- kernels.
-
-2. vmlinux is not the final kernel, so RPM builders have to adjust
- their spec files (if they delivered vmlinux for debugging).
- System.map generated for vmlinux is still valid.
-
-3. Scripts that produce a.out images have to be changed. First, if they
- invoke make, they have to use "make image". Second, they have to pick up
- the new kernel in arch/sparc/boot/image instead of vmlinux.
-
-4. Since we are compliant with Kai's build system now, make -j is permitted.

+*How FunctionFS works*
+
+From kernel point of view it is just a composite function with some
+unique behaviour. It may be added to an USB configuration only after
+the user space driver has registered by writing descriptors and
+strings (the user space program has to provide the same information
+that kernel level composite functions provide when they are added to
+the configuration).
+
+This in particular means that the composite initialisation functions
+may not be in init section (ie. may not use the __init tag).
+
+From user space point of view it is a file system which when
+mounted provides an "ep0" file. User space driver need to
+write descriptors and strings to that file. It does not need
+to worry about endpoints, interfaces or strings numbers but
+simply provide descriptors such as if the function was the
+only one (endpoints and strings numbers starting from one and
+interface numbers starting from zero). The FunctionFS changes
+them as needed also handling situation when numbers differ in
+different configurations.
+
+When descriptors and strings are written "ep#" files appear
+(one for each declared endpoint) which handle communication on
+a single endpoint. Again, FunctionFS takes care of the real
+numbers and changing of the configuration (which means that
+"ep1" file may be really mapped to (say) endpoint 3 (and when
+configuration changes to (say) endpoint 2)). "ep0" is used
+for receiving events and handling setup requests.
+
+When all files are closed the function disables itself.
+
+What I also want to mention is that the FunctionFS is designed in such
+a way that it is possible to mount it several times so in the end
+a gadget could use several FunctionFS functions. The idea is that
+each FunctionFS instance is identified by the device name used
+when mounting.
+
+One can imagine a gadget that has an Ethernet, MTP and HID interfaces
+where the last two are implemented via FunctionFS. On user space
+level it would look like this:
+
+$ insmod g_ffs.ko idVendor=<ID> iSerialNumber=<string> functions=mtp,hid
+$ mkdir /dev/ffs-mtp && mount -t functionfs mtp /dev/ffs-mtp
+$ ( cd /dev/ffs-mtp && mtp-daemon ) &
+$ mkdir /dev/ffs-hid && mount -t functionfs hid /dev/ffs-hid
+$ ( cd /dev/ffs-hid && hid-daemon ) &
+
+On kernel level the gadget checks ffs_data->dev_name to identify
+whether it's FunctionFS designed for MTP ("mtp") or HID ("hid").
+
+If no "functions" module parameters is supplied, the driver accepts
+just one function with any name.
+
+When "functions" module parameter is supplied, only functions
+with listed names are accepted. In particular, if the "functions"
+parameter's value is just a one-element list, then the behaviour
+is similar to when there is no "functions" at all; however,
+only a function with the specified name is accepted.
+
+The gadget is registered only after all the declared function
+filesystems have been mounted and USB descriptors of all functions
+have been written to their ep0's.
+
+Conversely, the gadget is unregistered after the first USB function
+closes its endpoints.

+Appendix I: SCSI Host Device
+
+The virtio SCSI host device groups together one or more virtual
+logical units (such as disks), and allows communicating to them
+using the SCSI protocol. An instance of the device represents a
+SCSI host to which many targets and LUNs are attached.
+
+The virtio SCSI device services two kinds of requests:
+
+ command requests for a logical unit;
+
+ task management functions related to a logical unit, target or
+ command.
+
+The device is also able to send out notifications about added and
+removed logical units. Together, these capabilities provide a
+SCSI transport protocol that uses virtqueues as the transfer
+medium. In the transport protocol, the virtio driver acts as the
+initiator, while the virtio SCSI host provides one or more
+targets that receive and process the requests.

+ num_queues is the total number of request virtqueues exposed by

+
+ seg_max is the maximum number of segments that can be in a
+ command. A bidirectional command can include seg_max input
+ segments and seg_max output segments.
+
+ max_sectors is a hint to the guest about the maximum transfer

+
+ cmd_per_lun is a hint to the guest about the maximum number of
+ linked commands it should send to one LUN. The actual value
+ to be used is the minimum of cmd_per_lun and the virtqueue
+ size.
+
+ event_info_size is the maximum size that the device will fill
+ for buffers that the driver places in the eventq. The driver
+ should always put buffers at least of this size. It is

+
+ cdb_size is the maximum size of the CDB that the driver will

+ restored to the default when the device is reset.
+
+ max_channel, max_target and max_lun can be used by the driver

+
+ Device Initialization
+
+The initialization routine should first of all discover the
+device's virtqueues.
+
+If the driver uses the eventq, it should then place at least a

+
+The driver can immediately issue requests (for example, INQUIRY
+or REPORT LUNS) or task management functions (for example, I_T
+RESET).
+
+ Device Operation: request queues
+
+The driver queues requests to an arbitrary request queue, and

+
+The lun field addresses a target and logical unit in the
+virtio-scsi device's SCSI domain. The only supported format for
+the LUN field is: first byte set to 1, second byte set to target,
+third and fourth byte representing a single level LUN structure,
+followed by four zero bytes. With this representation, a
+virtio-scsi device can serve up to 256 targets and 16384 LUNs per
+target.
+
+The id field is the command identifier (“tag”).
+
+task_attr, prio and crn should be left to zero. task_attr defines
+the task attribute as in the table above, but all task attributes
+may be mapped to SIMPLE by the device; crn may also be provided
+by clients, but is generally expected to be 0. The maximum CRN
+value defined by the protocol is 255, since CRN is stored in an
+8-bit integer.
+
+All of these fields are defined in SAM. They are always
+read-only, as are the cdb and dataout field. The cdb_size is
+taken from the configuration space.
+
+sense and subsequent fields are always write-only. The sense_len
+field indicates the number of bytes actually written to the sense
+buffer. The residual field indicates the residual size,
+calculated as “data_length - number_of_transferred_bytes”, for
+read or write operations. For bidirectional commands, the
+number_of_transferred_bytes includes both read and written bytes.
+A residual field that is less than the size of datain means that
+the dataout field was processed entirely. A residual field that
+exceeds the size of datain means that the dataout field was
+processed partially and the datain field was not processed at
+all.
+
+The status byte is written by the device to be the status code as
+defined in SAM.
+
+The response byte is written by the device to be one of the
+following:
+
+ VIRTIO_SCSI_S_OK when the request was completed and the status
+ byte is filled with a SCSI status code (not necessarily
+ "GOOD").
+
+ VIRTIO_SCSI_S_OVERRUN if the content of the CDB requires
+ transferring more data than is available in the data buffers.
+
+ VIRTIO_SCSI_S_ABORTED if the request was cancelled due to an
+ ABORT TASK or ABORT TASK SET task management function.
+
+ VIRTIO_SCSI_S_BAD_TARGET if the request was never processed
+ because the target indicated by the lun field does not exist.
+
+ VIRTIO_SCSI_S_RESET if the request was cancelled due to a bus
+ or device reset (including a task management function).
+
+ VIRTIO_SCSI_S_TRANSPORT_FAILURE if the request failed due to a
+ problem in the connection between the host and the target
+ (severed link).
+
+ VIRTIO_SCSI_S_TARGET_FAILURE if the target is suffering a

+
+ VIRTIO_SCSI_S_NEXUS_FAILURE if the nexus is suffering a failure
+ but retrying on other paths might yield a different result.
+
+ VIRTIO_SCSI_S_BUSY if the request failed but retrying on the
+ same path should work.
+
+ VIRTIO_SCSI_S_FAILURE for other host or guest error. In
+ particular, if neither dataout nor datain is empty, and the
+ VIRTIO_SCSI_F_INOUT feature has not been negotiated, the
+ request will be immediately returned with a response equal to

+ By sending this command, the driver asks the device which

+ and A.6 of the SCSI MMC specification. The driver writes the
+ events it is interested in into the event_requested; the device
+ responds by writing the events that it supports into
+ event_actual.
+
+ The type is VIRTIO_SCSI_T_AN_QUERY. The lun and event_requested
+ fields are written by the driver. The event_actual and response
+ fields are written by the device.
+
+ No command-specific values are defined for the response byte.
+
+ Asynchronous notification subscription
+#define VIRTIO_SCSI_T_AN_SUBSCRIBE 2
+
+
+
+struct virtio_scsi_ctrl_an {
+
+ // Read-only part

+
+ u8 lun[8];
+
+ u32 event_requested;
+
+ // Write-only part
+
+ u32 event_actual;
+
+ u8 response;
+
+}
+
+ By sending this command, the driver asks the specified LUN to
+ report events for its physical interface, again as described in
+ the SCSI MMC specification. The driver writes the events it is
+ interested in into the event_requested; the device responds by
+ writing the events that it supports into event_actual.
+
+ Event types are the same as for the asynchronous notification
+ query message.
+
+ The type is VIRTIO_SCSI_T_AN_SUBSCRIBE. The lun and
+ event_requested fields are written by the driver. The
+ event_actual and response fields are written by the device.
+
+ No command-specific values are defined for the response byte.
+
+ Device Operation: eventq
+
+The eventq is used by the device to report information on logical
+units that are attached to it. The driver should always leave a
+few buffers ready in the eventq. In general, the device will not
+queue events to cope with an empty eventq, and will end up
+dropping events if it finds no buffer ready. However, when
+reporting events for many LUNs (e.g. when a whole target
+disappears), the device can throttle events to avoid dropping
+them. For this reason, placing 10-15 buffers on the event queue
+should be enough.
+
+Buffers are placed in the eventq and filled by the device when
+interesting events occur. The buffers should be strictly
+write-only (device-filled) and the size of the buffers should be
+at least the value given in the device's configuration
+information.
+
+Buffers returned by the device on the eventq will be referred to
+as "events" in the rest of this section. Events have the
+following format:
+
+#define VIRTIO_SCSI_T_EVENTS_MISSED 0x80000000
+
+
+
+struct virtio_scsi_event {
+
+ // Write-only part
+
+ u32 event;
+
+ ...
+
+}
+
+If bit 31 is set in the event field, the device failed to report
+an event due to missing buffers. In this case, the driver should
+poll the logical units for unit attention conditions, and/or do
+whatever form of bus scan is appropriate for the guest operating
+system.
+
+Other data that the device writes to the buffer depends on the
+contents of the event field. The following events are defined:
+
+ No event
+#define VIRTIO_SCSI_T_NO_EVENT 0
+
+ This event is fired in the following cases:
+
+ When the device detects in the eventq a buffer that is shorter
+ than what is indicated in the configuration field, it might
+ use it immediately and put this dummy value in the event
+ field. A well-written driver will never observe this
+ situation.
+
+ When events are dropped, the device may signal this event as
+ soon as the drivers makes a buffer available, in order to
+ request action from the driver. In this case, of course, this
+ event will be reported with the VIRTIO_SCSI_T_EVENTS_MISSED
+ flag.
+
+ Transport reset
+#define VIRTIO_SCSI_T_TRANSPORT_RESET 1
+
+
+
+struct virtio_scsi_event_reset {
+
+ // Write-only part
+
+ u32 event;
+
+ u8 lun[8];
+
+ u32 reason;
+
+}
+
+
+
+#define VIRTIO_SCSI_EVT_RESET_HARD 0
+
+#define VIRTIO_SCSI_EVT_RESET_RESCAN 1
+
+#define VIRTIO_SCSI_EVT_RESET_REMOVED 2
+
+ By sending this event, the device signals that a logical unit
+ on a target has been reset, including the case of a new device
+ appearing or disappearing on the bus.The device fills in all
+ fields. The event field is set to
+ VIRTIO_SCSI_T_TRANSPORT_RESET. The lun field addresses a
+ logical unit in the SCSI host.
+
+ The reason value is one of the three #define values appearing
+ above:
+
+ VIRTIO_SCSI_EVT_RESET_REMOVED (“LUN/target removed”) is used if
+ the target or logical unit is no longer able to receive
+ commands.
+
+ VIRTIO_SCSI_EVT_RESET_HARD (“LUN hard reset”) is used if the
+ logical unit has been reset, but is still present.
+
+ VIRTIO_SCSI_EVT_RESET_RESCAN (“rescan LUN/target”) is used if a
+ target or logical unit has just appeared on the device.
+
+ The “removed” and “rescan” events, when sent for LUN 0, may
+ apply to the entire target. After receiving them the driver
+ should ask the initiator to rescan the target, in order to
+ detect the case when an entire target has appeared or
+ disappeared. These two events will never be reported unless the
+ VIRTIO_SCSI_F_HOTPLUG feature was negotiated between the host
+ and the guest.
+
+ Events will also be reported via sense codes (this obviously
+ does not apply to newly appeared buses or targets, since the
+ application has never discovered them):
+
+ “LUN/target removed” maps to sense key ILLEGAL REQUEST, asc
+ 0x25, ascq 0x00 (LOGICAL UNIT NOT SUPPORTED)
+
+ “LUN hard reset” maps to sense key UNIT ATTENTION, asc 0x29
+ (POWER ON, RESET OR BUS DEVICE RESET OCCURRED)
+
+ “rescan LUN/target” maps to sense key UNIT ATTENTION, asc 0x3f,
+ ascq 0x0e (REPORTED LUNS DATA HAS CHANGED)
+
+ The preferred way to detect transport reset is always to use
+ events, because sense codes are only seen by the driver when it
+ sends a SCSI command to the logical unit or target. However, in
+ case events are dropped, the initiator will still be able to
+ synchronize with the actual state of the controller if the
+ driver asks the initiator to rescan of the SCSI bus. During the
+ rescan, the initiator will be able to observe the above sense
+ codes, and it will process them as if it the driver had
+ received the equivalent event.
+
+ Asynchronous notification
+#define VIRTIO_SCSI_T_ASYNC_NOTIFY 2
+
+
+
+struct virtio_scsi_event_an {
+
+ // Write-only part
+
+ u32 event;
+
+ u8 lun[8];
+
+ u32 reason;
+
+}
+
+ By sending this event, the device signals that an asynchronous
+ event was fired from a physical interface.
+
+ All fields are written by the device. The event field is set to
+ VIRTIO_SCSI_T_ASYNC_NOTIFY. The lun field addresses a logical
+ unit in the SCSI host. The reason field is a subset of the
+ events that the driver has subscribed to via the "Asynchronous
+ notification subscription" command.
+
+ When dropped events are reported, the driver should poll for
+ asynchronous events manually using SCSI commands.
+
+Appendix X: virtio-mmio
+
+Virtual environments without PCI support (a common situation in
+embedded devices models) might use simple memory mapped device (“
+virtio-mmio”) instead of the PCI device.
+
+The memory mapped virtio device behaviour is based on the PCI
+device specification. Therefore most of operations like device
+initialization, queues configuration and buffer transfers are
+nearly identical. Existing differences are described in the
+following sections.
+
+ Device Initialization
+
+Instead of using the PCI IO space for virtio header, the “
+virtio-mmio” device provides a set of memory mapped control
+registers, all 32 bits wide, followed by device-specific
+configuration space. The following list presents their layout:
+
+ Offset from the device base address | Direction | Name
+ Description
+
+ 0x000 | R | MagicValue
+ “virt” string.
+
+ 0x004 | R | Version
+ Device version number. Currently must be 1.
+
+ 0x008 | R | DeviceID
+ Virtio Subsystem Device ID (ie. 1 for network card).
+
+ 0x00c | R | VendorID
+ Virtio Subsystem Vendor ID.
+
+ 0x010 | R | HostFeatures
+ Flags representing features the device supports.
+ Reading from this register returns 32 consecutive flag bits,
+ first bit depending on the last value written to
+ HostFeaturesSel register. Access to this register returns bits HostFeaturesSel*32
+
+ to (HostFeaturesSel*32)+31
+, eg. feature bits 0 to 31 if
+ HostFeaturesSel is set to 0 and features bits 32 to 63 if
+ HostFeaturesSel is set to 1. Also see [sub:Feature-Bits]
+
+ 0x014 | W | HostFeaturesSel
+ Device (Host) features word selection.
+ Writing to this register selects a set of 32 device feature bits
+ accessible by reading from HostFeatures register. Device driver
+ must write a value to the HostFeaturesSel register before
+ reading from the HostFeatures register.
+
+ 0x020 | W | GuestFeatures
+ Flags representing device features understood and activated by
+ the driver.
+ Writing to this register sets 32 consecutive flag bits, first
+ bit depending on the last value written to GuestFeaturesSel
+ register. Access to this register sets bits GuestFeaturesSel*32
+
+ to (GuestFeaturesSel*32)+31
+, eg. feature bits 0 to 31 if
+ GuestFeaturesSel is set to 0 and features bits 32 to 63 if
+ GuestFeaturesSel is set to 1. Also see [sub:Feature-Bits]
+
+ 0x024 | W | GuestFeaturesSel
+ Activated (Guest) features word selection.
+ Writing to this register selects a set of 32 activated feature
+ bits accessible by writing to the GuestFeatures register.
+ Device driver must write a value to the GuestFeaturesSel
+ register before writing to the GuestFeatures register.
+
+ 0x028 | W | GuestPageSize
+ Guest page size.
+ Device driver must write the guest page size in bytes to the
+ register during initialization, before any queues are used.
+ This value must be a power of 2 and is used by the Host to
+ calculate Guest address of the first queue page (see QueuePFN).
+
+ 0x030 | W | QueueSel
+ Virtual queue index (first queue is 0).
+ Writing to this register selects the virtual queue that the
+ following operations on QueueNum, QueueAlign and QueuePFN apply
+ to.
+
+ 0x034 | R | QueueNumMax
+ Maximum virtual queue size.
+ Reading from the register returns the maximum size of the queue
+ the Host is ready to process or zero (0x0) if the queue is not
+ available. This applies to the queue selected by writing to
+ QueueSel and is allowed only when QueuePFN is set to zero
+ (0x0), so when the queue is not actively used.
+
+ 0x038 | W | QueueNum
+ Virtual queue size.
+ Queue size is a number of elements in the queue, therefore size
+ of the descriptor table and both available and used rings.
+ Writing to this register notifies the Host what size of the
+ queue the Guest will use. This applies to the queue selected by
+ writing to QueueSel.
+
+ 0x03c | W | QueueAlign
+ Used Ring alignment in the virtual queue.
+ Writing to this register notifies the Host about alignment
+ boundary of the Used Ring in bytes. This value must be a power
+ of 2 and applies to the queue selected by writing to QueueSel.
+
+ 0x040 | RW | QueuePFN
+ Guest physical page number of the virtual queue.
+ Writing to this register notifies the host about location of the
+ virtual queue in the Guest's physical address space. This value
+ is the index number of a page starting with the queue
+ Descriptor Table. Value zero (0x0) means physical address zero
+ (0x00000000) and is illegal. When the Guest stops using the
+ queue it must write zero (0x0) to this register.
+ Reading from this register returns the currently used page
+ number of the queue, therefore a value other than zero (0x0)
+ means that the queue is in use.
+ Both read and write accesses apply to the queue selected by
+ writing to QueueSel.
+
+ 0x050 | W | QueueNotify
+ Queue notifier.
+ Writing a queue index to this register notifies the Host that
+ there are new buffers to process in the queue.
+
+ 0x60 | R | InterruptStatus
+Interrupt status.
+Reading from this register returns a bit mask of interrupts
+ asserted by the device. An interrupt is asserted if the
+ corresponding bit is set, ie. equals one (1).
+
+ Bit 0 | Used Ring Update
+This interrupt is asserted when the Host has updated the Used
+ Ring in at least one of the active virtual queues.
+
+ Bit 1 | Configuration change
+This interrupt is asserted when configuration of the device has
+ changed.
+
+ 0x064 | W | InterruptACK
+ Interrupt acknowledge.
+ Writing to this register notifies the Host that the Guest
+ finished handling interrupts. Set bits in the value clear the
+ corresponding bits of the InterruptStatus register.
+
+ 0x070 | RW | Status
+ Device status.
+ Reading from this register returns the current device status
+ flags.
+ Writing non-zero values to this register sets the status flags,
+ indicating the Guest progress. Writing zero (0x0) to this
+ register triggers a device reset.
+ Also see [sub:Device-Initialization-Sequence]
+
+ 0x100+ | RW | Config
+ Device-specific configuration space starts at an offset 0x100
+ and is accessed with byte alignment. Its meaning and size
+ depends on the device and the driver.
+
+Virtual queue size is a number of elements in the queue,
+therefore size of the descriptor table and both available and
+used rings.
+
+The endianness of the registers follows the native endianness of
+the Guest. Writing to registers described as “R” and reading from
+registers described as “W” is not permitted and can cause
+undefined behavior.
+
+The device initialization is performed as described in [sub:Device-Initialization-Sequence]
+ with one exception: the Guest must notify the Host about its
+page size, writing the size in bytes to GuestPageSize register
+before the initialization is finished.
+
+The memory mapped virtio devices generate single interrupt only,
+therefore no special configuration is required.
+
+ Virtqueue Configuration
+
+The virtual queue configuration is performed in a similar way to
+the one described in [sec:Virtqueue-Configuration] with a few
+additional operations:
+
+ Select the queue writing its index (first queue is 0) to the
+ QueueSel register.
+
+ Check if the queue is not already in use: read QueuePFN
+ register, returned value should be zero (0x0).
+
+ Read maximum queue size (number of elements) from the
+ QueueNumMax register. If the returned value is zero (0x0) the
+ queue is not available.
+
+ Allocate and zero the queue pages in contiguous virtual memory,
+ aligning the Used Ring to an optimal boundary (usually page
+ size). Size of the allocated queue may be smaller than or equal
+ to the maximum size returned by the Host.
+
+ Notify the Host about the queue size by writing the size to
+ QueueNum register.
+
+ Notify the Host about the used alignment by writing its value
+ in bytes to QueueAlign register.
+
+ Write the physical number of the first page of the queue to the
+ QueuePFN register.
+
+The queue and the device are ready to begin normal operations
+now.
+
+ Device Operation
+
+The memory mapped virtio device behaves in the same way as
+described in [sec:Device-Operation], with the following
+exceptions:
+
+ The device is notified about new buffers available in a queue
+ by writing the queue index to register QueueNum instead of the
+ virtio header in PCI I/O space ([sub:Notifying-The-Device]).
+
+ The memory mapped virtio device is using single, dedicated
+ interrupt signal, which is raised when at least one of the
+ interrupts described in the InterruptStatus register
+ description is asserted. After receiving an interrupt, the
+ driver must read the InterruptStatus register to check what
+ caused the interrupt (see the register description). After the
+ interrupt is handled, the driver must acknowledge it by writing
+ a bit mask corresponding to the serviced interrupt to the
+ InterruptACK register.

- * IXDP2x00-common PCI init
- *
- * The IXDP2[48]00 has a horrid PCI bus layout. Basically the board
- * contains two NPUs (ingress and egress) connected over PCI, both running
- * instances of the kernel. So far so good. Peers on the PCI bus running
- * Linux is a common design in telecom systems. The problem is that instead
- * of all the devices being controlled by a single host, different
- * devices are controlled by different NPUs on the same bus, leading to
- * multiple hosts on the bus. The exact bus layout looks like:
- *
- * Bus 0
- * Master NPU <-------------------+-------------------> Slave NPU
- * |
- * |
- * P2P
- * |
- *
- * Bus 1 |
- * <--+------+---------+---------+------+-->
- * | | | | |
- * | | | | |
- * ... Dev PMC Media Eth0 Eth1 ...
- *
- * The master controls all but Eth1, which is controlled by the
- * slave. What this means is that the both the master and the slave
- * have to scan the bus, but only one of them can enumerate the bus.
- * In addition, after the bus is scanned, each kernel must remove
- * the device(s) it does not control from the PCI dev list otherwise
- * a driver on each NPU will try to manage it and we will have horrible
- * conflicts. Oh..and the slave NPU needs to see the master NPU
- * for Intel's drivers to work properly. Closed source drivers...
- *
- * The way we deal with this is fairly simple but ugly:
- *
- * 1) Let master scan and enumerate the bus completely.
- * 2) Master deletes Eth1 from device list.
- * 3) Slave scans bus and then deletes all but Eth1 (Eth0 on slave)
- * from device list.
- * 4) Find HW designers and LART them.
- *
- * The boards also do not do normal PCI IRQ routing, or any sort of
- * sensical swizzling, so we just need to check where on the bus a
- * device sits and figure out to which CPLD pin the interrupt is routed.
- * See ixdp2[48]00.c files.

- * In the following configuration :

- * - PRCM asserts idle_req to the USBHOST module ( This typically
- * happens when the system is going to a low power mode : all ports
- * have been suspended, the master part of the USBHOST module has
- * entered the standby state, and SW has cut the functional clocks)
- * - an USBHOST interrupt occurs before the module is able to answer
- * idle_ack, typically a remote wakeup IRQ.
- * Then the USB HOST module will enter a deadlock situation where it
- * is no more accessible nor functional.
- *
- * Workaround:
- * Don't use smart idle; use only force idle, hence HWMOD_SWSUP_SIDLE

+ * the clean + invalidate performed by v7_flush_dcache_all causes a bunch
+ * of cache lines with uninitialized data and uninitialized tags to get

+ * clean + invalidate, before jumping into the kernel.
+ *
+ * This funciton is cloned from arch/arm/mach-tegra/headsmp.S, and needs
+ * to be called for both secondary cores startup and primary core resume
+ * procedures. Ideally, it should be moved into arch/arm/mm/cache-v7.S.

- * Normally, with the shift-and-add approach, if both numbers are

- * x 32
- * ( 2 - ------ ) mod 2 * 2
- * 32
- * 2
- *
- * (the `mod 2' subtracts 1 from 1.bbbb). To avoid lots of 2^32s,

- * x * y = xy
- * -x * y = 2y - xy
- * x * -y = 2x - xy
- * -x * -y = 4 - 2x - 2y + xy

- * For signed multiplies, we subtract (x << 32) from the partial
- * product to fix this problem for negative multipliers (see mul.s).
- * Because of the way the shift into the partial product is calculated
- * (N xor V), this term is automatically removed for the multiplicand,
- * so we don't have to adjust.
- *
- * But for unsigned multiplies, the high order bit wasn't a sign bit,

- * Derived constants:
- * TOPBITS number of bits in the top decade of a number

- * R the remainder so far, initially the dividend
- * ITER number of main division loop iterations required;

- * A large dividend is one greater than 2^(31-TOPBITS) and takes a

+/* A note about branch offset calculations. The addrs[] array,

+ * sparc instructions emitted for that BPF instruction.
+ *
+ * The most common case is to emit a branch at the end of such
+ * a code sequence. So this would be two instructions, the
+ * branch and it's delay slot.
+ *
+ * Therefore by default the branch emitters calculate the branch
+ * offset field as:
+ *
+ * destination - (addrs[i] - 8)
+ *
+ * This "addrs[i] - 8" is the address of the branch itself or
+ * what "." would be in assembler notation. The "8" part is
+ * how we take into consideration the branch and it's delay
+ * slot mentioned above.
+ *
+ * Sometimes we need to emit a branch earlier in the code
+ * sequence. And in these situations we adjust "destination"
+ * to accomodate this difference. For example, if we needed
+ * to emit a branch (and it's delay slot) right before the
+ * final instruction emitted for a BPF opcode, we'd use
+ * "destination + 4" instead of just plain "destination" above.
+ *
+ * This is why you see all of these funny emit_branch() and
+ * emit_jump() calls with adjusted offsets.

* Omit this value, if all cards are interconnected or none is connected.
* If unsure, don't give this parameter.
*
- * dslot:
- * NOTE: only one dslot value must be given for every card.
- * Also this value must be given for non-E1 cards. If omitted, the E1
- * card has D-channel on time slot 16, which is default.
- * If 1..15 or 17..31, an alternate time slot is used for D-channel.
- * In this case, the application must be able to handle this.
- * If -1 is given, the D-channel is disabled and all 31 slots can be used
- * for B-channel. (only for specific applications)
+ * dmask and bmask:
+ * NOTE: One dmask value must be given for every HFC-E1 card.
+ * If omitted, the E1 card has D-channel on time slot 16, which is default.
+ * dmask is a 32 bit mask. The bit must be set for an alternate time slot.
+ * If multiple bits are set, multiple virtual card fragments are created.
+ * For each bit set, a bmask value must be given. Each bit on the bmask
+ * value stands for a B-channel. The bmask may not overlap with dmask or
+ * with other bmask values for that card.
+ * Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000
+ * This will create one fragment with D-channel on slot 1 with
+ * B-channels on slots 2..15, and a second fragment with D-channel
+ * on slot 17 with B-channels on slot 18..31. Slot 16 is unused.
+ * If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will
+ * not function.
+ * Example: dmask=0x00000001 bmask=0xfffffffe
+ * This will create a port with all 31 usable timeslots as
+ * B-channels.
+ * If no bits are set on bmask, no B-channel is created for that fragment.
+ * Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask)
+ * This will create 31 ports with one D-channel only.
* If you don't know how to use it, you don't need it!

- This driver supports the bmp085 digital barometric pressure
- and temperature sensor from Bosch Sensortec. The datasheet
- is available from their website:
- http://www.bosch-sensortec.com/content/language1/downloads/BST-BMP085-DS000-05.pdf
-
- A pressure measurement is issued by reading from pressure0_input.
- The return value ranges from 30000 to 110000 pascal with a resulution
- of 1 pascal (0.01 millibar) which enables measurements from 9000m above
- to 500m below sea level.
-
- The temperature can be read from temp0_input. Values range from
- -400 to 850 representing the ambient temperature in degree celsius
- multiplied by 10.The resolution is 0.1 celsius.
-
- Because ambient pressure is temperature dependent, a temperature
- measurement will be executed automatically even if the user is reading
- from pressure0_input. This happens if the last temperature measurement
- has been executed more then one second ago.
-
- To decrease RMS noise from pressure measurements, the bmp085 can
- autonomously calculate the average of up to eight samples. This is
- set up by writing to the oversampling sysfs file. Accepted values
- are 0, 1, 2 and 3. 2^x when x is the value written to this file
- specifies the number of samples used to calculate the ambient pressure.
- RMS noise is specified with six pascal (without averaging) and decreases
- down to 3 pascal when using an oversampling setting of 3.

-/* ne2.c: A NE/2 Ethernet Driver for Linux. */
-/*
- Based on the NE2000 driver written by Donald Becker (1992-94).
- modified by Wim Dumon (Apr 1996)
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- The author may be reached as wimpie@linux.cc.kuleuven.ac.be
-
- Currently supported: NE/2
- This patch was never tested on other MCA-ethernet adapters, but it
- might work. Just give it a try and let me know if you have problems.
- Also mail me if it really works, please!
-
- Changelog:
- Mon Feb 3 16:26:02 MET 1997
- - adapted the driver to work with the 2.1.25 kernel
- - multiple ne2 support (untested)
- - module support (untested)
-
- Fri Aug 28 00:18:36 CET 1998 (David Weinehall)
- - fixed a few minor typos
- - made the MODULE_PARM conditional (it only works with the v2.1.x kernels)
- - fixed the module support (Now it's working...)
-
- Mon Sep 7 19:01:44 CET 1998 (David Weinehall)
- - added support for Arco Electronics AE/2-card (experimental)
-
- Mon Sep 14 09:53:42 CET 1998 (David Weinehall)
- - added support for Compex ENET-16MC/P (experimental)
-
- Tue Sep 15 16:21:12 CET 1998 (David Weinehall, Magnus Jonsson, Tomas Ogren)
- - Miscellaneous bugfixes
-
- Tue Sep 19 16:21:12 CET 1998 (Magnus Jonsson)
- - Cleanup
-
- Wed Sep 23 14:33:34 CET 1998 (David Weinehall)
- - Restructuring and rewriting for v2.1.x compliance
-
- Wed Oct 14 17:19:21 CET 1998 (David Weinehall)
- - Added code that unregisters irq and proc-info
- - Version# bump
-
- Mon Nov 16 15:28:23 CET 1998 (Wim Dumon)
- - pass 'dev' as last parameter of request_irq in stead of 'NULL'
-
- Wed Feb 7 21:24:00 CET 2001 (Alfred Arnold)
- - added support for the D-Link DE-320CT
-
- * WARNING
- -------
- This is alpha-test software. It is not guaranteed to work. As a
- matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
- would like to hear from you if you use this driver, even if it works.
- If it doesn't work, be sure to send me a mail with the problems !

-/* smc-mca.c: A SMC Ultra ethernet driver for linux. */
-/*
- Most of this driver, except for ultramca_probe is nearly
- verbatim from smc-ultra.c by Donald Becker. The rest is
- written and copyright 1996 by David Weis, weisd3458@uni.edu
-
- This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
-
- This driver uses the cards in the 8390-compatible, shared memory mode.
- Most of the run-time complexity is handled by the generic code in
- 8390.c.
-
- This driver enables the shared memory only when doing the actual data
- transfers to avoid a bug in early version of the card that corrupted
- data transferred by a AHA1542.
-
- This driver does not support the programmed-I/O data transfer mode of
- the EtherEZ. That support (if available) is smc-ez.c. Nor does it
- use the non-8390-compatible "Altego" mode. (No support currently planned.)
-
- Changelog:
-
- Paul Gortmaker : multiple card support for module users.
- David Weis : Micro Channel-ized it.
- Tom Sightler : Added support for IBM PS/2 Ethernet Adapter/A
- Christopher Turcksin : Changed MCA-probe so that multiple adapters are
- found correctly (Jul 16, 1997)
- Chris Beauregard : Tried to merge the two changes above (Dec 15, 1997)
- Tom Sightler : Fixed minor detection bug caused by above merge
- Tom Sightler : Added support for three more Western Digital
- MCA-adapters
- Tom Sightler : Added support for 2.2.x mca_find_unused_adapter
- Hartmut Schmidt : - Modified parameter detection to handle each
- card differently depending on a switch-list
- - 'card_ver' removed from the adapter list
- - Some minor bug fixes

- Support for MCA EtherWORKS cards added 11-3-98.
+ Support for MCA EtherWORKS cards added 11-3-98. (MCA since deleted)
Verified to work with up to 2 DE212 cards in a system (although not
fully stress-tested).
- Currently known bugs/limitations:
-
- Note: with the MCA stuff as a module, it trusts the MCA configuration,
- not the command line for IRQ and memory address. You can
- specify them if you want, but it will throw your values out.
- You still have to pass the IO address it was configured as
- though.

-
- Changelog:
-
- Mike Cruse : mcruse@cti-ltd.com
- : Changes for Linux 2.0 compatibility.
- : Added dev_id parameter in net_interrupt(),
- : request_irq() and free_irq(). Just NULL for now.
-
- Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
- : in net_open() and net_close() so kerneld would know
- : that the module is in use and wouldn't eject the
- : driver prematurely.
-
- Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
- : as an example. Disabled autoprobing in init_module(),
- : not a good thing to do to other devices while Linux
- : is running from all accounts.
-
- Russ Nelson : Jul 13 1998. Added RxOnly DMA support.
-
- Melody Lee : Aug 10 1999. Changes for Linux 2.2.5 compatibility.
- : email: ethernet@crystal.cirrus.com
-
- Alan Cox : Removed 1.2 support, added 2.1 extra counters.
-
- Andrew Morton : Kernel 2.3.48
- : Handle kmalloc() failures
- : Other resource allocation fixes
- : Add SMP locks
- : Integrate Russ Nelson's ALLOW_DMA functionality back in.
- : If ALLOW_DMA is true, make DMA runtime selectable
- : Folded in changes from Cirrus (Melody Lee
- : <klee@crystal.cirrus.com>)
- : Don't call netif_wake_queue() in net_send_packet()
- : Fixed an out-of-mem bug in dma_rx()
- : Updated Documentation/networking/cs89x0.txt
-
- Andrew Morton : Kernel 2.3.99-pre1
- : Use skb_reserve to longword align IP header (two places)
- : Remove a delay loop from dma_rx()
- : Replace '100' with HZ
- : Clean up a couple of skb API abuses
- : Added 'cs89x0_dma=N' kernel boot option
- : Correctly initialise lp->lock in non-module compile
-
- Andrew Morton : Kernel 2.3.99-pre4-1
- : MOD_INC/DEC race fix (see
- : http://www.uwsg.indiana.edu/hypermail/linux/kernel/0003.3/1532.html)
-
- Andrew Morton : Kernel 2.4.0-test7-pre2
- : Enhanced EEPROM support to cover more devices,
- : abstracted IRQ mapping to support CONFIG_ARCH_CLPS7500 arch
- : (Jason Gunthorpe <jgg@ualberta.ca>)
-
- Andrew Morton : Kernel 2.4.0-test11-pre4
- : Use dev->name in request_*() (Andrey Panin)
- : Fix an error-path memleak in init_module()
- : Preserve return value from request_irq()
- : Fix type of `media' module parm (Keith Owens)
- : Use SET_MODULE_OWNER()
- : Tidied up strange request_irq() abuse in net_open().
-
- Andrew Morton : Kernel 2.4.3-pre1
- : Request correct number of pages for DMA (Hugh Dickens)
- : Select PP_ChipID _after_ unregister_netdev in cleanup_module()
- : because unregister_netdev() calls get_stats.
- : Make `version[]' __initdata
- : Uninlined the read/write reg/word functions.
-
- Oskar Schirmer : oskar@scara.com
- : HiCO.SH4 (superh) support added (irq#1, cs89x0_media=)
-
- Deepak Saxena : dsaxena@plexity.net
- : Intel IXDP2x01 (XScale ixp2x00 NPU) platform support
-

- net-3-driver for the 3c523 Etherlink/MC card (i82586 Ethernet chip)
-
-
- This is an extension to the Linux operating system, and is covered by the
- same GNU General Public License that covers that work.
-
- Copyright 1995, 1996 by Chris Beauregard (cpbeaure@undergrad.math.uwaterloo.ca)
-
- This is basically Michael Hipp's ni52 driver, with a new probing
- algorithm and some minor changes to the 82586 CA and reset routines.
- Thanks a lot Michael for a really clean i82586 implementation! Unless
- otherwise documented in ni52.c, any bugs are mine.
-
- Contrary to the Ethernet-HOWTO, this isn't based on the 3c507 driver in
- any way. The ni52 is a lot easier to modify.
-
- sources:
- ni52.c
-
- Crynwr packet driver collection was a great reference for my first
- attempt at this sucker. The 3c507 driver also helped, until I noticed
- that ni52.c was a lot nicer.
-
- EtherLink/MC: Micro Channel Ethernet Adapter Technical Reference
- Manual, courtesy of 3Com CardFacts, documents the 3c523-specific
- stuff. Information on CardFacts is found in the Ethernet HOWTO.
- Also see <a href="http://www.3com.com/">
-
- Microprocessor Communications Support Chips, T.J. Byers, ISBN
- 0-444-01224-9, has a section on the i82586. It tells you just enough
- to know that you really don't want to learn how to program the chip.
-
- The original device probe code was stolen from ps2esdi.c
-
- Known Problems:
- Since most of the code was stolen from ni52.c, you'll run across the
- same bugs in the 0.62 version of ni52.c, plus maybe a few because of
- the 3c523 idiosynchacies. The 3c523 has 16K of RAM though, so there
- shouldn't be the overrun problem that the 8K ni52 has.
-
- This driver is for a 16K adapter. It should work fine on the 64K
- adapters, but it will only use one of the 4 banks of RAM. Modifying
- this for the 64K version would require a lot of heinous bank
- switching, which I'm sure not interested in doing. If you try to
- implement a bank switching version, you'll basically have to remember
- what bank is enabled and do a switch every time you access a memory
- location that's not current. You'll also have to remap pointers on
- the driver side, because it only knows about 16K of the memory.
- Anyone desperate or masochistic enough to try?
-
- It seems to be stable now when multiple transmit buffers are used. I
- can't see any performance difference, but then I'm working on a 386SX.
-
- Multicast doesn't work. It doesn't even pretend to work. Don't use
- it. Don't compile your kernel with multicast support. I don't know
- why.
-
- Features:
- This driver is useable as a loadable module. If you try to specify an
- IRQ or a IO address (via insmod 3c523.o irq=xx io=0xyyy), it will
- search the MCA slots until it finds a 3c523 with the specified
- parameters.
-
- This driver does support multiple ethernet cards when used as a module
- (up to MAX_3C523_CARDS, the default being 4)
-
- This has been tested with both BNC and TP versions, internal and
- external transceivers. Haven't tested with the 64K version (that I
- know of).
-
- History:
- Jan 1st, 1996
- first public release
- Feb 4th, 1996
- update to 1.3.59, incorporated multicast diffs from ni52.c
- Feb 15th, 1996
- added shared irq support
- Apr 1999
- added support for multiple cards when used as a module
- added option to disable multicast as is causes problems
- Ganesh Sittampalam <ganesh.sittampalam@magdalen.oxford.ac.uk>
- Stuart Adamson <stuart.adamson@compsoc.net>
- Nov 2001
- added support for ethtool (jgarzik)

-/**
- * DOC: Traps for the unwary
- *
- * The diagram (Figure 1-1) and the POS summary disagree with the
- * "Interrupt Level" section in the manual.
- *
- * The manual contradicts itself when describing the minimum number
- * buffers in the 'configure lists' command.
- * My card accepts a buffer config of 4/4.
- *
- * Setting the SAV BP bit does not save bad packets, but
- * only enables RX on-card stats collection.
- *
- * The documentation in places seems to miss things. In actual fact
- * I've always eventually found everything is documented, it just
- * requires careful study.
- *
- * DOC: Theory Of Operation
- *
- * The 3com 3c527 is a 32bit MCA bus mastering adapter with a large
- * amount of on board intelligence that housekeeps a somewhat dumber
- * Intel NIC. For performance we want to keep the transmit queue deep
- * as the card can transmit packets while fetching others from main
- * memory by bus master DMA. Transmission and reception are driven by
- * circular buffer queues.
- *
- * The mailboxes can be used for controlling how the card traverses
- * its buffer rings, but are used only for initial setup in this
- * implementation. The exec mailbox allows a variety of commands to
- * be executed. Each command must complete before the next is
- * executed. Primarily we use the exec mailbox for controlling the
- * multicast lists. We have to do a certain amount of interesting
- * hoop jumping as the multicast list changes can occur in interrupt
- * state when the card has an exec command pending. We defer such
- * events until the command completion interrupt.
- *
- * A copy break scheme (taken from 3c59x.c) is employed whereby
- * received frames exceeding a configurable length are passed
- * directly to the higher networking layers without incuring a copy,
- * in what amounts to a time/space trade-off.
- *
- * The card also keeps a large amount of statistical information
- * on-board. In a perfect world, these could be used safely at no
- * cost. However, lacking information to the contrary, processing
- * them without races would involve so much extra complexity as to
- * make it unworthwhile to do so. In the end, a hybrid SW/HW
- * implementation was made necessary --- see mc32_update_stats().
- *
- * DOC: Notes
- *
- * It should be possible to use two or more cards, but at this stage
- * only by loading two copies of the same module.
- *
- * The on-board 82586 NIC has trouble receiving multiple
- * back-to-back frames and so is likely to drop packets from fast
- * senders.

+ * The 82599 and the X540 do not have true 64bit nanosecond scale
+ * counter registers. Instead, SYSTIME is defined by a fixed point
+ * system which allows the user to define the scale counter increment
+ * value at every level change of the oscillator driving the SYSTIME
+ * value. For both devices the TIMINCA:IV field defines this
+ * increment. On the X540 device, 31 bits are provided. However on the
+ * 82599 only provides 24 bits. The time unit is determined by the
+ * clock frequency of the oscillator in combination with the TIMINCA
+ * register. When these devices link at 10Gb the oscillator has a
+ * period of 6.4ns. In order to convert the scale counter into
+ * nanoseconds the cyclecounter and timecounter structures are
+ * used. The SYSTIME registers need to be converted to ns values by use
+ * of only a right shift (division by power of 2). The following math
+ * determines the largest incvalue that will fit into the available
+ * bits in the TIMINCA register.
+ *
+ * PeriodWidth: Number of bits to store the clock period
+ * MaxWidth: The maximum width value of the TIMINCA register
+ * Period: The clock period for the oscillator
+ * round(): discard the fractional portion of the calculation
+ *
+ * Period * [ 2 ^ ( MaxWidth - PeriodWidth ) ]
+ *
+ * For the X540, MaxWidth is 31 bits, and the base period is 6.4 ns
+ * For the 82599, MaxWidth is 24 bits, and the base period is 6.4 ns
+ *
+ * The period also changes based on the link speed:
+ * At 10Gb link or no link, the period remains the same.
+ * At 1Gb link, the period is multiplied by 10. (64ns)
+ * At 100Mb link, the period is multiplied by 100. (640ns)
+ *
+ * The calculated value allows us to right shift the SYSTIME register
+ * value in order to quickly convert it into a nanosecond clock,
+ * while allowing for the maximum possible adjustment value.
+ *
+ * These diagrams are only for the 10Gb link period

- To compile this driver as a module, choose M here. The only

- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where

- * 1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This
- * is not an exhaustive list.)
- * - The RBUF uses 64-byte mpackets.
- * - RX descriptors reside in SRAM, and have the following format:
- * struct rx_desc
- * {
- * // to uengine
- * u32 buf_phys_addr;
- * u32 buf_length;
- *
- * // from uengine
- * u32 channel;
- * u32 pkt_length;
- * };
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 0 is rx_pending.
- * - Scratch ring 1 is rx_done, and has status condition 'full'.
- * - The host triggers rx_done flush and rx_pending refill on seeing INTA.
- * - This code is run on all eight threads of the microengine it runs on.
- *
- * Local memory is used for per-channel RX state.

- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where
- * only one TBUF partition is used. This includes, for example,
- * 1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This
- * is not an exhaustive list.)
- * - The TBUF uses 64-byte mpackets.
- * - TX descriptors reside in SRAM, and have the following format:
- * struct tx_desc
- * {
- * // to uengine
- * u32 buf_phys_addr;
- * u32 pkt_length;
- * u32 channel;
- * };
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 2 is tx_pending.
- * - Scratch ring 3 is tx_done, and has status condition 'full'.
- * - This code is run on all eight threads of the microengine it runs on.

- * Technical Card Details
- *
- * All access to data is done with 16/8 bit transfers. The transfer
- * method really sucks. You can only read or write one location at a time.
- *
- * Also, the microcode for the card must be uploaded if the card does not have
- * the flashrom on board. This is a 28K bloat in the driver when compiled
- * as a module.
- *
- * Rx is very simple, status into a ring of descriptors, dma data transfer,
- * interrupts to tell us when a packet is received.
- *
- * Tx is a little more interesting. Similar scenario, descriptor and dma data
- * transfers, but we don't have to interrupt the card to tell it another packet
- * is ready for transmission, we are just doing simple memory writes, not io or mmio
- * writes. The card can be set up to simply poll on the next
- * descriptor pointer and when this value is non-zero will automatically download
- * the next packet. The card then interrupts us when the packet is done.

- * There are two ways of implementing rx on the 359 NIC, either
- * interrupt driven or polling. We are going to uses interrupts,
- * it is the easier way of doing things.
- *
- * The Rx works with a ring of Rx descriptors. At initialise time the ring
- * entries point to the next entry except for the last entry in the ring
- * which points to 0. The card is programmed with the location of the first
- * available descriptor and keeps reading the next_ptr until next_ptr is set
- * to 0. Hopefully with a ring size of 16 the card will never get to read a next_ptr
- * of 0. As the Rx interrupt is received we copy the frame up to the protocol layers
- * and then point the end of the ring to our current position and point our current
- * position to 0, therefore making the current position the last position on the ring.
- * The last position on the ring therefore loops continually loops around the rx ring.
- *
- * rx_ring_tail is the position on the ring to process next. (Think of a snake, the head
- * expands as the card adds new packets and we go around eating the tail processing the
- * packets.)
- *
- * Undoubtably it could be streamlined and improved upon, but at the moment it works
- * and the fast path through the routine is fine.
- *
- * adv_rx_ring could be inlined to increase performance, but its called a *lot* of times
- * in xl_rx so would increase the size of the function significantly.

-/* ibmtr.c: A shared-memory IBM Token Ring 16/4 driver for linux
- *
- * Written 1993 by Mark Swanson and Peter De Schrijver.
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * This device driver should work with Any IBM Token Ring Card that does
- * not use DMA.
- *
- * I used Donald Becker's (becker@scyld.com) device driver work
- * as a base for most of my initial work.
- *
- * Changes by Peter De Schrijver
- * (Peter.Deschrijver@linux.cc.kuleuven.ac.be) :
- *
- * + changed name to ibmtr.c in anticipation of other tr boards.
- * + changed reset code and adapter open code.
- * + added SAP open code.
- * + a first attempt to write interrupt, transmit and receive routines.
- *
- * Changes by David W. Morris (dwm@shell.portal.com) :
- * 941003 dwm: - Restructure tok_probe for multiple adapters, devices.
- * + Add comments, misc reorg for clarity.
- * + Flatten interrupt handler levels.
- *
- * Changes by Farzad Farid (farzy@zen.via.ecp.fr)
- * and Pascal Andre (andre@chimay.via.ecp.fr) (March 9 1995) :
- * + multi ring support clean up.
- * + RFC1042 compliance enhanced.
- *
- * Changes by Pascal Andre (andre@chimay.via.ecp.fr) (September 7 1995) :
- * + bug correction in tr_tx
- * + removed redundant information display
- * + some code reworking
- *
- * Changes by Michel Lespinasse (walken@via.ecp.fr),
- * Yann Doussot (doussot@via.ecp.fr) and Pascal Andre (andre@via.ecp.fr)
- * (February 18, 1996) :
- * + modified shared memory and mmio access port the driver to
- * alpha platform (structure access -> readb/writeb)
- *
- * Changes by Steve Kipisz (bungy@ibm.net or kipisz@vnet.ibm.com)
- * (January 18 1996):
- * + swapped WWOR and WWCR in ibmtr.h
- * + moved some init code from tok_probe into trdev_init. The
- * PCMCIA code can call trdev_init to complete initializing
- * the driver.
- * + added -DPCMCIA to support PCMCIA
- * + detecting PCMCIA Card Removal in interrupt handler. If
- * ISRP is FF, then a PCMCIA card has been removed
- * 10/2000 Burt needed a new method to avoid crashing the OS
- *
- * Changes by Paul Norton (pnorton@cts.com) :
- * + restructured the READ.LOG logic to prevent the transmit SRB
- * from being rudely overwritten before the transmit cycle is
- * complete. (August 15 1996)
- * + completed multiple adapter support. (November 20 1996)
- * + implemented csum_partial_copy in tr_rx and increased receive
- * buffer size and count. Minor fixes. (March 15, 1997)
- *
- * Changes by Christopher Turcksin <wabbit@rtfc.demon.co.uk>
- * + Now compiles ok as a module again.
- *
- * Changes by Paul Norton (pnorton@ieee.org) :
- * + moved the header manipulation code in tr_tx and tr_rx to
- * net/802/tr.c. (July 12 1997)
- * + add retry and timeout on open if cable disconnected. (May 5 1998)
- * + lifted 2000 byte mtu limit. now depends on shared-RAM size.
- * May 25 1998)
- * + can't allocate 2k recv buff at 8k shared-RAM. (20 October 1998)
- *
- * Changes by Joel Sloan (jjs@c-me.com) :
- * + disable verbose debug messages by default - to enable verbose
- * debugging, edit the IBMTR_DEBUG_MESSAGES define below
- *
- * Changes by Mike Phillips <phillim@amtrak.com> :
- * + Added extra #ifdef's to work with new PCMCIA Token Ring Code.
- * The PCMCIA code now just sets up the card so it can be recognized
- * by ibmtr_probe. Also checks allocated memory vs. on-board memory
- * for correct figure to use.
- *
- * Changes by Tim Hockin (thockin@isunix.it.ilstu.edu) :
- * + added spinlocks for SMP sanity (10 March 1999)
- *
- * Changes by Jochen Friedrich to enable RFC1469 Option 2 multicasting
- * i.e. using functional address C0 00 00 04 00 00 to transmit and
- * receive multicast packets.
- *
- * Changes by Mike Sullivan (based on original sram patch by Dave Grothe
- * to support windowing into on adapter shared ram.
- * i.e. Use LANAID to setup a PnP configuration with 16K RAM. Paging
- * will shift this 16K window over the entire available shared RAM.
- *
- * Changes by Peter De Schrijver (p2@mind.be) :
- * + fixed a problem with PCMCIA card removal
- *
- * Change by Mike Sullivan et al.:
- * + added turbo card support. No need to use lanaid to configure
- * the adapter into isa compatibility mode.
- *
- * Changes by Burt Silverman to allow the computer to behave nicely when
- * a cable is pulled or not in place, or a PCMCIA card is removed hot.

-/*======================================================================
-
- A PCMCIA token-ring driver for IBM-based cards
-
- This driver supports the IBM PCMCIA Token-Ring Card.
- Written by Steve Kipisz, kipisz@vnet.ibm.com or
- bungy@ibm.net
-
- Written 1995,1996.
-
- This code is based on pcnet_cs.c from David Hinds.
-
- V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
-
- Linux V2.2.x presented significant changes to the underlying
- ibmtr.c code. Mainly the code became a lot more organized and
- modular.
-
- This caused the old PCMCIA Token Ring driver to give up and go
- home early. Instead of just patching the old code to make it
- work, the PCMCIA code has been streamlined, updated and possibly
- improved.
-
- This code now only contains code required for the Card Services.
- All we do here is set the card up enough so that the real ibmtr.c
- driver can find it and work with it properly.
-
- i.e. We set up the io port, irq, mmio memory and shared ram
- memory. This enables ibmtr_probe in ibmtr.c to find the card and
- configure it as though it was a normal ISA and/or PnP card.
-
- CHANGES
-
- v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
- Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
-
- v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
- Updated to version 2.2.7 to match the first version of the kernel
- that the modification to ibmtr.c were incorporated into.
-
- v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
- Address translation feature of PCMCIA controller is usable so
- memory windows can be placed in High memory (meaning above
- 0xFFFFF.)

- *
- * 12/10/99 - Alpha Release 0.1.0
- * First release to the public
- * 03/03/00 - Merged to kernel, indented -kr -i8 -bri0, fixed some missing
- * malloc free checks, reviewed code. <alan@redhat.com>
- * 03/13/00 - Added spinlocks for smp
- * 03/08/01 - Added support for module_init() and module_exit()
- * 08/15/01 - Added ioctl() functionality for debugging, changed netif_*_queue
- * calls and other incorrectness - Kent Yoder <yoder1@us.ibm.com>
- * 11/05/01 - Restructured the interrupt function, added delays, reduced the
- * the number of TX descriptors to 1, which together can prevent
- * the card from locking up the box - <yoder1@us.ibm.com>
- * 09/27/02 - New PCI interface + bug fix. - <yoder1@us.ibm.com>
- * 11/13/02 - Removed free_irq calls which could cause a hang, added
- * netif_carrier_{on|off} - <yoder1@us.ibm.com>
- *
- * To Do:
- *
- *
- * If Problems do Occur
- * Most problems can be rectified by either closing and opening the interface
- * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- * if compiled into the kernel).

- * Handle interrupts generated by the card
- *
- * The MicroChannel Madge cards need slightly more handling
- * after an interrupt than other TMS380 cards do.
- *
- * First we must make sure it was this card that generated the
- * interrupt (since interrupt sharing is allowed). Then,
- * because we're using level-triggered interrupts (as is
- * standard on MCA), we must toggle the interrupt line
- * on the card in order to claim and acknowledge the interrupt.
- * Once that is done, the interrupt should be handlable in
- * the normal tms380tr_interrupt() routine.
- *
- * There's two ways we can check to see if the interrupt is ours,
- * both with their own disadvantages...
- *
- * 1) Read in the SIFSTS register from the TMS controller. This
- * is guaranteed to be accurate, however, there's a fairly
- * large performance penalty for doing so: the Madge chips
- * must request the register from the Eagle, the Eagle must
- * read them from its internal bus, and then take the route
- * back out again, for a 16bit read.
- *
- * 2) Use the MC_CONTROL_REG0_SINTR bit from the Madge ASICs.
- * The major disadvantage here is that the accuracy of the
- * bit is in question. However, it cuts out the extra read
- * cycles it takes to read the Eagle's SIF, as its only an
- * 8bit read, and theoretically the Madge bit is directly
- * connected to the interrupt latch coming out of the Eagle
- * hardware (that statement is not verified).
- *
- * I can't determine which of these methods has the best win. For now,
- * we make a compromise. Use the Madge way for the first interrupt,
- * which should be the fast-path, and then once we hit the first
- * interrupt, keep on trying using the SIF method until we've
- * exhausted all contiguous interrupts.

- * olympic.c (c) 1999 Peter De Schrijver All Rights Reserved
- * 1999/2000 Mike Phillips (mikep@linuxtr.net)
- *
- * Linux driver for IBM PCI tokenring cards based on the Pit/Pit-Phy/Olympic
- * chipset.
- *
- * Base Driver Skeleton:
- * Written 1993-94 by Donald Becker.
- *
- * Copyright 1993 United States Government as represented by the
- * Director, National Security Agency.
- *
- * Thanks to Erik De Cock, Adrian Bridgett and Frank Fiene for their
- * assistance and perserverance with the testing of this driver.
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * 4/27/99 - Alpha Release 0.1.0
- * First release to the public
- *
- * 6/8/99 - Official Release 0.2.0
- * Merged into the kernel code
- * 8/18/99 - Updated driver for 2.3.13 kernel to use new pci
- * resource. Driver also reports the card name returned by
- * the pci resource.
- * 1/11/00 - Added spinlocks for smp
- * 2/23/00 - Updated to dev_kfree_irq
- * 3/10/00 - Fixed FDX enable which triggered other bugs also
- * squashed.
- * 5/20/00 - Changes to handle Olympic on LinuxPPC. Endian changes.
- * The odd thing about the changes is that the fix for
- * endian issues with the big-endian data in the arb, asb...
- * was to always swab() the bytes, no matter what CPU.
- * That's because the read[wl]() functions always swap the
- * bytes on the way in on PPC.
- * Fixing the hardware descriptors was another matter,
- * because they weren't going through read[wl](), there all
- * the results had to be in memory in le32 values. kdaaker
- *
- * 12/23/00 - Added minimal Cardbus support (Thanks Donald).
- *
- * 03/09/01 - Add new pci api, dev_base_lock, general clean up.
- *
- * 03/27/01 - Add new dma pci (Thanks to Kyle Lucke) and alloc_trdev
- * Change proc_fs behaviour, now one entry per adapter.
- *
- * 04/09/01 - Couple of bug fixes to the dma unmaps and ejecting the
- * adapter when live does not take the system down with it.
- *
- * 06/02/01 - Clean up, copy skb for small packets
- *
- * 06/22/01 - Add EISR error handling routines
- *
- * 07/19/01 - Improve bad LAA reporting, strip out freemem
- * into a separate function, its called from 3
- * different places now.
- * 02/09/02 - Replaced sleep_on.
- * 03/01/02 - Replace access to several registers from 32 bit to
- * 16 bit. Fixes alignment errors on PPC 64 bit machines.
- * Thanks to Al Trautman for this one.
- * 03/10/02 - Fix BUG in arb_cmd. Bug was there all along but was
- * silently ignored until the error checking code
- * went into version 1.0.0
- * 06/04/02 - Add correct start up sequence for the cardbus adapters.
- * Required for strict compliance with pci power mgmt specs.
- * To Do:
- *
- * Wake on lan
- *
- * If Problems do Occur
- * Most problems can be rectified by either closing and opening the interface
- * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- * if compiled into the kernel).

- * skisa.c: A network driver for SK-NET TMS380-based ISA token ring cards.
- *
- * Based on tmspci written 1999 by Adam Fritzler
- *
- * Written 2000 by Jochen Friedrich
- * Dedicated to my girlfriend Steffi Bopp
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * This driver module supports the following cards:
- * - SysKonnect TR4/16(+) ISA (SK-4190)
- *
- * Maintainer(s):
- * AF Adam Fritzler
- * JF Jochen Friedrich jochen@scram.de
- *
- * Modification History:
- * 14-Jan-01 JF Created
- * 28-Oct-02 JF Fixed probe of card for static compilation.
- * Fixed module init to not make hotplug go wild.
- * 09-Nov-02 JF Fixed early bail out on out of memory
- * situations if multiple cards are found.
- * Cleaned up some unnecessary console SPAM.
- * 09-Dec-02 JF Fixed module reference counting.
- * 02-Jan-03 JF Renamed to skisa.c

-/*
- * tms380tr.c: A network driver library for Texas Instruments TMS380-based
- * Token Ring Adapters.
- *
- * Originally sktr.c: Written 1997 by Christoph Goos
- *
- * A fine result of the Linux Systems Network Architecture Project.
- * http://www.vanheusden.com/sna/
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * The following modules are currently available for card support:
- * - tmspci (Generic PCI card support)
- * - abyss (Madge PCI support)
- * - tmsisa (SysKonnect TR4/16 ISA)
- *
- * Sources:
- * - The hardware related parts of this driver are take from
- * the SysKonnect Token Ring driver for Windows NT.
- * - I used the IBM Token Ring driver 'ibmtr.c' as a base for this
- * driver, as well as the 'skeleton.c' driver by Donald Becker.
- * - Also various other drivers in the linux source tree were taken
- * as samples for some tasks.
- * - TI TMS380 Second-Generation Token Ring User's Guide
- * - TI datasheets for respective chips
- * - David Hein at Texas Instruments
- * - Various Madge employees
- *
- * Maintainer(s):
- * JS Jay Schulist jschlst@samba.org
- * CG Christoph Goos cgoos@syskonnect.de
- * AF Adam Fritzler
- * MLP Mike Phillips phillim@amtrak.com
- * JF Jochen Friedrich jochen@scram.de
- *
- * Modification History:
- * 29-Aug-97 CG Created
- * 04-Apr-98 CG Fixed problems caused by tok_timer_check
- * 10-Apr-98 CG Fixed lockups at cable disconnection
- * 27-May-98 JS Formated to Linux Kernel Format
- * 31-May-98 JS Hacked in PCI support
- * 16-Jun-98 JS Modulized for multiple cards with one driver
- * Sep-99 AF Renamed to tms380tr (supports more than SK's)
- * 23-Sep-99 AF Added Compaq and Thomas-Conrad PCI support
- * Fixed a bug causing double copies on PCI
- * Fixed for new multicast stuff (2.2/2.3)
- * 25-Sep-99 AF Uped TPL_NUM from 3 to 9
- * Removed extraneous 'No free TPL'
- * 22-Dec-99 AF Added Madge PCI Mk2 support and generalized
- * parts of the initilization procedure.
- * 30-Dec-99 AF Turned tms380tr into a library ala 8390.
- * Madge support is provided in the abyss module
- * Generic PCI support is in the tmspci module.
- * 30-Nov-00 JF Updated PCI code to support IO MMU via
- * pci_map_static(). Alpha uses this MMU for ISA
- * as well.
- * 14-Jan-01 JF Fix DMA on ifdown/ifup sequences. Some
- * cleanup.
- * 13-Jan-02 JF Add spinlock to fix race condition.
- * 09-Nov-02 JF Fixed printks to not SPAM the console during
- * normal operation.
- * 30-Dec-02 JF Removed incorrect __init from
- * tms380tr_init_card.
- * 22-Jul-05 JF Converted to dma-mapping.
- *
- * To do:
- * 1. Multi/Broadcast packet handling (this may have fixed itself)
- * 2. Write a sktrisa module that includes the old ISA support (done)
- * 3. Allow modules to load their own microcode
- * 4. Speed up the BUD process -- freezing the kernel for 3+sec is
- * quite unacceptable.
- * 5. Still a few remaining stalls when the cable is unplugged.

- * DOC: shared area - role and goal
- *
- * The shared area contains all the data exported by the upper layer to the
- * other layers. Since the bus and transport layer shouldn't dereference
- * iwl_priv, all the data needed by the upper layer and the transport / bus
- * layer must be here.
- * The shared area also holds pointer to all the other layers. This allows a
- * layer to call a function from another layer.
- *
- * NOTE: All the layers hold a pointer to the shared area which must be shrd.
- * A few macros assume that (_m)->shrd points to the shared area no matter
- * what _m is.
- *
- * gets notifications about enumeration, suspend, resume.
- * For the moment, the bus layer is not a linux kernel module as itself, and
- * the module_init function of the driver must call the bus specific
- * registration functions. These functions are listed at the end of this file.
- * For the moment, there is only one implementation of this interface: PCI-e.
- * This implementation is iwl-pci.c

+ The Configurable Composite Gadget supports multiple USB
+ functions: acm, mass storage, rndis and FunctionFS.
+ Each function can be configured and enabled/disabled
+ dynamically from userspace through a sysfs interface.
+
+ In order to compile this (either as a module or built-in),
+ "USB Gadget Drivers" and anything under it must not be
+ selected compiled-in in
+ Device Drivers->USB Support->USB Gadget Support.
+ However, you can say "M" there, if you do, the
+ Configurable Composite Gadget can be compiled "M" only
+ or not at all.

-Description:
- If known for a device, offset to be added to <type>[Y]_raw prior
- to scaling by <type>[Y]_scale in order to obtain value in the
- <type> units as specified in <type>[y]_raw documentation.
- Not present if the offset is always 0 or unknown. If Y or
- axis <x|y|z> is not present, then the offset applies to all
- in channels of <type>.
- May be writable if a variable offset can be applied on the
- device. Note that this is different to calibbias which
- is for devices (or drivers) that apply offsets to compensate
- for variation between different instances of the part, typically
- adjusted by using some hardware supported calibration procedure.
- Calibbias is applied internally, offset is applied in userspace
- to the _raw output.

- needs to be applied prior to masking out unused bits. Some
- devices put their data in the middle of the transferred elements
- with additional information on both sides. Note that some
- devices will have additional information in the unused bits
- so to get a clean value, the bits value must be used to mask
- the buffer output value appropriately. The storagebits value
- also specifies the data alignment. So s48/64>>2 will be a
- signed 48 bit integer stored in a 64 bit location aligned to
- a a64 bit boundary. To obtain the clean value, shift right 2
- and apply a mask to zero the top 16 bits of the result.
- For other storage combinations this attribute will be extended
- appropriately.

+ TODO
+ ====
+Introduction
+============
+
+These drivers add support for IndustryPack devices: carrier and mezzanine
+boards.
+
+The ipack driver is just an abstraction of the bus providing the common
+operations between the two kind of boards.
+
+TODO
+====
+
+TPCI-200
+--------
+
+* It receives the name of the mezzanine plugged in each slot by SYSFS.
+ No autodetection supported yet, because the mezzanine driver could not be
+ loaded at the time that the tpci200 driver loads.
+
+* It has a linked list with the tpci200 devices it is managing. Get rid of it
+ and use driver_for_each_device() instead.
+
+IP-OCTAL
+--------
+
+* It has a linked list which saves the devices it is currently
+ managing. It should use the driver_for_each_device() function. It is not there
+ due to the impossibility of using container_of macro to recover the
+ corresponding "struct ipoctal" because the attribute "struct ipack_device" is
+ a pointer. This code should be refactored.
+
+Ipack
+-----
+
+* The structures and API exported can be improved a lot. For example, the
+ way to unregistering mezzanine devices, doing the mezzanine driver a call to
+ remove_device() to notify the carrier driver, or the opposite with the call to
+ the ipack_driver_ops' remove() function could be improved.

-as a paramter - e.g. 'insmod ozwpan g_net_dev=go0') or can be bound after
+as a parameter - e.g. 'insmod ozwpan g_net_dev=go0') or can be bound after
loading using an ioctl call. See the ozappif.h file and the ioctls
OZ_IOCTL_ADD_BINDING and OZ_IOCTL_REMOVE_BINDING.

- * Francois-Rene Rideau <fare@tunes.org> 19971205
- * Made it to 2.1.71; now a facelift:
- * Put files under include/linux/byteorder/
- * Split swab from generic support.
- *
- * TODO:
- * = Regular kernel maintainers could also replace all these manual
- * byteswap macros that remain, disseminated among drivers,
- * after some grep or the sources...
- * = Linus might want to rename all these macros and files to fit his taste,
- * to fit his personal naming scheme.
- * = it seems that a few drivers would also appreciate
- * nybble swapping support...
- * = every architecture could add their byteswap macro in asm/byteorder.h
- * see how some architectures already do (i386, alpha, ppc, etc)
- * = cpu_to_beXX and beXX_to_cpu might some day need to be well
- * distinguished throughout the kernel. This is not the case currently,
- * since little endian, big endian, and pdp endian machines needn't it.

- depends on USB
- ---help---
- If you say Y here (and to "/proc file system support" in the "File
- systems" section, above), you will get a file /proc/bus/usb/devices
- which lists the devices currently connected to your USB bus or
- busses, and for every connected device a file named
- "/proc/bus/usb/xxx/yyy", where xxx is the bus number and yyy the
- device number; the latter files can be used by user space programs
- to talk directly to the device. These files are "virtual", meaning
- they are generated on the fly and not stored on the hard drive.
-
- You may need to mount the usbfs file system to see the files, use
- mount -t usbfs none /proc/bus/usb
-
- For the format of the various /proc/bus/usb/ files, please read
- <file:Documentation/usb/proc_usb_info.txt>.
-
- Modern Linux systems do not use this.
-
- Usbfs entries are files and not character devices; usbfs can't
- handle Access Control Lists (ACL) which are the default way to
- grant access to USB devices for untrusted users of a desktop
- system.
-
- The usbfs functionality is replaced by real device-nodes managed by
- udev. These nodes lived in /dev/bus/usb and are used by libusb.

-config USB_DEVICE_CLASS
- bool "USB device class-devices (DEPRECATED)"
- depends on USB
- default y
- ---help---
- Userspace access to USB devices is granted by device-nodes exported
- directly from the usbdev in sysfs. Old versions of the driver
- core and udev needed additional class devices to export device nodes.
-
- These additional devices are difficult to handle in userspace, if
- information about USB interfaces must be available. One device
- contains the device node, the other device contains the interface
- data. Both devices are at the same level in sysfs (siblings) and one
- can't access the other. The device node created directly by the
- usb device is the parent device of the interface and therefore
- easily accessible from the interface event.
-
- This option provides backward compatibility for libusb device
- nodes (lsusb) when usbfs is not used, and the following udev rule
- doesn't exist:
- SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \

- * Description: MIPS USB IP core family device controller
- * Currently it only supports IP part number CI13412
- *
- * This driver is composed of several blocks:
- * - HW: hardware interface
- * - DBG: debug facilities (optional)
- * - UTIL: utilities
- * - ISR: interrupts handling
- * - ENDPT: endpoint operations (Gadget API)
- * - GADGET: gadget operations (Gadget API)
- * - BUS: bus glue code, bus abstraction layer
- *
- * Compile Options
- * - CONFIG_USB_GADGET_DEBUG_FILES: enable debug facilities
- * - STALL_IN: non-empty bulk-in pipes cannot be halted
- * if defined mass storage compliance succeeds but with warnings
- * => case 4: Hi > Dn
- * => case 5: Hi > Di
- * => case 8: Hi <> Do
- * if undefined usbtest 13 fails
- * - TRACE: enable function tracing (depends on DEBUG)
- *
- * Main Features
- * - Chapter 9 & Mass Storage Compliance with Gadget File Storage
- * - Chapter 9 Compliance with Gadget Zero (STALL_IN undefined)
- * - Normal & LPM support
- *
- * USBTEST Report
- * - OK: 0-12, 13 (STALL_IN defined) & 14
- * - Not Supported: 15 & 16 (ISO)
- *
- * TODO List
- * - OTG
- * - Isochronous & Interrupt Traffic
- * - Handle requests which spawns into several TDs
- * - GET_STATUS(device) - always reports 0
- * - Gadget API (majority of optional features)
- * - Suspend & Remote Wakeup

/**
+ * DOC: HW queue control
+ *
+ * Before HW queue control was introduced, mac80211 only had a single static
+ * assignment of per-interface AC software queues to hardware queues. This
+ * was problematic for a few reasons:
+ * 1) off-channel transmissions might get stuck behind other frames
+ * 2) multiple virtual interfaces couldn't be handled correctly
+ * 3) after-DTIM frames could get stuck behind other frames
+ *
+ * To solve this, hardware typically uses multiple different queues for all
+ * the different usages, and this needs to be propagated into mac80211 so it
+ * won't have the same problem with the software queues.
+ *
+ * Therefore, mac80211 now offers the %IEEE80211_HW_QUEUE_CONTROL capability
+ * flag that tells it that the driver implements its own queue control. To do
+ * so, the driver will set up the various queues in each &struct ieee80211_vif
+ * and the offchannel queue in &struct ieee80211_hw. In response, mac80211 will
+ * use those queue IDs in the hw_queue field of &struct ieee80211_tx_info and
+ * if necessary will queue the frame on the right software queue that mirrors
+ * the hardware queue.
+ * Additionally, the driver has to then use these HW queue IDs for the queue
+ * management functions (ieee80211_stop_queue() et al.)
+ *
+ * The driver is free to set up the queue mappings as needed, multiple virtual
+ * interfaces may map to the same hardware queues if needed. The setup has to
+ * happen during add_interface or change_interface callbacks. For example, a
+ * driver supporting station+station and station+AP modes might decide to have
+ * 10 hardware queues to handle different scenarios:
+ *
+ * 4 AC HW queues for 1st vif: 0, 1, 2, 3
+ * 4 AC HW queues for 2nd vif: 4, 5, 6, 7
+ * after-DTIM queue for AP: 8
+ * off-channel queue: 9
+ *
+ * It would then set up the hardware like this:
+ * hw.offchannel_tx_hw_queue = 9
+ *
+ * and the first virtual interface that is added as follows:
+ * vif.hw_queue[IEEE80211_AC_VO] = 0
+ * vif.hw_queue[IEEE80211_AC_VI] = 1
+ * vif.hw_queue[IEEE80211_AC_BE] = 2
+ * vif.hw_queue[IEEE80211_AC_BK] = 3
+ * vif.cab_queue = 8 // if AP mode, otherwise %IEEE80211_INVAL_HW_QUEUE
+ * and the second virtual interface with 4-7.
+ *
+ * If queue 6 gets full, for example, mac80211 would only stop the second
+ * virtual interface's BE queue since virtual interface queues are per AC.
+ *
+ * Note that the vif.cab_queue value should be set to %IEEE80211_INVAL_HW_QUEUE
+ * whenever the queue is not used (i.e. the interface is not in AP mode) if the
+ * queue could potentially be shared since mac80211 will look at cab_queue when
+ * a queue is stopped/woken even if the interface is not in AP mode.

+/*
+ * The printk log buffer consists of a chain of concatenated variable
+ * length records. Every record starts with a record header, containing
+ * the overall length of the record.
+ *
+ * The heads to the first and last entry in the buffer, as well as the
+ * sequence numbers of these both entries are maintained when messages
+ * are stored..
+ *
+ * If the heads indicate available messages, the length in the header
+ * tells the start next message. A length == 0 for the next message
+ * indicates a wrap-around to the beginning of the buffer.
+ *
+ * Every record carries the monotonic timestamp in microseconds, as well as
+ * the standard userspace syslog level and syslog facility. The usual
+ * kernel messages use LOG_KERN; userspace-injected messages always carry
+ * a matching syslog facility, by default LOG_USER. The origin of every
+ * message can be reliably determined that way.
+ *
+ * The human readable log message directly follows the message header. The
+ * length of the message text is stored in the header, the stored message
+ * is not terminated.
+ *
+ * Optionally, a message can carry a dictionary of properties (key/value pairs),
+ * to provide userspace with a machine-readable message context.
+ *
+ * Examples for well-defined, commonly used property names are:
+ * DEVICE=b12:8 device identifier
+ * b12:8 block dev_t
+ * c127:3 char dev_t
+ * n8 netdev ifindex
+ * +sound:card0 subsystem:devname
+ * SUBSYSTEM=pci driver-core subsystem name
+ *
+ * Valid characters in property names are [a-zA-Z0-9.-_]. The plain text value
+ * follows directly after a '=' character. Every property is terminated by
+ * a '\0' character. The last property is not terminated.
+ *
+ * Example of a message structure:
+ * 0000 ff 8f 00 00 00 00 00 00 monotonic time in nsec
+ * 0008 34 00 record is 52 bytes long
+ * 000a 0b 00 text is 11 bytes long
+ * 000c 1f 00 dictionary is 23 bytes long
+ * 000e 03 00 LOG_KERN (facility) LOG_ERR (level)
+ * 0010 69 74 27 73 20 61 20 6c "it's a l"
+ * 69 6e 65 "ine"
+ * 001b 44 45 56 49 43 "DEVIC"
+ * 45 3d 62 38 3a 32 00 44 "E=b8:2\0D"
+ * 52 49 56 45 52 3d 62 75 "RIVER=bu"
+ * 67 "g"
+ * 0032 00 00 00 padding to next message header
+ *
+ * The 'struct log' buffer header must never be directly exported to
+ * userspace, it is a kernel-private implementation detail that might
+ * need to be changed in the future, when the requirements change.
+ *
+ * /dev/kmsg exports the structured data in the following line format:
+ * "level,sequnum,timestamp;<message text>\n"
+ *
+ * The optional key/value pairs are attached as continuation lines starting
+ * with a space character and terminated by a newline. All possible
+ * non-prinatable characters are escaped in the "\xff" notation.
+ *
+ * Users of the export format should ignore possible additional values
+ * separated by ',', and find the message after the ';' character.

- Econet is a fairly old and slow networking protocol mainly used by
- Acorn computers to access file and print servers. It uses native
- Econet network cards. AUN is an implementation of the higher level
- parts of Econet that runs over ordinary Ethernet connections, on
- top of the UDP packet protocol, which in turn runs on top of the
- Internet protocol IP.
-
- If you say Y here, you can choose with the next two options whether
- to send Econet/AUN traffic over a UDP Ethernet connection or over
- a native Econet network card.
-
- To compile this driver as a module, choose M here: the module
- will be called econet.

+ This option adds the "HMARK" target.
+
+ The target allows you to create rules in the "raw" and "mangle" tables
+ which set the skbuff mark by means of hash calculation within a given
+ range. The nfmark can influence the routing method (see "Use netfilter
+ MARK value as routing key") and can also be used by other subsystems to
+ change their behaviour.
+
+ To compile it as a module, choose M here. If unsure, say N.

- This option provides support for retaining authentication tokens and

-
- It also includes provision of methods by which such keys might be
- associated with a process so that network filesystems, encryption
- support and the like can find them.
-
- Furthermore, a special type of key is available that acts as keyring:
- a searchable sequence of keys. Each process is equipped with access
- to five standard keyrings: UID-specific, GID-specific, session,
- process and thread.

- which are encrypted/decrypted with a 'master' symmetric key. The
- 'master' key can be either a trusted-key or user-key type.

- This option turns on support for the /proc/keys file - through which
- can be listed all the keys on the system that are viewable by the
- reading process.
-
- The only keys included in the list are those that grant View
- permission to the reading process whether or not it possesses them.
- Note that LSM security checks are still performed, and may further
- filter out keys that the current process is not authorised to view.
-
- Only key attributes are listed here; key payloads are not included in

+ This option provides support for retaining authentication tokens and
+ access keys in the kernel.
+
+ It also includes provision of methods by which such keys might be
+ associated with a process so that network filesystems, encryption
+ support and the like can find them.
+
+ Furthermore, a special type of key is available that acts as keyring:
+ a searchable sequence of keys. Each process is equipped with access
+ to five standard keyrings: UID-specific, GID-specific, session,
+ process and thread.

+ help
+ This option provides support for creating, sealing, and unsealing
+ keys in the kernel. Trusted keys are random number symmetric keys,
+ generated and RSA-sealed by the TPM. The TPM only unseals the keys,
+ if the boot PCRs and other criteria match. Userspace will only ever
+ see encrypted blobs.
+
+ If you are unsure as to whether this is required, answer N.

+ help
+ This option provides support for create/encrypting/decrypting keys
+ in the kernel. Encrypted keys are kernel generated random numbers,
+ which are encrypted/decrypted with a 'master' symmetric key. The
+ 'master' key can be either a trusted-key or user-key type.
+ Userspace only ever sees/stores encrypted blobs.
+
+ If you are unsure as to whether this is required, answer N.
+
+config KEYS_DEBUG_PROC_KEYS
+ bool "Enable the /proc/keys file by which keys may be viewed"
+ depends on KEYS
+ help
+ This option turns on support for the /proc/keys file - through which
+ can be listed all the keys on the system that are viewable by the
+ reading process.
+
+ The only keys included in the list are those that grant View
+ permission to the reading process whether or not it possesses them.
+ Note that LSM security checks are still performed, and may further
+ filter out keys that the current process is not authorised to view.
+
+ Only key attributes are listed here; key payloads are not included in
+ the resulting table.

+This directory contains example configs to use ktest for various tasks.

+
+snowball.conf - An example config that was used to demo ktest.pl against
+ a snowball ARM board.
+
+include/ - The include directory holds default configs that can be
+ included into other configs. This is a real use example that shows how
+ to reuse configs for various machines or set ups. The files here
+ are included by other config files, where the other config files define

+# This file has some examples for creating a MIN_CONFIG.
+# (A .config file that is the minimum for a machine to boot, or
+# to boot and make a network connection.)
+#
+# A MIN_CONFIG is very useful as it is the minimum configuration
+# needed to boot a given machine. You can debug someone else's
+# .config by only setting the configs in your MIN_CONFIG. The closer
+# your MIN_CONFIG is to the true minimum set of configs needed to
+# boot your machine, the closer the config you test with will be
+# to the users config that had the failure.
+#
+# The make_min_config test allows you to create a MIN_CONFIG that
+# is truly the minimum set of configs needed to boot a box.
+#
+# In this example, the final config will reside in
+# ${CONFIG_DIR}/config-new-min and ${CONFIG_DIR}/config-new-min-net.
+# Just move one to the location you have set for MIN_CONFIG.
+#
+# The first test creates a MIN_CONFIG that will be the minimum
+# configuration to boot ${MACHINE} and be able to ssh to it.
+#
+# The second test creates a MIN_CONFIG that will only boot
+# the target and most likely will not let you ssh to it. (Notice
+# how the second test uses the first test's result to continue with.
+# This is because the second test config is a subset of the first).
+#
+# The ${CONFIG_DIR}/config-skip (and -net) will hold the configs
+# that ktest.pl found would not boot the target without them set.
+# The config-new-min holds configs that ktest.pl could not test
+# directly because another config that was needed to boot the box
+# selected them. Sometimes it is possible that this file will hold
+# the true minimum configuration. You can test to see if this is
+# the case by running the boot test with BOOT_TYPE = allnoconfig and
+# setting setting the MIN_CONFIG to ${CONFIG_DIR}/config-skip. If the
+# machine still boots, then you can use the config-skip as your MIN_CONFIG.
+#
+# These tests can run for several hours (and perhaps days).
+# It's OK to kill the test with a Ctrl^C. By restarting without
+# modifying this config, ktest.pl will notice that the config-new-min(-net)
+# exists, and will use that instead as the starting point.
+# The USE_OUTPUT_MIN_CONFIG is set to 1 to keep ktest.pl from asking
