+Description:
+ This directory exposes interfaces for interactive with
+ EFI variables. For more information on EFI variables,
+ see 'Variable Services' in the UEFI specification
+ (section 7.2 in specification version 2.3 Errata D).
+
+ In summary, EFI variables are named, and are classified
+ into separate namespaces through the use of a vendor
+ GUID. They also have an arbitrary binary value
+ associated with them.
+
+ The efivars module enumerates these variables and
+ creates a separate directory for each one found. Each
+ directory has a name of the form "<key>-<vendor guid>"
+ and contains the following files:
+
+ attributes: A read-only text file enumerating the
+ EFI variable flags. Potential values
+ include:
+
+ EFI_VARIABLE_NON_VOLATILE
+ EFI_VARIABLE_BOOTSERVICE_ACCESS
+ EFI_VARIABLE_RUNTIME_ACCESS
+ EFI_VARIABLE_HARDWARE_ERROR_RECORD
+ EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS
+
+ See the EFI documentation for an
+ explanation of each of these variables.
+
+ data: A read-only binary file that can be read
+ to attain the value of the EFI variable
+
+ guid: The vendor GUID of the variable. This
+ should always match the GUID in the
+ variable's name.
+
+ raw_var: A binary file that can be read to obtain
+ a structure that contains everything
+ there is to know about the variable.
+ For structure definition see "struct
+ efi_variable" in the kernel sources.
+
+ This file can also be written to in
+ order to update the value of a variable.
+ For this to work however, all fields of
+ the "struct efi_variable" passed must
+ match byte for byte with the structure
+ read out of the file, save for the value
+ portion.
+
+ **Note** the efi_variable structure
+ read/written with this file contains a
+ 'long' type that may change widths
+ depending on your underlying
+ architecture.
+
+ size: As ASCII representation of the size of
+ the variable's value.
+
+
+ In addition, two other magic binary files are provided
+ in the top-level directory and are used for adding and
+ removing variables:
+
+ new_var: Takes a "struct efi_variable" and
+ instructs the EFI firmware to create a
+ new variable.
+
+ del_var: Takes a "struct efi_variable" and
+ instructs the EFI firmware to remove any
+ variable that has a matching vendor GUID
+ and variable key name.

+Description:
+ Many machines' firmware (x86 and ia64) export DMI /
+ SMBIOS tables to the operating system. Getting at this
+ information is often valuable to userland, especially in
+ cases where there are OEM extensions used.
+
+ The kernel itself does not rely on the majority of the
+ information in these tables being correct. It equally
+ cannot ensure that the data as exported to userland is
+ without error either.
+
+ DMI is structured as a large table of entries, where
+ each entry has a common header indicating the type and
+ length of the entry, as well as 'handle' that is
+ supposed to be unique amongst all entries.
+
+ Some entries are required by the specification, but many
+ others are optional. In general though, users should
+ never expect to find a specific entry type on their
+ system unless they know for certain what their firmware
+ is doing. Machine to machine will vary.
+
+ Multiple entries of the same type are allowed. In order
+ to handle these duplicate entry types, each entry is
+ assigned by the operating system an 'instance', which is
+ derived from an entry type's ordinal position. That is
+ to say, if there are 'N' multiple entries with the same type
+ 'T' in the DMI tables (adjacent or spread apart, it
+ doesn't matter), they will be represented in sysfs as
+ entries "T-0" through "T-(N-1)":
+
+ Example entry directories:
+
+ /sys/firmware/dmi/entries/17-0
+ /sys/firmware/dmi/entries/17-1
+ /sys/firmware/dmi/entries/17-2
+ /sys/firmware/dmi/entries/17-3
+ ...
+
+ Instance numbers are used in lieu of the firmware
+ assigned entry handles as the kernel itself makes no
+ guarantees that handles as exported are unique, and
+ there are likely firmware images that get this wrong in
+ the wild.
+
+ Each DMI entry in sysfs has the common header values
+ exported as attributes:
+
+ handle : The 16bit 'handle' that is assigned to this
+ entry by the firmware. This handle may be
+ referred to by other entries.
+ length : The length of the entry, as presented in the
+ entry itself. Note that this is _not the
+ total count of bytes associated with the
+ entry_. This value represents the length of
+ the "formatted" portion of the entry. This
+ "formatted" region is sometimes followed by
+ the "unformatted" region composed of nul
+ terminated strings, with termination signalled
+ by a two nul characters in series.
+ raw : The raw bytes of the entry. This includes the
+ "formatted" portion of the entry, the
+ "unformatted" strings portion of the entry,
+ and the two terminating nul characters.
+ type : The type of the entry. This value is the same
+ as found in the directory name. It indicates
+ how the rest of the entry should be
+ interpreted.
+ instance: The instance ordinal of the entry for the
+ given type. This value is the same as found
+ in the parent directory name.
+ position: The position of the entry within the entirety
+ of the entirety.
+
+ === Entry Specialization ===
+
+ Some entry types may have other information available in
+ sysfs.
+
+ --- Type 15 - System Event Log ---
+
+ This entry allows the firmware to export a log of
+ events the system has taken. This information is
+ typically backed by nvram, but the implementation
+ details are abstracted by this table. This entries data
+ is exported in the directory:
+
+ /sys/firmware/dmi/entries/15-0/system_event_log
+
+ and has the following attributes (documented in the
+ SMBIOS / DMI specification under "System Event Log (Type 15)":
+
+ area_length
+ header_start_offset
+ data_start_offset
+ access_method
+ status
+ change_token
+ access_method_address
+ header_format
+ per_log_type_descriptor_length
+ type_descriptors_supported_count
+
+ As well, the kernel exports the binary attribute:
+
+ raw_event_log : The raw binary bits of the event log
+ as described by the DMI entry.

+CE4100 I2C
+----------
+
+CE4100 has one PCI device which is described as the I2C-Controller. This
+PCI device has three PCI-bars, each bar contains a complete I2C
+controller. So we have a total of three independent I2C-Controllers
+which share only an interrupt line.
+The driver is probed via the PCI-ID and is gathering the information of
+attached devices from the devices tree.
+Grant Likely recommended to use the ranges property to map the PCI-Bar
+number to its physical address and to use this to find the child nodes
+of the specific I2C controller. This were his exact words:
+
+ Here's where the magic happens. Each entry in
+ ranges describes how the parent pci address space
+ (middle group of 3) is translated to the local
+ address space (first group of 2) and the size of
+ each range (last cell). In this particular case,
+ the first cell of the local address is chosen to be
+ 1:1 mapped to the BARs, and the second is the
+ offset from be base of the BAR (which would be
+ non-zero if you had 2 or more devices mapped off
+ the same BAR)
+
+ ranges allows the address mapping to be described
+ in a way that the OS can interpret without
+ requiring custom device driver code.
+

+CE4100 Device Tree Bindings
+---------------------------
+
+The CE4100 SoC uses for in core peripherals the following compatible
+format: <vendor>,<chip>-<device>.
+Many of the "generic" devices like HPET or IO APIC have the ce4100
+name in their compatible property because they first appeared in this
+SoC.
+
+The CPU node
+------------
+ cpu@0 {
+ device_type = "cpu";
+ compatible = "intel,ce4100";
+ reg = <0>;
+ lapic = <&lapic0>;
+ };
+
+The reg property describes the CPU number. The lapic property points to
+the local APIC timer.
+
+The SoC node
+------------
+
+This node describes the in-core peripherals. Required property:
+ compatible = "intel,ce4100-cp";
+
+The PCI node
+------------
+This node describes the PCI bus on the SoC. Its property should be
+ compatible = "intel,ce4100-pci", "pci";
+
+If the OS is using the IO-APIC for interrupt routing then the reported
+interrupt numbers for devices is no longer true. In order to obtain the
+correct interrupt number, the child node which represents the device has
+to contain the interrupt property. Besides the interrupt property it has
+to contain at least the reg property containing the PCI bus address and
+compatible property according to "PCI Bus Binding Revision 2.1".

+TRANSITIVITY
+------------
+
+Transitivity is a deeply intuitive notion about ordering that is not
+always provided by real computer systems. The following example
+demonstrates transitivity (also called "cumulativity"):
+
+ CPU 1 CPU 2 CPU 3
+ ======================= ======================= =======================
+ { X = 0, Y = 0 }
+ STORE X=1 LOAD X STORE Y=1
+ <general barrier> <general barrier>
+ LOAD Y LOAD X
+
+Suppose that CPU 2's load from X returns 1 and its load from Y returns 0.
+This indicates that CPU 2's load from X in some sense follows CPU 1's
+store to X and that CPU 2's load from Y in some sense preceded CPU 3's
+store to Y. The question is then "Can CPU 3's load from X return 0?"
+
+Because CPU 2's load from X in some sense came after CPU 1's store, it
+is natural to expect that CPU 3's load from X must therefore return 1.
+This expectation is an example of transitivity: if a load executing on
+CPU A follows a load from the same variable executing on CPU B, then
+CPU A's load must either return the same value that CPU B's load did,
+or must return some later value.
+
+In the Linux kernel, use of general memory barriers guarantees
+transitivity. Therefore, in the above example, if CPU 2's load from X
+returns 1 and its load from Y returns 0, then CPU 3's load from X must
+also return 1.
+
+However, transitivity is -not- guaranteed for read or write barriers.
+For example, suppose that CPU 2's general barrier in the above example
+is changed to a read barrier as shown below:
+
+ CPU 1 CPU 2 CPU 3
+ ======================= ======================= =======================
+ { X = 0, Y = 0 }
+ STORE X=1 LOAD X STORE Y=1
+ <read barrier> <general barrier>
+ LOAD Y LOAD X
+
+This substitution destroys transitivity: in this example, it is perfectly
+legal for CPU 2's load from X to return 1, its load from Y to return 0,
+and CPU 3's load from X to return 0.
+
+The key point is that although CPU 2's read barrier orders its pair
+of loads, it does not guarantee to order CPU 1's store. Therefore, if
+this example runs on a system where CPUs 1 and 2 share a store buffer
+or a level of cache, CPU 2 might have early access to CPU 1's writes.
+General barriers are therefore required to ensure that all CPUs agree
+on the combined order of CPU 1's and CPU 2's accesses.
+
+To reiterate, if your code requires transitivity, use general barriers
+throughout.

+Device Power Domains
+--------------------
+Sometimes devices share reference clocks or other power resources. In those
+cases it generally is not possible to put devices into low-power states
+individually. Instead, a set of devices sharing a power resource can be put
+into a low-power state together at the same time by turning off the shared
+power resource. Of course, they also need to be put into the full-power state
+together, by turning the shared power resource on. A set of devices with this
+property is often referred to as a power domain.
+
+Support for power domains is provided through the pwr_domain field of struct
+device. This field is a pointer to an object of type struct dev_power_domain,
+defined in include/linux/pm.h, providing a set of power management callbacks
+analogous to the subsystem-level and device driver callbacks that are executed
+for the given device during all power transitions, in addition to the respective
+subsystem-level callbacks. Specifically, the power domain "suspend" callbacks
+(i.e. ->runtime_suspend(), ->suspend(), ->freeze(), ->poweroff(), etc.) are
+executed after the analogous subsystem-level callbacks, while the power domain
+"resume" callbacks (i.e. ->runtime_resume(), ->resume(), ->thaw(), ->restore,
+etc.) are executed before the analogous subsystem-level callbacks. Error codes
+returned by the "suspend" and "resume" power domain callbacks are ignored.
+
+Power domain ->runtime_idle() callback is executed before the subsystem-level
+->runtime_idle() callback and the result returned by it is not ignored. Namely,
+if it returns error code, the subsystem-level ->runtime_idle() callback will not
+be called and the helper function rpm_idle() executing it will return error
+code. This mechanism is intended to help platforms where saving device state
+is a time consuming operation and should only be carried out if all devices
+in the power domain are idle, before turning off the shared power resource(s).
+Namely, the power domain ->runtime_idle() callback may return error code until
+the pm_runtime_idle() helper (or its asychronous version) has been called for
+all devices in the power domain (it is recommended that the returned error code
+be -EBUSY in those cases), preventing the subsystem-level ->runtime_idle()
+callback from being run prematurely.
+
+The support for device power domains is only relevant to platforms needing to
+use the same subsystem-level (e.g. platform bus type) and device driver power
+management callbacks in many different power domain configurations and wanting
+to avoid incorporating the support for power domains into the subsystem-level
+callbacks. The other platforms need not implement it or take it into account
+in any way.

+n_gsm.c GSM 0710 tty multiplexor HOWTO
+===================================================
+
+This line discipline implements the GSM 07.10 multiplexing protocol
+detailed in the following 3GPP document :
+http://www.3gpp.org/ftp/Specs/archive/07_series/07.10/0710-720.zip
+
+This document give some hints on how to use this driver with GPRS and 3G
+modems connected to a physical serial port.
+
+How to use it
+-------------
+1- initialize the modem in 0710 mux mode (usually AT+CMUX= command) through
+its serial port. Depending on the modem used, you can pass more or less
+parameters to this command,
+2- switch the serial line to using the n_gsm line discipline by using
+TIOCSETD ioctl,
+3- configure the mux using GSMIOC_GETCONF / GSMIOC_SETCONF ioctl,
+
+Major parts of the initialization program :
+(a good starting point is util-linux-ng/sys-utils/ldattach.c)
+#include <linux/gsmmux.h>
+#define N_GSM0710 21 /* GSM 0710 Mux */
+#define DEFAULT_SPEED B115200
+#define SERIAL_PORT /dev/ttyS0
+
+ int ldisc = N_GSM0710;
+ struct gsm_config c;
+ struct termios configuration;
+
+ /* open the serial port connected to the modem */
+ fd = open(SERIAL_PORT, O_RDWR | O_NOCTTY | O_NDELAY);
+
+ /* configure the serial port : speed, flow control ... */
+
+ /* send the AT commands to switch the modem to CMUX mode
+ and check that it's succesful (should return OK) */
+ write(fd, "AT+CMUX=0\r", 10);
+
+ /* experience showed that some modems need some time before
+ being able to answer to the first MUX packet so a delay
+ may be needed here in some case */
+ sleep(3);
+
+ /* use n_gsm line discipline */
+ ioctl(fd, TIOCSETD, &ldisc);
+
+ /* get n_gsm configuration */
+ ioctl(fd, GSMIOC_GETCONF, &c);
+ /* we are initiator and need encoding 0 (basic) */
+ c.initiator = 1;
+ c.encapsulation = 0;
+ /* our modem defaults to a maximum size of 127 bytes */
+ c.mru = 127;
+ c.mtu = 127;
+ /* set the new configuration */
+ ioctl(fd, GSMIOC_SETCONF, &c);
+
+ /* and wait for ever to keep the line discipline enabled */
+ daemon(0,0);
+ pause();
+
+4- create the devices corresponding to the "virtual" serial ports (take care,
+each modem has its configuration and some DLC have dedicated functions,
+for example GPS), starting with minor 1 (DLC0 is reserved for the management
+of the mux)
+
+MAJOR=`cat /proc/devices |grep gsmtty | awk '{print $1}`
+for i in `seq 1 4`; do
+ mknod /dev/ttygsm$i c $MAJOR $i
+done
+
+5- use these devices as plain serial ports.
+for example, it's possible :
+- and to use gnokii to send / receive SMS on ttygsm1
+- to use ppp to establish a datalink on ttygsm2
+
+6- first close all virtual ports before closing the physical port.
+
+Additional Documentation

+More practical details on the protocol and how it's supported by industrial
+modems can be found in the following documents :

+全团队有可能会从部分的维护者那里引进额外的帮助来了解并且修复安全漏洞。
+当遇到任何漏洞，所能提供的信息越多就越能诊断和修复。如果你不清楚什么
+是有帮助的信息，那就请重温一下REPORTING-BUGS文件中的概述过程。任
+何攻击性的代码都是非常有用的，未经报告者的同意不会被取消，除非它已经
+被公布于众。
+
+2) 公开
+
+Linux内核安全团队的宗旨就是和漏洞提交者一起处理漏洞的解决方案直
+到公开。我们喜欢尽快地完全公开漏洞。当一个漏洞或者修复还没有被完全地理
+解，解决方案没有通过测试或者供应商协调，可以合理地延迟公开。然而，我们
+期望这些延迟尽可能的短些，是可数的几天，而不是几个星期或者几个月。公开
+日期是通过安全团队和漏洞提供者以及供应商洽谈后的结果。公开时间表是从很
+短（特殊的，它已经被公众所知道）到几个星期。作为一个基本的默认政策，我
+们所期望通知公众的日期是7天的安排。
+
+3) 保密协议
+
+Linux内核安全团队不是一个正式的团体，因此不能加入任何的保密协议。

+以下为正文
+---------------------------------------------------------------------
+这个文件是有关当前使用的魔术值注册表。当你给一个结构添加了一个魔术值，你也应该把这个魔术值添加到这个文件，因为我们最好把用于各种结构的魔术值统一起来。
+
+使用魔术值来保护内核数据结构是一个非常好的主意。这就允许你在运行期检查(a)一个结构是否已经被攻击，或者(b)你已经给一个例行程序通过了一个错误的结构。后一种情况特别地有用---特别是当你通过一个空指针指向结构体的时候。tty源码，例如，经常通过特定驱动使用这种方法并且反复地排列特定方面的结构。
+
+使用魔术值的方法是在结构的开始处声明的，如下：
+
+struct tty_ldisc {
+ int magic;
+ ...
+};
+
+当你以后给内核添加增强功能的时候，请遵守这条规则！这样就会节省数不清的调试时间，特别是一些古怪的情况，例如，数组超出范围并且重新写了超出部分。遵守这个规则，这些情况可以被快速地，安全地避免。

+请注意，在声音记忆管理中仍然有每一些被定义的驱动魔术值。查看include/sound/sndmagic.h来获取他们完整的列表信息。很多OSS声音驱动拥有自己从声卡PCI ID构建的魔术值-他们也没有被列在这里。
+
+IrDA子系统也使用了大量的自己的魔术值，查看include/net/irda/irda.h来获取他们完整的信息。
+
+HFS是另外一个比较大的使用魔术值的文件系统-你可以在fs/hfs/hfs.h中找到他们。

+ * Locking:
+ *
+ * Each struct clk has a spinlock.
+ *
+ * To avoid AB-BA locking problems, locks must always be traversed from child
+ * clock to parent clock. For example, when enabling a clock, the clock's lock
+ * is taken, and then clk_enable is called on the parent, which take's the
+ * parent clock's lock. There is one exceptions to this ordering: When dumping
+ * the clock tree through debugfs. In this case, clk_lock_all is called,
+ * which attemps to iterate through the entire list of clocks and take every
+ * clock lock. If any call to spin_trylock fails, all locked clocks are
+ * unlocked, and the process is retried. When all the locks are held,
+ * the only clock operation that can be called is clk_get_rate_all_locked.
+ *
+ * Within a single clock, no clock operation can call another clock operation
+ * on itself, except for clk_get_rate_locked and clk_set_rate_locked. Any
+ * clock operation can call any other clock operation on any of it's possible
+ * parents.
+ *
+ * An additional mutex, clock_list_lock, is used to protect the list of all
+ * clocks.
+ *
+ * The clock operations must lock internally to protect against
+ * read-modify-write on registers that are shared by multiple clocks

* P2M_PER_PAGE depends on the architecture, as a mfn is always
* unsigned long (8 bytes on 64-bit, 4 bytes on 32), leading to
* 512 and 1024 entries respectively.
+ *
+ * In short, these structures contain the Machine Frame Number (MFN) of the PFN.
+ *
+ * However not all entries are filled with MFNs. Specifically for all other
+ * leaf entries, or for the top root, or middle one, for which there is a void
+ * entry, we assume it is "missing". So (for example)
+ * pfn_to_mfn(0x90909090)=INVALID_P2M_ENTRY.
+ *
+ * We also have the possibility of setting 1-1 mappings on certain regions, so
+ * that:
+ * pfn_to_mfn(0xc0000)=0xc0000
+ *
+ * The benefit of this is, that we can assume for non-RAM regions (think
+ * PCI BARs, or ACPI spaces), we can create mappings easily b/c we
+ * get the PFN value to match the MFN.
+ *
+ * For this to work efficiently we have one new page p2m_identity and
+ * allocate (via reserved_brk) any other pages we need to cover the sides
+ * (1GB or 4MB boundary violations). All entries in p2m_identity are set to
+ * INVALID_P2M_ENTRY type (Xen toolstack only recognizes that and MFNs,
+ * no other fancy value).
+ *
+ * On lookup we spot that the entry points to p2m_identity and return the
+ * identity value instead of dereferencing and returning INVALID_P2M_ENTRY.
+ * If the entry points to an allocated page, we just proceed as before and
+ * return the PFN. If the PFN has IDENTITY_FRAME_BIT set we unmask that in
+ * appropriate functions (pfn_to_mfn).
+ *
+ * The reason for having the IDENTITY_FRAME_BIT instead of just returning the
+ * PFN is that we could find ourselves where pfn_to_mfn(pfn)==pfn for a
+ * non-identity pfn. To protect ourselves against we elect to set (and get) the
+ * IDENTITY_FRAME_BIT on all identity mapped PFNs.
+ *
+ * This simplistic diagram is used to explain the more subtle piece of code.
+ * There is also a digram of the P2M at the end that can help.
+ * Imagine your E820 looking as so:
+ *
+ * 1GB 2GB
+ * /-------------------+---------\/----\ /----------\ /---+-----\
+ * | System RAM | Sys RAM ||ACPI| | reserved | | Sys RAM |
+ * \-------------------+---------/\----/ \----------/ \---+-----/
+ * ^- 1029MB ^- 2001MB
+ *
+ * [1029MB = 263424 (0x40500), 2001MB = 512256 (0x7D100),
+ * 2048MB = 524288 (0x80000)]
+ *
+ * And dom0_mem=max:3GB,1GB is passed in to the guest, meaning memory past 1GB
+ * is actually not present (would have to kick the balloon driver to put it in).
+ *
+ * When we are told to set the PFNs for identity mapping (see patch: "xen/setup:
+ * Set identity mapping for non-RAM E820 and E820 gaps.") we pass in the start
+ * of the PFN and the end PFN (263424 and 512256 respectively). The first step
+ * is to reserve_brk a top leaf page if the p2m[1] is missing. The top leaf page
+ * covers 512^2 of page estate (1GB) and in case the start or end PFN is not
+ * aligned on 512^2*PAGE_SIZE (1GB) we loop on aligned 1GB PFNs from start pfn
+ * to end pfn. We reserve_brk top leaf pages if they are missing (means they
+ * point to p2m_mid_missing).
+ *
+ * With the E820 example above, 263424 is not 1GB aligned so we allocate a
+ * reserve_brk page which will cover the PFNs estate from 0x40000 to 0x80000.
+ * Each entry in the allocate page is "missing" (points to p2m_missing).
+ *
+ * Next stage is to determine if we need to do a more granular boundary check
+ * on the 4MB (or 2MB depending on architecture) off the start and end pfn's.
+ * We check if the start pfn and end pfn violate that boundary check, and if
+ * so reserve_brk a middle (p2m[x][y]) leaf page. This way we have a much finer
+ * granularity of setting which PFNs are missing and which ones are identity.
+ * In our example 263424 and 512256 both fail the check so we reserve_brk two
+ * pages. Populate them with INVALID_P2M_ENTRY (so they both have "missing"
+ * values) and assign them to p2m[1][2] and p2m[1][488] respectively.
+ *
+ * At this point we would at minimum reserve_brk one page, but could be up to
+ * three. Each call to set_phys_range_identity has at maximum a three page
+ * cost. If we were to query the P2M at this stage, all those entries from
+ * start PFN through end PFN (so 1029MB -> 2001MB) would return
+ * INVALID_P2M_ENTRY ("missing").
+ *
+ * The next step is to walk from the start pfn to the end pfn setting
+ * the IDENTITY_FRAME_BIT on each PFN. This is done in set_phys_range_identity.
+ * If we find that the middle leaf is pointing to p2m_missing we can swap it
+ * over to p2m_identity - this way covering 4MB (or 2MB) PFN space. At this
+ * point we do not need to worry about boundary aligment (so no need to
+ * reserve_brk a middle page, figure out which PFNs are "missing" and which
+ * ones are identity), as that has been done earlier. If we find that the
+ * middle leaf is not occupied by p2m_identity or p2m_missing, we dereference
+ * that page (which covers 512 PFNs) and set the appropriate PFN with
+ * IDENTITY_FRAME_BIT. In our example 263424 and 512256 end up there, and we
+ * set from p2m[1][2][256->511] and p2m[1][488][0->256] with
+ * IDENTITY_FRAME_BIT set.
+ *
+ * All other regions that are void (or not filled) either point to p2m_missing
+ * (considered missing) or have the default value of INVALID_P2M_ENTRY (also
+ * considered missing). In our case, p2m[1][2][0->255] and p2m[1][488][257->511]
+ * contain the INVALID_P2M_ENTRY value and are considered "missing."
+ *
+ * This is what the p2m ends up looking (for the E820 above) with this
+ * fabulous drawing:
+ *
+ * p2m /--------------\
+ * /-----\ | &mfn_list[0],| /-----------------\
+ * | 0 |------>| &mfn_list[1],| /---------------\ | ~0, ~0, .. |

- * "Never use this function, bad things will happen" - gregkh
+ * Note: Don't call this function. Currently, the networking layer calls this
+ * function, but that will change. The following text from Kay Sievers offers
+ * some insight:
+ *
+ * Renaming devices is racy at many levels, symlinks and other stuff are not
+ * replaced atomically, and you get a "move" uevent, but it's not easy to
+ * connect the event to the old and new device. Device nodes are not renamed at
+ * all, there isn't even support for that in the kernel now.
+ *
+ * In the meantime, during renaming, your target name might be taken by another
+ * driver, creating conflicts. Or the old name is taken directly after you
+ * renamed it -- then you get events for the same DEVPATH, before you even see
+ * the "move" event. It's just a mess, and nothing new should ever rely on
+ * kernel device renaming. Besides that, it's not even implemented now for
+ * other things than (driver-core wise very simple) network devices.
+ *
+ * We are currently about to change network renaming in udev to completely
+ * disallow renaming of devices in the same namespace as the kernel uses,
+ * because we can't solve the problems properly, that arise with swapping names
+ * of multiple interfaces without races. Means, renaming of eth[0-9]* will only
+ * be allowed to some other name than eth[0-9]*, for the aforementioned
+ * reasons.
+ *
+ * Make up a "real" name in the driver before you register anything, or add
+ * some other attributes for userspace to find the device, or use udev to add
+ * symlinks -- but never rename kernel devices later, it's a complete mess. We
+ * don't even want to get into that and try to implement the missing pieces in
+ * the core. We really have other pieces to fix in the driver core mess. :)

- ---help---
- If you say Y here, you will get support for terminal devices with
- display and keyboard devices. These are called "virtual" because you
- can run several virtual terminals (also called virtual consoles) on
- one physical terminal. This is rather useful, for example one
- virtual terminal can collect system messages and warnings, another
- one can be used for a text-mode user session, and a third could run
- an X session, all in parallel. Switching between virtual terminals
- is done with certain key combinations, usually Alt-<function key>.
-
- The setterm command ("man setterm") can be used to change the
- properties (such as colors or beeping) of a virtual terminal. The
- man page console_codes(4) ("man console_codes") contains the special
- character sequences that can be used to change those properties
- directly. The fonts used on virtual terminals can be changed with
- the setfont ("man setfont") command and the key bindings are defined
- with the loadkeys ("man loadkeys") command.
-
- You need at least one virtual terminal device in order to make use
- of your keyboard and monitor. Therefore, only people configuring an
- embedded system would want to say N here in order to save some

- common mode of operations, so you should say Y here unless you want
- the kernel messages be output only to a serial port (in which case
- you should say Y to "Console on serial port", below).
-
- If you do say Y here, by default the currently visible virtual
- terminal (/dev/tty0) will be used as system console. You can change
- that with a kernel command line option such as "console=tty3" which
- would use the third virtual terminal as system console. (Try "man

+ *
+ * - The hardware may not be capable of filling them in;
+ * many alarms match only on time-of-day fields, not
+ * day/month/year calendar data.
+ *
+ * - Some hardware uses illegal values as "wildcard" match
+ * values, which non-Linux firmware (like a BIOS) may try
+ * to set up as e.g. "alarm 15 minutes after each hour".
+ * Linux uses only oneshot alarms.
+ *
+ * When we see that here, we deal with it by using values from
+ * a current RTC timestamp for any missing (-1) values. The
+ * RTC driver prevents "periodic alarm" modes.
+ *
+ * But this can be racey, because some fields of the RTC timestamp
+ * may have wrapped in the interval since we read the RTC alarm,
+ * which would lead to us inserting inconsistent values in place
+ * of the -1 fields.
+ *
+ * Reading the alarm and timestamp in the reverse sequence
+ * would have the same race condition, and not solve the issue.
+ *
+ * So, we must first read the RTC timestamp,
+ * then read the RTC alarm value,
+ * and then read a second RTC timestamp.
+ *
+ * If any fields of the second timestamp have changed
+ * when compared with the first timestamp, then we know
+ * our timestamp may be inconsistent with that used by
+ * the low-level rtc_read_alarm_internal() function.
+ *
+ * So, when the two timestamps disagree, we just loop and do
+ * the process again to get a fully consistent set of values.
+ *
+ * This could all instead be done in the lower level driver,
+ * but since more than one lower level RTC implementation needs it,
+ * then it's probably best best to do it here instead of there..

- tristate "Kernel automounter support"
- depends on BKL # unfixable, just use autofs4
- help
- The automounter is a tool to automatically mount remote file systems
- on demand. This implementation is partially kernel-based to reduce
- overhead in the already-mounted case; this is unlike the BSD
- automounter (amd), which is a pure user space daemon.
-
- To use the automounter you need the user-space tools from the autofs
- package; you can find the location in <file:Documentation/Changes>.
- You also want to answer Y to "NFS file system support", below.
-
- If you want to use the newer version of the automounter with more
- features, say N here and say Y to "Kernel automounter v4 support",
- below.
-
- To compile this support as a module, choose M here: the module will be
- called autofs.
-
- If you are not a part of a fairly large, distributed network, you
- probably do not need an automounter, and can say N here.

+ depends on EXPERIMENTAL && ZORRO && BROKEN
+ ---help---
+ This option supports the 2232 7-port serial card shipped with the
+ Amiga 2000 and other Zorro-bus machines, dating from 1989. At
+ a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
+ each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
+ ports were connected with 8 pin DIN connectors on the card bracket,
+ for which 8 pin to DB25 adapters were supplied. The card also had
+ jumpers internally to toggle various pinning configurations.
+
+ This driver can be built as a module; but then "generic_serial"
+ will also be built as a module. This has to be loaded before
+ "ser_a2232". If you want to do this, answer M here.
+
+config SX
+ tristate "Specialix SX (and SI) card support"
+ depends on SERIAL_NONSTANDARD && (PCI || EISA || ISA) && BROKEN
+ help
+ This is a driver for the SX and SI multiport serial cards.
+ Please read the file <file:Documentation/serial/sx.txt> for details.
+
+ This driver can only be built as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want).
+ The module will be called sx. If you want to do that, say M here.
+
+config RIO
+ tristate "Specialix RIO system support"
+ depends on SERIAL_NONSTANDARD && BROKEN
+ help
+ This is a driver for the Specialix RIO, a smart serial card which
+ drives an outboard box that can support up to 128 ports. Product
+ information is at <http://www.perle.com/support/documentation.html#multiport>.
+ There are both ISA and PCI versions.
+
+config RIO_OLDPCI
+ bool "Support really old RIO/PCI cards"
+ depends on RIO
+ help
+ Older RIO PCI cards need some initialization-time configuration to
+ determine the IRQ and some control addresses. If you have a RIO and
+ this doesn't seem to work, try setting this to Y.

+- Test on more platforms
+- Clean up the various chunks of unused code
+- Sort out the power management side. Not important for Poulsbo but
+ matters for Moorestown
+- Add Moorestown support (single pipe, no BIOS, no stolen memory,
+ some other differences)
+- Sort out the bo and ttm code to support userframe buffers and DRM
+ interfaces rather than just faking it enough for a framebuffer
+- Add 2D acceleration via console and DRM
+
+As per kernel policy and the in the interest of the safety of various
+kittens there is no support or plans to add hooks for the closed user space
+stuff.
+
+
+Why bother ?
+- Proper display configuration
+- Can be made to work on Moorestown where VESA won't
+- Works on systems where the VESA BIOS is bust or the tables are broken
+ without hacks
+- 2D acceleration
+
+Currently tested on
++ Dell Mini 10 100x600

+ * 1) The kernel component which is packaged as part of the hv_utils driver
+ * is responsible for communicating with the host and responsible for
+ * implementing the host/guest protocol. 2) A user level daemon that is
+ * responsible for data gathering.
+ *
+ * Host/Guest Protocol: The host iterates over an index and expects the guest
+ * to assign a key name to the index and also return the value corresponding to
+ * the key. The host will have atmost one KVP transaction outstanding at any
+ * given point in time. The host side iteration stops when the guest returns
+ * an error. Microsoft has specified the following mapping of key names to
+ * host specified index:
+ *
+ * Index Key Name
+ * 0 FullyQualifiedDomainName
+ * 1 IntegrationServicesVersion
+ * 2 NetworkAddressIPv4
+ * 3 NetworkAddressIPv6
+ * 4 OSBuildNumber
+ * 5 OSName
+ * 6 OSMajorVersion
+ * 7 OSMinorVersion
+ * 8 OSVersion
+ * 9 ProcessorArchitecture
+ *
+ * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ *
+ * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
+ * data gathering functionality in a user mode daemon. The user level daemon
+ * is also responsible for binding the key name to the index as well. The
+ * kernel and user-level daemon communicate using a connector channel.
+ *
+ * The user mode component first registers with the
+ * the kernel component. Subsequently, the kernel component requests, data
+ * for the specified keys. In response to this message the user mode component
+ * fills in the value corresponding to the specified key. We overload the
+ * sequence field in the cn_msg header to define our KVP message types.
+ *
+ *
+ * The kernel component simply acts as a conduit for communication between the
+ * Windows host and the user-level daemon. The kernel component passes up the
+ * index received from the Host to the user-level daemon. If the index is
+ * valid (supported), the corresponding key as well as its
+ * value (both are strings) is returned. If the index is invalid
+ * (not supported), a NULL key string is returned.
+ */

+Kernel driver max517
+====================
+
+Supported chips:
+ * Maxim MAX517, MAX518, MAX519
+ Prefix: 'max517'
+ Datasheet: Publicly available at the Maxim website
+ http://www.maxim-ic.com/
+
+Author:
+ Roland Stigge <stigge@antcom.de>
+
+Description
+-----------
+
+The Maxim MAX517/518/519 is an 8-bit DAC on the I2C bus. The following table
+shows the different feature sets of the variants MAX517, MAX518 and MAX519:
+
+Feature MAX517 MAX518 MAX519
+--------------------------------------------------------------------------
+One output channel X
+Two output channels X X
+Simultaneous output updates X X
+Supply voltage as reference X
+Separate reference input X
+Reference input for each DAC X
+
+Via the iio sysfs interface, there are three attributes available: out1_raw,
+out2_raw and out12_raw. With out1_raw and out2_raw, the current output values
+(0..255) of the DACs can be written to the device. out12_raw can be used to set
+both output channel values simultaneously.
+
+With MAX517, only out1_raw is available.
+
+Via out1_scale (and where appropriate, out2_scale), the current scaling factor
+in mV can be read.
+
+When the operating system goes to a power down state, the Power Down function
+of the chip is activated, reducing the supply current to 4uA.
+
+On power-up, the device is in 0V-output state.

- SMB (Server Message Block) is the protocol Windows for Workgroups
- (WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
- files and printers over local networks. Saying Y here allows you to
- mount their file systems (often called "shares" in this context) and
- access them just like any other Unix directory. Currently, this
- works only if the Windows machines use TCP/IP as the underlying
- transport protocol, and not NetBEUI. For details, read
- <file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
- available from <http://www.tldp.org/docs.html#howto>.
-
- Note: if you just want your box to act as an SMB *server* and make
- files and printing services available to Windows clients (which need
- to have a TCP/IP stack), you don't need to say Y here; you can use
- the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
- for that.
-
- General information about how to connect Linux, Windows machines and
- Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.

-Smbfs is a filesystem that implements the SMB protocol, which is the
-protocol used by Windows for Workgroups, Windows 95 and Windows NT.
-Smbfs was inspired by Samba, the program written by Andrew Tridgell
-that turns any Unix host into a file server for DOS or Windows clients.
-
-Smbfs is a SMB client, but uses parts of samba for its operation. For
-more info on samba, including documentation, please go to
-http://www.samba.org/ and then on to your nearest mirror.

- * element. So the next element after the head becomes the new head of

- * NULL No elements in list
- * Requires:

+ * Copyright (c) 2009-2011, Dan Magenheimer, Oracle Corp.
+ *
+ * The primary purpose of Transcedent Memory ("tmem") is to map object-oriented
+ * "handles" (triples containing a pool id, and object id, and an index), to
+ * pages in a page-accessible memory (PAM). Tmem references the PAM pages via
+ * an abstract "pampd" (PAM page-descriptor), which can be operated on by a
+ * set of functions (pamops). Each pampd contains some representation of
+ * PAGE_SIZE bytes worth of data. Tmem must support potentially millions of
+ * pages and must be able to insert, find, and delete these pages at a
+ * potential frequency of thousands per second concurrently across many CPUs,
+ * (and, if used with KVM, across many vcpus across many guests).
+ * Tmem is tracked with a hierarchy of data structures, organized by
+ * the elements in a handle-tuple: pool_id, object_id, and page index.
+ * One or more "clients" (e.g. guests) each provide one or more tmem_pools.
+ * Each pool, contains a hash table of rb_trees of tmem_objs. Each
+ * tmem_obj contains a radix-tree-like tree of pointers, with intermediate
+ * nodes called tmem_objnodes. Each leaf pointer in this tree points to
+ * a pampd, which is accessible only through a small set of callbacks
+ * registered by the PAM implementation (see tmem_register_pamops). Tmem
+ * does all memory allocation via a set of callbacks registered by the tmem
+ * host implementation (e.g. see tmem_register_hostops).

+ default y
+ ---help---
+ If you say Y here, you will get support for terminal devices with
+ display and keyboard devices. These are called "virtual" because you
+ can run several virtual terminals (also called virtual consoles) on
+ one physical terminal. This is rather useful, for example one
+ virtual terminal can collect system messages and warnings, another
+ one can be used for a text-mode user session, and a third could run
+ an X session, all in parallel. Switching between virtual terminals
+ is done with certain key combinations, usually Alt-<function key>.
+
+ The setterm command ("man setterm") can be used to change the
+ properties (such as colors or beeping) of a virtual terminal. The
+ man page console_codes(4) ("man console_codes") contains the special
+ character sequences that can be used to change those properties
+ directly. The fonts used on virtual terminals can be changed with
+ the setfont ("man setfont") command and the key bindings are defined
+ with the loadkeys ("man loadkeys") command.
+
+ You need at least one virtual terminal device in order to make use
+ of your keyboard and monitor. Therefore, only people configuring an
+ embedded system would want to say N here in order to save some
+ memory; the only way to log into such a system is then via a serial
+ or network connection.

+ ---help---
+ The system console is the device which receives all kernel messages
+ and warnings and which allows logins in single user mode. If you
+ answer Y here, a virtual terminal (the device used to interact with
+ a physical terminal) can be used as system console. This is the most
+ common mode of operations, so you should say Y here unless you want
+ the kernel messages be output only to a serial port (in which case
+ you should say Y to "Console on serial port", below).
+
+ If you do say Y here, by default the currently visible virtual
+ terminal (/dev/tty0) will be used as system console. You can change
+ that with a kernel command line option such as "console=tty3" which
+ would use the third virtual terminal as system console. (Try "man
+ bootparam" or see the documentation of your boot loader (lilo or

+ 1 console driver is enabled, setting this to 'y' will allow you to
+ select the console driver that will serve as the backend for the

+ A pseudo terminal (PTY) is a software device consisting of two

+ read data from and write data to the slave, thereby emulating a
+ terminal. Typical programs for the master side are telnet servers
+ and xterms.
+
+ Linux has traditionally used the BSD-like names /dev/ptyxx for
+ masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
+ has a number of problems. The GNU C library glibc 2.1 and later,
+ however, supports the Unix98 naming standard: in order to acquire a
+ pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
+ terminal is then made available to the process and the pseudo
+ terminal slave can be accessed as /dev/pts/<number>. What was
+ traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
+

+ * TODO (last updated Feb 27, 2011):
* - add kernel-doc
- * - Factor out code common to EHCI to a separate file
- * - Make EHCI and OHCI coexist together
- * - needs newer silicon versions to actually work
- * - the last one to be loaded currently steps on the other's toes
- * - Add hooks for configuring transceivers, etc. at init/exit

+ Say Y here if you wish to control a ENE SD Card reader.
+ To use SM/MS card, please build driver/staging/keucr/keucr.ko
+
+ This option depends on 'SCSI' support being enabled, but you
+ probably also need 'SCSI device support: SCSI disk support'
+ (BLK_DEV_SD) for most USB storage devices.
+
+ To compile this driver as a module, choose M here: the
+ module will be called ums-eneub6250.

- "Power Management" means that parts of your computer are shut

- being used. There are two competing standards for doing this: APM
- and ACPI. If you want to use either one, say Y here and then also
- to the requisite support below.
-
- Power Management is most important for battery powered laptop
- computers; if you have a laptop, check out the Linux Laptop home
- page on the WWW at <http://www.linux-on-laptops.com/> or
- Tuxmobil - Linux on Mobile Computers at <http://www.tuxmobil.org/>
- and the Battery Powered Linux mini-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- Note that, even if you say N here, Linux on the x86 architecture
- will issue the hlt instruction if nothing is to be done, thereby
- sending the processor to sleep and saving power.

+ during suspend (or more commonly, during resume).
+
+ To use this debugging feature you should attempt to suspend the
+ machine, reboot it and then run
+
+ dmesg -s 1000000 | grep 'hash matches'

+ CAUTION: this option will cause your machine's real-time clock to be

+Without options all known events will be listed.
+
+To limit the list use:
+
+. 'hw' or 'hardware' to list hardware events such as cache-misses, etc.
+
+. 'sw' or 'software' to list software events such as context switches, etc.
+
+. 'cache' or 'hwcache' to list hardware cache events such as L1-dcache-loads, etc.
+
+. 'tracepoint' to list all tracepoint events, alternatively use
+ 'subsys_glob:event_glob' to filter by tracepoint subsystems such as sched,
+ block, etc.
+
+. If none of the above is matched, it will apply the supplied glob to all
+ events, printing the ones that match.
+
+One or more types can be used at the same time, listing the events for the
+types specified.

-----------
Line range is described by following syntax.
- "FUNC[:RLN[+NUM|-RLN2]]|SRC[:ALN[+NUM|-ALN2]]"
+ "FUNC[@SRC][:RLN[+NUM|-RLN2]]|SRC[:ALN[+NUM|-ALN2]]"
FUNC specifies the function name of showing lines. 'RLN' is the start line
number from function entry line, and 'RLN2' is the end line number. As same as
probe syntax, 'SRC' means the source file path, 'ALN' is start line number,
and 'ALN2' is end line number in the file. It is also possible to specify how
-many lines to show by using 'NUM'.
+many lines to show by using 'NUM'. Moreover, 'FUNC@SRC' combination is good
+for searching a specific function when several functions share same name.
So, "source.c:100-120" shows lines between 100th to l20th in source.c file. And "func:10+20" shows 20 lines from 10th line of func function.
LAZY MATCHING
@@ -135,6 +147,14 @@
This provides some sort of flexibility and robustness to probe point definitions against minor code changes. For example, actual 10th line of schedule() can be moved easily by modifying schedule(), but the same line matching 'rq=cpu_rq*' may still exist in the function.)
+FILTER PATTERN
+--------------
+ The filter pattern is a glob matching pattern(s) to filter variables.
+ In addition, you can use "!" for specifying filter-out rule. You also can give several rules combined with "&" or "|", and fold those rules as one rule by using "(" ")".
+
+e.g.
+ With --filter "foo* | bar*", perf probe -V shows variables which start with "foo" or "bar".
+ With --filter "!foo* & *bar", perf probe -V shows variables which don't start with "foo" and end with "bar", like "fizzbar". But "foobar" is filtered out.
