+ACPI based device enumeration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ACPI 5 introduced a set of new resources (UartTSerialBus, I2cSerialBus,
+SpiSerialBus, GpioIo and GpioInt) which can be used in enumerating slave
+devices behind serial bus controllers.
+
+In addition we are starting to see peripherals integrated in the
+SoC/Chipset to appear only in ACPI namespace. These are typically devices
+that are accessed through memory-mapped registers.
+
+In order to support this and re-use the existing drivers as much as
+possible we decided to do following:
+
+	o Devices that have no bus connector resource are represented as
+	  platform devices.
+
+	o Devices behind real busses where there is a connector resource
+	  are represented as struct spi_device or struct i2c_device
+	  (standard UARTs are not busses so there is no struct uart_device).
+
+As both ACPI and Device Tree represent a tree of devices (and their
+resources) this implementation follows the Device Tree way as much as
+possible.
+
+The ACPI implementation enumerates devices behind busses (platform, SPI and
+I2C), creates the physical devices and binds them to their ACPI handle in
+the ACPI namespace.
+
+This means that when ACPI_HANDLE(dev) returns non-NULL the device was
+enumerated from ACPI namespace. This handle can be used to extract other
+device-specific configuration. There is an example of this below.
+
+Platform bus support
+~~~~~~~~~~~~~~~~~~~~
+Since we are using platform devices to represent devices that are not
+connected to any physical bus we only need to implement a platform driver
+for the device and add supported ACPI IDs. If this same IP-block is used on
+some other non-ACPI platform, the driver might work out of the box or needs
+some minor changes.
+
+Adding ACPI support for an existing driver should be pretty
+straightforward. Here is the simplest example:
+
+	#ifdef CONFIG_ACPI
+	static struct acpi_device_id mydrv_acpi_match[] = {
+		/* ACPI IDs here */
+		{ }
+	};
+	MODULE_DEVICE_TABLE(acpi, mydrv_acpi_match);
+	#endif
+
+	static struct platform_driver my_driver = {
+		...
+		.driver = {
+			.acpi_match_table = ACPI_PTR(mydrv_acpi_match),
+		},
+	};
+
+If the driver needs to perform more complex initialization like getting and
+configuring GPIOs it can get its ACPI handle and extract this information
+from ACPI tables.
+
+Currently the kernel is not able to automatically determine from which ACPI
+device it should make the corresponding platform device so we need to add
+the ACPI device explicitly to acpi_platform_device_ids list defined in
+drivers/acpi/scan.c. This limitation is only for the platform devices, SPI
+and I2C devices are created automatically as described below.
+
+SPI serial bus support
+~~~~~~~~~~~~~~~~~~~~~~
+Slave devices behind SPI bus have SpiSerialBus resource attached to them.
+This is extracted automatically by the SPI core and the slave devices are
+enumerated once spi_register_master() is called by the bus driver.
+
+Here is what the ACPI namespace for a SPI slave might look like:
+
+	Device (EEP0)
+	{
+		Name (_ADR, 1)
+		Name (_CID, Package() {
+			"ATML0025",
+			"AT25",
+		})
+		...
+		Method (_CRS, 0, NotSerialized)
+		{
+			SPISerialBus(1, PolarityLow, FourWireMode, 8,
+				ControllerInitiated, 1000000, ClockPolarityLow,
+				ClockPhaseFirst, "\\_SB.PCI0.SPI1",)
+		}
+		...
+
+The SPI device drivers only need to add ACPI IDs in a similar way than with
+the platform device drivers. Below is an example where we add ACPI support
+to at25 SPI eeprom driver (this is meant for the above ACPI snippet):
+
+	#ifdef CONFIG_ACPI
+	static struct acpi_device_id at25_acpi_match[] = {
+		{ "AT25", 0 },
+		{ },
+	};
+	MODULE_DEVICE_TABLE(acpi, at25_acpi_match);
+	#endif
+
+	static struct spi_driver at25_driver = {
+		.driver = {
+			...
+			.acpi_match_table = ACPI_PTR(at25_acpi_match),
+		},
+	};
+
+Note that this driver actually needs more information like page size of the
+eeprom etc. but at the time writing this there is no standard way of
+passing those. One idea is to return this in _DSM method like:
+
+	Device (EEP0)
+	{
+		...
+		Method (_DSM, 4, NotSerialized)
+		{
+			Store (Package (6)
+			{
+				"byte-len", 1024,
+				"addr-mode", 2,
+				"page-size, 32
+			}, Local0)
+
+			// Check UUIDs etc.
+
+			Return (Local0)
+		}
+
+Then the at25 SPI driver can get this configation by calling _DSM on its
+ACPI handle like:
+
+	struct acpi_buffer output = { ACPI_ALLOCATE_BUFFER, NULL };
+	struct acpi_object_list input;
+	acpi_status status;
+
+	/* Fill in the input buffer */
+
+	status = acpi_evaluate_object(ACPI_HANDLE(&spi->dev), "_DSM",
+				      &input, &output);
+	if (ACPI_FAILURE(status))
+		/* Handle the error */
+
+	/* Extract the data here */
+
+	kfree(output.pointer);
+
+I2C serial bus support
+~~~~~~~~~~~~~~~~~~~~~~
+The slaves behind I2C bus controller only need to add the ACPI IDs like
+with the platform and SPI drivers. However the I2C bus controller driver
+needs to call acpi_i2c_register_devices() after it has added the adapter.
+
+An I2C bus (controller) driver does:
+
+	...
+	ret = i2c_add_numbered_adapter(adapter);
+	if (ret)
+		/* handle error */
+
+	of_i2c_register_devices(adapter);
+	/* Enumerate the slave devices behind this bus via ACPI */
+	acpi_i2c_register_devices(adapter);
+
+Below is an example of how to add ACPI support to the existing mpu3050
+input driver:
+
+	#ifdef CONFIG_ACPI
+	static struct acpi_device_id mpu3050_acpi_match[] = {
+		{ "MPU3050", 0 },

+
+GPIO support
+~~~~~~~~~~~~
+ACPI 5 introduced two new resources to describe GPIO connections: GpioIo
+and GpioInt. These resources are used be used to pass GPIO numbers used by
+the device to the driver. For example:
+
+	Method (_CRS, 0, NotSerialized)
+	{
+		Name (SBUF, ResourceTemplate()
+		{
+			GpioIo (Exclusive, PullDefault, 0x0000, 0x0000,
+				IoRestrictionOutputOnly, "\\_SB.PCI0.GPI0",
+				0x00, ResourceConsumer,,)
+			{
+				// Pin List
+				0x0055
+			}
+			...
+
+			Return (SBUF)
+		}
+	}
+
+These GPIO numbers are controller relative and path "\\_SB.PCI0.GPI0"
+specifies the path to the controller. In order to use these GPIOs in Linux
+we need to translate them to the Linux GPIO numbers.
+
+The driver can do this by including <linux/acpi_gpio.h> and then calling
+acpi_get_gpio(path, gpio). This will return the Linux GPIO number or
+negative errno if there was no translation found.
+
+Other GpioIo parameters must be converted first by the driver to be
+suitable to the gpiolib before passing them.
+
+In case of GpioInt resource an additional call to gpio_to_irq() must be
+done before calling request_irq().

+=== ST Microelectronics SPEAr SPI CS Driver ===
+
+SPEAr platform provides a provision to control chipselects of ARM PL022 Prime
+Cell spi controller through its system registers, which otherwise remains under
+PL022 control. If chipselect remain under PL022 control then they would be
+released as soon as transfer is over and TxFIFO becomes empty. This is not
+desired by some of the device protocols above spi which expect (multiple)
+transfers without releasing their chipselects.
+
+Chipselects can be controlled by software by turning them as GPIOs. SPEAr
+provides another interface through system registers through which software can
+directly control each PL022 chipselect. Hence, it is natural for SPEAr to export
+the control of this interface as gpio.
+
+Required properties:
+
+  * compatible: should be defined as "st,spear-spics-gpio"
+  * reg: mentioning address range of spics controller
+  * st-spics,peripcfg-reg: peripheral configuration register offset
+  * st-spics,sw-enable-bit: bit offset to enable sw control
+  * st-spics,cs-value-bit: bit offset to drive chipselect low or high
+  * st-spics,cs-enable-mask: chip select number bit mask
+  * st-spics,cs-enable-shift: chip select number program offset
+  * gpio-controller: Marks the device node as gpio controller
+  * #gpio-cells: should be 1 and will mention chip select number
+
+All the above bit offsets are within peripcfg register.
+
+Example:
+-------
+spics: spics@e0700000{
+        compatible = "st,spear-spics-gpio";
+        reg = <0xe0700000 0x1000>;

+        st-spics,cs-enable-mask = <3>;
+        st-spics,cs-enable-shift = <8>;

-Linux Quicknet-Drivers-Howto
-Quicknet Technologies, Inc. (www.quicknet.net)
-Version 0.3.4  December 18, 1999
-
-1.0  Introduction
-
-This document describes the first GPL release version of the Linux
-driver for the Quicknet Internet PhoneJACK and Internet LineJACK
-cards.  More information about these cards is available at
-www.quicknet.net.  The driver version discussed in this document is
-0.3.4.
-
-These cards offer nice telco style interfaces to use your standard
-telephone/key system/PBX as the user interface for VoIP applications.
-The Internet LineJACK also offers PSTN connectivity for a single line
-Internet to PSTN gateway.  Of course, you can add more than one card
-to a system to obtain multi-line functionality.  At this time, the
-driver supports the POTS port on both the Internet PhoneJACK and the
-Internet LineJACK, but the PSTN port on the latter card is not yet
-supported.
-
-This document, and the drivers for the cards, are intended for a
-limited audience that includes technically capable programmers who
-would like to experiment with Quicknet cards.  The drivers are
-considered in ALPHA status and are not yet considered stable enough
-for general, widespread use in an unlimited audience.
-
-That's worth saying again:
-
-THE LINUX DRIVERS FOR QUICKNET CARDS ARE PRESENTLY IN A ALPHA STATE
-AND SHOULD NOT BE CONSIDERED AS READY FOR NORMAL WIDESPREAD USE.
-
-They are released early in the spirit of Internet development and to
-make this technology available to innovators who would benefit from
-early exposure.
-
-When we promote the device driver to "beta" level it will be
-considered ready for non-programmer, non-technical users.  Until then,
-please be aware that these drivers may not be stable and may affect
-the performance of your system.
-
-
-1.1 Latest Additions/Improvements
-
-The 0.3.4 version of the driver is the first GPL release.  Several
-features had to be removed from the prior binary only module, mostly
-for reasons of Intellectual Property rights.  We can't release
-information that is not ours - so certain aspects of the driver had to
-be removed to protect the rights of others.  
-
-Specifically, very old Internet PhoneJACK cards have non-standard
-G.723.1 codecs (due to the early nature of the DSPs in those days).
-The auto-conversion code to bring those cards into compliance with
-today's standards is available as a binary only module to those people
-needing it.  If you bought your card after 1997 or so, you are OK -
-it's only the very old cards that are affected.
-
-Also, the code to download G.728/G.729/G.729a codecs to the DSP is
-available as a binary only module as well.  This IP is not ours to
-release.  
-
-Hooks are built into the GPL driver to allow it to work with other
-companion modules that are completely separate from this module.

-
-2.0  Requirements
-
-2.1  Quicknet Card(s)
-
-You will need at least one Internet PhoneJACK or Internet LineJACK
-cards.  These are ISA or PCI bus devices that use Plug-n-Play for
-configuration, and use no IRQs.  The driver will support up to 16
-cards in any one system, of any mix between the two types.
-
-Note that you will need two cards to do any useful testing alone, since
-you will need a card on both ends of the connection.  Of course, if
-you are doing collaborative work, perhaps your friends or coworkers
-have cards too.  If not, we'll gladly sell them some!
-
-
-2.2  ISAPNP
-
-Since the Quicknet cards are Plug-n-Play devices, you will need the
-isapnp tools package to configure the cards, or you can use the isapnp
-module to autoconfigure them.  The former package probably came with
-your Linux distribution.  Documentation on this package is available
-online at:
-
-http://mailer.wiwi.uni-marburg.de/linux/LDP/HOWTO/Plug-and-Play-HOWTO.html
-
-The isapnp autoconfiguration is available on the Quicknet website at:
-
-    http://www.quicknet.net/develop.htm
-
-though it may be in the kernel by the time you read this.
-
-
-3.0  Card Configuration 
-
-If you did not get your drivers as part of the linux kernel, do the
-following to install them:
-
-   a.  untar the distribution file.  We use the following command:
-        tar -xvzf ixj-0.x.x.tgz
-
-This creates a subdirectory holding all the necessary files.  Go to that
-subdirectory.
-
-   b.  run the "ixj_dev_create" script to remove any stray device
-files left in the /dev directory, and to create the new officially
-designated device files.  Note that the old devices were called 
-/dev/ixj, and the new method uses /dev/phone.  
-
-   c.  type "make;make install" - this will compile and install the
-module.
-
-   d.  type "depmod -av" to rebuild all your kernel version dependencies.
-
-   e.  if you are using the isapnp module to configure the cards
-       automatically, then skip to step f.  Otherwise, ensure that you
-       have run the isapnp configuration utility to properly configure
-       the cards.
-
-       e1. The Internet PhoneJACK has one configuration register that
-           requires 16 IO ports.  The Internet LineJACK card has two
-           configuration registers and isapnp reports that IO 0
-           requires 16 IO ports and IO 1 requires 8.  The Quicknet
-           driver assumes that these registers are configured to be
-           contiguous, i.e. if IO 0 is set to 0x340 then IO 1 should
-           be set to 0x350.
-
-           Make sure that none of the cards overlap if you have
-           multiple cards in the system.
-
-           If you are new to the isapnp tools, you can jumpstart
-           yourself by doing the following:
-
-      e2.  go to the /etc directory and run pnpdump to get a blank
-           isapnp.conf file.
-
-	   	pnpdump > /etc/isapnp.conf
-
-      e3.  edit the /etc/isapnp.conf file to set the IO warnings and
-           the register IO addresses. The IO warnings means that you
-           should find the line in the file that looks like this:
-
-	   (CONFLICT (IO FATAL)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # or WARNING
-
-	   and you should edit the line to look like this:
-
-	   (CONFLICT (IO WARNING)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) #
-	   or WARNING
-
-           The next step is to set the IO port addresses.  The issue
-           here is that isapnp does not identify all of the ports out
-           there.  Specifically any device that does not have a driver
-           or module loaded by Linux will not be registered.  This
-           includes older sound cards and network cards.  We have
-           found that the IO port 0x300 is often used even though
-           isapnp claims that no-one is using those ports.  We
-           recommend that for a single card installation that port
-           0x340 (and 0x350) be used.  The IO port line should change
-           from this:
-
-	   (IO 0 (SIZE 16) (BASE 0x0300) (CHECK))
-
-	   to this:
-
-	   (IO 0 (SIZE 16) (BASE 0x0340) )
-
-       e4.  if you have multiple Quicknet cards, make sure that you do
-            not have any overlaps.  Be especially careful if you are
-            mixing Internet PhoneJACK and Internet LineJACK cards in
-            the same system.  In these cases we recommend moving the
-            IO port addresses to the 0x400 block.  Please note that on
-            a few machines the 0x400 series are used.  Feel free to
-            experiment with other addresses.  Our cards have been
-            proven to work using IO addresses of up to 0xFF0.
-
-       e5.  the last step is to uncomment the activation line so the
-            drivers will be associated with the port.  This means the
-            line (immediately below) the IO line should go from this:
-
-            # (ACT Y)
-
-            to this:
-
-	    (ACT Y)
-
-            Once you have finished editing the isapnp.conf file you
-            must submit it into the pnp driverconfigure the cards.
-            This is done using the following command:
-
-	    isapnp isapnp.conf
-
-	    If this works you should see a line that identifies the
-            Quicknet device, the IO port(s) chosen, and a message
-            "Enabled OK".
-
-   f.  if you are loading the module by hand, use insmod.  An example
-of this would look like this:
-
-	insmod phonedev
-	insmod ixj dspio=0x320,0x310 xio=0,0x330
-
-Then verify the module loaded by running lsmod. If you are not using a
-module that matches your kernel version, you may need to "force" the
-load using the -f option in the insmod command.
-
-	insmod phonedev
-	insmod -f ixj dspio=0x320,0x310 xio=0,0x330
-
-
-If you are using isapnp to autoconfigure your card, then you do NOT
-need any of the above, though you need to use depmod to load the
-driver, like this:
-
-	depmod ixj
-
-which will result in the needed drivers getting loaded automatically.
-
-   g.  if you are planning on having the kernel automatically request
-the module for you, then you need to edit /etc/conf.modules and add the
-following lines:
-
-	options ixj dspio=0x340 xio=0x330 ixjdebug=0
-
-If you do this, then when you execute an application that uses the
-module the kernel will request that it is loaded.
-
-  h.  if you want non-root users to be able to read and write to the 
-ixj devices (this is a good idea!) you should do the following:
-
-     - decide upon a group name to use and create that group if 
-       needed.  Add the user names to that group that you wish to 
-       have access to the device.  For example, we typically will
-       create a group named "ixj" in /etc/group and add all users
-       to that group that we want to run software that can use the 
-       ixjX devices.
-
-     - change the permissions on the device files, like this:
-	
-       chgrp ixj /dev/ixj*	
-       chmod 660 /dev/ixj*
-	
-Once this is done, then non-root users should be able to use the
-devices.  If you have enabled autoloading of modules, then the user
-should be able to open the device and have the module loaded
-automatically for them.
-
-
-4.0 Driver Installation problems.
-
-We have tested these drivers on the 2.2.9, 2.2.10, 2.2.12, and 2.2.13 kernels
-and in all cases have eventually been able to get the drivers to load and 
-run.  We have found four types of problems that prevent this from happening.
-The problems and solutions are:
-
-  a. A step was missed in the installation.  Go back and use section 3
-as a checklist.  Many people miss running the ixj_dev_create script and thus
-never load the device names into the filesystem.
-
-  b. The kernel is inconsistently linked.  We have found this problem in
-the Out Of the Box installation of several distributions.  The symptoms 
-are that neither driver will load, and that the unknown symbols include "jiffy"
-and "kmalloc".  The solution is to recompile both the kernel and the
-modules.  The command string for the final compile looks like this:
-
-    In the kernel directory:
-    1.  cp .config /tmp
-    2.  make mrproper
-    3.  cp /tmp/.config .
-    4.	make clean;make bzImage;make modules;make modules_install
-
-This rebuilds both the kernel and all the modules and makes sure they all 
-have the same linkages.  This generally solves the problem once the new 
-kernel is installed and the system rebooted.
-
-  c. The kernel has been patched, then unpatched.  This happens when
-someone decides to use an earlier kernel after they load a later kernel.
-The symptoms are proceeding through all three above steps and still not
-being able to load the driver.  What has happened is that the generated
-header files are out of sync with the kernel itself.  The solution is
-to recompile (again) using "make mrproper".  This will remove and then
-regenerate all the necessary header files.  Once this is done, then you 
-need to install and reboot the kernel.  We have not seen any problem
-loading one of our drivers after this treatment.
-
-5.0  Known Limitations
-
-We cannot currently play "dial-tone" and listen for DTMF digits at the
-same time using the ISA PhoneJACK.  This is a bug in the 8020 DSP chip
-used on that product.  All other Quicknet products function normally
-in this regard.  We have a work-around, but it's not done yet.  Until
-then, if you want dial-tone, you can always play a recorded dial-tone
-sound into the audio until you have gathered the DTMF digits.

+内核提供的用户空间辅助代码
+=========================
+
+在内核内存空间的固定地址处，有一个由内核提供并可从用户空间访问的代码
+段。它用于向用户空间提供因在许多 ARM CPU 中未实现的特性和/或指令而需
+内核提供帮助的某些操作。这些代码直接在用户模式下执行的想法是为了获得
+最佳效率，但那些与内核计数器联系过于紧密的部分，则被留给了用户库实现。
+事实上，此代码甚至可能因不同的 CPU 而异，这取决于其可用的指令集或它
+是否为 SMP 系统。换句话说，内核保留在不作出警告的情况下根据需要更改
+这些代码的权利。只有本文档描述的入口及其结果是保证稳定的。
+
+这与完全成熟的 VDSO 实现不同（但两者并不冲突），尽管如此，VDSO 可阻止
+某些通过常量高效跳转到那些代码段的汇编技巧。且由于那些代码段在返回用户
+代码前仅使用少量的代码周期，则一个 VDSO 间接远程调用将会在这些简单的
+操作上增加一个可测量的开销。
+
+在对那些拥有原生支持的新型处理器进行代码优化时，仅在已为其他操作使用
+了类似的新增指令，而导致二进制结果已与早期 ARM 处理器不兼容的情况下，
+用户空间才应绕过这些辅助代码，并在内联函数中实现这些操作（无论是通过
+编译器在代码中直接放置，还是作为库函数调用实现的一部分）。也就是说，
+如果你编译的代码不会为了其他目的使用新指令，则不要仅为了避免使用这些
+内核辅助代码，导致二进制程序无法在早期处理器上运行。
+
+新的辅助代码可能随着时间的推移而增加，所以新内核中的某些辅助代码在旧
+内核中可能不存在。因此，程序必须在对任何辅助代码调用假设是安全之前，
+检测 __kuser_helper_version 的值（见下文）。理想情况下，这种检测应该
+只在进程启动时执行一次；如果内核版本不支持所需辅助代码，则该进程可尽早
+中止执行。
+
+kuser_helper_version
+--------------------
+
+位置:	0xffff0ffc
+
+参考声明:
+
+  extern int32_t __kuser_helper_version;
+
+定义:
+
+  这个区域包含了当前运行内核实现的辅助代码版本号。用户空间可以通过读
+  取此版本号以确定特定的辅助代码是否存在。
+
+使用范例:
+
+#define __kuser_helper_version (*(int32_t *)0xffff0ffc)
+
+void check_kuser_version(void)
+{
+	if (__kuser_helper_version < 2) {
+		fprintf(stderr, "can't do atomic operations, kernel too old\n");
+		abort();
+	}
+}
+
+注意:
+
+  用户空间可以假设这个域的值不会在任何单个进程的生存期内改变。也就
+  是说，这个域可以仅在库的初始化阶段或进程启动阶段读取一次。
+
+kuser_get_tls
+-------------
+
+位置:	0xffff0fe0
+
+参考原型:
+
+  void * __kuser_get_tls(void);
+
+输入:
+
+  lr = 返回地址
+
+输出:
+
+  r0 = TLS 值
+
+被篡改的寄存器:
+
+  无
+
+定义:
+
+  获取之前通过 __ARM_NR_set_tls 系统调用设置的 TLS 值。
+
+使用范例:
+
+typedef void * (__kuser_get_tls_t)(void);
+#define __kuser_get_tls (*(__kuser_get_tls_t *)0xffff0fe0)
+
+void foo()
+{
+	void *tls = __kuser_get_tls();
+	printf("TLS = %p\n", tls);
+}
+
+注意:
+
+  - 仅在 __kuser_helper_version >= 1 时，此辅助代码存在
+    （从内核版本 2.6.12 开始）。
+
+kuser_cmpxchg
+-------------
+
+位置:	0xffff0fc0
+
+参考原型:
+
+  int __kuser_cmpxchg(int32_t oldval, int32_t newval, volatile int32_t *ptr);
+
+输入:
+
+  r0 = oldval
+  r1 = newval
+  r2 = ptr
+  lr = 返回地址
+
+输出:
+
+  r0 = 成功代码 (零或非零)
+  C flag = 如果 r0 == 0 则置 1，如果 r0 != 0 则清零。
+
+被篡改的寄存器:
+
+  r3, ip, flags
+
+定义:
+
+  仅在 *ptr 为 oldval 时原子保存 newval 于 *ptr 中。
+  如果 *ptr 被改变，则返回值为零，否则为非零值。
+  如果 *ptr 被改变，则 C flag 也会被置 1，以实现调用代码中的汇编
+  优化。
+
+使用范例:
+
+typedef int (__kuser_cmpxchg_t)(int oldval, int newval, volatile int *ptr);
+#define __kuser_cmpxchg (*(__kuser_cmpxchg_t *)0xffff0fc0)
+
+int atomic_add(volatile int *ptr, int val)
+{
+	int old, new;
+
+	do {
+		old = *ptr;
+		new = old + val;
+	} while(__kuser_cmpxchg(old, new, ptr));
+
+	return new;
+}
+
+注意:
+
+  - 这个例程已根据需要包含了内存屏障。
+
+  - 仅在 __kuser_helper_version >= 2 时，此辅助代码存在
+    （从内核版本 2.6.12 开始）。
+
+kuser_memory_barrier
+--------------------
+
+位置:	0xffff0fa0
+
+参考原型:
+
+  void __kuser_memory_barrier(void);
+
+输入:
+
+  lr = 返回地址
+
+输出:
+
+  无
+
+被篡改的寄存器:
+
+  无
+
+定义:
+
+  应用于任何需要内存屏障以防止手动数据修改带来的一致性问题，以及
+  __kuser_cmpxchg 中。
+
+使用范例:
+
+typedef void (__kuser_dmb_t)(void);
+#define __kuser_dmb (*(__kuser_dmb_t *)0xffff0fa0)
+
+注意:
+
+  - 仅在 __kuser_helper_version >= 3 时，此辅助代码存在
+    （从内核版本 2.6.15 开始）。
+
+kuser_cmpxchg64
+---------------
+
+位置:	0xffff0f60
+
+参考原型:
+
+  int __kuser_cmpxchg64(const int64_t *oldval,
+                        const int64_t *newval,
+                        volatile int64_t *ptr);
+
+输入:
+
+  r0 = 指向 oldval
+  r1 = 指向 newval
+  r2 = 指向目标值
+  lr = 返回地址
+
+输出:
+
+  r0 = 成功代码 (零或非零)
+  C flag = 如果 r0 == 0 则置 1，如果 r0 != 0 则清零。
+
+被篡改的寄存器:
+
+  r3, lr, flags
+
+定义:
+
+  仅在 *ptr 等于 *oldval 指向的 64 位值时，原子保存 *newval
+  指向的 64 位值于 *ptr 中。如果 *ptr 被改变，则返回值为零，
+  否则为非零值。
+
+  如果 *ptr 被改变，则 C flag 也会被置 1，以实现调用代码中的汇编
+  优化。
+
+使用范例:
+
+typedef int (__kuser_cmpxchg64_t)(const int64_t *oldval,
+                                  const int64_t *newval,
+                                  volatile int64_t *ptr);
+#define __kuser_cmpxchg64 (*(__kuser_cmpxchg64_t *)0xffff0f60)
+
+int64_t atomic_add64(volatile int64_t *ptr, int64_t val)
+{
+	int64_t old, new;
+
+	do {
+		old = *ptr;
+		new = old + val;
+	} while(__kuser_cmpxchg64(&old, &new, ptr));
+
+	return new;
+}
+
+注意:
+
+  - 这个例程已根据需要包含了内存屏障。
+
+  - 由于这个过程的代码长度（此辅助代码跨越 2 个常规的 kuser “槽”），
+    因此 0xffff0f80 不被作为有效的入口点。
+
+  - 仅在 __kuser_helper_version >= 5 时，此辅助代码存在
+    （从内核版本 3.1 开始）。

-Configuration options - PC212E, PC214E, PC215E, PC218E, PC272E:
-  [0] - I/O port base address
-  [1] - IRQ (optional, but commands won't work without it)
-
-Configuration options - PCI215, PCI272:
-  [0] - PCI bus of device (optional)
-  [1] - PCI slot of device (optional)
-  If bus/slot is not specified, the first available PCI device will
-  be used.
-
-Passing a zero for an option is the same as leaving it unspecified.

-Each PPI is a 8255 chip providing 24 DIO channels.  The DIO channels
-are configurable as inputs or outputs in four groups:
-
-  Port A  - channels  0 to  7
-  Port B  - channels  8 to 15
-  Port CL - channels 16 to 19
-  Port CH - channels 20 to 23
-
-Only mode 0 of the 8255 chips is supported.
-
-Each CTR is a 8254 chip providing 3 16-bit counter channels.  Each
-channel is configured individually with INSN_CONFIG instructions.  The
-specific type of configuration instruction is specified in data[0].
-Some configuration instructions expect an additional parameter in
-data[1]; others return a value in data[1].  The following configuration
-instructions are supported:
-
-  INSN_CONFIG_SET_COUNTER_MODE.  Sets the counter channel's mode and
-    BCD/binary setting specified in data[1].
-
-  INSN_CONFIG_8254_READ_STATUS.  Reads the status register value for the
-    counter channel into data[1].
-
-  INSN_CONFIG_SET_CLOCK_SRC.  Sets the counter channel's clock source as
-    specified in data[1] (this is a hardware-specific value).  Not
-    supported on PC214E.  For the other boards, valid clock sources are
-    0 to 7 as follows:
-
-      0.  CLK n, the counter channel's dedicated CLK input from the SK1
-	connector.  (N.B. for other values, the counter channel's CLKn
-	pin on the SK1 connector is an output!)
-      1.  Internal 10 MHz clock.
-      2.  Internal 1 MHz clock.
-      3.  Internal 100 kHz clock.
-      4.  Internal 10 kHz clock.
-      5.  Internal 1 kHz clock.
-      6.  OUT n-1, the output of counter channel n-1 (see note 1 below).
-      7.  Ext Clock, the counter chip's dedicated Ext Clock input from
-	the SK1 connector.  This pin is shared by all three counter
-	channels on the chip.
-
-  INSN_CONFIG_GET_CLOCK_SRC.  Returns the counter channel's current
-    clock source in data[1].  For internal clock sources, data[2] is set
-    to the period in ns.
-
-  INSN_CONFIG_SET_GATE_SRC.  Sets the counter channel's gate source as
-    specified in data[2] (this is a hardware-specific value).  Not
-    supported on PC214E.  For the other boards, valid gate sources are 0
-    to 7 as follows:
-
-      0.  VCC (internal +5V d.c.), i.e. gate permanently enabled.
-      1.  GND (internal 0V d.c.), i.e. gate permanently disabled.
-      2.  GAT n, the counter channel's dedicated GAT input from the SK1
-	connector.  (N.B. for other values, the counter channel's GATn
-	pin on the SK1 connector is an output!)
-      3.  /OUT n-2, the inverted output of counter channel n-2 (see note
-	2 below).
-      4.  Reserved.
-      5.  Reserved.
-      6.  Reserved.
-      7.  Reserved.
-
-  INSN_CONFIG_GET_GATE_SRC.  Returns the counter channel's current gate
-    source in data[2].
-
-Clock and gate interconnection notes:
-
-  1.  Clock source OUT n-1 is the output of the preceding channel on the
-  same counter subdevice if n > 0, or the output of channel 2 on the
-  preceding counter subdevice (see note 3) if n = 0.
-
-  2.  Gate source /OUT n-2 is the inverted output of channel 0 on the
-  same counter subdevice if n = 2, or the inverted output of channel n+1
-  on the preceding counter subdevice (see note 3) if n < 2.
-
-  3.  The counter subdevices are connected in a ring, so the highest
-  counter subdevice precedes the lowest.
-
-The 'INTERRUPT' subdevice pretends to be a digital input subdevice.  The
-digital inputs come from the interrupt status register.  The number of
-channels matches the number of interrupt sources.  The PC214E does not
-have an interrupt status register; see notes on 'INTERRUPT SOURCES'
-below.

-When an interrupt source is enabled in the interrupt source enable
-register, a rising edge on the source signal latches the corresponding
-bit to 1 in the interrupt status register.
-
-When the interrupt status register value as a whole (actually, just the
-6 least significant bits) goes from zero to non-zero, the board will
-generate an interrupt.  For level-triggered hardware interrupts (PCI
-card), the interrupt will remain asserted until the interrupt status
-register is cleared to zero.  For edge-triggered hardware interrupts
-(ISA card), no further interrupts will occur until the interrupt status
-register is cleared to zero.  To clear a bit to zero in the interrupt
-status register, the corresponding interrupt source must be disabled
-in the interrupt source enable register (there is no separate interrupt
-clear register).
-
-The PC214E does not have an interrupt source enable register or an
-interrupt status register; its 'INTERRUPT' subdevice has a single
-channel and its interrupt source is selected by the position of jumper
-J5.
-
-COMMANDS
-
-The driver supports a read streaming acquisition command on the
-'INTERRUPT' subdevice.  The channel list selects the interrupt sources
-to be enabled.  All channels will be sampled together (convert_src ==
-TRIG_NOW).  The scan begins a short time after the hardware interrupt
-occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT,
-scan_begin_arg == 0).  The value read from the interrupt status register
-is packed into a short value, one bit per requested channel, in the
-order they appear in the channel list.

+ * Each PPI is a 8255 chip providing 24 DIO channels.  The DIO channels
+ * are configurable as inputs or outputs in four groups:
+ *
+ *   Port A  - channels  0 to  7
+ *   Port B  - channels  8 to 15
+ *   Port CL - channels 16 to 19
+ *   Port CH - channels 20 to 23
+ *
+ * Only mode 0 of the 8255 chips is supported.
+ *
+ * Each CTR is a 8254 chip providing 3 16-bit counter channels.  Each
+ * channel is configured individually with INSN_CONFIG instructions.  The
+ * specific type of configuration instruction is specified in data[0].
+ * Some configuration instructions expect an additional parameter in
+ * data[1]; others return a value in data[1].  The following configuration
+ * instructions are supported:
+ *
+ *   INSN_CONFIG_SET_COUNTER_MODE.  Sets the counter channel's mode and
+ *     BCD/binary setting specified in data[1].
+ *
+ *   INSN_CONFIG_8254_READ_STATUS.  Reads the status register value for the
+ *     counter channel into data[1].
+ *
+ *   INSN_CONFIG_SET_CLOCK_SRC.  Sets the counter channel's clock source as
+ *     specified in data[1] (this is a hardware-specific value).  Not
+ *     supported on PC214E.  For the other boards, valid clock sources are
+ *     0 to 7 as follows:
+ *
+ *       0.  CLK n, the counter channel's dedicated CLK input from the SK1
+ *         connector.  (N.B. for other values, the counter channel's CLKn
+ *         pin on the SK1 connector is an output!)
+ *       1.  Internal 10 MHz clock.
+ *       2.  Internal 1 MHz clock.
+ *       3.  Internal 100 kHz clock.
+ *       4.  Internal 10 kHz clock.
+ *       5.  Internal 1 kHz clock.
+ *       6.  OUT n-1, the output of counter channel n-1 (see note 1 below).
+ *       7.  Ext Clock, the counter chip's dedicated Ext Clock input from
+ *         the SK1 connector.  This pin is shared by all three counter
+ *         channels on the chip.
+ *
+ *     For the PCIe boards, clock sources in the range 0 to 31 are allowed
+ *     and the following additional clock sources are defined:
+ *
+ *       8.  HIGH logic level.
+ *       9.  LOW logic level.
+ *      10.  "Pattern present" signal.
+ *      11.  Internal 20 MHz clock.
+ *
+ *   INSN_CONFIG_GET_CLOCK_SRC.  Returns the counter channel's current
+ *     clock source in data[1].  For internal clock sources, data[2] is set
+ *     to the period in ns.
+ *
+ *   INSN_CONFIG_SET_GATE_SRC.  Sets the counter channel's gate source as
+ *     specified in data[2] (this is a hardware-specific value).  Not
+ *     supported on PC214E.  For the other boards, valid gate sources are 0
+ *     to 7 as follows:
+ *
+ *       0.  VCC (internal +5V d.c.), i.e. gate permanently enabled.
+ *       1.  GND (internal 0V d.c.), i.e. gate permanently disabled.
+ *       2.  GAT n, the counter channel's dedicated GAT input from the SK1
+ *         connector.  (N.B. for other values, the counter channel's GATn
+ *         pin on the SK1 connector is an output!)
+ *       3.  /OUT n-2, the inverted output of counter channel n-2 (see note
+ *         2 below).
+ *       4.  Reserved.
+ *       5.  Reserved.
+ *       6.  Reserved.
+ *       7.  Reserved.
+ *
+ *     For the PCIe boards, gate sources in the range 0 to 31 are allowed;
+ *     the following additional clock sources and clock sources 6 and 7 are
+ *     (re)defined:
+ *
+ *       6.  /GAT n, negated version of the counter channel's dedicated
+ *         GAT input (negated version of gate source 2).
+ *       7.  OUT n-2, the non-inverted output of counter channel n-2
+ *         (negated version of gate source 3).
+ *       8.  "Pattern present" signal, HIGH while pattern present.
+ *       9.  "Pattern occurred" latched signal, latches HIGH when pattern
+ *         occurs.
+ *      10.  "Pattern gone away" latched signal, latches LOW when pattern
+ *         goes away after it occurred.
+ *      11.  Negated "pattern present" signal, LOW while pattern present
+ *         (negated version of gate source 8).
+ *      12.  Negated "pattern occurred" latched signal, latches LOW when
+ *         pattern occurs (negated version of gate source 9).
+ *      13.  Negated "pattern gone away" latched signal, latches LOW when
+ *         pattern goes away after it occurred (negated version of gate
+ *         source 10).
+ *
+ *   INSN_CONFIG_GET_GATE_SRC.  Returns the counter channel's current gate
+ *     source in data[2].
+ *
+ * Clock and gate interconnection notes:
+ *
+ *   1.  Clock source OUT n-1 is the output of the preceding channel on the
+ *   same counter subdevice if n > 0, or the output of channel 2 on the
+ *   preceding counter subdevice (see note 3) if n = 0.
+ *
+ *   2.  Gate source /OUT n-2 is the inverted output of channel 0 on the
+ *   same counter subdevice if n = 2, or the inverted output of channel n+1
+ *   on the preceding counter subdevice (see note 3) if n < 2.
+ *
+ *   3.  The counter subdevices are connected in a ring, so the highest
+ *   counter subdevice precedes the lowest.
+ *
+ * The 'TIMER' subdevice is a free-running 32-bit timer subdevice.
+ *
+ * The 'INTERRUPT' subdevice pretends to be a digital input subdevice.  The
+ * digital inputs come from the interrupt status register.  The number of
+ * channels matches the number of interrupt sources.  The PC214E does not
+ * have an interrupt status register; see notes on 'INTERRUPT SOURCES'
+ * below.

-    NAME
-        CsrLogLevelTextSet
-
-    DESCRIPTION
-        Set the text logging level for a given origin and optionally sub origin
-        by name. If either string is NULL or zero length, it is interpreted as
-        all origins and/or all sub origins respectively. If originName is NULL
-        or zero length, subOriginName is ignored.
-
-        Passing NULL or zero length strings in both originName and subOriginName
-        is equivalent to calling CsrLogLevelTextSetAll, and overrides all
-        previous filter configurations for all origins and sub origins.
-
-        Passing NULL or a zero length string in subOriginName overrides all
-        previous filter configurations for all sub origins of the specified
-        origin.
-
-        Note: the supplied strings may be accessed after the function returns
-        and must remain valid and constant until CsrLogDeinit is called.
-
-        Note: when specifying an origin (originName is not NULL and not zero
-        length), this function can only be used for origins that use the
-        csr_log_text_2.h interface for registration and logging. Filtering for
-        origins that use the legacy csr_log_text.h interface must be be
-        configured using the legacy filter configuration functions that accept
-        a CsrLogTextTaskId as origin specifier. However, when not specifying an
-        origin this function also affects origins that have been registered with
-        the legacy csr_log_text.h interface. Furthermore, using this function
-        and the legacy filter configuration functions on the same origin is not
-        allowed.
-
-    PARAMETERS
-        originName - a string containing the name of the origin. Can be NULL or
-            zero length to set the log level for all origins. In this case, the
-            subOriginName parameter will be ignored.
-        subOriginName - a string containing the name of the sub origin. Can be
-            NULL or zero length to set the log level for all sub origins of the
-            specified origin.
-        warningLevelMask - The desired log level for the specified origin(s) and
-            sub origin(s).

-    DESCRIPTION
-        Type to hold a value describing the current system time, which is a
-        measure of time elapsed since some arbitrarily defined fixed time
-        reference, usually associated with system startup.
+DESCRIPTION
+	Returns the current system time in a low and a high part. The low part
+	is expressed in microseconds. The high part is incremented when the low
+	part wraps to provide an extended range.
+
+	The caller may provide a NULL pointer as the high parameter.
+	In this case the function just returns the low part and ignores the
+	high parameter.
+
+	Although the time is expressed in microseconds the actual resolution is
+	platform dependent and can be less. It is recommended that the
+	resolution is at least 10 milliseconds.
+
+PARAMETERS
+	high - Pointer to variable that will receive the high part of the
+	       current system time. Passing NULL is valid.

+TODOs
+-----
+1. Implement retries for RCODE_BUSY, RCODE_NO_ACK and RCODE_SEND_ERROR
+   - I/O is handled asynchronously which presents some issues when error
+     conditions occur.
+2. Implement _robust_ console on top of this. The existing prototype console
+   driver is not ready for the big leagues yet.
+3. Expose means of controlling attach/detach of peers via sysfs. Include
+   GUID-to-port matching/whitelist/blacklist.
+
+-- Issues with firewire stack --
+1. This driver uses the same unregistered vendor id that the firewire core does
+     (0xd00d1e). Perhaps this could be exposed as a define in
+     firewire-constants.h?
+2. MAX_ASYNC_PAYLOAD needs to be publicly exposed by core/ohci
+   - otherwise how will this driver know the max size of address window to
+     open for one packet write?
+3. Maybe device_max_receive() and link_speed_to_max_payload() should be
+     taken up by the firewire core?
+4. To avoid dropping rx data while still limiting the maximum buffering,
+     the size of the AR context must be known. How to expose this to drivers?
+5. Explore if bigger AR context will reduce RCODE_BUSY responses
+   (or auto-grow to certain max size -- but this would require major surgery
+    as the current AR is contiguously mapped)
+
+-- Issues with TTY core --
+  1. Hack for alternate device name scheme
+     - because udev no longer allows device renaming, devices should have
+       their proper names on creation. This is an issue for creating the
+       fwloop<n> device with the fwtty<n> devices because although duplicating
+       roughly the same operations as tty_port_register_device() isn't difficult,
+       access to the tty_class & tty_fops is restricted in scope.
+
+       This is currently being worked around in create_loop_device() by
+       extracting the tty_class ptr and tty_fops ptr from the previously created
+       tty devices. Perhaps an add'l api can be added -- eg.,
+       tty_{port_}register_named_device().

+/**
+ * The design basis for the DMA FIFO is to provide an output side that
+ * complies with the streaming DMA API design that can be DMA'd from directly
+ * (without additional copying), coupled with an input side that maintains a
+ * logically consistent 'apparent' size (ie, bytes in + bytes avail is static
+ * for the lifetime of the FIFO).
+ *
+ * DMA output transactions originate on a cache line boundary and can be
+ * variably-sized. DMA output transactions can be retired out-of-order but
+ * the FIFO will only advance the output in the original input sequence.
+ * This means the FIFO will eventually stall if a transaction is never retired.
+ *
+ * Chunking the output side into cache line multiples means that some FIFO
+ * memory is unused. For example, if all the avail input has been pended out,
+ * then the in and out markers are re-aligned to the next cache line.
+ * The maximum possible waste is
+ *     (cache line alignment - 1) * (max outstanding dma transactions)
+ * This potential waste requires additional hidden capacity within the FIFO
+ * to be able to accept input while the 'apparent' size has not been reached.
+ *
+ * Additional cache lines (ie, guard area) are used to minimize DMA
+ * fragmentation when wrapping at the end of the FIFO. Input is allowed into the
+ * guard area, but the in and out FIFO markers are wrapped when DMA is pended.

+ * fwserial_probe: bus probe function for firewire 'serial' unit devices
+ *
+ * A 'serial' unit device is created and probed as a result of:
+ * - declaring a ieee1394 bus id table for 'devices' matching a fabricated
+ *   'serial' unit specifier id
+ * - adding a unit directory to the config ROM(s) for a 'serial' unit
+ *
+ * The firewire core registers unit devices by enumerating unit directories
+ * of a node's config ROM after reading the config ROM when a new node is
+ * added to the bus topology after a bus reset.
+ *
+ * The practical implications of this are:
+ * - this probe is called for both local and remote nodes that have a 'serial'
+ *   unit directory in their config ROM (that matches the specifiers in
+ *   fwserial_id_table).
+ * - no specific order is enforced for local vs. remote unit devices
+ *
+ * This unit driver copes with the lack of specific order in the same way the
+ * firewire net driver does -- each probe, for either a local or remote unit
+ * device, is treated as a 'peer' (has a struct fwtty_peer instance) and the
+ * first peer created for a given fw_card (tracked by the global fwserial_list)
+ * creates the underlying TTYs (aggregated in a fw_serial instance).
+ *
+ * NB: an early attempt to differentiate local & remote unit devices by creating
+ *     peers only for remote units and fw_serial instances (with their
+ *     associated TTY devices) only for local units was discarded. Managing
+ *     the peer lifetimes on device removal proved too complicated.
+ *
+ * fwserial_probe/fwserial_remove are effectively serialized by the
+ * fwserial_list_mutex. This is necessary because the addition of the first peer
+ * for a given fw_card will trigger the creation of the fw_serial for that
+ * fw_card, which must not simultaneously contend with the removal of the
+ * last peer for a given fw_card triggering the destruction of the same
+ * fw_serial for the same fw_card.

+ *
+ * Once data bits are pushed out, controller raises the Tx-room-avail-Interrupt.
+ * The first thing Tx ISR does is disable further Tx interrupts (as this could
+ * be the last char to send, before settling down into the quiet polled mode).
+ * It then calls the exact routine used by tty layer write to send out any
+ * more char in tty buffer. In case of sending, it re-enables Tx-intr. In case

- * The File-backed Storage Gadget acts as a USB Mass Storage device,
- * appearing to the host as a disk drive or as a CD-ROM drive.  In addition
- * to providing an example of a genuinely useful gadget driver for a USB
- * device, it also illustrates a technique of double-buffering for increased
- * throughput.  Last but not least, it gives an easy way to probe the
- * behavior of the Mass Storage drivers in a USB host.
- *
- * Backing storage is provided by a regular file or a block device, specified
- * by the "file" module parameter.  Access can be limited to read-only by
- * setting the optional "ro" module parameter.  (For CD-ROM emulation,
- * access is always read-only.)  The gadget will indicate that it has
- * removable media if the optional "removable" module parameter is set.
- *
- * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
- * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
- * by the optional "transport" module parameter.  It also supports the
- * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
- * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
- * the optional "protocol" module parameter.  In addition, the default
- * Vendor ID, Product ID, release number and serial number can be overridden.
- *
- * There is support for multiple logical units (LUNs), each of which has
- * its own backing file.  The number of LUNs can be set using the optional
- * "luns" module parameter (anywhere from 1 to 8), and the corresponding
- * files are specified using comma-separated lists for "file" and "ro".
- * The default number of LUNs is taken from the number of "file" elements;
- * it is 1 if "file" is not given.  If "removable" is not set then a backing
- * file must be specified for each LUN.  If it is set, then an unspecified
- * or empty backing filename means the LUN's medium is not loaded.  Ideally
- * each LUN would be settable independently as a disk drive or a CD-ROM
- * drive, but currently all LUNs have to be the same type.  The CD-ROM
- * emulation includes a single data track and no audio tracks; hence there
- * need be only one backing file per LUN.
- *
- * Requirements are modest; only a bulk-in and a bulk-out endpoint are
- * needed (an interrupt-out endpoint is also needed for CBI).  The memory
- * requirement amounts to two 16K buffers, size configurable by a parameter.
- * Support is included for both full-speed and high-speed operation.
- *
- * Note that the driver is slightly non-portable in that it assumes a
- * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
- * interrupt-in endpoints.  With most device controllers this isn't an
- * issue, but there may be some with hardware restrictions that prevent
- * a buffer from being used by more than one endpoint.
- *
- * Module options:
- *
- *	file=filename[,filename...]
- *				Required if "removable" is not set, names of
- *					the files or block devices used for
- *					backing storage
- *	serial=HHHH...		Required serial number (string of hex chars)
- *	ro=b[,b...]		Default false, booleans for read-only access
- *	removable		Default false, boolean for removable media
- *	luns=N			Default N = number of filenames, number of
- *					LUNs to support
- *	nofua=b[,b...]		Default false, booleans for ignore FUA flag
- *					in SCSI WRITE(10,12) commands
- *	stall			Default determined according to the type of
- *					USB device controller (usually true),
- *					boolean to permit the driver to halt
- *					bulk endpoints
- *	cdrom			Default false, boolean for whether to emulate
- *					a CD-ROM drive
- *	transport=XXX		Default BBB, transport name (CB, CBI, or BBB)
- *	protocol=YYY		Default SCSI, protocol name (RBC, 8020 or
- *					ATAPI, QIC, UFI, 8070, or SCSI;
- *					also 1 - 6)
- *	vendor=0xVVVV		Default 0x0525 (NetChip), USB Vendor ID
- *	product=0xPPPP		Default 0xa4a5 (FSG), USB Product ID
- *	release=0xRRRR		Override the USB release number (bcdDevice)
- *	buflen=N		Default N=16384, buffer size used (will be
- *					rounded down to a multiple of
- *					PAGE_CACHE_SIZE)
- *
- * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro",
- * "removable", "luns", "nofua", "stall", and "cdrom" options are available;
- * default values are used for everything else.
- *
- * The pathnames of the backing files and the ro settings are available in
- * the attribute files "file", "nofua", and "ro" in the lun<n> subdirectory of
- * the gadget's sysfs directory.  If the "removable" option is set, writing to
- * these files will simulate ejecting/loading the medium (writing an empty
- * line means eject) and adjusting a write-enable tab.  Changes to the ro
- * setting are not allowed when the medium is loaded or if CD-ROM emulation
- * is being used.
- *
- * This gadget driver is heavily based on "Gadget Zero" by David Brownell.
- * The driver's SCSI command interface was based on the "Information
- * technology - Small Computer System Interface - 2" document from
- * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at
- * <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.  The single exception
- * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the
- * "Universal Serial Bus Mass Storage Class UFI Command Specification"
- * document, Revision 1.0, December 14, 1998, available at
- * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

-/*
- *				Driver Design
- *
- * The FSG driver is fairly straightforward.  There is a main kernel
- * thread that handles most of the work.  Interrupt routines field
- * callbacks from the controller driver: bulk- and interrupt-request
- * completion notifications, endpoint-0 events, and disconnect events.
- * Completion events are passed to the main thread by wakeup calls.  Many
- * ep0 requests are handled at interrupt time, but SetInterface,
- * SetConfiguration, and device reset requests are forwarded to the
- * thread in the form of "exceptions" using SIGUSR1 signals (since they
- * should interrupt any ongoing file I/O operations).
- *
- * The thread's main routine implements the standard command/data/status
- * parts of a SCSI interaction.  It and its subroutines are full of tests
- * for pending signals/exceptions -- all this polling is necessary since
- * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
- * indication that the driver really wants to be running in userspace.)
- * An important point is that so long as the thread is alive it keeps an
- * open reference to the backing file.  This will prevent unmounting
- * the backing file's underlying filesystem and could cause problems
- * during system shutdown, for example.  To prevent such problems, the
- * thread catches INT, TERM, and KILL signals and converts them into
- * an EXIT exception.
- *
- * In normal operation the main thread is started during the gadget's
- * fsg_bind() callback and stopped during fsg_unbind().  But it can also
- * exit when it receives a signal, and there's no point leaving the
- * gadget running when the thread is dead.  So just before the thread
- * exits, it deregisters the gadget driver.  This makes things a little
- * tricky: The driver is deregistered at two places, and the exiting
- * thread can indirectly call fsg_unbind() which in turn can tell the
- * thread to exit.  The first problem is resolved through the use of the
- * REGISTERED atomic bitflag; the driver will only be deregistered once.
- * The second problem is resolved by having fsg_unbind() check
- * fsg->state; it won't try to stop the thread if the state is already
- * FSG_STATE_TERMINATED.
- *
- * To provide maximum throughput, the driver uses a circular pipeline of
- * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
- * arbitrarily long; in practice the benefits don't justify having more
- * than 2 stages (i.e., double buffering).  But it helps to think of the
- * pipeline as being a long one.  Each buffer head contains a bulk-in and
- * a bulk-out request pointer (since the buffer can be used for both
- * output and input -- directions always are given from the host's
- * point of view) as well as a pointer to the buffer and various state
- * variables.
- *
- * Use of the pipeline follows a simple protocol.  There is a variable
- * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
- * At any time that buffer head may still be in use from an earlier
- * request, so each buffer head has a state variable indicating whether
- * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
- * buffer head to be EMPTY, filling the buffer either by file I/O or by
- * USB I/O (during which the buffer head is BUSY), and marking the buffer
- * head FULL when the I/O is complete.  Then the buffer will be emptied
- * (again possibly by USB I/O, during which it is marked BUSY) and
- * finally marked EMPTY again (possibly by a completion routine).
- *
- * A module parameter tells the driver to avoid stalling the bulk
- * endpoints wherever the transport specification allows.  This is
- * necessary for some UDCs like the SuperH, which cannot reliably clear a
- * halt on a bulk endpoint.  However, under certain circumstances the
- * Bulk-only specification requires a stall.  In such cases the driver
- * will halt the endpoint and set a flag indicating that it should clear
- * the halt in software during the next device reset.  Hopefully this
- * will permit everything to work correctly.  Furthermore, although the
- * specification allows the bulk-out endpoint to halt when the host sends
- * too much data, implementing this would cause an unavoidable race.
- * The driver will always use the "no-stall" approach for OUT transfers.
- *
- * One subtle point concerns sending status-stage responses for ep0
- * requests.  Some of these requests, such as device reset, can involve
- * interrupting an ongoing file I/O operation, which might take an
- * arbitrarily long time.  During that delay the host might give up on
- * the original ep0 request and issue a new one.  When that happens the
- * driver should not notify the host about completion of the original
- * request, as the host will no longer be waiting for it.  So the driver
- * assigns to each ep0 request a unique tag, and it keeps track of the
- * tag value of the request associated with a long-running exception
- * (device-reset, interface-change, or configuration-change).  When the
- * exception handler is finished, the status-stage response is submitted
- * only if the current ep0 request tag is equal to the exception request
- * tag.  Thus only the most recently received ep0 request will get a
- * status-stage response.
- *
- * Warning: This driver source file is too long.  It ought to be split up
- * into a header file plus about 3 separate .c files, to handle the details
- * of the Gadget, USB Mass Storage, and SCSI protocols.

- * selected during submission.  Otherwise drivers must specify the start_frame

+ * If an isochronous endpoint queue isn't already running, the host
+ * controller will schedule a new URB to start as soon as bandwidth
+ * utilization allows.  If the queue is running then a new URB will be
+ * scheduled to start in the first transfer slot following the end of the
+ * preceding URB, if that slot has not already expired.  If the slot has
+ * expired (which can happen when IRQ delivery is delayed for a long time),
+ * the scheduling behavior depends on the URB_ISO_ASAP flag.  If the flag
+ * is clear then the URB will be scheduled to start in the expired slot,
+ * implying that some of its packets will not be transferred; if the flag
+ * is set then the URB will be scheduled in the first unexpired slot,
+ * breaking the queue's synchronization.  Upon URB completion, the
