+
+
+1. Blackfin GPIO introduction
+
+    There are many GPIO pins on Blackfin. Most of these pins are muxed to
+    multi-functions. They can be configured as peripheral, or just as GPIO,
+    configured to input with interrupt enabled, or output.
+
+    For detailed information, please see "arch/blackfin/kernel/bfin_gpio.c",
+    or the relevant HRM.
+
+
+2. Avoiding resource conflict
+
+    Followed function groups are used to avoiding resource conflict,
+    - Use the pin as peripheral,
+	int peripheral_request(unsigned short per, const char *label);
+	int peripheral_request_list(const unsigned short per[], const char *label);
+	void peripheral_free(unsigned short per);
+	void peripheral_free_list(const unsigned short per[]);
+    - Use the pin as GPIO,
+	int bfin_gpio_request(unsigned gpio, const char *label);
+	void bfin_gpio_free(unsigned gpio);
+    - Use the pin as GPIO interrupt,
+	int bfin_gpio_irq_request(unsigned gpio, const char *label);
+	void bfin_gpio_irq_free(unsigned gpio);
+
+    The request functions will record the function state for a certain pin,
+    the free functions will clear it's function state.
+    Once a pin is requested, it can't be requested again before it is freed by
+    previous caller, otherwise kernel will dump stacks, and the request
+    function fail.
+    These functions are wrapped by other functions, most of the users need not
+    care.
+
+
+3. But there are some exceptions
+    - Kernel permit the identical GPIO be requested both as GPIO and GPIO
+    interrut.
+    Some drivers, like gpio-keys, need this behavior. Kernel only print out
+    warning messages like,
+	bfin-gpio: GPIO 24 is already reserved by gpio-keys: BTN0, and you are
+configuring it as IRQ!
+
+        Note: Consider the case that, if there are two drivers need the
+	identical GPIO, one of them use it as GPIO, the other use it as
+	GPIO interrupt. This will really cause resource conflict. So if
+	there is any abnormal driver behavior, please check the bfin-gpio
+	warning messages.
+
+    - Kernel permit the identical GPIO be requested from the same driver twice.

+
+To support containers, we now allow multiple instances of devpts filesystem,
+such that indices of ptys allocated in one instance are independent of indices
+allocated in other instances of devpts.
+
+To preserve backward compatibility, this support for multiple instances is
+enabled only if:
+
+	- CONFIG_DEVPTS_MULTIPLE_INSTANCES=y, and
+	- '-o newinstance' mount option is specified while mounting devpts
+
+IOW, devpts now supports both single-instance and multi-instance semantics.
+
+If CONFIG_DEVPTS_MULTIPLE_INSTANCES=n, there is no change in behavior and
+this referred to as the "legacy" mode. In this mode, the new mount options
+(-o newinstance and -o ptmxmode) will be ignored with a 'bogus option' message
+on console.
+
+If CONFIG_DEVPTS_MULTIPLE_INSTANCES=y and devpts is mounted without the
+'newinstance' option (as in current start-up scripts) the new mount binds
+to the initial kernel mount of devpts. This mode is referred to as the
+'single-instance' mode and the current, single-instance semantics are
+preserved, i.e PTYs are common across the system.
+
+The only difference between this single-instance mode and the legacy mode
+is the presence of new, '/dev/pts/ptmx' node with permissions 0000, which
+can safely be ignored.
+
+If CONFIG_DEVPTS_MULTIPLE_INSTANCES=y and 'newinstance' option is specified,
+the mount is considered to be in the multi-instance mode and a new instance
+of the devpts fs is created. Any ptys created in this instance are independent
+of ptys in other instances of devpts. Like in the single-instance mode, the
+/dev/pts/ptmx node is present. To effectively use the multi-instance mode,
+open of /dev/ptmx must be a redirected to '/dev/pts/ptmx' using a symlink or
+bind-mount.
+
+Eg: A container startup script could do the following:
+
+	$ chmod 0666 /dev/pts/ptmx
+	$ rm /dev/ptmx
+	$ ln -s pts/ptmx /dev/ptmx
+	$ ns_exec -cm /bin/bash
+
+	# We are now in new container
+
+	$ umount /dev/pts
+	$ mount -t devpts -o newinstance lxcpts /dev/pts
+	$ sshd -p 1234
+
+where 'ns_exec -cm /bin/bash' calls clone() with CLONE_NEWNS flag and execs
+/bin/bash in the child process.  A pty created by the sshd is not visible in
+the original mount of /dev/pts.
+
+User-space changes
+------------------
+
+In multi-instance mode (i.e '-o newinstance' mount option is specified at least
+once), following user-space issues should be noted.
+
+1. If -o newinstance mount option is never used, /dev/pts/ptmx can be ignored
+   and no change is needed to system-startup scripts.
+
+2. To effectively use multi-instance mode (i.e -o newinstance is specified)
+   administrators or startup scripts should "redirect" open of /dev/ptmx to
+   /dev/pts/ptmx using either a bind mount or symlink.
+
+	$ mount -t devpts -o newinstance devpts /dev/pts
+
+   followed by either
+
+	$ rm /dev/ptmx
+	$ ln -s pts/ptmx /dev/ptmx
+	$ chmod 666 /dev/pts/ptmx
+   or
+	$ mount -o bind /dev/pts/ptmx /dev/ptmx
+
+3. The '/dev/ptmx -> pts/ptmx' symlink is the preferred method since it
+   enables better error-reporting and treats both single-instance and
+   multi-instance mounts similarly.
+
+   But this method requires that system-startup scripts set the mode of
+   /dev/pts/ptmx correctly (default mode is 0000). The scripts can set the
+   mode by, either
+
+   	- adding ptmxmode mount option to devpts entry in /etc/fstab, or
+	- using 'chmod 0666 /dev/pts/ptmx'
+
+4. If multi-instance mode mount is needed for containers, but the system
+   startup scripts have not yet been updated, container-startup scripts
+   should bind mount /dev/ptmx to /dev/pts/ptmx to avoid breaking single-
+   instance mounts.
+
+   Or, in general, container-startup scripts should use:
+
+	mount -t devpts -o newinstance -o ptmxmode=0666 devpts /dev/pts
+	if [ ! -L /dev/ptmx ]; then
+		mount -o bind /dev/pts/ptmx /dev/ptmx
+	fi
+
+   When all devpts mounts are multi-instance, /dev/ptmx can permanently be
+   a symlink to pts/ptmx and the bind mount can be ignored.
+
+5. A multi-instance mount that is not accompanied by the /dev/ptmx to
+   /dev/pts/ptmx redirection would result in an unusable/unreachable pty.
+
+	mount -t devpts -o newinstance lxcpts /dev/pts
+
+   immediately followed by:
+
+	open("/dev/ptmx")
+
+    would create a pty, say /dev/pts/7, in the initial kernel mount.
+    But /dev/pts/7 would be invisible in the new mount.
+
+6. The permissions for /dev/pts/ptmx node should be specified when mounting
+   /dev/pts, using the '-o ptmxmode=%o' mount option (default is 0000).
+
+	mount -t devpts -o newinstance -o ptmxmode=0644 devpts /dev/pts
+
+   The permissions can be later be changed as usual with 'chmod'.
+
+	chmod 666 /dev/pts/ptmx
+
+7. A mount of devpts without the 'newinstance' option results in binding to
+   initial kernel mount.  This behavior while preserving legacy semantics,
+   does not provide strict isolation in a container environment. i.e by
+   mounting devpts without the 'newinstance' option, a container could
+   get visibility into the 'host' or root container's devpts.
+   
+   To workaround this and have strict isolation, all mounts of devpts,
+   including the mount in the root container, should use the newinstance
+   option.

+Description
+-----------
+
+Fintek F718xxFG/F8000 Super I/O chips include complete hardware monitoring
+capabilities. They can monitor up to 9 voltages (3 for the F8000), 4 fans and
+3 temperature sensors.
+
+These chips also have fan controlling features, using either DC or PWM, in
+three different modes (one manual, two automatic).
+
+The driver assumes that no more than one chip is present, which seems
+reasonable.
+
+
+Monitoring
+----------
+
+The Voltage, Fan and Temperature Monitoring uses the standard sysfs
+interface as documented in sysfs-interface, without any exceptions.
+
+
+Fan Control
+-----------
+
+Both PWM (pulse-width modulation) and DC fan speed control methods are
+supported. The right one to use depends on external circuitry on the
+motherboard, so the driver assumes that the BIOS set the method
+properly.
+
+There are 2 modes to specify the speed of the fan, PWM duty cycle (or DC
+voltage) mode, where 0-100% duty cycle (0-100% of 12V) is specified. And RPM
+mode where the actual RPM of the fan (as measured) is controlled and the speed
+gets specified as 0-100% of the fan#_full_speed file.
+
+Since both modes work in a 0-100% (mapped to 0-255) scale, there isn't a
+whole lot of a difference when modifying fan control settings. The only
+important difference is that in RPM mode the 0-100% controls the fan speed
+between 0-100% of fan#_full_speed. It is assumed that if the BIOS programs
+RPM mode, it will also set fan#_full_speed properly, if it does not then
+fan control will not work properly, unless you set a sane fan#_full_speed
+value yourself.
+
+Switching between these modes requires re-initializing a whole bunch of
+registers, so the mode which the BIOS has set is kept. The mode is
+printed when loading the driver.
+
+Three different fan control modes are supported; the mode number is written
+to the pwm#_enable file. Note that not all modes are supported on all
+chips, and some modes may only be available in RPM / PWM mode on the F8000.
+Writing an unsupported mode will result in an invalid parameter error.
+
+* 1: Manual mode
+  You ask for a specific PWM duty cycle / DC voltage or a specific % of
+  fan#_full_speed by writing to the pwm# file. This mode is only
+  available on the F8000 if the fan channel is in RPM mode.
+
+* 2: Normal auto mode
+  You can define a number of temperature/fan speed trip points, which % the
+  fan should run at at this temp and which temp a fan should follow using the
+  standard sysfs interface. The number and type of trip points is chip
+  depended, see which files are available in sysfs.
+  Fan/PWM channel 3 of the F8000 is always in this mode!
+
+* 3: Thermostat mode (Only available on the F8000 when in duty cycle mode)
+  The fan speed is regulated to keep the temp the fan is mapped to between
+  temp#_auto_point2_temp and temp#_auto_point3_temp.
+
+Both of the automatic modes require that pwm1 corresponds to fan1, pwm2 to
+fan2 and pwm3 to fan3.

+The LTC4245 controller allows a board to be safely inserted and removed
+from a live backplane in multiple supply systems such as CompactPCI and
+PCI Express.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for LTC4245 devices, due to the fact that some
+of the possible addresses are unfriendly to probing. You will need to use
+the "force" parameter to tell the driver where to find the device.
+
+Example: the following will load the driver for an LTC4245 at address 0x23
+on I2C bus #1:
+$ modprobe ltc4245 force=1,0x23
+
+
+Sysfs entries
+-------------
+
+The LTC4245 has built-in limits for over and under current warnings. This
+makes it very likely that the reference circuit will be used.
+
+This driver uses the values in the datasheet to change the register values
+into the values specified in the sysfs-interface document. The current readings

+first ten nibbles.
+
+Next nibbles 12 .. 21 represents four channels (not all channels can be
+directly controlled from TX). Binary representations ar the same as in first
+four channels. In nibbles 22 and 23 is a special magic number. Nibble 24 is
+checksum for nibbles 12..23.
+
+After last octal value for nibble 24 and next sync pulse one additional
+binary value can be sampled. This bit and magic number is not used in
+software driver. Some details about this magic numbers can be found in
+Walkera_Wk-0701_PCM.pdf.
+
+Checksum calculation:
+
+Summary of octal values in nibbles must be same as octal value in checksum
+nibble (only first 3 bits are used). Binary value for checksum nibble is
+calculated by sum of binary values in checked nibbles + sum of octal values
+in checked nibbles divided by 8. Only bit 0 of this sum is used.

+In most cases the name of the architecture is the same as the
+directory name found in the arch/ directory.
+But some architectures suach as x86 and sparc has aliases.
+x86: i386 for 32 bit, x86_64 for 64 bit
+sparc: sparc for 32 bit, sparc64 for 64 bit
+
+CROSS_COMPILE

+relocations required by build roots.  This is not defined in the
+makefile but the argument can be passed to make if needed.
+
+INSTALL_MOD_STRIP
+--------------------------------------------------
+INSTALL_MOD_STRIP, if defined, will cause modules to be
+stripped after they are installed.  If INSTALL_MOD_STRIP is '1', then

+This file contains some assistance for using "make *config".
+
+Use "make help" to list all of the possible configuration targets.
+
+The xconfig ('qconf') and menuconfig ('mconf') programs also
+have embedded help text.  Be sure to check it for navigation,
+search, and other general help text.
+
+======================================================================
+General
+--------------------------------------------------
+
+New kernel releases often introduce new config symbols.  Often more
+important, new kernel releases may rename config symbols.  When
+this happens, using a previously working .config file and running
+"make oldconfig" won't necessarily produce a working new kernel
+for you, so you may find that you need to see what NEW kernel
+symbols have been introduced.
+
+To see a list of new config symbols when using "make oldconfig", use
+
+	cp user/some/old.config .config
+	yes "" | make oldconfig >conf.new
+
+and the config program will list as (NEW) any new symbols that have
+unknown values.  Of course, the .config file is also updated with
+new (default) values, so you can use:
+
+	grep "(NEW)" conf.new
+
+to see the new config symbols or you can 'diff' the previous and
+new .config files to see the differences:
+
+	diff .config.old .config | less
+
+(Yes, we need something better here.)
+
+
+======================================================================
+menuconfig
+--------------------------------------------------
+
+SEARCHING for CONFIG symbols
+
+Searching in menuconfig:
+
+	The Search function searches for kernel configuration symbol
+	names, so you have to know something close to what you are
+	looking for.
+
+	Example:
+		/hotplug
+		This lists all config symbols that contain "hotplug",
+		e.g., HOTPLUG, HOTPLUG_CPU, MEMORY_HOTPLUG.
+
+	For search help, enter / followed TAB-TAB-TAB (to highlight
+	<Help>) and Enter.  This will tell you that you can also use
+	regular expressions (regexes) in the search string, so if you
+	are not interested in MEMORY_HOTPLUG, you could try
+
+		/^hotplug
+
+
+______________________________________________________________________
+Color Themes for 'menuconfig'
+
+It is possible to select different color themes using the variable
+MENUCONFIG_COLOR.  To select a theme use:
+
+	make MENUCONFIG_COLOR=<theme> menuconfig
+
+Available themes are:
+  mono       => selects colors suitable for monochrome displays
+  blackbg    => selects a color scheme with black background
+  classic    => theme with blue background. The classic look
+  bluetitle  => a LCD friendly version of classic. (default)
+
+______________________________________________________________________
+Environment variables in 'menuconfig'
+
+KCONFIG_ALLCONFIG
+--------------------------------------------------
+(partially based on lkml email from/by Rob Landley, re: miniconfig)
+--------------------------------------------------
+The allyesconfig/allmodconfig/allnoconfig/randconfig variants can
+also use the environment variable KCONFIG_ALLCONFIG as a flag or a
+filename that contains config symbols that the user requires to be
+set to a specific value.  If KCONFIG_ALLCONFIG is used without a
+filename, "make *config" checks for a file named
+"all{yes/mod/no/random}.config" (corresponding to the *config command
+that was used) for symbol values that are to be forced.  If this file
+is not found, it checks for a file named "all.config" to contain forced
+values.
+
+This enables you to create "miniature" config (miniconfig) or custom
+config files containing just the config symbols that you are interested
+in.  Then the kernel config system generates the full .config file,
+including dependencies of your miniconfig file, based on the miniconfig
+file.
+
+This 'KCONFIG_ALLCONFIG' file is a config file which contains
+(usually a subset of all) preset config symbols.  These variable
+settings are still subject to normal dependency checks.
+
+Examples:
+	KCONFIG_ALLCONFIG=custom-notebook.config make allnoconfig
+or
+	KCONFIG_ALLCONFIG=mini.config make allnoconfig
+or
+	make KCONFIG_ALLCONFIG=mini.config allnoconfig
+
+These examples will disable most options (allnoconfig) but enable or
+disable the options that are explicitly listed in the specified
+mini-config files.
+
+KCONFIG_NOSILENTUPDATE
+--------------------------------------------------
+If this variable has a non-blank value, it prevents silent kernel
+config udpates (requires explicit updates).
+
+KCONFIG_CONFIG
+--------------------------------------------------
+This environment variable can be used to specify a default kernel config
+file name to override the default name of ".config".
+
+KCONFIG_OVERWRITECONFIG
+--------------------------------------------------
+If you set KCONFIG_OVERWRITECONFIG in the environment, Kconfig will not
+break symlinks when .config is a symlink to somewhere else.
+
+KCONFIG_NOTIMESTAMP
+--------------------------------------------------
+If this environment variable exists and is non-null, the timestamp line
+in generated .config files is omitted.
+
+KCONFIG_AUTOCONFIG
+--------------------------------------------------
+This environment variable can be set to specify the path & name of the
+"auto.conf" file.  Its default value is "include/config/auto.conf".
+
+KCONFIG_AUTOHEADER
+--------------------------------------------------
+This environment variable can be set to specify the path & name of the
+"autoconf.h" (header) file.  Its default value is "include/linux/autoconf.h".
+
+______________________________________________________________________
+menuconfig User Interface Options
+----------------------------------------------------------------------
+MENUCONFIG_MODE
+--------------------------------------------------
+This mode shows all sub-menus in one large tree.
+
+Example:
+	MENUCONFIG_MODE=single_menu make menuconfig
+
+======================================================================
+xconfig
+--------------------------------------------------
+
+Searching in xconfig:
+
+	The Search function searches for kernel configuration symbol
+	names, so you have to know something close to what you are
+	looking for.
+
+	Example:
+		Ctrl-F hotplug
+	or
+		Menu: File, Search, hotplug
+
+	lists all config symbol entries that contain "hotplug" in
+	the symbol name.  In this Search dialog, you may change the
+	config setting for any of the entries that are not grayed out.
+	You can also enter a different search string without having
+	to return to the main menu.
+
+
+======================================================================
+gconfig
+--------------------------------------------------
+
+Searching in gconfig:
+
+	None (gconfig isn't maintained as well as xconfig or menuconfig);
+	however, gconfig does have a few more viewing choices than
+	xconfig does.

+   Driver for the Intel Wireless Wimax Connection 2400m
+
+   (C) 2008 Intel Corporation < linux-wimax@intel.com >
+
+   This provides a driver for the Intel Wireless WiMAX Connection 2400m
+   and a basic Linux kernel WiMAX stack.
+
+1. Requirements
+
+     * Linux installation with Linux kernel 2.6.22 or newer (if building
+       from a separate tree)
+     * Intel i2400m Echo Peak or Baxter Peak; this includes the Intel
+       Wireless WiMAX/WiFi Link 5x50 series.
+     * build tools:
+          + Linux kernel development package for the target kernel; to
+            build against your currently running kernel, you need to have
+            the kernel development package corresponding to the running
+            image installed (usually if your kernel is named
+            linux-VERSION, the development package is called
+            linux-dev-VERSION or linux-headers-VERSION).
+          + GNU C Compiler, make
+
+2. Compilation and installation
+
+2.1. Compilation of the drivers included in the kernel
+
+   Configure the kernel; to enable the WiMAX drivers select Drivers >
+   Networking Drivers > WiMAX device support. Enable all of them as
+   modules (easier).
+
+   If USB or SDIO are not enabled in the kernel configuration, the options
+   to build the i2400m USB or SDIO drivers will not show. Enable said
+   subsystems and go back to the WiMAX menu to enable the drivers.
+
+   Compile and install your kernel as usual.
+
+2.2. Compilation of the drivers distributed as an standalone module
+
+   To compile
+
+$ cd source/directory
+$ make
+
+   Once built you can load and unload using the provided load.sh script;
+   load.sh will load the modules, load.sh u will unload them.
+
+   To install in the default kernel directories (and enable auto loading
+   when the device is plugged):
+
+$ make install
+$ depmod -a
+
+   If your kernel development files are located in a non standard
+   directory or if you want to build for a kernel that is not the
+   currently running one, set KDIR to the right location:
+
+$ make KDIR=/path/to/kernel/dev/tree
+
+   For more information, please contact linux-wimax@intel.com.
+
+3. Installing the firmware
+
+   The firmware can be obtained from http://linuxwimax.org or might have
+   been supplied with your hardware.
+
+   It has to be installed in the target system:
+     *
+$ cp FIRMWAREFILE.sbcf /lib/firmware/i2400m-fw-BUSTYPE-1.3.sbcf
+
+     * NOTE: if your firmware came in an .rpm or .deb file, just install
+       it as normal, with the rpm (rpm -i FIRMWARE.rpm) or dpkg
+       (dpkg -i FIRMWARE.deb) commands. No further action is needed.
+     * BUSTYPE will be usb or sdio, depending on the hardware you have.
+       Each hardware type comes with its own firmware and will not work
+       with other types.
+
+4. Design
+
+   This package contains two major parts: a WiMAX kernel stack and a
+   driver for the Intel i2400m.
+
+   The WiMAX stack is designed to provide for common WiMAX control
+   services to current and future WiMAX devices from any vendor; please
+   see README.wimax for details.
+
+   The i2400m kernel driver is broken up in two main parts: the bus
+   generic driver and the bus-specific drivers. The bus generic driver
+   forms the drivercore and contain no knowledge of the actual method we
+   use to connect to the device. The bus specific drivers are just the
+   glue to connect the bus-generic driver and the device. Currently only
+   USB and SDIO are supported. See drivers/net/wimax/i2400m/i2400m.h for
+   more information.
+
+   The bus generic driver is logically broken up in two parts: OS-glue and
+   hardware-glue. The OS-glue interfaces with Linux. The hardware-glue
+   interfaces with the device on using an interface provided by the
+   bus-specific driver. The reason for this breakup is to be able to
+   easily reuse the hardware-glue to write drivers for other OSes; note
+   the hardware glue part is written as a native Linux driver; no
+   abstraction layers are used, so to port to another OS, the Linux kernel
+   API calls should be replaced with the target OS's.
+
+5. Usage
+
+   To load the driver, follow the instructions in the install section;
+   once the driver is loaded, plug in the device (unless it is permanently
+   plugged in). The driver will enumerate the device, upload the firmware
+   and output messages in the kernel log (dmesg, /var/log/messages or
+   /var/log/kern.log) such as:
+
+...
+i2400m_usb 5-4:1.0: firmware interface version 8.0.0
+i2400m_usb 5-4:1.0: WiMAX interface wmx0 (00:1d:e1:01:94:2c) ready
+
+   At this point the device is ready to work.
+
+   Current versions require the Intel WiMAX Network Service in userspace
+   to make things work. See the network service's README for instructions
+   on how to scan, connect and disconnect.
+
+5.1. Module parameters
+
+   Module parameters can be set at kernel or module load time or by
+   echoing values:
+
+$ echo VALUE > /sys/module/MODULENAME/parameters/PARAMETERNAME
+
+   To make changes permanent, for example, for the i2400m module, you can
+   also create a file named /etc/modprobe.d/i2400m containing:
+
+options i2400m idle_mode_disabled=1
+
+   To find which parameters are supported by a module, run:
+
+$ modinfo path/to/module.ko
+
+   During kernel bootup (if the driver is linked in the kernel), specify
+   the following to the kernel command line:
+
+i2400m.PARAMETER=VALUE
+
+5.1.1. i2400m: idle_mode_disabled
+
+   The i2400m module supports a parameter to disable idle mode. This
+   parameter, once set, will take effect only when the device is
+   reinitialized by the driver (eg: following a reset or a reconnect).
+
+5.2. Debug operations: debugfs entries
+
+   The driver will register debugfs entries that allow the user to tweak
+   debug settings. There are three main container directories where
+   entries are placed, which correspond to the three blocks a i2400m WiMAX
+   driver has:
+     * /sys/kernel/debug/wimax:DEVNAME/ for the generic WiMAX stack
+       controls
+     * /sys/kernel/debug/wimax:DEVNAME/i2400m for the i2400m generic
+       driver controls
+     * /sys/kernel/debug/wimax:DEVNAME/i2400m-usb (or -sdio) for the
+       bus-specific i2400m-usb or i2400m-sdio controls).
+
+   Of course, if debugfs is mounted in a directory other than
+   /sys/kernel/debug, those paths will change.
+
+5.2.1. Increasing debug output
+
+   The files named *dl_* indicate knobs for controlling the debug output
+   of different submodules:
+     *
+# find /sys/kernel/debug/wimax\:wmx0 -name \*dl_\*
+/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_tx
+/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_rx

+   engine, just write:
+
+$ echo 3 > /sys/kernel/debug/wimax:wmx0/i2400m/dl_tx
+
+   Increasing numbers yield increasing debug information; for details of
+   what is printed and the available levels, check the source. The code
+   uses 0 for disabled and increasing values until 8.
+
+5.2.2. RX and TX statistics
+
+   The i2400m/rx_stats and i2400m/tx_stats provide statistics about the
+   data reception/delivery from the device:
+
+$ cat /sys/kernel/debug/wimax:wmx0/i2400m/rx_stats
+45 1 3 34 3104 48 480
+
+   The numbers reported are
+     * packets/RX-buffer: total, min, max
+     * RX-buffers: total RX buffers received, accumulated RX buffer size
+       in bytes, min size received, max size received
+
+   Thus, to find the average buffer size received, divide accumulated
+   RX-buffer / total RX-buffers.
+
+   To clear the statistics back to 0, write anything to the rx_stats file:
+
+$ echo 1 > /sys/kernel/debug/wimax:wmx0/i2400m_rx_stats
+
+   Likewise for TX.
+
+   Note the packets this debug file refers to are not network packet, but
+   packets in the sense of the device-specific protocol for communication
+   to the host. See drivers/net/wimax/i2400m/tx.c.
+
+5.2.3. Tracing messages received from user space
+
+   To echo messages received from user space into the trace pipe that the
+   i2400m driver creates, set the debug file i2400m/trace_msg_from_user to
+   1:
+     *
+$ echo 1 > /sys/kernel/debug/wimax:wmx0/i2400m/trace_msg_from_user
+
+5.2.4. Performing a device reset
+
+   By writing a 0, a 1 or a 2 to the file
+   /sys/kernel/debug/wimax:wmx0/reset, the driver performs a warm (without
+   disconnecting from the bus), cold (disconnecting from the bus) or bus
+   (bus specific) reset on the device.
+
+5.2.5. Asking the device to enter power saving mode
+
+   By writing any value to the /sys/kernel/debug/wimax:wmx0 file, the
+   device will attempt to enter power saving mode.
+
+6. Troubleshooting
+
+6.1. Driver complains about 'i2400m-fw-usb-1.2.sbcf: request failed'
+
+   If upon connecting the device, the following is output in the kernel
+   log:
+
+i2400m_usb 5-4:1.0: fw i2400m-fw-usb-1.3.sbcf: request failed: -2
+
+   This means that the driver cannot locate the firmware file named
+   /lib/firmware/i2400m-fw-usb-1.2.sbcf. Check that the file is present in
+   the right location.

+
+   Linux kernel WiMAX stack
+
+   (C) 2008 Intel Corporation < linux-wimax@intel.com >
+
+   This provides a basic Linux kernel WiMAX stack to provide a common
+   control API for WiMAX devices, usable from kernel and user space.
+
+1. Design
+
+   The WiMAX stack is designed to provide for common WiMAX control
+   services to current and future WiMAX devices from any vendor.
+
+   Because currently there is only one and we don't know what would be the
+   common services, the APIs it currently provides are very minimal.
+   However, it is done in such a way that it is easily extensible to
+   accommodate future requirements.
+
+   The stack works by embedding a struct wimax_dev in your device's
+   control structures. This provides a set of callbacks that the WiMAX
+   stack will call in order to implement control operations requested by
+   the user. As well, the stack provides API functions that the driver
+   calls to notify about changes of state in the device.
+
+   The stack exports the API calls needed to control the device to user
+   space using generic netlink as a marshalling mechanism. You can access
+   them using your own code or use the wrappers provided for your
+   convenience in libwimax (in the wimax-tools package).
+
+   For detailed information on the stack, please see
+   include/linux/wimax.h.
+
+2. Usage
+
+   For usage in a driver (registration, API, etc) please refer to the
+   instructions in the header file include/linux/wimax.h.
+
+   When a device is registered with the WiMAX stack, a set of debugfs
+   files will appear in /sys/kernel/debug/wimax:wmxX can tweak for
+   control.
+
+2.1. Obtaining debug information: debugfs entries
+
+   The WiMAX stack is compiled, by default, with debug messages that can
+   be used to diagnose issues. By default, said messages are disabled.
+
+   The drivers will register debugfs entries that allow the user to tweak
+   debug settings.
+
+   Each driver, when registering with the stack, will cause a debugfs
+   directory named wimax:DEVICENAME to be created; optionally, it might
+   create more subentries below it.
+
+2.1.1. Increasing debug output
+
+   The files named *dl_* indicate knobs for controlling the debug output
+   of different submodules of the WiMAX stack:
+     *
+# find /sys/kernel/debug/wimax\:wmx0 -name \*dl_\*
+/sys/kernel/debug/wimax:wmx0/wimax_dl_stack
+/sys/kernel/debug/wimax:wmx0/wimax_dl_op_rfkill
+/sys/kernel/debug/wimax:wmx0/wimax_dl_op_reset
+/sys/kernel/debug/wimax:wmx0/wimax_dl_op_msg
+/sys/kernel/debug/wimax:wmx0/wimax_dl_id_table
+/sys/kernel/debug/wimax:wmx0/wimax_dl_debugfs
+/sys/kernel/debug/wimax:wmx0/.... # other driver specific files
+
+       NOTE: Of course, if debugfs is mounted in a directory other than
+       /sys/kernel/debug, those paths will change.
+
+   By reading the file you can obtain the current value of said debug
+   level; by writing to it, you can set it.
+
+   To increase the debug level of, for example, the id-table submodule,
+   just write:
+
+$ echo 3 > /sys/kernel/debug/wimax:wmx0/wimax_dl_id_table
+
+   Increasing numbers yield increasing debug information; for details of
+   what is printed and the available levels, check the source. The code
+   uses 0 for disabled and increasing values until 8.
