-When: March 2010
-Why: These two features use non-standard interfaces. There are the
- only features that really need multiple path to guess what's
- the right method name on a specific laptop.
-
- Removing them will allow to remove a lot of code an significantly
- clean the drivers.
-
- This will affect the backlight code which won't be able to know
- if the backlight is on or off. The platform display file will also be
- write only (like the one in eeepc-laptop).
-
- This should'nt affect a lot of user because they usually know
- when their display is on or off.

+ How to Get Your Patch Accepted Into the Hwmon Subsystem
+ -------------------------------------------------------
+
+This text is is a collection of suggestions for people writing patches or
+drivers for the hwmon subsystem. Following these suggestions will greatly
+increase the chances of your change being accepted.
+
+
+1. General
+----------
+
+* It should be unnecessary to mention, but please read and follow
+ Documentation/SubmitChecklist
+ Documentation/SubmittingDrivers
+ Documentation/SubmittingPatches
+ Documentation/CodingStyle
+
+* If your patch generates checkpatch warnings, please refrain from explanations
+ such as "I don't like that coding style". Keep in mind that each unnecessary
+ warning helps hiding a real problem. If you don't like the kernel coding
+ style, don't write kernel drivers.
+
+* Please test your patch thoroughly. We are not your test group.
+ Sometimes a patch can not or not completely be tested because of missing
+ hardware. In such cases, you should test-build the code on at least one
+ architecture. If run-time testing was not achieved, it should be written
+ explicitly below the patch header.
+
+* If your patch (or the driver) is affected by configuration options such as
+ CONFIG_SMP or CONFIG_HOTPLUG, make sure it compiles for all configuration
+ variants.
+
+
+2. Adding functionality to existing drivers
+-------------------------------------------
+
+* Make sure the documentation in Documentation/hwmon/<driver_name> is up to
+ date.
+
+* Make sure the information in Kconfig is up to date.
+
+* If the added functionality requires some cleanup or structural changes, split
+ your patch into a cleanup part and the actual addition. This makes it easier
+ to review your changes, and to bisect any resulting problems.
+
+* Never mix bug fixes, cleanup, and functional enhancements in a single patch.
+
+
+3. New drivers
+--------------
+
+* Running your patch or driver file(s) through checkpatch does not mean its
+ formatting is clean. If unsure about formatting in your new driver, run it
+ through Lindent. Lindent is not perfect, and you may have to do some minor
+ cleanup, but it is a good start.
+
+* Consider adding yourself to MAINTAINERS.
+
+* Document the driver in Documentation/hwmon/<driver_name>.
+
+* Add the driver to Kconfig and Makefile in alphabetical order.
+
+* Make sure that all dependencies are listed in Kconfig. For new drivers, it
+ is most likely prudent to add a dependency on EXPERIMENTAL.
+
+* Avoid forward declarations if you can. Rearrange the code if necessary.
+
+* Avoid calculations in macros and macro-generated functions. While such macros
+ may save a line or so in the source, it obfuscates the code and makes code
+ review more difficult. It may also result in code which is more complicated
+ than necessary. Use inline functions or just regular functions instead.
+
+* If the driver has a detect function, make sure it is silent. Debug messages
+ and messages printed after a successful detection are acceptable, but it
+ must not print messages such as "Chip XXX not found/supported".
+
+ Keep in mind that the detect function will run for all drivers supporting an
+ address if a chip is detected on that address. Unnecessary messages will just
+ pollute the kernel log and not provide any value.
+
+* Provide a detect function if and only if a chip can be detected reliably.
+
+* Avoid writing to chip registers in the detect function. If you have to write,
+ only do it after you have already gathered enough data to be certain that the
+ detection is going to be successful.
+
+ Keep in mind that the chip might not be what your driver believes it is, and
+ writing to it might cause a bad misconfiguration.
+
+* Make sure there are no race conditions in the probe function. Specifically,
+ completely initialize your chip first, then create sysfs entries and register
+ with the hwmon subsystem.
+
+* Do not provide support for deprecated sysfs attributes.
+
+* Do not create non-standard attributes unless really needed. If you have to use
+ non-standard attributes, or you believe you do, discuss it on the mailing list
+ first. Either case, provide a detailed explanation why you need the
+ non-standard attribute(s).
+ Standard attributes are specified in Documentation/hwmon/sysfs-interface.
+
+* When deciding which sysfs attributes to support, look at the chip's
+ capabilities. While we do not expect your driver to support everything the
+ chip may offer, it should at least support all limits and alarms.
+
+* Last but not least, please check if a driver for your chip already exists
+ before starting to write a new driver. Especially for temperature sensors,
+ new chips are often variants of previously released chips. In some cases,
+ a presumably new chip may simply have been relabeled.

+The input protocol uses a map of types and codes to express input device values
+to userspace. This document describes the types and codes and how and when they
+may be used.
+
+A single hardware event generates multiple input events. Each input event
+contains the new value of a single data item. A special event type, EV_SYN, is
+used to separate input events into packets of input data changes occurring at
+the same moment in time. In the following, the term "event" refers to a single
+input event encompassing a type, code, and value.
+
+The input protocol is a stateful protocol. Events are emitted only when values
+of event codes have changed. However, the state is maintained within the Linux
+input subsystem; drivers do not need to maintain the state and may attempt to
+emit unchanged values without harm. Userspace may obtain the current state of
+event code values using the EVIOCG* ioctls defined in linux/input.h. The event
+reports supported by a device are also provided by sysfs in
+class/input/event*/device/capabilities/, and the properties of a device are
+provided in class/input/event*/device/properties.
+
+Types:
+==========
+Types are groupings of codes under a logical input construct. Each type has a
+set of applicable codes to be used in generating events. See the Codes section
+for details on valid codes for each type.
+
+* EV_SYN:
+ - Used as markers to separate events. Events may be separated in time or in
+ space, such as with the multitouch protocol.
+
+* EV_KEY:
+ - Used to describe state changes of keyboards, buttons, or other key-like
+ devices.
+
+* EV_REL:
+ - Used to describe relative axis value changes, e.g. moving the mouse 5 units
+ to the left.
+
+* EV_ABS:
+ - Used to describe absolute axis value changes, e.g. describing the
+ coordinates of a touch on a touchscreen.
+
+* EV_MSC:
+ - Used to describe miscellaneous input data that do not fit into other types.
+
+* EV_SW:
+ - Used to describe binary state input switches.
+
+* EV_LED:
+ - Used to turn LEDs on devices on and off.
+
+* EV_SND:
+ - Used to output sound to devices.
+
+* EV_REP:
+ - Used for autorepeating devices.
+
+* EV_FF:
+ - Used to send force feedback commands to an input device.
+
+* EV_PWR:
+ - A special type for power button and switch input.
+
+* EV_FF_STATUS:
+ - Used to receive force feedback device status.
+
+Codes:
+==========
+Codes define the precise type of event.
+
+EV_SYN:
+----------
+EV_SYN event values are undefined. Their usage is defined only by when they are
+sent in the evdev event stream.
+
+* SYN_REPORT:
+ - Used to synchronize and separate events into packets of input data changes
+ occurring at the same moment in time. For example, motion of a mouse may set
+ the REL_X and REL_Y values for one motion, then emit a SYN_REPORT. The next
+ motion will emit more REL_X and REL_Y values and send another SYN_REPORT.
+
+* SYN_CONFIG:
+ - TBD
+
+* SYN_MT_REPORT:
+ - Used to synchronize and separate touch events. See the
+ multi-touch-protocol.txt document for more information.
+
+* SYN_DROPPED:
+ - Used to indicate buffer overrun in the evdev client's event queue.
+ Client should ignore all events up to and including next SYN_REPORT
+ event and query the device (using EVIOCG* ioctls) to obtain its
+ current state.
+
+EV_KEY:
+----------
+EV_KEY events take the form KEY_<name> or BTN_<name>. For example, KEY_A is used
+to represent the 'A' key on a keyboard. When a key is depressed, an event with
+the key's code is emitted with value 1. When the key is released, an event is
+emitted with value 0. Some hardware send events when a key is repeated. These
+events have a value of 2. In general, KEY_<name> is used for keyboard keys, and
+BTN_<name> is used for other types of momentary switch events.
+
+A few EV_KEY codes have special meanings:
+
+* BTN_TOOL_<name>:
+ - These codes are used in conjunction with input trackpads, tablets, and
+ touchscreens. These devices may be used with fingers, pens, or other tools.
+ When an event occurs and a tool is used, the corresponding BTN_TOOL_<name>
+ code should be set to a value of 1. When the tool is no longer interacting
+ with the input device, the BTN_TOOL_<name> code should be reset to 0. All
+ trackpads, tablets, and touchscreens should use at least one BTN_TOOL_<name>
+ code when events are generated.
+
+* BTN_TOUCH:
+ BTN_TOUCH is used for touch contact. While an input tool is determined to be
+ within meaningful physical contact, the value of this property must be set
+ to 1. Meaningful physical contact may mean any contact, or it may mean
+ contact conditioned by an implementation defined property. For example, a
+ touchpad may set the value to 1 only when the touch pressure rises above a
+ certain value. BTN_TOUCH may be combined with BTN_TOOL_<name> codes. For
+ example, a pen tablet may set BTN_TOOL_PEN to 1 and BTN_TOUCH to 0 while the
+ pen is hovering over but not touching the tablet surface.
+
+Note: For appropriate function of the legacy mousedev emulation driver,
+BTN_TOUCH must be the first evdev code emitted in a synchronization frame.
+
+Note: Historically a touch device with BTN_TOOL_FINGER and BTN_TOUCH was
+interpreted as a touchpad by userspace, while a similar device without
+BTN_TOOL_FINGER was interpreted as a touchscreen. For backwards compatibility
+with current userspace it is recommended to follow this distinction. In the
+future, this distinction will be deprecated and the device properties ioctl
+EVIOCGPROP, defined in linux/input.h, will be used to convey the device type.
+
+* BTN_TOOL_FINGER, BTN_TOOL_DOUBLETAP, BTN_TOOL_TRIPLETAP, BTN_TOOL_QUADTAP:
+ - These codes denote one, two, three, and four finger interaction on a
+ trackpad or touchscreen. For example, if the user uses two fingers and moves
+ them on the touchpad in an effort to scroll content on screen,
+ BTN_TOOL_DOUBLETAP should be set to value 1 for the duration of the motion.
+ Note that all BTN_TOOL_<name> codes and the BTN_TOUCH code are orthogonal in
+ purpose. A trackpad event generated by finger touches should generate events
+ for one code from each group. At most only one of these BTN_TOOL_<name>
+ codes should have a value of 1 during any synchronization frame.
+
+Note: Historically some drivers emitted multiple of the finger count codes with
+a value of 1 in the same synchronization frame. This usage is deprecated.
+
+Note: In multitouch drivers, the input_mt_report_finger_count() function should
+be used to emit these codes. Please see multi-touch-protocol.txt for details.
+
+EV_REL:
+----------
+EV_REL events describe relative changes in a property. For example, a mouse may
+move to the left by a certain number of units, but its absolute position in
+space is unknown. If the absolute position is known, EV_ABS codes should be used
+instead of EV_REL codes.
+
+A few EV_REL codes have special meanings:
+
+* REL_WHEEL, REL_HWHEEL:
+ - These codes are used for vertical and horizontal scroll wheels,
+ respectively.
+
+EV_ABS:
+----------
+EV_ABS events describe absolute changes in a property. For example, a touchpad
+may emit coordinates for a touch location.
+
+A few EV_ABS codes have special meanings:
+
+* ABS_DISTANCE:
+ - Used to describe the distance of a tool from an interaction surface. This
+ event should only be emitted while the tool is hovering, meaning in close
+ proximity of the device and while the value of the BTN_TOUCH code is 0. If
+ the input device may be used freely in three dimensions, consider ABS_Z
+ instead.
+
+* ABS_MT_<name>:
+ - Used to describe multitouch input events. Please see
+ multi-touch-protocol.txt for details.
+
+EV_SW:
+----------
+EV_SW events describe stateful binary switches. For example, the SW_LID code is
+used to denote when a laptop lid is closed.
+
+Upon binding to a device or resuming from suspend, a driver must report
+the current switch state. This ensures that the device, kernel, and userspace
+state is in sync.
+
+Upon resume, if the switch state is the same as before suspend, then the input
+subsystem will filter out the duplicate switch state reports. The driver does
+not need to keep the state of the switch at any time.
+
+EV_MSC:
+----------
+EV_MSC events are used for input and output events that do not fall under other
+categories.
+
+EV_LED:
+----------
+EV_LED events are used for input and output to set and query the state of
+various LEDs on devices.
+
+EV_REP:
+----------
+EV_REP events are used for specifying autorepeating events.
+
+EV_SND:
+----------
+EV_SND events are used for sending sound commands to simple sound output
+devices.
+
+EV_FF:
+----------
+EV_FF events are used to initialize a force feedback capable device and to cause
+such device to feedback.
+
+EV_PWR:
+----------
+EV_PWR events are a special type of event used specifically for power
+mangement. Its usage is not well defined. To be addressed later.
+
+Guidelines:
+==========
+The guidelines below ensure proper single-touch and multi-finger functionality.
+For multi-touch functionality, see the multi-touch-protocol.txt document for
+more information.
+
+Mice:
+----------
+REL_{X,Y} must be reported when the mouse moves. BTN_LEFT must be used to report
+the primary button press. BTN_{MIDDLE,RIGHT,4,5,etc.} should be used to report
+further buttons of the device. REL_WHEEL and REL_HWHEEL should be used to report
+scroll wheel events where available.
+
+Touchscreens:
+----------
+ABS_{X,Y} must be reported with the location of the touch. BTN_TOUCH must be
+used to report when a touch is active on the screen.
+BTN_{MOUSE,LEFT,MIDDLE,RIGHT} must not be reported as the result of touch
+contact. BTN_TOOL_<name> events should be reported where possible.
+
+Trackpads:
+----------
+Legacy trackpads that only provide relative position information must report
+events like mice described above.
+
+Trackpads that provide absolute touch position must report ABS_{X,Y} for the
+location of the touch. BTN_TOUCH should be used to report when a touch is active
+on the trackpad. Where multi-finger support is available, BTN_TOOL_<name> should
+be used to report the number of touches active on the trackpad.
+
+Tablets:
+----------
+BTN_TOOL_<name> events must be reported when a stylus or other tool is active on
+the tablet. ABS_{X,Y} must be reported with the location of the tool. BTN_TOUCH
+should be used to report when the tool is in contact with the tablet.
+BTN_{STYLUS,STYLUS2} should be used to report buttons on the tool itself. Any
+button may be used for buttons on the tablet except BTN_{MOUSE,LEFT}.
+BTN_{0,1,2,etc} are good generic codes for unlabeled buttons. Do not use
+meaningful buttons, like BTN_FORWARD, unless the button is labeled for that
+purpose on the device.
Also, the connection is a bit more complex. You'll need a bunch of diodes,
and one pullup resistor. First, you connect the Directions and the button

I've seen reports that bttv 0.7.x crashes whereas 0.8.x works rock solid
for some people. Thus probably a small buglet left somewhere in bttv

+There are a lot of different bt848/849/878/879 based boards available.
Making video work often is not a big deal, because this is handled
completely by the bt8xx chip, which is common on all boards. But
sound is handled in slightly different ways on each board.
To handle the grabber boards correctly, there is a array tvcards[] in
-bttv-cards.c, which holds the informations required for each board.
+bttv-cards.c, which holds the information required for each board.
Sound will work only, if the correct entry is used (for video it often
makes no difference). The bttv driver prints a line to the kernel
log, telling which card type is used. Like this one:

1. Introduction
* Unless work items are expected to consume a huge amount of CPU
cycles, using a bound wq is usually beneficial due to the increased
level of locality in wq operations and work item execution.
+
+
+7. Debugging
+
+Because the work functions are executed by generic worker threads
+there are a few tricks needed to shed some light on misbehaving
+workqueue users.
+
+Worker threads show up in the process list as:
+
+root 5671 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/0:1]
+root 5672 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/1:2]
+root 5673 0.0 0.0 0 0 ? S 12:12 0:00 [kworker/0:0]
+root 5674 0.0 0.0 0 0 ? S 12:13 0:00 [kworker/1:0]
+
+If kworkers are going crazy (using too much cpu), there are two types
+of possible problems:
+
+ 1. Something beeing scheduled in rapid succession
+ 2. A single work item that consumes lots of cpu cycles
+
+The first one can be tracked using tracing:
+
+ $ echo workqueue:workqueue_queue_work > /sys/kernel/debug/tracing/set_event
+ $ cat /sys/kernel/debug/tracing/trace_pipe > out.txt
+ (wait a few secs)
+ ^C
+
+If something is busy looping on work queueing, it would be dominating
+the output and the offender can be determined with the work item
+function.
+
+For the second type of problems it should be possible to just check
+the stack trace of the offending worker thread.
+
+ $ cat /proc/THE_OFFENDING_KWORKER/stack
+
+The work item's function should be trivially visible in the stack
+trace.

+ *
+ * x86-64, mm: Put early page table high
+ *
+ * at some point init_memory_mapping is going to reach the pagetable pages
+ * area and map those pages too (mapping them as normal memory that falls
+ * in the range of addresses passed to init_memory_mapping as argument).
+ * Some of those pages are already pagetable pages (they are in the range
+ * pgt_buf_start-pgt_buf_end) therefore they are going to be mapped RO and
+ * everything is fine.
+ * Some of these pages are not pagetable pages yet (they fall in the range
+ * pgt_buf_end-pgt_buf_top; for example the page at pgt_buf_end) so they
+ * are going to be mapped RW. When these pages become pagetable pages and
+ * are hooked into the pagetable, xen will find that the guest has already
+ * a RW mapping of them somewhere and fail the operation.
+ * The reason Xen requires pagetables to be RO is that the hypervisor needs
+ * to verify that the pagetables are valid before using them. The validation
+ * operations are called "pinning".
+ *
+ * In order to fix the issue we mark all the pages in the entire range
+ * pgt_buf_start-pgt_buf_top as RO, however when the pagetable allocation
+ * is completed only the range pgt_buf_start-pgt_buf_end is reserved by
+ * init_memory_mapping. Hence the kernel is going to crash as soon as one
+ * of the pages in the range pgt_buf_end-pgt_buf_top is reused (b/c those
+ * ranges are RO).
+ *
+ * For this reason, 'mark_rw_past_pgt' is introduced which is called _after_
+ * the init_memory_mapping has completed (in a perfect world we would
+ * call this function from init_memory_mapping, but lets ignore that).
+ *
+ * Because we are called _after_ init_memory_mapping the pgt_buf_[start,
+ * end,top] have all changed to new values (b/c init_memory_mapping
+ * is called and setting up another new page-table). Hence, the first time
+ * we enter this function, we save away the pgt_buf_start value and update
+ * the pgt_buf_[end,top].
+ *
+ * When we detect that the "old" pgt_buf_start through pgt_buf_end
+ * PFNs have been reserved (so memblock_x86_reserve_range has been called),
+ * we immediately set out to RW the "old" pgt_buf_end through pgt_buf_top.
+ *
+ * And then we update those "old" pgt_buf_[end|top] with the new ones
+ * so that we can redo this on the next pagetable.

-config MRST_RAR_HANDLER
- tristate "RAR handler driver for Intel Moorestown platform"
- depends on RAR_REGISTER
- ---help---
- This driver provides a memory management interface to
- restricted access regions (RAR) available on the Intel
- Moorestown platform.
-
- Once locked down, restricted access regions are only
- accessible by specific hardware on the platform. The x86
- CPU is typically not one of those platforms. As such this
- driver does not access RAR, and only provides a buffer
- allocation/bookkeeping mechanism.
-
- If unsure, say N.

-RAR Handler (memrar) Driver TODO Items
-======================================
-
-Maintainer: Eugene Epshteyn <eugene.epshteyn@intel.com>
-
-memrar.h
---------
-1. This header exposes the driver's user space and kernel space
- interfaces. It should be moved to <linux/rar/memrar.h>, or
- something along those lines, when this memrar driver is moved out
- of `staging'.
- a. It would be ideal if staging/rar_register/rar_register.h was
- moved to the same directory.
-
-memrar_allocator.[ch]
----------------------
-1. Address potential fragmentation issues with the memrar_allocator.
-
-2. Hide struct memrar_allocator details/fields. They need not be
- exposed to the user.
- a. Forward declare struct memrar_allocator.
- b. Move all three struct definitions to `memrar_allocator.c'
- source file.
- c. Add a memrar_allocator_largest_free_area() function, or
- something like that to get access to the value of the struct
- memrar_allocator "largest_free_area" field. This allows the
- struct memrar_allocator fields to be completely hidden from
- the user. The memrar_handler code really only needs this for
- statistic gathering on-demand.
- d. Do the same for the "capacity" field as the
- "largest_free_area" field.
-
-3. Move memrar_allocator.* to kernel `lib' directory since it is HW
- neutral.
- a. Alternatively, use lib/genalloc.c instead.
- b. A kernel port of Doug Lea's malloc() implementation may also
- be an option.
-
-memrar_handler.c
-----------------
-1. Split user space interface (ioctl code) from core/kernel code,
- e.g.:
- memrar_handler.c -> memrar_core.c, memrar_user.c

-Description: The Intel Moorestown Restricted Access Region (RAR)
- Handler driver exposes an ioctl() based interface that
- allows a user to reserve and release blocks of RAR
- memory.
-
- Note: A sysfs based one was not appropriate for the
- RAR handler's usage model.
-
- =========================================================
- ioctl() Requests
- =========================================================
- RAR_HANDLER_RESERVE
- -------------------
- Description: Reserve RAR block.
- Type: struct RAR_block_info
- Direction: in/out
- Errors: EINVAL (invalid RAR type or size)
- ENOMEM (not enough RAR memory)
-
- RAR_HANDLER_STAT
- ----------------
- Description: Get RAR statistics.
- Type: struct RAR_stat
- Direction: in/out
- Errors: EINVAL (invalid RAR type)
-
- RAR_HANDLER_RELEASE
- -------------------
- Description: Release previously reserved RAR block.
- Type: 32 bit unsigned integer
- (e.g. uint32_t), i.e the RAR "handle".
- Direction: in
- Errors: EINVAL (invalid RAR handle)
-
-
- =========================================================
- ioctl() Request Parameter Types
- =========================================================
- The structures referred to above are defined as
- follows:
-
- /**
- * struct RAR_block_info - user space struct that
- * describes RAR buffer
- * @type: Type of RAR memory (e.g.,
- * RAR_TYPE_VIDEO or RAR_TYPE_AUDIO) [in]
- * @size: Requested size of a block in bytes to
- * be reserved in RAR. [in]
- * @handle: Handle that can be used to refer to
- * reserved block. [out]
- *
- * This is the basic structure exposed to the user
- * space that describes a given RAR buffer. It used
- * as the parameter for the RAR_HANDLER_RESERVE ioctl.
- * The buffer's underlying bus address is not exposed
- * to the user. User space code refers to the buffer
- * entirely by "handle".
- */
- struct RAR_block_info {
- __u32 type;
- __u32 size;
- __u32 handle;
- };
-
- /**
- * struct RAR_stat - RAR statistics structure
- * @type: Type of RAR memory (e.g.,
- * RAR_TYPE_VIDEO or
- * RAR_TYPE_AUDIO) [in]
- * @capacity: Total size of RAR memory
- * region. [out]
- * @largest_block_size: Size of the largest reservable
- * block. [out]
- *
- * This structure is used for RAR_HANDLER_STAT ioctl.
- */
- struct RAR_stat {
- __u32 type;
- __u32 capacity;
- __u32 largest_block_size;
- };
-
- Lastly, the RAR_HANDLER_RELEASE ioctl expects a
- "handle" to the RAR block of memory. It is a 32 bit
- unsigned integer.
