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. diff --git a/Documentation/input/event-codes.txt b/Documentation/input/event-codes.txt new file mode 100644 index 0000000..23fcb05 --- /dev/null +++ b/Documentation/input/event-codes.txt @@ -0,0 +1,262 @@ +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. diff --git a/Documentation/md.txt b/Documentation/md.txt index a81c7b4..2366b1c 100644 --- a/Documentation/md.txt +++ b/Documentation/md.txt @@ -552,6 +552,16 @@ also have within the array where IO will be blocked.
