Debugging input devices, specifically laptop touchpads, can be tricky without having the physical device handy. Here we try to remedy that with userio. This module allows an application to connect to a character device provided by the kernel, and emulate any serio device. In combination with userspace programs that can record PS/2 devices and replay them through the /dev/userio device, this allows developers to debug driver issues on the PS/2 level with devices simply by requesting a recording from the user experiencing the issue without having to have the physical hardware in front of them.

Hardware manufacturers group keys in the weirdest way possible. This may cause a power-key to be grouped together with normal keyboard keys and thus be reported on the same kernel interface. However, user-space is often only interested in specific sets of events. For instance, daemons dealing with system-reboot (like systemd-logind) listen for KEY_POWER, but are not interested in any main keyboard keys. Usually, power keys are reported via separate interfaces, however, some i8042 boards report it in the AT matrix. To avoid waking up those system daemons on each key-press, we had two ideas: - split off KEY_POWER into a separate interface unconditionally - allow filtering a specific set of events on evdev FDs Splitting of KEY_POWER is a rather weird way to deal with this and may break backwards-compatibility. It is also specific to KEY_POWER and might be required for other stuff, too. Moreover, we might end up with a huge set of input-devices just to have them properly split. Hence, this patchset implements the second idea: An event-mask to specify which events you're interested in. Two ioctls allow setting this mask for each event-type. If not set, all events are reported. The type==0 entry is used same as in EVIOCGBIT to set the actual EV_* mask of filtered events. This way, you have a two-level filter. We are heavily forward-compatible to new event-types and event-codes. So new user-space will be able to run on an old kernel which doesn't know the given event-codes or event-types.

由 Franklin S Cooper Jr 提交于
In the touchscreen controller ISR, reading the tsc starting from register 0x2 causes the tsc to infrequently update the detected finger's x and y coordinate. The irq pin toggles at a fast rate to indicate touch events are happening. However, the tsc on average updates the touch point's x and y value every ~100 ms which is much slower than the advertised rate of 100+ Hz. This leads to multiple reads within this ~100 ms time window returning the same value. Example: X: 10 , Y: 30 X: 10 , Y: 30 X: 10, Y: 30 .. // After 100 ms X: 300, Y: 300 X: 300, y: 300 .. // After 100 ms X: 1743, Y: 621 X: 1743, Y: 621 For some reason if instead of starting to read at register 0x2 you start reading at register 0x0 this issue isn't seen. This seems like a quirk only seen in the EDT FT5506 so to fix this issue simply adjust the code to start reading from 0x0. Technically this isn't wrong so no regressions should be seen with other touchscreen controllers supported by this driver.

Some encoders have both outputs low in stable states, others also have a stable state with both outputs high (half-period mode) and some have a stable state in all steps (quarter-period mode). The driver used to support the former states and with this change it can also support the later. This commit also deprecates the 'half-period' property and introduces a new property 'steps-per-period'. This property specifies the number of steps (stable states) produced by the rotary encoder for each GPIO period.

There is an undocumented upper bound for the total number of ff effects: FF_GAIN (= 96). This can be found as follows: - user: write(EV_FF, effect_id, iterations) calls kernel: ff->playback(effect_id, ...): starts effect "effect_id" - user: write(EV_FF, FF_GAIN, gain) calls kernel: ff->set_gain(gain, ...): sets gain A collision occurs when effect_id equals FF_GAIN. According to input_ff_event(), FF_GAIN is the smallest value where a collision occurs. Therefore the greatest safe value for effect_id is FF_GAIN - 1, and thus the total number of effects should never exceed FF_GAIN. Define FF_MAX_EFFECTS as FF_GAIN and check on this limit in ff-core.

This changAdd support for EV_ABS / EV_REL events to the gpio-keys-polled driver. The driver already allows specifying what type of events (key / rel / abs) a button generates when pressed, but for rel / abs axis we also need to specify which value this specific gpio represents. One use case is digital joysticks / direction-pads which are hooked up to gpio, in this case we've left and right buttons which we want to map to EV_ABS, ABS_X and we want generate events for left with a value of -1 and for right with a value of +1 (and similar for up / down and ABS_Y).

The pad_nr corresponds to the lit up LED on the controller. Therefore there should be no gaps when enumerating. Currently a LED is only re-assigned after a controller is re-connected 4 times. This patch uses ida to track connected pads - this way we can re-assign freed up pad number immediately. Consider the following case: 1. pad A is connected and gets pad_nr = 0 2. pad B is connected and gets pad_nr = 1 3. pad A is disconnected 4. pad A is connected again using ida_simple_get() controller A now correctly gets pad_nr = 0 again.
