Input: add ABS_SND_PROFILE

2025-12-19T05:34:42+00:00

ABS_SND_PROFILE used to describe the state of a multi-value sound profile switch. This will be used for the alert-slider on OnePlus phones or other phones. Profile values added as SND_PROFLE_(SILENT|VIBRATE|RING) identifiers to input-event-codes.h so they can be used from DTS.

Input: rename INPUT_PROP_HAPTIC_TOUCHPAD to INPUT_PROP_PRESSUREPAD

2025-11-18T07:18:32+00:00

And expand it to encompass all pressure pads. Definition: "pressure pad" as used here as includes all touchpads that use physical pressure to convert to click, without physical hinges. Also called haptic touchpads in general parlance, Synaptics calls them ForcePads. Most (all?) pressure pads are currently advertised as INPUT_PROP_BUTTONPAD. The suggestion to identify them as pressure pads by defining the resolution on ABS_MT_PRESSURE has been in the docs since commit 20ccc8dd38a3 ("Documentation: input: define ABS_PRESSURE/ABS_MT_PRESSURE resolution as grams") but few devices provide this information. In userspace it's thus impossible to determine whether a device is a true pressure pad (pressure equals pressure) or a normal clickpad with (pressure equals finger size). Commit 7075ae4ac9db ("Input: add INPUT_PROP_HAPTIC_TOUCHPAD") introduces INPUT_PROP_HAPTIC_TOUCHPAD but restricted it to those touchpads that have support for userspace-controlled effects. Let's expand and rename that definition to include all pressure pad touchpads since those that do support FF effects can be identified by the presence of the FF_HAPTIC bit. This means: - clickpad: INPUT_PROP_BUTTONPAD - pressurepad: INPUT_PROP_BUTTONPAD + INPUT_PROP_PRESSUREPAD - pressurepad with configurable haptics: INPUT_PROP_BUTTONPAD + INPUT_PROP_PRESSUREPAD + FF_HAPTIC Signed-off-by: Peter Hutterer Acked-by: Benjamin Tissoires Link: https://patch.msgid.link/20251106114534.GA405512@tassie Signed-off-by: Dmitry Torokhov

Input: Add keycodes for electronic privacy screen on/off hotkeys

2025-10-28T15:11:57+00:00

Add keycodes for hotkeys toggling the electronic privacy screen found on some laptops on/off. There already is an API for eprivacy screens as kernel-mode-setting drm connector object properties: https://www.kernel.org/doc/html/latest/gpu/drm-kms.html#standard-connector-properties this API also supports reporting when the eprivacy screen is turned on/off by the embedded-controller (EC) in response to hotkey presses. But on some laptops (e.g. the Dell Latitude 7300) the firmware does not allow querying the presence nor the status of the eprivacy screen at boot. This makes it impossible to implement the drm connector properties API since drm objects do not allow adding new properties after creation and the presence of the eprivacy cannot be detected at boot. The first notice of the presence of an eprivacy screen on these laptops is an EC generated (WMI) event when the eprivacy screen hotkeys are pressed. In this case the new keycodes this change adds can be generated to notify userspace of the eprivacy screen on/off hotkeys being pressed, so that userspace can show the usual on-screen-display (OSD) notification for eprivacy screen on/off to the user. This is similar to how e.g. touchpad on/off keycodes are used to show the touchpad on/off OSD.

Input: add keycode for performance mode key

2025-08-05T20:51:10+00:00

Alienware calls this key "Performance Boost". Dell calls it "G-Mode". The goal is to have a specific keycode to detect when this key is pressed, so userspace can act upon it and do what have to do, usually starting the power profile for performance.

Input: Add and document BTN_GRIP*

2025-07-27T08:41:20+00:00

Many controllers these days have started including grip buttons. As there has been no particular assigned BTN_* constants for these, they've been haphazardly assigned to BTN_TRIGGER_HAPPY*. Unfortunately, the assignment of these has varied significantly between drivers. Add and document new constants for these grip buttons.

Since USB audio devices can have a slew of different configurations that reach beyond the basic headset and headphone use cases, classify these devices differently.

The F11 key on the new Lenovo Thinkpad T14 Gen 5, T16 Gen 3, and P14s Gen 5 laptops includes a symbol showing a smartphone and a laptop chained together. According to the user manual, it starts the Microsoft Phone Link software used to connect to Android/iOS devices and relay messages/calls or sync data.
