Subject: [PATCH v3 00/17] *** Implement simple haptic HID support ***
Date: Fri, 13 May 2022 09:39:10 +0000 [thread overview]
Message-ID: <20220513093927.1632262-1-acz@semihalf.com> (raw)
This patch series introduces changes necessary to support devices
using simple haptic HID pages.
Implementation attempts to follow the discussion below:
https://www.spinics.net/lists/linux-input/msg61091.html
Introduce new haptic defines as specified in HID Usage Tables.
Add new force feedback effect type in order to facilitate using
simple haptic force feedback.
Add INPUT_PROP_HAPTIC_TOUCHPAD to mark touchpad exposing simple haptic
support.
Add new struct hid_haptic_device so as to gather simple haptic related
configuration and current state of the device.
Add new functions to be triggered during HID input mapping and
configuration in order to detect simple haptic devices.
Modify HID input so that haptic output reports are parsed.
Initialize a haptic device.
Modify FF core so that effect IDs can be shared between multiple open file
handles.
Add shared release and press effects for a simple haptic device.
Calculate pressure resolution if units are grams or newtons.
Add support for kernel-driven mode of simple haptic device.
Toggle ABS_PRESSURE generation by input-mt on request.
Implement functions allowing switching between kernel-managed mode
and autonomous mode.
Add simple haptic support for hid-multitouch driver.
Implement EVIOCFF(TAKE|RELEASE)CONTROL ioctls so that userspace can take
and release control of shared release and press effects.
Fix i2c hid sending and getting report so that report IDs larger than 0xF
are handled correctly.
v2:
- Describe INPUT_PROP_HAPTIC_TOUCHPAD in
Documentation/input/event-codes.rst
- Do not extract mt_get_feature(), use hid_hw_wait() instead
- Define HID_UNIT_GRAM and HID_UNIT_NEWTON
- Calculate pressure sum in input-mt if INPUT_MT_TOTAL_FORCE flags set
- Use u* instead of __u* in struct hid_haptic_device
- Solve problems with report IDS >= 0xF as Dmitry suggests
v3:
- Get rid of INPUT_PROP_HAPTIC_TOUCHPAD property as haptic device does not
gave to be a touchpad
- Introduce notion of haptic forcepads; generate haptic feedback in kernel
mode only for forcepads
- Generate clicks based on maximum pressure across slots instead of the sum
- Fix off-by-one bug in hid_haptic_upload_effect()
- Fix resume/suspend: issue hid_haptic_resume() in mt_resume() and
hid_haptic_suspend() in mt_suspend()
- Add reset callback for HID i2c devices
- Implement reset callback for HID multitouch haptic devices
- Implement lid handler triggering touchpad recalibration for Redrix
