Subject: [PATCH v3 0/7] Support inhibiting input devices
Userspace might want to implement a policy to temporarily disregard input
from certain devices.
An example use case is a convertible laptop, whose keyboard can be folded
under the screen to create tablet-like experience. The user then must hold
the laptop in such a way that it is difficult to avoid pressing the keyboard
keys. It is therefore desirable to temporarily disregard input from the
keyboard, until it is folded back. This obviously is a policy which should
be kept out of the kernel, but the kernel must provide suitable means to
implement such a policy.
Due to interactions with suspend/resume, a helper has been added for drivers
to decide if the device is being used or not (PATCH 1/7) and it has been
applied to relevant drivers (PATCH 2,4,5,6/7).
PATCH 7/7 adds support for inhibiting input devices.
This work is inspired by:
https://chromium.googlesource.com/chromiumos/third_party/kernel/+/45c2d7bb398f74adfae0017e20b224152fde3822
and
https://chromium.googlesource.com/chromiumos/third_party/kernel/+/4ce0e8a3697edb8fd071110b3af65014512061c7
In this respin the elan_i2c patch is dropped and converting it will be
addressed later.
v2..v3:
- ignored autorepeat events in input_get_disposition() if a key is not
pressed (Hans)
- dropped inhibit()/uninhibit() driver callbacks (Hans)
- split ACPI button patch into taking the lock and using the helper (Rafael)
- dropped the elan_i2c conversion
- fixed typos in exynos adc
v1..v2:
- added input_device_enabled() helper and used it in drivers (Dmitry)
- the fact of open() and close() being called in inhibit/uninhibit paths has
been emphasized in the commit message of PATCH 6/7 (Dmitry)
Andrzej Pietrasiewicz (6):
Input: add input_device_enabled()
Input: use input_device_enabled()
ACPI: button: Access input device's users under appropriate mutex
ACPI: button: Use input_device_enabled() helper
iio: adc: exynos: Use input_device_enabled()
platform/x86: thinkpad_acpi: Use input_device_enabled()
Patrik Fimml (1):
Input: Add "inhibited" property
