Subject: [PATCHv2 0/7] Support inhibiting input devices
Date: Fri, 15 May 2020 18:49:43 +0200
Message-ID: <20200515164943.28480-1-andrzej.p@collabora.com> (raw)
In-Reply-To: <20200506002746.GB89269@dtor-ws>

Userspace might want to implement a policy to temporarily disregard input
from certain devices, including not treating them as wakeup sources.

An example use case is a 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 2-5/7). Patches 2-5 are only being sent
to relevant mailing lists and maintainers.

PATCH 6/7 adds support for inhibiting input devices, while PATCH 7/7
provides an example how to convert a driver to take advantage of this
new feature. Patch 7/7 is only being sent to input mailing list and
maintainer.

This work is inspired by:

https://chromium.googlesource.com/chromiumos/third_party/kernel/+/45c2d7bb398f74adfae0017e20b224152fde3822

and

https://chromium.googlesource.com/chromiumos/third_party/kernel/+/4ce0e8a3697edb8fd071110b3af65014512061c7

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 (5):
  Input: add input_device_enabled()
