Package: src:linux
Version: 4.11.6-1~bpo9+1
Severity: wishlist
Dear Maintainer,
With kernel 4.11, a feature has been added which allows the LED drivers to
indicate why a change in value has occurred. Including allowing the userland
to know if it was a software or a hardware event which made the brightness
change. This would be super-useful to have, especially when trying to write
tooling to manage keyboard backlights on modern thinkpads.
I believe the tpacpi driver has been updated to support this feature, so all
which would be required from the kernel maintainers would be to enable the
feature CONFIG_LEDS_BRIGHTNESS_HW_CHANGED and then, ideally, upload a new
backport :-)
Thanks,
Daniel.
(I'll leave this stuff in, even though it's not really necessary, it might be
of interest to someone looking at modern thinkpad support ;-)
