[Intel-gfx] [PATCH] drm/i915/quirks: Add inverted backlight quirk for HP 14-r206nv

[Intel-gfx] [PATCH] drm/i915/quirks: Add inverted backlight quirk for HP 14-r206nv

[Mavroudis Chatzilaridis]

This laptop uses inverted backlight PWM. Thus, without this quirk,
backlight brightness decreases as the brightness value increases and
vice versa.

Thanks for the patch, but this really needs a bug filed at fdo gitlab
with dmesg, VBT, etc. [1]

I don't doubt you, but the fix may need to be different. All the
previous quirks were on ancient GM45, and I was pretty sure the problems
were limited to that platform. I'm hesitant to add the quirk to other
platforms without more info.

Thanks,
Jani.

So we pretty much exhausted all the possibilities at [2], and we're left
with the quirk. I've pushed this to drm-intel-next with cc: stable,
thanks for the patch.

BR,
Jani.


PS. For posterity, this did pass BAT and IGT despite the CI reply in
this thread [3].
