drm/amd/display: Use kvzalloc for potentially large allocations

2018-05-09T20:16:13+00:00

Allocating up to 32 physically contiguous pages can easily fail (and has
failed for me), and isn't necessary anyway.

Adding missing call to cache current backlight values.
Otherwise the brightness resets to default value on resume.

Some functions definitions have either the initial open brace and/or
the closing brace outside of column 1.

Move those braces to column 1.

This allows various function analyzers like gnu complexity to work
properly for these modified functions.

drm/amd/display: Fixed dim around 1sec when resume from S3 (v2)

2018-03-14T21:01:14+00:00

root cause:
DMCU try to perform a smoothness brightness change.Incorrect initial
brightness level causes the 1 sec dim.
Change:
Cache brightness level in stream, and clear it when edp backlight on.
If brightness level in stream is 0, set brightness with ramp value is 0.
DMCU will set the brightness without smoothness transition.

drm/amd/display: use HW hdr mult for brightness boost

2018-03-14T20:08:46+00:00

In MPO scenario when playing SDR clip in HDR desktop mode, Win is
boosting desktop and requests driver to boost MPO. But driver boosting
is currently done in regamma which is stream property and thus shared
between grph and video.

Redesigning the boosting in RV: use CM_HDR_MULT register which was added
for this scenario. It also has the benefit that it can be done in HIRQL.
