[PATCH 1/2] drm/i915: Move the PIPEMISC write the correct place

[PATCH 1/2] drm/i915: Move the PIPEMISC write the correct place

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

I fumbled the PIPEMISC write into the wrong place. It only gets
called for fastsets, but since value needs to be updated based on
the set of active planes it needs to be done for all plane updates.
Move it to the correct spot.

The symptoms include SDR planes never showing up if a previous
modeset/fastset left the pipe in HDR mode. This was immediately
obvious when running the kms_plane pixel format tests. Unfortunately
the test didn't realize it was scanning out pure black all the time
and declared success anyway.

[PATCH 2/2] drm/i915: Allow ICL pipe "HDR mode" when the cursor is visible

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Turns out the cursor is compatible with the pipe "HDR mode". It's
only the actual SDR planes that get entirely bypassed during
blending. So let's ignore the cursor when checking if we have
any planes active that aren't HDR compatible. This fixes the
regressions in the kms_cursor_crc and kms_plane_cursor tests.

Checked for details around this in spec, couldn't get anything specific around how cursor
behaves wrt HDR_MODE. But with the test results it appears that they do follow the HDR
precision. With this observation and data, change looks ok.

Yeah, the spec is rather vague on this topic.
