Subject: [PATCH] drm/amd/display: fix cursor offset on rotation 180
Date: Tue, 31 Jan 2023 15:05:46 -0100	[thread overview]
Message-ID: <20230131160546.150611-1-mwen@igalia.com> (raw)

Cursor gets clipped off in the middle of the screen with hw rotation
180. Fix a miscalculation of cursor offset when it's placed near the
edges in the pipe split case.

Cursor bugs with hw rotation were reported on AMD issue tracker:
https://gitlab.freedesktop.org/drm/amd/-/issues/2247

The issues on rotation 270 was fixed by:
https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/
that partially addressed the rotation 180 too. So, this patch is the
final bits for rotation 180.
