Hogander, Jouni Jan. 27, 2023, 8:27 a.m. UTC
SEL_FETCH_CTL registers are armed immediately when plane is disabled.
SEL_FETCH_* instances of plane configuration are used when doing
selective update and normal plane register instances for full updates.
Currently all SEL_FETCH_* registers are written as a part of noarm
plane configuration. If noarm and arm plane configuration are not
happening within same vblank we may end up having plane as a part of
selective update before it's PLANE_SURF register is written.

Fix this by splitting plane selective fetch configuration into arm and
noarm versions and call them accordingly. Write SEL_FETCH_CTL in arm
version.

v2:
 - drop color_plane parameter from arm part
 - dev_priv -> i915 in arm part

Does this helps to revert the set of SFF and CFF at the same time?

Missing rename intel_psr2_disable_plane_sel_fetch() to intel_psr2_disable_plane_sel_fetch_arm().

With this LGTM.
