Subject: drm/i915: Split update_plane() into update_noarm() + update_arm()
MIME-Version: 1.0

Git-commit: 8ac80733cf6f08b9fdac9bf6800dd81e9304b4c6
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
The amount of plane registers we have to write has been steadily
increasing, putting more pressure on the vblank evasion mechanism
and forcing us to increase its time budget. Let's try to take some
of the pressure off by splitting plane updates into two parts:
1) write all non-self arming plane registers, ie. the registers
where the write actually does nothing until a separate arming
register is also written which will cause the hardware to latch
the new register values at the next start of vblank
2) write all self arming plane registers, ie. registers which always
just latch at the next start of vblank, and registers which also
arm other registers to do so
Here we just provide the mechanism, but don't actually implement
the split on any platform yet. so everything stays now in the _arm()
hooks. Subsequently we can move a whole bunch of stuff into the
_noarm() part, especially in more modern platforms where the number
of registers we have to write is also the greatest. On older
platforms this is less beneficial probably, but no real reason
to deviate from a common behaviour.
And let's sprinkle some TODOs around the areas that will need
adapting.
