[Intel-gfx] [PATCH] drm/i915/display/fbc: Implement WA 22010751166

[Intel-gfx] [PATCH] drm/i915/display/fbc: Implement WA 22010751166

[José Roberto de Souza]

Underruns happens when plane height + y offset is not a module of 4
when FBC is enabled.

Specification says that it only affects TGL display C stepping and
newer but to simply the check and as TGL is already in final costumers
hands, pre-production display stepping A and B was also included.

BSpec: 52888 EHL/JSL
BSpec: 52890/55378 TGL

I think you meant 'modulo' rather than 'module' here.

> when FBC is enabled.

Technically the workaround calls for us to just do our FBC disables for
non-modulo 4 planes when the scanline is at vactive-10, but that doesn't
seem to be something that's actually feasible to do at the software
level.  Just keeping FBC disabled when working with planes of the
problematic size as you do here does seem like the safest approach.
Should we make a note of our slight deviation from the workaround
details here?
