[Intel-gfx] [v6 0/2] Re-enable FBC on TGL

[Uma Shankar]

FBC was disabled on TGL due to random underruns. It has
been determined that FBC will not work reliably with PSR2.
This series re-enables fbc along with taking care of the
PSR2 limitations for TGL.

Bspec: 50422 HSD: 14010260002

v2: Addressed review comments and added bspec links

v3: Addressed Ville's review comments

v4: Change the WA as per Jose's recommendation.

v5: Addressed Jose's review comments.

v6: Added Jose and Ville RB's. Fixed a minor review
comment.

[Intel-gfx] [v6 1/2] drm/i915/display/tgl: Disable FBC with PSR2

[Uma Shankar]

There are some corner cases wrt underrun when we enable
FBC with PSR2 on TGL. Recommendation from hardware is to
keep this combination disabled.

Bspec: 50422 HSD: 14010260002

v2: Added psr2 enabled check from crtc_state (Anshuman)
Added Bspec link and HSD referneces (Jose)

v3: Moved the logic to disable fbc to intel_fbc_update_state_cache
and removed the crtc->config usages, as per Ville's recommendation.

v4: Introduced a variable in fbc state_cache instead of the earlier
plane.visible WA, as suggested by Jose.

v5: Dropped an extra check for fbc in intel_fbc_enable and addressed
review comments by Jose.

v6: Move WA to end of function and added Jose's RB.

[Intel-gfx] [v6 2/2] Revert "drm/i915/display/fbc: Disable fbc by default on TGL"

[Uma Shankar]

FBC can be re-enabled on TGL with WA of keeping it disabled
while PSR2 is enabled.

This reverts commit 2982ded2ff5ce0cf1a49bc39a526da182782b664.
