drm/i915/gen9: Store plane minimum blocks in CRTC wm state (v2)
|
||
|
|
||
|
This will eventually allow us to re-use old values without
|
||
|
re-calculating them for unchanged planes (which also helps us avoid
|
||
|
re-grabbing extra plane states).
|
||
|
|
||
|
v2:
|
||
|
- Drop unnecessary memset's; they were meant for a later patch (which
|
||
|
got reworked anyway to not need them, but were mis-rebased into this
|
||
|
one. (Maarten)
