[v17,0/7] Refactor Gen11+ SAGV support

Message

Lisovskiy, Stanislav Feb. 20, 2020, 12:07 p.m. UTC

For Gen11+ platforms BSpec suggests disabling specific
QGV points separately, depending on bandwidth limitations
and current display configuration. Thus it required adding
a new PCode request for disabling QGV points and some
refactoring of already existing SAGV code.
Also had to refactor intel_can_enable_sagv function,
as current seems to be outdated and using skl specific
workarounds, also not following BSpec for Gen11+.

v17: Had to rebase the whole series.

Stanislav Lisovskiy (7):
  drm/i915: Start passing latency as parameter
  drm/i915: Introduce skl_plane_wm_level accessor.
  drm/i915: Init obj state in intel_atomic_get_old/new_global_obj_state
  drm/i915: Refactor intel_can_enable_sagv
  drm/i915: Added required new PCode commands
  drm/i915: Restrict qgv points which don't have enough bandwidth.
  drm/i915: Enable SAGV support for Gen12
