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as current seems to be outdated and using skl specific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+.
Stanislav Lisovskiy (11):
drm/i915: Introduce skl_plane_wm_level accessor.
drm/i915: Add intel_atomic_get_bw_*_state helpers
drm/i915: Prepare to extract gen specific functions from
intel_can_enable_sagv
drm/i915: Add pre/post plane updates for SAGV
drm/i915: Use bw state for per crtc SAGV evaluation
drm/i915: Separate icl and skl SAGV checking
drm/i915: Add TGL+ SAGV support
drm/i915: Added required new PCode commands
drm/i915: Rename bw_state to new_bw_state
drm/i915: Restrict qgv points which don't have enough bandwidth.
drm/i915: Enable SAGV support for Gen12
