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 Also had to refactor intel_can_enable_sagv function, as current seems to be outdated and using skl specific workarounds, also not following BSpec for Gen11+.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 drivers/gpu/drm/i915/display/intel_bw.c | 187 ++++++-- drivers/gpu/drm/i915/display/intel_bw.h | 24 + drivers/gpu/drm/i915/display/intel_display.c | 21 +- .../drm/i915/display/intel_display_types.h | 6 + drivers/gpu/drm/i915/i915_reg.h | 5 + drivers/gpu/drm/i915/intel_pm.c | 421 ++++++++++++++++-- drivers/gpu/drm/i915/intel_pm.h | 8 +- drivers/gpu/drm/i915/intel_sideband.c | 2 + 8 files changed, 565 insertions(+), 109 deletions(-)
