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 Also had to refactor intel_can_enable_sagv function, as current seems to be outdated and using skl specific workarounds, also not following BSpec for Gen11+. v25: Rebased patch series as part was merged already v26: Had to resend the whole series as one more mid patch was added v27: Patches 2,3,7 were pushed, have to resend the series to prevent build failure. v28: PCode patch was merged, one patch was added, sent new series. v30: 3 patches merged, resending the rest with comments fixed Stanislav Lisovskiy (3): drm/i915: Add TGL+ SAGV support 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 | 137 ++++++++++---- drivers/gpu/drm/i915/display/intel_bw.h | 9 + drivers/gpu/drm/i915/display/intel_display.c | 8 +- .../drm/i915/display/intel_display_types.h | 5 + drivers/gpu/drm/i915/intel_pm.c | 168 +++++++++++++++--- drivers/gpu/drm/i915/intel_pm.h | 2 + 6 files changed, 268 insertions(+), 61 deletions(-)
