From: José Roberto de Souza <[email protected]> Implements changes around PSR for alderlake-P:
- EDP_SU_TRACK_ENABLE was removed and bit 30 now has other function - Some bits of PSR2_MAN_TRK_CTL moved and SF_PARTIAL_FRAME_UPDATE was removed setting SU_REGION_START/END_ADDR will do this job - SU_REGION_START/END_ADDR have now line granularity but will need to be aligned with DSC when the PSRS + DSC support lands BSpec: 50422 BSpec: 50424 Cc: Gwan-gyeong Mun <[email protected]> Cc: Anusha Srivatsa <[email protected]> Signed-off-by: José Roberto de Souza <[email protected]> Signed-off-by: Clinton Taylor <[email protected]> Signed-off-by: Matt Roper <[email protected]> --- drivers/gpu/drm/i915/display/intel_psr.c | 51 +++++++++++++++++++----- drivers/gpu/drm/i915/i915_reg.h | 26 +++++++----- 2 files changed, 56 insertions(+), 21 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_psr.c b/drivers/gpu/drm/i915/display/intel_psr.c index e71d2dd6a4a5..752de6f8df61 100644 --- a/drivers/gpu/drm/i915/display/intel_psr.c +++ b/drivers/gpu/drm/i915/display/intel_psr.c @@ -519,11 +519,13 @@ static u32 intel_psr2_get_tp_time(struct intel_dp *intel_dp) static void hsw_activate_psr2(struct intel_dp *intel_dp) { struct drm_i915_private *dev_priv = dp_to_i915(intel_dp);
