This patch makes it possible for user to limit used PSR mode and prevent SU Region Early Transport by setting enable_psr as 2. With default (-1) PSR2 SU Region Early Transport is allowed. v2: fix/improve commit desciption Signed-off-by: Jouni Högander Reviewed-by: Animesh Manna --- drivers/gpu/drm/i915/display/intel_psr.c | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/display/intel_psr.c b/drivers/gpu/drm/i915/display/intel_psr.c index cfce0fe05d92..800cfeabc139 100644 --- a/drivers/gpu/drm/i915/display/intel_psr.c +++ b/drivers/gpu/drm/i915/display/intel_psr.c @@ -235,6 +235,16 @@ static bool psr2_global_enabled(struct intel_dp *intel_dp) } } +static bool psr2_su_region_et_global_enabled(struct intel_dp *intel_dp) +{ + struct drm_i915_private *i915 = dp_to_i915(intel_dp); + + if (i915->display.params.enable_psr != -1) + return false; + + return true; +} + static bool panel_replay_global_enabled(struct intel_dp *intel_dp) { struct drm_i915_private *i915 = dp_to_i915(intel_dp); @@ -683,7 +693,8 @@ static bool psr2_su_region_et_valid(struct intel_dp *intel_dp, bool panel_replay return panel_replay ? intel_dp->pr_dpcd & DP_PANEL_REPLAY_EARLY_TRANSPORT_SUPPORT : - intel_dp->psr_dpcd[0] == DP_PSR2_WITH_Y_COORD_ET_SUPPORTED; + intel_dp->psr_dpcd[0] == DP_PSR2_WITH_Y_COORD_ET_SUPPORTED && + psr2_su_region_et_global_enabled(intel_dp); } static void _panel_replay_enable_sink(struct intel_dp *intel_dp,
