From: Alvin Lee Date: Tue, 8 Nov 2022 23:46:52 +0000 (-0500) Subject: drm/amd/display: Check if PSR enabled when entering MALL X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bf29274d77888f55cace715ec4e7bcd107aa8316;p=linux.git drm/amd/display: Check if PSR enabled when entering MALL [Description] - When attempting to enter MALL SS when a PSR panel is connected, we have to check that the PSR panel has already entered PSR because the vsync interrupt call is per display index (can be called for the non-PSR panel first) - Also don't override link settings when programming phantom stream (main and phantom pipe share the same link) Reviewed-by: Jun Lei Acked-by: Brian Chang Signed-off-by: Alvin Lee Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c b/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c index c5380ce706535..913a1fe6b3daf 100644 --- a/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c +++ b/drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c @@ -1561,8 +1561,13 @@ static enum dc_status apply_single_controller_ctx_to_hw( pipe_ctx->plane_res.scl_data.lb_params.alpha_en = pipe_ctx->bottom_pipe != NULL; - pipe_ctx->stream->link->psr_settings.psr_feature_enabled = false; - + /* Phantom and main stream share the same link (because the stream + * is constructed with the same sink).
