From: Wyatt Wood Date: Thu, 6 May 2021 20:11:16 +0000 (-0400) Subject: drm/amd/display: Refactor and add visual confirm for HW Flip Queue X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3ca402375a2197579d1029e7fa9d856847fe0e7b;p=linux.git drm/amd/display: Refactor and add visual confirm for HW Flip Queue [Why] Visual confirm will indicate if driver is programming the surface address. Refactor is required because much of the visual confirm logic is buried deep in the mpcc files. In addition, visual confirm is not updated during fast updates. [How] In order to have visual confirm for driver flips, visual confirm needs to be updated on every frame, including fast updates. Add a new hw sequencer interface update_visual_confirm_color, and a new mpc function pointer set_bg_color. v2: drop unused variable (Alex) Signed-off-by: Wyatt Wood Reviewed-by: Aric Cyr Acked-by: Stylon Wang Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c index 8f11e2b58cd72..81803463ca9bc 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c +++ b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c @@ -2502,9 +2502,25 @@ static void dcn10_update_dpp(struct dpp *dpp, struct dc_plane_state *plane_state dpp->funcs->dpp_program_bias_and_scale(dpp, &bns_params);
