From fb55546ea4b50f04ef41c196b8ac1824e26bc48c Mon Sep 17 00:00:00 2001 From: Anthony Koo Date: Sun, 20 Jan 2019 01:23:07 -0500 Subject: [PATCH] drm/amd/display: refactor init_hw to isolate pipe related init [Why] Pipe related init is possible to optimized if we know what we intend to program, and if we can determine it matches what is already programmed for the pipe. [How] First step is to isolate the pipe related init code Signed-off-by: Anthony Koo Reviewed-by: Aric Cyr Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher --- .../amd/display/dc/dce110/dce110_hw_sequencer.c | 6 + .../drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c | 159 ++++++++++----------- drivers/gpu/drm/amd/display/dc/inc/hw_sequencer.h | 2 + 3 files changed, 85 insertions(+), 82 deletions(-) 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 a438634..4df8a43 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 @@ -2275,6 +2275,11 @@ static void dce110_enable_per_frame_crtc_position_reset( } +static void init_pipes(struct dc *dc, struct dc_state *context) +{ + // Do nothing +} + static void init_hw(struct dc *dc) { int i;
