[WHY] Current implementation of pipe split policy prevents pipe split with multiple displays connected, which caused the MCLK speed to be stuck at max [HOW] Changed the pipe split policies so that pipe split is allowed for multi-display configurations Reviewed-by: Aric Cyr <Aric.Cyr@xxxxxxx> Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx> Signed-off-by: Angus Wang <angus.wang@xxxxxxx> --- drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c | 2 +- drivers/gpu/drm/amd/display/dc/dcn201/dcn201_resource.c | 2 +- drivers/gpu/drm/amd/display/dc/dcn21/dcn21_resource.c | 2 +- drivers/gpu/drm/amd/display/dc/dcn30/dcn30_resource.c | 2 +- drivers/gpu/drm/amd/display/dc/dcn301/dcn301_resource.c | 2 +- drivers/gpu/drm/amd/display/dc/dcn302/dcn302_resource.c | 2 +- drivers/gpu/drm/amd/display/dc/dcn303/dcn303_resource.c | 2 +- drivers/gpu/drm/amd/display/dc/dcn31/dcn31_resource.c | 2 +- 8 files changed, 8 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c index 2a72517e2b28..2bc93df023ad 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c +++ b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c @@ -1069,7 +1069,7 @@ static const struct dc_debug_options debug_defaults_drv = { .timing_trace = false, .clock_trace = true, .disable_pplib_clock_request = true, -
