From 2d0db3d83f6b28f613bf5546145f5b57a5b83aca Mon Sep 17 00:00:00 2001 From: Jun Lei Date: Wed, 3 Jul 2019 16:52:38 -0400 Subject: [PATCH 3080/4256] drm/amd/display: populate last calculated bb state with max clocks [why] update_bounding_box calculates intermediate bb states based on clock relationship however, the last state doesn't need to maintain a minimum relationship, but should actually contain maximum of every clock. otherwise maximum clocks are not usable [how] once the calculated bb is built, override the last state with max values Signed-off-by: Jun Lei Reviewed-by: Aric Cyr Acked-by: Leo Li --- drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c | 4 ++++ 1 file changed, 4 insertions(+) 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 296bc7e4c4a2..193270ba60e6 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c +++ b/drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c @@ -2746,6 +2746,10 @@ static void update_bounding_box(struct dc *dc, struct _vcs_dpi_soc_bounding_box_ num_calculated_states++; } + calculated_states[num_calculated_states - 1].socclk_mhz = max_clocks->socClockInKhz / 1000; + calculated_states[num_calculated_states - 1].fabricclk_mhz = max_clocks->socClockInKhz / 1000; + calculated_states[num_calculated_states - 1].dcfclk_mhz = max_clocks->dcfClockInKhz / 1000; + memcpy(bb->clock_limits, calculated_states, sizeof(bb->clock_limits)); bb->num_states = num_calculated_states; -- 2.17.1
