From 0417df1699406a8909088152b9bd46e1c2297bbe Mon Sep 17 00:00:00 2001 From: Bayan Zabihiyan Date: Mon, 19 Aug 2019 15:18:43 -0400 Subject: drm/amd/display: Isolate DSC module from driver dependencies [Why] Edid Utility wishes to include DSC module from driver instead of doing it's own logic which will need to be updated every time someone modifies the driver logic. [How] Modify some functions such that we dont need to pass the entire DC structure as parameter. -Remove DC inclusion from module. -Filter out problematic types and inclusions Signed-off-by: Bayan Zabihiyan Reviewed-by: Jun Lei Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 3 +- drivers/gpu/drm/amd/display/dc/dc_dsc.h | 14 ++++- drivers/gpu/drm/amd/display/dc/dc_hw_types.h | 57 +++++++++-------- drivers/gpu/drm/amd/display/dc/dc_types.h | 9 +++ drivers/gpu/drm/amd/display/dc/dsc/dc_dsc.c | 75 +++++++++++++++++++---- drivers/gpu/drm/amd/display/dc/inc/hw/dsc.h | 12 ++-- 6 files changed, 125 insertions(+), 45 deletions(-) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index 4bf36032eadb..130da9f1b1dd 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -3622,8 +3622,9 @@ create_stream_for_sink(struct amdgpu_dm_connector *aconnector, dc_link_get_link_cap(aconnector->dc_link));
