From: Andrey Grodzovsky Date: Fri, 21 Jul 2017 20:34:36 +0000 (-0400) Subject: drm/amd/display: Move stream validations into seperate function. X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9345d9874c324b2f8cce79d4de11f27ae1ef80e9;p=openwrt%2Fstaging%2Fblogic.git drm/amd/display: Move stream validations into seperate function. Stateless streams validations (not require resource population) moved into hook to be called directly from DM. Call dc_validate_stream be before validate_with_context for non Linux APIs Signed-off-by: Andrey Grodzovsky Reviewed-by: Harry Wentland Reviewed-by: Tony Cheng Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/display/dc/core/dc.c b/drivers/gpu/drm/amd/display/dc/core/dc.c index 79218805754e..9c2faf8e4b14 100644 --- a/drivers/gpu/drm/amd/display/dc/core/dc.c +++ b/drivers/gpu/drm/amd/display/dc/core/dc.c @@ -664,6 +664,20 @@ static bool is_validation_required( return false;
