drm/amd/display: disable SubVP + DRR to prevent underflow

2023-02-16T03:26:22+00:00

[Why&How] Temporarily disable SubVP+DRR since Xorg has an architectural limitation where freesync will not work in a multi monitor configuration. SubVP+DRR requires that freesync be working. Whether OS has variable refresh setting enabled or not, the state on the crtc remains same unless an application requests VRR. Due to this, there is no way to know whether freesync will actually work or not while we are on the desktop from the kernel's perspective. If userspace does not have a limitation with multi-display freesync (for example wayland), then this feature can be enabled by adding a dcfeaturemask option to amdgpu on the kernel cmdline like: amdgpu.dcfeaturemask=0x200 Signed-off-by: Aurabindo Pillai Reviewed-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: move public dc link function implementation to dc_link_exports

2023-02-14T21:06:28+00:00

[why] Link is a subcomponent in dc. DM should be aware of dc link structure as one of the abstracted objects maintained by dc. However it should have no idea of the existence of a link component in dc dedicated to maintain the states of dc link structure. As such we are moving link interfaces out of dc_link.h and directly added to dc.h. We are grandually fading out the explicit inclusion of dc_link header and eventually delete it. On dc side, since link is a subcomponent behind dc interfaces, it is not a good idea to implement dc interfaces in each individual subcomponent of link which is already a subcomponent of dc. So we are decoupling it by implementing a dc_link_exports in dc. This file will be a thin translation layer that breaks the dependency so link is able to make interface changes without breaking DM.

drm/amd/display: Extract temp drm mst deallocation wa into its own function

2023-02-14T21:03:35+00:00

[why] A recent change was made to implement temporary workaround due DRM update in MST interfaces. The workaround is added into our generic deallocation MST sequence. This ticket is to extract this temporary workaround into its own function so it is differentiated from our generic sequence.
