drm/dp_mst: Fix resetting msg rx state after topology removal

2024-12-05T14:18:07Z

If the MST topology is removed during the reception of an MST down reply or MST up request sideband message, the drm_dp_mst_topology_mgr::up_req_recv/down_rep_recv states could be reset from one thread via drm_dp_mst_topology_mgr_set_mst(false), racing with the reading/parsing of the message from another thread via drm_dp_mst_handle_down_rep() or drm_dp_mst_handle_up_req(). The race is possible since the reader/parser doesn't hold any lock while accessing the reception state. This in turn can lead to a memory corruption in the reader/parser as described by commit bd2fccac61b4 ("drm/dp_mst: Fix MST sideband message body length check"). Fix the above by resetting the message reception state if needed before reading/parsing a message. Another solution would be to hold the drm_dp_mst_topology_mgr::lock for the whole duration of the message reception/parsing in drm_dp_mst_handle_down_rep() and drm_dp_mst_handle_up_req(), however this would require a bigger change. Since the fix is also needed for stable, opting for the simpler solution in this patch.

drm/i915/gsc: ARL-H and ARL-U need a newer GSC FW.

2024-11-12T07:44:55Z

All MTL and ARL SKUs share the same GSC FW, but the newer platforms are only supported in newer blobs. In particular, ARL-S is supported starting from 102.0.10.1878 (which is already the minimum required version for ARL in the code), while ARL-H and ARL-U are supported from 102.1.15.1926. Therefore, the driver needs to check which specific ARL subplatform its running on when verifying that the GSC FW is new enough for it.

drm/tests: helpers: Add helper for drm_display_mode_from_cea_vic()

As Maxime suggested, add a new helper drm_kunit_display_mode_from_cea_vic(), it can replace the direct call of drm_display_mode_from_cea_vic(), and it will help solving the `mode` memory leaks.
