[0/9] drm/i915/dp_mst: Fix MST payload removal during output disabling

Message

Imre Deak Jan. 25, 2023, 11:48 a.m. UTC

This patchset fixes a payload tracking issue in the MST encoder's
disabling hook and adds verification for the related sw and sink state.
It also factors out a few functions to modeset CRTCs and connectors
during the atomic check phase to make it clearer where this is done.

Tested on ICL and ADLP.

Imre Deak (9):
  drm/i915/dp_mst: Add the MST topology state for modesetted CRTCs
  drm/display/dp_mst: Handle old/new payload states in
    drm_dp_remove_payload()
  drm/display/dp_mst: Add drm_atomic_get_old_mst_topology_state()
  drm/i915/dp_mst: Fix payload removal during output disabling
  drm/display/dp_mst: Fix the payload VCPI check in
    drm_dp_mst_dump_topology()
  drm/i915: Factor out helpers for modesetting CRTCs and connectors
  drm/i915/dp_mst: Move getting the MST topology state earlier to
    connector check
  drm/display/dp_mst: Add a helper to verify the MST payload state
  drm/i915/dp_mst: Verify the MST state of modesetted outputs
