There's two major things this patchset does: - Add drm_dp_mst_connector_atomic_check() so drivers don't need to use ->best_encoder() to prevent modesets on zombie MST connectors. We'll use this later for implementing MST fallback retraining as well. - Fix DPMS on->off changes failing with legacy modesetting users after an MST connector's topology has disappeared, which resulted in CRTCs being left on when they shouldn't have been Lyude Paul (6): drm/dp_mst: Introduce drm_dp_mst_connector_atomic_check() drm/nouveau: Unbreak nv50_mstc->best_encoder() drm/i915: Leave intel_conn->mst_port set, use mst_port_gone instead drm/i915: Skip vcpi allocation for MSTB ports that are gone drm/i915: Fix intel_dp_mst_best_encoder() drm/amdgpu/dm/mst: Use drm_dp_mst_connector_atomic_check() .../display/amdgpu_dm/amdgpu_dm_mst_types.c | 12 +++ drivers/gpu/drm/drm_dp_mst_topology.c | 76 +++++++++++++++++++ drivers/gpu/drm/i915/intel_dp_mst.c | 46 ++++++----- drivers/gpu/drm/i915/intel_drv.h | 1 + drivers/gpu/drm/nouveau/dispnv50/disp.c | 25 +++--- include/drm/drm_dp_mst_helper.h | 3 + 6 files changed, 132 insertions(+), 31 deletions(-) -- 2.17.1
