      drm/nouveau: Fix nv50_mstc->best_encoder() · e87b0bbc
      Lyude Paul authored
      As mentioned in the previous commit, we currently prevent new modesets
      on recently-removed MST connectors by returning no encoder from our
      ->best_encoder() callback once the MST port has disappeared. This is
      wrong however, because it prevents legacy modesetting users from being
      able to disable CRTCs on MST connectors after the connector's respective
      topology has disappeared.
      
      So, fix this by instead by just always returning a valid encoder.
      
      Changes since v2:
      - Remove usage of atomic MST helper for now, since that got replaced
        with a much simpler solution

      drm/atomic_helper: Allow DPMS On<->Off changes for unregistered connectors · b5d29843
      Lyude Paul authored
      It appears when testing my previous fix for some of the legacy
      modesetting issues with MST, I misattributed some kernel splats that
      started appearing on my machine after a rebase as being from upstream.
      But it appears they actually came from my patch series:

      [    2.980884] ---[ end trace 5eb47a76277d4731 ]---
      
      The cause of this appears to be due to the fact that if there's
      pre-existing display state that was set by the BIOS when i915 loads, it
      will attempt to perform a modeset before the driver is registered with
      userspace. Since this happens before the driver's registered with
      userspace, it's connectors are also unregistered and thus-states which
      would turn on DPMS on a connector end up getting rejected since the
      connector isn't registered.
      
      These bugs managed to get past Intel's CI partially due to the fact it
      never ran a full test on my patches for some reason, but also because
      all of the tests unload the GPU once before running. Since this bug is
      only really triggered when the drivers tries to perform a modeset before
      it's been fully registered with userspace when coming from whatever
      display configuration the firmware left us with, it likely would never
      have been picked up by CI in the first place.
      
      After some discussion with vsyrjala, we decided the best course of
      action would be to just move the unregistered connector checks out of
      update_connector_routing() and into drm_atomic_set_crtc_for_connector().
      The reason for this being that legacy modesetting isn't going to be
      expecting failures anywhere (at least this is the case with X), so
      ideally we want to ensure that any DPMS changes will still work even on
      unregistered connectors. Instead, we now only reject new modesets which
      would change the current CRTC assigned to an unregistered connector
      unless no new CRTC is being assigned to replace the connector's previous
      one.
