      drm/amd/dm/mst: Ignore payload update failures · 58fe03d6
      Lyude Paul authored
      Disabling a display on MST can potentially happen after the entire MST
      topology has been removed, which means that we can't communicate with
      the topology at all in this scenario. Likewise, this also means that we
      can't properly update payloads on the topology and as such, it's a good
      idea to ignore payload update failures when disabling displays.
      Currently, amdgpu makes the mistake of halting the payload update
      process when any payload update failures occur, resulting in leaving
      DC's local copies of the payload tables out of date.
      
      This ends up causing problems with hotplugging MST topologies, and
      causes modesets on the second hotplug to fail like so:

      Note as well, I have only been able to reproduce this on setups with 2
      MST displays.
      
      Changes since v1:
      * Don't return false when part 1 or part 2 of updating the payloads
        fails, we don't want to abort at any step of the process even if
        things fail

      drm/amdgpu: update default voltage for boot od table for navi1x · 7b913a76
      Alex Deucher authored
      It needed to be updated as well so it will show the proper values
      if you reset to the defaults.
