[PATCH v2 0/2] Fix observed mst problems with StarTech hub

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use Startech 1to3 DP hub to do some mst hotplug tests and find some
light up issues.

1. ACT polling timeout:
   Which is due to we didn't update DPCD payload table but still try
   to send ACT and polling for "ACT Handled" bit
2. Not all monitors light up:
   Due to we wrongly set unavailable VCP ID for new streams

Changes since v1:
* Add appropriate tags: Fixes & Cc
* Change debug macro to use drm_dbg_kms() instead

Wayne Lin (2):
  drm/dp_mst: Do not set proposed vcpi directly
  drm/dp_mst: Avoid to mess up payload table by ports in stale topology
