[PATCH v2 0/4] drm/dp_mst: drm_dp_check_act_status() fixes

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

 



Noticed this while fixing some unrelated issues with NAKs being dropped
- we don't wait nearly long enough to receive ACTs from MST hubs in some
situations. Also, we take the time to refactor this function a bit.

This fixes some ACT timeouts I observed on an EVGA MST hub with i915.

Lyude Paul (4):
  drm/dp_mst: Improve kdocs for drm_dp_check_act_status()
  drm/dp_mst: Reformat drm_dp_check_act_status() a bit
  drm/dp_mst: Increase ACT retry timeout to 3s
  drm/dp_mst: Print errors on ACT timeouts
