Subject: [PATCH v2 0/4] drm/dp_mst: drm_dp_check_act_status() fixes
Date: Mon, 6 Apr 2020 18:12:49 -0400 [thread overview]
Message-ID: <20200406221253.1307209-1-lyude@redhat.com> (raw)
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
