[PATCH 18/27] drm/amd/display: Enable "trigger_hotplug" debugfs on all outputs

Anson Jacob Anson.Jacob at amd.com
Fri Jan 29 21:27:43 UTC 2021


From: Stylon Wang <stylon.wang at amd.com>

[Why]
Per-connector debugfs entry "trigger_hotplug" is available on DP/eDP only.
New IGT tests need this entry to test other outputs.

[How]
Enable this debugfs entry on all types of connectors
