Subject: [PATCH 0/4] Unregister mst connectors when hotplug
Date: Wed, 21 Jul 2021 00:03:38 +0800 [thread overview]
Message-ID: <20210720160342.11415-1-Wayne.Lin@amd.com> (raw)
By patches below, we change to clean up resources of a mst connector
and put port's malloc_kref when we start to destroy a connector.
* 09b974e8983 drm/amd/amdgpu_dm/mst: Remove ->destroy_connector() callback
* 72dc0f51591 drm/dp_mst: Remove drm_dp_mst_topology_cbs.destroy_connector
However, find out that mst connectors won't reach connector destroy flow
after hot unplug and hence will cause no more resources for new added
connectors. Thus, this patch set is trying to solve observed
registration/unregistration problem of mst connectors.
Wayne Lin (4):
drm/dp_mst: Put malloc_kref of vcpi pointing port when disable MST
drm/dp_mst: Only create connector for connected end device
drm/dp_mst: Put connector of disconnected end device when handling CSN
drm/dp_mst: Release disconnected connectors when resume
