Subject: [PATCH v2 0/7] drm: add per-connector hotplug events
Date: Wed, 09 Jun 2021 21:23:19 +0000 [thread overview]
Message-ID: <s5D1m6hjidKxuxaN6qpewqhxco48P4poVuMf1zi4qA@cp3-web-012.plabs.ch> (raw)
When a uevent only updates a single connector, add a CONNECTOR property
to the uevent. This allows user-space to ignore other connectors when
handling the uevent. This is purely an optimization, drivers can still
send a uevent without the CONNECTOR property.
The CONNECTOR property is already set when sending HDCP property update
uevents, see drm_sysfs_connector_status_event.
This has been tested with a wlroots patch [1].
amdgpu and the probe-helper has been updated to use these new fine-grained
uevents.
