Subject: [PATCH v4 0/6] drm: add per-connector hotplug events
Date: Mon, 18 Oct 2021 08:47:09 +0000 [thread overview]
Message-ID: <20211018084707.32253-1-contact@emersion.fr> (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.
Changes in v4: address comments from Ville, Maxime and Sam.
Simon Ser (6):
drm/sysfs: introduce drm_sysfs_connector_hotplug_event
drm/probe-helper: add drm_kms_helper_connector_hotplug_event
drm/connector: use drm_sysfs_connector_hotplug_event
amdgpu: use drm_kms_helper_connector_hotplug_event
drm/probe-helper: use drm_kms_helper_connector_hotplug_event
i915/display/dp: send a more fine-grained link-status uevent
