[PATCH v4 0/6] drm: add per-connector hotplug events

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
