Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

DrmFd

open a non-master fd for this DRM node

The compositor will send this event when the wp_drm_lease_device_v1 global is bound, although there are no guarantees as to how long this takes - the compositor might need to wait until regaining DRM master. The included fd is a non-master DRM file descriptor opened for this device and the compositor must not authenticate it. The purpose of this event is to give the client the ability to query DRM and discover information which may help them pick the appropriate DRM device or select the appropriate connectors therein.

Fields

§fd: OwnedFd

DRM file descriptor

§

Connector

advertise connectors available for leases

The compositor will use this event to advertise connectors available for lease by clients. This object may be passed into a lease request to indicate the client would like to lease that connector, see wp_drm_lease_request_v1.request_connector for details. While the compositor will make a best effort to not send disconnected connectors, no guarantees can be made.

The compositor must send the drm_fd event before sending connectors. After the drm_fd event it will send all available connectors but may send additional connectors at any time.

§

Done

signals grouping of connectors

The compositor will send this event to indicate that it has sent all currently available connectors after the client binds to the global or when it updates the connector list, for example on hotplug, drm master change or when a leased connector becomes available again. It will similarly send this event to group wp_drm_lease_connector_v1.withdrawn events of connectors of this device.

§

Released

the compositor has finished using the device

This event is sent in response to the release request and indicates that the compositor is done sending connector events. The compositor will destroy this object immediately after sending the event and it will become invalid. The client should release any resources associated with this device after receiving this event.

This is a destructor, once received this object cannot be used any longer.
