|
*
|

|
* This protocol is used by Wayland compositors which act as Direct
|
||||||
|
* Rendering Manager (DRM) masters to lease DRM resources to Wayland
|
||||||
|
* clients.
|
||||||
|
*
|
||||||
|
* The compositor will advertise one wp_drm_lease_device_v1 global for each
|
||||||
|
* DRM node. Some time after a client binds to the wp_drm_lease_device_v1
|
||||||
|
* global, the compositor will send a drm_fd event followed by zero, one or
|
||||||
|
* more connector events. After all currently available connectors have been
|
||||||
|
* sent, the compositor will send a wp_drm_lease_device_v1.done event.
|
||||||
|
*
|
||||||
|
* When the list of connectors available for lease changes the compositor
|
||||||
|
* will send wp_drm_lease_device_v1.connector events for added connectors and
|
||||||
|
* wp_drm_lease_connector_v1.withdrawn events for removed connectors,
|
||||||
|
* followed by a wp_drm_lease_device_v1.done event.
|
||||||
|
*
|
||||||
|
* The compositor will indicate when a device is gone by removing the global
|
||||||
|
* via a wl_registry.global_remove event. Upon receiving this event, the
|
||||||
|
* client should destroy any matching wp_drm_lease_device_v1 object.
|
||||||
|
*
|
||||||
|
* To destroy a wp_drm_lease_device_v1 object, the client must first issue
|
||||||
|
* a release request. Upon receiving this request, the compositor will
|
||||||
|
* immediately send a released event and destroy the object. The client must
|
||||||
|
* continue to process and discard drm_fd and connector events until it
|
||||||
|
* receives the released event. Upon receiving the released event, the
|
||||||
|
* client can safely cleanup any client-side resources.
|
||||||
|
*
|
||||||
|
* Warning! The protocol described in this file is currently in the testing
|
||||||
|
* phase. Backward compatible changes may be added together with the
|
||||||
|
* corresponding interface version bump. Backward incompatible changes can
|
||||||
|
* only be done by creating a new major version of the extension.

<description summary="lease device">
|
||||||
|
This protocol is used by Wayland compositors which act as Direct
|
||||||
|
Rendering Manager (DRM) masters to lease DRM resources to Wayland
|
||||||
|
clients.
|
||||||
|
|
||||||
|
The compositor will advertise one wp_drm_lease_device_v1 global for each
|
||||||
|
DRM node. Some time after a client binds to the wp_drm_lease_device_v1
|
||||||
|
global, the compositor will send a drm_fd event followed by zero, one or
|
||||||
|
more connector events. After all currently available connectors have been
|
||||||
|
sent, the compositor will send a wp_drm_lease_device_v1.done event.
|
||||||
|
|
||||||
|
When the list of connectors available for lease changes the compositor
|
||||||
|
will send wp_drm_lease_device_v1.connector events for added connectors and
|
||||||
|
wp_drm_lease_connector_v1.withdrawn events for removed connectors,
|
||||||
|
followed by a wp_drm_lease_device_v1.done event.
|
||||||
|
|
||||||
|
The compositor will indicate when a device is gone by removing the global
|
||||||
|
via a wl_registry.global_remove event. Upon receiving this event, the
|
||||||
|
client should destroy any matching wp_drm_lease_device_v1 object.
|
||||||
|
|
||||||
|
To destroy a wp_drm_lease_device_v1 object, the client must first issue
|
||||||
|
a release request. Upon receiving this request, the compositor will
|
||||||
|
immediately send a released event and destroy the object. The client must
|
||||||
|
continue to process and discard drm_fd and connector events until it
|
||||||
|
receives the released event. Upon receiving the released event, the
|
||||||
|
client can safely cleanup any client-side resources.
|
||||||
|
|
||||||
|
Warning! The protocol described in this file is currently in the testing
|
||||||
|
phase. Backward compatible changes may be added together with the
|
||||||
|
corresponding interface version bump. Backward incompatible changes can
|
||||||
|
only be done by creating a new major version of the extension.

The included fd is a non-master DRM file descriptor opened for this

The purpose of this event is to give the client the ability to
