drm_send_event — send DRM event to file descriptor
void drm_send_event ( | struct drm_device * dev, |
struct drm_pending_event * e) ; |
This function sends the event e
, initialized with drm_event_reserve_init
,
to its associated userspace DRM file. This function acquires dev->event_lock,
see drm_send_event_locked
for callers which already hold this lock.
Note that the core will take care of unlinking and disarming events when the corresponding DRM file is closed. Drivers need not worry about whether the DRM file for this event still exists and can call this function upon completion of the asynchronous work unconditionally.
