Function Documentation

int vmw_event_fence_action_queue	(	struct drm_file *	file_priv,
		struct vmw_fence_obj *	fence,
		struct drm_pending_event *	event,
		uint32_t *	tv_sec,
		uint32_t *	tv_usec,
		bool	interruptible
	)

vmw_event_fence_action_create - Post an event for sending when a fence object seqno has passed.

: The file connection on which the event should be posted. : The fence object on which to post the event. : Event to be posted. This event should've been alloced using k[mz]alloc, and should've been completely initialized. : Interruptible waits if possible.

As a side effect, the object pointed to by may have been freed when this function returns. If this function returns with an error code, the caller needs to free that object.

void vmw_event_fence_fpriv_gone	(	struct vmw_fence_manager *	fman,

vmw_event_fence_fpriv_gone - Remove references to struct drm_file objects

: Pointer to a struct vmw_fence_manager : Pointer to linked list of struct vmw_event_fence_action objects with pointers to a struct drm_file object about to be closed.

This function removes all pending fence events with references to a specific struct drm_file object about to be closed. The caller is required to pass a list of all struct vmw_event_fence_action objects with such events attached. This function is typically called before the struct drm_file object's event management is taken down.
