#define DRM_VMW_EVENT_FENCE_SIGNALED   0x80000000

DRM_VMW_FENCE_EVENT

Queues an event on a fence to be delivered on the drm character device when the fence has signaled the DRM_VMW_FENCE_FLAG_EXEC flag. Optionally the approximate time when the fence signaled is given by the event.

#define DRM_VMW_EXECBUF_VERSION   1

DRM_VMW_UNREF_SURFACE - Unreference a host surface.

Clear a reference previously put on a host surface. When all references are gone, including the one implicitly placed on creation, a destroy surface command will be queued for the host. Does not wait for completion. DRM_VMW_EXECBUF

Submit a command buffer for execution on the host, and return a fence seqno that when signaled, indicates that the command buffer has executed. struct drm_vmw_execbuf_arg

: User-space address of a command buffer cast to an uint64_t. -size: Size in bytes of the command buffer. -us: Sleep until software is less than microseconds ahead of hardware. The driver may round this value to the nearest kernel tick. : User-space address of a struct drm_vmw_fence_rep cast to an uint64_t.

Version

: Allows expanding the execbuf ioctl parameters without breaking backwards compatibility, since user-space will always tell the kernel which version it uses. : Execbuf flags. None currently.

Argument to the DRM_VMW_EXECBUF Ioctl.

DRM_VMW_FENCE_WAIT

Waits for a fence object to signal. The wait is interruptible, so that signals may be delivered during the interrupt. The wait may timeout, in which case the calls returns -EBUSY. If the wait is restarted, that is restarting without resetting to zero, the timeout is computed from the first call.

The flags argument to the DRM_VMW_FENCE_WAIT ioctl indicates what to wait on: DRM_VMW_FENCE_FLAG_EXEC: All commands ahead of the fence in the command stream have executed. DRM_VMW_FENCE_FLAG_QUERY: All query results resulting from query finish commands in the buffer given to the EXECBUF ioctl returning the fence object handle are available to user-space.

DRM_VMW_WAIT_OPTION_UNREF: If this wait option is given, and the fenc wait ioctl returns 0, the fence object has been unreferenced after the wait.
