DMA flags

Warning:
These values must match xf86drm.h.
See also:
drm_dma.
Enumerator:
_DRM_DMA_BLOCK  Block until buffer dispatched.

Note:
The buffer may not yet have been processed by the hardware -- getting a hardware lock with the hardware quiescent will ensure that the buffer has been processed.
_DRM_DMA_WHILE_LOCKED  Dispatch while lock held
_DRM_DMA_PRIORITY  High priority dispatch
_DRM_DMA_WAIT  Wait for free buffers
_DRM_DMA_SMALLER_OK  Smaller-than-requested buffers OK
_DRM_DMA_LARGER_OK  Larger-than-requested buffers OK
