/** Return busy status (1 if busy, 0 if idle).
* The high word is used to indicate on which rings the object
* currently resides:
* 16:31 - busy (r or r/w) rings (16 render, 17 bsd, 18 blt, etc)
/** Return busy status
*
* A return of 0 implies that the object is idle (after
* having flushed any pending activity), and a non-zero return that
* the object is still in-flight on the GPU. (The GPU has not yet
* signaled completion for all pending requests that reference the
* object.)
*
* The returned dword is split into two fields to indicate both
* the engines on which the object is being read, and the
* engine on which it is currently being written (if any).
*
* The low word (bits 0:15) indicate if the object is being written
* to by any engine (there can only be one, as the GEM implicit
* synchronisation rules force writes to be serialised). Only the
* engine for the last write is reported.
*
* The high word (bits 16:31) are a bitmask of which engines are
* currently reading from the object. Multiple engines may be
* reading from the object simultaneously.
*
* The value of each engine is the same as specified in the
* EXECBUFFER2 ioctl, i.e. I915_EXEC_RENDER, I915_EXEC_BSD etc.
* Note I915_EXEC_DEFAULT is a symbolic value and is mapped to
* the I915_EXEC_RENDER engine for execution, and so it is never
* reported as active itself. Some hardware may have parallel
* execution engines, e.g. multiple media engines, which are
* mapped to the same identifier in the EXECBUFFER2 ioctl and
* so are not separately reported for busyness.
