[Why] In order to give pin notifications to the sound driver from DM we need to know whether audio is enabled on a stream and what pin it's using from DC. [How] Expose the instance via stream status if it's a mapped resource for the stream. It will be -1 if there's no audio mapped.

The cp hang occurs in OCL conformance test only on supermicro platform which has 40 cores and the test generates 40 threads. The root cause is race condition in non-protected flags. The fix is to add flags of is_evicted and is_active(init_mqd()) into protected area. Signed-off-by:

This RELEASE_MEM use has the Release semantic, which means we should write back but not invalidate. Invalidations only make sense with the Acquire semantic (ACQUIRE_MEM), or when RELEASE_MEM is used to do the combined Acquire-Release semantic, which is a barrier, not a fence. The undesirable side effect of doing invalidations for the Release semantic is that it invalidates caches while shaders are running, because the Release can execute in the middle of the next IB. UMDs should use ACQUIRE_MEM at the beginning of IBs. Doing cache invalidations for a fence (like in this case) doesn't do anything for correctness. Signed-off-by:

kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memcpy, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes.
