There different types of BOs are supported:
- shmem
A user application uses shmem BOs as input/output for its workload running
on NPU.
- device memory heap
The fixed size buffer dedicated to the device.
- device buffer
The buffer object allocated from device memory heap.
- command buffer
The buffer object created for delivering commands. The command buffer
object is small and pinned on creation.
New IOCTLs are added: CREATE_BO, GET_BO_INFO, SYNC_BO. SYNC_BO is used
to explicitly flush CPU cache for BO memory.
