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.
