Related-To: NEO-12197 Currently for new resources user thread must wait before submitting actual workload. With this commit, instead of waiting on user thread, request is sent to background ULLS controller thread and additional semaphore is programmed. ULLS controller will perform actual wait and signal semaphore when paging fence reaches required value. Signed-off-by: Szymon Morek <szymon.morek@intel.com>
