| H A D | ivpu_ipc.c | diff b563e47957af4ff71736c5cc4120a59b055ab583 Thu May 25 12:38:18 CEST 2023 Stanislaw Gruszka <stanislaw.gruszka@linux.intel.com> accel/ivpu: Do not use mutex_lock_interruptible
If we get signal when waiting for the mmu->lock we do not invalidate
current MMU configuration that might result in undefined behavior.
Additionally there is little or no benefit on break waiting for
ipc->lock. In current code base, we keep this lock for short periods.
