Subject: [PATCH v2 03/37] baseband/acc100: add function to check AQ availability
Date: Fri, 19 Aug 2022 19:31:23 -0700	[thread overview]
Message-ID: <20220820023157.189047-4-hernan.vargas@intel.com> (raw)
In-Reply-To: <20220820023157.189047-1-hernan.vargas@intel.com>

It is possible for some corner case to run more batch enqueue than
supported. A protection is required to avoid that corner case.
Enhance all ACC100 enqueue operations with check to see if there is room
in the atomic queue for enqueueing batches into the queue manager
Check room in AQ for the enqueues batches into Qmgr
