Subject: [PATCH v10 3/3] eventdev: add atomic atq to test-eventdev app
Date: Thu, 6 Mar 2025 09:49:46 +0100 [thread overview]
Message-ID: <20250306084946.3699972-4-luka.jankovic@ericsson.com> (raw)
In-Reply-To: <20250306084946.3699972-1-luka.jankovic@ericsson.com>
Add an atomic atq test to the test-eventdev app. The test works
in the same way as atomic queue, the difference being that only one
queue capable of all types for both stages.
