Reg. #1134945 - Pipers Way, Swindon SN3 1RJ Subject: [Intel-gfx] [PATCH v4 i-g-t 09/15] tests/i915/i915_hangman: Remove reliance on context persistance X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Intel-GFX@Lists.FreeDesktop.Org Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" From: John Harrison The hang test was relying on context persitence for no particular reason. That is, it would set a bunch of background spinners running then immediately destroy the active contexts but expect the spinners to keep spinning. With the current implementation of context persistence in i915, that means that super high priority pings are sent to each engine at the start of the test. Depending upon the timing and platform, one of those unexpected pings could cause test failures. There is no need to require context persitence in this test. So change to managing the contexts cleanly and only destroying them when they are no longer in use.
