Date: Thu, 28 Oct 2021 13:58:49 +0100 Message-Id: <20211028125855.3281674-5-matthew.auld@intel.com> X-Mailer: git-send-email 2.26.3 In-Reply-To: <20211028125855.3281674-1-matthew.auld@intel.com> References: <20211028125855.3281674-1-matthew.auld@intel.com> MIME-Version: 1.0 X-BeenThere: dri-devel@lists.freedesktop.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Direct Rendering Infrastructure - Development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dri-devel-bounces@lists.freedesktop.org Sender: "dri-devel" From: Maarten Lankhorst This allows us to finally get rid of all the assumptions that vma->obj is NULL. Changes since v1: - Ensure the mock_ring vma is pinned to prevent a fault. - Pin it high to avoid failure in evict_for_vma selftest.
