X-Received-From: 209.132.183.28 Subject: [Qemu-devel] [PATCH v2 2/2] qxl: make qxl_render_update async X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org RHBZ# 794658 Removes the last user of QXL_SYNC when using update drivers that use the _ASYNC io ports. The last user is qxl_render_update, it is called both by qxl_hw_update which is the vga_hw_update_ptr passed to graphic_console_init, and by qxl_hw_screen_dump. At the same time the QXLRect area being passed to the red_worker thread is passed as a copy, allocated and copied before passing, deallocated on the interface_async_complete callback.
