qxl: make qxl_render_update async
RHBZ# 747011 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, as part of the QXLCookie. The implementation uses interface_update_area_complete with a bh to make sure dpy_update and qxl_flip are called from the io thread, otherwise the vga->ds->surface.data can change under our feet. With this patch sdl+spice works fine. But spice by itself doesn't produce the expected screendumps unless repeated a few times, due to ppm_save being called before update_area (rendering done in spice server thread) having a chance to complete. Fixed by next patch, but see commit message for problem introduced by it. Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
