Simon Ser e89cf5f047 backend/drm: use atomic test-only commits for modifier fallback ... Instead of trying to perform a real modeset in init_renderer, perform an atomic test-only commit to find out whether disabling modifiers is necessary because of bandwidth limitations. This decouples init_renderer from the actual commit, making it possible to modeset an output with a user-supplied buffer instead of a black frame. We loose the ability to make sure the buffers coming from the swapchain will work fine when using the legacy interface. This can break i915 when atomic is disabled and modifiers enabled. But i915 always has atomic (so the user must explicitly disable it to run into potential bandwidth limitations) and is the only known problematic driver.		2021-06-13 10:57:17 +02:00
