(intel_fbdev_fini() is already module unload, right? Do you mean just move the async handling into i915_driver_unload() so that we have a single spot for all future potential users of the async framework?) And optimising module unload to avoid one potential grace period when we already have a bunch of grace period waits seems overkill. The alternative to using async_synchronize_full() would be to use an async-domain. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
