I think we may end up doing the reset unconditionally in i915_driver_unload() because this argument holds for almost everything we setup. It's a bigger risk because of doing the gpu-reset on more machines, but module-unloading is a "developer feature"! The only issue is making sure that the reset is ordered appropriately. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
