We could do with validating that the CRTC is within the fb->obj, otherwise we run foul of hanging the hardware. (Since this is a pre-existing condition it doesn't mar these patches.) So the only question is whether we indicate to userspace that the kernel is fixed? Or just kill the w/a in userspace and for reasons of sanity strongly encourage everyone who hits this to upgrade? Since this is no stable material, having keeping the w/a seems to make sense... -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
