However, as you haven't fixed the ordering issue that requires rpm_get before struct_mutex, this is broken. When we have rpm fixed, you don't need this patch as we can take the wakeref around the GSM access itself. We still want the prolonged rpm wakeref for the GPU activity, ofc. -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
