You are trading an obvious error for a subtle one; if userspace got its batch wrong and doesn't die, the output will likely be wrong instead. mesa/src/intel/tools/intel_sanitize_gpu for how userspace could do this detection itself. You can intercept the execbuf, place a canary after the batch and report if the canary gets written. -Chris _______________________________________________ Intel-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/intel-gfx
