Hi Nitin, [...] > Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/13650 [...]
> ENGINE_READ_FW(engine, RING_START)); > + /* > + * Sometimes engine head failed to set to zero even after > writing into it. > + * Use 20ms delay to let engine resumes from correct RING_HEAD. > + * Experimented different values and determined that 20ms works > best > + * based on testing. > + */ > + mdelay(20); Since we do not propagate the errors returned from `stop_ring()` function and the linked issue is not a failure, because the subtest succeeds, I wonder if we could lower the severity of this log to a warning. Regardless of whether you consider my suggestion or not, the patch looks good to me: Reviewed-by: Krzysztof Karas <krzysztof.ka...@intel.com> Best Regards, Krzysztof
