Looks good to me. The series is:
Reviewed-by: Alex Deucher <alexander.deucher@xxxxxxx>
Thank you Alex for review and the help in finalizing the series
and to Harry who initially encouraged me and provided the feedbacks to previous v2 series

amdgpu does not currently implement GPU reset support for SI.
Alex
If you have in the plans to add support and prevent those crashes,
the user would be glad to be available for glxgears and piglit testing on Firepro W5130M
Please let me know
