Subject: ci/bare-metal: Set CPU and GPU governors to max, disable GPU runtime PM
X-Git-Tag: upstream/21.2.3~1918
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a8c11552096c4576b71ef8dba49c9a58c9d22c0c;p=platform%2Fupstream%2Fmesa.git

ci/bare-metal: Set CPU and GPU governors to max, disable GPU runtime PM

Give us a bit more predictable performance by making sure we always run
at full tilt.
