[igt-dev] [PATCH i-g-t 2/2] tests/xe_query: Query and sanity-check GT ip versions

[Matt Roper]

Update the query test to include the GT's IP version in the output and
to also perform some simple sanity checks on the version received.  We
don't want to try to match any specific version numbers (since we expect
new versions to show up in the future), but we do know that the uapi
should never return version numbers older than 12.70 for the primary GT
or 13.00 for the media GT since those were the first IP versions to
include GMD_ID support.  We also know that MTL/ARL are the only pre-Xe2
platforms to support GMD_ID, so if we're not running on MTL/ARL, the
version numbers must always be 20.00 or greater.
