From: Jeff McGee <jeff.mcgee@xxxxxxxxx>
New test core_getparams consists of 2 subtests, each one testing
the ability of userspace to query the correct value of a GT config
attribute: subslice total or EU total. drm/i915 implementation of
these queries is required for Cherryview and Gen9+ devices (non-
simulated).
For: VIZ-4636
