[PATCH i-g-t 0/2] Add tests for EU stall sampling

[Harish Chegondi <harish.chegondi@intel.com>]

The patches in this series add IGT tests for EU stall sampling, a
hardware feature first introduced in PVC and also supported in XE2 and
later architecture GPUs.

The Xe driver patch that adds support for EU stall sampling is under
review: https://patchwork.freedesktop.org/series/142880/

These IGT tests were used to test the above driver patch.
