Pre-conditions:
----------------
Prepare same kernel of setup with this patch applied:
https://patchwork.freedesktop.org/series/3045/

Steps:
------
1. Boot with kernel without the patch applied
2. Execute IGT pm_rpm tests: basic-pci-d3-state and basic-rte
3. Boot with kernel with patch applied (GuC is loaded)
4. execute same tests

Actual result:
--------------
2. Tests are Pass
4. Tests are Fail:
