The CFL issue is different from the original reported, but since this bug has been used for that since comment 14 and no other bug about it is open, I'll reuse this one. For future references, please post only if it's the same issue. Thank you.

First of all. Sorry about spam.
This is mass update for our bugs.

Sorry if you feel this annoying but with this trying to understand if bug still valid or not.
If bug investigation still in progress, please ignore this and I apologize!

If you think this is not anymore valid, please comment to the bug that can be closed.
If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug.

The IGT perf tests rely on gt information from devinfo to determine the test_config uuid that needs to be passed to the driver to enable the tests.

intel_gt function in IGT needs to change to return the correct encoding.

Fix from Lionel - https://patchwork.freedesktop.org/patch/222867/

Mashine: cfl
Repro rate: 100%
Test Coverage Impact: IGT perf tests will fail on CFL
User Impact: None. This issue affects IGT primarily. Functionality of perf or the i915 driver is not affected.

could you please verify with latest sources

In the latest sources, the offending code has moved to lib/i915/perf.c and does not cause this issue anymore. This bug can be closed.
