Arm's internal test infrastructure has started seeing failures for the
pmu-chain-promption test in kvm-unit-tests on TX2 when running mainline
and kvm-unit-tests commit 2480430a36102f8ea276b3bfb1d64d5dacc23b8f
("configure: Show the option in case it is not known"). The log I'm
seeing from the test runner is:
TESTNAME=pmu-chain-promotion TIMEOUT=90s ACCEL= ./arm/run arm/pmu.flat -smp 1 -append 'pmu-chain-promotion'
FAIL pmu-chain-promotion (7 tests, 2 unexpected failures)
Unfortunately I don't have direct access to a TX2 so can't readily
alter the test run other than replacing the kernel. I believe the
specific failures were:
FAIL: pmu: pmu-chain-promotion: 32-bit overflows: CHAIN counter enabled: CHAIN counter was incremented and overflow
FAIL: pmu: pmu-chain-promotion: 32-bit overflows: CHAIN counter enabled: 32b->64b CHAIN counter was incremented and overflow
A bisect (log below) identified 7af9da8ce8f9a16221e ("thunderbolt: Add
quirk to disable CLx") as the breaking commit which doesn't seem
entirely credible unless there's some image size thing going on, the
issue manifests with v6.3-rc3 and not with v6.3-rc1.

Yes please let me know if it fixes your issue. I also tried bisection
but it did not lead to anything.

FWIW, that worked for me; I replied there with a Tested-by (and test results).
