Hello,
kernel test robot noticed "RIP:cpuidle_enter_state" on:
commit: 74e2dbe7be5037a5e5eed6bc1ad562747ac88566 ("perf tools: Add --pmu-filter option for filtering PMUs")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
[test failed on linux-next/master 2febe6e6ee6e34c7754eff3c4d81aa7b0dcb7979]
in testcase: perf-sanity-tests
version:
with following parameters:
perf_compiler: clang
group: group-00
config: x86_64-rhel-9.4-bpf
compiler: gcc-14
test machine: 20 threads 1 sockets (Commet Lake) with 16G memory
(please refer to attached dmesg/kmsg for entire log/backtrace)
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags

Hello，
This kernel warning (irq 26 nobody cared) appears to be unrelated to my
perf userspace patch. It comes from the tps6598x Type-C controller
driver, which is likely a hardware or driver issue on the test machine.
All perf test cases passed successfully.
Please consider this as pre-existing test environment noise.
