I did declare the configs in the config file but I missed it in my patch
as stated earlier. IIUC, that would not cause this error though.

Maybe I should exit with the skip code if no CGROUP_MISC (no more
CGROUP_SGX_EPC) is configured?

OK, so I wanted to do a distro kernel test here, and used the default
OpenSUSE kernel config. I need to check if it has CGROUP_MISC set.

tools/testing/selftests$ find . -name README
./futex/README
./tc-testing/README

./zram/README
./livepatch/README
./resctrl/README

So is there a README because of override timeout parameter? Maybe it
should be just set to a high enough value?

BR, Jarkko



 From the docs, I think we are supposed to use override.
See: https://docs.kernel.org/dev-tools/kselftest.html#timeout-for-selftests

Thanks

Maybe you are suggesting we add settings file? I can do that.
README also explains what the tests do though. Do you still think they should not exist?
I was mostly following resctrl as example.

Thanks
Haitao


With the settings I shortened the README quite bit. Now I also lean towards removing it. Let me know your preference. You can check the latest at my branch for reference:
