Around 6-8 months ago, selftests used to build kernel headers from the source tree automatically and were using those to build all applications. But this behavior got changed where user need to build header manually first before building kselftest because auto header build was in-consistent in some cases.

So from several months people, who were unaware of this are building kselftests with installed kernel headers in their distro. This was creating failure for some newer tests for people. They didn't know that selftests are supposed to build with kernel headers from source instead from locally installed headers in distro. So a patch has been introduced which spits error if kernel headers aren't built already: https://lore.kernel.org/all/20230606071637.267103-12-jhubbard@nvidia.com

To fix things for your case, please build kernel headers by `make headers ...` and then build kselftests. The error is trying to say the same thing.

make[3]: Entering directory '/builds/linux/tools/testing/selftests/alsa'

-e error: missing kernel header files. Please run this and try again:

cd /builds/linux/tools/testing/selftests/../../..
make headers
