Hi,
I just built a kernel from the 6.2.2 fc37 src.rpm. It built fine, but
at the end there was a missing file warning for cpufreq.h. I build the
header files when building the kernel, so I would think that would be
included in them.
The error:
+ exit 0
File not found:
/home/stan/rpmbuild/BUILDROOT/kernel-6.2.2-300.20230305.fc37.x86_64/usr/include/cpufreq.h
absolute symlink: /lib/modules/6.2.2-300.20230305.fc37.x86_64/build ->
/usr/src/kernels/6.2.2-300.20230305.fc37.x86_64
The second one is always there, a warning about a workaround as I
understand it.
I find this in the SPEC file:
%if %{with_headers}
%files headers
/usr/include/*
%exclude %{_includedir}/cpufreq.h
%endif
When I search the BUILD tree I find:
./linux-6.2.2-300.20230305.fc37.x86_64/include/linux/cpufreq.h
./linux-6.2.2-300.20230305.fc37.x86_64/include/linux/sched/cpufreq.h
It seems that these are there but the above stanza in the SPEC file is
excluding them. Is there a reason? Is it harmless?
There is another cpufreq.h present,
./linux-6.2.2-300.20230305.fc37.x86_64/tools/power/cpupower/lib/cpufreq.h
but I am not building tools, so it is probably being ignored. Do I
have to build tools to pick this up?
More detail on this is in
https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1903 but
for Fedora, we ship cpufreq.h in kernel-tools, not kernel-headers.
