New release of libpfm for papi-7.0.1?

[William Cohen]

Hi,

I was taking a look at putting the new papi-7.0.1 into Fedora rawhide, https://bugzilla.redhat.com/show_bug.cgi?id=2177906 . Fedora build a separate version of libpfm rpms rather than using the libpfm source bundled with papi. PAPI-7.0.1 is dependent on the following patch in the libpfm git repo that are not in a released version of libpfm which updates the data struct to match newer kernel.

commit 8c606bc2f2d186c2797d9f013283c9150f594f93
Author: Masahiko, Yamada <yamada....@fujitsu.com>
Date: Tue Sep 20 14:04:31 2022 +0900

update perf_event.h to Linux 5.18

The perf_events interface for directly accessing PMU registers
from userspace for arm64 has been formally implemented in the
kernel v5.18.

Update perf_event.h header used to build perf_event based examples.

Signed-off-by: Masahiko Yamada <yamada....@fujitsu.com>

Would it be possible to have an updated version of libpfm releasedr? The alternative would be to build a version of libpfm with the patch in Fedora to allow papi-7.0.1 to build, but having a libpfm with all recent patches would be cleaner.

Thanks,

-Will

Hi Will,

I can make a new release but I am not sure I understand why it will solve your problem.

Thanks.

 

Thanks,

-Will

Hi,

I made a patched version of libpfm in Fedora rawhide for papi-7.0.1 to work around the lack of a release of libpfm with commit 8c606bc2f2d186c2797d9f013283c9150f594f93 (*). Having a release of libpfm was to make make it easier to describe the requireents for building papi-7.0.1 with an external libpfm library.

Thanks,

-Will

* libpfm with patch https://koji.fedoraproject.org/koji/buildinfo?buildID=2169815
papi-7.0.1 built with that libpfm, https://koji.fedoraproject.org/koji/buildinfo?buildID=2170338
