[Perfctr-devel] New release of libpfm for papi-7.0.1?

[William C. <wc...@re...>]

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.

    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.

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
