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 <yam...@fu...> 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 <yam...@fu...> 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 |
