RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description William Cohen 2016-03-24 14:36:39 UTC
Description of problem:  RHEL 7 currently has libpfm-4.4 with backported patches to support some additional processors.  libpfm-4.7  was released in February and adds support for a number of newer processor implementations (http://perfmon2.sourceforge.net/)

Expected results:  Include support for a number of additional processors with the libpfm rebase such as Intel Broadwell-DE and Intel Skylake.

Comment 1 William Cohen 2016-05-12 17:18:12 UTC
Rebased to libpfm-4.7.0

Comment 5 Michael Petlan 2016-09-21 12:37:09 UTC
Well, for now I think the coverage is reasonable, thus we may move this bug further I guess.

Tests ran on the following environments:

x86_64:    BDX, NHM, NHM-EP, NHM-EX, WST, WST-EP, WST-EX, AMD16, AMD21, KNL, BDW-EP, KBL-UY, SNB, IVB, IVB-EP, SNB-EP, HSW60, HSW69, BDW-U, Avoton

ppc64:     POWER7, POWER8_LPAR, POWER8_KVM, POWER7+
ppc64le:   POWER8_LPAR, POWER8_KVM

aarch64:   Cortex A57, Mustang X-Gene

Current version of libpfm does not seem to cause any troubles in the dependent software.

VERIFIED
