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
