In order to enable Ubuntu to read the PMU properly on a POWER9 system, the following commits are required: a2391b35f1 powerpc/perf: use is_kernel_addr macro in perf_get_misc_flags() 78a16d9fc1 powerpc/perf: Avoid FAB_*_MATCH checks for power9 8d911904f3 powerpc/perf: Add restrictions to PMC5 in power9 DD1 356d8ce3d0 powerpc/perf: Use Instruction Counter value 8a088542c8 powerpc/perf: Use PM_INST_DISP for generic instructions sample a114aca57a powerpc/perf: Add alternative event table and function for power9 ac19670eb1 powerpc/perf: Add PM_INST_DISP event to Power9 event list efe881afdd powerpc/perf: Factor out event_alternative function We need to have these patches in the kernel if we want to use perf, for example. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Taco Screen team (taco-screen-team) Status: New ** Tags: architecture-ppc64le bugnameltc-151974 severity-high targetmilestone-inin1704 ** Tags added: architecture-ppc64le bugnameltc-151974 severity-high targetmilestone-inin1704 ** Changed in: ubuntu Assignee: (unassigned) => Taco Screen team (taco-screen-team) ** Package changed: ubuntu => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1667413 Title: POWER9: Improve PMU capabilites Status in linux package in Ubuntu: New Bug description: == Comment: #0 - Breno Henrique Leitao <bren...@br.ibm.com> - 2017-02-23 11:27:50 == Hi Canonical, In order to enable Ubuntu to read the PMU properly on a POWER9 system, the following commits are required: a2391b35f1 powerpc/perf: use is_kernel_addr macro in perf_get_misc_flags() 78a16d9fc1 powerpc/perf: Avoid FAB_*_MATCH checks for power9 8d911904f3 powerpc/perf: Add restrictions to PMC5 in power9 DD1 356d8ce3d0 powerpc/perf: Use Instruction Counter value 8a088542c8 powerpc/perf: Use PM_INST_DISP for generic instructions sample a114aca57a powerpc/perf: Add alternative event table and function for power9 ac19670eb1 powerpc/perf: Add PM_INST_DISP event to Power9 event list efe881afdd powerpc/perf: Factor out event_alternative function We need to have these patches in the kernel if we want to use perf, for example.
