Title:
support thunderx2 vendor pmu events
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Artful:
Fix Committed
Status in linux source package in Bionic:
Fix Released
Bug description:
[Impact]
ThunderX2 vendor pmu events are not supported.
[Test Case]
Successful output:
$ sudo perf list | grep thunderx2
thunderx2 imp def:
$
[Regression Risk]
The code changes are restricted to the perf utility, so there's negligible
risk to the kernel itself. All patches are clean cherry-picks except 1 where a
hunk is dropped that was updating an API in code that didn't exist yet.
I've tested on Cavium Sabre (a thunderx2 system), and smoke tested
perf commands for regression on x86 (Dell XPS13 9350).
