I came across a few generic non-Arm issues when reviewing Anshuman's new support for branch record buffers on Arm [1].
The first one is a fix to an error message which is misleading if the feature is unavailable and the remaining ones make the branch type field visible in perf report and perf script so that it can be debugged or used by other tools.
Applies to perf/core (56dce86819)
Thanks James
