Public bug reported:
perf can be built against libopencsd which enables decoding of coresight (arm)
trace data (on any architecture). libopencsd has been in Ubuntu since focal,
but the kernel has this feature off unless enabled (setting CORESIGHT=1 during
the perf build, and having libopencsd-dev present).
I'll knock up a patch and send it in if no-one beats me to it.
