Title:
coresight debug is not enabled in perf
Status in linux package in Ubuntu:
Incomplete
Bug description:
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.
