Bug Description
Hello,
For Arm platforms it is possible to capture Coresight Trace information with Linux perf. A library libopencsd-dev is then used to decode the coresight trace information.
On Debian, we already have perf linking against libopencsd-dev, this was addressed by:
https:/
Could we please have a similar change applied to the Ubuntu perf executables?
To implement this change one would need to:
1) Add libopencsd-dev to the build-deps,
2) Add CORESIGHT=1 to the make flags for perf.
Note that it would be beneficial for all architectures to link against libopencsd-dev (not just arm64) as this would allow users to decode coresight trace information on their local machine.
Cheers,
