Subject: [PATCH v1 0/2] perf test: Output sub testing result in cs-etm

The "perf test" can be integrated into testing framework, e.g. Linux
kernel functional testing (LKFT) [1].  We are not satisfied with only
outputting the summarized result for Arm CoreSight testing but lacking
more detailed result for sub testing.

This patch set is to output sub testing result in cs-etm.  Thus the
testing framework can extract the detailed info and generates reports
for which sub cases causes failure.

This patch set is cleanly applied on perf/core branch with:

  commit 6db59d357e8e ("perf arm64/s390: Fix printf conversion specifier for IP addresses")

After applied the patches, which is tested on Arm Juno-r2 board with
option '-v', the output result is shown in below; the introduced sub
testing result has the format like:

  "CoreSight path testing (CPU0 -> tmc_etf0): PASS".
