'perf record' and 'perf report --dump-raw-trace' supported in this
release.

Example usage:

 # perf record -e arm_spe/ts_enable=1,pa_enable=1/ dd if=/dev/zero of=/dev/null count=10000
 # perf report --dump-raw-trace

Note that the perf.data file is portable, so the report can be run on
another architecture host if necessary.

Output will contain raw SPE data and its textual representation, such
as:

0x5c8 [0x30]: PERF_RECORD_AUXTRACE size: 0x200000  offset: 0  ref: 0x1891ad0e  idx: 1  tid: 2227  cpu: 1
