These patches allow the trace to be recorded with perf, but what do you
use to actually get something useful out of the resulting perf.data?
AFAICS it can't be processed by perf script or the other perf tools.
# echo 1 > /sys/bus/coresight/devices/54162000.etb/enable_sink
# perf record -e cs_etm// true
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.032 MB perf.data ]
# perf script
0x188 [0x80]: failed to process type: 70
