ENGR00225912 ARM: etm: Add trace buffer support
start trace:
echo 1 > echo 1 >/sys/devices/etm.0/trace_running
Notes: The other cores ptm also enabled by above command.
dump trace buffer:
echo v >/proc/sysrq-trigger
Decode trace buffer:
/unit_test/etm --pft-1.1 --sourceid-match 0 < /dev/tracebuf
Notes: this version need connect JTAG to make etm work.
