Coresight on jetson TX2 Linux kernel 4.9 limitations!

is perf supported ? I keep getting “failed to mmap with 12 (Cannot allocate memory)”
when i do
“./perf record -e cs_etm/@8030000.etf/ --per-thread uname”

is mem_parser is the only thing that can be done ? Please let me know what limitations Jetson TX2 decoding tracing files has for kernel 4.9.

mem_parser doesnt show me any traces for the program I ran after enabling tracing and getting the ETB trace Bin file and decode it with mem_parser.

Sorry for the late response, we will investigate this issue to do the update soon.

is perf supported on JTX2 board on kernel 4.9 ? if yes , can you share an example on how to achieve that
