Perf tool in Jetson NX

I had already downloaded public_source package and finish “make” successfully.
But in the public_source file path “kernel/kernel-4.9/tools/perf” I operate "./perf stat -e cache-misses " with my file it’s still not working( cache-miss, cycles, instructions, branches, branch-misses all not supported)…

Sorry that we don’t have experience with this tool. Maybe other users can share experience.

Does there any tools in Jetson NX also can measure cache status?
