Hello

There is hardly any documentation and I do not know what I am doing wrong. ptfuzzer.py error: ... afl-fuzz 2.52b by lcamtuf@google.com raw_bin: .testbin.text min_addr: 93824991235680 max_addr: 93824991265601 entry_point: 93824992244510 init pt fuzzer. start to disassmble binary... build_cofi_map, total number of cofi instructions: 1050 cofi map complete percentage: 100% [+] You have 12 CPU cores and 1 runnable tasks (utilization: 8%).

My cpu supports Intel PT and tested using perf record -e intel_pt// /bin/ls

Version: Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz

Please help

Thank you, figure out yesterday and fixed it with this. How is possible to run parallel fuzzing? I can't run master and slaves using this fork.

@agarciagonzalez currently PTfuzzer dose not support parrallel fuzzing because of the filter mechanism (several MSR registers)
