Usage: sudo perf record -e intel_pt//u --filter='filter 0x400000 / 0x1000 @./a.out' ./a.out 123 a.out is my program (for loop, call using function pointer and use of longjump) and 123 is the argument. Output: [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 1.171 MB perf.data ] Output contains mostly MTC packets and no TNT or TIP packets. I am on the latest mainline version of kernel (b67be92) and perf version perf version 4.8.gb67be9. What could be the problem? I am using it wrong? Thanks
