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
