Hi Arnaldo and Jiri,
Glad to see the progress we made today.
Before you trying libbaleltrace, please consider these two patches,
which allows print BPF output data directly through 'perf script'.
I think it would be useful for people don't have libbabeltrace ready.
With these two patch they can write scripts by their own:
# ./perf script
usleep 4882 21384.532523: evt:
ffffffff810e97d1 sys_nanosleep ([kernel.kallsyms])
BPF output: 0000: 52 61 69 73 65 20 61 20 Raise a
0008: 42 50 46 20 65 76 65 6e BPF even
0010: 74 21 00 00 t!..
BPF string: "Raise a BPF event!"
usleep 4882 21384.632606: evt:
ffffffff8105c609 kretprobe_trampoline_holder ([kernel.kallsyms
BPF output: 0000: 52 61 69 73 65 20 61 20 Raise a
0008: 42 50 46 20 65 76 65 6e BPF even
0010: 74 21 00 00 t!..
BPF string: "Raise a BPF event!"
Thank you.
