perf script/python: Print array argument as string
With the Sebastian's change of handling num array argument (of raw syscall enter), the script still failed to work like this: $ perf record -e raw_syscalls:* sleep 1 $ perf script -g python $ perf script -s perf-script.py ... Traceback (most recent call last): File "perf-script.py", line 42, in raw_syscalls__sys_enter (id, args), TypeError: %u format: a number is required, not list Fatal Python error: problem in Python trace event handler Aborted (core dumped) This is because the generated script tries to print the array arg as unsigned integer (%u). Since the python seems to convert arguments to strings by default, just using %s solved the problem for me.
