perf scripts: Fallback to syscalls:* when raw_syscalls:* is not available · 07100877

Daniel Bristot de Oliveira authored 10 years ago

Older kernels (e.g., RHEL6) do system call tracing via the
syscalls:sys_{enter,exit} tracepoints rather than using raw_syscalls:*.

Update perf python and perl scripts to fallback to syscalls:* when
raw_syscalls:* isn't available.
