From 07100877ea8fd9b2feabb4dd78f3322892f6bd77 Mon Sep 17 00:00:00 2001 From: Daniel Bristot de Oliveira Date: Wed, 11 Jun 2014 16:09:08 -0300 Subject: perf scripts: Fallback to syscalls:* when raw_syscalls:* is not available 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. Signed-off-by: Daniel Bristot de Oliveira Cc: Ingo Molnar Cc: Luis Claudio R.
