| 2014-07-16 | perf script: Add callchain to generic and tracepoint events | Joseph Schuchart | 1 | -1/+1 | |
| This provides valuable information for tracing performance problems. Since this change alters the interface for the python scripts, also adjust the script generation and the provided scripts.

| 2014-06-25 | perf scripts: Fallback to syscalls:* when raw_syscalls:* is not available | Daniel Bristot de Oliveira | 1 | -0/+5 | |
| 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.

| 2010-12-25 | perf script: Finish the rename from trace to script | Arnaldo Carvalho de Melo | 1 | -1/+1 | |
| The scripts have calls to 'perf trace' that need to be converted to 'perf script', do it. This problem was introduced in 133dc4c.

| 2010-02-25 | perf/scripts: Add syscall tracing scripts | Tom Zanussi | 1 | -0/+58 | |
| Adds a set of scripts that aggregate system call totals and system call errors. Most are Python scripts that also test basic functionality of the new Python engine, but there's also one Perl script added for comparison and for reference in some new Documentation contained in a later patch.
