.LP
|
|
Performance counters for Linux are are a new kernel\-based subsystem
|
|
that provide a framework for all things performance analysis. It
|

|
|
and software features (software counters, tracepoints) as well.

Each version of the perf tools may depend on new kernel features, so
|
|
you must install a different version for each kernel version. The
|
|
\fBperf\fR command will automatically run the correct version for the
|
|
running kernel version.
