OProfile is a system-wide profiler for Linux systems,
|
||||
capable of profiling all running code at low overhead.
|
||||
OProfile is released under the GNU GPL.
|
||||
|
||||
It consists of a kernel driver and a daemon for collecting
|
||||
sample data, and several post-profiling tools for turning
|
||||
data into information.
|
||||
|
||||
OProfile leverages the hardware performance counters of the
|
||||
CPU to enable profiling of a wide variety of interesting
|
||||
statistics, which can also be used for basic time-spent
|
||||
profiling. All code is profiled: hardware and software
|
||||
interrupt handlers, kernel modules, the kernel, shared
|
||||
libraries, and applications.

Subject: [PATCH] opcontrol: don't use kill -s
|

Busybox's implementation of "kill" doesn't understand the "-s SIG"
|

option. Use "-SIG" instead.
