Sysprof 1.1.2 is now available. This is a development release leading
up to a stable 1.2.0 release.

Sysprof is a sampling system-wide CPU profiler for Linux. This
version is based on the perf counter interface in 2.6.31 kernels and
will not work with earlier kernels.

Major new features since version 1.0:

* Commandline interface, [Lorenzo Colitti]

* Stacktraces for both kernel and userspace

* More accurate accounting when processes rapidly appear or
disappear.

* Profiles can be cutted and pasted

* Improved performance


Version 1.1.2 is a development release. Please report bugs to
sandmann(a)daimi.au.dk.

Thanks,
Soren

Btw, what is the plan for the sysprof ftrace plugin? In general we move
away from ftrace plugins towards trace events and perf, and if I
remember correctly ftrace file format changes caused enough pain for
sysprof that it kept shipping it's old hacky kernel module.

Is it time to deprectate the sysprof ftrace plugin?

Will either of you prepare an officially deprecation statement?
