This repository contains a collection of tools for achieving real-time performance in Linux. It is currently focused on CPU isolation using cgroups/cpuset.

For information about license, see LICENSE file.

The following tools are available:

Executable	Description
partrt	Partition the CPUs into two sets: One set for real-time applications and one set for the rest. The goal for this tool is to achive tickless execution on the real-time CPU set. See man page found in "doc" sub-directory for more information.
count_ticks	Counts number of ticks that occur when executing one or several shell commands. Uses ftrace for this.
bitcalc	Bit calculator, helper application for partrt script.
