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. |
Make a new build directory. If this build directory is build root and the directory where this file is found is called src root, do the following to install:
cd <build root>
cmake <src root> -DCMAKE_INSTALL_PREFIX:PATH=<prefix>
make install DESTDIR=<destdir>
The installation directory will be //bin for binaries, and //share/man for man pages.
If -DCMAKE_INSTALL_PREFIX:PATH is not given, then the default value is: /usr/local
The default value for DESTDIR is the empty string.

When sending single patches, please using something like:
git send-email -1 --to [email protected] --subject-prefix=rt-tools][PATCH --compose
or, if this is re-send of patch having a version number 2:
git send-email -1 --to [email protected] --subject-prefix=rt-tools][PATCH v2 --compose
For multiple patches, "-1" is increased with how many patches from the top to be sent.
