Programming Guides for Linux on Power

This project contains documentation helpful to application developers for Linux on OpenPOWER systems. The following documents are contained:

  • Linux on Power Porting Guide: Vector Intrinsics -- A guide to porting x86 vector intrinsics to the OpenPOWER processor. The online version of the document can be found in the OpenPOWER Foundation Document library at TBD.

  • Intrinsic Function Programming Reference -- A document detailing the various vector intrinsics on the OpenPOWER processor. This document is just beginning to be created.

To build this project, one must ensure that the Docs-Master project has also been cloned at the same directory level as the Programming-Guides project. This can be accomplished with the following steps:

  1. Clone the master documentation project (Docs-Master) using the following command:
$ git clone
  1. Clone this project (Programming-Guides) using the following command:
$ git clone
  1. Build all the documents withing the project with these commands:
$ cd Programming-Guides
$ mvn clean generate-sources

The project which controls the look and feel of the document is the Docs-Maven-Plugin project, an OpenPOWER Foundation private project on GitHub. To obtain access to the Maven Plugin project, contact TSC Chair of the OpenPOWER Foundation [](mailto:// or
