Introduction

This architecture is for 64-bit IBM POWER8 machines using little endian byte ordering.

This is the first major release of ppc64le by the AltArch Special Interest Group. This release is based on the Source Code from CentOS 7 (1511) x86_64 Architecture and includes all current updates from the main CentOS 7 tree. It is derived from Red Hat Enterprise Linux 7.2.

Known Issues

Missing Ada compiler

Building gcc-gnat, libgnat requires gcc-gnat >= 3.1, libgnat >= 3.1. There isn't a Fedora ppc64le Ada compiler to bootstrap the CentOS ppc64le Ada compiler. I am still investigating a x86_64->ppc64le cross toolchain to bootstrap Ada. For now, gcc.spec has been modified with %global build_ada 0.

Installation

Installation is performed via the install ISOs and is the same as described in the standard CentOS 7 installer articles.

Basically, boot one of the install ISOs and use the anaconda installer OR use a custom kickstart file.

Install ISOs are available here:

Getting involved

The ppc64le effort is being done as a community SIG project. Everyone is welcome to participate. We still need community help to maintain documentation and also fix issues that may arise in this architecture.

We encourage vendors to come and join this effort, especially OpenPOWER community members.

The wider CentOS Ecosystem is also welcome to engage with us, both at the project and code level. If you are working with a project that interfaces, manages or develops on top of CentOS, especially in the virtualization, cloud, container and infrastructure management areas - we would love to have you guys get involved.
