This Wiki is meant to be an entry point for the PA-RISC Linux port. Its contents are mostly directed to developers, but people wanting to learn more about the PA-RISC Linux kernel and the PA-RISC architecture secrets might find useful data here.

Introduction to Linux on PA-RISC

The PA-RISC project provides a native port of Linux to the PA-RISC architecture. The port was merged into linux-2.6 and linux-3.x mainstream Linux kernel tree. PA-RISC Linux Project History tells how the project got started and the first steps. Contact the Mailing lists if you want to volunteer your time.

See the Hall of Fame for a list of folks who brought you the initial 0.9x and Debian 3.0 releases. That includes boot loader, kernel, documentation, user space programs, packaging, testing, debugging, and pulling everything together into an ISO.

Linux distributions with support for PA-RISC Linux

PA-RISC Linux is currently supported by various Linux distributions, whith Gentoo Linux and Debian being the ones which currently provide the best support for the PA-RISC architecture.

Gentoo Linux
PA-RISC is a fully supported architecture of Gentoo Linux.
Many thanks to the smart people of the Gentoo Linux HPPA Development team for providing Gentoo Linux installation ISOs available for download!
If you wish to install Gentoo Linux for PA-RISC, we suggest that your read the Handbook on how to install Gentoo Linux for PA-RISC.
Debian Ports Linux
The PA-RISC Linux development community is proud to have been officially part of the Debian 3.1 (sarge), 4.0 (etch) and 5.0 (lenny) releases.
As of Debian 6.0 (squeeze) PA-RISC Linux was sadly dropped in July 2011 as officially supported platform which is why the PA-RISC Linux development currently happens as Debian-unofficial architecture in the [Debian Ports] project. Our Wiki contains a description on Debian Ports Installation.

Before downloading any ISOs for Gentoo, Debian or any other Linux distribution, first check the PARISC FAQ and Hardware support for issues specific to your hardware.


  • Jan 2014 - Updated Debian unstable install instructions. More than 8000 newly built native Debian packages available.
  • Dec 2013 - 5 buildd servers for debian unstable online. Stable Debian kernel 3.12 available.
