PA-RISC Linux porting project

The PA-RISC project provides a native port of Linux to the PA-RISC architecture.
Today PA-RISC Linux is stable and runs on most PA-RISC machines.
PA-RISC Linux Project History tells how the project got started. See the Hall of Fame for a list of folks who brought you the initial 0.9x and Debian 3.0 releases.

[edit] Linux distributions for PA-RISC machines

Linux runs on most physical PA-RISC machines.
You may even install PA-RISC Linux in a virtual machine with Qemu.
Check the PARISC FAQ and Hardware support if you have trouble installing Linux.

Debian Linux

Debian Linux

PA-RISC is a non-release architecture in the Debian Ports project.
Debian Linux for PA-RISC is usable and stable with more than 12,800 Debian packages available.
You can download the latest installation ISO here or here.
Gentoo Linux

Gentoo Linux

PA-RISC is a fully supported architecture of Gentoo Linux.
The Gentoo hppa team provides 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.

[edit] PA-RISC NEWS

May 2023 palo version 2.24 released.
STI text console support on 64-bit machines, e.g. this allows using all original HP graphics cards in text-mode on C8000 workstations.
Fix palo to speed up printing the IPL menu on C8000 workstations.
Apr 2023 Debian-12 (Bookworm) preparations, with more than 13,000 pre-built packages.
Progress on an upcoming Visualize-FX5 fbdev graphics driver.
Mar 2023 More than 12,900 pre-built Debian packages available.
Jan 2023 Availability of a new HP J6700 dual-core debian porterbox parisc.debian.net, sponsored by Cypress Technology Inc. This machines was upgraded to 8 GB RAM and 2 x 300GB discs with parts of the former "parisc" HP A500-44 server.
Dec 2022 Adrian Glaubitz built a new Debian 11 installation media.
Helge submitted many fixes for qemu , e.g. for getsockopt(), msync(), /proc/cpuinfo file, madvise(), strace, sendmsg() and published an initial port of libc for rust.
Dave fixed a closure to function pointer bug in python-libcffi and spent a large amount of time reviewing debian buildd logs, doing give backs, and reporting issues. Furthermore Dave ported libffi to hppa64-hpux which exposed some issues in the 32-bit linux and hpux ports, e.g. 1, 2 and 3.
Linux kernel v6.2 will include a patch which allows parisc to use the same MADV constants for madvise() like other platforms.
Nov 2022 Installed new buildd servers "paladin" (a qemu-user emulation running Debian-x86 in VirtualBox on Windows).
Oct 2022 After 22 years the power supply in our A500-44 server (which was sponsored by HP) finally broke. It had hosted the ftp site and the mailing lists and was replaced by a x86-VM. Installed new buildd servers "pad" (a qemu-user emulation running Debian-x86 in VirtualBox on Windows) and "atlas" (physical C8000 machine).
Sep 2022 Lots of enhancements to the qemu-user emulation. Many of the debian buildd servers run now on x86 hardware which use qemu-user to build packages.
Aug 2022 New palo version 2.22 released, with support for booting without palo- or /boot paritions.

QEMU version 7.1.0 with many PA-RISC related enhancements and fixes has been released.

Jun 2022 Sam James added seccomp support in unit files on HPPA to systemd v252 and worked on elfutils support for HPPA.
John David Anglin helped to fix a glibc bug about broken argv adjustments
Mark Cave-Ayland provided lots of internal cleanups to the hppa PS/2 keyboard and PS/2 mouse emulation in the upcoming QEMU v7.1 to bring the source code up to latest QEMU coding standards.
May 2022 Linux kernel v5.18 released, includes vDSO-, CPU hotplug- and improved cache flushing support.
QEMU v7.1: Fix X11 cursor emulation in HP-UX and allow emulated PS/2 keyboard input in firmware boot menu
QEMU v7.1: Fix serial port pass-through from host to guest
Apr 2022 CPU Hotplug support added to Kernel v5.18.
PALO v2.16 released. Prior versions didn't showed all available kernels when listing /boot directory at IPL menu.
Mar 2022 A new set of debian-hppa installation medias for debian unstable provided by Adrian Glaubitz.

16 years after the initial vDSO patch by Randolf Chung, Linux kernel v5.18 will now finally include vDSO support. In addition Kernel v5.18 includes multiple TLB/cache-flush fixes and improvements.

Feb 2022 Many Qemu patches were applied to improve HP-UX graphics and mouse, allows up to 16 vCPUs, TOC support and much more. See our Qemu page.
Jan 2022 Kernel v5.16 released, with as many parisc enhancements and patches than never before!
Dec 2021 Richard Henderson and Helge Deller fix a mis-translation of the stby assembly instruction in Qemu.

Multiple important kernel fixes by Dave Anglin.

Nov 2021 Sven fixes a long-standing endianess bug in midnight commander which hangs the console when using F10 to exit.

Kernel v5.16 will include TOC and KFENCE support.

Sep 2021 Starting with Linux kernel 5.15, you will need to specify "ARCH=parisc64" on the command line when bulding a 64-bit kernel.

Adrian announced that he built new installation medias for debian unstable, ISO images are available here.

Jul 2021 The power supply of our old A400 server ("parisc") broke and got replaced. Machine is now back up again.
Feb 2021 Various fixes (e.g. 12) for qemu v5.2 to further improve qemu-user emulation.

Switch to a faster page table locking mechanism with Linux kernel v5.12.

Jan 2021 PALO v2.15 released.

New parisc Debian build server "pasta", which runs in a qemu-user parisc chroot environment on a x86-64 virtual machine with 8 CPUs and 16GB RAM. Many thanks to the OSU Open Source Lab who sponsors this VM!
Additionally there is a new parisc Debian build server "paq". This qemu-user based build server runs on a Synology DS920+ in a x86-64 virtual machine with 3 Intel Celeron J4125 CPUs and 1.5GB RAM.

1998-2020 See PA-RISC_Linux_Project_History for older news.
