Introduction to Linux on PA-RISC
PA-RISC Linux porting project
Linux distributions for PA-RISC machines
| Oregon State University Open Source Lab
| Roberto C. Sánchez sponsored a HP rp3410 server with one 800 MHz PA8900 CPU. (May 2017)|

|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.|
|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.|
|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.|
|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!
