QEMU support status regarding hppa/parisc
Starting with QEMU version 2.12 (April 2018), qemu fully supports hppa user emulation (hppa-linux-user) and hppa system emulation (qemu-system-hppa). All necessary changes have been merged into the upstream qemu git tree.
PA-RISC machines need a firmware ("PDC" = Processor Dependend Code). Qemu includes a precompiled PDC firmware for hppa (pc-bios/hppa-firmware.img), which is based on a fork of SeaBIOS .
The QEMU eumulation is able to run Linux and HP-UX. Improved HP-UX support is still being worked on.
QEMU on parisc has been made available by:
- Richard Henderson: QEMU CPU emulation, QEMU hardware divers
- Helge Deller: QEMU hardware drivers, SeaBIOS PDC firmware
- Sven Schnelle: Lots of fixes all over QEMU and SeaBIOS (SCSI, CPU emulation fixes, SeaBIOS PDC firmware)
Ready-to-run QEMU image for parisc
Download Debian hard disc image:
wget http://backup.parisc-linux.org/qemu/debian-10-hdd-img.tar.bz2
Unzip image:
tar xvfj debian-10-hdd-img.tar.bz2
Run qemu:
./hppa-softmmu/qemu-system-hppa -drive file=debian-10-hdd.img -nographic -serial mon:stdio -accel tcg,thread=multi -smp cpus=4
Log in as root, root password is "rootme"
How to build QEMU from source
Check out the qemu git tree
Run configure, e.g.
- (for system emulation) ./configure --target-list=hppa-softmmu --enable-numa
- (for user emulation) ./configure --target-list=hppa-linux-user --disable-stack-protector --prefix=/home/qemu-hppa/chroot-unstable --interp-prefix=/home/qemu-hppa/chroot-unstable --static
Run "make"
How to run QEMU with Debian-10 installer image
- Create a virtual hard disc once:
qemu-img create -f qcow2 hdd.img 50G
- download a Linux install image, e.g.
- Start emulator with the installer image once:
./hppa-softmmu/qemu-system-hppa -drive file=hdd.img -drive file=debian-10.0-hppa-NETINST-1.iso,media=cdrom -boot order=d -nographic -serial mon:stdio
- Choose typical installation options, the defaults are OK.
- Either skip the step "Configure the Package manager", or configure the mirror as with hostname "ftp.ports.debian.org", and directory "/debian-ports"
- Shut down virtual machine after installation
- Start emulator with installed operating system any time:
./hppa-softmmu/qemu-system-hppa -drive file=hdd.img -nographic -serial mon:stdio -accel tcg,thread=multi -smp cpus=2
- Edit the sources.list (/etc/apt/sources.list) file:
deb http://ftp.ports.debian.org/debian-ports unstable main deb [arch=all] http://ftp.debian.org/debian unstable main deb-src http://ftp.debian.org/debian unstable main
Some QEMU notes
Prefer the e1000 driver over the rtl8129 card. The latter gives irq issues with Dino emulation.
Possible qemu options:
- -accel tcg,thread=multi - always use this to enable parallel tcg (otherwise all guest CPUs run on one host CPU)
- -smp cpus=4 - define number of CPUs in the guest (maximum CPUs: 32)
- -boot menu=on - Firmware: enable interactive mode (boot prompt)
- -boot order=c - Firmware: Boot from hard disc
- -boot order=d - Firmware: Boot from CD/DVD
- -serial mon:stdio use serial console
- -nographic - no graphics device
- -device VGA - provide PCI VGA graphic card
