Detailed Summary

System emulation of HP's PA-RISC platform. Both 32-bit (PA1.1) and 64-bit (PA2.0). Emulated systems would likely include one of the 'Snakes' (e.g. the 715/100), the C180/C240/similar, and C3000 or similar.

Status

• Only PA1.1 (32-bit) supported yet.
• Instruction decoding, branching and most instructions are emulated.
• User mode emulation has been added (since QEMU 2.9).
• System mode emulation has been added (since QEMU 4.0).
• A fork of SeaBIOS exists, which emulates a B160L workstation.
• Booting Linux and HP-UX works.
• Generic Tulip PCI NIC support for qemu was added.
• Graphics card emulation (artist) added.

TODO

• More testing
• Add more devices for system emulation, e.g.
  • LASI
  • Elroy PCI bridge
• Enhance SeaBIOS to emulate 64-bit firmwares
• Add emulation of a C3000 workstation

Code

The qemu code has been pushed into the qemu git repository.

A fork of SeaBIOS to run on PA-RISC is in the external git repository at:
