Summary

Add system emulation of HP PA-RISC.

Owner

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:

Ongoing work is documented here:
