[Qemu-ppc] [PATCH 0/4] PPC IBM 40p PReP emulation

From: Hervé Poussineau
Subject: [Qemu-ppc] [PATCH 0/4] PPC IBM 40p PReP emulation
Date: Wed, 10 Jun 2015 23:18:51 +0200


This patchset adds the emulation of the IBM RS/6000 7020 (40p). The real 
machine is
able to run AIX (up to 4.3.3), Windows NT (up to 4.0 SP1), the beta of OS/2 
Solaris, Linux, NetBSD/PReP ...

I've tested current emulation with Open Firmware PReP and with official 
Patch 2 has been of a great help when using official firmware. However, if 
I can drop it.

Linux kernel runs.
Windows NT starts up to the point where it wants to change endianness.
Other OSes have not been tested.

To test, download firmware a http://tyom.de/qprepofw-serial-svn-3738.rom . 
Thanks Artyom!
Then, run:
qemu-system-ppc -M 40p -bios qprepofw-serial-svn-3738.rom -readconfig 
ibm_40p.cfg -serial stdio

Note that you can't natively boot from a hard disk using Open Firmware, as 40p 
storage is SCSI.
