[Qemu-devel] [RFC 00/23] PReP 40P emulation

[Andreas Färber]

Hi,

Based mostly on earlier work by Hervé Poussineau, this RFC series adds
emulation of a real '40p' IBM PReP machine as an addition to the existing
'prep' machine. It does some general cleanups and qdev'ification
that will benefit further PReP machines, such as the BeBox.

This series supersedes my preparatory "ISA reconfigurability" series,
by adding the i82378 PCI-ISA bridge on which it is to be used. The qdev and
ISA device patches up to pc87312 should allow for cherry-picking.

The state of -M prep (on Darwin/ppc64 and OSol/amd64) is that my
2.4.36.1 Linux kernel hardly gets to the root prompt
("INIT: Id "n" respawning too fast: disabled for 5 minutes"),
both before and after.

Firmware for -M 40p can be downloaded here:
ftp://ftp.boulder.ibm.com/rs6000/firmware/7020-40p/P12H0456.IMG

With some additional patches on top of this series (memory-forced
I/O, a PCI BAR issue and a parallel ioport conflict) after about
one and a half minutes it gets to the graphical boot screen with
keyboard icon, after about seven and a half minutes to the floppy icon
and after a really looong time gets to a third, memory(?) icon.

TODOs:
* improve ISA ioport vs. IORange handling and naming
* fix a few -M prep System I/O ports broken by qdev'ification
* possibly make -M prep use i82378, too (broke Linux boot)
* IBM8514/A cleanup, RAMDAC support for colors
* 7020 had max. 6x 32 MB = 192 MB RAM

Regards,
Andreas
