Hi,
This patchset (sent as RFC) adds an emulation of the IBM RS/6000 43p, also
known as 7248.
It contains the strict minimum to be able to boot a PReP boot partition on a
IDE hard disk.
It has been tested with the official firmware, named P93H1904.IMG.
However, Andreas has already some preliminary patches for OpenBIOS to support
PReP machines.
Command line may look like
qemu-system-ppc -M 43p -bios P93H1904.IMG -readconfig ibm_43p.cfg
-device ide-hd,drive=hd0 -drive if=none,id=hd0,cache=writeback,file="hda.qcow2"
Known bugs/missing parts:
- incomplete MPC105 (PCI host bridge) emulation (IRQs, memory controller)
- no video card (should be a S3)
- can't boot from IDE cdroms (overlapping commands not supported by QEMU IDE
emulation)
- can't boot from floppies (READ commands are issued, but it seems completion
is ignored)
- can't boot from network
- hack added in the m48t59 device (anyone knowing the m48t59 emulation to
comment?)
- QEMU can't change endianness at runtime
Patchet also doesn't pass checkpatch.pl yet.
Please comment.
Regards,
Hervé
