Hi,
I am still trying to boot OS/2 PPC edition with Qemu. Non-contiguos
IO map & no support for Little-endian have been solved now thanks to J.
Mayer who sent me patches to work these out. Now bootloader gives me
following message:
IBM Microkernel bootloader press enter for manual boot(enter)
and I have following boot options to choose from:
cdrom
hd
if I try to use either one of these Qemu gives me
outl: port= 0x0cf8 data=0x80006000
inl: port= 0x0cfc
(Bootloader continues with)
Invalid PCI configuration
Device initializion failed
Any ideas why is this?
And I have also another note I have made:
Boot loader catches a bug if I try to use any other machine model(in
bootinfos.c) than IBM PPS Model 6050.
If I give I 6070 Qemu catches a bug. I have done some researching and
6070 & all other models accepted by this bootloader have "thing" called
PCI_ACCESS_DEVICE. 6050 does not have this might this be the reason why
6050 is the only machine of these that boots? And if someone knows what
is this thing pls tell me too :)

There are two problems here:
first, the PREP PCI controller does not map its legacy ISA IO ports.
This is a bug.
But fixing this point is not sufficient to make the loader happy:
it tries to access the PCI device 0x60 (96) which does not exists. Then,
I think the lack of devices description in Open Hack'Ware residual data
can be a good suspect for this. Or it can be that real PREP machine
always have the IDE (or SCSI !) controller mapped as PCI device 0x60,
but I'm very suspicious about this.

There still have two possibilities. The first would be that ther's a bug
in the info given by Open Hack'Ware then OS/2 loader gets confused then
crashes. The second is still the lack of hardware description in Open
Hack'Ware residual data.
You may try to hardcode a simple hardware description (just PCI with
IDE, for example) there...

Ok,
What I have made now:
1. Changed vendor id of PREP Pci bridge from 1011 to 1014 (ibm)
2. Tried booting and noticed that Bootloader did:
pci_config_read: PCI Bridge address:10 value: 0xffffffff
3. Found out that address 10 should have base adress in it.
4. modified this with:
d->config[0x10] = 0x08
d->config[0x10] = 0x00
d->config[0x10] = 0x00
d->config[0x10] = 0xF0
to be 0xF0000008
Is this ok?(I just figured it out somehow)
Now bootloader gives me:
dma:command 0x24 not supported
dma:command 0x25 not supported
Just figuring out what these commands are....

Turned on #debug DMA and here is the whole deal:
command: 0x24 not supported
write_cont: nport 0x0009, ichan=0
read_cont: nport 0x000c, port=0x0c, valu=0000
command:0x25 not supported
write_cont: nport 0x0009, ichan=0
read_cont: nport 0x000c, port=0x0c, valu=0000
command:0x26 not supported
unknown device....
What is it trying to do and what goes wrong?

Could this LXR refernece be helpful?
