Updated console patch
by Blue Swirl
I implemented missing methods etc. to make OpenBIOS obey Qemu's -nographic
flag. This means that Linux can automatically select the correct console
device, screen or serial.

Quilt-ified patches
by Blue Swirl
Hi,
I finally learnt how to use Quilt to manage patches. The previous patch is
now in several parts, which should be easier to handle.
The order of applying should be:
autocrosscflags.diff
vga.diff
cleanup.diff
console-nographic.diff
64_bit_fixes.diff

Very cool!
PearPC pretty much stayed unsupported since I never got the ADB portion
of the code to work properly. PearPC uses "PC style serial ports" as
well..

Re: [OpenBIOS] QEMU PPC support for OpenBIOS
by Greg Watson
Take a look at the briq code. I hand crafted the device tree, but I
was able to get to the point of booting Linux from an IDE drive.
Things failed at that point because I didn't have the interrupts set
up correctly. There should not be any serious problems getting PPC to
work.

QEMU PPC support for OpenBIOS
by Wessel, Jason
I started porting the OpenBIOS to the PPC qemu, and I was curious of the
state of the PearPC portion of the OpenBIOS. I thought I check and ask
if there is another branch or if someone was already working in this
area or had it working.
I would be happy to collaborate and share some patches.
Nothing really works at this point, but it is further along then having
nothing:

/pci/via-cuda/adb has no read method.
Output device screen not found.

I get that on the serial port for PPC qemu, and now I have to work
backwards to fix it up correctly. Serial input doesn't work quite right
and that will probably be the first hurdle.
Any pointers to active or recent projects in this area would be
appreciated.
Cheers,
Jason.

Solaris
by Jason Hooper
I've noticed two things over the weekend.
1) sun-parts seems to be off by 1 (it is counting the vtoc as the first partition, which it should not , AFAIK). I will submit a patch when I get a chance.
2) I am getting a bit further with the Solaris boot if I enable all the QEMU debugging (-d in_asm,exec,cpu,op,int,out_asm).
SunOS starts and then I get message:
Cannot load drivers for sd(0,2,0)@0,0:b (or :a with the sun-parts fix)
Can't load the root filesystem
I thinks QEMU emulates SCSI 3 and Solaris wants SCSI 1 or 2. Can we load drivers or emulate a supported environment?
There seems to be some sort of timing issue with the startup. If I disable all QEMU debugging, it starts about1 in 20 times. If I enable it all, about 1 in 2 times.
Hope this helps.
