Updated console patch
by Blue Swirl 18 Jun '06

18 Jun '06

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. _________________________________________________________________ Express yourself instantly with MSN Messenger!

Quilt-ified patches
by Blue Swirl 17 Jun '06

17 Jun '06

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 _________________________________________________________________ Express yourself instantly with MSN Messenger!

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 16 Jun '06

16 Jun '06

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 15 Jun '06

15 Jun '06

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: >> ============================================================= >> OpenBIOS 1.0RC1 [Jun 15 2006 16:42] >> current nvram: >> ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff >> ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff >> ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff >> ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff >> nvram error detected, zapping pram >> Initializing PCI devices... >> ide0: [io ports 0x1f0-0x1f7,0x3f6] >> drive0 [ATA disk]: QEMU HARDDISK >> drive1 [ATAPI floppy]: QEMU CD-ROM >> Initializing ADB driver >> Autobooting disabled - dropping into OpenFirmware No cdrom found Output device /pci/pci6666,6666 not found. /pci/via-cuda/adb has no read method.

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.

This patch adds automatic detection of cross-compiler CFLAGS. There is some problem with dictionary: Dumping final dictionary to 'obj-sparc64/bootstrap.dict' Compiling dictionary 1/2 Dictionary initialization finished. base is not defined. interactive? is not defined. (to) is not defined. linefeed is not defined. interpretion finished. 4 errors occured. dictionary not dumped to file. _________________________________________________________________ Don't just search.

Solaris
by Jason Hooper 12 Jun '06

12 Jun '06

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. Regards,
