qemu-system-ppc: cdrom:0, \ppc\chrp\yaboot.conf: Unknown or corrupt filesystem
by Marcus Mae 29 Jul '09

29 Jul '09

Hi, Openbios dev list, I'm wondering if it is possible to run ppc virtual machine on x86_64. I execute the following: qemu-system-ppc64 -vga std -cdrom /home/marcusmae/Download/OS/Fedora-11-ppc-DVD.iso -hda f11_ppc.qcow2 -m 1024 , and this brings me to coffee-colored openbios room, inviting to boot from somewhere. I type: boot cdrom which gives me cdrom:0,\ppc\chrp\yaboot.conf: Unknown or corrupt filesystem Welcome to yaboot version 1.3.14 (Red Hat 1.3.14-12.fc11) What's the problem with it? I'm sure that it's an iso of ppc build of fedora. Thanks!

[PATCH] sparc64: implement OF memory manager
by Igor Kovalenko 28 Jul '09

28 Jul '09

This patch implements OF memory manager. I used arch/ppc/qemu/ofmem.c as a starting point, future plans in ofmem area would be to migrate common parts from working implementations (ppc and sparc64) into common module. Client interface handler now uses ofmem implementation instead of walking hardware translation tables. Since setup code in entry.S does install it's own translations ofmem initialization routine simply copies entries from hardware. Properties "available" and "translations" are then populated as needed. This implementation passes boot test with no visible changes on screen for HelenOS-0.4.0-sparc64.iso Linux boot does not get any further with this patch due to conflicts with memory mappings in low memory region.

Checksum error on dictionary files
by Ed Stafford 15 Jul '09

15 Jul '09

I built OpenBIOS v1.0 on my Fedora 10 PPC system using gcc 4.3.2. After changing a couple of assembly instructions from 'ba' to 'b', I was able to compile openbios into a binary. The problem is, when I try to run the openbios-unix program with the supplied dict file, I get the following: bash-3.2$ ./openbios-unix openbios-unix.dict Checksum invalid (65a824b7)! not supported. bash-3.2$ Any idea what corrupted the file?

PATCH: Minor tweaks to dump word output
by Mark Cave-Ayland 12 Jul '09

12 Jul '09

Hi everyone, This small patch improves the output of the dump word by adding a preceding carriage return to the dump output, and forcing addresses to be displayed unsigned. Without the unsigned output fix, addresses tend to be displayed as negative numbers working with openbios-unix.

[PATCH] sparc64: fix registers dealing with client
by Igor Kovalenko 12 Jul '09

12 Jul '09

Hi! This patch improves previous proposal and adds: - save/restore global registers across client interface calls. Since OS kernel generally has it's own idea of what the ABI is we have to follow this requirement. - adjust stack to allow using unoptimized openbios build with linux kernel. Linux provides only 128 bytes on stack which is not enough to save arguments by code generated with gcc -O0 - fix switch_to so it actually could be used to switch to client image. context pointer must be volatile to prevent gcc optimizing out stores to it.
