Author: mcayland Date: Sun Oct 24 21:55:27 2010 New Revision: 918 URL: http://tracker.coreboot.org/trac/openbios/changeset/918 Log: Use wrappers around all romvec functions on SPARC32 to flush register window and preserve global registers. This appears to resolve issues with OpenBIOS crashing when calling OBP functions through the romvec interface due to stack/register issues. Note that this patch also implements pv_printf() and pv_putstr() which appears to fix issues with displaying error messages during Solaris 8 boot.

Dell M1730 support
by X3lectric Oct. 23, 2010

Oct. 23, 2010

Hi Maybe this has been asked or answered, but searching around I could not find a compatibility list, so I apologise in advance for the numbness of the brain. Please could anyone let me know if the Dell laptops in specific the M1730 is supported by the openbios and if there are any binaries ready to be flashed for this machine. Thx in advance.

Btw, can you explain how the physical address of an ebus device can be calculated? Looks like they are relative to the ebus beginning and then to PCI, but what constants define the offsets? info qtree doesn't show the physical addresses either. > Is Netra-T1 OK? Wanted to check whether the current ebus mappings match Netra-T1 or U5, but haven't succeeded. -- Regards, Artyom Tarasenko solaris/sparc under qemu blog: http://tyom.blogspot.com/

Author: mcayland Date: Mon Oct 18 21:32:16 2010 New Revision: 915 URL: http://tracker.coreboot.org/trac/openbios/changeset/915 Log: Fix the placing of Forth arguments on the stack when calling obp_fortheval_v2() via romvec on SPARC32.

I have begun doing work with OpenBIOS. I was wondering if it is possible to compile OpenBIOS for PowerPC on Mac OS X? If not, what Linux distro should I use? Any advice would really help.
