Re: [PATCH] xnu

[Joey Korkames]

I have your whole patch series applied and have been trying to use this to 
boot the PureDarwin 9 kernel (on various x86 32 & 64 bit machines):

menuentry "PureDarwin 9 (phcoder efiemu)" {
       #efiemu_loadcore /osstore/STAGE1a/grub2/efiemu32.o
       efiemu_loadcore /osstore/STAGE1a/grub2/efiemu64.o
       efiemu_pnvram /osstore/STAGE2/DARWIN/pnvram_vars
       efiemu_acpi
       efiemu_prepare
        set fsb=667
       xnu_kernel /osstore/STAGE2/DARWIN/live/mach_kernel -v -s rd=md0
       xnu_mkext /osstore/STAGE2/DARWIN/live/System/Library/Extensions.mkext
       xnu_ramdisk /osstore/STAGE2/DARWIN/darwin1.img

}

where darwin files are from:
http://xref.puredarwin.org/puredarwinnano0df46.tbz2

where pnvram_vars is a blank file and darwin1.img is an disk image with an hfs partition in it (still working the layout of that fs per 
http://www.insanelymac.com/forum/index.php?showtopic=144128&p=1023069&#entry1023069)

I doesn't matter if I set gfxterm/vbe_mode/fsb or not, the best I get is an 
immediately panic'ed kernel.
I can only see the output on a CRT monitor of a 2CPU(x4 core) EM64T server 
(black text on a _dark_ blue background - very hard to read).

A Xen HVM freezes up and the text (if any) is invisible, as well as on several laptop 
LCDs (hard to really test these platforms since can't "see" the crash).

It seems xnu_mkext works because the output differs when that line is ommited 
(complains abount not having an /Extensions for ACPI)

Do you have any pointers to improve the video output?
