I'd like to be able to build a kernel that will boot on the GC, but I'm not sure where to start. I know I need kernel source, but what version works with the patches in CVS? About CVS, how do you apply the patches? They aren't like conventional patches that I'm used to (ie-patch -p0 < patch.diff). Any information would be greatly appreciated. Thanks. - Mike Goggin |

One of two ways (asumming you've unpacked a vanilla kernel): 1) Using GNU diff-style patches. These are on the project download page. 2) Checking out either a tagged release or HEAD from CVS, and copying that over your vanilla tree. Something like: cvs -d:pserver:ano...@cv...:/cvsroot/gc-linux co -r linux-2_6_N linux cp -r linux/* linux-2.6.N Where N could be 1-7, depending on what kernel version you're working with. To check out a snapshot of the latest stuffi (HEAD), drop the -r option entirely. Arthur |

Cool, thanks. Now, one more question...
I downloaded the 2.6.7 source, and got it patched to support the GC.
make vmlinux compiles fine. But make zImage.initrd gives me the
following error:
[tosk@cavalier ~/linux-2.6.7]$ make zImage.initrd
make[1]: `arch/ppc/kernel/asm-offsets.s' is up to date.

No. The -0x80000000 is not a valid incremental value for --change-addresses.
Good catch. Funny how this doesn't barf on making zImage; the same funkiness
appears there as well.
Looking at the build output, I assume that you're building on a PPC host?
What version of binutils (objcopy --version)? In any case, this patch,
hackish at best, should fix things. Please confirm.

Great. I'll confirm it as soon as I get YDL back on my Mac...or compile the kernel from Mac OS X. Either way, I'll let you know ASAP. - Mike Goggin On Jul 20, 2004, at 6:32 PM, Arthur Othieno wrote: > On Sat, Jul 17, 2004 at 10:36:40PM -0500, Mike Goggin wrote: >> I downloaded the 2.6.7 source, and got it patched to support the GC. >> make vmlinux compiles fine.

Indeed. The patch DID work. I now have a working kernel. I don't actually have a BBA for my GC yet, but I grabbed a GC emu off the net and it works well enough to load the kernel and let me know that it compiled properly. Thanks for the help Arthur. - Mike Goggin PS-I never answered your questions, so: Yes, I built it on a PPC host (eMac 1GHz, 512MB RAM); and I have no clue what version of binutils I was using. It was whatever version came with Yellow Dog Linux 3.0.1. Though, after applying the patch, the kernel was built using Gentoo Linux (2.6.1-benh1). If you'd still like to know, I can grab the bintuils version for you for Gentoo.
