BFS in Fedora 16

[Zerix01]

Does anyone know of a repo that will give me a kernel using BF scheduler in Fedora?

I'm back to running the F@H GPU client in Linux and I NEED BFS in order to get the right speed out of it.

From what I can tell, you need to patch the kernel and then build from source.
http://ck.kolivas.org/patches/bfs/

I'm not sure if BFS is selectable with a clean kernel.

Ok I am very stuck on this patching thing.

I started to follow these instructions
http://www.howopensource.com/2011/08/how-to-install-compile-linux-kernel-3-0-in-fedora-15-and-14/

But I downloaded a 3.1.0 kernel on my own. I only went as far as extracting the source to /usr/src/ since the patching should be done before the compiling.

Then I'm following these for the patching
http://www.howopensource.com/2011/08/how-to-upgrade-or-patch-latest-kernel-3-0-in-ubuntu-and-fedora/

I'm not sure if I downloaded the correct patch or what now. I just went with the general CK patch, more specifically 3.1.0-ck1-broken-out.tar.bz2. I don't know what he difference between the broken out one and the other one.

Then I get this
[zerix01@Deepthought linux-3.1]$ sudo bzcat /mnt/md0/kernel/3.1.0-ck1-broken-out.tar.bz2 | patch -p1

Perhaps you used the wrong -p or --strip option?

So I see what look like failures and it is prompting me for a file to patch. So now what?

[Shelnutt2]

you should be in the /usr/src/folderwithkernel/ when applying the patch. Is that were you are?

Try -p0 also.

If you still can't get it I'll tar and upload 3.0.4 ck kernel sources as I have those installed but not using them in funtoo.

Just in case:

Looks like wrong patch or kernel sources. I gotten the "hunk FAILED" and "saving rejects to file" bull before with Debian Lenny in 2010 until I got different files. I wouldn't be surprised if it's a wrong or bad patch file.

When I was adding RT support to Debian Lenny in June, 2010.
