Anyone use the ck/bfs patches on your kernel?

I've never actually tried using these. I'm not even sure what all patches I need. http://users.on.net/~ckolivas/kernel/

Anyone use these and can share their experience and/or tell me how I'm supposed to use them?

I use the CK patch to compile my own kernel. I always compile my own, fully customized. Just a practice that I follow.

Step 1. Download the patch.

Quote:

http://ck.kolivas.org/patches/3.0/3....h-3.10-ck1.bz2

Step 2. Download the kernel source and extract it to my /home directory.

Step 3. Extract the patch in the /home/linux-3.10.x directory and then patch the source.

Code:

patch -p1 < patch-3.10-ck1

Step 4. Then copy over the config from /boot and run

Code:

make menuconfig

Step 5. The usual steps...

After updating the bootloader & booting with your new kernel. You can check if you're using the BFS Scheduler by issuing the following command in your terminal application.

Code:

dmesg | grep scheduler
...
[    0.380500] BFS CPU scheduler v0.440 by Con Kolivas.

Good Luck!

Thanks for the post! I pulled the 3.10.18 sources from kernel.org, and am now building. Will post later to tell how it went.

Well, I've been running 3.10.18 for approximately a day, and have noticed no ill effects, and at least a slight performance improvement. Of course, I haven't been compiling software heavily, either.

Oh, well. It was an educational experience.

So I've been using the CK patchset with BFS for the past three or so weeks. My review is, meh. BFS feels negligible/unnoticeable compared to the old scheduler for me, and I've already had two random full system lockups that I had to power off to kill. I don't even remember the last time that's even happened me, let alone twice in one month. Also I don't use hibernation features, but I know for a fact from Con's own site that hibernation/suspend doesn't work with the 3.10 patchset.
