BFS patch for 2.6.35 (git linus kernel)

legolas558 · 2010-07-20 08:54:36

Con Kolivas mantains a great patch for the linux kernel (check it out: http://ck.kolivas.org/patches/bfs/)

However he can't port the patch every while to the latest kernel, so he often waits for stable releases.

Since I really need to use 2.6.35 and don't want to miss BFS, I have ported his patch to 2.6.35, here is the result:

Please notice that this is not guaranteed to work, although I am using it right now without any glitch.

Enjoy!

Mind elaborating on it?

I have i855GM rev 02 which suffers of a bug requiring another patch to work; although I could use 2.6.34 I prefer working with latest git tree to help developers fix the intel bug definitively.

I thought so.
I have a 845 so maybe you could fix mine too ;P

Good luck.

you should definitely get in touch with those guys... duplicate efforts...

Yes I could probably make some git merge using their repo and linus repo, but a single-file patch is much handier

2.6.35 should be out later this month or early August.

Do you plan to maintain a linux git port of BFS?

Theoretically, yes, because I will always use the git linus tree for myself. But if I find major troubles in mantaining the patch I will wait for Con Kolivas to fix it. Also I will always use Con Kolivas' official patch when available.

I have rebased the patch against 2.6.35-v6, and now it works because the previous version missed the necessary fixes to sched_bfs.c

legolas558 · 2010-08-12 10:03:25

I have just updated the patch to work with the recent changes to slow-work.c and workqueue.

Enjoy

BFS patch doesn't work anymore on latest kernel (it has been some week now); I suppose there is some new subsystem which needs an adapted counterpart in the BFS patch.

The system stucks some time during D-BUS initialization and the hangup is basically due to timers never releasing (some preemption issue?)

Edit: Con Kolivas has provided a patch for 2.6.35 on 7 August, check it out. However it doesn't work because misses the fixes for slow-work.c and oom_kill.c

no problem with latest BFS on 2.6.35.3

I mean with latest GIT linus tree
