PATCH 1/1 CFS scheduler, -v17

i'm pleased to announce release -v17 of the CFS scheduler patchset.

The rolled-up CFS patch against v2.6.22-rc4, v2.6.22-rc4-mm2, v2.6.21.5 or v2.6.20.13 can be downloaded from the usual place:

http://people.redhat.com/mingo/cfs-scheduler/

-v17 includes a bigger change: the CFS-core changes in preparation of the group-scheduling feature, written Srivatsa Vaddagiri. Dmitry Adamushko provided cleanups and further generalizations to this code and the modularization of CFS has been further enhanced as a result. To users, these changes are mostly invisible.

Changes since -v16:

- lots of core updates to support group scheduling, and related cleanups. (Srivatsa Vaddagiri, Dmitry Adamushko)

- tuned the runtime-limit up a bit, based on relentless testing done by Tobias Gerschner.

- the new, precise load-calculation method for SMP balancing has been further enhanced, and is now active by default. (Dmitry Adamushko)

- fix SCHED_IDLEPRIO support (based on feedback from Thomas Sattler)

- further updates to /proc/sched_debug and /proc/PID/sched

- more cleanups

As usual, any sort of feedback, bugreport, fix and suggestion is more than welcome!

Ingo

The code in question is really strange:

#ifdef CONFIG_SMP
...
static inline int cpu_of(struct rq *rq)

#ifdef CONFIG_SMP
	return rq->cpu;
#else
	return 0;

#endif
}
...
#endif

Patch follows, only compile tested, hope it helps.

------

[PATCH]: Fix undefined reference to `cpu_of'

cpu_of() is defined inside a CONFIG_SMP #ifdef/#endif but called by !CONFIG_SMP code.

This patch fixes that by creating a !CONFIG_SMP version of cpu_of().

I guess this code is missing #ifdef CONFIG_SMP ?

yeah - it affected the .22 patches, the .21 and .20 patches compiled and worked under !CONFIG_SMP too. I updated the .22 patches with the fix below.

oops :-) That was due to !CONFIG_SMP.

Patch follows, only compile tested, hope it helps.

Thanks! I fixed it in a slightly different way: moved the cpu_of() thing outside of the #ifdef CONFIG_SMP section, as per the patch below. I've updated the -v17 patches with this minimal fix and have verified that the !CONFIG_SMP kernel boots and works fine.

De : [email protected] [mailto:[email protected]] De la part de Ingo Molnar Envoyé : 14 juin 2007 18:49
i'm pleased to announce release -v17 of the CFS scheduler patchset.
The rolled-up CFS patch against v2.6.22-rc4, v2.6.22-rc4-mm2, v2.6.21.5 or v2.6.20.13 can be downloaded from the usual place:
http://people.redhat.com/mingo/cfs-scheduler/
-v17 includes a bigger change: the CFS-core changes in preparation of the group-scheduling feature, written Srivatsa Vaddagiri. Dmitry Adamushko provided cleanups and further generalizations to this code and the modularization of CFS has been further enhanced as a result. To users, these changes are mostly invisible.
Changes since -v16:
- lots of core updates to support group scheduling, and related cleanups. (Srivatsa Vaddagiri, Dmitry Adamushko)
- tuned the runtime-limit up a bit, based on relentless
testing done by
Tobias Gerschner.
- the new, precise load-calculation method for SMP balancing has been further enhanced, and is now active by default. (Dmitry Adamushko)

Quoted 8 lines

- fix SCHED_IDLEPRIO support (based on feedback from Thomas Sattler)
- further updates to /proc/sched_debug and /proc/PID/sched
- more cleanups
As usual, any sort of feedback, bugreport, fix and suggestion is more than welcome!

Fedora 7 & Debian Sarge 3.1 kernels using latest CFS v17 available at http://linux-dev.qc.ec.gc.ca/
YUM users: http://linux-dev.qc.ec.gc.ca/kernel/fedora/alt-sched.repo

Thnx Ingo & cie.

Hi everyone,

I'm just writing to say how impressed I am with the new CFS scheduler. I've been following it's development from the first patch, right up to now (running on the latest vanilla kernel I could!) and I can honestly say I've never had such a responsive experience.

I'm currently writing a major patch to the ext2 file-system driver, as part of a University project - it involves a lot of kernel rebuilds as I'm testing the patch in UML. I've had a couple of kernel compiles happening simultaneously (on my moderate single CPU PC), and tried out a few make -j12's, and I'm amazed at the difference the new scheduler makes.

I've got quite a few instances of Firefox (whoops, Iceweasel) open, I'm listening to music and theres a few other apps running (like KNode the newsreader) and the interactivity response has been excellent.

In conclusion, well done to the scheduler people and I look forward to seeing this go to mainline.

(If there's anything I can do to help, I'd love to throw a few patches at the mailing list ;)
