    Aborting...

...while applying "bfs357-test.patch" after "2.6.35.7-sched-bfs357+schedule_groups_as_entity-1.patch".
If I apply only the latest patch, it asks for 2.6.36...

Update 1: It works like this:

1. Apply "2.6.35.7-sched-bfs-357.patch"
2. Apply "bfs357-penalise_fork_depth_account_threads.patch"

Builds good like that on 2.6.35.

Update 2: Con has just released a "combo" of those two I wrote above. Testing it out.

Re: new exciting features in BFS (making desktop interactive at any load)

Further investigation revealed this patch didn't work quite how I thought it did, but still offers significant advantages. See the newer posts on hierarchical tree based penalty.

so i think better to use "bfs357-penalise_fork_depth_account_threads.patch"

in /proc/sys/kernel/

group_thread_accounting - groups CPU accounting by threads
fork_depth_penalty - penalises according to depth of forking from init

seems this patch contain functions of "2.6.35.7-sched-bfs357+schedule_groups_as_entity-1.patch"

Re: new exciting features in BFS (making desktop interactive at any load)

i've tried both of them and i can't tell any difference.

the browser got the same speed no matter i was compiling something or not.

but i got some really wired problem with the these patches. such as gnome-panel always can not load all applets successfully, some applets can not loaded readomly.

it looks like panel itself do not wait applets to load. that's not acceptable. so i have to fallback to bfs357  without any of these two patches.

+1 - had the same problem with fusion-icon.  Dropped by to ck1 + bfs357.

Re: new exciting features in BFS (making desktop interactive at any load)

I get the problem, that the desktop sometimes don't react to the right click of the mouse. For exampel when I try to open a link in chromium in a new tab, I click with the right mouse button on a link, but the menu don't appear or sometimes it appears after a few seconds. Very strange!

Re: new exciting features in BFS (making desktop interactive at any load)

according to his lastest blog post( i didn't read it carefully), seems the problem i met must be fixed by the application itself. so i have to report to upstream, am i right?

Re: new exciting features in BFS (making desktop interactive at any load)

Mmh, strange. Two days ago I tried the patch with the zen kernel and I had a few problems (already talked about a few comments earlyer). Now I tried the newest pf-kernel with this patch and my system runs very snappy. Think I misconfigured anything with the zen-kernel.

Desktop is reacting as if there's no load at all. I love it!

Are you sure the new BFS 357 is included? I compiled the kernel from the AUR, but sched.h says
printk(KERN_INFO"BFS CPU scheduler v0.323 by Con Kolivas.\n");

Maybe you did not pull from git? Mine is:

printk(KERN_INFO"BFS CPU scheduler v0.357 by Con Kolivas.\n");

Re: new exciting features in BFS (making desktop interactive at any load)

I did, but first I compiled the experimental branch, and later it turned out, it is in the stable branch... not logical, but hey.
