since the zen kernel has stopped showing up in portage, I thought
I'd try the git route,

But when I run:

Code:
git clone git://zen-kernel.org/kernel/zen-stable.git zen-sources


all I get (after a while sometimes, sometimes right quick):

Code:
Cloning into zen-sources...
fatal: read error: Connection reset by peer


I know nothing about git, so any help would be appreciated.


Site appears to be down at the moment. Although the online git repo appears to still be browesable (but I get the same error as you when trying to sync)

there is some syntax error only visible when CFS_BOOST option is enabled that breaks build.

disabling the option or switching to BFS works it around.

I'm lost about this

in zen-sources-2.6.36 stable I still get this error when BFS is default scheduler;
plus I just don't see any CFS_BOOST options at all :?

("grep BOOST .config" returns nothing)

i got an error on include/linux/sched.h at line 1216, here's the code at that line, when enabling CFS_BOOST feature.

Code:
#ifdef CONFIG_SCHED_CFS_BOOST
        if (p->policy == SCHED_NORMAL || p->policy == SCHED_BATCH)
                sched_privileged_task(p);
#else
#endif

OK - after downloading 2.6.35 stable again it will compile (had to
upgrade nvidia drivers to 2.60.xx) ...


EDIT: actually, it appears in my case that I get the
cpu_stop_cpu_callback error if I try to build BFS,
and I get a different error if I enable the CFS_BOOST

sticking with plain old CFS enables compilation

Some of you asked why git cloning resulted in errors.

The problem was due to popularity of some new stuf in latest kernels. Lots of people tried to git pull/clone at the same time. That resulted in either slow pull or a refusal. Hopefully we will soon upgrade RAM on the server and solve this problem.

But for now, be patient and if pull/clone/... fails try a bit later.

Is BFS currently broken for zen-stable? This seems to indicate so ...

  CHK     include/generated/compile.h

yeah - seems so

and according to the source they dropped also sched_stoptask.c from upstream ???

these probably need some fixing

Actually I checked out 2.6.36-zen0 and pulled ck(which is BFS) a few days ago and it compiled fine. Also there's a new commit called "CFS sched fix" so try syncing stable again..

I've been lucky. This message is being typed on a machine running 2.6.36-zen0 wuith BFS. Unfortunately my git isn't working. It hasn't for the past few days...getting connection reset by peer. Is there an git issue?

Cheers,
Pappy

I dont understand: Is it now per TTY or per session?
Both is mentioned, but I think I've read that the in-kernel patch does per TTY ?!?!

oh - come one !

did you miss the v4 ? :P (and the non-existant v1 to v3 for per-session patches)

that means they made a step from per TTY to per session ;)

Hey guys,

could you add the favicon from http://zen-kernel.org/ to http://git.zen-kernel.org/ as well? as i use just the website's icons in my bookmark toolbar in firefox this would make it a lot nicer instead of having that standard website icon :-)

thanks

today git is not responding, but it looks like there's an easy way to get a snapshot of master using cgit:
Code:
wget http://git.zen-kernel.org/zen-stable/snapshot/zen-stable-master.tar.bz2


FYI (you probably already know, as it made the frontpage of lkml.org), looks like there are some fixes (and others will come) in David Miller's tree
http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.git;a=summary

EDIT: http://lkml.org/lkml/2010/11/26/440

please also consider adding the following 2 patches which should help with the per session task groups:

Re: [PATCH 1/2] sched: normalize sleeper's vruntime during group change
Re: [PATCH 2/2] sched: use the old min_vruntime when normalizing

thanks ! :)

Hi, guys) I have some problems..

After latest zen-stable updates my system keeps crashing after about 1 minute uptime.
At kernel panic log it says something about reiser4 and it's cryptocompress plugin.
