-zenmm seems really great. I was able to run some emerges, do some file IO, use amarok all at the same time and not a lockup at all.

Is there anything special in the -zenmm kernel that should be turned on/off for best performance??

EDIT: the hdaps seems to be throwing that missing 'blk_freeze patch missing' error. I have it HDAPS and tp_smapi built as modules.


nope

thanks @rmh2093!

Not sure if it is a placebo effect but I am recompiling glibc and -19 niceness and using amarok, web browsing, have a few ssh open, and I have hardly any bumps in amarok. Playing very smoothly. With firefox3, amarok and thunderbird open on xfce I am using 620MB RAM with swap only being touched about 4MB. This kernel feels nice, like I said probably placebo but not sure.

Now if I could get conky to stop stealing +/-25% CPU I would be happy lol. ;)

Hm, hdaps should work, it has tp_smapi patch in it :? . The hdaps.c from normal zen and zenmm are identical, hence it should be working... >_>
I'm using normal zen on my thinkpad, so i'm not sure whether it works here or not.
I'll look into it though.

well i will extend your thanks to cheater-conrad, he helped out with this release also....

but no its not placebo, -mm kernels usually have lots a cool memory management changes and other general goodies that make for a much smoother kernel experience, its like a playground for everything before it gets into vanilla, but because its not tested by normal users it doesnt get the bug testing that a vanilla kernel does, as a result, cool features can sit in -mm for many kernel revisions and even get lost

Will there be ebuilds available for zenmm-sources in zen-overlay?

yes, eventually :lol:

I'll be uploading 2.6.26-rc8-zen1 soon (it's available via git for now, not tagged yet, need to check some stuff first).
zenmm needs some tweaks to the eclass, so soon(tm).

@dodo this is what happens when HDAPS tries to start:
Code:

cosmo ~ # /etc/init.d/hdapsd start
 * No protect entry for sda!
 * Make sure your kernel is patched with the blk_freeze patch
 * ERROR: hdapsd failed to start


I have this:
Code:
cat /usr/src/kernel-mm/.config | grep TP_SMAPI
CONFIG_TP_SMAPI=m

cat /usr/src/kernel-mm/.config | grep TP_SMAPI
CONFIG_TP_SMAPI=m


and this
Code:
cosmo ~ # lsmod
Module                  Size  Used by
....
tp_smapi               24536  0
hdaps                  12616  0
thinkpad_ec             6288  2 tp_smapi,hdaps
....


That probably isn't that helpful to you though.
Thanks in advance.

Does anyone use any of the kernel options for Advanced Congestion Control? If so what algorithms have you tried?

Ah yes, i forgot about cko >_> I'll be in git in a sec.

Could someone also check if reiser4 is working properly? Backporting it from -mm is a right pain...

EDIT: It seems to be working for me, but i'm not sure for how long... :lol:

EDIT2: it hardlocks here with io on reiser4 after some time here, proper fix (i have a dirty one working now btw) hopefully coming soon as hotfix2.

Ok, reiser4 is fixed (thanks to conrad).
Hotfix2 with the fix is available; get it either from git or through hotfix-zen app.

Hmm, how do I fix this? :|
Code:

asplode linux # git pull
(...)
CONFLICT (content): Merge conflict in include/linux/fs.h
Auto-merged include/linux/mm.h
Auto-merged init/Kconfig
CONFLICT (content): Merge conflict in init/Kconfig
Auto-merged kernel/printk.c
Auto-merged kernel/sysctl.c
Automatic merge failed; fix conflicts and then commit the result.

asplode linux # git checkout -f
Your branch and the tracked remote branch 'origin/master' have diverged,
and respectively have 119 and 780 different commit(s) each.

asplode linux # git pull
You are in the middle of a conflicted merge.


EDIT: never mind, I need to read older posts :|
