2.6.15-no4 "Love is Dead"
Tribute to love-sources on valentines day!
-----
NICKSCHED TIMESLICE BUG
This will be resolved very soon, with a patch to apply, until then, you need to edit the following file to 16,32,64,128, or 256 - IF YOU ARE USING NICKSCHED

Code: Select all

# nano /sys/cpusched/nicksched/base_timeslice (assuming you are using nano)

You need to change the value that says '256' to the value you want, by default in the Kconfig it is set to 128.
-----
PATCH TO MAKE NICKSCHED THE DEFAULT CPU SCHEDULER
This was intended to go into mainline no-sources, but it did not, so here is the patch (it is not needed, but it will be used in the future)

Code: Select all

# cd /usr/src/linux (clean kernel, assuming make clean has been ran)
# wget bfgraphics.net/nicksched_default.diff
# patch -p1 -i nicksched_default.diff

This is not really a *fix*, it is what will be done in all future -no releases, nicksched can simply be made default in the, General Setup > CPU Schedulers, menu
-----
Due to valentine's day, a lot of the text in this post will have a pretty indigo color
-----
New release, RECCOMENDED UPRGADE!, fixed suspend2 issues, upgraded to vanill 2.6.15.4, added a few fixes from -mm (e.x. a bluetooth fix), Added eCryptfs support,FIXED NICKSCHED TIMESLICE!, by adding it to the CPU Schedulers kernel config, and setting the default to 128*, Fixed hdaps in mm, added lufs support, added the mapped watermark patch from -ck

Nicksched default scheduler patch.

It is not needed, but I totally forgot to include this one in the menuconfig patch :X

the patch just enabled nicksched as the default in the Kconfig

you are using an outdated suspend2 patch

[Zyne]

sweet!
Love-sources have always been my favourite patchset


Thanks for the newest update!


edit: there appears to be something wrong with the CIFS module... Whenever I try to access a windows share, my computer just freezes... It's not even accessible through ssh anymore.

[cheater1034]

:X I downgraded because the 2.2 one I was using appeared broken. When the next release of no-sources comes back in (2.6.16 release probally) I will hack up a suspend2 patch for 2.6.16

edit: there appears to be something wrong with the CIFS module... Whenever I try to access a windows share, my computer just freezes... It's not even accessible through ssh anymore.

I do not use cifs, but it is right for me to assume the git-cifs patch from -mm is breaking it. You may wish to try installing the module seperately, for now, until this is cleared up.

Something to consider: Instead of using MD5 hashes (which have been cracked), try SHA256.

I've switched all the hashing work I can over to SHA256 and lately a number of other folks have started switching to SHA256. On Gentoo, as far as I know there isn't an SHA256 hashing utility installed by default, but more recent versions of md5deep support SHA256 and a number of other hashing schemes. You could provide them side by side, but most people who are doing serious integrity checking have switched to SHA256.

I will probally do this.

I broke my system accidently, as I was attempting to downgrade glibc from 2.3.90* to 2.3.6. So I am reinstalling currently.

When I get my system up (by tomorrow w/ X+OB3) I will work on 2.6.16-rc3-no1, Which I planned to work on initially, before I broke my system :X

Hello!
I noticed that if i do a cat /sys/cpusched/nicksched/base_timeslice it shows me 256 although I set it to 64 in kernel config.
How can I fix this?

Really? I will research that issue, it should not look like that.

you can change it manually to 64 via that file, it should work.

I will double check the kernel config to make sure it is configuring the right option.

Yep, Vla is right.........now that I looked, it also says 256 but I've set 128 in kernel configuration

[cheater1034]

marked as bug, posted fix.

Thankyou very much

There will be a patch to fix this soon!

[Tiger683]

lol, an easy one ....

If you put something in the Kconfig, you should use it in the code too

Pls cheater update this series to 2.6.15.6 version

[mirek]

Have anybody got problems with suspend2 with gcc4.1 My kernel

Code: Select all

# uname -r
2.6.16-rc5-no3

I have upgraded gcc and xorg-x11 to v.7.0 and Suspend2 is not working now.

[mbar]

Suspend2 is working in 2.6.15-noX series only. That's why I asked for updating it a little...

[cheater1034]

that is expected, I will re-write a patch for 2.6.16-no1, suspend2 works with THIS and previous versions only.

The reason is because the entire 2.16.x series was based off of -mm, and there is no suspend2 patch for -mm, so I had to rewrite major chunks of a few major suspend2 files, and I couldn't test it myself.
