[GPL]2.6.29.6 CFS Kernel V9 12/10/10

I put this kernel together with the direction of Decadenc3(Thanks again and I hate github by the way lol). It is basically the same as the bfs kernel without the bfs which makes it a little more stable in my opinion. It is set up for interactive governer which decadenc3 tells me works very nicely without the bfs.

V2
Fixed commit conflict which may have caused kernel panic(which means hopefully no more reboots for those who had problems)
V3
Lowered starting voltage(undervolting)
V4
Re-enabled low memory killer
V5
added tun.ko file (untested)
kanged some more commits from some better kernel devs then me(see github source for commit changes)
V6
added cifs support
Camera freezing fix
Other updates from backports of .32 and .34 kernel stuff
V7
never officially released
added loop support
V8
Smartass governor added
Updated kgsl, better graphics performance
updated interactive governor
Download CFSv8 from here.
V9
Removed cifs support and reverted to the linux toolchain for compiling. I think that these were the changes in V6 that caused some wifi and failed boot problems for some users. Nothing has been changed in wifi so I think this is what the problem was but for those that were having trouble you'll have to let me know.

Flashing this kernel will cause issues with Froyo apps2sd. Froyo apps2sd uses cyrptoloop to mount the apps on the sd card. The kernel has the cryptoloop module compiled seperately so it needs to be activated for apps2sd to work. This can be done manually by typing insmod system/lib/modules/loop.ko and then insmod system/lib/modules/cryptoloop.ko. This can be put into a script and run at boot by your rom dev if they choose to include this kernel.
More thanks to Decad3nce and all the other great kernel guys that i can pull commits from to put this together.

More Info on Smartass governor

Technical Details-originally posted by erasmux

smartass governor - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 - why?! - it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!

Just thought I would throw this "decoder key" out here for historical purposes - the Decadenc3/Conap kernel made its way into lots of different ROMs...

...so, if you are not sure or have forgotten which kernel is in your ROM, do a "adb shell uname -a", and you should be able to match these:

Note the similar strings for CFSv8 and CFSv9 - make sure to check the dates carefully.

And of course my source for this if any of you would like it.

Also you can check out my Froyo rom here.

If I understand your question correctly, none of the above. You are not running the CFS kernel at all. I'm no expert on this but I believe you're running the kernel which was originally made for use with more stock (HTC Sense, for example, but not necessarily just that) 2.1 ROMs for the Eris.

People have tried using Conap's CFS kernels with 2.1 ROMs but at least back a while, it was reported that it seemed to slow things down in that case. It seems to work better with 2.2-based ROMs like Cyanogen Mod 6.x-based ones.

What ROM are you running?

Someone please correct me if I'm wrong or if there's more information which should augment what I said.

The download links on the first page arent working, is there an alternative download site? I need CFS v6 (v7 or v8 would work if they are mostly the same i suppose)

I did a search in your CELBFroyo thread and couldn't find a related hit.

I'm "assuming" that you have such a script run at boot in CELBFroyo. After all, I haven't experienced any problems with Froyo's Apps2SD that I'm aware of, but I just wanted to be sure.

Thanks!

yes this is taken care of in my rom

I see. well if this is the case then can anyone maybe tell me an easy way to change the governer without opening up terminal? like through an app or widget maybe?

Well this looks like a good place to plug my new app http://xdaforums.com/showthread.php?t=867667...this will let you change the governor....I actually wrote it because so many people were wanting to change away from the smartass governor so it should be just what you want...
