[size=+1]== New 2.6.34.7 kernel build; Supporting 614OC ==[/size]

Notice: There are newer versions of this kernel please see kernel 20110222 for the most resent and links to all previous versions of the kernel including this one

EBI0 (32b) for 2.22.* radio users:
ezBiffTestKernel20101024-ebi0_S.zip
MD5: 9e7d943e44c2dab647cbda10ae3d6a40

EBI1 (32a) for 3.22.* radio users:
ezBiffTestKernel20101024-ebi1_S.zip
MD5: 209628962651fe7a8037dcca2b7fab75

Anykernel format thus will work on most CM6 builds and my MT3G froyo test rom. (Built for biffmod)

This kernel includes the current pershoot 2.6.34.7 codebase + some configurations/patches by myself.

Some key features of the build:
* Extra 1MB ram for ebi0 dream users
* *New* tweaks to low memory killer both from upstream and myself (will hopefully make compcache [and in turn swap] run smoother for you)
* Default speed 556/245 but can be set to 614/122 via setcpu

(FYI: I run the kernel at 595)

[size=+1]== Source Code ==[/size]

Build from tag:

[size=+1]== Previous Builds: ==[/size]

October 6th 2010 (ebi0/ebi1) here 595oc
October 17th 2010 (ebi0 only) here 595oc w/ 1MB ram

Is this the same one that was on the BiffMod Nightly?

If you are talking about my build of it, nearly the same (lowered the default CPU speed some from 576 to 556.. however I think the freezes I'm getting are the nightly not my kernel.. since it unfroze on me this last time with nothing in dmesg/kmsg)

Of course very few know of that build while others with or without biff may want a binary of the kernel.

Okie dokes, thanks for the update and clarification :D The new one seems a bit faster :D

as far as I can tell, the 34.7 default (13th Sep) multitasks a hell of alot better. Opera, mms, contacts, facebook everything stays open. With this modified one, it doesn't.

I would like to have an updated 34.7 from pershoots github but ive no idea where to start

There are some changes in low memory killer pushed into both kernels form CM; I've worked on it some but it will act differently from before the patch.

With that in mind its important to look at your minfree levels (if you are using swap lower them) with the new kernels; and potentially increase snappiness. Such actions will change the behavior some maybe more to your liking.

Otherwise you can try one of my past builds as they use the older code.

That said the bases for building the kernel is here

after running make to build the kernel run:

Code:
mkdir build
make modules_install INSTALL_MOD_PATH=`pwd`/build
then the modules and associated files will be in ./build/lib/modules

Hi guys!

I would need a bit of a help... I tried to port the RBM2 firmware to our G1, but I failed. Jcarz told me it is a kernel problem, but sadly flashing any pershoot kernel haven't fixed it.

The problem is, I don't have a clue about Android's kernel management, nor about porting it, so I would need some hand (or someone) who can help me fix it.

For the files, and info, here: http://xdaforums.com/showthread.php?t=819154

For anyone who helps me: thank you very much!

Hi, I tried using "newest (10/14/2010):
2.6.35.7 32A/B (only oc710 so most of you will need to set your max frequency in init.d or whatnot)" and my phone doesn't boot, naturally, beings that it is scaled to 710. How would I go about editing init.d to only allow for a max of 614?

    Anykernel installers for use on android 2.2 (froyo) roms. Highly recommended as an update to those running my previous 2.6.34.7 builds.

    (To those who will install on other versions of android: pre-froyo roms may have issues with camera, particular on 2708+ build or 32a boards; gingerbread can be made to work however will require a compatible vold not in gingerbread by default for USB Mass Storage;)

    Key features
    * Derived from my 20101031 build: derived from pershoots 2634 kernel with CM and other patches
    * Linux update from 2.6.34.7 to 2.6.34.8 including many Linux security updates.
    * Updated CPU governors per 2.6.35.* builds (pershoot/cm)
    * added 10MB ram (reducing camera from 16MB to 6MB) for 32a boards (both MT2.1 ebi0 kernel {patch} and classic 32a magic's ebi1 kernel {patch)
    * Some sched updates.
    * Built with gcc version 4.4.3 (via gingerbread tool chain)

    Thanks to rattking for helping me test the kernel on a MT1.2/Fender

    Known issue:

    powering down when USB attached fails [for me anyway].. AC may or may not fail.. so unplug to powerdown. (or as its your phone... don't powerdown)

    The main difference between froyo and gb (ics too) kernels is the USB stuff. If you use a froyo kernel on gb (and vice versa) USB storage won't work.

    The "power saver kernel" (which I don't have a link to) is pershoot's kernel with the USB battery drain bug fixed.

    The "power saver kernel" sources could be found at:

    https://github.com/bood/htc-magic-kernel.git

    The owner of the repository is
    bood (Bood Qian)
    Email boodweb@gmail.com
    URL http://boodweb.sinaapp.com

    He asked for the sources and patches (that could be found also in the "power saver kernel" thread)
    and started the git repository, so he is the man to contact for applying new patches, bugfixes etc.

    Enjoy.

    Just a FYI of a new build of the CM6.1/CM7 kernel:
    http://forum.cyanogenmod.com/topic/...tlies/page__pid__117678__st__5660#entry117678

    Includes anykernels for ebi0/ebi1/2708+
