[KERNEL][CM7][Froyo] Dalingrin's OC kernel w/fixed IO perf (quadrant) & 1.2Ghz test
Disclaimer: As always, flash at your own risk.
So, recently there has been alot of debate over why quadrant (and to some extent, system performance) was lower with the OC kernel, as compared to the stock CM7 kernel. (http://forum.xda-developers.com/show....php?t=1002504
) As part of my examining the problem, i went looking for a solution. Starting from the first OC CM7 kernel, i would run quadrant and see how the performance fared. I finally found the issue appeared in the 3-08a kernel; using that, i rolled back changes until i found the commit remove to fix the issue. Specifically, it seems to be somewhere in the 22.214.171.124 update: https://github.com/dalingrin/nook_ke...ingerbread-exp
In short, using his source, i have compiled a kernel with fixed I/O performance, and all his other tweaks (interactive gov, etc).
So, I want to make this clear; this is still dalingrin's kernel; in no way do i wish to take credit for his work. But, while he is out, work must go on, right?
Who is this kernel for?
eMMC Froyo and CM7 users
Will this work on SD cards?
It may if you manually replace you uImage, but i cannot guarantee it (since i cannot test it)
Is everything working in this release?
everything like bluetooth and dsp should still be just fine (you may have to do a few hard shutdowns/reboots to kick on BT, like normal).

[b] For those having problems setting this speed in the CM7 performance settings, give setCPU a try, but don't use profiles. Using set CPU, i am able to get my system stable at 1190, where the CM7 manager instantly locks up.
After flashing, please make note of OVERALL system response. The dip in quadrant scores prompted the fix, but i feel that the system is overall better; I would like some more input if others are seeing this as well.
Any and all feedback is welcome, and I will do what i can for support...
