Using this kernel is at your own risk. Before flashing make backups!!!

=========================WHY====================== =========
dalingrin is now working hard at CM7 kernel, and seems nobody has post the 1.2 overclock kernel, I'v recompiled the 2.6.32.9 kernel with a few of dalingrin's patches(modified from dalingrin's git).
so for the one who wants to taste some fresh meat, here it comes~~

=========================WHAT===================== =========
http://sugwacee.dyndns.org/index.php...ml?p=/20110505
there are four versions:
1.1GHz
1.2GHz
stock 800M
BFS test version[/URL](1.1GHz)--for test only, cos it is set to very low voltages just for my NC. use it at your own risk.

1.1g version is recommended, and if your NC is a tuff one, try 1.2g

changes differ from stock 1.2 kernel(2.6.32.9):
1. freq table changed, boot 900M, and has a 1.2G/1.1G option. you can active it by using SETCPU. now let's go to youtube...
2. volume tweaks.
3. cifs and utf8 supported.
4.freq transition latency tweaks.
5. volt down.
6. ram speed tweaks, i don't know if it works or not(stock1.1->1.2 has change ram freq from 166M to 200M, and i am using a kernel which configured it as 220M, and if stable, i will post it) -- in BFS VERSION
7. BFS sched. currently i have BFS as the proc sched, all crazy(with quadrant 3D/2D improved slightly~1 fps up at DNA test, and excellent touch experience). but wifi has gone(kmod version issue maybe)[/COLOR] -- fixed, thanks to verygreen.


==========================HOW===================== =========
And of course, use CWM to flash the new kernel, just enjoy them. first boot after flashing will display an "update failed notice", turn off and then on to ignore this.
Just feel free to post feedbacks, and you can post your file:/sys/power/sr_vsel


special thanks to:
Dalingrin, for his great patches and works for NC/CM.
Verygreen, for the wlan_drv and too all the CM related works.

=======================[2011-05-13 EDIT]=============
Add BFS version.
because BFS version use a new tiwlan_drv.ko, if you change back to another kernel, do remember use NC_stock_1.2_restore_wlan_drv.zip to restore stock tiwlan_drv.ko.


===========current feedbacks============
1.1g seems to be stable for most of people. but I still doubt of it:
quadrant sometimes stop at running H.264 benchmark, I do think it has something to do with the DSP freq/volt, i have recompiled a new version to confirm this. release ASAP

thanks,,,, will give it a try,,, 1.1 g gives me a quadrant score of 1581.... the stock 800m gave me 1261,,,, big difference in how the nook feels and responds , good work...

Edit: just ran 3 more times and got 1700+ every time !

1.16GHz.
my NC will crash at 1.2G(if no volt tuned up, same as the Dalingrin' Eclair OC kernel. i prefer batterylife first,so i locked it at 1.16G, with stock volt level), fine enough, youku(sth. in China like youtube ) acts perfect.


here is the pic i post to another bbs

Excellent! Been waiting for this OC kernel. Tested 1.2Ghz (unstable) and 1.1ghz(stable) on dual boot partition running BN 1.2... it would be great to see interactive governance profile enabled and a working BT inject! It is noticeable speedier with the OC kernel.. might be replacing my Nookie Froyo with this setup.

What's the purpose for the 800M zip? To get the new features?

Any issues with wifi?
