[KERNEL][CM10.1] BigMem + OC - Huawei MediaPad, T-Mobile SpringBoard

UPDATED 6.06
Changes:
- Linux 3.0.80
- Allow more undervoltage
- GPU overclock
- OC to 1.7
- early suspend/late resume drivers
======
As we known, mediapad's camera is very poor and useless, I never use the camera except the front camera for skype.
So I've been thinking to trade the back camera function with more available RAM.
Then I decided to build my own kernel from cm10.1 kernel, do a liitle changes then recompile it...
my changes is just editing these lines:
Code:
#define MSM_PMEM_SF_SIZE 0x0000000
#define MSM_PMEM_ADSP_SIZE 0x1000000
It works ... my total ram jumped from about 710MBto 870MB ... thats about 160MB (20%) addition
And the surprise is the camera and video playback still works flawlessly...
I've been using this kernel for 2 days now without single crash and no known bugs so far.
The battery is also good... the performance should be great too because I use gcc 4.7 from the ndk to compile it
I don't know how to do the github thing and my connection is too slow to do that, so... I just share it here:
here is the new kernel:
DOWNLOAD
Tested on CM10.1 by after_silence
just download n then
Code:
fastboot flash boot boot-6.06.img

simply rename the bigmem image to boot.img and inject it to OC kernel flashable zip by after_silence then you can install it from twrp. no need adb or fastboot again.

Hi
Sounds interesting. Could we get more information?
Are bugs known? Is something missing? Is this kernel OC capable?
What did you do to free up do much Space?
Thank you for developing. Will try it later this day.

Tried installing it via TWRP and get a 'Error installing bigmem.zip' or something like this.
Maybe it's just me.

that's not flashable zip... you should flash it with fastboot
no, this is not oc-capable yet
--
EDIT: This is already OC-able now

---

I want more info too

manteb bero... :thumbup: :thumbup:
OC is the must for mediapad. hope you will release it soon

Thank you for your work!
It is really fast. Don't know, if it is because of more RAM or because of compiling with NDK, but I checked the speed with Antutu and the score is 2000 Points above the one with after_silence's kernel (both OCd to 1674mhz) and 300 above comec's ICS.

Will check it now, but no bugs found yet.
Edit: It is not undervoltable below 800mV. Would be nice to have the lower voltages, like in after_silence's kernel.

after's kernel can go down to 750mV...I would like to have same range here anyway excellent work

---

Can this kernel use in every cm10.1 rom?
or Only last cm 10.1 rom, Thank you.

---

Hi everybody, this kernel is really good, fast and stable on overclock (I run at 1620) but I've found some problems with undervolting... I use IncrediControl and even one step down in undervolting (down to 800 in the lower frequencies) on the causes reboots and system crashes... Don't know if someone else has noticed this but by now do not undervolt this kernel.

github

Works for me at 800mV. No crash or reboot yet.
Just mentioned at github, that sharonsym is working on the OC-Section.
Maybe it works for you in the next release.

I tried it and it runs very unstable, it reboots immediately after boot (lockscreen appears for a second)

uv can goes downto 750mV now
