[kernel/rom] cm9/ics build with fixes [02/09/2012 flash.zip update or full rom]

---

[ 02/09/2012: Screen Flicker / Brightness is an issue. I'll be looking at it. ]

Hi guys,

In an attempt to help further kernel development for the Kindle Fire, I'd like to share my stock defconfig. It's a bit different than the original otter_android_defconfig that g1011999 came up with.

I was never able to get a usable kernel. So I took some time and built up mine.

https://github.com/KFire-Android/ker...roid_defconfig

This kernel builds using the preferred TI compiler used in all of their walk-thrus: CodeSourcery 2010-q1

Moving forward into CM9/ICS, some changes need to happen to the kernel over time. The migration kernel is found in a branch: "L27.13.1-ICS". The END result of this will be a kernel / source that fully support hw codecs for ICS.

[02/08/2012] FLASH ZIP FOR THOSE RUNNING NIND'S BUILDS: http://bit.ly/xYOf0V

The following ROM is built from the sources at GitHub under the KFire-Android org. Many of those files and configurations are the result of countless hours of development by JackpotClavin. I don't want there to be any confusion as to who put in a ton of time getting this to work.

[02/09/2012] FULL ROM INSTALL: http://bit.ly/ygVvQB

Changelog:
- Screen flicker IS an issue right now. Digging into it
- Touchscreen "Slop" set to 16. This should help touches register on the touchscreen.
- Working Data usage stats (xt_qtaguid / xt_quota2 kernel modules)
- TUN, CIFS support
- USB mounting fixes

Thanks Hashcode, currently building a latest ICS version of it.

A little note for those who also want to compile: arm-eabi-4.4.3 and arm-eabi-4.4.0 did not work for me, they ended the compile without any errormessage in the middle of nowhere, arm-eabi-4.3.1 did the job. Took me some time to figure that out ...

If you want to follow a very good step by step guide for setting this up the same way TI (the CPU maker) intended, then follow this:

Obviously, that's for PandaBoard, but the Toolchain source and setup are very good.

It goes into deep sleep for me and turning off the stay awake option in settings, developer options, the screen goes off like its supposed to.

Tonight, I'll go back to both of my in-progress kernels and do some testing to see if they'll boot.

EDIT:
Current issues being looked at with this kernel:
- Power off doesn't really power all the way down. It goes to a black screen, but requires long press to turn off.
- Deep sleep isn't happening. The backlight is on a tad while the screen should be off.

But this config is still MUCH better than trying the original.

So does this boot cm7 or anything? My kernel builds boot stock kindle but not cm7

Its something to do with netd/dnsproxyd. Just finding a fix that works is a PITA common issue, but then people dont say how they fixed it..

Right now ive only tested this with CM9

Any chance you're looking into enabling more than 2 touch points in this kernel?

I'm running nind/sitic's cm9-02-04 build with this kernel baked in. I, too, have Stay Awake disabled in Developer Options, and my Kindle is going into deep sleep. I am experiencing the power down issue, though.

It's something I'm absolutely willing to live with for the time being. This is good stuff. Thanks Hashcode!

Thats really the future of this kernel. I needed a solid base to start from.

Well reason I asked was because my kernel wont boot cm7 or cm9. It boots the stock kindle fire os okay. Im getting netd/dnsproxyd errors in the kernel when I try booting cm7.
