[KERNEL][NEW][4/03] XENON Kernel v1.1 [1.5ghz][Voltage Scaling][ath6kl][Partitions]
- Thread starter rohan32
- Start date
Seems to be some unnecessary kernel bloat. Really need to get rid of ISDN and all of the extra partition/file system support. There is no need for it at all on the TouchPad.
Got an SOD running on O.a.t's 3/30 build with 1 touchpad but not the other. Went to stock kernel for right now 
What I/O schedulers are available? I generally use Performance or ondemand as far as governors, but as far as I/O schedulers in AOKP M4 its either noop, cfq, or deadline. In WebOS, I have even more options consisting of noop, deadline, cfq, bfq, vr, and sio. On my phone I also have anticipatory as well. On both my phone and in WebOS, SIO with on demand seems the snappiest. Just would like to know my options.
Anyway you can open up voltage settings to be adjusted by the user? I would love to yeah this to see how far it can go.

you can install and check it out yourself.
OP's link has an uninstaller which can remove his kernel and put back the CM9 kernel if you don't like it.

I think there's a lot of extra framework that needs to go in in order for that to happen.
I could be totally off, but that's what I gathered from my impression of other phones' kernels.
(on OP)
So long as it's not their MIUI ROM (that's CM7 based, right?), I don't see why not.
per the title on that thread it's 4.0.3
I quite like this kernel. Unfortunately I can't keep it on my touchpad as I get a SOD everytime I leave my touchpad idle. =(
i have a question and hoping someone might know.
This kernel is supposed to only go up to 1.5G right? How come mine has the option to go up to 1.78G?
I looked in the original CM9 code and 1.5G is only defined to be max in the speed bins acpu_freq_tbl_nom and acpu_freq_tbl_slow. 1.78G is defined in acpu_freq_tbl_fast.
From looking at the file acpuclock-8x60.c (if I'm even looking at the correct file at all), the speed bin table is basically determined on powerup, because it will look at an efuse state, which was blown in at the factory, to determine if it's a fast silicon or slow silicon.
Can anyone confirm or deny that guess? Thanks.

Just fyi for you folks; after flashing the latest official nightly my Wi-Fi won't turn on :-(
Tried several reboots, toggled airplane mode, toggled wifi tab (goes to on position for 5 seconds then automatically turns off).
Just rebooted a final time under cyanogenmod with the stock kernel and wifi had no issues.
When it did work this kernel was awesome!

Had same issue here. Thought it was just my tp. Went to stock and got wifi back. Thanks for posting.

Did you re flash the kernel afterwards? I assume this kernel replaces the stock modules with some that were built with it, and most likely needs to be flashed again after each rom flash.

The Xenon Kernel is a project for myself to learn more about Linux and Android Kernel developing. I am a sophmore in High School and I haven't had much developing experience, so this is a learning experience. If you want to use this Kernel, you can show your support by thanking me! Right now all I need is words of encouragement and a new phone (I still have an old Symbian S60v3 phone haha). The Touchpad is my first Android device. Also, this is my second work for the Touchpad, my first is the SUPREME Modpack. I hope to make this my primary development project and improve as much as I can. Thanks for checking this out!
Download:
Instructions:
How to Install:
FIRST, MAKE A NANDROID BACKUP! This can cause serious harm to your system. I am not responsible for anything that may occur to your Touchpad, but everything should be fine.
1. Download the respective installer zip from the above link.
2. Install the zip in ClockWorkMod.
3. Wipe your dalvik-cache
4. Reboot and hope for the best!
IF YOU ARE HAVING SOD ISSUES try setting your CPU Governor to "ondemand"
How to Uninstall:
1. Restore from your backup you were supposed to make
or... if you didn't listen (shame on you... you should always make a backup)
1. Download the XENON Uninstaller from my goo-inside.me profile. This zip deletes the Xenon Kernel and adds back the default CyanogenMod 9 Kernel. It will not, however, delete the ath6kl WiFi drivers (you really don't need to unless you are having WiFi woes). To uninstall the ath6kl drivers you need to reinstall Android.
2. Install it in ClockWorkMod.
3. Wipe your dalvik-cache
4. Reboot!

*The ENTIRE CM9 team (dalingrin, verygreen/green, Dees_Troy, Flemmard, and everyone else who has contributed to this port. It is truly an honor to witness what you guys have created.1Can you add gpu oc in next build please
That's definitely high on the new features list. I hope to have another release out soon with bug fixes and probably this if I can figure out how to do it.1
