Aperture Laboratories presents​

GLaDOS V2.11​

The latest innovation in human-smartphone interaction. Our scientist have shown in extensive tests that humans operating our kernel on their devices experience 67% more joy in life while simultaneously the likelihood of being maimed or killed by falling space debris is significantly reduced. Also preliminary human trials indicate that it might offer some protection against lethal dosages of gamma radiation and blows to the head with a rod-like object.

Features:

• Based on stock Android kernel 3.0.8 IML74K
• CPUfreq governor 'lazy'
• Live OC version 1
• Custom Voltage version 1
• Battery Life eXtender (BLX) version 1
• Power saving state DEEP IDLE version 2
• Touch Wake version 1
• Backlight Dimmer (BLD) version 3
• Backlight Notification (BLN) version 9
• Brain fudge Scheduler (BFS) version 0.357
• SLQB memory allocator
• Voodoo Color version 2
• Voodoo Sound version 10
• CIFS
• TUN
• Bigmem (+20 MB more available RAM)
• USB OTG build 5

Always make a backup of your /efs/ directory (http://rootzwiki.com...backup-restore/) before installing custom kernels or ROMs.

During installation the cache partition, Dalvik-cache and modules, init.d scripts and bootsounds from previously installed kernels are cleaned.

Source code:

Do not use profiles, they are unnecessary and only lead to instabilities.

If you experience any problems and are on a nightly or kanged ROM, try the latest stable version of that ROM first. I will not give support or answer any questions if you do not try this before reporting a problem with the kernel.

If you experience stability problems like reboots, freezes, FCs and SoDs and you did OC or UV, first try changing back to the stock settings. If this solves the problems, your OC/UV configuration is not stable. There are some indications that OC/UV settings which run fine at high battery charges might still cause problems at lower battery charges. So to be safe always check that your OC/UV configuration runs fine at low battery like 5%.

I do not offer support/help/recommendations on OC/UV. If you decide to do so and your device is unstable you are on your own. Check http://forum.xda-dev...d.php?t=1335429 for help.

If you experience the problem that the DEEP IDLE state is not properly used (according to the idle_stats), read the last section of http://forum.xda-dev...324&postcount=1.

When reporting a bug always include information about your ROM and hardware model. Also be as precise as possible when describing the problem. Just because a single person is experiencing a problem, it does not mean there actually is a problem with the kernel. I always wait until at least one other person can confirm the issue before I look into it. So if you see someone posting a bug report, do not be shy and feel free to confirm the issue or if you do not have the problem let me know that too.

When asking for a feature you would like to see implemented in GLaDOS always provide a link with information about this tweak and preferably also a link to the source code.

For users unfamiliar with init.d scripts I recommend NSTools by arifhn (http://forum.xda-dev...d.php?t=1333696) for managing the various tweaks.

Very nice bootanimation and kernel Ezekeel! I've been running 1.6 for half the day now, and 1.5 for a few days prior. Very nice and snappy, I always like knowing it will be updated.

Also, welcome to RootzWiki!

Thanks.

Not much action is this forum. It is you and me and tumbleweeds...

If anyone is relying on this thread to get informed about updates please speak up, because I am seriously thinking about not updating this thread anymore because of lack of interest.

It is a bit like that sometimes, I get a bit more attention probably because I'm not at XDA for my stuff. But your thread there is going strong, so that may be why.

This kernel along with all the mods that you've put out that all dev use are phenomenal! Appreciate all your work ezekeel and certainly appreciate the speed of this great kernel! Love the 1200,1400 steps
On gingerbread I get great speed without liveoc so I can keep a good undervolte but when I use your ICS kernel I definitely liveoc at 110 because I notice a dramatic speed improvement! Can't wait for dual cores with all your mods
To many bottom feeders that don't show any appreciation! Thanks

 

[reddv1]

Hey ezekeel, any new mods up your sleeves? How about that mod i heard you mention awhile back about using the radio to help conserve battery by using the current generated by it or were you messing with us?

Anyway, love your kernel and all the mods you brought to the nexus s. People are begging their developers to port them over in other forums. Don't forget I was your first believer when you publish your BLD mod.

Just a question what's the advantages of SLQB in your kernel over the stock allocator?

Oh that radio-charge mod is still in the works. As I said on XDA, it probably will be released around 1. April next year.

Yeah. Remember that terrible first implementation of BLD that used the cron daemon to trigger it? That definitely was as example of fixing a problem with the least amount of effort. I can be really lazy.

You can get some technical info about SLQB here: http://lwn.net/Articles/311502/

It seems to perform well on systems with a small number of CPUs. I tried it and my impression was that especially the boot process was much faster and also the startup time of apps seem to have improved slightly.

Running great, thanks for sharing your work

 

[phone_user]

I'm LiveOC enthusiast

 

[nathanson666]

Thank you very much for all your work on this phone. It has really made it worth having!

 

[tehgeekguy]

1.9 is running perfect. Battery life is awesome and I haven't had a single SOD or unexpected reboot with this kernel since 1.5

 

[mattyg151]

great kernel, about to try your ICS one now

 

[Hanakuso]

Awesome mods Ezekeel. Your Nexus S kernel hacking could never be replaced.

 

[chalan30]

Thanks Ezekeel. Currently running your latest GLaDOS ICS kernel on AOSP's oICSv13 for the NS4G. Great work as always!

 

[deejaylobo]

Glados has got to be one of the best kernels for the Nexus S right now. Loving it! Thanks!

 

[gouthamsn]

Ezekeel ... Thanks for all your work posted on XDA. I love the Glados kernel. The kernel along with NSTools makes my phone a superb device. Thank you for the custom voltage, touch wake and live OC. Not just your coding, even your research into things like deep idle etc are amazing. Thanks again for your help in making our phones great.

 

[tonky]

oh man, your 1.9 kernel runs noticeably faster than franco's one, thanks!

 

[dvali]

Great kernel and a lot of original work.

 

[nmoreman]

I have switched to this kernel, currently running 1.8 after several versions and have had the best performance out of multiple
kernels from various developers possible.
All developers seem to run a variant of Ezekeel's kernels, adding his tweaks and modifications after he has researched, tested
and implemented these into his own.
He collaboration with all of these developers make an outstanding contribution to his efforts and time as a developer. I highly
recommend anyone try his kernels and know that all questions and concerns will be addressed.
