Default [KERNEL][04 APR] GLaDOS V2.11

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.

  • Based on stock Android kernel 3.0.8 IMM76D
  • 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 **** 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://forum.xda-developers.com/show....php?t=1138873) 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-developers.com/show....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-developers.com/show...24&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-developers.com/show....php?t=1333696) for managing the various tweaks.

  • Fixed small bug in Lazy.
  • Reduced display frequency back to stock settings.

  • Fixed a bug in LiveOC.
  • Fixed optimized compiler flags.

  • Fixed TouchWake issue of long powerkey presses causing the touch controls to be disabled without delay on next screen off.
  • For BLN the blink interval and blink time can now be adjusted in the sysfs interface. Also BLN is disabled by default.
  • For lazy the sampling rate is initialized to a default of 15000.

  • Fixed the problem of the CAM module being active all the time preventing DEEP IDLE from being used.

  • Fixed bug.
  • Removed several unnecessary kernel drivers and features.
  • Removed kernel debug and logging features.
  • Included logger as a module.

  • Fixed bugs in Live OC.

  • Fixed the freeze/reboot problems when changing the frequency limits.

  • Removed the limit of the minimum frequency to 200 when the GPU is active.
  • Preliminary bandaid to DEEP IDLE compensating for various bugs in ROMs.

  • Added Voodoo Color version 2 and Voodoo Sound version 10.

  • Update to Android kernel 3.0.8 for ICS 4.0.3 IML74K.

  • Fixed the camera problems caused by Bigmem (increases available RAM by 21MB now).

  • Added Bigmem option (increases RAM available for the system by 26MB).

  • Added DRAM scaling to Live OC.
  • Flash memory I/O tweaks.
  • Added Tiny Preemptive RCU.
  • Updated the optimized CRC32 algorithm.
  • Removed CFQ I/O scheduler.

  • Added OC frequency states 1.4GHz and 1.2GHz.

  • Fixed the problem of the touchkey backlight lighting up when touched while the screen is off.
  • Increased display frequency to 72Hz necessary to achieve 65fps.

  • Fixed the increased battery drain while in SLEEP when DEEP IDLE is enabled.
  • Fixed the problem on the NS4G of DEEP IDLE not being used while 4G is enabled.

  • Disabled most logging and debugging kernel config options.
  • Included logger and TUN as modules.
  • During installation the cache partition, Dalvik-cache and modules, init.d scripts and bootsounds from previously installed kernels are cleaned.

Stock android uses deadline scheduler or VR?

A bit off topic, but did anyone ever toy with SIO, NOOP and CFQ on Nexus S?

Default Ezekeel's own kernel?

Ezekeel's own kernel?!

I knew you have only provided kernel devs with MODs.

Very tempting... Will leave it a few releases before I jump from Matr1x but expecting this to be very good!

I'd be interested in seeing what people's battery life is like on this kernel compared to others, as that's the main selling point for me!

just ran a quadrant benchmark, ~1000 point increase from franco's 06 kernel on carbon c02 rom with 110 liveoc
