[kernel][JVQ](08/01/2011) snail kernel - aka fun with talondev, platypus scripts

captivate variant


Hi guys,

let me introduce you a "new" experimental/testing kernel:

talondev "snail" variant/edition

since I like to run my own modified & tweaked kernels on each of my devices (Linux box [-> Gentoo], SGS [-> modified Talondev & Platypus kernel])

I'm building this flavor of the Talon kernel

besides using and/or testing this kernel you're helping to test new features that might end in main Talon kernel as was the case with several of the patches now included in Talon


DISCLAIMER: the kernel (binary) and driver modules are provided as is. If problems occcur they most probably are from upstream and can be fixed with the newest version. Since I'm doing this in my free spare time as a hobby (quenching my thirst for tweaks & performance) updates will occur irregularly as time permits and I see fit (most probably when new features & bugfixes arrive). YOU are responsible for the actions that you take (such as over- or underclocking), etc. You agree that I can not be held liable for any potential damage that arises from your actions in combination with or the usage of this kernel and other related parts.

Kudos:
* Google, Andy Rubin & the whole Android crew
* Linus Torvalds & the kernel hackers for upstream Linux
* cyanogen & all the devs out there hacking on this
* Supercurio for enriching our media experience of this smartphone
* codeworkx, coolya, guiper, atinm - the whole teamhacksung|cmsgsteam crew and all other hackers working on CM7
* laststufo, hardcore, nikademus, existz, kodos96 & Ytt3r and all the other kernel hackers on the SGS forum
* zen-kernel team for inspiration to create a kernel, too
* all other contributors (devs, users, etc.) who make this possible


The purpose of these kernels is stability, features, battery runtime and performance testing with specific sticking point mentioned for each release

I could explain what Talon is but let it by explained by the master himself

(Link to TalonDev thread for the i9000: [KERNEL][JVP]TalonDEV 0.2.2R2 [OC/UV 1.6ghz][VoodooSnd v9][ZRAM][EXT4][340MB])

existz said:

Talon Kernel is an i9000 sourced 2.3 kernel for use with latest JVB Gingerbread

This kernel is still in a heavy development stage! So there may be bugs!! (hence the DEV tag)

Current Co-Devs - Kodos96, Ytt3r & zacharias.maladroit

As always, flash at your own risk, im not responsible for any damages!

* CFQ: some fixes/improvements and improved fsync performance (small files)
* nofail variants for the filesystems (less looping, cpu cycles wasted)
* mlock/mmap_sem improvements
* tweaked variants of cpufreq governors + smartass, SavagedZen, interactive, interactiveX governor + fixes (fixes memory leak)
* raised FPS cap to 65
* security: fixed kernel stack leakage
* f_mass_storage: disabled write cache support exposed to the system for faster writes
* BFQ scheduler
* some additional fixes (arm_unwind, evdev, rounding on clocksources) - where applicable
* gannet kernel module
* battery runtime improvements (testing)
* re-enabled power-saving mode on bluetooth l2cap

* enabled more IP-Tables (Firewall) and IPSec related settings
* security-affecting settings deactivated / re-enabled

This will be the last kernel for some time since I need to take care of personal things

I will still continue development on the Talon/Platypus Kernel in the background but will

keep a "small footprint" on XDA and phone-related stuff


All what you post will be read but I most likely will only answer what not already has been asked and e.g. some troubleshooting, etc.


Thanks for your understanding

I have phone-call reboot, battery 49%, SIO scheduler, ondemand governor.

thanks for the report kitkitfok !

let's see

hopefully the kernel below fixes the reboots - otherwise I'll post a kernel with default optimization flags






ok, since I'm using the kernel anyway

there's no reason NOT to share the kernel

[I love how smooth the kernel is with smartass or interactive governors ]

changes include:

- reverted to 2.6.35.7 [from 2.6.35.13 which might have led to reboots]
- aggressive + new optimization flags
- back to 2011.03 + prebuilt modem/RIL driver
- added sampling down factor to ondemand governor [please report any regressions that you encounter when using ondemand governor] [talon upstream]
- highres timer to 512 (from 250)
- security: add more randomness to mmap
- add support for high resolution timer for our platform [samsung platform]
- disabled some settings: uaccess_with_memcpy + KSM & some other I forgot
- reverted: swaptoken ck patch
- some tweaks to memory management [testing]
- some scheduler fixes & improvements that got reverted by 2.6.35.13 merge previously + one more fix
- re-added: smartass, interactive, interactiveX governors [I missed how smooth my phone was ^^]
- move to XZ instead of LZMA compression [talon upstream]
- don't remove voodoo /sbin in cleanup [talon upstream]
- set frequency lock to 100 MHz while charging [talon upstream]



if you encounter lags [don't know what exactly you mean with it - try using smartass or interactive governors - I never had luck with ondemand & experience was less smooth than e.g. with smartass ]

microlags related to swapping [short interruptions] need some more tweaking - they got way shorter than before - if they even still exist ...



if those kernels are still unstable [hopefully not]

I'll upload a kernel with stock optimization flags later




hope that this is stable and I can stay using that one for some time [approx. until October] - I have other things to do after all ...

T16 is running great for me so far! No new issues to report and not one reboot. Thanks Zacharais
