[Kernel][ICS] Devil2_0.62 [02/04/12]-BLN-Touchwake-USB_Host-LiveOC-DeepIdle2

Changelog:
03.04.2012:
no time for detailed changelog...have to sleep..

stock mem kernel has 379 mb ram
"slim" (XL) kernel comes with 390 mb
XL_BM is coming with 402 mb ram, but breaking 720p

while flashing the kernel, the modded rom files are also flashed, so you don't need to flash a new rom to get 379 or 390 mb

added new frequency: 1080 mhz (1100 does not like live_oc)

fixed SmartassV2 for live_oc (after changing live_oc value, you have to change the smartass values, too, but then they automatically apply to the live_oc value (although you can also select 800 mhz in nstools (for example)

also implemented touch recovery with custom devil menu (for some reason it takes a few seconds to load the first time)

more to come tomorrow...

[KERNELS][ICS][I9000] The ICS Kernel Benchmarking Project -Update: ICS 4.0.4

Goal of this little project is to dispel myths and hearsay and trying to assess the elusive performance of custom kernels for our beloved SGS I9000.

So far this has proven quite challenging as there is no single good benchmark on Android (yet):

• a lot of people have been misled by ridiculous Quadrant scores: ridiculous because, with some small tweaks which do not affect real performance in any way, shape or form, it is possible to boost the Quadrant score by factor 3x.
  You're free to believe that your SGS I9000 which scores 3000+ on Quadrant is faster than a SGS II, but then please leave this thread and move on.
• some kernels may seem smooth with some games, and get high scores on some synthetic benchmark, yet the UI appears "laggy" and stutters a lot in comparison to other kernels which score lower on the same benchmark
• some popular benchmarks give results with unacceptably low reproducibility, i.e. if you run them multiple times without changing a thing on your system, you get scores varying by 50% of more, in a completely random fashion
• most popular benchmarks do not measure or take into account multitasking and CPU contention with other applications, yet on a typical usage one has background tasks such as the media scanner or synchronization which kick in often and unpredictably

So this will be mostly a work in progress, i'm testing several benchmarks and several kernels in multiple combinations, trying to analyze which benchmarks offer certain criteria which make them useful, namely:

• Reproducibility of results: running the same tests multiple times, should result in a very small variance of the final score
• Performance separation: benchmarks which are too "synthetic" and show only a dependency on clock speed are not useful to discriminate "fast" kernels from "slow" kernels
• Performance representation: we all know when a kernel "looks" or "feels" fast or smooth. If a benchmarks shows you that a "laggy" kernel scores higher than a fast and responsive one, it's likely that the benchmark is not well designed

I'll work more on this thread explaining my (current) choice of tests and what they're good for.
But for now i'll just post a link to the summary table, and give a brief recommendation concerning popular ICS kernels; recommendation which i'll explain in the coming days.

Base ROM:
Slim ICS 2.8
(because is fast, smooth and has the least background stuff of all ICS ROMs which i tested)

Test Conditions:
Whenever possible, i tried to overclock the kernels to 1.2GHz which most / all phones should have no trouble achieving.
In case of Semaphore i had to use the bus / live overclock but it wasn't fully stable at 1.2GHz on my phone so i ran most of the tests at 1.14GHz.

Tested Kernels:
Stock Teamhacksung V17
Devil 1.1.6b BFS
Devil 1.1.6b CFS
Icy Glitch V14 b
Semaphore ICS 0.9.5b

Recommendation:
Devil 1.1.6b CFS, Icy Glitch V14b (with SmartassV2 and FIOPS), and Midnight ICS (with a tweaked Conservative) are trading blows for the fastest kernel.
At the time of testing, Midnight is slightly worse in terms of overclocking though, apparently due to different voltages, also it doesn't allow overclocking beyond 1.2GHz.
But what's interesting is that it achieves great performance while using a tweaked conservative governor which supposedly gives good battery life (i can't verify this claim).

Devil 1.1.6b BFS is good but obviously inferior to its CFS brother.

Semaphore has the lowest cache and memory latency in the multithreaded test, it also has impressive sd card read speed and in general appears super responsive, but it's a bit worse in 3D gaming and especially it lacks "true" overclocking, "live overclocking" changes the bus clock and is way more unstable, in fact on my phone i couldn't run it stable at 1.2GHz.

All kernels are significantly faster than the stock teamhacksung's kernel, so you have no excuses not to upgrade to one of the popular custom kernels!

ICS 4.0.4
Started testing Android ICS 4.0.4 kernels on Slim ICS 3.2.
All tested kernels are "huge mem" versions with 380+MB of available RAM, without breaking video playback or 720p recording.
Summary:

• the stock kernel from Teamhacksung is now a very respectable performer, unless you plan to overclock probably you don't need to install one of the other kernels
• Semaphore appears the smoothest, and in 3D benchmarks is scoring the highest, although by a very slim margin
• Midnight is still awesome and all around good kernel

- added vibrator intensity control (by mialwe), presets can be changend in recovery
- stock ram version now available (348 mb ram), XL (390 mb), XL_bm (402 mb)
- removed 1080 mhz freq for now
- small correction to touchwake
- small correction to selective live_oc (now the low freq really are not live_oc'ed)

to change the vibrator intensity on the fly, you have to do the following:

Ich hoffe ich darf hier schreiben.. Kurze Frage:
Ich hatte Semaphore und habe gerade Midnight geflasht.. Davon auch noch Kernel Cleaning Script benutzt.. Nun ist aber im Menü immer noch die Semaphore-App drin. Wenn ich rein gehe ist zwar nichts, aber 1. ist das normal und 2. kann ich es löschen?

[Kernel][ICS] Devil2_0.67 [13/04/12]-BLN-Touchwake-USB_Host-LiveOC-DeepIdle2
Devils Kernel von DerTeufel

Changelog:
13.04.2012:

- updated wifi driver
- user interface to switch wifi mode (pm_fast better batterie, pm_max better signal)

echo 0 > sys/module/bcmdhd/parameters/uiFastWifi (pm_fast)
echo 1 > sys/module/bcmdhd/parameters/uiFastWifi (pm_max)
​

- user interface to disable fsync (this gives more performace, at the risk of data loss on a crash, taken from ezekeel, so it should be ok

), default is off, to be safe

echo 1 > /sys/devices/virtual/misc/fsynccontrol/fsync_enabled (fsync enabled)
echo 0 > /sys/devices/virtual/misc/fsynccontrol/fsync_enabled (fsync disabled)
​

to make this settings apply after reboot, select them from recovery --> devil --> misc

- fixed voodoo color kernels (these have the VC in their names)
​

 

[Crashi]

Hat zufällig einer einen Tipp, wie man den Android OS bug mal zu leibe rücken kann? Bin etwas ratlos... das Ding hält ewig mein Handy wach. Bis zu 5 Stunden bei einer Akkuladung.
Bin aktuell auf AOKP Build 30 und Teufelkernel 0.64...
Was ist eigentlich Touchwake?

Wie kann ich mit diesem Kernel BT komplett deaktivieren, wenn ich es nie nutze? Wäre echt cool, wenn mir das mal jemand verraten würde.
