    CM7 & MIUI only

    NEO series

    (since May 24th '11)

    Do you want to discuss on this kernel, get the news on the current state of development, or test kernels even fresher than fresh ?

    connect via webchat from your browser:

    QuakeNet Web IRC (qwebirc)
    and join #platypus-kernel

    Fire up your IRC client, and join via client
    the server (for now is) : irc.quakenet.org
    port : 6667
    Channel : #platypus-kernel

    (thanks to Tk for the layout idea :p)

    before you ask for any ETAs:

    The first rule of CyanogenMod [and this project]: DO NOT ASK FOR AN ETA!

    First step before install & kernel switch:

    Always have this cleaning script on your internal SD card ready

    If you're switching kernels, have issues with auto-rotation, the cam, bootloops or other sorts of problem (failed overclock attempt),
    please use lippol94's updated cleaning script (apply via CWM recovery)

    Hi guys,

    this is my first modded kernel for the SGS (CM7/MIUI only)

    I first needed to test it to make sure that it'll be stable & boot at the first place

    so far it's very fast & responsive & smooth

    This thread shall serve as the center for my testing kernels (stability & functionality-wise)

    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.

    * 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 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 extensive stability testing addressing the following sticking points:
    - overall stability & functioning of the kernel and phone
    - call drops, missed calls, etc.
    - lags (suggestions for improvements are welcome)
    - auto-rotation, sensors, etc.
    - Voodoo Control Plus [any crashes ? compatibility problems ?]
    - working on CM7 or MIUI ?
    - scheduler, sound, video synchronisation & lags: Tap Tap Revenge 4 (especially at the beginning of songs)
    - scheduler, sound, video synchronisation and any other issues: doodle dash (while shooting & sound activated)
    - proper pmem memory layout & settings: proper functioning of Google Googles

    FAQ / Q&A

    @bootloop / boot post victims ^^

    Hi guys,

    could you please try to replace the existing kernel on your MIUI or CM7 nightly CWM-Package with my kernel, modules and its scripts ?

    then install that updated package (with the new kernel, modules and scripts)

    after that all should work

    the bootloops seem to be an issue with bml_over_mtd (broken sectors on the SSD on your phone)

    I'll investigate this and see if anything needs to be rewritten and/or updated in that regard

    Thanks !

    Overclocking / Undervolting:

    Q: I'm new in OC/OV operations so please could you explain to me how to set it in the best way?
    A: start with -50 mV (delta from default value) other values probably are too low

    my testing includes:

    - Angry Birds Rio (several missions)
    - Gun Bros (for some time)
    - mp3 playback, (flac playback - optional)
    - surfing the web via browser, opening up bit.ly links from cmsgsteam twitter feed
    - watching youtube video
    - watching video via rockplayer lite or mobo video player
    - running benchmarks (Smartbench 2011, quadrant standard, an3dbenchXL, anTutuBench)
    - Labyrinth Lite (for gravity sensor), auto-rotation (also for sensor)

    when 1 GHz (1,2 or 1,3) is OK - go lower with undervolt value (e.g. -75 mV)
    after it gets un-stable - go back to last known stable value

    then you can limit max frequency to lower one, e.g. 800 MHz

    and repeat testing for that frequency

    LED Support FAQ

    Q: Do LED notification require an app, such as BLN, etc ?
    A: No. It uses Android's and Cyanogen settings, other apps are not required, although some that are designed for regular LEDs may work.

    Q: How to I turn off LED notifications, scheduled or/and complete turn off?
    A: Use Cyanogen's Quiet Hours feature (settings>cyanogen>sound>quiet hours) and check "Dim the LEDs during quiet hours" (in reality it will turn them off on the SGS). If you schedule a complete day, then LED notifications will be off all the time.

    Q: How do I setup per app, find other LED settings etc?
    A: Settings>cyanogen>interface>LED notifications

    Q: What to do with LED color settings?
    A: We have only one color, so that doesn't work. Use Green as default setting. Some non-bright colors turn off notification, as it's the equivalent as diming LEDs (note that on real LEDs if you dim them too much they look like off too anyway, the difference is that it's gradual. On the SGS the LEDs can be only on or off, not gradual)

    Q: How can I troubleshot my system, I can use ADB but...
    A: adb logcat | grep lights (on linux) will show you Android requests to turn LED on or off. "status" tells you what we decide will be interpreted as "turn LED on" (1= on, 0 = off)
    adb shell cat /proc/kmsg for live view (or adb shell dmesg if you're using adb after the issues occurs - careful the backlog is limited in size so don't be too slow)
    notify_led_on and notify_led_off are requests to the kernel to turn LED on or off.
    touch key write/read errors (cypress) are non-fatal failures to ask the touch key to do something (eg lit up the LED), when the hardware goes crazy or there's a logical error in the code (can be both)
    touch key recovery routine or "stopped responding" are either hardware errors, either a logical error where the driver would try to write something the touchkey doesnt understand. in some occasion lock&unlock fix those as a work around, of course a permanent fix is required

    Voodoo Color settings:

    Q: I don't have that nice ice-ish white color on my screen anymore - you suck !

    Q: my screen looks like someone pissed on the screen - you suck !

    (sorry for the language ^^)

    A: I love you too ^^
    download Voodoo Control or Voodoo Control Plus

    Screen RGB multipliers:

    - Red: 321*
    - Green: 321*
    - Blue: 429*

    Screen v1 gamma hack:

    - use Alt. settings

    - or if you prefer others - use: "Reset to 2.3.3 defaults", "Punchy settings" (punchy could lead to a great screen while locking the screen and having "screen off" animation disabled)

    other recommended settings:

    Android OS bug, :

    (thanks to ceriko ! and his awesome guide for DarkyROM 10.1)

    If your battery drains very fast and your battery stats mentions Android OS above 10%, often between 40 and 60%, sometimes more, this is the best to do as far as I know:

    - Remove the 2/3 system files as per the beginning part of this guideguide about batterie issues.
    - Install WatchDog and open (I set it to "moderate", then I close it, that's all), this app will warn you whenever an app or a process miss-behaves by draining the battery excessively. It will not fix it but just flag it and you will see a notification.
    - Reboot usually stops the drain for a while until it naturally comes back, so reboot whenever you see Android OS above 10% and rising or after you see WatchDog mentioning "Suspend" process using too much battery (the suspend process hanging is the Android OS bug).
    - Some apps trigger it, most common are Gameloft games (blame Samsung, not the games/apps). No need to use apps or games for this drain to happen, it also happens straight after boot once phone has been fully charged.

    This bug can not be fixed by anyone but Samsung. Some never see it, some will experience it everyday no matters what they do... It's just annoying and unfair but that's the same on all Gingerbread releases by Samsung (JVK, JVB, JVO, JVH). Apparently even the SGS2 has this...

    screenstate scaling aka my governor won't change after screen locked:

    take 90screenstate_scaling from the kernel-package

    and modifiy / edit:




    for ondemand governor



    for smartass governor

    then put it back in again in the kernel-package

    (or: system/etc/init.d)

    best would be:

    - reboot into Recovery
    - Advanced -> fix permissions (in Clockworkmod Recovery)
    - reboot

    Also mit dem "ondemand" Kernel habe ich eine viel bessere Akkulaufzeit unter CM7 erreicht. Jetzt hält mein SGS ungefähr 3 mal so lange und komme locker über den Tag (und das bei meiner Nutzung).

    Echt toller Kernel!

    Mit stock kernel funzt alles einwandfrei.

    ok danke, berichtest du dann bitte, wenn es Probleme geben sollte ? danke !

    @hermz, domy1985:

    was für ein Netzwerk (GSM/UMTS) und Modem verwendet ihr bitte ?

    welche Programme laufen bei euch im Hintergrund ?

    tritt das auch auf, wenn ihr nicht das neuste nightly-update verwendet ?

    ich hab mal eine Test-Batterie an modifizierten Kerneln vorbereitet:

    1) der neue GSM (only ?) Fix wird nur deaktiviert

    2) Wechsel nur auf Ondemand governor

    3) alte conservative governor Einstellungen

    4) ondemand governor mit Änderungen der schnellen Timings und (vermutlich) freundlichere Scheduler-Einstellungen

    5) conservative governor mit Änderungen der schnellen Timings und (vermutlich) freundlichere Scheduler-Einstellungen

    Jeder adressiert genau eines oder mehrere Probleme

    1) reboot beim Telefonieren

    2-5) klobiges Verhalten

    6) Toolchain ? <-- wenn alles oben nicht hilft, liegt es an der Toolchain

    Download Link <--

    das solltet eigentlich ihr mir sagen :lol:

    versuch es mal mit dem 1.

    der wird Probleme mit Reboots beim Telefonieren beheben,

    die anderen Probleme werd ich mit neueren Test-Kerneln lösen können

    ich brauch aber zunächst mehr Feedback

    also, mit kernel #1 hatte ich gestern nacht noch einige freezes im ADW-launcher, sowohl im appdrawer als auch einfach am homescreen, ohne jegliches zutun....
    phone.apk hat sich heute nach ca. 3min telefonieren auch wieder aufghängt, softtasten haben noch reagiert, aber kein output am screen; anschließend reboot.

    flash jetzt wieder mal a samsung-rom, bin etwas genervt von cm7 im moment...
    ich komm dann wieder wenns die ersten RC's gibt - oder wenn mir samsung am ar*** geht :D


    edit: so ein mist, als könnt ich nach cm7 jemals wieder auf einer samsung rom arbeiten -.-
    tschüss samsung, hallo zurück cm7! :D

    EDIT: auch #2 führt bei tel-gesprächen >2min zu freeze&reboot, test heut mal #5...
