    *** ON-THE-FLY-RAMDISK EDITS!

    *** THIS KERNEL USES YOUR RAMDISK, it will just modify it on the fly while flashing. These changes are not creating any incompatibilities with roms/other kernels.
    * removes min freq overrides from the ramdisk
    * removes governor overrides from the ramdisk
    * adds init.d support to your ramdisk (if not already supported)
    * modifies stock ondemand settings
    * add module insertion

    [size=14]Und hier noch einige weitere sehr spezifische Informationen:[/SIZE]

    [size=12]Was ist msm-Thermal[/SIZE]

    Spoiler anzeigen


    [FONT=Verdana]Kernel based 3-phase thermal control!
    This replaces your /system/bin/thermald binary which is renamed by the installer to thermald_bck.
    It will throttle your cpu speed to keep it cool and unleash it if the cpu has cooled down enough. (3 phases: low, mid and high)[/FONT]

    [FONT=Verdana]Check /sys/kernel/msm_thermal/conf/ for the thermal configuration [/FONT]

    [FONT=Verdana]allowed_max_high = highest threshold (phase 3)
    allowed_max_low = remove the throttling if we cooled down to this (clr_thrshold)
    allowed_max_freq = max frequency if throttled (limit)[/FONT]

    [FONT=Verdana][...]mid[...] = same as above, just for phase 2
    [...]low[...] = Lowest threshold (phase 1)[/FONT]

    [FONT=Verdana]check_interval_ms = how often shall we check? (sampling rate)[/FONT]

    [FONT=Verdana]shutdown_temp = if we reach this shut down the device![/FONT]

    [FONT=Verdana]If you want to see msm_thermal doing it's job:
    Code:
    adb shell cat /proc/kmsg | grep 'thermal' [/FONT]


    [size=12]Was ist msm-mpdecision?[/SIZE]

    Spoiler anzeigen


    [FONT=Verdana]100% kernel based multi core decision! (should cpu1/2/3 be online or not?)
    This replaces your /system/bin/mpdecision binary which is renamed by the installer to mpdecision_bck.[/FONT]

    [FONT=Verdana]Check /sys/kernel/msm_mpdecision/conf/ for the configuration.[/FONT]

    [FONT=Verdana]startdelay = time until mpdecision starts doing it's magic (20000)
    delay = time between checks (70)
    pause = if something else plugs in the cpu, fall asleep for 10000ms (10 secs)
    scroff_single_core = if the screen is off, don't plug in cpu1/2/3. Additionally: Unplug all cpus except cpu0 when screen is turned off (1)
    enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!
    min_cpus = min cpus to be online, cannot be < 1. Default: 1
    max_cpus = max cpus to be online, cannot be > 4. (if you set it to 2 and min_cpus to 1 you will basically have a dualcore) Default: 4
    idle_freq = a value against that will be checked if a core +/- is requested. (486000)
    [size=10]If cpu0 is below that value and a core up of another cpu is requested, nothing will happen.[/SIZE][/FONT]
    [size=10][FONT=Verdana]If any other cpu is above that value and a core down of that cpu is requested, nothing will happen. (otherwise it would now put down that cpu even though it is still working, which isn't what we want)[/FONT][/SIZE]

    [FONT=Verdana]Hot plug thresholds (aka now it gets 'complicated')
    This small formula calculates which value will be used: (number_of_cpus_online - 1) * 2
    The result of this formula will be the nwns_threshold where a new cpu is hotplugged.
    The result of this formula + 1 will be the nwns_threshold where a cpu is unplugged.[/FONT]

    [FONT=Verdana]nwns_threshold_x = runqueue threshold, if this is reached cpuX will be hot/unplugged
    twts_threshold_x = time threshold, this amount of time must have passed for the related action to be taken (hot/unplug)[/FONT]

    [FONT=Verdana]Example:
    One cpu is online.
    (1 - 1) * 2 = 0 ergo:
    nwns_threshold_0 = cpu1 will be hotplugged at this value
    ((1 - 1) * 2) + 1 = 1
    nwns_threshold_1 = cpu0 will be unplugged at this value
    Since we can't unplug cpu0 this is '0'.[/FONT]

    [FONT=Verdana]Two cpus are online.
    (2 - 1) * 2 = 2 ergo:
    nwns_threshold_2 = cpu2 will be hotplugged at this value
    ((2 - 1) * 2) + 1 = 3
    nwns_threshold_3 = cpu1 will be unplugged at this value[/FONT]

    [FONT=Verdana]etc...[/FONT]

    [FONT=Verdana]The default values are:
    NwNs_Threshold: 12, 0, 25, 20, 32, 28, 0, 35
    TwTs_Threshold: 140, 0, 140, 190, 140, 190, 0, 190
    Where the position and function of the number equals the result of the above explained formula.[/FONT]

    [FONT=Verdana](all times are in ms)
    If you want to see the mpdecision magic happening:
    Code:
    adb shell cat /proc/kmsg | grep 'MPDEC' [/FONT]

    [size=12]Mpdesicions "input even boost" aka Project Butter[/SIZE]

    Spoiler anzeigen


    [FONT=Verdana]his will boost your min cpu speed if you touch the screen or press a button and gives you full control.
    In those events the min cpu freq will be risen to a predefined value (look below) on every online cpu. This boosts overall reaction times and smoothness a lot. (works similar to the qcom mpdecision binary)
    Configuration files:
    root@android:/sys/kernel/msm_mpdecision/conf # ls | grep boost
    boost_enabled
    boost_freqs
    boost_time[/FONT]

    [FONT=Verdana]All of them work like the usual sysfs files, except one special case:
    boost_freqs will list all frequencies from cpu 0 to cpu x. Cpu 3 and any following cpu will share one frequency.
    To change those frequencies echo the cpu number + the frequency in khz.
    Example: To change the boost freq of cpu3 (and 4,5,6,7,8, etc) the echo would look as follows:
    Code:
    echo "3 960000" > /sys/kernel/msm_mpdecision/conf/boost_freqs
    for cpu0:
    Code:
    echo "0 960000" > /sys/kernel/msm_mpdecision/conf/boost_freqs
    Defaults:
    Code:
    cat /sys/kernel/msm_mpdecision/conf/boost_freqs 960000 960000 729600 576000 [/FONT]

    [size=14][COLOR=red]Warum habe ich kein WLAN mehr?[/COLOR][/SIZE]

    Spoiler anzeigen


    [FONT=Verdana]Due to this kernels very high optimization settings it is too big for our boot.img with WLAN included into the kernel, so it is built as a module. That means it needs to be inserted into the kernel upon boot up, which needs to be automated for maximum comfort.[/FONT]

    [FONT=Verdana]The zip adds module insertion to your ramdisk, if that fails for some reason the wlan module cannot be inserted.[/FONT]

    [FONT=Verdana]if
    Code:
    adb shell lsmod
    doesn't show this:
    Code:
    tun 14701 0 - Live 0x00000000 cifs 275399 0 - Live 0x00000000 bcmdhd 2964650 0 - Live 0x00000000 (C)
    Then something went horribly wrong.
    Chances are that I broke it and this should never happen.
    One post in the issue tracker will probably fix it with the next release [/FONT]

    [FONT=Verdana]You can restore wlan for your current bootup by executing:
    Code:
    adb shell su insmod /system/lib/modules/bcmdhd.ko [/FONT]


    [size=12]Gibt es eine App zum optimalen einstellen der Kernel-Features?[/SIZE]

    Ja, die App heißt KControl ---> PlayStore

    -----[INDENT][COLOR=red][size=18]What is sweep2wake?[/SIZE][/COLOR][INDENT][youtube]APR6iR3QnBc[/youtube]
    Disabled as default, activate through an app like KControl or over sysfs: echo 1 > /sys/android_touch/sweep2wake
    [/INDENT][COLOR=red][size=18]What is doubletap2wake / knock knock?[/SIZE][/COLOR][INDENT][youtube]S2Q3hRSSRak[/youtube]
    Disabled as default, activate through an appapp like KControl or over sysfs: echo 1 > /sys/android_touch/doubletap2wake
