Notes/Issues/User guide:

• The absolute stable version is 188v4, please consider anything above as a beta.
• Use smartmax for daily/battery and gaming for performance/gaming.
• If you want extra battery, and you are ready to give up smoothness for it, then use "pmc" governor, more info here.
• If you want even more performance then you can use interactive or ondemand with gaming boost.
• If you have hiccups in music, use interactive there too.
• If too much heat generated during games, cap your CPU to 1-1.2GHz, the performance difference will be minimal, also a safe undervolt (25-50mV) should help a lot.
• About UV: CPU VDD should be close to Core VDD, by default there is a 100-300mV(depending on kernel) lock between them. Core minimal voltage is 950 at default. This means even if you set 100mV to any freq, it won't go below 650-850. And this also means, if you UV your GPU, while you have CPU UV, CPU UV that seemed stable can become unstable.
  So if you plan on UVing GPU, you should UV that first, and CPU only after that.
• I'm not responsible for any damage, this kernel might cause.
• Thanks to pabx, maxwen, n3ocort3x, tbalden, kozmikkick, showp1984,TripNRaVeR and everyone who contributed to this kernel.
• There might be a 1sec delay after wake one sense roms, before the screen processes touches. It's a S2W thing, if you don't want it, disable S2W.(See below)
• Here is an awesome guide about how to get the maximum out of your phone, both in battery and performance

Auto-BLN Issues:

• Green led might stuck after removing from charger if there is an unseen notification. Just check the notification to solve.
• Green led might not come up after a finished charge.
• BLN will not work while charging the phone.

AOSP Installation:

1. Repack!
2. Install modules from recovery (Install the zip)
3. Wipe dalvik cache. Yes, it's important, the versions could have some binary level differencies (from different compiler options) which can lead to unknown behaviour with old dalvik code.
4. Erase fastboot cache
5. Flash kernel image with fastboot

Sense Installation:

5. If you have problems with some functions not working on your ROM, then repack. Otherwise it's not needed.

Configuring kernel parameters:

S2W Configs:
Turn off:

Code:

echo "0" > /sys/android_touch/sweep2wake

Or you can download "Sweep2Wake-Widget" from Google Play.
Button panel locks to s2w after this distance:

Code:

/sys/android_touch/s2w_register_threshold

Screen turns on/off after this distance:

Code:

/sys/android_touch/s2w_min_distance

Direction independent(1 - Yes, 0 - No):

Code:

/sys/android_touch/s2w_allow_stroke

DoubleTap2Wake Configs:
Turn on:

Code:

echo "1" > /sys/android_touch/s2w_allow_double_tap

Activate fast charge:

Code:

echo '1' > /sys/devices/platform/htc_battery/fast_charge

Enable smartdimmer:

Code:

echo "1" > /sys/devices/tegradc.0/smartdimmer/enable

To get your variant:

Code:

cat /sys/kernel/debug/t3_variant

(Or see it in a root explorer)
cpu_process_id is your variant.

3D Tuning:
If you want to change clocks, you have to write the whole clock table again, from up to down. In case you want to reset to default, this is it:

Code:

echo '520 520 520 520 492 484 380 247' > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc

If you want to set them at boot, use an init script. Here is one. Just copy to /system/etc/init.d and set the permissions to executable by everyone with a root explorer. (Thx to Byrana)
Here is a flashable script that will work on newer kernels too for everyone. It also enables fast_charge. (Thx again Byrana)

2D Tuning:
If you want to change clocks, you have to write the whole clock table again, from up to down. In case you want to reset to default, this is it:

Code:

echo '520 520 520 520 492 484 380 247' > /sys/devices/system/cpu/cpu0/cpufreq/two_d_oc

You should NOT OC this higher than 3D.

EMC Tuning:
If you want to change clocks, you have to write the whole clock table again, from up to down. In case you want to reset to default, this is it:

Code:

echo '667 667 667 667 408 408 408 408' > /sys/devices/system/cpu/cpu0/cpufreq/emc_oc

If you want to OC let's say to 800MHz:

Code:

echo '800 800 800 800 667 667 408 408' > /sys/devices/system/cpu/cpu0/cpufreq/emc_oc

Auto-BLN Control:
Interface:
/sys/class/leds/button-backlight/auto_bln
Values:

• 0: BLN OFF/Green led ON
• 1: BLN ON/Green led ON
• 2: BLN ON/Green led OFF

Example:
Turn off Auto-BLN:

Code:

echo '0' > /sys/class/leds/button-backlight/auto_bln

The changes will apply from the next notification.

Backlight button brightness:
Interface:
/sys/class/leds/button-backlight/button_brightness
Values:

• 0-255: 0 is off, 255 is the maximum possible.

Example:

Code:

echo '50' > /sys/class/leds/button-backlight/button_brightness

The changes will apply from the next backlight turn on.

GPU Voltage control:
If you want to enable this you should write '1' to /sys/devices/system/cpu/cpu0/cpufreq/gpu_voltage.
In command line that is:

1. Code:

   echo '1' > /sys/devices/system/cpu/cpu0/cpufreq/gpu_voltage

2. After that you need to restart your voltage control app (Trickster Mod).
3. Now you will see the GPU frequencies multipled by 1000 to separate them from the CPU frequencies. So you will see 520000MHz, etc.

Be advised that there are a really few HOX's that can handle more UV on Core, than the preset 50.
Also incrasing your Core voltage over 1300mV is NOT ADVISED AT ALL. Almost everything uses this voltage on your motherboard.
If you want to enable the values at boot, you need an init script that enables it, so later Trickster mod or anything can set them.

LP OC:
Interface:
/sys/module/cpu_tegra/parameters/enable_lp_oc
Values:

• 0: LP OC OFF
• 1: LP OC to 620MHz

Example:
Turn on LP OC:

Code:

echo '1' > /sys/module/cpu_tegra/parameters/enable_lp_oc

Audio Min. Freq.:
Interface:
/sys/module/snd_soc_tlv320aic3008/parameters/audio_min_freq
Example:
Change audio min. freq. to 204MHz:

Code:

echo 204000 > /sys/module/snd_soc_tlv320aic3008/parameters/audio_min_freq

Save settings:
If you want any of the above settings saved, you can use iba21's recovery package.
