This is a AOSP kernel for the lte.
since 4.2 is pretty stable I am going to start updating the changelog for it.
What is a kernel?
In computing, the kernel is the main component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components).
Sweep gestures (sweep finger across the capacitive buttons on bottom of phone):
here is a little explanation of kernel based thermal and mpdecision control
What is msm_thermal?
Kernel based 3-phase thermal control!
This replaces your /system/bin/thermald binary which is renamed by the installer to thermald_backup.
Check /sys/kernel/msm_thermal/conf/ for the thermal configuration
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)
[...]mid[...] = same as above, just for phase 2
[...]low[...] = Lowest threshold (phase 1)
check_interval_ms = how often shall we check? (sampling rate)
Default: 1000ms (=1sec)
If you want to see msm_thermal doing it's job:
Code:
adb shell cat /proc/kmsg | grep 'msm_thermal'
What is msm_mpdecision?
100% kernel based multi core decision! (should cpu1 be online or not?)
This replaces your /system/bin/mpdecision binary which is renamed by the installer to mpdecision_backup.
Check /sys/kernel/msm_mpdecision/conf/ for the configuration.
startdelay = time until mpdecision starts doing it's magic (70000)
delay = time between checks (500)
pause = if something else plugs in the cpu, fall asleep for 10000
scroff_single_core = if the screen is off, don't plug in cpu1 (1)
nwns_threshold_up = runqueue threshold, if this is reached cpu1 will be hotplugged (35)
nwns_threshold_down = runqueue threshold, if this is reached cpu1 will be unplugged (5)
twts_threshold_up = time threshold, this amount of time must have passed (250)
twts_threshold_down = same as above (250)
enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!
idle_freq = a value against that will be checked if a core +/- is requested. (486000)
If cpu0 is below that value and a core up of cpu1 is requested, nothing will happen.
If cpu1 is above that value and a core down of cpu1 is requested, nothing will happen. (otherwise it would now put down cpu1 even though it is still working)
(all times are in ms)

If you have issues with reboots viperboy has created a script to increase voltages which may help with stability for the rebellious phones thanks viperboy

Sweep2snap: with screen on: swipe left to right and press Home within 2 seconds for a screen snap
Sweep2wake: with screen off: swipe left to right to turn screen on (disabled by default for better battery life)
Phantom volume down: with screen on, touch between back and home for vol-down one notch
Phantom volume up: with screen on, touch between home and recent apps for vol-up one notch

What is FSO?
Fso has greater speed, but there is a chance of corrupting if the phone has a random reboot.
Non-fso is what a stock kernel is and does not have the corruption issue.
It's a trade off, performance for stability or visa versa
If you have issues with reboots viperboy has created a script to increase voltages which may help with stability for the rebellious phones thanks viperboy
