[KERNEL] [03.14.14] Beastmode DLXPUL | GCC Linaro -Ofast compiled s2w/dt2w bbm mod!

The Beastmode-DLXPUL kernel Project

Check /sys/kernel/msm_mpdecision/conf/ for the configuration.

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)
If cpu0 is below that value and a core up of another cpu is requested, nothing will happen.
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)

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.

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)

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'.

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

etc...

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

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)
