lulzactive
Free AppAbout lulzactive
Needs a custom kernel that has "lulzactive" cpu governor.
Based on "interactive" governor
Inspired by erasmux's "smartass" governor (included in Flykernel)
cpu work load >= [inc_cpu_load]%
cpu frequency changes from (Lx) to (Lx - pump_up_step)
up sampling time = 24000us (from smartass governor)
eg )
(L0)1200 - (L1)1000 - (L2)800 - (L3)500 - (L4)200
inc_cpu_load=60%, pump_up_step=1
cpu_load = 60%, current frequency = (L2)800 >> frequency = (L1)1000
cpu_load = 60%, current frequency = (L1)1000 >> frequency = (L0)1200
(L0)1200 - (L1)1000 - (L2)800 - (L3)500 - (L4)200
inc_cpu_load=50%, pump_up_step=2
cpu_load = 50%, current frequency = (L2)800 >> frequency = (L0)1200
cpu_load = 50%, current frequency = (L4)200>> frequency = (L2)800
cpu work load < [inc_cpu_load]%
cpu frequency keeps the current value or changes from (Lx) to (Lx + pump_down_step)
down sampling time = 49000us (from smartass governor)
eg )
(L0)1200 - (L1)1000 - (L2)800 - (L3)500 - (L4)200
inc_cpu_load=60%, pump_down_step=1
cpu_load = 59%, current frequency = (L2)800 >> frequency = (L3)500
cpu_load = 23%, current frequency = (L1)1000 >> frequency = (L2)800
screen off
cpu frequency is locked at scaling min freqeuncy.
default min freq of Galaxy S II is 200MHz.
you don't need to use "screen off" profile of SetCPU.
eg )
(L0)1200 - (L1)1000 - (L2)800 - (L3)500 - (L4)200
screen_off_min_step=3
(L4)200 ~ (L3)500
screen_off_min_step=1
(L4)200 ~ (L1)1000
Values
Following values are in /sys/devices/system/cpu/cpufreq/lulzactive/
inc_cpu_load: 0~100%, default is 60%
pump_up_step: 0 ~ (frequency_table_size - 2), default is 1
pump_down_step: 0 ~ (frequency_table_size - 2), default is 1
screen_off_min_step: 0 ~ (frequency_table_size - 1), default is (frequency_table_size - 2)
up_sample_time: 10,000 ~ 50,000μs, default is 24,000μs
down_sample_time: 10,000 ~ 100,000μs, default is 49,000μs
debugging
1 = print screen on/off message
2 = print governor start/stop message
4 = print frequency changing
7 = print all above (bitwise or, 1|2|4 = 7, default 1|2 = 3)
echo "7" > /sys/devices/system/cpu/cpufreq/lulzactive/debug_mode
cat /proc/kmsg | busybox grep "lulzactive"

user friendly and comes with basic instructions but a few (and random) times parameters don't stick after reboot. controlling through init.d seems more reliable. on a side note, ezterry kernel is solid stable. request: (tested) prebuilt profiles for performance, battery saving and balanced. it takes hours of experimentation and fine tuning to find the sweet spot. btw in my tablet it shows debug mode 11.

Lulzactive takes a quite a bit of tuning to get the best out of it. This makes tweaking settings fast, I can quickly test how things respond then jump back and make changes in the gui

First, I thougt it was a problem when i set on boot isn't working but it is not.. It was my fault because you must install it on internel storage not on sd card, finally its working very fine and there is no prblem anymore... BEST APP!!
