i have setup one profile for setcpu to be like this:
"Screen off"
Max: 245760
min: 245760
(this is the lowest value selectable)
Scaling: Powersave
Priority: 100
I assume the priority being the highest the better it is selected... correct?
also on the main screen i have it set to "Conservative" and a max value of 768 and minimum of 245.
I've noticed this has made some improvements when the phone is on standby.
anybody else got any tips / tricks?
The priority is the priority of the profile, not CPU. (e.g. the screen is off, but is also charging, which one should come first)
Bear in mind that...
The lower speed - the longer time it takes to perform a task, and vice versa.
If you are running a lot of CPU-eater software, lower the clock won't help. It will just make your device choppy. And it could take more time for 'you' to play with it while the screen is on. (And the screen is the greatest juice-drinker)
So, during screen-on, the default one should be the best (2xx-9xx, on demand)
While stand-by : just keep it low. but make sure that most background software run correctly.

Use set Cpu only if u r still on 1.6 , Because Sony's 2.1 already optimises your system to run at 240mhz when not in use. So basically setcpu aint doing anything at all. untill you want it to run at higher speed , which i doubt. There is absolutely no use of setcpu anymore. Rest is upto you
I use these profiles:
Screen off - 576 max, 245 min, ondemand - Priority 70
Charging/Full - 998 max, 576 min, performance - Priority 50
Battery < 101% - 998 max, 576 min, ondemand - Priority 30
Great battery life, and great performance when the screen is on.
I m using this profile setup for SetCPU...........thanxx KEVINKILEER
Install SetCPU from the market or from the official thread :
http://forum.xda-developers.com/showthread.php?t=505419
(use Root browser and go to sdcard to install the apk)
Run SetCPU and click Autodetect Speeds. Allow Superuser.
Tick Set on boot.
Go to Profiles, tick enable / notifications.
Add profiles:
Profile 1: In call: Min 122880 , Max 787200 , Scaling conservative , Priority 100
Profile 2: Screen off: Min 122880 , Max 122880 , Scaling powersave , priority 90
Profile 3: Charging: Min 245760 , Max 825600 (set higher if you want, depends on the phone, I set it to 902400, your phone might reboot) , Scaling ondemand , Priority 80
Profile 4: Battery: 50%: Min 122880 , Max 787200 , Scaling conservative , priority 70 (remove this profile if you care more about performance)
Profile 5: Battery: 101%: Min 122880 Max 806400 (set higher for more performance and less battery life) , Scaling ondemand (set to conservative if you want to save more battery) , priority 60
(Set min CPU speed to 245mhz to fix wake up lag, uses more battery however.)
Add different/more profiles if you want, these are the ones I use.
Its great app to control the speed and battery as well, been using this too and it helps a lot.
I've teste CPU Control lite to change the CPU Min frequency and Governor in my Galaxy Player 5, but the app fails to tell what's the previous setting.
Can anybody tell me the default Min Frequency and governor?
The default Governor is called Lazy and im not too sure about the min frequency but I think it may be 600mhz
When I use setcpu, it reports that the cpu can go all the way to 100mhz under lazy scaling.
CPU scaling app. maybe it would help with battery life if we had the option to scale down the cpu

Here I've gathered some info for newcomers to the Android world.I've tried to keep it relatively simple. So if you want more info Comment Below
Recommended apps for manipulating kernel values:
1. Kernel Adiutor (Free to change governor and tune variables)
2. Kernel Adiutor-Mod (Free to change governor and tune variables)
3. Compatible kernel managers (e.g Stweaks, Synapse, UKM, etc.)

block_down_multiplier_hotplug x -> block down multiplier for core x
block_up_multiplier_hotplug x -> block up multiplier for core x
sampling_down_max_momentum -> max sampling down factor which should be set by momentum (0 disable momentum, possible range from sampling_down_factor up to MAX_SAMPLING_DOWN_FACTOR, default 0 disabled)
sampling_down_momentum_sensitivity -> how fast the sampling down factor should be switched (possible values from 1 to 500, default 50)
sampling_down_factor -> depending on which mode is active the factor for sampling rate multiplier which influences the whole sampling rate or the value for stock 'down skip' functionality which influences only the down scaling mechanism (possible values are from 1 to MAX_SMPLING_DOWN_FACTOR, default 1 disabled)
freq_limit_sleep-> limit freqency at early suspend (possible values 0 disable limit, 200-1600, default: 0)
freq_limit -> limit freqency at awake (possible values 0 disable limit, 200-1600, default: 0)
scaling_proportional -> if enabled load-proportional frequencies will be calculated in parallel and will be used in decision for next freq step. after a comparison between normal system table step and proportional step the lowest of these two frequencies will be used for next freq step in both directions. (0 to disable, any value above 0 to enable)
scaling_block_temp -> CPU temperature threshold from where governors freq 'holding' should start. if the given temperature (if CPU temp reading is enabled) is reached the frequency used in tunable 'scaling_block_freq' will be forced targeted and scaling stays on this freq till the temperature is under the threshold again. at the same time hotplugging up work is blocked so in this throttling phase offline cores are staying offline even if the hotplug up thresholds are reached (0 to disable, values between 30 and 80 in °C)
scaling_up_block_cycles -> similar to scaling fastdown but here for a slowdown of up scaling
scaling_up_block_freq -> similar to scaling fastdown but here for a slowdown of up scaling

disable_hotplug -> switch to enable/disable hotplugging (possible values are any value above 0 to disable hotplugging and 0 to enable it, default 0)
auto_adjust_freq_thresholds -> if enabled all freq thresholds used by the governor will be adjusted accordingly to the new scaling max policy. in particular the thresholds will be increased/decreased by the actual changed max freq step if that change will undercut/exceed the actual min/max freq policy it will stop at the max possible frequency step before undercutting/exceeding min/max freq policy (0 to disable, any value above 0 to enable)
early_demand -> switch to enable/disable early demand functionality (possible values 0 disable or 1 enable, default: 0)
grad_up_threshold -> scale up frequency if the load goes up in one step of grad up value (possible range from 1 to 100, default 50) little example for understanding: when the load rises up in one big 50% step then the frequency will be scaled up immediately instead of wating till up_threshold is reached.
early_demand_sleep -> same function as early demand on awake but in addition combined with fast scaling and sampling rate switch and only active at sleep. (possible values 0 disable or 1 enable, default is 1)
grad_up_threshold_sleep -> 2 way functionality: early demand sleep grad up (load gradient) threshold and at the same time load threshold for switching internally (tuneables are staying at set values!) sampling_rate_sleep_multiplier to 2 and fast_scaling to 2 (possible values from 1 to 100, default is 35)

sampling_rate_current -> read only and shows currently active sampling rate
sampling_rate_idle -> sampling rate which should be used at 'idle times' (possible values are any sampling rate > 'min_sampling_rate', 0 to disable whole function, default is 0)
sampling_rate_idle_delay -> delay in cycles for switching from idle to normal sampling rate and vice versa (possible values are any value and 0 to disable delay, default is 0)
sampling_rate_idle_threshold -> threshold under which idle sampling rate should be active (possible values 1 to 100, 0 to disable function, default is 0)
scaling_block_cycles -> amount of gradients which should be counted (if block threshold is set) and at the same time up scaling should be blocked and after that a forced down scaling should happen (possible values are any value, 0 to disable that function, default is 0)
scaling_block_freq -> frequency at and above the blocking should be active (possible values are any possible scaling freq, 0 to enable blocking permanently at every frequency, default is 0)
scaling_block_threshold -> gradient (min value) of load in both directions (up/down) to count-up cycles (possible value are 1 to 100, 0 to disable gradient counting)
scaling_block_force_down -> multiplier for the maximal amount of forced down scaling cycles (force down cycles = block_cycles * force_down) therefore the forced down scaling duration (possible value are 2 to any value, 0 to disable forced down scaling and use only scaling up blocks)
profile_number -> switches profile (possible value depends on amount of profiles in cpufreq_zzmoove_profiles.h file, please check this file for further details!) 0 = tunable mode, default 0)
scaling_fastdown_freq -> will be enabled once this frequency has been met or exceeded (0 to disable, all possible system frequencies, default is 0)
scaling_fastdown_up_threshold -> once the above frequency threshold has been met, this will become the new up_threshold until we fall below the scaling_fastdown_freq again. (range from over fastdown_down_threshold to 100, default is 95)
scaling_fastdown_down_threshold -> once the above frequency threshold has been met, this will become the new down_threshold until we fall below the scaling_fastdown_freq again. (range from 11 to under fastdown_up_threshold, default is 90)
scaling_responsiveness_freq -> will be enabled once this frequency has been met or exceeded (0 to disable, all possible system frequencies, default is 0)
scaling_responsiveness_up_threshold -> the up_threshold that will take effect if scaling_responsiveness_freq is set (range from 11 to 100, default is 30)
hotplug_engage_freq -> will not bring any cores online until this frequency is met or exceeded

music_max_freq -> maximum frequency for CPU when governor is on music mode
music_min_cores -> minimum CPU cores used when governor is on music mode
music_min_freq -> minimum frequency for CPU when governor is on music mode
afs_threshold 1,2,3 -> Auto fast scaling for step one to three respectively (range from 1 to 100)

[ PARAMETERS ]
Quote:
boost_duration - how long you want the governor to boost your CPU in seconds.
down_rate - The minimum amount of time in nsecs to spend at a frequency before we can ramp down. Notice we ignore this when we are above the ideal frequency.
io_is_busy - Consider if IO is busy
max_cpu_load - CPU freq will be increased if measured load > max_cpu_load
min_cpu_load - CPU freq will be decreased if measured load < min_cpu_load
ramp_up_during_boost - should ramp_up steps during boost be possible
ramp_up_step - Frequency delta when ramping up above the ideal frequency. Zero disables and causes to always jump straight to max frequency. When below the ideal freqeuncy we always ramp up to the ideal freq.
Touch_poke_freq - Also known as the touch boost frequency. This is the frequency that you CPU jumps to when touching screen.
Hotplug tunables
--------------------------
Mako Hotplug:
Quote:
load_threshold: system load threshold to decide when online or offline cores from 0 to 100
high_load_counter: counter to filter online/offline calls. The load needs to be above load_threshold X high_load_counter times for the cores to go online otherwise they stay offline
max_load_counter: max number of samples counters allowed to be counted. The higher thevalue the longer it will take the driver to offline cores after a period of high and continuous load
cpufreq_unplug_limit: if the current CPU freq is above this limit don't offline the cores for a couple of extra samples
min_time_cpu_online: minimum time in seconds that a core stays online to avoid too many online/offline calls
int timer: sample timer in seconds. The default value of 1 equals to 10 samples every second. The higher the value the less samples per second it runs
msm_mpdecision/bricked hotplug
Quote:
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.
max_cpus = max cpus to be online (if you set it to 2 and min_cpus to 1 you will basically have a dualcore)
idle_freq = a value against that will be checked if a core +/- is requested.
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)
AutoSMP
Quote:
max_cpus, min_cpus, scroff_single_core, delay: Look at description above
enabled: Enable/Disable AutoSMP. Y ( for enabled). N (for disabled)
cpufreq_down: Percentage values for downrate limit (range from 0 - 100)
cpufreq_up: Percentage values for uprate limits (range from 0 - 100)
