in cpu setting > available governors.....what this is ??
smartass.
conservative.
ondemand.
userspace.
powersave.
performance.
This are the features? let your battery faster? I could spend the description of all? and which option makes the ROM faster?

smartass
Based on interactive, but better.
conservative
Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
ondemand
Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
powersave
Available in some kernels. It will keep the CPU running at the "min" set value at all times.
performance
Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking.
Don't set governor to performance just because it's "performance". It will not increase your phone's speed in any way. Better use ondemand. For performance, I suggest ondemand. For battery smartass.

Smartass is based on ondemand governor but better and not on interactive

I got reboot when I enable smartass on gingerDX, any sugession?

Few solutions
- u must not exceed the overclock limit (710 Mhz). So, change it or dint use oc
-everytime it reboots,just enter xrecovery and clear cache and dalvik cache

LDX has known problems with smartass. the only workaround is to either flash stock kernel and revert or u need to do a fullwipe

[Q] Which is the most recommended Governor

I'm using emanoN V4 with No-Frills, and since CM7.1 with SetCPU, I always used 'ondemand' as Governor.
But reading other posts on other devices forums about this, some people say SmartassV2 is the best...
So, as each device is different (specially by the ARM version and manufacturer), I decided to begin this conversation here, and listen to what people with the same device as me has to say about it.
So which Governor do you consider the best for SGM?

Im using cm7.2, setting at nofrilis Governor : SavagedZen io : sio and undervolt at cm setting, give more battery life.
Sory for bad english

Thanks for the reply, but as I can see on No-Frills, sio is th I/O Scheduler, that is already set. I'm asking here about the Governor.

Ondemand and set noop
Sent from my GT-S5570 using xda premium

on emanonV4 i use Smartassv2 nd i/o noop

I see that people are very divided between ondemand and SmartassV2.
Now with sio and noop as I/O Scheduler.
Anyone else would like to share?

i will say ondemand because cpu will be set at lowest frequency and when you need it it will set at higher frquency which will save your battery and if you want performance then no lag will be good

The principle of the ondemand governor I'd already figured out (and actually didn't like it, very rough).
I would like to hear more about the principle of the SmartassV2, whereas since this morning I'm using SmartassV2 + noop and I noticed my SGM way smoother than with ondemand + sio.
Now is wait and see if the battery is sucked more.

smartassV2 is a re-working of the original smartass governor, it allows for the CPU to scale through all frequencies from the lowest you set to the highest, based on the load occuring. Basically it scales CPU based on realtime needs of the system, saV2 supposedly incorporates some more agressive settings for screen off, and I believe quicker scaling than the original smartass.

Thanks a lot, man! And now I think that I had made my choice:
Governor: SmartassV2
I/O Scheduler: noop
Highly recommended!

Learning something about governers

What's new:-
added wheatley governor
added hotplug governor
added lionheart
added lionheartx
added Scary governor
added SavagedZen governot
Working of governers
WHEATLEY:- this is yet another governor for the users who want to save battery as much as they can
The governor intelligently set the frequencies according the usage of the CPU, if the usage is high then frequency will also be high and when usage is low it will set the low frequency
This governor is made by doing changes in the ondemand governor and can be used in the place of conservative
Click to expand...
Click to collapse
HOTPLUG:- The “hotplug” governor scales CPU frequency based on load, similar to“ondemand”. It scales up to the highest frequency when “up_threshold”is crossed and scales down one frequency at a time when “down_threshold”is crossed. Unlike those governors, target frequencies are determinedby directly accessing the CPUfreq frequency table, instead of takingsome percentage of maximum available frequency.
The key difference in the “hotplug” governor is that it will disableauxillary CPUs when the system is very idle, and enable them again oncethe system becomes busy. This is achieved by averaging load overmultiple sampling periods; if CPUs were online or offlined based on asingle sampling period then thrashing will occur
Sysfs entries exist for “hotplug_in_sampling_periods” and for“hotplug_out_sampling_periods” which determine how many consecutiveperiods get averaged to determine if auxillery CPUs should be onlined orofflined. Defaults are 5 periods and 20 periods respectively.Otherwise the standard sysfs entries you might find for “ondemand” and“conservative” governors are there.

LIONHEARTX:- LionheartX is based on Lionheart but has a few changes on the tunables and features a suspend profile based on Smartass governor.
Click to expand...
Click to collapse
LIONHEART:- Lionheart is a conservative-based governor which is based on samsung's update3 source. Tweaks comes from 1) Knzo 2) Morfic. The original idea comes from Netarchy. See here. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.

SCARY:- This is just a weird governor. It's based on Conservative which has a slower ramping than Ondemand butthen again it has Smartass elements which is a governor with one the fastest rampings.

Click to collapse
SAVAGED ZEN:- Another Smartass-based kernel with many modifications aiming to attain both better battery and performance.
Click to expand...
Click to collapse
LULZACTIVE:- This new find from Tegrak is based on Interactive & Smartass governors and is one of the favorites. When workload is greater than or equal to 60%, the governor scales up CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step. When screen is off, frequency is locked to global scaling minimum frequency.
Click to expand...
Click to collapse
INTELLIDEMAND:- Intellidemand aka Intelligent Ondemand from Faux is yet another governor that's based on ondemand. Unlike what some usersbelieve, this governor is not the replacement for OC Daemon (Having different governors for sleep and awake). The original intellidemand behaves differently according to GPU usage. When GPUis really busy (gaming, maps, benchmarking, etc) intellidemand behaves like ondemand. When GPU is 'idling' (or moderately busy), intellidemand limits max frequency to a step depending on frequencies available in your device/kernel for saving battery. This is called browsing mode.

ONDEMAND X:- governor code from latest linux (3.0 at the moment) source *plus* the suspend/wake logic. No further optimization is done.
Click to expand...
Click to collapse
ONDEMAND:- Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.

ALWAYS MAX:- The Performance “governor”, called “Always Max” on previous versions of SetCPU, allows your phone to run at maximum speed, ignoring all power saving functions.
Click to expand...
Click to collapse
SMOOTHASS:- The same as the Smartass “governor” But MUCH moreaggressive & across the board this one has a better battery life that is about a third better than stock KERNEL.
Click to expand...
Click to collapse
INTERACTIVEX:- The same thing as interactive but it clocks the cpu downto 300mhz in sleep mode.

SMARTASS V2:- Is a re-working of the original smartass governor, it allows for the CPU to scale through all frequencies from the lowest you set to the highest, based on the load occuring.

BRAZILIANWAX:- Similar to smartassV2. More aggressive ramping, so more performance, less battery.

Click to collapse
LAG FREE:- This driver is rather similar to the 'ondemand' governor both in its source code and its purpose, the difference is its optimization for better suitability in a battery powered environment. The frequencyis gracefully increased and decreased rather than jumping to 100% when speed is required.

MIN/MAX:- stays at minimum speed until more speed is needed then goes straight to highest speed.

It depends on the OC kernel if the developer included it. Are you using a custom ROM? SMARTASS V2 is the default governor of CM7 RC0 by subpsyke. :

these are the key upgrades in smartass v2 they are different from device to device
1. Smartass v2 have added a more aggressive screen off profile but if you have applied a screen off profile it will cause issue
2. Smartass v2 is more responsive than before
3. Smartass v2 have changed default frequency
4. Saves much power than before

how i configure CastagnaKernel OV for have max performance

how i configure CastagnaKernel OV for have max performance without trasform in cheese my cpu? what the governor? the i/o scheduler and the processor mhz?
Sorry for my bad english,but i am an ignorant

OV? Over-volt? do you mean OC? Overclock or UV? Undervolt
smartassV2/SIO (personal favourites)
245mhz/1800mhz (so default settings)
And I think you can better post this in the topic itself, and you will never turn your cpu into cheese, i once ran a benchmark at 2.016Ghz, and it just turned off

I remembered the cranium kernel at 2016 mhz..it became really hot...
Ondemand( little bit tweaked) 368 1804 sio...that s perfect
Q.D.E.

It would be better if you post this on kernel's thread I think there is no need to made a new post about that and sorry but and I'm not trying to be disrespectful. however you can use smartassv2 245-1800mhz that's a good choice.
Sent from my GT-I9001 using xda premium

the combination of default: lulzactive + sio is very performant (CFS version)
or you can try the governor lagfree
if you want the best reactivity using the BFS kernel version,
but is less multitasking

[Q] Min CPU freq setting for low battery consumption?

Hi!
I've found this thread which explains in detail all Governor/Schedulers characteristics and much more.
Even if the thread is SGS2 based, there is one thing that catched my attention.
It is written that setting the min CPU frequency @ 100 Mhz actually takes more power during phone standby then the 200 Mhz setting because of cpu voltages...
Does anybody has similare experiences with the Galaxy S i9000?
Which is the recommendable min CPU freq for the lowest battery consumption during Standby?
Thank you!

it depend on devices n true voltage lacking when cpu standby, but its dualcore vs single core

200MHz is the best minimum CPU frequency for both performance and battery consumption for most cases. Leave your minimum at 200MHz.
