I've been staring at BatteryStatus' CPU Scaling function wondering what good it does if I use it... and how do I use it if I decide that it was useful. I'm sure some users here are wondering the same thing, especially on our low-powered Wizards. Can someone lay it thick for us CPU-shy users?
The CPU Scaling function in BatteryStatus Pro adjusts CPU speed automatically according to CPU usage, so you can get faster speed when using application, ans saves power when you are waiting (i.e. loading a web page).
The rate of scaling is fully adjustable (max speed, min speed, step, threshold, step interval)

Awesome! Something usable when my phone's bluetooth connected to my car.
Now, how does one set up these options to take advantage of this function?
It'd be better if you search "battery status" (only titles) here..You will come across the battery status development thread, which has all the info you need, plus it points to the home page for the app which also has a manual..
Dont get me wrong but pls search before shooting off questions.

Well said !
Dont get me wrong but pls search before shooting off questions.
Plz read the forum,you'll find all the answers to your question in here,these kind of questions have been asked hundreds of times in various threads or shud have posted in the appropriate thread from you downloaded your present rom TNT 5.0. Or hit the 'Search' button at the top with your specific word to locate,you'll be amazed.There's no need to start a new thread for this.
Just remember...
More Mhz translates into less power efficency.
ie.
195 mhz (stock speed) = Regular Baterry consuption
240 mhz (overclocked speed) = Over Regular Baterry consuption
260 mhz (overclocked speed) = High Baterry consuption
280 mhz (overclocked speed) = you got the idea
Also remember that when increasing the processor Speed may cause your system to hang or not wakeup if you are using a very low frequency.
Best regards.
hello guys so i was looking at this project for Motorola Droid X:
http://code.google.com/p/milestone-overclock/
since Droid X has similar OMAP3630 chipset i thought we could try it out for this device...
if it has already been tried out by u guys then sorry for dupe post
anyways the sources available (milestone-overclock-module-1.4.8.tar.gz) were not directly compatible with the i9003 kernel sources (GB_CHN_UPDATE1) so i have modified it slightly.... and now the module gets compiled and it gets loaded (by insmod)... the sysfs and proc interface is active... even the app (MilestoneOverclock148.apk) detects the module correctly... but the changes dont work...
i invite all devs to help out with this...
modified sources are posted here:
https://github.com/DooMLoRD/i9003-overclock
noobs kindly dont spam this thread....
P.S.: Droid X has got overclock upto 1.4GHz with help of this so i am sure we can try little more overclock than 1.1GHz
If you look at the Samsung code in arch/arm/mach-omap2 and /plat-omap, and compare it with code seen for example in the nook color sources (OMAP 3630, see here), there are HUGE differences.
Normally the opp frequency table seems to be hard coded and easy to edit. Samsung on the other hand decided to dynamically assemble it in board-latona.c with info from cpufreq34xx.c (if I overlook that correctly). These differences could be the reason the module does not work.
Further, the line Amit and you changed in clock.c could - but I am not quite sure - actually lead to 10% higher clocks on every opp step. Because what you changed
Code:
- mpurate *= 1000000;
+ mpurate *= 1100000;
is a conversion factor from MHz to Hz. The line
Code:
if (mpurate < 1000)
above seems to be a logical check if the desired clock has been given in Hz or MHz, which is expected to be at max 800 for the 3630. For our 3640 the highest frequency is 1000, which would require the check to be
Code:
if (mpurate < 1001)
or similar, but they might have overlooked this change. If the input is below this boundary, it is thought to be in MHz, and is converted to match the internal logic which works with Hz only.
And two more questions: I experimented a lot with the OC code, and even added two new opps (1100/840 and 1200/865) to my tables. I could select them, and everything including cpufreq scaling tables was correct, but the CPU never was actually clocked above 1000MHz. Do you know why? And did you check if it is with your kernel (compare benchmark values, do not trust any other source, they all lie )?
previously i was also having milestone A853 and by the overclock module it can be overclocked to 1.2 ghz

Yes I know the changes in diff omap kernel sources... Spent a few hrs today comparing milestone/droid x and i9003 kernel sources to get this module complied and loading...
I am sure that the change done by amit is correct, because there is a very prominent change in linpack scores ~18 compared to ~16 which is typical of a 10% overclock...
As for ur other two questions I posted this earlier in the other thread
DooMLoRD said:
Not sure... These omap chips seem to have only 4 bins (300/600/800/1000)... We are currently making the 1000 MHz bin run at 1100mhz... I am not sure if we can add extra bins... I tried adding a lower 125MHz bin, it was shown by setcpu but the device never really went below 300mhz... May be we need to investigate it further...

OK, so the overclock is working. Nice Concerning the mpurate, have a look here. The author is working at TI, so I expect him to be familiar with the code. However, that does not mean we can't use the conversion factor for overclock. It's just not "clean".

And another idea: For the Nook Color, there is a guy who implemented an interface and an app to change the clocks. It is different from droid-overclock, because he implemented a sysfs interface in the kernel sources. Hope this helps.

That looks very much like the sysfs interface we added for VDD control on QSD8250/MSM7X30... Should work I think...

I made progress with the sysfs interface seen on the Nook. Kernel boots, and the correct rates are displayed under /sys/power/mpu_freq_oppX. I was also able to set the hightest opp to 800 MHz, so that the two highest were both at the same frequency. The setting worked (confirmed with Linpack). But 1100 MHz was ignored (stayed at 1000). Looking into this further.

so wht cpu freq table are u using exactly?
wht i think is we should concentrate on this (atleast for now):
just keep the 4 bins as is (300, 600, 800, 1000)
then try n get the access to these via sysfs (or proc)
see if we can modify them via that interface, say change 1000 to 1100 or change 800 to 900
and then do tests if these work...
if possible make a sysfs (or proc) interface for VDD (voltage control) too...
have u pushed the testing changes... i am working on same thing here... might help to speed things up...
I am currently testing on the master branch, so the branch is "wrong", but this is the commit:
Sysfs interface
Because only underclock works as of now, I am tested setting
Code:
if (mpurate < 2000)
but that didn't help. Now I will define 1100 and 1200 MHz steps in board-latona.c and cpufreq34xx.c to see if this helps.
EDIT: Nope, that didn't solve it. CPU does not run at 1100. Not even 900. Stays at 1000 in both cases. 800 can be forced...
some updates on the overclock module:
we need to search in /proc/kallsyms for:
clk_init_cpufreq_table
cpufreq_stats_update
on our kernel (uc-kernel v04) they are at:
Code:
c005a198 T clk_init_cpufreq_table
c03c5aec t cpufreq_stats_update
these may be different on stock kernel we need to use specific address
I just thought this might be helpful since Optimus black has the same hardware.

Why these two? Cpufreq seems to be quite happy with the frequency tables. All frequencies are correctly listed, and the highest available for hardware and scaling are correct (say 1100, if I set it). But some "mysterious barrier" doesn't let the cpu clock as high as requested by cpufreq.

Looked into it, and got the module to load and change frequencies by manually setting omap2_clk_init_cpufreq_table_addr=0xXXXXXX. I was able to underclock to 800 and back to 1000 MHz. 1200 was set, but not correctly applied - the mpu was still running at 1000 MHz. Further on, it ****ed up the frequency table. Instead of [300,600,800,1000] it was [600, 600, 1000, 1000] after the test. Not good

yups code needs some more patching but i am sure this is the way forward for stable overclock
I've got the basics working with a completely reworked sysfs interface (no module). See GitHub.
The idea is simple: At all times, there shall be no more than 4 OPPs enabled. For each overclock "wish", we disable the currently highest OPP, and enable the overclocked one. If this has no corresponding OPP yet, we create it.
The code works, and has the following problems / features:
Only the highest OPP can be set for now. Consequently, the overclock has to be higher than 800 MHz.
The voltage is not adjusted, yet. All overclock frequencies are run with the 1 GHz stock voltage.
The cpufreq table, policy and stats are not updated, yet
The cpu does not go into deep sleep after the clocks have been adjusted (possibly because the cpufreq table is wrong)
As OPPs are added to the table if necessary, it is theoretically possible to max out the OPP array by defining new frequencies hundreds of times (depending on the maximum array size).
To set the frequency (in MHz), type
Code:
echo "1100" > /sys/power/overclock_max_freq
It would be really cool if you could take a look, DooMLoRD. The only real problem I see right now is the cpufreq table. If this would be correctly updated, the rest would be "easy" I tried some stuff (not in the commit), but nothing worked, yet.

this is the same problem as with other overclocks i was playing with...
the cpufreq table doesnt get updated... only the module based way seems to change that table...
anyways we will have to investigate this further...

Nice. Hehe
Welcome to Smurf Land.......Where you are whisked away to a smurfalicious place!
LA LA lalalala LA LA LA LA LAAAAAA....
Alright enough with the cuteness of all this.
Basically I have created a script that prompts you (the user) to answer some vital information them based on your answers the script will inject specific tweaks to your build.prop and also to a file in your init.d folder. These tweaks include battery tweaks, memory tweaks, speed tweaks, governor tweaks, 3g and wifi tweaks, SD card tweaks, and a bunch of random tweaks. Some collected from a bunch of different phones tweaks and others created by me.
The script will search out every line in your build.prop and remove any line that is there that I am adding and remove it first to reduce duplicate codes. It will remove a whole list of other init.d files that conflict with it. Will also create a few other files and folders to add functionality and speed optimization to your phone.
What if you do not like the tweaks that I added.....well the script creates back-ups for you and you can choose the option to Un-Smurf and it will set you back to before you installed.

Please feel free to post a thread in other forums or other site but please link back to here for the downloads. I am trying to give the user the best experience possible and if dl links are made all over the place then there is possibility for them to not get updated when I release a new version. Plus the info in the first three post here explains alot.
Developers
If you would like this baked into your ROM the PM me and I can help. I already have a ZIP file created with he exact files that you need and instructions with how to implement. I need to make a few corrections based on your specific Rom but it is an easy fix and would rather do it or help you do it so there arnt any conflicts at all. I have already helped a few other DEV's bake it into their Roms and it works great.
Thank Me
If You Find this post USEFULL and ENJOY using the SMURFED OUT Script then Please take the time out to THANK ME. I'm Not asking for Donations but this does take countless hours to put together. Also you can click the links in my sig to see my working in the google market(PLAY) follow me on my Twitter and Facebook sites
Info
I/O Scheduler descriptions
Different Governors
LMK Settings (Low Memory Killer)/ADJ & MINFREE Values
ICS USERS
IF running ICS then go here to auto patch your SERVICE.JAR for new OOM settings.
FYI your services.jar can be found /system/frameworks/services.jar.
Seriously
If your coming from a version before 4.0 I Highly recommend Un-Smurfing First
Highly Recommended
If you want to make sure the settings stick....go into your /system/etc/init.d folder with script manager and set the 45smurfed file to run as root and run at boot. Some say this makes the setting stick others see no effect.
MUST READ
If your launcher does not show up in the auto detector then please inform me of the package name (found in /data/data) usually looks like this blah.blah.launcher. I will add it to the database and update the script rather quickly.
Change log

Added Instant Smurf-Power option which will clear out caches and give your phone an oh so fresh feeling (kinda like restarting your phone without having to)
Added in half a dozen build.prop tweaks
Fixed Some issues with the 45smurfed file
Added in ability to choose how much you want your Dalvik heapsize to be
Rearranged the Loopy Smoothness Tweak
Added in EXT4 Tweaks (convert your sd card over to ext4 and answer the question in the script for it to go into effect)
Added in swap support
Added in some new checks
Added in some permission sets so settings dont get overwritten
I'm sure there are more but can't think of any
Highly recommended that you UN-SMURF before you run the newest version as some of the files that the script removed in last version are needed in this version.

Fixed wifi and 3g not switching, addition of last minute build.prop tweak jacked it all up
V 6.5
Fixed some syntax errors
Corrected names of a few launchers

Tried to fix Launcher Detector not reading some Launchers but cant get pm list packages to sent list to a file with out getting a segmentation error...any suggestions would be helpful
If your launcher is not found and you know the name of it try it out cause its saved in the detector as a launcher just isn't being autodetected
On AOKP and roms based off of it some of the init.d tweaks you find in rom control startup tweaks will not work anymore as i removed them becuase my script does it for you now. They will be restored if you Un-Smurf

V 4.0
Removed some tweaks that were causing issues
Added in some new tweaks
Changed a few Settings for better response
Script now checks to see if your using a local.prop and if so copies settings to it as well

Comments put into script to explain what exactly is going on
Credits given in OP

Over 30 build.prop edits with more to come.
For a detailed list of settings that this script copies to your Build.prop go to /sdcard/SmurfedBackups/Smurfed_Out.html
!!! WARNING !!!
This Script now interferes with alot of other scripts. I'd recommend unsupercharging and removing some other scripts as well...Tweaks, Read Ahead SD card tweaks, Governor Tweaks, and I'm sure there are a few others. This script searches for some of the scripts mentioned and removers them if found.
Un-SMURF
During the Smurfing process a copy of all removed files is sent the the SmurfedBackups folder on your SD card. When un-smurfing your phone will be restored back to the exact way before Smurfing.
Future Releases
1. Adds in as many battery saving, speed, and responsiveness tweaks as I can find throught out many different forums.
2. removes any other script that is previously installed that may be using same tweaks....if not removing the script itself it will search out each line of each script and remove the lines individually.
FEEDBACK & BUG REPORTS
Please leave feedback after you run so others know how well this script works. I will try my best to help with any bugs that are found. If found please report in this thread with the following info
What Rom are you running?
What Phone are you using?
What settings did you choose in Smurfed Out script?
What Governor are you running?
What kernel are you using?
What things did you try before reporting?
What issues are you running into?
What is your Name and Social Security number? (lol)
What is your Blood Type? (LMAO)
Have you ever thought about donating an organ? (LMFAO)
Syntax Errors or Suggestions
If reporting syntax errors or suggestions to improve the script then please put them into code brackets so I can easily read them and also line number if you happen to remember helps as the script is over 2500 lines now. I appreciate all help with these errors and suggestions to improve the script.
Troubleshooting
My WiFi or 3G doesn't work or wont switch?
Go into recovery and wipe dalvik-cache and cache and reboot.
Check to see if data is enabled in your settings.
Check to make sure if your using a battery saver app like battery xl or juice defender that is not turning off your radios
My camcorder isn't working?
Make sure your using the most recent script. The fix was made available on V 4.1
Does this script work for other phones?
Yes in theory it does. Let me know if it works or not and I'll put it in the OP so others know
I can't get this script to run in script manager?
Make sure you are opening the script with superuser rights within script manager
Can I run this in terminal emulator?
yes type this is command line. also make sure that Smurfed Out is on root of your sd card
Code:
su
sh /sdcard/Smurfed_Out.sh
After running the script and rebooting Im getting a blank black screen?
First scroll down and read just in case and follow those instructions then follow Bug Reporting procedures
My phone got up and ran away from me?
Well this can be a problem....On one hand that would mean that this script really works...on the other hand it means your just not cool enough for you phone anymore and it found someone better.
Just In Case
Build.prop.zip attached is a flashable zip in case of emergency. It has the build.prop of aokp rom in it. If your not running that rom...download the zip. open it up. go into the system folder. Replace the build.prop with the build.prop from the Rom.zip that you are running. Put on your sd card. Flash in recovery. I am putting this here cause in the past there were issues with the script causing a freeze after boot and some people had to nand back or reflash their rom. This will fix that. Enjoy.
[SCRIPT] Smurfed Out V 5.0 (ultimate build.prop/init.d tweaks) Updated 3-18
I/O Scheduler Descriptions
Taken from this post here
Q. "What purposes does an i/o scheduler serve?"
A.
Minimize hard disk seek latency.
Prioritize I/O requests from processes.
Allocate disk bandwidth for running processes.
Guarantee that certain requests will be served before a deadline.
So in the simplest of simplest form: Kernel controls the disk access using I/O Scheduler.
Q. "What goals every I/O scheduler tries to balance?"
A.
Fairness (let every process have its share of the access to disk)
Performance (try to serve requests close to current disk head position first, because seeking there is fastest)
Real-time (guarantee that a request is serviced in a given time)
Q. "Description, advantages, disadvantages of each I/O Scheduler?"
A.
1) Noop
Inserts all the incoming I/O requests to a First In First Out queue and implements request merging. Best used with storage devices that does not depend on mechanical movement to access data (yes, like our flash drives). Advantage here is that flash drives does not require reordering of multiple I/O requests unlike in normal hard drives.
Advantages:
Serves I/O requests with least number of cpu cycles. (Battery friendly?)
Best for flash drives since there is no seeking penalty.
Good throughput on db systems.
Disadvantages:
Reduction in number of cpu cycles used is proportional to drop in performance.
2) Deadline
Goal is to minimize I/O latency or starvation of a request. The same is achieved by round robin policy to be fair among multiple I/O requests. Five queues are aggressively used to reorder incoming requests.
Advantages:
Nearly a real time scheduler.
Excels in reducing latency of any given single I/O.
Best scheduler for database access and queries.
Bandwidth requirement of a process - what percentage of CPU it needs, is easily calculated.
Like noop, a good scheduler for solid state/flash drives.
Disadvantages:
When system is overloaded, set of processes that may miss deadline is largely unpredictable.
3) CFQ
Completely Fair Queuing scheduler maintains a scalable per-process I/O queue and attempts to distribute the available I/O bandwidth equally among all I/O requests. Each per-process queue contains synchronous requests from processes. Time slice allocated for each queue depends on the priority of the 'parent' process. V2 of CFQ has some fixes which solves process' i/o starvation and some small backward seeks in the hope of improving responsiveness.
Advantages:
Considered to deliver a balanced i/o performance.
Easiest to tune.
Excels on multiprocessor systems.
Best database system performance after deadline.
Disadvantages:
Some users report media scanning takes longest to complete using CFQ. This could be because of the property that since the bandwidth is equally distributed to all i/o operations during boot-up, media scanning is not given any special priority.
Jitter (worst-case-delay) exhibited can sometimes be high, because of the number of tasks competing for the disk.
4) BFQ
Instead of time slices allocation by CFQ, BFQ assigns budgets. Disk is granted to an active process until it's budget (number of sectors) expires. BFQ assigns high budgets to non-read tasks. Budget assigned to a process varies over time as a function of it's behavior.
Advantages:
Believed to be very good for usb data transfer rate.
Believed to be the best scheduler for HD video recording and video streaming. (because of less jitter as compared to CFQ and others)
Considered an accurate i/o scheduler.
Achieves about 30% more throughput than CFQ on most workloads.
Disadvantages:
Not the best scheduler for benchmarking.
Higher budget assigned to a process can affect interactivity and increased latency.
5) SIO
Simple I/O scheduler aims to keep minimum overhead to achieve low latency to serve I/O requests. No priority quesues concepts, but only basic merging. Sio is a mix between noop & deadline. No reordering or sorting of requests.
Advantages:
Simple, so reliable.
Minimized starvation of requests.
Disadvantages:
Slow random-read speeds on flash drives, compared to other schedulers.
Sequential-read speeds on flash drives also not so good.
6) V(R)
Unlike other schedulers, synchronous and asynchronous requests are not treated separately, instead a deadline is imposed for fairness. The next request to be served is based on it's distance from last request.
Advantages:
May be best for benchmarking because at the peak of it's 'form' VR performs best.
Disadvantages:
Performance fluctuation results in below-average performance at times.
Least reliable/most unstable.
7) Anticipatory
Based on two facts
i) Disk seeks are really slow.
ii) Write operations can happen whenever, but there is always some process waiting for read operation.
So anticipatory prioritize read operations over write. It anticipates synchronous read operations.
Advantages:
Read requests from processes are never starved.
As good as noop for read-performance on flash drives.
Disadvantages:
'Guess works' might not be always reliable.
Reduced write-performance on high performance disks.
Q. "Best I/O Scheduler?"
A.There is nothing called "best" i/o scheduler. Depending on your usage environment and tasks/apps been run, use different schedulers. That's the best i can suggest.
However, considering the overall performance, battery, reliability and low latency, it is believed that
SIO > Noop > Deadline > VR > BFQ > CFQ, given all schedulers are tweaked and the storage used is a flash device
Explanation of Different Governors
Pulled from this page here
1) Ondemand:
Default governor in almost all stock kernels. One main goal of the ondemand governor is to switch to max frequency as soon as there is a CPU activity detected to ensure the responsiveness of the system. (You can change this behavior using smooth scaling parameters, refer Siyah tweaks at the end of 3rd post.) Effectively, it uses the CPU busy time as the answer to "how critical is performance right now" question. So Ondemand jumps to maximum frequency when CPU is busy and decreases the frequency gradually when CPU is less loaded/apporaching idle. Even though many of us consider this a reliable governor, it falls short on battery saving and performance on default settings. One potential reason for ondemand governor being not very power efficient is that the governor decide the next target frequency by instant requirement during sampling interval. The instant requirement can response quickly to workload change, but it does not usually reflect workload real CPU usage requirement in a small longer time and it possibly causes frequently change between highest and lowest frequency.
2) Ondemandx:
Basically an ondemand with suspend/wake profiles. This governor is supposed to be a battery friendly ondemand. When screen is off, max frequency is capped at 500 mhz. Even though ondemand is the default governor in many kernel and is considered safe/stable, the support for ondemand/ondemandX depends on CPU capability to do fast frequency switching which are very low latency frequency transitions. I have read somewhere that the performance of ondemand/ondemandx were significantly varying for different i/o schedulers. This is not true for most of the other governors. I personally feel ondemand/ondemandx goes best with SIO I/O scheduler.
3) Conservative:
A slower Ondemand which scales up slowly to save battery. The conservative governor is based on the ondemand governor. It functions like the Ondemand governor by dynamically adjusting frequencies based on processor utilization. However, the conservative governor increases and decreases CPU speed more gradually. Simply put, this governor increases the frequency step by step on CPU load and jumps to lowest frequency on CPU idle. Conservative governor aims to dynamically adjust the CPU frequency to current utilization, without jumping to max frequency. The sampling_down_factor value acts as a negative multiplier of sampling_rate to reduce the frequency that the scheduler samples the CPU utilization. For example, if sampling_rate equal to 20,000 and sampling_down_factor is 2, the governor samples the CPU utilization every 40,000 microseconds.
4) Interactive:
Can be considered a faster ondemand. So more snappier, less battery. Interactive is designed for latency-sensitive, interactive workloads. Instead of sampling at every interval like ondemand, it determines how to scale up when CPU comes out of idle. The governor has the following advantages: 1) More consistent ramping, because existing governors do their CPU load sampling in a workqueue context, but interactive governor does this in a timer context, which gives more consistent CPU load sampling. 2) Higher priority for CPU frequency increase, thus giving the remaining tasks the CPU performance benefit, unlike existing governors which schedule ramp-up work to occur after your performance starved tasks have completed. Interactive It's an intelligent Ondemand because of stability optimizations. Why??
Sampling the CPU load every X ms (like Ondemand) can lead to under-powering the CPU for X ms, leading to dropped frames, stuttering UI, etc. Instead of sampling the CPU at a specified rate, the interactive governor will check whether to scale the CPU frequency up soon after coming out of idle. When the CPU comes out of idle, a timer is configured to fire within 1-2 ticks. If the CPU is very busy between exiting idle and when the timer fires, then we assume the CPU is underpowered and ramp to max frequency.
5) Interactivex:
This is an Interactive governor with a wake profile. More battery friendly than interactive.
6) Lulzactive:
This new find from Tegrak is based on Interactive & Smartass governors and is one of the favorites.
Old Version: 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.
New Version: Three more user configurable parameters: inc_cpu_load, pump_up_step, pump_down_step. Unlike older version, this one gives more control for the user. We can set the threshold at which governor decides to scale up/down. We can also set number of frequency steps to be skipped while polling up and down.
When workload greater than or equal to inc_cpu_load, governor scales CPU pump_up_step steps up. When workload is less than inc_cpu_load, governor scales CPU down pump_down_step steps down.
Example:
Consider
inc_cpu_load=70
pump_up_step=2
pump_down_step=1
If current frequency=200, Every up_sampling_time Us if cpu load >= 70%, cpu is scaled up 2 steps - to 800.
If current frequency =1200, Every down_sampling_time Us if cpu load < 70%, cpu is scaled down 1 step - to 1000.
7) Smartass:
Result of Erasmux rewriting the complete code of interactive governor. Main goal is to optimize battery life without comprising performance. Still, not as battery friendly as smartassV2 since screen-on minimum frequency is greater than frequencies used during screen-off. Smartass would jump up to highest frequency too often as well.
8) SmartassV2:
Version 2 of the original smartass governor from Erasmux. Another favorite for many a people. The governor aim for an "ideal frequency", and ramp up more aggressively towards this freq and less aggressive after. It uses different ideal frequencies for screen on and screen off, namely awake_ideal_freq and sleep_ideal_freq. This governor scales down CPU very fast (to hit sleep_ideal_freq soon) while screen is off and scales up rapidly to awake_ideal_freq (500 mhz for GS2 by default) when screen is on. There's no upper limit for frequency while screen is off (unlike Smartass). So the entire frequency range is available for the governor to use during screen-on and screen-off state. The motto of this governor is a balance between performance and battery.
9) Intellidemand:
Intellidemand aka Intelligent Ondemand from Faux is yet another governor that's based on ondemand. Unlike what some users believe, 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 GPU is 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. We can see some 'traces' of interactive governor here. Frequency scale-up decision is made based on idling time of CPU. Lower idling time (<20%) causes CPU to scale-up from current frequency. Frequency scale-down happens at steps=5% of max frequency. (This parameter is tunable only in conservative, among the popular governors )
To sum up, this is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling, and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such. Intellidemand does not jump to highest frequency when screen is off.
10) Lazy:
This governor from Ezekeel is basically an ondemand with an additional parameter min_time_state to specify the minimum time CPU stays on a frequency before scaling up/down. The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand. Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state on a step overriding sampling interval. Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always select the maximum frequency while the screen is off.
11) Lagfree:
Lagfree is similar to ondemand. Main difference is it's optimization to become more battery friendly. Frequency is gracefully decreased and increased, unlike ondemand which jumps to 100% too often. Lagfree does not skip any frequency step while scaling up or down. Remember that if there's a requirement for sudden burst of power, lagfree can not satisfy that since it has to raise cpu through each higher frequency step from current. Some users report that video playback using lagfree stutters a little.
12) 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.
To 'experience' Lionheart using conservative, try these tweaks:
sampling_rate:10000 or 20000 or 50000, whichever you feel is safer. (transition latency of the CPU is something below 10ms/10,000uS hence using 10,000 might not be safe).
up_threshold:60
down_threshold:30
freq_step:5
Lionheart goes well with deadline i/o scheduler. When it comes to smoothness (not considering battery drain), a tuned conservative delivers more as compared to a tuned ondemand.
13) LionheartX
LionheartX is based on Lionheart but has a few changes on the tunables and features a suspend profile based on Smartass governor.
14) Brazilianwax:
Similar to smartassV2. More aggressive ramping, so more performance, less battery.
15) SavagedZen:
Another smartassV2 based governor. Achieves good balance between performance & battery as compared to brazilianwax.
16) Userspace:
Instead of automatically determining frequencies, lets user set frequencies.
17) Powersave:
Locks max frequency to min frequency. Can not be used as a screen-on or even screen-off (if scaling min frequency is too low).
18) Performance:
Sets min frequency as max frequency. Use this while benchmarking!
So, Governors can be categorized into 3/4 on a high level:
1.a) Ondemand Based:
Works on "ramp-up on high load" principle. CPU busy-time is taken into consideration for scaling decisions. Members: Ondemand, OndemandX, Intellidemand, Lazy, Lagfree.
1.b) Conservative Based:
Members: Conservative, Lionheart, LionheartX
2) Interactive Based:
Works on "make scaling decision when CPU comes out of idle-loop" principle. Members: Interactive, InteractiveX, Lulzactive, Smartass, SmartassV2, Brazilianwax, SavagedZen.
3) Weird Category:
Members: Userspace, Powersave, Performance.
[SCRIPT] Smurfed Out V 5.0 (ultimate build.prop/init.d tweaks) Updated 3-18
Explanation of LMK Settings (Low Memory Killer)
and
Explanation of Adj and Minfree settings
When your phone boots up, a file inside the boot image (init.rc) sets the system parameters. Things like the path to framework files, setting up your networks, and setting the limits at which programs are killed off to free RAM are done by this file. Now a super-Android-geek might dig inside the init.rc file and completely customize the low memory killer, but you don't have to do this to still get good results. The init.rc sets up six different "levels" of open applications. Let's have a look at them:
FOREGROUND_APP: This is the application currently on the screen, and running
VISIBLE_APP: This is an application that is open, and running in the background because it's still doing something
SECONDARY_SERVER: This is a process (a service that an application needs) that is alive and ready in case it's needed to do something
HIDDEN_APP: This again is a process, that sits idle (but still alive) in case it's needed by an app that's alive and running
For the most part, we never want to adjust when these apps and processes are killed off. They are the things that the programs we use need to properly function. For the more bold and advanced users, changing settings for HIDDEN_APP settings is possible, albeit with a LOT of trial and error. There's two more settings, and these are the ones most interesting to us today:
CONTENT_PROVIDER: This is apps that provide data (content) to the system. HTC Facebook Sync? That's a CONTENT_PROVIDER. So are things like the Android Market, or Fring. If they are alive, they can refresh and provide the content they are supposed to at the set interval. If you kill them, they can't of course.
EMPTY_APP: I call these "ghosts." They are apps that you have opened, but are done with them. Android uses a unique style of handling memory management. When an activity is ended, instead of killing it off Android keeps the application in memory so that opening them again is a faster process. Theses "ghost" apps use no battery or CPU time, they just fill RAM that would be otherwise empty. When this memory is needed by a different application or process, the RAM is flushed and made available for the new app. To satisfy the geekier people (like myself) Android does this by keeping a list of recently used apps, with the oldest apps in the list given the lowest priority -- they are killed first if RAM is needed elsewhere. This is a perfect way to handle 'ghost' processes, so there's no need to touch this part
So when you see settings like this 8,14,40,50,60, 75 you start with the first setting and it looks like this
FOREGROUND_APP = 8
VISIBLE_APP = 14
SECONDARY_SERVER = 40
HIDDEN_APP = 50
CONTENT_PROVIDER = 60
EMPTY_APP = 75
You can manipulate these numbers so that they are better managed and give You different aggressiveness and a faster UI
For the Smurfed Out script the settings are as follows
Lite = 8,14,55,70,85,100
Medium = 8,14,75,90,95,125
Max = 25,35,55,70,150,250
Extreme = 25,35,75,90,150,250
Minfrees are set as well but they are equal to the LowMemoryKiller ADJ settings.
I personally run them at Max while using ICS but everyone's experiences will be different.
Nice idea.....good job.

Hello to all of you!
I've honestly searched the web and particularly this forum to find questions related to my current problem - finding the best settings for my phone's CPU that will fully suit me.. But there are also answers I've failed finding myself.
So, I have an Android mobile phone, Mobistel Cynus T1, which is MTK6577-powered. And I want to tweak its CPU controlling (assume that I already understand what all of that 'governors' and 'i/o shedules' stand for) with, let me say, the app SetCPU. The phone has been rooted already.
So, I installed this app and chose Continue Recommended in a pop-up window when launching for the first time, and the next frequencies and governors and shedules were defined for my phone:
Freqs: 250 500 667 750 834 1001 MHz
Governors: ondemand, userspace, powersave, hybrid, performance
i/o shedulers: noop, cfq, deadline
Here are the questions (sorry if the intro was useless or unnecessary, but I thought it is needed):
What is that 'hybrid' governor? I really couldn't find even a mention of it.
That upper list of freqs, are these freqs show the full range od freqs available for MTK6577, or not? If not, what freqs could be added?
What freq is the most energy efficient for MTK6577? I am asking this because I've read in some thread in xda-forum that the lowest freq doesn't mean the lowest battery consumption.
The 'powersave' governor, does it automatically finds the most most energy efficient freq or just sets the lowest? (referring to 3rd question)
If i set 'cfq' for all the profiles and 'noop' for screen-off profile, is it okay and wouldn't such a combination of shedulers harm my device?
Now come questions that as I think are related to the SetCPU app rather than to tweaking CPU in general:
My current working profile is 'CPU 250-834, hybrid, cfq'. Why than I often see that the proc increases its freq to 1000MHZ? There is no conflicting app and the SetCPU was allowed via a root-allowing app.
For the 'hybrid' governor, there are some settings which explanations I couldn't find:
down differencial
ignore nice load
io is busy
load critical grade
load high grade
load warning grade
load medium grade
load light grade
load critical
load high
load warning
load medium
load light
load up bound
load down avg times
Thank you for reading all this and double thanks for helping

For the 'hybrid' governor, there are some settings which explanations I couldn't find:
down differencial
ignore nice load
io is busy
load critical grade
load high grade
load warning grade
load medium grade
load light grade
load critical
load high
load warning
load medium
load light
load up bound
load down avg times
Thank you for reading all this and double thanks for helping

Does it include duoble tap to wake and sweep to wake?

I'm sorry, but I'm just do not remember which source files from HTCDEV.COM I took as a basis. K2_UL - that's for sure.

Hi, I have a suggestion. Would be great if you can mod cpu frequency table and add 2xx and/or 3xx speed, there is to big gap between 162 and 432MHz. 162MHz have big Impact on performance.
Hello, I flashed your kernel but if I try to change the frequencies of the CPU as soon as I close the program back to those first, any ideas? Also i have sod

I never aimed to produce highly productive kernel. I have always striven to save energy. I specifically did overclock separate, assembly to save the source code in the github repository. To everyone could take advantage of this. I do not plan to release further overclocked kernel version.

I use the program TricksterMOD. It perfectly sets all the necessary parameters when starting the phone.
Link to a new version (v010) - the second message. Github will update tomorrow.
Ok, thanks a lot, any suggestions on which governor to use?

Smartmax - for better energy saving. Ondemand - for better performance.
ADD.
If you view the my file version-2.txt - you can see that I experimented with other governor (badass, intellidemand, interactive, interactivex2, lagfree, lionheart). However, I have not noticed any particular advantages.
I also experimented with replacing mpdecision to auto_hotplug.

You misunderstood me. I want to say that 1xx MHz is very low speed, and it is OK for low cpu task. But if you play music, or running some other task in background cpu will run on next higher speed 4xx MHz, because 1xx MHz is not enough for such task so it will use more power than if it is run on 2xx or 3xx. So if the is some cpu speed between 1xx and 4xx MHz cpu should use less power.

Yeah, maybe you're right. I will try to add "a couple" of frequencies in the coming days. Although I doubt that when playing music, processor speed will be lower than 432.

Link to a new version (v011) - the second message.
If you are not hard - please, collect usage statistics processor frequencies when listening to music, etc.
Thanx in advance.
^Is cpu states log from BetterBatteryStates ok, or you want log from some other app?

Charge the phone. Reboot. Use the usual way (listen to music, make calls, etc.). At the end of the day - to see the statistics for frequency processor. Any program, that is able to display. I'm interested to see duration of use of each frequency.
Oki, I will post cpu states at the end of the day.

Listening to music with Spotify over WiFi CPU mostly stay on the 384MHz.
