HELLO AND SALAM SATU MALAYSIA
Since i was newbie about android,
i try to overclock my Xperia X8.
so i went to market and i found Antutu CPU Master.
the problem is i found something that i never heard before.::::::
"GOVERNOR"
could someone told me..what is governor actually...
and what different better the governor module?
i only found about smartass..the other module..i didnt find in xda forum.
i hope someone could help me here..before i accidentally brick my phone.
Cpu governor is control the Cpu freq.
- The OnDemand governor is the default option used by Android. It scales the CPU speed between the minimum and maximum speeds depending on CPU load. If the system needs more speed, the kernel will rapidly scale up the CPU speed.
- The Conservative sets the CPU speed in a similar way to the Ondemand governor, but scales the CPU up much less rapidly. This would theoretically save battery power, but may lead to less responsiveness.
- The Userspace governor is currently useless. It’s another way for applications to set the CPU speed that setCPU does not use.
- The Performance governor always keeps the CPU at the maximum set frequency.
Additionally, he makes reference to another option, which is not currently part of the setCPU app, so I am assuming that this is one that was removed in later versions.
- The Powersave governor always keeps the CPU at the minimum set frequency.
- Except for “Userspace,” no matter which governor you set, the CPU will always stay within the bounds of the maximum and minimum speeds you set in setCPU.

---------------------------------------------------------------------------
Governors:
OnDemand:
Ondemand stands for that it scales up on load in frequency and then detects the load and scales back to a frequency which is fullfills the "demand" of the current load dynamically. (AndreiLux)
Interactive:
Interactive scales by default in steps towards max frequency, Ondemand in its default implementation scales immediately to max frequency. (AndreiLux)
InteractiveX(v2):
The same as Interactive, but when you turn your screen off it forces the second CPU core offline until the screen turns on again.
Performance:
Will constantly run at the highest set CPU speed.
Powersave:
Will constantly use your lowest set CPU speed.
Conservative:
Conservative means that it scales conservatively, not that it is conservative. It pretty much very similiar to Interactive in that it scales up and down in frequency steps. It actually can be one of the most aggressive governors out there. (AndreiLux)
Userspace:
Rare in the word of kernels. Typically not used for mobile phones. But what it basically does is, it runs on whatever CPU speeds the user sets through an app.
Lagfree:
More aggressive kernel. It scales the CPU faster, reducing lag and performance, while maintaining decent battery life. Its main goal is to increase performance without reducing battery life.
Min Max:
Only uses your max screen on frequency, and your min screen on frequency.
Hotplug:
Based off of Ondemand. It allows a CPU to go offline with minimal usage. When you're sending messages, browsing settings, or other simple tasks, most likely one of your CPUs will be offline.
PegasusQ:
Samsungs Governor for multi-core phones. Based off of Ondemand. This kernel controls hotplugging as well.
Lazy:
This Governor doesn't scale as fast. It's really a lazy governor, it tends to stick in the same CPU frequency without changing as much. Which can be beneficial to your battery (if your CPU settings are conservative) or can reduce battery life (if your chosen frequencies are aggressive).
Nightmare:
A modified PegasusQ, less aggressive (Which means not as good performance-wise), and doesn't usually hotplug. It is good for a balance between performance and battery life. May prevent the 'Screen of death' as well, since it doesn't hotplug.
HotplugX:
Its basically a smarter Hotplug, to my knowledge, it shuts off the second core much faster, and is a little bit smarter with CPU scaling and power efficiency.
LulzActive:
Based off of the Smartass and Interactive governor(s), the newer version of this Governor gives more control to the user, and he CPU frequency parameters (Ask for a description if you need one) are smarter. Smart at scaling both up and down.
Smartass:
Based off of the Interactive Governor, this is an older version, but this Governor is (or was) one of the smartest Governors, and is smart with performance and battery. More below.
SmartAssV2:
A re-thought version of the original Governor. This one aims for ideal frequencies, meaning it makes up its own frequences in order to meet the requests the CPU needs. Scales down the CPU extremely fast once the screen is turned off, meaning you will get amazing standby times. No upper limit for the CPU frequencies in both the screen on and screen off state(s). (If you want a better detailed explanation of that, please ask.)
Lionheart:
Conservative-based governor off of Samsung update3 source (Line copied directly from a guide, thank you 'Amal Das'), scales aggressively. This Governor is strictly for performance.
BrazilianWax:
Similar to smartassV2, the only real difference is, it scales more aggressively than SAv2 does, which reduces battery life, while improving performance.
SavagedZen:
Based off of SmartassV2, similar to BrazilianWax, but this Governor tends to favor battery over performance. From personal experience, I can say it does a great job of doing so.
Scary:
Conservative-based Governor with some smartass features. Ramps speed up one at a time, and ramps speed down one at a time (ask for description if you don't understand). Caps your screen off speed at 245MHz. Scales just like conservative would. This Governor is more for battery life than performance.
Sakuractive
A governor based off of hotplug and ondemand. The phone hotplugs (when it can) when the screen is on, and can be described as a 'hybrid' of hotplug and ondemand
OnDemandPlus
A governor based off of OnDemand and Interactive. It provides a balance between performance, and saving battery.
DynInteractive
A dynamic interactive Governor. This Governor dynamically adapts it's own CPU frequencies within your parameters based off the system(s) load.[/SIZE]
Advanced CPU Governor settings:
I got most of my information from this thread.
Sampling rate:
Microsecond intervals the governor polls for updates. Assists in the Governor determining whether or not to scale up or down in frequency.
Up threshold:
Defines the percentage from 1 to 100 (percent). Happens less often when clocked at a lower speed, overclocks when you get up into higher CPU frequencies. Using a Governor such as OnDemand prevents it from overclocking nearly 100% of the time.
Ignore nice load:
If you set the value to '1' the Android system will ignore 'nice' loads when the CPU Governor scales up or down.
'Nice' load:
When you turn a process into a 'nice' load, it prevents low activity processes randomly becoming high priority processes, which prevents lag. What a 'nice' load is, is how it handles processes. You can 'Re-Nice' processes, and re-set how processes are determined, based on your current processes that you have. Which helps eliminate lag due to processes being re-prioritized.
Frequency Step(s):
Determines how much the Governor will increase, or decrease, based on your CPU speeds. *This doesn't apply to some Governors
I/O schedulers:
Deadline:
Set to minimize starving of requests. In other words, it is designed to handle system requests as quickly as possible.
Noop:
It handles requests in a basic 'first in, first out' order. So any requests that come in, will also be the first to be executed.
SIO:
A mix between Noop and Deadline. Basic process/request merging. One of the most reliable schedulers out there.
BFQ:
Gives each request a time budget. If the request is not met by the time it is given, the request is skipped. Smarter than the CFQ governor.
CFQ:
'Completely Fair Queuing' scheduler. Scales its requests in an effort to insure smooth task handling. Attempts to give each request equal I/O bandwidth. Typically, lag happens with this scheduler due to the effort of competing tasks on the disk because it tries to give equal bandwidth amongst all requests.
FIOPS:
Relatively new. No I/O seek time, ( potentially better for performance), balanced read/write times, one of the smarter I/O schedulers
ROW:
Read Over Write. It will cause better read times for pictures/media, but when transferring data/installing apps, significant reduction of performance will be present.
V(R):
Best for benchmarks due to performance of requests, but is considered unstable due to random drops in performance. Semi-based off of the CFQ scheduler.
FIFO:
Takes each process in one by one, fair process queuing, balanced queue handling as well, processes go in and out in a numerical fashion.
TCP Congestion Avoidance Algorithms:
Tahoe:
Limits unknown packets being received. Limits the congestion window, and reset itself to a slow-start state.
Reno:
Basically the same as Taho, but.. if 3 of the same packets are received, it will halve the window, instead of reducing it to one MSS. It changes the slow start threshold equal to that of the congestion window.
Vegas:
One of the smoothest (next to cubic), it increases the timeout delay for packets, which allows more to be received, but at a higher rate. It also has set timeouts, which helps with speed because it's constantly being refreshed.
Hybla:
Penalizes connections that use satellite radio. Not usually used with phones.
Cubic:
One of the best, most recommended TCP options available. Less aggressive, Inflects the windows prior to the event. Used in Linux.
Westwood:
A newer version of Reno, and another commonly used one. It controls parameters better, helping out streaming and overall quality of browsing the internet. One of the most 'fair' algorithms out there, and is one of the most efficient algorithms to date.
CPU Governor recommendations:
Performance: Use Wheatley, or Performance.
Battery life: Use lagfree, Hotplug, PegasusQ, InteractiveX, or Sakuractive.
A fine balance: Use SmartassV2, Hotplug, or Sakuractive at less aggressive CPU frequencies.
Android tips:
Developer options:
Go to settings>build number... And tap 'build number' 7 times, go back, and you have now enabled developer options.
Force GPU rendering:
What it does is, it force enabled 2D drawing (such as scrolling, and anything non-game/app related) to the Graphical Processing Unit, instead of the Central Processing unit. What does/can this do? It has the potential to save battery life, and takes some of the load off of your CPU, which increases overall smoothness and reduces lag.
Keeping WiFi on during sleep:
What it does is, as this ^ suggests, keeps WiFi on while your phone is awake. To enable this, (and there are many ways.. I'll give you the way I'd do it.) Go to settings>WiFi>WiFi settings (3 vertical dots)>Advanced settings>keep WiFi on during sleep.. And set it to 'always' or.. You can use tricksterMOD and enable that via the GUI (Graphical User Interface)
WiFi Supplicant Scan Interval:
Before you freak out, I will give you what it means. What it means is this: how often your phone scans for a WiFi signal. Typically, it is 15 seconds. The recommended number is 300. To change it, you can typically find it in the build.prop manually edit it on your computer, or use an app such as ES file explorer and run it as root. Go to build.prop and look for: wifi.supplicant_scan_interval=x. And change x (usually 15) to 300, save, exit, and reboot. Please note it is not available with some ROMs that are driven towards a stock-ish feeling. Such as CM ROMs, or any derivative of that ROM.
Tips to get better battery life:
Turn off sync, location, Bluetooth when you're not using it, along with WiFi and data, don't use app-killer apps, lower CPU frequencies, and change your Governor to something less aggressive if you don't use it for heavy gaming.
Status bar with 1 finger, panel with 2:
If you want to access the tile settings quicker. Drag your status bar down with two fingers. If you want to bring down the status bar, touch the top of your screen and slide your finger down.[/I]
Autobrightness sucks!!:
Download an app called 'lux' and use that app. It'll take of any problems you're having, plus it'll save battery.
Changing your phones screen density:
In your build.prop, there is a line of code that looks like this: ro.sf.lcd_density=320, change it to 240 for a tablet-ish feel. Don't go under 160 though, you'll have endless bootloops
Change your bootanimation:
Go to system/media, you'll see bootanimation.zip, replace it with your desired bootanimation, change permissions to r-w-rr (read-write-read-read), and reboot. (Assuming you're doing this on your phone)
Block ads:
Download an app called 'adblock' on the play store, run it normally, accept the SU request, hit 'skip' and run the program, exit out, and reboot!
4x MSAA:
4 times MultiSample Anti-Aliasing. What this does is smooths out edges in apps that support AA. It makes your game look better, enhances graphics, but has the potential to degrade performance due to the screen enhancement. To enable this, go to settings>developer options>and check the box that says 'Force 4x MSAA'
zRAM:
Avoids disk paging, compresses your RAM. Disk paging means the way your phone saves temporary data. It helps with fragmentation of your disk and the physical space, which, over time, keeps speed stable and prevents any system slowdowns.

thanQ vvvery much!!
very useful thread..
can i ask you something?
my phone is very fast and responsive sometimes.. but if i keep screen off for some hours, after turning on when i click on an app (even if it's running on background) it'll
launch with some delay.. i don't like it at all..
i don't play heavy games.. but i need my phone response each touch and launch certain app as quick as possible.. which Governor, Scheduler do you suggest?

Hi,
I'm using Co-Core 8.2 and I want to test One Power Guard to improve my battery life.
But I don't have any idea about which CPU governor and I/O scheduler to choose.
Could someone tell me which combination provides the best balance between power-save and performance?
I'm on Jelly Bean 4.1.2
NB. Cocafe recommends PegasusQ as CPU governor and either SIO/ROW for I/O scheduler but I would like to get some feedback from people already using One Power Guard.
Thanks in advance

Thanks for the answer. I will give a try with Pegasus
However I noticed that sioplus is not available on One Power Guard settings. Only row and sio.
Is sioplus available in Co-core 8.2?
These apps like this just drains your battery. If you want play with CPU, download a CPU controller app. (like SetCPU) and install CoCore 9.0 which is newest version.
When you don't use phone ; 600 MHz Max & HotPlug
When you don't use phone V2 ; 600 MHz Max & Ondemand & deeper sleep status
When you lock phone, don't decrease speed (too much) because it will use whole CPU if it needs ; 800 MHz Max & Ondemand Q/Lulzactive Q/Pegasus Q
When using ; 1000 MHz Max & Ondemand/Interactive/Lulzactive Q/Pegasus Q
When you get mad and crazy about performance, lock the min to max; 1000 MHz min and max & Ondemand & SmartAss (still exists or not I don't know)
If you increase minimum speed it will keep it. So I suggest always keep min to 200MHz. (if exists 0 MHz I don't remember it too)
Edit: and don't go deeper sleep if you use hot plugger governors like Hotplug, Pegasus, Lulzactive Q

Thanks guys,
I will compare the battery draining with One Power Guard just to give it a try.
If I don't notice any improvement then I will tweak with SetCPU

Hi again,
What exactly do you mean wit "deeper sleep"?
Is that an option or when the display is off after several minutes?
Sorry for my ignorance

Go to the CoCore's thread you'll see. It's deep sleep level which can increase your battery life when you don't use the device. It's not about using, it's about when it's stand-by.
Ok
After one day even if One Power Guard is a nice app I prefer to switch governor depending on the display status. So I was thinking about using tasker (instead setCPU) which is already running on my phone and this way not adding more background processes.
I set a couple of task using the CPU control from tasker. It is working fine switching governors but I noticed that the frequencies (min and max) don't change. I tried even with shell script and still I don't get to set the max frequency. Then I prefer to make you a couple of questiosn:
-In tasker when using the CPU control. If I change governor. Should it be set in both CPUs (0 and 1) or only in a single one? In my case i set the governor in both.
-I use the terminal to check the current governor and max frequency (for instance for the cpu0)
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governorcat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
As said above the governor is succesfully changed but that's not the case for the frequency. Then I tried to run a shell script to change the max frequency as follows:
echo #frequency > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
But it seems not working neither. So I wonder if I'm doing something wrong.
NB. By the way I'm happy using the governor hotplug while not using my phone (thanks for the advice). In normal use I set pegasusq with sio and seems working great.
Hello all.
After about a month of researching and testing with the Galaxy S5, I'm finally happy with my SmartKernel profile, with the interactive governor carefully tuned, using known resources and countless trials and errors, as well as other various tweaks, like VM and I/O scheduler, and decided to publish on it's own thread.
The main resources I've used for the Interactive governor tuning includes the well known:
Android Modders Guide;
[GUIDE] Advanced Interactive Governor Tweaks; Buttery smooth and insane battery life! for Nexus 5X; and it's twin
[GUIDE] Advanced Interactive Governor Tweaks; Buttery smooth and insane battery life! for HTC Evo 4G.
First of all, this tweaks should be a little sensible to the ROM, kernel, apps, and other tweaks your using. Like, I just found out that Havoc pie style quicktile settings use way more juice then if I turn it off and go back to Oreo default. Bellow you will see the apps I mainly crafted this profile in mind.
For reference: I have a klte with latest Oreo Havoc installed, nano OpenGapps, Magisk and the SmartPack kernel. For apps I use Facebook lite, cause the normal app is just a big hog, whatsapp and instagram social apps. Chrome. I don't use the Google App or Greenify(uninstall/delete velvet). And play lots of games like Clash Royale, Star Wars Force Arena and Arena of Valor. BetterBatteryStats.
And a lot of random apps that normally don't stay on the background.
DESCRIPTION
On the SmartPack manager profile:
. HIghly Efficient Interactive Governor Tunables (most important part);
. No Touchboost or any other boost, only the governor dictates to CPU in which clock it should to be;
. Overclock disabled, but can be enabled at you will;
. No underclock, I do undervolt my CPU but this you need to find your specific device numbers, mine won't cut;
. LazyPlug Hotplug with all 4 cores on all the time (better performance while using and battery savings while at idle);
. I/O Schedulers: ZEN (the L-Speed profile complement this part, with it's scheduler tunables);
. READ-AHEAD internal 1024kb (for 16GB or more) and external 512 kb (for my 8GB SDCard, adjust accordingly to yours SD Card size conform described here
. Adreno Idler disabled: it doesn't make any effect;
. Speaker Driver Leakage disabled and Boeffla Sound enabled with 0 gain as it does make a difference, at least with ViperFX magisk module installed;
. Screen minimum RGB set to 1 (0 won't stick), for a darker dark on our AMOLED, plus some tweaks;
. Led blinking fade enable;
. VM tweaks: dirty_ratio 30 and dirty_background_ratio 15; for minor battery improvement, with a perceptible lower termperature/cpu usage and almost imperceptible performance hit;
. VM tweaks: page-cluster 1; for better multitasking/memory management
. VM tweaks: oom_dump_tasks 0; disable depuration of dumping tasks, less cpu needed.
. LMK values: 32 48 64 128 176 208 (MBs)
L-Speed Profile
. Logging and I/O stats disabled;
. Animations speed set to 0.25x;
. System battery save trigger at 20%;
If you need to provide or read logs, enable logging and i/o stats back on l speed; i/o stats and oom_dump_tasks 1 on smartpack manager
INSTALLATION
Unzip the attached file and import with SmartPack Manager:
The attached profile should be imported, applied and marked as to run "On Boot" to make effect. It will only work with SmartPack Manager and Kernels for both Nougat and Oreo, maybe even Pie. Just try it, and report back. If you wanna fine tune it. You need to use an app or enable the "show cpu clocks" option if your rom supports it (like Havoc, RR and many more), and monitor at which frequencies the lags happens, while doing the jobs you want the CPU to be efficient at. And mainly tweak the target_load according, maybe above_high_speed delays of 1,7GHz clock and above. You need to read the guides more in-dept too see exactly how to do it, but I'll paste here the most important parts on how to tweak this settings more to your Galaxy S5, with your particularly apps and ROM:
soniCron said:
Optimize Idle Frequency
Now that you've got the base configuration, we need to tweak it so that the CPU stays at your efficient idle frequency (384Mhz in this case) without spontaneously jumping when your phone is actually idle. To do this, open a CPU monitor that displays the current core frequencies (I like CoolTool, but you can use what you like as long as it doesn't significantly impact the CPU use--you're best off using a passive monitor and checking the results after 30-60 seconds of no activity), watch the frequencies and see how often they go above your efficient idle frequency when you're not doing anything at all, and adjust the following:
timer_rate - If your idle frequency is not being exceeded much, adjust this downward in increments of 5000 until it is, then increase it by 5000. If your idle frequency is being exceeded often, adjust this upward in increments of 5000 until your CPU primarily stays at or below your desired idle frequency.
above_highspeed_delay - Only if your timer_rate has matched or exceeded 50000 and still won't stay at or below your desired idle frequency most of the time, set timer_rate to 50000 and adjust the "20000" portion of the value upwards in increments of 5000 until the idle frequency has stabilized.
The lower these two values are, the more snappy/lag free your system will be. So try to get them as low as possible without the idle frequency being exceeded too much, as this inversely affects the snappiness and efficiency of your phone when you're not doing anything. Lower = snappier but uses more CPU when you're not doing anything (such as reading a webpage); higher = less snappy but stays in a power saving state more often reducing CPU use when you're not interacting with the device. These are the most critical in determining your idle power savings, so keep that in mind if you want the most battery life!
Enhance Task Responsiveness
Now use the efficiency and nominal clock rate correlations you made for your master clock rate list in the section above and adjust your frequencies to suit your usage patterns. For example, I had web page scrolling as my 710Mhz/864Mhz rates, so I will open a web page and scroll and see how everything feels. If it feels sluggish, I will increase all the references to "710000" in both above_highspeed_delay and target_loads upwards to the next available clock rate until that task is smooth. What you are looking for is constant poor/sluggish performance when the task you're testing for is using its highest CPU use. If the task becomes sluggish/stuttery as it winds down (such as a scrolling webpage slowing to a stop), we will address that next, so do not take that behavior into consideration as you adjust these values! If the task is smooth until (or after) it slows down, then you have reached your optimal clock rate and can move on.
If you need to exceed your nominal clock rate for a particular task, first measure it again just to be sure you had it correct. If you did indeed have it correct, leave it at your nominal clock rate and adjust the value after the colon next to the task frequency you're tuning downward in increments of 5. For example, if my setting of "864000:80" is still not sufficient, I will adjust it first to "864000:75", then "864000:70", and so on until the task is smooth. However, it almost certainly won't come to this, but if you reach ":50" and the task still isn't performing how you want, set it back to ":80" and increase the clock step once more, then decrease the ":80" until it is smooth.
Do the same for each other frequency in your master clock rate list until you are satisfied. If you have chosen to use more than 2 primary clock rates, add them and use ":##" values between the two surrounding frequency values.
Fix Stuttering
Now that you have adjusted your frequencies for optimal high CPU use in each given task, you may notice some stuttering as the task winds down. (Such as a scrolling webpage slowing to a stop.) If this bothers you, you can tweak this at the expense of some (minor) battery life by adjusting min_sample_time up in increments of 5000 until you are satisfied.
If you have exceeded a value of 100000 for the min_sample_time setting and still are not satisfied, change it back to 40000 and increase (and re-optimize) your idle frequency by one step. This will impact battery life more, but less than if you were to keep increasing the value of min_sample_time.
Adjust High Load Clock Rates
You're almost done! Now you can leave everything as is and be satisfied with your amazing, buttery smooth, snappy experience, or you can optionally tweak things further to either increase the responsiveness of high load tasks (such as loading image previews in Gallery) or increase battery life somewhat.
Adjust the final delay value in above_highspeed_delay to suit your needs. The default ("150000") means that the CPU load at the highest set frequency (default "1026000") will have to be sustained for 150ms before it allows the load to go above that frequency. Increasing this value will prevent the CPU from reaching higher frequencies (which may be unnecessary) as often, saving battery life. This will come at the expense of burst-type high CPU load tasks. Reducing it will allow the CPU to reach higher frequencies more often, at the expense of battery life. However, adjusting this is probably unnecessary, as it will most likely not yield any perceptible difference in performance. It is recommended to leave this value at its default.

Besides CPU Voltage and Battery, all tabs on the manager are modified and tuned to achieve best performance, while having best efficiency possible. Is not a battery or a performance, but a efficiency profile.
Refer to this thread if you wanna undervolt your device with a well know secure margin for the CPU Snapdragon 801 2.5ghz MSM8974AC, which our Galaxy S5 contains:
[GUIDE] Snapdragon 805/801/800/600 Clock & Voltage (PVS bin) guide by HD2Owner I've managed to achieve much lower voltages then PSV15+ devices (refer to the sheets).
I also attached the excel spreadsheet I've made with all this thread information, both governor guide equations on target loads, undervolting guide findings, and made my own base calculations and settings. Feel free to use, modify, and discuss it with me. You will see that I based the most efficient clocks in an original thought about which ones are the most efficient, instead of plotting the differentials between voltages of each clocks, I did plotted the difference of the clock divided by voltage, which on itself should be how much voltage 1 mhz uses, on each clock rate. So, the higher the number, more speed each clock rate give us by voltage used. It's kinda complicated and idk if I explained it the right way, and even if it really makes sense under scrutiny, but I couldn't think why not myself, so, any inputs are welcome.
I own my thanks to all the following XDA fellows, without them, I could not have achieved this:
@sunilpaulmathew for the SmartPack Kernel which is the only kernel for the S5 that can turn that damned MPDecision off and SmartPack Manager;
@soniCron for both of the governos Guides;
@Saber for the Android Modders Guide which is immensely helpful.

@justjr
Nice work friend. Great to see that your finally open a place to share your findings. In my opinion, your profile should work on any klte device with minimum kernel support. I haven't seen much SmartPack specific stuff in your profile except some hotplug related things. So, if you make it as a shell script instead of KA/SP-Kernel Manager profile, it shall be beneficial for everyone. Anyway, as usual, I'll kang your changes to my kernel default profile

I think this profile should work on original Kernel Adiutor, or any fork of it, shouldn't it?
It should work on any other kernel if the changes really stick, and uses the same paths, but MPDecision will mess with frequencies all the time. It would still follow the governor tunables anyway, but it will interfere with it and in the end will not gain too much efficiency out of it.
Actually I only state it is for SmartPack specifically because of the fact that is the only one I can disable MPDecision on our device, and because I included all the tweaks other then just governor tweaks.
Actually I'm kinda lazy right now, but I could do a shell script if any demand for it shows up.

Well, official KA (free version) doesn't allow to import profiles (paid feature), but all other mods does.
and yes, it is supposed to work on every klte device as long as the sysfs paths exist. Means it should work on any custom Kernel with lazyplug support (most of the other stuff are actually included in the stock kernel itself). Of course, the default settings provided by the kernel devs might conflict. e.g., as you said, MPDecision, although the line "stop mpdecison" in your profile will disable it. By the way, I'm not the only one who disabled mpdecision and relay on other hotplugs in this klte community

Oh, really? Which one? I must had missed it. I've tested all kernels I could find. At least all the remotely up-to-date, like venom, tuned and boeffla kernels. I didn't see any option to change hotplugs on any. There were hotplug profiles, to keep cores online and stuff, but everyone of them keep changing min and max frequency at MPDecision will.

Boeffla and Venom largely depends on MPDecision. However, as I remember correctly (on the basis of the code review, not from my experience, I never used it by myself), the Tuned kernel by @fbs disabled MPDecision upon booting to work well with its own Tuned hotplug.

I tested it too. And although he claims he uses hes own hotplug, it behave the same as boeffla and venom, it has the same profiles, and it does changes min and max freq out of my control.

no it doesn't change any freqs
it works by disabling or enabling cores, just that.
if any cpu reaches the maximum frequency, it enables one more core (as the other ones are already giving their best)
if any cpu reaches the minimum frequency too many times, it disables it (as it doesn't seem to be needed)
so in any moment you can have all 4 cores enabled or only 1. even with display on or off, it doesn't matter
mpdecision will NEVER let you use just 1 core, and it doesn't react as fast: battery hog

Alright, sorry then, it seems my memories got clouded or something, as I've tested it about a month ago. I might go back any day just to test that. Thanks for giving us one more kernel option! :good:
UPDATE OP WITH
Description
Changelogs
New profile 011118, changelog:
. Few governor tweaks
. Removed Virtual Memory and LMK tweaks, let it on default or use L-Speed to optimize, it does a much better job then me
Also uploading the L-Speed profile I use so those who want to use it like I do, but you can choose any VM and LMK profile that fits your needs on the app. Just don't use the governor tuner because it will mess with my tunings, and l-speed governor tuning is a generic one for all devices, VM and LMK is OK to use generic tweaks, but not on governor.
@sunilpaulmathew I took a look at l-speed virtual memory and lmk profiles and they make incredible sense, take a look yourself, they may be what you need to put o that spectrum profiles, because above all they are device independent and do make a noticeable difference.
Is it valide for stock rom (6.0)?

What kernel? It should work if the kernel have lazyplug or alucard hotplug, if is the late you just have to enable it.
Updates
SmartPack Manager Profile 031118:
. Governor tunning: better high load management;
. Included back only 3 sane VM configurations, no more freezing, better cooling (less cpu needed, while performance barely took a hit)
. Sane LMK configurations, kills apps not being used faster, retain some multitasking while not let it slow down the device
LSpeed Profile 031118:
. Removed most tweaks, only left minor stuff, refer to the OP.
L Speed profile is not really needed, SmartPack will do 99% of the job.
OP: descriptions for both profiles updated.
New profile.
I returned to Nougat, RR 5.8.5, same configs works awesomely and the device is cooler/faster then with Oreo. But still will works the same with both N/O and even Pie, not tested.
I also reinstalled Hearthstone as a high load app so I could tune the governor better for it, and up to 1490 MHz nothing is changed, and changed a bit target_loads and above_hispeed of the clocks above it so Hearthstone (and any other high load apps, or, using split screen with youtube) runs smoother/without lags and tasks like opening an app will finish faster, and also go back to a lower clock faster because of that. So, in the end it stays most of the time at lower clocks anyway, only difference is that it will jump faster when needed for less waiting time/lag.
Just to clarify, this is not suppose to waste battery, or drain it faster. As an efficiency profile the goal is to do the job you the want faster the possible, ramping up to the clocks that the jobs demands, without lags (or minimal lags) and go back to idle/lower clocks as soon as high clocks aren't needed anymore, so it don't overstay at a higher clocks then it's needed, very simple.
So, going to a high clock doesn't mean less battery life, finishing a job fast and going back to idle is the key to achieve more battery life, specially during deep sleep, when you really want your device go back to deep sleep fast, but also at any other time. Watching youtube, browsing and using low demand apps still uses the same clocks.
Also, on top of that you will spend more time USING the device instead of WAITING for it to finish a job. Battery life is very subjective, and SoT doesn't mean nothing IRL, I mean, are you spend that SoT waiting for a job to finish or to actually use the device?

In that case nothing is needed, the configurations related to the absent sd card will not be applied.
Ok guys. I was wondering why my device was heating a lot more these last 2 days. Turns out both Alucard and Lazyplug were accidentally activated on 081119 profile. Turn one of them off and everything will be a lot better. Sorry for that. I will upload a new profile very soon.
