UNDERVOLTING USERSPACE
DOCs:
Stratosk - About Undervolting
Stock kernel uses a paramater boost_uV.
By default, is added in voltages but it can be disabled.
The value of boost_uV is 0 for Slow bin chips and 25000 uV = 25 mV
for Nominal, Fast and Faster.
The boost_uV may be disabled using this command:
(= undervolting by 25000 uV in Nominal, Fast and Faster)
echo n > /sys/module/acpuclock_krait/parameters/boost
3 more paramater that handle undervolting:
- lower_uV: undervolting value for lower frequencies
- higher_uV: undervolting value for higher frequencies
- higher_khz_thres: above this frequency (default 1350000KHz) higher_uV will be used.
Else lower_uV will be used.
Undervolting value is subtracted from stock voltage. The final voltage for each frequency is calulated:
Vdd(final) = Vdd(core) + boost_uV - uV
So, to undervolt frequencies 384000-1242000 by 25mV and the other frequencies by 12.5mV use these command:
echo 25000 > /sys/module/acpuclock_krait/parameters/lower_uV
echo 12500 > /sys/module/acpuclock_krait/parameters/higher_uV
The higher_khz_thres maybe changed using this command (for example to use higher_uV from 981000KHz):
echo 918000 > /sys/module/acpuclock_krait/parameters/higher_khz_thres
Debugfs file (acpuclk/acpu_table) to show the acpu table frequencies and voltages.
For example to get the information about the current status use this command:
cat /sys/kernel/debug/acpuclk/acpu_table
CPU PVS: Fast
Boost uV: 25000
Boost uV enabled: No
Higher KHZ threshold: 1350000
Lower under uV: 37500
Higher under uV: 25000

Click to expand...
Click to collapse
Would like to know also. I prefer faux, but don't know if it will play nice.

Was waiting this kernel for my 4.3 baby....Thanks AK !
Whats is the difference between intelli hotplug and dynamic? Which is better?
TricksterMod is the preferred way to change kernel settings/parameters ?
Yes, it's in my eyes the best mod for kernel tweaks

Just installed! Will come back with results as soon as I get them.

NTFS support
F2FS
INSTALLATION
1. Install zip from recovery
2. Follow the instructions, if you don't know what to do, use the pre-selected options
3. Wipe cache/dalvik cache
4. Reboot
It is recommended to disable or increase the screen timeout in TWRP recovery. If the screen timeout is enabled in TWRP, there may be a black screen after exiting the Aroma installer. This is nothing to worry about. Simply hold power and volume down and volume up buttons until it reboots. The installation will be fine. If things get stuck in aroma, simply do this reboot method and immediately hold down to get to bootloader mode, then select recovery and start from the beginning.

Great info to actually read and know!
Hypernova version has all kinds of stuff that's been added from the good @franciscofranco, and the most important and amazing, IMHO, is the mako_hotplug_driver. With this, we have eliminated most governors, and now exclusively run interactive. We now also have some extra options with this interactive governor that we can set to customize the user experience smoothness, and battery life. Down below is how to work init.d scripts, which is suggested as a great set it and forget it method, but if you are trying to mess with things quickly and in user land with an app, you will have to use francos. Unfortunately, our phone is only supported by the paid version also, so looks like it's time to open the wallets and show your appreciation! Bought this personally as soon as I got the hotplug up and running. 100% worth it.
Advanced Interactive Governor Tweaks; Buttery smooth and insane battery life!
Here's some info on the pieces used from his kernel, and the app, and the guy himself it seems.
Code:
Information about the kernel
People generally change kernels for battery savings and to add features the stock one doesn't offer.
Franco's kernel has several advantages over the stock one in terms of battery saving saving features,
one of my favourite being the removal of MPdecision which in lay-mans terms changes the min and
maximum speed the CPU can run at based upon live battery temperature checks. Franco's hot plug
driver always keeps 2 cores online and always them to scale from 300mhz to 2.3ghz and based upon
load conditions will online cores 3 and 4 if required. When you touch the screen the screen the CPU
speed is boosted to approximately 1.5ghz for just over a quarter of a second and when load is reduced
the CPU speed is able to lower quickly back to lower speeds thanks to his tuned interactive
governor. Franco has created a governor for the GPU named interactive which works very much like
how the CPU equivilant does. Franco has added some newer drivers for WiFi which also helps reduce
idle battery drain while your on a busy WiFi network. Franco has also added an interface where you
can boost microphone, speaker and headphone gain levels for audio enthusiasts as well as an
interface to allow screen calibration and load pre set profiles to improve your experience with how
your display looks! There's clock speed control, voltage control, governor control, hot plug control.
You get the idea its full of cool features which can be controlled with the paid Franco.Kernel
Application (see later in the thread)

Here are some lines I've found around the interwebs as a reference for myself for some time now. All of this is set, but hey, it never hurts to learn how it all works behind the scenes.
This is not a shell script, and cannot be run as one as-is; it's just a bunch of commands. UV should never be set with init.d in case they are unstable.
These are old values, some may be good, some may not. Please ask, or do some research on what is suggested for current cpu and phones.

best min frequency:
lowest possible setting (300mhz in case of MSM8974)
i highly recommend to run those values (exept if you are actually playing demanding 3d games).
use trickster mod frequency lock feature to do so. you will experience amazing battery life.
how to get the maximum battery life:
if you have a MSM8974AB pvs 6 for example, try the following steps:
try the next higher pvs levels (pvs7). don't try AC pvs values on AB chips.
AB chips are binned for lower frequencies while AC are binned for higher frequencies (duh).
so if you have a AB chip, work your way up the AB pvs values until you have freezes or similar and move back.
if you have a AC chip, work your way up the AC pvs values etc...
if you found highest setting that does not cause any problems after intensive testing and usage:
congratulations, you did it.
how to get the maximum frequency:
first try higher than stock maximum clock and see how it behaves.
if you don't reach your desired clockspeed, try the next lower pvs setting of your chip. yes, i said LOWER.
this gives the processor more voltage to reach higher overclocks.
i don't recommend it tho since we all want our phones to last as long as possible usually.
Thank you very much to @flar2 for all his work, and assisting people like me to port it to a device that otherwise would have no such love!
Gigantic thanks to @franciscofranco for his additions, fixes, and mako_hotplug!

Oh Snap, what is going on Mass, Glad to see your kernel all over the place. Thought I was in the Sprint forums for a sec.
About time we got a new kernel.
Thanks a lot @MassStash. Will report in a bit. Gonna flash now.

Dan, how the hell you find this so fast!? lolol Thanks man, super stoked to post this one as it's such a larger footprint to see be a part of. Excited to see how much people hate it lol
PSA: this current version is made with venom ramdisk and is flashing a full boot.img with it. Because I'm old school still, spr and vzw have seen some issues with txt and calls. Pretty sure it's that, so I'm looking into using anykernel like asap so that the zImage is simply injected into which ever rom you are on. Also, when I do this, I will be able to use one download link for all variants because it is already the same exact zImage and dt.img being used as I have the unified dtb's from capt's brilliant brain. Everything should work great, just wanted to make sure I gave everyone a heads up before the complaints. Thanks a million to anyone that joins in here, and happy thanksgivin to the USA peeps!

Just a heads up dunno if it still exists but after you flash the kernel changing the frequency caused the CPU freq to stick at 300mhz not sure if Mass has worked this out or not.
So just make sure not to change freq in an app just reflash kernel and do it with in the aroma if changing causes lag this is why other than that this kernel is freaking beast

There ya to again @dandan2980 stealing my THUUUNDAAAAAA again.
At least you didn't write up a 2,000 word essay this time to simply say "don't change the frequencies or you'll have to reflash" :thumbup:

Don't forget the thanks button for EVERYONE that has helped you.

These guy's responses are usually more useful than mine haha
After flashing, I changed a few things in fauxclock and phone was extremely laggy. However, after a full reboot, everything is running buttery smooth. Will report on battery life later. Thanks again. ?

Reflash kernel and don't change the cpu freq at all in a cpu app you can only change freq in the aroma installer a little bug that needs to be worked out
Very good kernel
So far so good
Thanx for the great job
This kernel is great so far awesome work dev.

Now more detail about some features:
Governors
PegasusQ
Governor from Samsung with hotplug support. Perhaps, the most tunable and flexible one.
Parameters description:
sampling_rate: the interval with which governor will be carried out. Less value - better responsiveness, but at the same time, more load for CPU by governor itself.
sampling_down_factor: amount of iterations governor will stay at highest frequency before go down.
up_threshold: load threshold in % above which CPU frequency will be increased.
up_threshold_at_min_freq, freq_for_responsiveness: at frequency lower than freq_for_responsiveness will be used up_threshold_at_min_freq threshold - provided for better responsiveness.
down_threshold: load threshold in % below which CPU frequency will be decreased.
freq_step: step of frequency encrease in % from maximum frequency.
hotplug_freq_*: high and low frequency thresholds for making decision about hotplug of each core.
For clarity, it looks like this:
Code:
static int hotplug_freq[4][2] = {
{0, 1596000},
{208000, 1795000},
{416000, 1996000},
{624000, 0}
};
In this array left column is frequency at which core will be disabled; right column - frequency at which will be enabled next core.
hotplug_rq_*: analogous parameters set (array), defining queue task length for making decision about hotplug of each core.
Code:
static int hotplug_rq[4][2] = {{0, 50}, {50, 100}, {100, 150}, {150, 0}};
For example, second core will be disabled after reaching 208MHz frequency and amount of tasks must be less than 50;
third core will be enabled after reaching 1795MHz frequency by second core and amount of tasks more than 100.
cpu_up_rate: amount of governor iterations cpu should stay at defined frequency for enabling next core.
cpu_down_rate: amount of governor iterations cpu should stay at defined frequency for disabling last active core.
down_differential: defines load in % which must be less than up_threshold to go to lower frequency.
hotplug_lock: lock amount of active cores.
min_cpu_lock: limits min value of enabled cores.
max_cpu_lock: limits max value of enabled cores.
up_nr_cpus: defines how many cores to enable at a time.
AbyssplugV2
Based on Conservative, has hotplug support. Pluses: pretty simple, hence doesn't load CPU by himself. Frequency increases sequentally, after reaching max frequency - enables next core. And vice versa. Minuses: often enables / disables cores (what in itself is energy intensive).
Distinctive parameters:
up_threshold_hotplug: load threshold in % above which will be enabled next core.
down_threshold_hotplug: load threshold in % below which will be disabled last active core.
boost: load threshold above which frequency will be increased through step (for exaample., from 208000 immediately on 624000)
Optdemand
Governor by Hisilicon, based on Ondemand. Backported from Honor 4X/4C. Distinctive feature is each frequency has its own thresholds to go to higher or lower frequency.
Distinctive parameters:
go_hispeed_load, hispeed_freq: after exceeding go_hispeed_load threshold, CPU goes immediately to hispeed_freq frequency.
up_thresholds, down_thresholds: above and below load thresholds for each frequency. For clarity:
Code:
static unsigned int operating_points[7][3] = {
/* kHz up_threshold down_threshold */
{208000, 60, 0},
{416000, 60, 30},
{624000, 70, 40},
{798000, 80, 50},
{1196000, 85, 50},
{1596000, 90, 60},
{1795000, 95, 70},
{1996000, 100, 80},
};
For example, for frequency 624MHz, if load will go below 30%, will be calculated new lower frequency according to new load value; if load will go above 70% - frequency will be increased.
boost: frequency will be increased to hispeed_freq
bostpulse_duration: duration of boost in microseconds.
Interactive
Google's gold standard governor. Updated to 3.4 kernel branch
Impulse
Based on Interactive governor. Good responsiveness.
USB Fast Charge
Increases charge current when connected to USB. It has sense only when connected to USB 3.0
Can be enabled by writing "1" into /sys/kernel/fast_charge/force_fast_charge file or by third party applications.
Disabled by default
Intelli-Plug
Hotplug driver for governors not supporting hotplug.
Activated and deactivated automatically depending on chosen governor.
Parameters are in /sys/module/intelli_plug/parameters
nr_possible_cores: max cores affected by driver.
nr_run_profile_sel: has several profiles :
0: balance default
1: performance
2: conservative
3: eco
4: eco extreme
screen_off_max: max frequency at screen off.
touch_boost_active: enables additional core at screen touch disabled by default
CPU undervolting
Undervolting values can be set for each frequency individually. Regulator has step 8mV starting from 700mV. I've got such stable values:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But you should start from higher values. I've made a test: CPU locked at frequency 1795MHz, RAR creates archive with 4 threads in 10 minutes. Average CPU temperature during this time was 56.124 degrees, with undervolting average temperature became 51.119 degrees. I.e. average temperature became lower for 5 degrees which means less power consumption.
Comparative graph:
GPU undervolting
Since I couldn't find any common used sysfs interface and applications supporting it, you can make it using script (see init.d spoiler).
My stable values are:
Code:
160: 860 -> 700
266: 860 -> 732
355: 876 -> 764
533: 956 -> 860
700: 1052 -> 924
But most probable, you will have troubles with such values, try to find suitable for your own.
3DMark Ice Storm Extreme showed average temperature decrease from 61.587 to 55.502 degrees.
Comparative grapth:
DoubleTap2Wake
Screen on by double tap on it. Has two parameters in /sys/android_touch
doubletap2wake: enables dt2w. Possible values are:
0: disabled default
1: active at all screen
2: active at top half
3: active at bottom half
4: active at navbar
dt2w_duration: Since I couldn't implement waking up device from deep sleep by irq from touch panel, so kernel doesn't go to deep sleep when dt2w is active, I added parameter defining how long dt2w stays active after screen off. After this duration dt2w becomes inactive and kernel can go into deep sleep.
Sweep2Sleep
Swipe on navbar for screen off. Can be enabled by writing "1" into /sys/android_touch/sweep2sleep file. Disabled by default.
s2s_length: swipe length in dots. By default, equal to 25% of screen width.
init.d
For executing scripts at startup, put them in /system/etc/init.d folder and set permissions to 0755
Several scripts examples (doubletap2wake, sweep2sleep, fast_charge, gpu_undervolting): View attachment scripts.rar
Scores
For correct governors switching I recommend to use Kernel Adiutor
It also lets to manage IO schedulers, TCP congestion, fast charge, CPU undervolting.
Requirements:
Unlocked bootloader
TWRP
Installation:
Just install zip-archive from TWRP
Download:

Updates:
31.10.2016
CVE-2016-5195 "Dirty COW" fixed.
Now CPU voltage values take effect right after frequency changes.
30.07.2016
Adjusted voltages for overclocked frequencies due to cases of appearing stability issues on some devices.
15.05.2016
Removed GPU undervolting applying at booting due to some users had stability issues. Now for GPU undervolting use init.d script individually.
Adjusted governor thresholds.
Reduced min online CPUs from 3 to 2 when screen is on for stock pwrctrl_hotplug governor.

if someone want to set dt2w and s2s without init.d can use this apk made by Printusrzero http://forum.xda-developers.com/asc...ap-to-wake-t3036327/post62542196#post62542196
Thank you so much! I've been waiting for ages for a kernel which isn't only for emui 2.3
I'd installed kernel 5.1.1 ktuned on my P7 B852 and it's continuously restarts. Anyone had a kernel stock for TWRP?
What is your preferred setting?
Mine:
GOVERNOR: Impulse
CPU : maximum frequency 1596mhx
I/O : fiops with 128kb readahead
INTELLIPLUG :disabled
I discovered that with Intelliplug enabled, my phone has some glitches.....
With the settings above i get 50-60% battery when i go home, 8-10 pm
What are your settings ?

Someone else tried it on P7?
Installed with cwm on B861. Working, but I see no difference.
@Kostyan_nsk kernel comes overclocked, when I try to select the default clock and start the cell with the standard clock is not, always coming back to overclock, so I went back to stock kernel
@roxkiller, just set "Apply on boot" in Kernel Adiutor after limiting max. cpu frequency and enable Kernel Adiutor in Startup Manager, so KA will aplly your settings after reboot.
And btw, if you didn't notice, cpu voltage at 1996MHz is the same as at 1795MHz, therefore I doubt that power consumption will noticably increase relatively to 1795Mhz frequency...
I have set the cpu undervolting according to your recommandation. Today , i received a message on whattsap , when i picked up the phone to read it, the phone was already rebooting. It enter the system but saying no root available !!!
Rebooted the phone again, all ok.

It is not a recommendation, it's just my stable values as "play around" point.
@Kostyan_nsk it would be possible to compile a version without overclock ? I and perhaps most people do not like under / overclock the device, just heating up ... or pack the kernel to the option selected remain in next boot?
Kostyan what are you settings?
Updated version and details in first post.

+1
I really want to try it on my p7
As my memory serves me right, this issue was solved a few months ago. But you better have to ask P7 owners about it.
I thought the problem was solved for 720p but with 1080p there were still glitches?
720p never had glitches at all.

Weew... New Kernel For our beloved Yu Yureka..!
Dear S5 users,
I'm creating this thread for everyone who wants to share their kernel settings. My goal is to find the best (or at least, better) kernel settings in order to achieve the best S5's performance.
My S5 is a SM-G900F version and I'm using the Boeffla Kernel. So here's my current settings of my own created S POWER performance profile:
GOVERNOR/IO
governor = performance
scheduler = deadline / deadline
readahead buffer = 1024 / 1024
file system tweaks = ON / ON
CPU
cpu max frequency = 2841 MHz
cpu min frequency = 2841 MHz
hotplug settings = 4 cores min
cpu tweaks = OFF
cpu voltages = no undervolting
GPU
governor = performance
gpu max frequency = 578 MHz
gpu min frequency = 578 MHz
MISCELLANEOUS 1
charge rates = 0 / 0 / 0
swappiness overwrite = OFF
android low memory killer = 72 / 90 / 108 / 126 / 144 / 180
system tweaks = OFF
vnswap = ON (1000)
MISCELLANEOUS 2
tcp settings = westwood
modules = OFF / OFF / OFF / OFF / OFF
entropy settings = 256 / 320
logging = OFF / OFF
All the other tabs were left as they are, except the DISPLAY+LED tab that I made some adjustments but I think they don't affect the performance of the phone.
I use this profile (S POWER) only for benchmarks. I've also created another profile just for gaming (S BOOST). It has a lower max cpu frequency (about 2.6 GHz) in order to prevent random reboots during heavy games (maybe because of overheating/instability).
So I'm asking if there are better settings than those I use for S POWER. I think there's maybe some adjustments that can be made in the two MISCELLANEOUS tabs to raise the performance, but I don't really understand so much about parameters like "swappiness", "vnswap" or "entropy" values, so I just left them as they are.
Please post your settings and a screenshot of a recent AnTuTu's score (for example). Or at least, let's discuss about those specific parameters to find the best values (or at least, better).
Let's make the S5 (SM-G900F, for example) beat the 75.000 score mark in AnTuTu!
