m_plus kernel for Nexus 4 (mako)!
Hi all, since _motley has been MIA of late and his work was my favorite kernel for the Nexus 4, I have decided to continue his work in his absense. As a result much of this thread will look very similar to _motley's original thread here: http://forum.xda-developers.com/showthread.php?t=2021437. I would like to personally thank _motley for his work and dedication to this project, I only hope I can keep his loyal users happy in his absence.
Disclaimer: As usual, I am not responsible for anything that may or may not happen to your device as a result of using this kernel or any other flashable zips posted by me in this thread.
Features
Highly customizable with scripts. See post #2 for all the tuning options.
Google 3.4 base. All stock features are of course supported (camera, NFC etc.)
Compiler optimizations (-O2 + others) - using 2012.12 Linaro toolchain
Full ramdisk install with init.d support for stock/AOSP (CM already has support, for stock you must install busybox!)
CPU Overclock steps 1.56, 1.62, and 1.67GHz (default freq is still stock on boot, OC is optional)
304MHz lowest CPU freq step added with lower voltage than stock, since the device spends a lot of time at this frequency.
Safe UV by default for nominal, fast, and faster binned chips.
Voltage control - be careful to not save the setting on boot until you are 100% sure it is stable! (thanks faux123! + my tweaks)
In-kernel auto_hotplug (thanks to thalamus). I have added and exposed all the tuning parameters and a debug mode to userspace.
Customized in-kernel thermal solution smart scaling, dynamic polling, and configurable throttle temp.
Custom PowerHAL module (spam-free Android log from PowerHAL events)
Controllable touchboost frequency and duration
Gamma and Sound control (thanks faux123!)
Fsync control (3 modes)
USB Force Fast Charge
I/O schedulers - SIO(optimized), deadline (optimized), row, cfq, noop, and fiops
TCP Congestion Control (several choices available) - veno is the default
Governors - Interactive (default), OnDemand, PowerSave, Conservative
CIFS, NFS, NTFS r/w, TUN - built-in, no need for any kernel modules
Other misc patches and tweaks (see github link at the bottom of this post)
GPL compliant - source is kept up to date at github.com and released at the time the kernel is released to the public via this post. Demand that other devs do the same!
Requirements (please read carefully and visit the other dev threads as necessary)
Boot-loader must be unlocked and you must have a custom recovery installed (CWM or TWRP).
Have your ROM zip on your /sdcard so you can restore your whole ROM if necessary.
Do a complete backup using custom recovery so you can restore your boot.img and ROM if necessary!
System Tuner is recommended for monitoring/tuning the CPU, especially for voltage control. Other kernel apps like faux123's will likely work as well, but they have not been tested.
AOSP ROMs including stock - for init.d support, you must have a working busybox install in /system/xbin.
Installation
Check the requirements above and read release notes below for the build # you are installing for any extra instructions!
If coming from another kernel, read the instructions in red below and follow them before flashing.
Flash the the kernel zip using your custom recovery.
Optional: if you want to revert back to what you had, restore your backup of your boot.img in recovery. Another option for reset back to stock is to flash the stock reset zip above. For other custom ROMs, dirty flash your custom ROM in recovery to get your default kernel and ramdisk back.
If you have issues and are coming from another custom kernel or ROM, follow these instructions first before the install. Many custom kernels are changing the ramdisk or other binaries that require a reset before moving back to stock or another kernel.
Reset for Stock ROM - flash this reset package that includes the stock kernel, ramdisk, thermald, mpdecision, and PowerHAL binary. This can also be used if you are using the stock ROM and want to go back to stock.
Download - N4_422_stock_kernel_and_components.zip
MD5 - f801fc7702e29d85447e9b6fdc880549
Reset for any non-stock ROMs like CM, AOKP etc - dirty flash your current ROM or nightly zip then your gapps in recovery (just flash, no wiping). This will give you back your original ramdisk, kernel, and other binaries that other kernel devs may have tweaked, renamed, replaced etc.
Builds
Personal Request: If you plan to make unofficial builds with features not included in the builds posted by me, please don't link them in the thread, all this does is result in confusion especially if someone has a problem with something you have added, it is much easier for me to provide support if I know that everyone in the thread is running the same builds I am. If you want to make a kernel with these features, feel free to start another thread so that they can be discussed and supported as appropriate.
Current Buildbot Status:
Source: https://github.com/thracemerin/kernel-Nexus4
As with _motley's builds, the stable version will be a base build which includes the ramdisk and other component binaries to make the kernel work as expected, you will need to flash the stable version prior to flashing any experimental versions or something may not work as expected.
All files are now available from goo.im: http://goo.im/devs/thracemerin/mako/m_plus
Note: Due to goo.im file naming rules I had to change the name of the zip to m_plus from m+, this has no effect on the content, the ones on goo.im are identical to those that were on dev-host other than the names.
Change Logs
Note: The builds below are for 4.2.2 only, for the latest 4.3 alpha builds check the last few pages of the thread. *4.3 builds will appear on goo.im when they are closer to being official production builds.
This thread is for 4.2.X versions only, use the following threads for 4.3:

Build 8 (Exp) - June 18, 2013
Note: You must be on Build 1 or later.
Reverted some of the msm_hsic patches because they seem to cause data drops
Now build with the Linaro 4.8.2.2013.06 toolchain
Switched the allocator from SLUB to SLAB because SLUB wouldn't boot when compiled with 4.8
Various fixes to allow building with 4.8
Build 7 (Exp) - May 26, 2013

Patches to freezer from Colin Cross
More patches to workqueue from CAF
Patches to the cpufreq driver from CAF
Reverted lowest frequency step to 384MHz (See Post 3 for why)
Fixed board-mako-regulator.c to allow for UV to work (Warning: Reset your UV settings if you have UV below 850mV, if you flashed the previous alphas this is probably not necessary.)
Reset undervolting to stock from Google, just in case the above causes problems for new adopters (You still have full access to undervolt to 600mV if your chip can handle it)
Added the change pointed out by veyka here: http://forum.xda-developers.com/showpost.php?p=41730297&postcount=380

Patches to android lowmemory killer from CAF
Headphone poweramp controls (thanks to Faux123)
Build 3 (Exp) - May 3, 2013
Note: You must be on Build 1 or later.
Various sched patches that were in _motley's 4.2.1 kernel and not his 4.2.2 kernel
FIOPS i/o scheduler is back
192mhz frequency step added (thanks to showp1984)
Note: The ramdisk currently forces the minimum to 304mhz so i added an init.d script to force it to 192mhz so I didn't have to redo the ramdisk.
I'll fix this in the next base build.
If you still want to use 304mhz as your lowest step, see post 3 for details on how to do this.
Note 2: The voltage is the same as the one _motley used for 304mhz for stability reasons, it will still use less power, but feel free to uV it if you like.
Build 2 (Exp) - April 30, 2013
Note: You must be on Build 1 or later.
Update ROW i/o scheduler to the latest from CAF, now default i/o scheduler
FIOPS i/o scheduler was removed because _motley added FIOPS and ROW as 1 commit and messing with ROW screwed it up.
Hardcode ROW magic values (thanks to franciscofranco & osm0sis)
Update interactive governor to the latest from CAF (it may be a little less aggressive)
Krait Retention (thanks to CAF, faux123)
Build 1 (Base) - April 29, 2013
Everything from _motley's b49 build up to this point.
Built with the linaro 2013.04 gcc-4.7 toolchain
Thanks
Google - For AOSP sources
LG - for building the N4
Qualcomm/CAF - for their updates to the N4 kernel
_motley - for all his work on this kernel

anyone else i've neglected to include, if you feel you deserve to be thanked by name by all means PM me
Tunables should be the same as _motley's kernel so I'm quoting him here:
(All the tunables that are discussed in _motley's thread http://forum.xda-developers.com/showthread.php?t=2021437 should work the same way on this kernel)

Setting custom RGB color settings via sysfs
This can be done from the adb shell on your PC, or any terminal app. If you change them, they will not persist after a reboot. However, you can set them in an init.d script if you found another color combination that you like better than the one I have used.
Code:
echo "255 255 255" > /sys/devices/platform/kcal_ctrl.0/kcal
echo 1 > /sys/devices/platform/kcal_ctrl.0/kcal_ctrl
Command 1 sets the color and Command 2 commits them. Stock is 255 255 255.
Setting custom Gamma settings via sysfs - Exp kernel build 31+ only - thanks to faux for sharing his code
Warning: changing these values can be potentially be dangerous to your display if you make a mistake. For those that feel comfortable with what they are doing and want to experiment, please report back and share your findings.
Important, please read!
There are ten digits in the string separated by one space
First digit is a checksum and is never stored. The checksum is simply the sum of the other 9 numbers. This is to make it harder to so the interface is respected and you are forced to think about what you are doing.
There are 3 sysfs interfaces for gamma, one for each color:
Code:
#!/system/bin/sh
# Show the current configuration and the checksum
cat /sys/devices/platform/mipi_lgit.1537/kgamma_red
cat /sys/devices/platform/mipi_lgit.1537/kgamma_green
cat /sys/devices/platform/mipi_lgit.1537/kgamma_blue
Update:
Recently molesarecoming started opening this up and showing us what the values can be used to adjust. Franco then suggested that the white and grays should be swapped in moles original work. So, for init.d values using this interface, we have the following "banks" if values if we agree with Franco on the swap of the whites and grays.
Code:
R: checksum, g_white, g_mids, g_black, 0, g_contrast, g_brightness, g_saturation, g_grey, 2
G: checksum, g_white, g_mids, g_black, 0, g_contrast, g_brightness, g_saturation, g_grey, 2
B: checksum, g_white, g_mids, g_black, 0, g_contrast, g_brightness, g_saturation, g_grey, 2
(the zero in position 5's and the 2's in position 10 are recommended to be left alone since they are currently unknowns)
Minus the checksum, the 27 values mirror the 3 color arrays (3 x 9 = 27) in the actual LG LCD driver. Minus the unknowns, we are left with 21 values. Note that every one of the variables can have their value tweaked by color (saturation for red, saturation for green etc.), however, it is recommended that you start with all the values of one type being the same and then tweak from there if you really want to fine tune.
You have a lot of power in your hands even without fine tuning. Many will argue that fine tuning isn't required. If you look at the stock settings by Google in post 2, they took advantage of fine tuning for whatever reason. Even though many don't like these settings by Google, it shows how flexible the interface can be.
Instructions:
1) Start with a preset config (LG or Google) as shown further below. This is a set of 3 lines, 10 numbers for each line.
2) Tweak columns for their values as above. For example, we tweak contrast and brightness as in faux's original app. We could also do the same for saturation, blacks, whites, grays etc.
Example: start with LG presets with numbers to adjust:
383 114 21 118 0 10 4 80 48 2
383 114 21 118 0 7 4 80 48 2
383 114 21 118 0 5 1 80 48 2
3) Now update the checksum in column 1 (first digit = sum of last 9 digits)
397 114 21 118 0 10 4 80 48 2
394 114 21 118 0 7 4 80 48 2
389 114 21 118 0 5 1 80 48 2
4) Create a script inside a text file - my recommendation for your first test
Code:
#!/system/bin/sh
# Set data color pro presets from shared Google spreadsheet (thanks user acer73!)
# Use LG presents as your starting values and then adjust columns 6 & 7 from the spreadsheet
echo "397 114 21 118 0 10 4 80 48 2" > /sys/devices/platform/mipi_lgit.1537/kgamma_red
echo "394 114 21 118 0 7 4 80 48 2" > /sys/devices/platform/mipi_lgit.1537/kgamma_green
echo "389 114 21 118 0 5 1 80 48 2" > /sys/devices/platform/mipi_lgit.1537/kgamma_blue
#Set the complimentary RGB values for this calibration
echo "248 248 248" > /sys/devices/platform/kcal_ctrl.0/kcal
echo 1 > /sys/devices/platform/kcal_ctrl.0/kcal_ctrl
5) Run the script (or you can echo each line manually to test from adb if you prefer).
6) Turn the screen off and on for the gamma change to take effect.
7) Check the dmesg output for any clues and to see the output of the result.
8) Place the script into your /system/etc/init.d/ folder (or equivalent) for a permanent color change!
Screen refresh (added in b37) - this should only be called by apps or scripts while adjusting and testing colors "live" with the motley or faux sysfs interface. It should NOT be implemented on startup via init.d or by apps since it will compete with the normal power on process.
Code:
echo 1 > /sys/devices/platform/mipi_lgit.1537/refresh_screen
Presets:
Code:
#!/system/bin/sh
# Set LG presets (motley stock) - i.e. popular partial revert of Google's tweaks just before release
echo "383 114 21 118 0 0 0 80 48 2" > /sys/devices/platform/mipi_lgit.1537/kgamma_red
echo "383 114 21 118 0 0 0 80 48 2" > /sys/devices/platform/mipi_lgit.1537/kgamma_green
echo "383 114 21 118 0 0 0 80 48 2" > /sys/devices/platform/mipi_lgit.1537/kgamma_blue
Code:
#!/system/bin/sh
# Set stock Google presets (from kernel source code)
echo "332 64 68 118 1 0 0 48 32 1" > /sys/devices/platform/mipi_lgit.1537/kgamma_red
echo "332 64 68 118 1 0 0 48 32 1" > /sys/devices/platform/mipi_lgit.1537/kgamma_green
echo "364 32 35 116 0 31 16 80 51 3" > /sys/devices/platform/mipi_lgit.1537/kgamma_blue

FSYNC Control
Notes: I thought about combining these options, but many kernel apps already support these two options. So, I have them both and they can be controlled in combination to give us the 3 modes. If you set fsync_enabled = 0 it will be OFF regardless of how Dyn_fsync_active is set.
3 Modes:
Dynamic (default in b35 and higher)- fsync is asynchronous when screen is on, when screen is off it is committed synchronously
dynamic fsync ON
fsync ON
Code:
echo 1 > /sys/kernel/dyn_fsync/Dyn_fsync_active
echo 1 > /sys/class/misc/fsynccontrol/fsync_enabled
Off (best performance, less safe) - fsync is always asynchronous (b32 and prior builds)
dynamic fsync OFF
fsync OFF
Code:
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
echo 0 > /sys/class/misc/fsynccontrol/fsync_enabled
Stock (safest) - fsync is always committed synchronously
dynamic fsync OFF
fsync ON
Code:
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
echo 1 > /sys/class/misc/fsynccontrol/fsync_enabled
There is a lot of info out there on fsync, that will not be discussed here. I have run fsync off on several devices for awhile now and haven't experienced any issues. If you are using a device that is not stable and crashes alot, I recommend enabling it via init.d or script manager on boot. Hopefully your N4 is as stable as is mine.
USB Force Fast Charge
You can turn it on with popular apps (like Trickster MOD) that support the common sysfs toggle as shown below.
If you don't like it or don't want to use it, it is off by default.
Turn ON:
Code:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
Turn OFF:
Code:
echo 0 > /sys/kernel/fast_charge/force_fast_charge
Notes:
When it is ON, you will not be able to connect your phone to your PC (adb, mtp etc.). This is expected behavior.
To start charging: turn fast charge ON, plug the USB cable into your PC, and charge up.
To stop charging: unplug the USB cable and turn fast charge OFF. Now you can plug back into your PC for normal trickle charging, adb/mtp etc.
Tip: if you see it connect to your PC (media device or adb), it isn't working. Unplug the cable, wait a couple seconds and plug it in again.
Boostpulse control - Experimental build only
Trickster MOD works great to play with these.
How long does it boost when Android senses touch? (in b10 and b14 it is above_hispeed_delay)
Code:
/sys/devices/system/cpu/cpufreq/interactive/boostpulse_duration
What freq does it boost to?
Code:
/sys/devices/system/cpu/cpufreq/interactive/hispeed_freq
Turn touchboost OFF/ON (in b10 and b14 only)
Code:
/sys/devices/system/cpu/cpufreq/interactive/input_boost
Thermal Throttling and Hotplug Control - Experimental build only
Warning: these do not have to be changed from the defaults and could potentially be dangerous if you make a mistake. For those that know what they are doing and want to experiment with settings, scripts etc. please report back your findings.
msm_thermal:
Throttle temp in C. Default is 70, valid range is 45 to 80 (recommend to not go over 75):
Code:
/sys/module/msm_thermal/parameters/throttle_temp
Minimum freq used in throttle down before returning to max, default is 7 = 1.13GHz. Range is 4 to 8 (810Mhz to 1.24GHz)
This is the index in the frequency table as seen in Trickster MOD, System Tuner etc. It is zero based (i.e. 304MHz is zero).
Code:
/sys/module/msm_thermal/parameters/min_freq_index
Turn on thermal debugging so you can see what is happening in the kernel log:
Code:
/sys/module/msm_thermal/parameters/thermal_debug
auto_hotplug:
Load based hotplugging parameters. I have taken _thalamus' base (thanks!) and have exposed most of the tuning parameters to userspace.
Turn off/on hot_plug debugging Y/N, default N, this spams the kernel log like crazy, turn on only when troubleshooting/testing
Code:
/sys/module/auto_hotplug/parameters/debug
Load at which a CPU is taken offline, 40-125, default 80:
Code:
/sys/module/auto_hotplug/parameters/disable_load_threshold
Load at which an extra CPU is put online, 130-250, default 200:
Code:
/sys/module/auto_hotplug/parameters/enable_load_threshold
Load at which all CPU's are enabled, 270-550, default is 400 (or 100 x number of cores):
Code:
/sys/module/auto_hotplug/parameters/enable_all_load_threshold
Sample rate in milliseconds, converted to jiffies at runtime, 10-50ms, default 20:
Code:
/sys/module/auto_hotplug/parameters/min_sampling_rate
Number of samples in the circular buffer, 5-50, default 10 (more samples = less aggressive; less samples = more aggressive):
Code:
/sys/module/auto_hotplug/parameters/sampling_periods
Maximum number of cores online (regardless of load) when screen is on, 1-4, default 4 (tune down for battery savings):
Code:
/sys/module/auto_hotplug/parameters/max_online_cpus
Minimum number of cores online (regardless of load) when screen is on, 1-4, default 1 (tune up for performance/bench-marking):
Code:
/sys/module/auto_hotplug/parameters/min_online_cpus
Vibration Intensity
You can also use Trickster MOD to set this.
Example increase intensity:
Code:
echo "90" > /sys/class/timed_output/vibrator/amp
To go back to stock:
Code:
echo "70" > /sys/class/timed_output/vibrator/amp
Why are the base voltage tables different on some phones
What CPU do you have? Nominal, Fast, Faster ...or Slow
The phones with the lower default voltage values use the "fast" or "faster" frequency table, consider yourself lucky. This explains why some can't UV as much as others since they are starting with lower mV's to start. These are built in factory tolerances that depend upon the binning of your chip. I am familiar with the same thing in the tegra3 world where I have had more experience. So, don't worry as this is commonly done in this industry. Hopefully folks don't go freaking out because they have a nominal chip like I do. It's probably good for a dev to have a nominal chip so we can better honor the limits.
http://en.wikipedia.org/wiki/Product_binning
How do I tell what I have?
If you boot up your phone fresh and look at the dmesg output (kernel log) while the messages are still there, you will find one of the following output messages where it selects it's frequency plan depending on the binning of the chip.
Code:
adb shell dmesg | grep PVS
acpuclk-8064 acpuclk-8064: ACPU PVS: Nominal
-or-
acpuclk-8064 acpuclk-8064: ACPU PVS: Fast
-or-
acpuclk-8064 acpuclk-8064: ACPU PVS: Faster
-or-
acpuclk-8064 acpuclk-8064: ACPU PVS: Slow
I have tweaked all the frequency tables nominal, fast, and faster (as well as slow to compensate for the lower freq) to keep them similarly scaled relative to stock. If you don't like the safe defaults (already UV'ed), then use voltage control and come up with your own preferred values.

Frequently Asked Questions
Q: You gave us 192Mhz, now you removed it and set 304Mhz back to 384Mhz, why?
A: Good question, there had always been some speculation in this thread and others that frequencies below 384Mhz were not in fact being set correctly, show-p1984 managed to run his device at 27Mhz with no stability issues (this should be impossible) so we did some quick and rather unscientific benchmarking in this thread and found that there didn't seem to be any difference in CPU performance between 192Mhz and 304Mhz (and there should have been), I then speculated that 304Mhz was also not being set, after a little more unscientific benchmarking I determined that there was no difference in performance from 304Mhz to 384Mhz either, so based on this I don't see any reason to allow these frequencies.
Q: I don't want to use the 192mhz frequency, how can I disable it? (Build 3-6)
A: One of the four options below will fix it:
You can delete my script, it's located at /system/etc/init.d/01cpu and reboot, this will set you back to 304mhz minimum.
You can remove it from the zip file (same location in the zip hierarchy) before you flash.
You can use your favorite kernel tuner (trickster, fauxclock, etc...) to switch the minimum frequency back to 304mhz and set it on boot.
You can change the /system/etc/init.d/01cpu script to set whatever minimum frequency you want (it has to be a valid one from the table)
Q: If the 192mhz and 304mhz steps use the same undervolt settings, how can 192mhz use less power?
A: The formula for power consumption is: P = f * c * V ^ 2
Where: P = power consumption, f = frequency, c = capacitance and V = voltage
So: since c is constant in this case, and we'll assume you've used the lowest UV possible (600mV)
At 304mhz: P = 304 * c * 600 ^ 2
At 192mhz: P = 192 * c * 600 ^ 2
This means that 304mhz uses approximately 1.58 times more power than 192mhz over the same time.
Q: There are a bunch of fixes for the delayed notification issues in various threads, what should the settings be for this kernel?
A: The following values should be set in your /system/etc/wifi/WNCSS_qcom_cfg.ini (depending on your ROM you may have different values), these are the Google stock values and appropriate for this kernel.
Code:
McastBcastFilter=3
HostArpOffload=0
gEnableSuspend=3
You can set these values by flashing this: wlan_revert.zip - MD5 - 381013687035626bcb1cbaf609ea4311
Q: Does this kernel include the ARP offload patch?
A: No, and for those of you following my other thread here: http://forum.xda-developers.com/showthread.php?t=2102986 you will know that there is an issue where our WiFi chip responds to ARP requests with a bad MAC address during deep sleep, this results in problems with direct connect (WiFi direct, AirDroid, etc...) and can cause issues with certain types of routers and networks that do not cache ARP addresses for long, as a result I no longer use it in my other kernel either. I am using a different solution which solves the problem for me and many others but has a slight battery life hit, I will post a flashable zip to modify the binaries to include this fix at a later time, but for now if you wish to include this fix do the following.
Code:
open /system/etc/wifi/WNCSS_qcom_cfg.ini in your favorite file editor
find the line that currently reads gEnableSuspend=3
change the line to read gEnableSuspend=2
save the file
reboot your device.
Q: I flashed this kernel and my battery life sucks! WTF?
A: Clearly I didn't design this kernel to drain your battery (nor did _motley) and in my experience most battery drain issues are app related and not kernel related. In order to help me help you solve the problem, please download Better Battery Stats either from the Play Store (costs money, but I strongly encourage supporting the dev) or the free version from XDA and provide me with a dump file for a few hours of use so I can see what is going on with your device, if you don't do this I will assume the battery drain is your fault and will ignore your complaint.
Q: Can you add feature x from kernel y?
A: Maybe, I'm not going to take this kernel and stuff it full of every single idea anyone has while lying in bed trying to fall asleep, but if the feature seems like something that most would use and it's in a reasonable state of working (ie. not something that someone else just started working on) then I will consider adding it, absolutely no promises in this regard.
Q: I got a random reboot, SOD, other bug that must be kernel related, what do I do?
A: Provide me with appropriate logs (dmesg, logcat, last_kmsg (see my sig)) and instructions on how you caused this if possible, if I can't reproduce the issue and I can't see it in the logs there is nothing I can do. Be as detailed about what you were doing at the time it happened, more information is always better than less.
Q: If _motley comes back what will happen with this project?
A: Well, I don't want to step on any toes here, this was originally _motley's work, what happens to it long term if he returns will ultimately be up to him. If he wants to continue from where he left off and merge his own changes beyond b49, I may keep going as a separate project, if he wants to fork me and continue from the point I'm at when he returns that's ok with me too and I'd probably stop if that were the case, but we're speaking in hypotheticals here, anything is possible.
Q: Touch control doesn't work! Why not?
A: Touch control requires a module that is compiled by the author and provided as a pre-compiled binary. I'm not specifically looking to break it's functionality, but changes I make may cause it to stop working at any time between releases, the only way to get this fixed is to speak to the author of the addon and have him recompile the module. If he needs my assistance with anything specific to this kernel, I will do my best to help him out.

I hope _motley is alright. Thank you for continuing to develop this great kernel in his absence.
Will you be including the new Prima drivers and retention patches introduced by kszaq to fix some of the wifi problems? I know it's not a solution for everyone, but I personally thought it worked well with no battery hit and some others seem to agree.
Anyway, thank you for your work and good luck with _m+ .

Krait retention, yes.
Prima/ARP Offload, not right now, there is a workaround and better explanation for why in post 3, I'll continue to work on it in my other thread, if I get to a fully working solution, then absolutely. The current issue with the Prima driver makes my phone unusable for something I do on a daily basis which is why I will not do it currently (I want to be able to use this kernel as my daily driver).
Flashed the CM build, all fine thanks! Felt the smoothness of Motleys kernel again.
Very nice! Um, I took a look at your git, but i couldn't work out what you added over b49 heh, mind giving a quick summery?

Nothing atm, this release was just a stable start to move forward on and proof that I had the infrastructure set up to actually build with linaro gcc-4.7. I'll have another release in a day or two with some new stuff
Plus, it avoids having to get people to get b37 & b49 from _motley's thread before moving forward with builds here.

It's 600mV right now, correct?
Yup, it's 600mv now. I was thinking that since the phone spends most of its time at 384mhz, and for me that frequency is totally stable at 600mv, it's probably possible that the voltage at 384mhz can go even lower. However I noticed that most of the other kernels have higher minimum allowed voltages, so there may be a reason for that that I'm not seeing here.

READ THIS: READ BEFORE YOU ASK and HELP TO KEEP THIS THREAD MORE CLEAN! BUT ALSO BETTER ASK ONCE MORE BEFORE YOU MESS UP YOUR PHONE! If you find something missing in this OP/FAQ, please PM me and I will add it. Thank you!
This is a custom kernel mostly based on Motorola's 3.0.8 Hybrid Kernel which was initiated first by the STS-Dev-Team (Hashcode, Dhacker).
I created this kernel for my main goal: BATTERY LIFE! Like many other custom kernels this one also supports several performance related features like OVERCLOCKING, UNDERVOLTUNG, GPU CONTROL, CPU OPTIONS, RAM TWEAKS, etc etc... But my main goal was not to bring up a kernel which is fast as hell - I want to bring up a kernel that is fast + a long lasting battery! Many custom kernels are also very fast but they don't save battery. JBX-Kernel is supposed to push your device to great speed while being on low power settings. I hope you enjoy it!
If you want to support me and my work just leave me a beer.
You can find the FAQ at the bottom of this post!

Support for Trickster Mod Kernel Control App (Download from Gplay)
*]Too much stuff to list here. See "Sources" below and check my Github
* HTC's Asynchronous Fsync and Dynamic Fsync:
Asynchronous fsync (called "afsync" or "async fsync") from HTC is ported into this kernel. By default it's enabled and dynamic fsync is disabled (and as well it isn't needed anymore). But just to test a little bit around to see which one of both features is the better one - for battery & performance. But currently Tricktser Mod doesn't support a toggle for afsync, so I had to find another way to use Trckster. Finally I did it like this:
The dynamic fsync toggle in Trickster Mod is now serving both functions - the dynamic fsync AND the asynchronous fsync! How? By default Dynamic Fsync is disabled, and Afsync is enabled. If you now enable Dynamic fsync using the toggle, Afsync will be automatically disabled, so both functions are not conflicting each other - and this way we have a working toggle for both of them.
CAUTION
This is a work in progress! Some of the current features are still not in final stat. If you are facing issues report back here and DON'T spam the threads of the rom you're using!
Be careful with some settings such like Voltage and Overclocking!!! If you aren't experienced with these things, dont play with 'em!

2. Issues
1.1 How can I change the smartreflex minimum/maximum voltage
What is Smartreflex?
SR is compareable with an CPU governor but not for scaling frequencies but for voltages. That means SR has a fixed range of voltage (min/max) and calculates the optimal voltage for each CPU frequency. In example on light use of the CPU it scales down to lower voltage - on heavy use it can sclae to higher voltage. This is an efficient system to save power! Compared to EMIF which uses the hardcoded voltages it saves more power because it's variable. EMIF cannot vary between the values.
This interface has a hardcoded range of 830mV min to 1450mV max. Usually there is no need to adjust these values but irt can be usefull in example when using high overclocked frequencies above 1,5ghz! Usually SR cannot handle frequencies above 1,5ghz and I have hardcoded the maximum range of 1,45mV which should allow SR to handle it. In prior times the users had to turn off SR when OCing above 1,5ghz which causes the CPU to eat more power. But you can try around and report your results.
CAUTION: Don't raise the maximum SR voltage too high! It can burn your board = no phone anymore! I recommend to not use higher values than 1490mV! As already mentioned: THe default value should be enough!
ANd also: USUALLY THERE IS NO NEED TO CHANGE ANYTHING ON SR! IF YOU DON'T KNOW WHAT YOU'RE DOING, PLEASE LEAVE IT ALONE!
Ok, now let's see how to do this:
Turn ON/OFF SR
1. Open Trickster Mod
2. Head to the "Specific section"
3. Scroll down to "Smartreflex"
4. You can toggle ON/OFF SR for each component (IVA, CORE, MPU)
Usually I recommend to keep SR ON because it saves power! But in some cases when overclocking the CPU (MPU) the device could freeze - whether you OCed too much or SR couldn't handle the frequency! In this case you can try to raise the vmax value of SR a little bit (CAREFULLY!) and try again. If it sitll freezes and you're sure that you didn't OC too much, turn SR OFF at least for MPU!
Maximum Voltage
Currently there is no app which supports the feature of adjusting the SR vmax value, because I wrote this feature some days ago.
But in the next Trickster Mod version this option will be supported!
example:
# To read the current vmax value. Replace XXX with one of the following:
sc_core - for core max sr voltage
sr_iva - for iva max sr voltage
sr_mpu - for mpu max sr voltage (mpu is most related for CPU scaling)
cat /sys/kernel/debug/smartreflex/XXX/vmax
# You will get an output, e.g. for mpu = 1450000 (1450mV)
# To set a new value, do the following command (replace XXX with a value like above - BE CAREFUL! USUALLY THE DEFAULT VALUE ENOUGH AND YOU CAN LEAVE IT UNTOUCHED!)
echo XXX > /sys/kernel/debug/smartreflex/XXX/vmax
Minimum Voltage
It's easy because Trickster Mod supports it!
1. Open Trickster Mod
2. Head to the "Specific section"
3. Scroll down to "Smartreflex"
4. Below each SR component (IVA, CORE, MPU) there is displayed a value (usually 830 default) which means this is the lowest scalable voltage for this component. You can try to decrease this value for the case you want to UV a bit more - or raise it a bit for the case you think that the set range is too low and causes freezes on your device.
1.2 How do I use Live OC (Live OVerclock)?
This feature allows you to overclock the CPU in realtime. It works with a multiplier value set by the user. The default multplier value is "100", which means: No OC! If you want to raise the OC frerquency, just raise this value step by step.
FOr my device the maximum working OC value is "111" which means the maximum frequency is running at 1498mhz!
NOTE: Keep in mind that you tunr Smartreflex OFF for higher freqs than 1500mhz - or raise the maximum SR voltage range for "MPU" a little bit and test if it works.
Ok, how to use Live oC in action:
Open Trickster Mod App and swipe to the tab "Specific". There you will find something like this:
Code:
MPU OC [100]
DON'T TOUCH THE "CORE OC" SECTION, IT WILL CAUSE FREEZES!
Now slowly increase the value "100" to something higher, e.g. "105". Tap the hook in the right upper corner to confirm. To see your new set of frequencies you can now whether close and restart Trickster Mod or just use any monitoring app like Cool Tool which will show your frequencies in real time. That's it!
CAUTION: You can damage your phone forever!!!! This feature allows you to set very high frequencies (also up to 2,0ghz...) - That DOESN'T mean that your phone can run these frequencies!
If your phone freezes or crashes you have probably set too high OC - or your voltage is too low.
1.3 How do I use Custom Voltage (EMIF)?
NOTE: This only adjusts the fixed voltage! When you have Smartreflex ON it can still vary! You have to see the bigger picture: This voltage value sets the "middle point" for voltages. Smartreflex is still able to increase or decrease the voltage. When Smartreflex is OFF the CPU will stay on this voltage you set here and probably eats also more power.
How does EMIF works together with Smartreflex:
Code:
-------
| CPU |
-------
|
------------------ ------------------
|Voltage 1015 mV | ---->| SMARTREFLEX ON| = 1015mV +/- "vmax"/"vmin"
------------------ -------------------
|
--------------------
|SMARTREFLEX OFF| ----> 1015mV FIXED! No changes!
-------------------
Thi smeans if you change the voltage for a scaling step (OPP) while SR is ON, SR will adjust the voltage from this value, means: mV-Value +/- SR vmin/vmax. WHen SR is OFF it will stay on this mV as a fixed value.
How to adjust the voltage?
Well, this feature can be used with all generic apps which are supporting voltage settings. But we are prepared well, you can adjust voltages also with the "Trickster Mod App".
When you open the app, head to the tab "Specific" and below the "Live OC Section" you will find your voltage table, which looks like this:
Code:
<-->
1200 [1398]
1000 [1388]
900 [1371]
...
..
..
Now just tap the arrows in the right upper above the first voltage value and just type or tap (per direction) a value, e.g. "-25". To apply it, confirm by tapping the hook in the right upper corner of your screen. That's it, your new voltage values are now set and applied. And also mind here: If your phone freezes you porbably have set it too low.
CAUTION: NEVER SET HIGHER VOLTAGE THAN 1490mv here!!!!! Or you might damage your phone FOREVER!
This voltage is not the same like Smartreflex! But it's still voltage! Just be carefull!!
1.4 How can I use GPU OC and GPU Governor?
GPU Overclock doesn't work like Live OC! You cannot really set custom frequencies for the GPU, but you can select and set the maximum frequency from a hardcoded range!
For the GPU there are the following available frequencies:
154mhz (FIXED!)
307mhz
384mhz
416mhz
The minimum frequency of 154 is FIXED! This means you cannot change it because the GPU needs a minimum speed to run with. But the kernel allows you to select the maximum speed. This can be usefull for playing games and also for saving power . In example when not playing games you don't need the GPU to run at 416mhz! Set it to 307mhz in this case and save power.
When you open Trcikster Mod and head to the "specific section tab", you will find "GPU MAX FREQUENCY" and it's currently set maximum frequency. Tap on it to select your preferred one:
- 154 Mhz
- 307 MHz
- 384 MHz
That's it. The new setting will be your new maximum GPU frequency.
Below there's another option called "GPU Governor". Just tap on it and select your prefered one.
NOTE: If you want to track current GPU frequencies and watch governor's behavior, just switch to Trickster's "Informations" - Tab and watch the frequencies clock.
1.5 How can I use Gamma Control?
What is gamma? The gamma setting sets the color range for the screen. You can compare it to the contrast. We all know that the touchscreen eats most of the power compaerd to all other components in a smartphone! A lower brightness causes less power consumption and a lower gamma or contrast range alos helps a little bit to save power.
In this kernel you can choose from a range of "5 - 10" while "5" is very bright while "10" is very dark. The default setting is "5" BUT CAUTION: Trickster Mod will display a range of "0" to "10" and the default setting will be shown as "0". This is caused by the fact that this feature was ported from the Gnex device where you can choose from a higher range. The only sideeffect is that the values "0" - "5" won't show any difference.
How to set the gamma value?
Well, once again open Trickster Mod and swipe to the tab on the right end. Just select your preferred value by using the slider.
Alternately you can use sysfs by terminal or adb:
OMAP Gamma interface:
echo i > /sys/devices/platform/omapdss/manager0/gamma
Replace i with 0-10 of your choice.
1.6 What is "Battery Friend and how to use it?
Battery Friend is a simple toggle (ON/OFF) which sets your device into a battery friendly mode without the need to play with all settings in Trickster Mod /sysfs until you find a good setting. In fact it does the job for you.
What does it affect?
NOTE: Doesn't lock anyx frequencies anymore!
locks dynamic Fsync enabled
locks Fsync disabled
Doesn't allow any OC (Live OC will not have any effect, Core OC is not allowed in this kernel)
Increases the dirty ratio interval to 90% (starts working at this value)
Enables Dynamic Hotplug: This doesn't allow hotplugging during device is active - and it will always turn CPU1 OFF during suspend! It also prevents from conflicts when user uses a hotplug governor (which isn't a good idea though) - but hotplug governors are causing higher battery drain!
Dynamic Page-writeback always enabled
How to toggle Battery Friend:
For now the only way is via terminal, adb shell or root explorer (text editor)
For terminal and adb:
Code:
echo 1 > sys/kernel/battery_friend/battery_friend_active /* Enable */
echo 0 > sys/kernel/battery_friend/battery_friend_active /* Disable */
For Root Explorer
Open Root Explorer
Navigate to sys/kernel/battery_friend/
Open "battery_friend_active" with Text Editor

1.7 Suspend Governor Control (CURRENTLY DISABLED)
Suspend Governor Control is a kernel module written by me. You can use it to set your preferred Screen-Off-governor.
For now it's only supported by sysfs (Trickster Mod will support all my current and upcoming features as soon as it gets updated with its new UI mode!
How to set suspend governor
Open a terminal or use adb shell
Code:
su
echo "x" > /sys/kernel/suspend_gov/suspend_gov
Replace x with one of these values:
0 = Ondemand
1 = Ktoonservative
2 = Conservative
3 = OndemandX
NOTE: No matter what governor you use for suspend mode, if Battery Friend is enabled the second core will be turned off during suspend!
1.8 IVA Overclock
What is IVA OC?
IVA OPPs are controlling the CPU load for sound events. It could be useful (in some cases) when you get sound related laggs. Just set the maximum frequency to highspeed. This will allow more CPU power for sound events but also will cause higher battery consumption.
How to use IVA OC?
If you want to check the current IVA frequency. Just type in Terminal or ADB:
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/iva_clock
You will get an output like this:
Code:
132 Mhz
2. You can whether enable IVA highspeed: 130 - 430 Mhz ["1"] or enable IVA normal speed: 130 - 332 Mhz ["0"]
320 Mhz max: echo "0" > sys/devices/system/cpu/cpu0/cpufreq/iva_freq_oc
430 Mhz max: echo "1" > sys/devices/system/cpu/cpu0/cpufreq/iva_freq_oc
1.9 DPLL Cascading
DPLL: Davis–Putnam–Logemann–Loveland (DPLL) algorithm
To get more info about this please see wiki
But to sum it up shortly: It helps to use/stream media (music) in a low power mode.
NOTE: DPLL Cascading will be available to be switched easily via Trickster Mod App soon!
How to switch DPLL?
DPLL is ENABLED by default!
Open Trickster Mod -> Speicific Tab --> DPLL (soon)
sysfs:
Turn off:
Code:
echo 0 > /sys/kernel/dpll/dpll_active
Turn on:
Code:
echo 1 > /sys/kernel/dpll/dpll_active
1.10 HDMI toggle
Some users are facing a RAZR-sepcific problem: HDMI cable is detected, even though there is no cable plugged!
Therefor I included a toggle to switch HDMI wether ON or OFF. Additinally there's an init.d script included within the AROMA Installer you can select during the installation of JBX-Kernel.
To enable/disable HDMI on-the-fy:
sysfs:
Turn off:
Code:
echo 0 > /sys/kernel/hdmi/hdmi_active
Turn on:
Code:
echo 1 > /sys/kernel/hdmi/hdmi_active
1.11 Intelli-Plug
For intelli-plug hotplugging is now only allowed when the device enters sleep.
To enable hotplugging universally just change the value of the following entry whether to 1 (on) or 0 (off):
Code:
sys/module/intelli-plug/parameters/int_hotplug
2. If anyone has the following issues:
Issue
Media Process FC
No SD-Card in File Explorer
My CPU Settings (frequencies, etc) won't be saved (it sets itself back to Kernel default after screen off)
My phone freezes/reboots always when I try to set options in Trickster Mod
The device is lagging very hard
Solution
Media FC: Open App settings, head to "Download Manager" and "Media Storage" and hit the "delete data" button. Reboot. Now it shouldn't give any FCs anymore and after a little bit of waiting it will find all Media (Pictures, Videos, etc..)
No SD-Card: Reboot into recovery, go to "Mounts & Storage", tick "mount int" or "mount ext".
USB: Make sure the screen is ON while plugging the cable in.
CPU Settings: This is a bug which cannot be solved at the moment. Temporary solution: In Trickster Mod just activate the "Frequency Lock" and your settings will persist.
Trickster Mod:: Open App settings, Trickster Mod and select "uninstal updates". Now it should work.
Crashes, Freezes, lagging, something doesn't work, etc
There are too many reasons which could cause crashes! So here is a checklist for you to look for. Check each point and try the following workaround:
- Your rom has CPU tweaks (e.g. Kernel modules, init.d folder, etc)
- You have set custom CPU settings (e.g. custom frequencies with apps like No-Frills CPU Control, Set-CPU, Antutu, etc...)
- You have undervolted too low
- You have overclocked too high
- You have applied higher "Core OC" value in Trickster Mod App
- You are running any other kernel tweaks which are regarding to the CPU and/or performance (e.g. Kernel modules by Whirleyes eventually set by init.d, etc..)
- After setting some settings (e.g. in Trickster Mod) your device doesn't boot anymore
- adb doesn't work / shows only "device offline"
- You are facing hard lagging
If any point here matches your setting, please revert from it:
- Remove any CPU init.d script from /System/etc/init.d
- Uninstall any CPU controling app (e.g. Set-CPU, No-Frills, etc..)
- Remove all extra kernel modules from system/lib/modules (e.g. cpu_control.ko, cpufreq_smartass2.ko, etc..)
- Unset any custom settings from any other kernel / CPU - tweaking app which is NOT Trickster Mod
- Maybe your governor causes issues. Hotplug is know for bugs at the moment...I'm going to fix it..
- NEVER set your CPU Settings (e.g. in Trickster Mod App) on boot!!!! - before you aren't sure that your settings are safe!!!
- You may flash the kernel again after reverting related settings
- to make adb work / show device online, download latest SDK platform-tools and confirm access on device (4.2 security feature of Android)
- Don't use any task killers, memory killers, seeder apps! They may conflict with the kernel/Rom settings.
If none of these suggestions work for you your rom may be incompatible. Please report it here that I can add the rom to the list of imcompatible roms
If you have any issue, please read this:
First check:
- is it really a kernel issue?
- did I see this bug with the roms original kernel?
- what are the people in the rom thread saying?
- what are the people in the kernel thread saying?
- can I find this issue on a bug list?
- how about my settings? Is it my fault it crashed?
- can I find something useful in the kernel FAQ?
- Is it maybe a well known issue and can be solved
withing seconds? Just like wifical.sh?
- Where to repeat that issue? Rom or kernel?
I know it's sometimes difficult to track the issues, and we can't know for sure if it's caused by the rom or by the kernel, but if you try at least to get some information you might find an answer sometimes. If you are able to understand logs, you may report whatever you find.
All this helps to keep the threads more clear. Thank you.

Hey guys, welocme to JBX-Kernel for Targa! This is the first initial release and needs to be tested! Please give me some feedback if it boots and how it works for you. It comes with built-in OTA Updater and many extra stuff. Just check it out.
Keep in mind that this release will only work on 4.4 builds! Currently I don't have the time for others. Also you should use a newer build with Full HD Cam support! When using this kernel with older 4.4 builds your camera won't work.
Oh cool, i happy Someone help you with targa kernel ?

Nope.. But it doesn't matter. Currently I have a problem with paying my server, and as long as I am able to build I wanted to release the Targa Kernel. The only difference seems to be in the CMD-line (Targa doesn't have a utags partition), so I just had to switch this line and build it with CM11 Targa sources to get the right ramdisk and modules. The whole source is the same like RAZR kernel.
I test it, and dont see weighty differences with RAZR kernel, have same bugs, display backlights don't turn on sometimes. I think you can talk with Hush about it, he can help.

You mean Hashcode? I am in static contact with him. But thx
What do you mean with "backlight doesn't turn on sometimes" ? I don't see this problem on RAZR... But sometimes you need to be a little patient when you want to wake it up. That's because of things like "DEEP IDLE" and others which keep the device in "deeper" sleep mode. It can take 1 or 2 seconds until you will see the lights - but it will turn on for sure. Maybe you're talking about something else? What bugs else exactly?

Yep, i mean Hashcode.
It will happened if use proximity sensor when calling, and sometimes when wake up phone. Backlight don't turn on generally, help only reboot. And it don't happened if change frequency to 300-1xxx. I think if you change minimal frequency to 300mhz it gone.

Well that's not an issue, but a well known phenomen. Some devices cannot handle 100 MHz (depends on silicon, each one is different). The min frequency is 300 by default, and the battery friend min frequency is 200 by default. Just check your settings in trickster mod.

Not yet. I need more informations from other users. Any feedback here????
Just try the today's OTA (soon). I forgot to update device tree sources in yesterday's builds.
Because I had a weird drain myself on yesterday's RAZR kernel (not very much, but noticable)
EDIT: I got a workaround for the RADIO issue - if it's actually an issue Wait for the OTA.
I was only able to get radio working on your 1-08 build of the kernel for rzr. Ever since then I haven't been able to get it to come up.
Edit: I went ahead and installed your 1-21 update and its better. It eventually connects to LTE but only holds it for 30 secs and then drops with no radio. Thanks for the help in advance.

Please download the latest build from same links again (any mirror, I overwrote it). It should have fixed radio now. But you have to replace your build.prop with that one from your rom or open it and remove all additions made by JBX. The easiest way is to flash the rom again, then flash jbx.
I went ahead and redownloaded and reinstalled and I'm still getting the same thing. Attached is my "phone info" screen. And under "select preferred network" my only option is unknown

So, have you reset your build.prop before as I said above?
Btw: just open it in a text editor (I.e. With root Explorer), scroll down until you see "dtrail - build.prop additions". Delete everything below that line. Now reboot and flash jbx (after downloaded again).

I have the latest JB radio (CDMA_N_05.22.00R LTEDC_U_09.1D.00). My radio works fine using the stock CM11 kernel. I really wanna try out dtrails' work.
Update : Aug 8th 2017
These settings should benefit any helio X10 device maybe even other mediatek octa core devices.
The idea behind these settings is to keep the CPU in the lower frequency states and prevent unnecessary power drain when performing simple tasks.
to apply these settings I used Kernel Aduitor.
First Up Interactive Governor Settings
Code:
[SIZE="3"]Above hispeed delay - 20000 1326000:30000 1469000:40000 1781000:10000
Bootpulse duration - 0
hispeed freq - 1183000
boost - 0
go hispeed load - 70
io is busy - 0
min sample time - 20000
target loads - 60 1183000:80 1326000:90 1469000:97 1625000:99
timer rate - 25000
timer slack - 35000[/SIZE]
Limit you CPU to 1781MHz To save some battery all 1.9GHz does is produce heat and the performance isn't worth it.
Also you must disable touch-boost by editing the build prop line; ro.mtk_perfservice_support=1 to ro.mtk_perfservice_support=0
This will save a lot of battery life as the CPU won't jump to high frequencies when you touch the screen.
Also in Virtual Memory settings set the folowing
dirty ratio - 90
dirty background ratio - 80
dirty expire centisecs - 1000
dirty writeback centisecs - 2000
swappiness - 40
vfs cache pressure - 10
Z-RAM disksize - 300MB
Next up....... RAM management so the HTC X9 RAM management is good but it can be made better by going into the low memory killer tab in Kernel Auditor and tapping on the light option.
and that is it. we can't do much without a custom Kernel......... Also you can increase entropy by changing it's read value to 1664 and write value to 2048. I don't know if this is needed on marshmallow but I did it anyway.
Even more battery Savings
You will need Tasker for the following.............
Note: This Will limit your CPU to 5 cores and reduce unecessary CPU Scaling also will disable some bug checks
Make a new 'device boot' profile and add the following as tasks
1. Wait 30s
2.Run Shell:
Code:
[SIZE="3"]

jajk - Learned a lot from his Skinny Custom Boot thread.
I haven't noticed any freezing on my device. Everything runs smoothly all the time.
I will test your settings if it starts annoying me.
I guess the x9 isn't the most popular phone for rooters.

thx.methods u said work on my htc x9.but like the 'Even more battery Savings' i not done yet
Htc one x9
Hello, am new here. I came on here cos I need help with my HTC One X9. You have to forgive me if I ask dumb questions cos like I said earlier, am new to everything here. So please be patient with me.
While in use, my fone drops from say 90% to zero and then shuts down. After a while when I turn it on, battery returns to 90%. At other times, while in use it shuts down even when charging....in this state it reboots several times and gets very hot.
Please what can I do? Thank you.

(PnP&Thermals tweak)battery saving and better performance for m8 100% working[ 11/8]
I'm not the dev
1st of all thanks to @ivicask for making this awesome tweak
Original thread :> http://forum.xda-developers.com/htc-10/development/pnpthermals-tweak-customized-profiles-t3411860
This is the better battery saving and performance tweaks ever I face best battery life after flashing this tweaks
This tweak originally for m10 and it's available on venum hub and m10 development thread i was tested this and it's work perfectly on m8 without any issues so I decided to bring to m8 users
bugs
Sorry no bugs

[*]
8.11.2016
v19:Fixed CPU dosnt drop to lowest speed for some users/kernels
- Merged v18 balanced changes into performance profile
working on cm 14.1 and old or gpe base rom and aosp,lyrs
22.09.2016
v18Balanced changes only)
- Adjusted CPU scheduler load distributions and frequencies in order to fix some stutters,
but also to save power while phone is idle with screen ON (drops to lower frequencies faster)
- Fixed weird HTC bug where task migration gets stuck in loop and cause phone to heat up for no reason
- (thermal file)Make it a bit cooler on higher loads
- Minor fine tuning here and there..
29.08.2016
v17: Prevent cores going offline if running Android auto (fixes lag on screen off)
[*]- (Balanced)Tweaked 15+ various governor and boost settings for even more power savings
[*]- (Balanced)Added more appps for CPU limiting profiles
[*]- Allow 4 threads for oat proces if PlayStore in focus(faster app install)
[*]23.08.2016
[*]v16:Merged latest HTCs changes realted to PokemonGo thermals
[*]- Removed 50 -> 60 fps boost on touch on performance profile(60fps locked now)
[*]- Forced 60 fps for YouTube and Google videos on balanced profile
[*]- Tweaked thermal file on balanced profile for better performance
[*]07.08.2016
[*]v15:Balanced and Performance profile update
[*]- Fine tuned values
[*]- Big cores go offline during screen off for Performance profile
[*]- Tweaked low memory killer values on both profiles,
[*] prevents often app reloading, which is waste of time and battery.
[*]04.08.2016
[*]v14:Balanced and Performance profile update
[*]- Implemented dynamic swappiness
[*]- Default swappiness reduced from 60 to 30 (less writes to nand)
[*]- During app launch or touching screen event swappiness is reduced to 0
[*]- During screen off swappiness is set to default 60 so it can do its job when we are not using phone
[*]- Increased dirty_ratio to reduce even more writing to nand
[*]- Overall goal is to reduce I/O on NAND while using phone and in that way improve performance,
[*] but also improve battery by better utilizing the 4gb RAM that this device has.
[*]- Added more apps for CPU limiting profiles(balanced only)
[*]v13:
[*]-Merged with changes from 1.9x base
[*](Mostly fine tuning battery saving for various video chat programs)
[*]v12:Balanced profile changes
[*]- Added more commonly used apps for lower power CPU profiles
[*]- More fine tuning
[*]v11:
[*]- Fine tuned balanced profile to prefer a bit more battery life
[*]- Cleaned up aroma installer (wont create unnecessary Venom folders for non-Venom users)
[*]v10:Balanced profile rebuild
[*]- Merged and fine tuned/adjusted thermal configuration from performance profile
[*]- Should improve responsiveness and fix stuttering on some apps that happend before
[*]- changed around 100+ lines of code, lazy to write full changelog
[*]v9:TEST balanced profile update
[*]- Big cores will now go fully offline during screen off and while in Extreme powersaver
[*]- Lowered screen refresh rate while in Extreme powersaver(even more saving)
[*]- Max GPU speed limited to 214MHZ while in Extreme powersaver
[*]- Max GPU speed limited to 510MHZ while in powersaver

[*]v8: complete rebuild of performance profile
[*] - Added extra 560mhz frequency step between 630 and 510 for GPU throttling
[*] - Added 5 additional throttling steps for each CPU cluster per temperature
[*] - Prevent big cores dropping to 1.3ghz too soon which drops FPS in games.
[*] - Prevent killing one big CPU core too soon, instead 2 will run at half migration performance.
[*] - Everything fine tuned and balanced, 10+ FPS boost in most games compared to stock
[*]v7
[*]- 1.8x base compatibility update
[*]v6
[*]-Removed battery saving profile as balanced does such good job, both smoothness and performance!
[*]v5
[*]-Many changes to balanced profile
[*]-Lowered app launch Max CPU speed locking to more reasonable levels(Still ramps up to max if load demands)
[*]-Reduced input boost duration a bit
[*]-Governor will now drop CPU to lower speeds faster
[*]-Added more apps to lower CPU speed profiles.
[*]v4
[*]-Aroma installer fixes
[*]-BatterySaving profile fine tuning
[*] Quote:
[*]This addon is designed to save some extra battery, and reduce heat.Magic is done in 2 files:
[*]1:Thermal-engine is tweaked in order to provide much better sustained performance and cooler phone, without big impact on performance.
[*]2np file is another key component, its HTCs CPU/GPU/EMMC/MODEM and many more control engine.Here many tweaks where done, but gonna quickly list some of the important ones:
[*]-Per app control, automatically suspends 2 BIG cores, and runs on 2 low power ones, it also limits the GPU speed to lowest.This will do only for some most commonly used apps, like Sense Prism, Nova launcher, Apex, other HTC apps, various chat programs(hangouts, facebook, messanger, whatsap etc), YouTube and some more.. as those apps dont require a lot power.
[*]-Screen off is set to 2 low power cores for nice standby times
[*]-Power saver is tweaked to actually save some power and not just lower screen brightness
[*]-Extreme powersaver is also tweaked down to save even more power
[*]-Input boost frequencies are also lowered (CPU ramps up moment you touch screen)
[*]-And alot of other minor tweakups..
[*]Also its recommended not to change anything CPU/GPU related in any other apps, like EX and just let this files do the job for you.
[*]If for some reason you dont like this mod or have any problems with it, installer includes revert to stock option
[*]
[*]Compatibility
[*]All 1,8x and 1.9x based roms and kernels(even stock).
[*]Not compatible with 1.5 or below bases (will cause random crashes), use Version v8 for older 1.5x and 1.2x bases
.work
Only on sense based rom like srom ,viper,sky dragon and other cm,aosp,gpe lyrs

Woot!This cant possible work good, M8 pnp is totally different and works with on-demand governor with cores hotpluging while htc 10 works with interactive, not to mention all the settings i did in PnP are tuned to snapdragon 820 cores and memory management of that device (4gb).
Alo thermal file may not work properly and cause device to overheat(may)
.
You should verify what governor is currently active, i think its just broken and reverting to some default kernel or system settings.
BTW, M8 CPU management is already amazing so i never did special pnp mod for it.

Well the Developer Knows Best, because he did it and he know what exactly he did, so can be placebo or even if its work some parts will some parts not like u know HTC 10 have different Hardware specs.
My Other question related to the HTC BUG is do anybdy found a Solution Tweak for the well know HTC BUG mostly all M8 M9 Devices after the MM update suck on the Battery the phone die at 20% 20+ something % and losing all settings when start from scratch its frustrating bug Ive tryed 100 Different kind of Calibration nothing help me out to fix this problem. sometimes Die at 25% battery Sometimes die at 10% battery without a warning!

Well i was thinking the same way untill i realize this heppand imideately after flashing MM and after this found out hundred of people with M8 as well M9 have absolutely the same issue stright after the MM update so this cant be co incident also i did chek my battery with several tools its in good health.
thats why i think its a HTC Bug.

Did you replace battery I think u have to do if you believe trust me in my honest opinion it's battery problem my brother have same phone and he did same way like me so once u have to do . Before replacing battery I did all possible thing but nothing helped like celebration and more but finally get success on battery replacement

Only way you can try calibrate battery is by draining it fully until you can't even turn it on back via power button, than plug charger and leave it turned off while it charges to full. If it doesn't help its bad battery, as my sisters M8 works just fine with latest android and shuts down on around 1%..
GPE
Any chance of this coming to GPE roms?

R u going to do some changes for m8 hope ?
As expected, flashing HTC10 PNP breaks PNP and almost none of my settings are active, it still runs ondemand while entire htc10 pnp is coded to work with interactive...
I dont feel like taking sisters M8 to work on this, its not even rooted... or bootloader unlocked..
And as i said, i find M8 governor already perfectly fine coded HTC side..
confirmed working great on jw 5.4.0 A9 port.. battery lasted longer
thanks a lot..waiting for Blur Os new stable port
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.
CHANGELOGS
L-Speed Profile (download the app on PlayStore):
011118 lspeed profile
- first release
031118 lspeed profile
- 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.
SmartPack Manger Profile (download the kernel and the app here):
301018
- first release.
011118 smartpack profile:
- A few Interactive governor tweaks;
- Removed Virtual Memory and LMK tweaks, let it on default or use L-Speed to optimize, as it does a much better job then me.
031118 smartpack profile:
- 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
081118 smartpack profile:
- target_load (no changes up to 1497600) ...1728000:89 1958400:91 2265600:95 -> ...1728000:88 1958400:90 2265600:95

- cleaned unused and already default values from profile
101118 smartpack profile:
- Turned Alucard off, accidentally activated it with Lazyplug also enabled, not good!
- Managed to go 1 point higher on freq 1497 MHz, the 2 hotplugs enabled were messing with me trying to test this change before, also 1 point lower on the idle freq 268 MHz for smoother scrolling while still staying at freq 268 while idle. And some more high load optimizations now that I only got 1 hotplug enabled as it should always be.
- target_loads from 268800:29 ... 1497600:86 1574400:5 1728000:88 1958400:90 2265600:95 to -> 268800:28 ... 1497600:87 1574400:5 1728000:89 1958400:91 2265600:94

- dirty_background_ratio 15 -> 10
221118 smartpack profile:
. Reverted new SmartPack Kernel v14r4 changes to Virtual Memory back to original default configurations, if you've have had reboots this should fix it, please report back here and/or the kernel's thread;
. More changes to Interactive governor aiming to optimize high load scenarios according to the profile philosophy:
. above_hispeed_delay 20000 1190400:60000 1728000:74000 1958400:82000 2265600:120000 -> 20000 1190400:60000 1728000:74000 1958400:80000 2265600:105000;
. Enabled fast charge configurations, set at 1200 mhA as I found it's a good charging speed without heating the phone too much on my hot city, nothing you can't change at your will.
241218 smartpack profile:
. Restored missing min_sample_time tunable since 081018 profile
. dirty_ratio 30 -> 25
. General cleanup
. Tested on Pie
@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

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?

I don't use SD card so what do I do?

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.
edit:
101118 smartpack profile:
- Turned Alucard off, accidentally activated it with Lazyplug also enabled, not good!
- Managed to go 1 point higher on freq 1497 MHz, the 2 hotplugs enabled were messing with me trying to test this change before, also 1 point lower on the idle freq 268 MHz for smoother scrolling while still staying at freq 268 while idle. And some more high load optimizations now that I only got 1 hotplug enabled as it should always be.
- target_loads from 268800:29 ... 1497600:86 1574400:5 1728000:88 1958400:90 2265600:95 to -> 268800:28 ... 1497600:87 1574400:5 1728000:89 1958400:91 2265600:94

- dirty_background_ratio 15 -> 10
I will give this a try. Hope it works well...
Yeah.
You know, try it and report back. I don't see any reports, so I assume is working well for people.
Any reports are welcome.
