motley kernel for the Nexus 7 and Jellybean
Disclaimer: You know the gig...I am not responsible for damaging your device or voiding your warranty. Play at your own risk!
ROM devs/cooks: If you want to use this kernel in your ROM, I am fine with that, but please include a "thanks" and a link back to this thread. Thanks!
Requirements (please read carefully and visit the other dev threads as necessary)
You must be unlocked and rooted.
You must have custom recovery installed (CWM or TWRP) to install the kernel.
Busybox is required for init.d support.
Do a backup using custom recovery (CWM or TWR) so you can restore your boot.img and ROM if necessary!
Have your ROM zip in /sdcard so you can restore your ROM if necessary.
System Tuner is recommended for tuning the CPU, especially for voltage control.
Main Features
GPL compliant - source is kept up to date at github.com and released at the time the kernel is released to the public for all builds. Ask other devs to do the same!
Asus\Nvidia\Google Linux 3.1.10 base. All stock features are supported (camera, OTG, NFC etc.)
OC to 1.6GHz (optional)
Voltage control - be careful to not save the setting on boot until you are 100% sure!
GPU OC from 416 to 520MHz (default is 446, adjust as you wish up to 520MHz)
Dynamic EDP - allows EDP to remain enabled (safer), but with an added simple temperature throttle switch (based on Asus Prime)
Compiler optimizations (-O2) - using Linaro 4.7 ARM toolchain
I/O schedulers - row (default), SIO, V(R), CFQ, NOOP, and deadline
TCP Congestion Control - default cubic + several different algos to choose from.
ZRAM - must be enabled by a script
Governors - Interactive (default), Performance, OnDemand, PowerSave, Conservative
initramfs - insecure (your ROM must have busybox)
CIFS/UTF8, NFS, NTFS r/w, TUN - built-in, no need for any kernel modules
fsync sysfs enable/disable switch (defaults to fsync enabled)
kexec with hardboot (for supporting Linux/MultiROM)
Many other misc patches and tweaks (see github link below)
Install:
Check the requirements above!
Flash the zip using custom recovery (no need to wipe anything)
See post 2 for performance tweaks and more info

kexec\MultiROM support
Download from here since I posted in the MultiROM thread
build #244 for Jellybean 4.2 - WiFi and 3G - Recommended for WiFi and 3G on 4.2.x
446 GPU build (stock + 30MHz). Let's see if this fixes touchscreen issues for those having them. My theory is that after the GPU heats up, this starts to affect touchscreen behavior on some devices. This is likely what happened to me on build 234 when I was testing. The GPU definitely gets hot on this device even with normal usage at 484+. At 446 this doesn't happen. IMHO, we are reducing the life of the device by overheating the GPU repeatedly. My Antutu scores actually tested higher after I flashed the 446 build.
Supports Android Jellybean 4.2.x
Reverted some commits from 233
Removed KSM from config, no ROM is using this AFAIK
Panel clock reduced to match Nvida cardhu sources (74180000). Having the panel clock cranked up fakes out scores on some benchmark tests, but adds no real value.

Previous builds and release notes
build #234 for Jellybean 4.2 - First properly working 3G build
Supports Android Jellybean 4.2.x
Only change - added CONFIG_USB_NET_RAW_IP=y to hopefully address any issues with 3G (reported working by DiamondBack)
View attachment motley_nexus7_anykernel_build_234_484GPU.zip
build #233 for Jellybean 4.2 - if you don't have issues with GPU OC @484, this build may work well for you.
Supports Android Jellybean 4.2.x
Updated to latest Linaro toolchain 2012.10.22 and tweaked some compiler options.
Should support 3G as I have merged the Google patches, but I have not tested this.
Removed WiFi PM_FAST toggle as I see no need for this (PM_MAX for better battery is already the default in stock)
Stopped logging temp warnings until lit gets to 65C near the EDP throttle limit.
Quad-core tweaks - referenced showp1984's bricked grouper kernel source
See github for other minor details.

build #232 - Recommended for WiFi on 4.1.2
Added support for Android Jellybean 4.1.2
Updated to latest Linaro toolchain 2012.10.22.
View attachment motley_nexus7_anykernel_build_232_484GPU.zip (GPU OC 484MHz)
stable v1.1.1 - builds #218-220 - Recommended for WiFi on 4.1.0 or 4.1.1
Supports Android Jellybean 4.1.1 or 4.1.0
DVFS tweaks and drop top cpu frequency to 1600, not much is lost and it should now be stable for everyone I hope. We pushed the envelope to 1.7 and 1.624 and now we are back to real world sensible decisions. My Nenamark2 520 GPU scores actually went up.
Dynamic EDP temp adjusted from 67 to 68C to catch temp notifier quicker when cooling back down.
Other miscellaneous patches
Just in case, please note and then unset your saved voltage control settings before using the new version. You may need to clear your System Tuner App data to see the correct frequencies. Remember that the DVFS table and the scaling frequencies are different in some cases (see the second post for details)

alpha v1.1.0 - builds #213-215
Added fsync sysfs enable/disable switch (thanks Ezekeel). fsync is still enabled by default. For more info and how to disable, see post 2.
Experimental: now forging speedo id 4 and process id 2 so that EDP limits are slightly raised and it narrows everyone down to a common DVFS record for everyone. Raised Dynanic EDP governor to 67C (from 60C) to give a little more room before edp is allowed to enable.
Minor cpu voltage table tweaks aiming for slightly better battery for those that don't undervolt.
Lowered the cold offsets from 50 to 25 for the top 4 cpu voltage slots. This will give folks a little more breathing room when undervolting and may help cold performance a bit if your voltages are lowered close to their lower limit.
Deadline i/o scheduler (morfic's secret 1:1 sauce that I remember back from my Iconia A500 days!). SIO is still the default, but we can try it out and see what we think.
OnDemand really wasn't usable in it's stock state since it was so laggy, so I have made some tweaks to the tuneables and it seems to be better now for those that want to give it a spin. Interactive is still the default governor.
cpu transtition latency lowered - fairly certain that it only affects OnDemand governor and not Interactive (reference morfic and http://permalink.gmane.org/gmane.linux.ports.tegra/1649)
Reverted most of the adjustments to the tegra 3 algorirthim for bringing cpus online and offline. I think it livened it up, but at the expense of battery.
Added kernel config option BCMDHD_WIFI_PM (thanks Ezekeel). See post 2 on how to enable it (not recommended unless you have music steaming issues when the screen is off). Not yet tested.

stable v1.0.12 - builds #175-177
Changed highest frequency back to 1.624GHz and core voltage back to 1200mV. After experimenting with higher core voltages and 1.7GHz probing our limitations, it just doesn't seem right on this tablet. Why fry the butter?
CPU voltage is capped at 1237, so don't set it higher than that if tuning.
Refresh rate now adjusted with GPU OC clock at compile time. Higher FPS should be realized at 484 and 520 for most (thanks to clemsyn for sharing his research and findings)
Adjustments to the tegra 3 algorirthim for bring cpus online and offline, especially for the OC frequencies.
Fixed GPU clock compile time switch. Removed 500MHz choice.
Set cpu frequency policy to 1.3GHz on startup. This should help with heat build-up on startup and users where the highest OC clock rate is not desired.
Lowest brightness setting set back to stock since several users were requesting it (18 back to 13).
Minor adjustment to the interactive governor to make it slightly more responsive when demands increase.
PowerHAL change so it doesn't mess with a couple other interactive governor tunables on init.
All frequencies throughout the power range should be used in a more balanced manner.
Just in case, please note and then unset your saved voltage control settings before using the new version. You may need to clear your System Tuner App data to see the correct frequencies. Remember that the DVFS table and the scaling frequencies are different in some cases (see the second post for details)

View attachment motley_anykernel_nexus7_1.0.12_GPU520_build_175.zip (GPU OC 520MHz)
alpha v1.0.11 - builds #126-128
Changed highest frequency from 1.624 to 1.7GHz
Increased core voltage for the highest frequency to 1250mV. This should bring some increased stability at the highest two overclock frequencies (thanks to clemsyn and Pinoyto for their help)
Tweaked DVFS table for the GPU. It should now scale a bit better and still bring the same performance and the top end.
Lowest brightness setting increased from 13 to 18 (thanks to clemsyn). Lets give this a try and we can increase it further if need be. The brightness levels can be tweaked on the ROM side as well in the N7 device tree, at least when you build from scratch, so we don't want to be too limiting here.
PowerHAL fix now included /vendor/lib/how/power.grouper.so (thanks to imoseyon). See this post to see the code I changed.
(Removed download links since many were reporting random reboots. I think v1.0.12 is better anyhow)
stable v1.0.10 - build #110/111
CPU frequecies back to 1400, 1500, 1600, and 1624 (leaving the new highest setting)
DVFS table tweaks
Frequency table fix fix for 1624 (thanks to Clemsyn for bringing to my attention!)
Only stock and 484MHz GPU OC version - code switch is still there for those that want to compile and experiment. Moving beyond 484 doesn't show any benefit. My best Nenamark2 score 62.7 was achieved on 484MHz.
Just in case, please note and then unset your saved voltage control settings before using the new version. You may need to clear your System Tuner App data to see the correct frequencies. Remember that the DVFS table and the scaling frequencies are different in some cases (see the second post for details)
experimental v1.0.9 - builds #102-105
CPU OC to 1.624GHz - higher end CPU frequencies are now at 1408, 1504, 1600, and 1624 (old 1400, 1500, 1600, N/A)
DVFS table tweaks - Just in case, please note and then unset your saved voltage control settings before using the new version.
GPU versions stock, 484, 500 and 520MHz builds for testing
Added a GPU OC kernel config choice switch to allow compile time selection of GPU speed (446, 484, 500, or 520MHz).
NTFS r/w enabled
PegasusQ governor no longer built in, but code remains if we want to look further into when time allows.
Reduce some temp reporting kernel log spam until the temp gets a little higher
stable v1.0.8 - build #77/78
Added PegasusQ governor - experimental only, not enabled by default (thanks Samsung SGSIII source and gokhanmoral for tweaks)
Revert "HACK: block fbearlysuspend to not break androids crt-off animation"
Added LulzActive governor, but not built-in due to issues.
stable v1.0.7 - build #70/71
Voltage Control tweak - let's ignore the highest freq slot for show and
save since it shows 1.6GHz twice in the voltage table in System Tuner.
We are are only allowing 1200mV for 1.6, so the top slot is not
currently used. See my notes in post 2 about voltage control.
cpu-tegra: let's skip the temporary downclock and kernel log spam if the
custom Dynamic EDP throttle is not currently enabled.
ARM/VFP compiler optimization
compilation: fix annoying and serious warnings (thanks faux123!)
video: tegra: host: Fix error case memory leaks
When a submit fails, the related nvhost_job is not freed. Add an
explicit free. Also, 3D is mapping the save buffer, but it is not
unmapped (Nvidia)
mm: Ensure pte and pmd stores ordering (Nvidia)
Get rid of some more kernel log spam.
HACK: block fbearlysuspend to not break androids crt-off animation
(thanks codeworx, drewis (repo) and aaronpoweruser for pointing it out). This is untested (by me), but this may help with ROMs that
have this functionality (AOKP etc.)
cpu-tegra3: modified the hot-plug governor down_delay to be 1s
instead of 2s
stable v1.0.6 - build #47/48
GPU clock increased to 484MHz - Nenamark2 scores of 61+
More compiler optimizations (-fmodulo-sched, -fmodulo-sched-allow-regmoves, -funswitch-loops, -fpredictive-commoning, -fgcse-after-reload, -ftree-vectorize, -floop-interchange, -floop-strip-mine, -floop-block, -mfpu=neon )
Now using Koush's AnyKernel delivery method. Uses your existing ramdisk so you can easily use with any ROM.
stable v1.0.5 - build #39
Honor your max frequency fix - no more spikes
alpha v1.0.4 - build #38
Fixes units that can't OC (process_id = 3)
Linaro 4.7.1 toolchain -O2 (2012-06-25)
Increased panel clock rate - increases fps without further GPU clock Nenamark2 scores 59.6 best score so far for Nexus 7
ramdisk added back in boot 1.3GHz, but device still spikes to max allowed CPU freq sometimes (see update below, will be fixed in 1.0.5)
Minor clock and voltage adjustments - should run a bit cooler and use less battery.
Added GPU OC compile switch in case we want a non-OC GPU build.
Added some VPN/networking capabilities for those that need it (L2TP, IP_GRE_DEMUX,INET_AH, INET_XFRM_MODE_BEET)
Some unnecessary debugging options turned off. Should save kernel RAM usage.
Some say it made wifi signal stronger again for them, but I never had any issues. Might be the toolchain and its effect on the broadcom driver. Reports that it is better are fine with me!
alpha v1.0.3 - build #17
UV support, minor voltage adjustments
V(R) i/o scheduler added
ramdisk removed custom init.rc line...hope this will fix the stock units that weren't booting!
alpha v1.0.2 - build #6
Mild GPU OC from 416 to 446MHz - baby steps...its been rock solid so far. NenaMark 2 scores are up from 55 to 57.2fps. A future release may have two versions, one with GPU OC and one without.
Upgraded toolchain to GCC v4.6.3 optimized google version by ezterry, see http://forum.xda-developers.com/showthread.php?t=1686310)
alpha v1.0.1 - build #4
Limit frequency to 1.3GHz on boot. It can then be OC'ed from there. This should make it safer for those that can't OC or don't want to.
Changes to allow OC for Process ID's 0 and 1. Theoretically, these should be earlier release versions like IO and earlier.
alpha v1.0.0 - build #1
This initial alpha release is working well on a Nexus 7 16GB (Speedo ID 7/Process ID 2) on JB 4.1.1. There are no open issues that I know about. Looking for some advanced users and testers to give some feedback, and then we can hopefully make it even better!

More info
last_kmsg
Please provide the dmesg output or last_kmsg if you experience any issues (random reboot or crashes) that you think are attributed to the kernel. I ask that you please test with the default/stock kernel first for your rom before you blame the issues on this kernel. Wait for the tab to reboot, or if it doesn't wait long enough so you can capture a good log. If you place this on your /sdcard, it will be easy to capture. Boot into recovery, flash this zip, and then flash a known kernel that works. Then reboot, and go grab the last_kmsg in /sdcard.

Voltage Control
What is voltage control?
It is simply allowing for the cpu voltage to be changed on the fly for each frequency step. CPU voltage is typically lowered (undervolting) for certain frequency steps to conserve power. For an overclocked device, some devices need more juice to be stable than others. Voltage control allows others not to pay this penalty and they can lower the voltage as they see fit for their device and usage needs.
Is undervolting safe?
If the lowered voltage values you enter are stable for the tablet, then absolutely it is safe.
What are the benefits?
Better battery life and less heat
Additional Info on voltage control
Only System Tuner is displaying the DVFS table frequency labels correctly and I recommend that you use this if you want to play with voltage control. SetCPU is showing the scaling frequencies when it displays them in the UI, some of which are for the LP core. This is not correct and is misleading, so it is best not to use it for this kernel.
Since the tools available only allow for tweaking one DVFS table (the high powered G cores), voltage control is not currently possible for the LP core. It is not needed anyhow IMO and setting it too low could result in SOD. There is more battery saving to be had with the G cores anyhow if you are into this sort of tweaking.
The frequencies shown may have two values for one frequency. This is how it came with the factory kernel as well and I have only tweaked the top end of the DVFS table. It may seem weird, but this gives us direct access to the DVFS table. I would recommend keeping it as a staircase, just like Nvidia has it even though some frequencies are listed twice.
The freqs shown in the System Tuner display will match the DVFS table for the cpu_process_id for your tablet (seen in the kernel log at startup). All tablets won't display the same frequencies. There are at least two maybe three or four variants we have found so far for the Nexus 7 with Tegra 3 SoC #7.
Also, some may not know, but the tegra3 kernel also has automatic UV using a "cold" zone in where 50mV undervolting is done automatically when the cpu is cool. Take this into consideration when playing around.
GPU OC
Valid max GPU frequency is 416 - 520 MHz. If you try higher or lower clock speeds, it will fail and remain unchanged.
Examples:
Code:
echo 484 > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
Code:
echo 520 > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
Performance Tweaks
These are a couple of tweaks that many are using for faster benchmarks and better battery performance. Google it and decide for yourself if you like the risk or not. I recommend that you do a full backup in recovery and regularly backup your /data partion or cloud sync if you enable these options. Will many run them daily as I now do, there is some additional risk. These can be added to scripts and automated via init.d or other apps/tools that support them.
To disable fsync for better battery and better disk i/o performance:
Code:
echo 0 > /sys/class/misc/fsynccontrol/fsync_enabled
To enable fsync for better data integrity (default)
Code:
echo 1 > /sys/class/misc/fsynccontrol/fsync_enabled
Faster disk i/o - remount /data partition with noauto_da_alloc option (google it, better battery, less data integrity)
Code:
mount -o remount,noauto_da_alloc /data /data
TCP Congestion Control Algorithms
Only one can be set at a time, so only add one of the lines to your script. Here are some examples:
Code:
echo "reno" > /proc/sys/net/ipv4/tcp_congestion_control
echo "veno" > /proc/sys/net/ipv4/tcp_congestion_control
echo "vegas" > /proc/sys/net/ipv4/tcp_congestion_control
echo "westwood" > /proc/sys/net/ipv4/tcp_congestion_control
zRAM
What is zRAM?
This is a mainline kernel feature for Compressed RAM block device support (CONFIG_ZRAM)
http://en.wikipedia.org/wiki/ZRam
Like many of the other tweaks done in the Android world, ZRAM is another one of them that is controversial, probably because people only think in terms of immediate performance they can measure easily with benchmarks etc. *Here is my take...think I will add this to the Q&A section as well.
But, will it make my device faster? Will I score higher on benchmarks?
It depends, but for normal usage, the answer is no. zRAM is most useful for those that are configuring Android to be a true multitasking workhorse. For example, if I enable zRAM, open an bunch of apps at one time, and actually start to work towards depleting the memory of the system. *For example, say I open system tuner, a browser with several tabs, a word processing app, a game, and perhaps a picture viewing app or a movie. If I don't formally close out of each one by hitting back and just begin switching between apps and the home screen, you will see zRAM start showing benefits.*
If you tweak the Android memory and swappiness settings, this can also be useful in this type of environment.
How do I know it is initialized and working?
You can type "free" from an command line and see the swap space.
Also, you can look at the disksize to see if it is initialized
cat /sys/block/zram0/disksize
To see how much it is being used in your environment, you can look at the output from:
cat /sys/block/zram0/num_writes
cat /sys/block/zram0/num_reads
So, unless you have a heavy workload as stated above, then it won't be of a lot of use for normal Android users.
How do I enable zram?
It must be enabled by a script. Some ROMs may support activating it. If you need to do it yourself you have two choices.
1) Save this to a file and run the script from terminal, Script Manager or System Tuner.
2) Or better yet, save this to a file called 90zram (or whatever you prefer) in /system/etc/init.d and automate it (The ROM's ramdisk needs to supports init.d)
Code:
#!/system/bin/sh
# auto zram activation init script with busybox search
# by show-p1984
echo "[90ZRAM]: Firing up /system/etc/init.d/90zram";
if [ ! -e /sys/block/zram0/disksize ] ; then
echo "[90ZRAM]: ERROR unable to find /sys/block/zram0/disksize";
echo "[90ZRAM]: Is this a ZRAM kernel?";
echo "[90ZRAM]: ZRAM NOT ACTIVATED. (404)";
else
#find busybox in /system
bblocation=$(find /system/ -name 'busybox')
if [ -n "$bblocation" ] && [ -e "$bblocation" ] ; then
echo "[90ZRAM]: busybox found in:" $bblocation;
echo "[90ZRAM]: Setting ZRAM disksize.";
echo $((100*1024*1024)) > /sys/block/zram0/disksize
echo "[90ZRAM]: Starting ZRAM...";
bblocation=${bblocation%/*}
cd $bblocation
./busybox mkswap /dev/block/zram0
./busybox swapon /dev/block/zram0
echo "[90ZRAM]: ZRAM activated.";
else
echo "[90ZRAM]: ERROR! busybox not found!";
echo "[90ZRAM]: Is busybox installed? Symlinks set?";
echo "[90ZRAM]: ZRAM NOT ACTIVATED. (404)";

Flashed with CWR and it doesn't boot past the Google screen Is there something special I need to do?
*Edit*
I am on the new 4.1.1 "D" or whatever but right now I'm using the Atlantis "1.5" kernel and it works so I donno.
Thanks for another addition to the nexus 7 kernel community, love having different kernels to try.

Thx, please grab the dmesg output while booting or last_kmsg if you can. Working fine here, but this why I put it out as an alpha. Even if you boot off another kernel, if you can send a dmesg captured right after boot, that would help so I can see your SoC/Process ID numbers. There are two lines written just after boot with the info. On the Prime, we had different CPUs in some models, but it may just be a voltage issue. I have run Antutu and Quadrant several times without issues though. Not sure about the D update...I I have 4.1.1.
Edit: Version 1.0.1 released, please test again and leave feedback when you can. Please let me know when you received your tab. Is it an early IO version? If this doesn't do it, I most likely will need to increase voltages a bit. Hopefully I won't have to do this so we can keep battery life at it's best.
oh s^&*, you developing here also. oh yeah! glad to see you here buddy. so you have your nexus 7 already? now that i see you here also, i will be unlocking my nexus 7, once it arrives, sooner than i thought. welcome aboard...glad to see familiar faces around here
I had the same issue. Couldn't pass the boot screen after flashing. On 4.1.1 latest update as of July 15th

Thanks, I am dying to take a look at a log to see how I am so lucky to have it working! I've added LastKMSG.zip to the OP. If someone with a booting problem can do the following, I would really appreciate it:
1) Put LastKMSG.zip on your /sdcard along with the newest kernel zip
2) Flash the kernel zip
3) Wait for it to boot, give it a few seconds and then hold power down to reboot if it doesn't do it on its own.
4) Go back into recovery and flash LastKMSG.zip
5) Flash another booting kernel or your current rom to recover.
6) Boot and retrieve the file /sdcard/last_kmsg
7) Attach the log here or PM me with a dropbox link or whatever.
Thanks!
Just got some good news from a gentleman that didn't have enough posts to share with us here yet, so he PM'ed me and said that I can share the details of his experience.
First report was more of the same, sounded familiar, more bad news...
Flashed your kernel and couldn't boot pasted Google screen. Restarted in to boot and couldn't get into recovery. Was stock rooted on the latest 4.11. Went back to stock. Looking forward to trying again, now I'm on Modaco's latest. I'll let you know how it goes.
Next report was good using the latest version in the OP. Not sure, but this may help others.
Thanks! This kernel is fantastic! Makes this thing a real beast! Sorry I didn't give you the info you asked for! I got it Thursday from GameStop. The problems may have stemmed from the fact that I updated to 4.11 , rooted then side updated the newest little update and then ran a su zip to regain root (Paul o' Brian ROM) . I was also on his first cwm and then updated to his new one after I started from scratch. Loaded up his new ROM, rebooted then applied your 2nd kernel and this thing is hitting 15626 in CF benches!
Not sure what is going on, but I can't explain it. It may be my 2nd version of the kernel that fixes it, but I am not sure since I haven't seen a log yet. I suppose something may be jacked up with the early versions of recovery or roms, but the I was using the the same early versions when I tested just fine....maybe folks are losing recovery and don't realize it? I did the second step to keep recovery that is now automated in r2. If anyone has any ideas, let me know.
New version released
New version released...see OP. GPU OC to 446MHz (up from stock 416)

Just out of curiously, would you ever try 520mhz for the gpu, to try to get it to t30 speeds? Or maybe would you consider some kind of app interface like extweeks for the galaxy s2 & s3 to control the GPU clock speed and maybe voltages instead of different kernels. As I would personally love to get the GPU to about 460-500mhz Anyway when I get my n7 (hopefully in a day or two) I can't wait to try this out (I am spoilt by the much more powerful 440mhz mali-400mp in the s3, so I would love to try to narrow the power difference between the devices GPU wise)
Nice man! The new versions fixed everything boots great! Now if we can just figure out how to make the Overclock stick after you turn the screen on/off. I'm not sure how to tell if the GPU OC is sticking.

Sure, we may push the GPU OC version a bit, but I always like to walk before we run to see how things go. I would like to monitor heat output, battery usage etc. and then move forward in steps. I am very happy with it right now, but dynamic configuration would also be cool. Let me know what you think once you have it hand.

Awesome, glad to hear it! I don't think I see this issue with the OC sticking after you turn the screen off/on, but I will do more checking after work today.

Thanks a ton! Yea if you go into setcpu and make it 1.6 then turn the screen off then on (unlock) set CPU slider still shows 1.6 but if you read under that the smaller text says its actually set at.1.3 again. It seems to be a problem with the Atlantis kernel also something to do with hardcoded CPU freqs I think. Oh I wanted 5k soooo bad rofl got this twice rofl.

I've just made profiles that automatically set the clock to 1.5 when the screen turns on again and back to 1.5 when the screen turns off.
Edit*
Just tried the newest version and it failed to boot. Got stuck at the Google Logo. Here is the last_kmsg. Hopefully it helps
(had to put a .txt extension on it btw. Uploader wont let me upload w/o extension)
The Nexus 7 GPU is better than the Transformer Prime due to the faster RAM, so more bandwidth? If I'm correct? Thats why we see a higher Nenamark score at a lower clock?
This kernel looks very promising, excellent work! How much "play" have you had with upping the voltages, before the battery quits? On my TF, I can only go so far before the battery cannot provide enough juice, and it freezes on me. It would be interesting to know for people who want to OC really high. Does anything above 1.6 GHZ actually boot (heat and battery drainage aside)? It would be nice to OC up to 2.0 GHZ, if only for a proof-of concept. Finally, what are the temps you are getting on the higher clocks? It sounds like overheating may start becoming a real issue, and I was just curious.
The ram disk version rendered my tablet unbootable had to flash the Atlantis kernel from fast boot to get it back up and running.

Good work there, I would suggest adding Smartassv2 as well since it has been a good choice for many dev
I for the life of me can't get this kernel to OC. Tried System Tuner, Setcpu etc. Max only reads 1300mhz nothing shows higher beyond 1300. I have no clue what the deal is. I've tried wiping also. Even tried Atlantis' kernel. on his, it won't allow me to set anything. Max shows 0 and Min shows zero. I am running Pauls Modaco Jr3 and even tried it on EOS' new release. I'm beginning to wonder if its something diff internally. Anyone have any guesses?Also showing root as setcpu requests superuser permissions.

NOTICE: This is COMPATIBLE with ALL Google Rooted Stock and Custom ROMs based on JellyBean 4.2!
Just a statement regarding kernel source: The Kernel Source is of course covered under GPL version 2. Free software does NOT mean no work or time was spent working on it. I have donated a large sum of my free time to hack this kernel. If you use my modified kernel source in parts or in its entirety, I kindly ask you mention its origins and to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source. Thank you ![/b][/center]
Hi XDA members and fellow Nexus users:
This is my twenty-third kernel hack. I want to thank T0dbld, Turl and rest of my teammates, and several others I cannot recall for inspiring me to venture into this unfamiliar territory for me.
What is a Kernel? The Kernel is the Foundation in which everything else builds upon in any software system.
[Car Analogy]: Kernel is like the Engine, Electrical system and the Transmission to a car. The Library, Framework and the Apps [AKA ROM] are the body frame and the rest of the Car.
THIS KERNEL is BASED ON Google Source Code. So it is COMPATIBLE WITH ALL AOSP JB 4.2 Builds.
DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibility (Forced Close).
Kernel Features:
So what type of kernel is this? Well, this kernel is based on Linux 3.4.y (says so from the version string)
Features in Magenta are identical as the latest Linux 3.4+

Mirrors http://androidhosting.org/Devs/Faux/
Here's a step by step instruction to install this kernel:
1. download the above file (via phone directly or to a PC)
2. copy the downloaded zip file to /sdcard/download/
3. Open ROM Manager and select "Reboot into Recovery" and select "OK"
4. Once in recovery, select "wipe cache partition", select "Yes", then select "advanced", then select "Wipe Dalvik Cache", then select "Yes" again. Once finished, click the back button to go back to the main recovery menu. On that menu, select "Install Zip From SDCad", then select "Choose zip from SDCard", then go to /sdcard/download and select the downloaded zip file and let it run its script.
5. Once the script is done, select "reboot system now"
Note: After FLASHING, the first reboot may take longer than usual, please be patient... After the first reboot, it may lag during initial load (let everything finish loading). Once everything is loaded and phone is ready for use, reboot the phone a 2nd time and the lag will be gone and everything should be silky smooth...

FAQ:
1. Why don't my settings "stick" when using FauxClock App?
#1 issue with settings NOT sticking is superuser Switch to SuperSU should solve 95% of issues
https://play.google.com/store/apps/...51bGwsMSwxLDEsImV1LmNoYWluZmlyZS5zdXBlcnN1Il0.
UPDATE: Koush's new Superuser is also compatible with my apps!
2. Why doesn't my Max frequency settings NOT "stick" when using intellidemand governor with FauxClock App?
Intellidemand will AUTOMATICALLY UNDERCLOCK when there's a CONSTANT load for greater than 3 minutes. (Load spikes will NOT trigger the auto underclock, only CONSTANT loads). After the load is gone, it will restore back to original Max Clock. Constant load will drain the battery quite quickly, intellidemand governor will detect this behavior and automatically underclock to save more battery without ANY user intervention at all!
3. Why does the CPU freq slider move when I touch the screen?
Qualcomm's closed source mpdecision is the culprit. mpdecision raise the minimum CPU frequency to 1.026 GHz to "cheat" or increase UI smoothness. While this is a good idea, it is too aggressive and overkill causing unnecessary battery drains. And because it is closed sourced, it is NOT POSSIBLE to tweak its behaviors. I highly recommend turning off mpdecision when using my kernels in combination with intellidemand/intelli_plug
4. What is Intelli_plug? How do I use it?
Intelli_plug is my open source solution to Qualcomm's closed source mpdecision. Intelli_plug is enabled automatically upon boot, so NO need to turn on or off. However, it conflicts with mpdecsion, so I HIGHLY recommend turning off mpdecision when using my kernels! To turn off mpdecision, either use fauxclock app under CPU page or use terminal / init.d script and write "stop mpdecsion"
5. What is Eco Mode in FauxClock App?
Eco Mode is a special power savings mode part of the intelli_plug where the kernel automatically reconfigures its decisions in real time and optimizes to use only 2 out of 4 cores. Cores 3 and 4 are turned off completely.
6. My Gamma/Color settings do NOT stick when I removed FauxClock App from memory!
FauxClock app MUST be running to retain the colors. This is a limitation of the stock kernel and FauxClock app was designed to overcome this issue, so therefore it has to be running and be in memory (Avoid all Task Killers!!!)
7. If FauxClock has to be running all the time, does it CAUSE MORE DRAIN?
NO, FauxClock is a normal behaving app which does NOT HOLD or request ANY wakelocks from Android system. Therefore it does NOT cause any drain at all while running (matter of fact, it's suspended most of the time until it's needed)
8. What is "SnakeCharmer" ?
SnakeCharmer is an extension that I created to tame the Qualcomm Krait CPUs. Due to asynchronous SMP cpu design, each CPU can have its own independent min/max frequencies. SnakeCharmer allows you to set a specific max cpu frequency to all cores at the same time, so if you want to UNDERCLOCK your CPUs to a specific frequency, you should enable it under FauxClock.
9. I enabled "SnakeCharmer" but I occasionally see it still goes to max 1.512 GHz, why?
SnakeCharmer works flawlessly. FauxClock app is a Java app which runs on top of Linux. Sometimes it gets out of sync with the kernel, so it will display a frequency that's higher than the maximum "SnakeCharmer" frequency. This is a PURE DISPLAY issue with FauxClock App. SnakeCharmer works advertised! (Confirmed using CPUSpy by multiple users).
10. I have BOTH FauxClock and FauxDisplay apps but I seemed to lost the Screen Adjustment Tab under FauxClock? (Nexus 4 Only)
FauxDisplay (aka Advanced Gamma Control has full 27 controls unlocked, it supersedes the basic controls provided by FauxClock
11. What is Turbo Boost and how do I enable it? (Nexus 4 ONLY)
Turbo Boost is similar to Intel's Turbo Boost for the x86 CPUs. It increase the clock frequencies when 2 or less cores are active. (TB-U allows up to 1.9.44 GHz, TB-M allows up to 1.836 GHz). To enable turbo boost, simply slide the CPU max frequency slider all the way to the right!
12. Why can't I Undervolt below 600mv?
Ever since I created the UV interface for Qualcomm phones on 2010, 600mv minimum voltage has been chosen for a reason. There are typically 2~4 different "binnnings" for the same CPU chip (each binning has their own voltage tables) and therefore NOT ALL CHIPS are created equal. The 600mv limit was put through many different tests and was found to be stable ACROSS many many different chips/binnings combinations (No crash or sleep-of-death aka SOD) and it has been proven time and time again to be a good value for minimum voltage value.
SOC Sleep States demystified! (Corrected for incorrect information thanks for G+ comments!)
Often times users using many apps like CPU Spy will say post how much time their phone spent in "deep sleep" and thinking that "deep sleep" is only 1 state, unfortunately, it is WRONG. For many modern CPUs there are several C-States (sleep states), and the term "deep sleep" does NOT correctly describe them all.
Just like in real life, there are several stages of "sleep", the shallowest sleep is C0 State. As in real life, C0 state is very easy to wake up from with almost NO latency at all (real life will be like grogginess, so C0 is just like when you first doze off but any little distraction will instantly wake you up). The deeper the sleep, the harder it is to wake up from. It takes longer for CPU to re-initialize itself to a waking state (just like real life where once you enter REM sleep, it's very hard to wake up from it).
For most processors, C3 is the Deepest sleep state. C3 state is ALMOST like turning it off using the absolutely minimum power.
C0 - Shallowest sleep (dozing off) with instant wake up
C1 - slightly deeper sleep with slight latency when waking up
C2 - deeper sleep with longer latency when waking up
C3 - really deep sleep (like REM sleep in real life) with longest latency when waking up
My pyramid (Sensation 4G) kernel has Intellidemand Governor 2.0 (Grand daddy of the Mako's Intellidemand governor) where I disabled ALL hotplugging when screen is on (ie, both cores stays ON the WHOLE TIME) but I enabled C2 state for both processors, so even though at first you think it may draw more battery than hotplugging (turning off the core when not using), many of my users have experienced better battery life than with hotplugging (Hotplugging is VERY expensive, the act of turning cores on/off drains battery as well).
On Nexus 4 (Mako), for some reason, Qualcomm has decided to only allow for C0 state (the shallowest sleep) and so the "deep sleep" isn't really that deep. With my FauxClock app + my kernel, I give you all the "deeper" sleep states so when idling, you phone can experience deeper sleep. There's a hardware bug for Krait processors where the secondary cores, 1~3, cannot achieve deeper sleep state independently, so hotplugging is still necessary to save power for cores 1~3 but for core 0 (and core 0 is the master CPU and it's NEVER hotplugged) being able to go into deeper sleep state will help to conserve more power.
FauxClock is designed with forward compatibility. With the newer Qualcomm Krait 600/800 series, they have fixed a few of the hardware bugs from the Krait processors, and so for those newer SOCs, you can go into deeper sleep with all cores like the like older 8x60 SOCs.
Yea! Glad to see you came with me from the Amaze forums! Can't wait to flash soon!
I remember you from the hercules forums. Nice to see you here! Looking forward to using your kernels.
Well well well... Look who's here. Nice to see you working on This beast man. I'm excited to see what you have in store for us.

Also, doesnt run @ 1.8. Itll reboot and then hang till you reflash the kernel.
Pesonally I'd suggest staying away from this until it was a bit more tested.

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
Change "0" to "1" and safe the file to enable
Change "1" to "0" and safe the file to disable
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
1.12 Dynamic Fsync VS. Asynchronous Fsync
* 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.
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.

First of all, Thanks to @dtrail1 for the amazing kernel and all his hard work for the Razr community. If it was not for him, most of us would've moved on to some other phones.
What is this Thread for.?
This thread is for sharing/discussing your JBX settings/configuration you are running or played with. The only purpose is to have a better idea about the settings and help new users get a hold of it.
The original JBX thread is one of the most replied in the forums and its difficult to keep track of settings related questions, so I felt a need for this.
What its not.!
This is only for settings related questions or discussion. Not about other issues or problems. For those, refer to the original JBX Thread.. It has almost all questions covered and an awesome FAQ/Usage Guide.
When posting your settings.
Mention your ROM.
Mention the JBX build/version.
If possible include screenshots (like battery usage).

Mine,cannot say much about battery atm, as I went through rsd to get a complete fresh install tonight, but after first charge it seems a lot better!
Running pac 15.04 build and will not update the next week to get true results in battery.
This is my setup as I'm using it usually.
Edit : battery friend disabled and enabled ril build.prob tweaks, also net security and net speed tweaks from aroma installer installed.

U have to flash rom again before, then jbx and untick this option

I guess I should include a restore option for the 10% battery. Until next update you can just replace the Ramdisk.img located in /system/etc/kexec with that one located in your rom zip.

What about ktoonservative governor setting? why screen off sampling rate is higher than screen on? is lower sampling rate saves juice?

Running dynamic fsync since tonight,everything is good
Anyone else got random reboot and freeze with vr scheduler? Never had this before...

I'm not sure if I changed VR according to overall block changes. ROW is default again. After changes ROW is now the fastest one. (tested in system tuner Filesystem benchmark)

I have tested most configurations but ROW and KTOONSERVATIVE work the best.
Wakelocks still here
This thread is my chance to gather over 10 messages for joining to JBX kernel discussion in the development section.
I'm testing 16/04 JBX jointly with SlimKat 4.4 on my XT912 MAXX.
In my case ALL 3.0.31 JBX take wakelock incidentally and as result the device does not sleep. It only dozes on minimal frequency according to current settings.Doesn't matter what minimal frequency is used 100 or 300 MHz, hotplugging enabled or disabled, HDMI on or off. It happens. I'm using Trickster MOD to check deep sleep availability. I tick Warp Counters on Information tab then I push Power button and wait for 10-20 seconds. After that I power up my phone and refresh used states - Deep sleep remains within not used states. Only reboot helps.
Neither Wakelock detector nor BetterBatteryStats do not clear up who took a wakelock. Only the Battery statistic shows that Android OS keep the CPU awake.
For example if we look at screenshots from this post we will see that 300 MHz time is greater than Display time at least twice! I think it is abnormal.
Not very impressive, I think I S have to switch rom again, but I'll wait a few days more
Also 44 mins of calls and data on all time, 30 mins on 3g...

###########################################################################################################################
These kernel settings are dead! They will not be updated or worked on. Support has ended for them! If you want to keep using settings like this but that are better please switch to the Nebula Kernel!
Here is a link to the new kernel settings for the Nebula Kernel!
http://forum.xda-developers.com/lg-g3/general/kernel-settings-nebulakernel-rev10-2-1-t3258520
##############################################################################################################################
USE AT YOUR OWN RISK!! MIGHT NOT WORK FOR ALL G3!!
MAKE BACKUP OF YOUR DEVICE BEFORE USING THESE FILES!!!
Please Do not change or mod these settings or re-release them! If you do i will hunt you down and murder your favorite pet and turn them into a nice steak! [That was a joke......]
This thread is for setting i made for the LG G3 Verizon Wireless (vs985)
These settings are to be used with SetCPU and Trickster Mod (You'll need Trickster Mod donate pack to restore the Trickster Mod backup settings)
These settings .zip are not flashable. You will need to unzip the pack ON DEVICE.
PACK includes:
SetCPU profiles:
Multimedia - Other, Multimedia - Photos, Multimedia - Music, Multimedia - Video, Multimedia - Camera, Emulator- MyBoy!, Social, Google Chrome, GPS Navigation and Maps [NO ACTIVE], Phone/Contacts, HIGH TEMP!! 170+oF+!!, Games (HD-Large), Games (HD-Small), Charging (AC/USB), Screen Off, Everyday Use. Those are the profiles in the SetCPU pack. They are still being tweaked!
Trickster Mod Setting: EXTREME Undervolting, On_demand Governor tweaking, minfree_Control (RAM Management), 1512 i/o fiops, and some other awesome things! They are still being tweaked!
Install directions for these files:
1. Download the .zip file from this page
2. Unzip pack
3. Put the LG G3 CM12.x JediKernel 3.0 [1.x] [2.88GHz].setcpu.json in the root of your onboard SD card partition. SetCPU will find the files on its own when you go and restore it
4. Put the LG G3 (vs985) CM12.1 JediKernel 3.0 2.88GHz [09-19-2015] file in the tm_profiles folder in the on board SD card partition.
Then go into Trickster Mod and touch restore and select the latest version of the files
5. Download NOMone Resolution Changer and set your Resolution to 1080 x 1920 with the DPI settings of 320! This is just something i forgot to add! This will help you get MAXIMUM proformance and battery life since your display will not be pushing a 1440p resolution! LINK TO APP [https://play.google.com/store/apps/details?id=com.nomone.resolution_changer&hl=en]
6. ENJOY THESE FILES and you're instantly AWESOME LG G3!
I do not take ANY credit AT ALL for the making of the kernel! I did not build the KERNEL! All credit goes to @ptmr3 !
These settings ONLY work on the JediKernel! If you use the Trickster Mod Settings on any other kernel the device will crash and boot loop
DOWNLOAD THIS BADASS KERNEL FROM THIS BADASS DEV!
Kernel link: http://forum.xda-developers.com/ver.../kernel-jedikernel-g3-1-0-08-20-2015-t3183997
GeekBench scores in the image i added!
1. Single Core: 1115 | Multi Core: 3363
2. Single Core: 1071 | Multi Core 3502
[CHANGELOG]
09-12-2015: [V1.0 Stable]
1.Release of the pack!
2.Release pack date isn't current but it's the newest/latest build/compile of the settings pack.
09-18-2015: [V1.1 Stable]
1. SetCPU: Multimedia-Camera Added Open camera
2. SetCPU: Google Chrome lowered MAX CPU Freq from 1959MHz to 1728MHz for stability
3. Trickster Mod: Much needed CPU voltage tweaking! Now more stable but keeping extreme undervolting and keeping temp down and saving battery
4. Trickster Mod: OnDemand Governor tweaking. Now CPU and GPU play nicely together. If any lag or frame drops were in the last build it is most likely gone.
09-19-2015: [V1.2 Stable]
1. SetCPU: Nothing changed!
2. Trickster Mod: CPU voltages raised for more stability!
3. Trickster Mod: OnDemand Governor tweaked. Still testing can't tell if it drops performance or raised it up a bit!
09-19-2015: [V1.2-1 Stable]
1. Added Kernel Adiutor support! READ FILE INSTALL DIRECTIONS ABOVE! [STILL IN TESTING STAGE]
09-23-2015: [V1.3 STABLE]
1. Trickster Mods: Fixed CPU voltage setting for more system stability.
2. Trickster Mod: Reverted back to On Demand settings that were in V1.1!
3. SetCPU: No Change. Changes coming next version build release!
4. Kernel Adiutor: Turns out the settings i released for this app don't work. The file in this pack has not been updated nor does it work from what i have heard from a tester!
10-01-2015: [V1.4 STABLE]
1. Trickster Mod: Fixed CPU voltages! Its more stable now!
2. Trickster Mod: Updated On-Demand Governor! I tweaked the settings a little bit! The user can try the setting if they want! By default it is 0.2 but 0.3 is the testing settings (That is if it shows both!)
3. SetCPU: Multimedia - Video: Added Popcorn Time Remote
4. SetCPU: Google Chrome: Put MAX CPU freq/speed from 1728MHz to 1958MHz
5. SetCPU: Charging (AC/USB): Put MAX CPU freq/speed from 2572MHz to 2457MHz
6. SetCPU: Screen Off: Changed Governor from conservative to On Demand for better proformance when waking the display hopefully battery life will not change. Please change the Governor to conservative because On Demand drains a little battery. It sat in 268MHz for a hour because the Governor was being hyperactive!
7. GPU Navigation and Maps NOW enabled and added Maps (Google Maps) The reason it was disabled was because i was having issues with it not switching to profile when Google Maps was opened. Still testing this profile! Tell me if you got it to work and how!
11-08-2015: [V1.5 STABLE]
1.Trickster Mod: Fixed/tweaked the Voltages! The devices seems more stable for me but i still tweaking the to get the most out of the device!
2.Trickster Mod: The OnDemand Governor was tweaked but i'm still using the 0.2 version because it seems to be the most perfect for everything!
3. SetCPU: I made too many changes and upgrades to the profiles to be able to write them all down. I made to new profiles Games HD large and small.
11-11-2015: [V1.6 STABLE-TESTING]
1. SetCPU: Changed MAX CPU freq for Screen Off profile from 576MHz down to 499MHz
2. SetCPU: Added TrueCaller and TrueDialer to the Phone, Contacts profile
3. SetCPU: Tweaked some other small things that forgot.
4. Trickster Mod: Complete Redo/Remake of the already extreme under voltage settings! This is still be tweaked! Not 100% stable yet. I've had a few crashing while using my phone.
11-13-2015: [V1.6.1 STABLE-TESTING]
1. SetCPU: No changes. Comes with the same file that is in 1.6 STABLE-TESTING package
2. Trickster Mod: More speaking of the voltages. Still have crashing here and there but i'm still working on perfecting it!
SEE NEWEST/LATEST THREAD POST TO SEE THE VOLTAGE TABLE COMPARED TO STOCK VOLTAGES!
11-18-2015: [V1.6.2 STABLE-TESTING]
1. SetCPU: Camera: Changed Max frew from 1728 to 1958 and changed governor from conservative to OnDemand.
2. SetCPU: Multimedia Video: Changed Max freq from 1958 to 1728 because i kept getting crashing while playing YouTube videos in 720p 60FPS
3. SetCPU: Multimedia Music: Changed Max freq from 2265 to 1958 because i was getting better battery life with Google Play Music.
4. Trickster Mod: Tweaking of the voltages. It's a lot more stable now! I'm getting a whole day of battery life with light to medium use and still get 80% of battery at the end of the day!
Please report back after updating!
If you encounter any device crashing please tell me
Looks awesome bro, good work!

Thanks for sharing your setting.
Just a suggestion, but wouldn't it be easier to use Synapse and share the profile vs using two apps. Maybe you have your reasons so don't take this as anything other than me thinking out loud. :thumbup: :beer:

None taken! The reason I use these 2 apps are because Synapse is horrible! (My opinion) if you would perfery I can try to build my settings into that app for those who use it! Tomorrow I'll be releasing a new build of the files with much need tweaking.

Na man, no worries. Was more curious than anything. Synapse for me personally just has too many settings and for someone like me more ways to make a hot mess. Lol
I use kernel adiutor mainly because its baked into the rom and one less app I need to install.

After looking for a way to backup settings in kernel adiutor. i couldnt find a way to back them up. If you know how then please tell me! If i can back them i will upload them in the next update.
I'm not 100%, but this should be what to do...
In the app Tools/Profile/hit the + tab/tic select all or ?/ and it creates the settings profile
This part I'm willing to test with you. In your file explorer app go to the root tab.
/data/data/com.grarak.kerneladiutor/files/profiles.json
This is the profile you created. I'm assuming if I placed your file in the same folders on my device I would see the profile you created.

Well i can try them when im free! The thing is that you have to use the SetCPU profile settings along with the other settings.

What i did is i used a app called NOMone Resolution Changer to change the resolution to 1080p with the DPI to 320. Putting the resolution to 1080p helps in battery life and proformance!
I'm running CM12.1! Check out the JediROM! Its by the same dev that made the kernel! I don't use it but its still a great ROM! I prefer CM12.1 [I make the kernel settings]

Ah, yes. I've used that many times. Prefer to stay on 1440p due to the extra crispiness of the small text, but I have seen some small battery savings doing 1080p.
Thanks for your setup, I am playing around with it to tweak to my liking.
