"Self determination is NOT a malfunction" -Harkness (Android A3-21)
This kernel is experimental. All patches used, source code, etc. can be found here with as many of the original authors intact as possible.
***ONLY RECENT (aka inline with CMs display drivers) AOSP-BASED ROMS SUPPORTED***
FEATURES:
- based off of Cyanogenmod's 3.4.y kernel
- compiled using Sourcery CodeBench Lite GCC 4.7 toolchain (-Os)
- floating-point & graphite loop optimizations
- cleaned up some modules and debugging
- Tweaked GPIO debounce timing [Increased vol. long press]
- Increased touchscreen sensitivity
- dkp notification/backlight LED fade animations (DecimalMan)
- faux sound support
- patches from a plethora of sources (including franciscofranco, WillDeacon, ConKolihas, etc.)
- fast charge capable (imoseyon)
- UV capable (faux123)
- full sched-deadline implementation (jlelli)
- semaphore n4's conservative & ondemand driver (stratosk)
- Power efficient workqueues (Linaro)
- Plenty of backports from mainline [sched, cpuidle, random, smp, etc.] (Linux)
- asm-generic rwsem (Will Deacon)
- Imports from Motorola's msm kernel source:
* always update vfp_current_hw_state when forcing reloading
* fixup to allow sched to play nice with CPU_HOTPLUG
* Krait memutils
* acpuclock-krait: init to max speed (improve boot time)
* lmk/compaction: updates to allow improved/stricter memory management
- I'll add more as I remember
BUG REPORTS:
Please include a kmsg/dmesg to any bug reports: http://code.google.com/p/tegraowners-ics-rom/wiki/How_to_get_logs
If you you are unable to do so for whatever reason, try to use as much detail as possible and give me a way to replicate it, so that I may attempt to log it. Thanks!
NOTES:
- Reserved for notes about bugs.
- Cleared since we seem to be golden with trickstermod and I have yet to have a recent cm build fail on init. Let me know if you find anything.
SCHED_DEADLINE:
Not to be confused with the iosched deadline, Sched_deadline is a scheduling class that implements a real-time CPU scheduling algorithm; EDF (Earliest Deadline First), augmented with a bandwidth isolation mechanism (called Constant Bandwidth Server, CBS) that makes it possible to isolate the behaviour of tasks between each other. SCHED_DEADLINE allows the CPU to reserve a portion of the CPU time to a specific application very accurately. A key feature is that it ensures "temporal isolation", which means that the temporal behavior of each task (i.e., its ability to meet its deadlines) is not affected by the behavior of any other task in the system. In other words, even if a task misbehaves, it is not able to exploit larger execution times than the amount it has been allocated. When a task tries to execute more than its budget, it is slowed down, by stopping it until the time instant of its next deadline. When, at that time, it is made runnable again, its budget is refilled and a new deadline is computed.
POWER EFFICIENT WORKQUEUES:
With per-cpu workqueues, the scheduler considers a CPU idle if it doesn't have any task to execute and tries to keep idle cores idle to conserve power; however, for example, a per-cpu work item scheduled from an interrupt handler on an idle CPU will force the scheduler to excute the work item on that CPU breaking the idleness. Power efficient workqueues are allowed to be unbound, meaning they are not forced to queue up on what could be an idle CPU; instead, the scheduler allows work to be rescheduled on a core that is already awake.
SEMAPHORE ONDEMAND TUNABLES:
touch_load: the simulated load when there is a touch on screen (default 75)
touch_load_threshold: over this load the touch_load will be applied (default 10)
touch_load_duration: the duration of the simulated load in msec (default 1100)
VOLTAGE TABLES/BINNING:
What CPU do you have? Nominal, Fast ...or Slow
The phones with the lower default voltage values use the "fast" 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. 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.
commandline:
adb shell dmesg | grep PVS
(acpuclk-krait in our kernel defines PVS as id numbers)
acpuclk-8960: ACPU PVS: 0 = Slow
-or-
acpuclk-8960: ACPU PVS: 1 = Nominal
-or-
acpuclk-8960: ACPU PVS: 3 = Fast
- thanks to _motley for this awesome write-up on his kernel/kernel features... and for providing explicit detail on his works
A Note for Developers:
CODEBENCH COMPILE CACHING:
Ccache is commonly used to reduce compile times for C-related files. CodeBench's toolchains utilize their very own compile caching that works EXTREMELY well. You MUST be on at least the 5-23 version of CodeBench (CodeBench Lite can be found here). The related patch for using this feature will be posted below. Examples of use are in the commit message.
Basic CS cache patch
Please pull request any improvements/post discussion.
I'll add more info about key features as I work along.

Thanks, trying it out now. Would you recommend to have mpdecision enabled or my own oc/uv? Also deepsleep state is unused is that normal? I may have tinkered with the trickster settings too much haha
Also using slim bean v6
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
I personally disable mpdecision (dont even have it in my rom builds at all). Also my device deep sleeps fairly quickly given the right circumstances (i.e. no wakelocks caused by music, etc.). You can try BetterBatteryStats/Greenify to see whats causing your device to be unable to sleep.

Just had to chime in and say that this kernel is AWESOME. It's been a long time since I used a custom kernel; Franco's was the last that I used on my Galaxy Nexus.
Thanks for this!!!

I had the same thing last night. Glad youve found a solution; you can try Greenify and see if it helps you find your problem:
Slept like a baby in a matter of seconds after I shut off the screen and set slacker to hibernate.
I've got some ideas as to what it might be but I want to try getting some sched stats to see if I can get a better idea before I start blaming things lol. I'll do what I can to keep you posted, but if you don't mind, I would also like to see what wakelocks you have (if any) on greenify.

INFOBFS (Brain **** Scheduler):
BFS: The objective of BFS, compared to other schedulers, was to provide a scheduler with a simpler algorithm, that did not require adjustment of heuristics or tuning parameters to tailor performance to a specific type of computation workload. The BFS author asserted that these tunable parameters were difficult for the average user to understand, especially in terms of interactions of multiple parameters with each other, and claimed that the use of such tuning parameters could often result in improved performance in a specific targeted type of computation, at the cost of worse performance in the general case.[4] BFS has been reported to improve responsiveness on light-NUMA (non-uniform memory access) Linux mobile devices and desktop computers with fewer than 16 cores.
Information Source: http://en.wikipedia.org/wiki/Brain_Fuck_Scheduler & http://ck.kolivas.org/patches/bfs/bfs-faq.txt
Swap:
Swap: Swap is a way to extend your physical memory. The OS moves the less accessed memory pages to slower, and cheaper storage medium. This frees up RAM for things that require the speed.
Governors:
demonspeed! Governor: this governor is rather similar to the 'ondemand' governor both in its source code and its purpose, the difference is its optimisation for better suitability in a battery powered environment. The frequency is gracefully increased and decreased rather than jumping to 100% when speed is required. Based off a lag free concept, with screen off profiles built in. demonspeed has not been tested against battery life performance, but rather for speed and user interaction.
[*]SuperBad Governor: A "superbad" super smooth rendition of a highly optimized "smartass" governor! Low latency and more responive to the user.
[*]SCARY Governor (@Scaryghoul): Scary - A new governor Scaryghoul wrote based on conservative with some smartass features, it scales accordingly to conservatives laws. So it will start from the bottom, take a load sample, if it's above the upthreshold, ramp up only one speed at a time, and ramp down one at a time. It will automatically cap the off screen speeds to 245Mhz, and if your min freq is higher than 245mhz, it will reset the min to 120mhz while screen is off and restore it upon screen awakening, and still scale accordingly to conservatives laws. So it spends most of its time at lower frequencies. The goal of this is to get the best battery life with decent performance. It will give the same performance as conservative right now, it will get tweaked over time.
I/O Schedulers:
V(R) I/O Scheduler: V(R) is similar to, and based on, Linux's deadline I/O scheduler. It implements request deadlines which try to limit starvation, but provide no hard guarantee of request latency. It also merges and batches requests in a similar manner, but unlike deadline, read and write requests are issued together. This means there is no preference to reads over writes. Thus, higher throughput can be achieved at the cost of interactive performance. Secondly, V(R) could be used for situations where maximal throughput it the primary concern, such as batch processing systems, where per-request latency is not important. By scheduling read and write requests together and setting sufficiently high deadlines, V(R) can theoretically produce a better schedule than deadline, AS or CFQ.
RCU SubSystem:
RCU Concept: The basic idea behind RCU (read-copy update) is to split destructive operations into two parts, one that prevents anyone from seeing the data item being destroyed, and one that actually carries out the destruction. A "grace period" must elapse between the two parts, and this grace period must be long enough that any readers accessing the item being deleted have since dropped their references. For example, an RCU-protected deletion from a linked list would first remove the item from the list, wait for a grace period to elapse, then free the element. See the listRCU.txt file for more information on using RCU with linked lists.

Tiny Preempt RCU: This implements a small-memory-footprint uniprocessor-only implementation of preemptible RCU. This implementation uses but a single blocked-tasks list rather than the combinatorial number used per leaf rcu_node by TREE_PREEMPT_RCU, which reduces memory consumption and greatly simplifies processing. This version also takes advantage of uniprocessor execution to accelerate grace periods in the case where there are no readers. The general design is otherwise broadly similar to that of TREE_PREEMPT_RCU.

So I flashed and reflashed this kernel last night and didn't see any option for Scary in setcpu (am I misssing something)?
Also my battery drained way faster than normal. I manually set it to 245/902 and had slacker radio on a 15 minute timer as I fell asleep which is what I do most nights. This morning I wake up and battery is under 15%...hmmmm.
Ideas?

Yes that is the idea...
Going to be adding some more instructions to my op. Before flashing the new kernel make sure all features of setcpu are disabled, for example, set on boot and profilres... flash the kernel.. let it reboot and give it a few minutes and then rebbot again... after rebooting for the second time, if u use setcpu, go in and select auto detect freq.

Ok, I was on 0.5...just updated to 0.6...Let's see how it goes! Thanks
i think im having a battery drain issue....i charged my phone too 100 then i went to bed and now its at 60% and i havnt even touched the phone. I have it on scary also.on the regular i have been able to use my phone for 12 hours and be at 80-60% after 12 hours...so i think something is wrong.

Thanx for the feedback. Since scary gov is new and I haven't tested it that long, it may or may not be causing some battery drain.. I will look into it... but jjust for a note I went to bed last night @ 58% and woke up 7 hrs later @ 56%... but the more feedback I get from more ppl the better..

AOKPX is an open-source project based off of aokp; started by existz, with goals of simplicity, smoothness and optimization.
Updates are dependent on things such as time between builds, changes between builds, time I have available, etc. I'll usually let everyone have a bit of time to let the rom settle in before pushing an update.
Rules:
-Don't ask for ETA's please
-Don't be a jerk to other users in my thread (we were all newbies once)
-Until notified otherwise, this is a work in progress; what you see is what you get
-We are not responsible for anything you decide to do to your own device... you have been warned
-As long as everyone is being helpful and efforts are being made to properly debug; I could care less about some of the topics going on in this thread. I find android a lot more enjoyable to work on when I'm not nagging you constantly to post in another thread.
Features:
-Based off of aokp jb-mr1 source code
-Compiled from existz' aokpx source (linked below)
-Patches, optimizations, and updates from Linaro, CodeAurora and CM (and more!)
-ODEXED for speed (many ways to deodex if you want to decompile anything for any reason)
-Compiled with AOSP gcc-4.7 toolchain using recent OpenJDK builds, compiled locally (jdk7u-dev source: http://hg.openjdk.java.net/jdk7u/jdk7u-dev)
*Current OpenJDK Build: https://github.com/aokpx/platform_prebuilts_openjdk-Custom 3.4.x Cyanogenmod-based Harkness kernel (jb-mr1 source)
Kernel Features:
*Faux-Sound ready
*Fast-charge support
*Enhanced thermal control for krait CPU's by _motley (tunable; /sys/module/msm_thermal)
*Autohotplug by Thalamus and enhanced by _motley (tunable; /sys/module/auto_hotplug)
*Slightly enhanced interactive governor; works with autohotplug boostpulse & input_boost_freq userspace tunable
*Configurable color temp.
*Userspace voltage control
*HAVE_EFFICIENT_UNALIGNED_ACCESS enabled; w/ optimizations beneficial to LZO decompression
*Patches/Tweaks from around XDA (from upstream CM, around the d2 sections and other krait device(s)
*(see source)
Bugs:
-Creating stations (Pandora)
-All the things in aokp
Read here to find out about getting logs. (Logs are needed if you want to be helped properly).

Kernel Info:
Thermal Throttling and Hotplug Control
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.
To adjust sysfs values through terminal, use:
Code:
[B]echo[/B] [I]value[/I] [B]>[/B] [I]path/to/file[/I]
A lot of these tunables are exposed and compatible with Trickster MOD; if you want an app that can easily adjust these sysfs values via user-friendly interface.
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. _motley has taken _thalamus' base (thanks!) and 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
[NOTE: this is a no-op for us, since we only have 2 cores to use, anyway; enable load threshold is good enough]
Load at which all CPU's are enabled, 270-550, default is 200 (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, 1-2, default 2 (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, 1-2, default 1 (tune up for performance/bench-marking):
Code:
/sys/module/auto_hotplug/parameters/min_online_cpus
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. 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-krait in our kernel defines PVS as id numbers)
acpuclk-8960: ACPU PVS: 0 = Slow
-or-
acpuclk-8960: ACPU PVS: 1 = Nominal
-or-
acpuclk-8960: ACPU PVS: 3 = Fast
-or-
acpuclk-8960: ACPU PVS: 4 = Faster

They call me JAM because YOU'RE jelly, bro (there's that one dude that seems to always put the first post with his silly tag about why they call him jelly )
EDIT: So, your description is pretty brief - does this ROM have working tether? Could you put a link in the OP to an option for inverted apps? Which camera(s) it come with? Are there a bunch of features you're leaving off the list? What makes THIS ROM better than the others? And last but not least, thanks for all your hard work!

It's heavily based on aokp and was mainly used as a quick setup for existz. I built it for myself, pulled in some more patches from CAF to the kernel and other places (hardware/qcom) and once I was satisfied with it, I thought I would share. So, essentially most things in aokp should be here too... Nothing all that special yet as existz has been too busy to even provide user support and I'm still settling into my new home. I'd work more on things that were broken (a2dp in paticular) but my car got broken into on new years eve and my method of testing that was stolen :/ but it seems it was fixed upstream; though as I said, I can't test that anymore . It comes with the stock aokp camera and sure I can look up a link some time for those inverted gapps lol.

USB Tethering is definitely working, Wi-Fi tethering I couldn't get working. Rom is running very well for me otherwise. coming from kang 1/23/13 nightly, this rom seems possibly faster (could just be my "flash" addiction)
eXistZ's rom was by far my favorite on my Inspire 4g so I was excited to see something with his name on it for my S3. He's still providing some of the best work out there, fast and stable and simple.
Voice search FC'd on me a few times until I updated now it works great. GPS was a little wonky but seems fine now after a couple of reboots.

Oh right I meant to add the part about Google Search to the op. Just got that added in though thanks for reminding me. As for GPS, I think that partially depends on where you're at because in Houston I can get a lock quickly but here in San Marcos i have a bit more trouble getting a lock.

Those were commits from upstream (AOKP). I don't use FM radio so I didn't test for that. Though I think I remember seeing similar patches in cm saying that there were problems on msm8960. Thanks for reporting though. This way I'll have a better idea as to what does/doesn't work beyond whats used by me... And I can make a few more notes one what needs working on other than "all the things in aokp"

It includes a lot of commits from CAF, AOSP master, Linaro and various other places. Its also built using GCC 4.7, plus full source is compiled with O3 and strict aliasing optimizations (and skia is compiled with Graphite optimizations), along with various ARM/NEON optimizations. Plus tons of other stuff through out the source...And also the ROM is built using OpenJDK 7 (instead of Java 6). That's just the changes I've made, not counting whatever SGS3 specifics from Synthetic

Re: [ROM][4.2.1][02/07/13]aokpX-d2tmo[JOP40G]
I looked around a little, but couldn't find anything on this. In call volume doesn't work, meaning that using the volume controls during a phone call doesn't adjust the volume. Also, I couldn't find a list of what's not working in AOKP. Maybe I missed something.

*if you come from faux or tbalden please reflash your rom, you don''t need a wipe. They have some trickery with their own hotplugs so they have reomved mpdecision, so without reflashing your phone will be stuck on quad core*
4. Flash kernel
5. Reboot
*Please let it sit for ~10 mins before judging as it will need to settle down. Do not judge battery life unless you've run it through at least 3+ cycles after flashing*

DISCLAIMERS:
1) Excessive under/overvolting can cause damage to the internal parts of your phone. It can cause the phone's lifespan to deteriorate quickly so make sure you know boundaries
2) If you OC'ed/OV'ed/UV'ed and now are in a boot loop or your phone is slow, or acting weird or just died - it means your phone does not like the changes. Voltage control is for those who know what the risks are, know what they are doing and know how to fix it. Perhaps when you change these, test them for an hour or so before setting on boot
3) Any changes to the phone, including flashing the kernel itself is done at your own risk.
4) Every phone is differentt
5) Please DO NOT use any task killers (or additional init.d scripts), they DO NOT improve performance/battery. The kernel is designed to be used with stock settings: my settings and anything else can cause problems

Yes, since its the same kernel basically and same device Depends on what you want though, thats why the control script is able to set most things on boot without apps

So this is still compatible with apps that control cpu, gpu, etc. correct such as trickster? I am planning to use this kernel with the stock sense 6 rom odexed made from Joelz that was just posted in this forum just so you know so i can report how this kernel runs :good:

Sort of. Since pnpmgr is enabled (HTC power and performance manager) it means you can't set freqs in an app. You need to use the script if you want to control freqs
Governors, schedulers, 2w etc will stick only the frequencies will not stick
It's done like this because HTC developed the pnpmgr for smoothness, and disabling it will introduce stutter
The latest script is in the last page of my international thread

Thanks for this Kernel! I'm excited to try it. Just a question on the CPU frequencies, thus far I've always used TricksterMOD since I don't know how to mess around with "script" and all that mumbo jumbo...just wanted to make sure I got this right, to set our CPU frequencies we have to set the number values in that scrip and then flash?

Your warranty is now void.
I am not responsible for bricked devices, dead SD cards, thermonuclear war.
Please do some research if you have any concerns about using custom ROMs/Kernels.
You are choosing to make these modifications, and if you point the finger at me for
messing up your device, I will laugh at you.
Lambda Kernel is a CAF recreation of the LG G2's Kernel written for CAF based custom ROMs. It fits the needs of anyone looking for a decent performance/battery rate, being totally compatible with up to the newest Android 7.1 ROMs and all the way down to Android 5.1 ROMs using the wildcard concept.
It follows the flash n' go principle, everything packed in the Kernel is already tweaked and ready to be used as a daily driver for most users.
The downloads, contributors and source code are at the bottom of this post, it is recommended to read everything before flashing.
"The Lambda Kernel project was born as a reasonable alternative for non-lge firmware users that would enjoy having a decent operational system on their devices but, unfortunately, weren't possible because of the lack of a great Kernel for this panorama. That was a paradoxical paradigm, such a powerful device tied by controversial chains.
As a hobbyist and enthusiast, stepping forward on this was a must. Having the tools and one of the greatest kernels in the Android world at my side (dorimanx), sharing the same platform and device, I couldn't hesitate so long. Although we may never hit his level, it's worth mentioning this project has its own philosophy and purpose. Constructing a different way of thinking is always a pleasure."
"Everything that is yours needs to be controlled by anybody else than you. When flashing this kernel on a custom firmware, you'll be signing an authority term over your device possession. You'll be breaking chains imposed by a society niche that is closed source, proprietary and arrogant. They are the world that superimposes your look to keep you from seeing the Truth. The Truth that you are a slave. Like all the others you were born in chains. The world is a prison where there is neither hope nor taste nor smell, a prison for your mind. But still there's only one hope, there's only one way out: K.I.S.S. to maintain your own rules, to avoid unnecessary complexity in your escape."
The releases follow an organized naming scheme, alphabetically ordinary using portuguese words.
The current release name is Infinito.
Also, they follow a two-week basis schedule in the BETA stages in order to pack the latest security updates and code improvements. The STABLE ones don't have a schedule in mind, they are meant to be released after the BETA ones get 100% debugged and tested.
EXPERIMENTAL: My own testing builds for certain features and tests. They have numbers and comments in their versioning according to the consecutive builds I build and the latest changes in which I should look into testing. They aren't normally shared, although sometimes I publish them. If you see one of them, don't forget they are recommended for advanced users/developers only because of their potential changes that must be debugged before publishing a beta/stable version.
BETA: They are closer to the proper release version but still can have some errors or bugs to be reported and tested, they also have a number to avoid confusion. It's most likely what you'll be flashing in order to catch up with the latest code base and security updates.
STABLE: That's the version for the ones that don't want their devices to be lab rats for new features and staging changes. It might have some little issues but it's generally able to fill all user needs in terms of stability for such a bleeding-edge project.
Pretty straightforward once you get used to it, isn't it?

General updates in Synapse UI to match the new features EXTRA
AnyKernel2 ↠ It's the main feature of this kernel, it doesn't only make our lives easier by avoiding the usage of ramdisk but also let us change and ship many new features without touching the ROM side. Another great point on AnyKernel usage is the ability to setup your device on boot up, setting the governors and values that we love right out of the box without any kind of pain.
UCI/UKM ↠ UCI is a binary that allows Synapse access to control and manage the kernel's core. UKM is the component that allows prebuilt .json modules to build the Synapse UI without compiling the app on Android Studio or other Android IDE. You won't need to install a new version of the app from somewhere to get up-to-date, the kernel will automagically ship the changes I made in Synapse UI and apply them on the fly.
Linux 3.4.113 ↠ As you may know, your phone a ton of electronic hardware such as SmartTVs, printers, laptops, watches and even glasses run the Linux kernel. If you wanna know more about the Linux kernel, please watch this video on YouTube. The 3.4.113 version of the Linux kernel has been finished in Oct 26, 2016 and it's currently marked as EOL (End of Life) version.
MSM Hotplug ↠ This driver was coded by neobuddy. It is the chosen one to be the default hotplugging mechanism, supplying a nice range of options and a feature that dialogs directly with impulse governor called 'fast lane'. This feature will jump all cores into a speed trail when the CPU governor detects a high load average, thus reducing pressure on the main cores and improving performance.
Bricked Hotplug ↠ One of the recommended hotplug drivers. It was first coded by showp1984, now it is marginally cleaner and faster with neobuddy updates on top of it. It's a very complex hotplug but supplies one of the most stable hotplugging mechanism for any mobile Linux Kernel. Should be used in case the user wants total control on every bit of the plugging mechanism.
AutoSMP ↠ Yet another hotplugging, this one is focused on stability and fair resource usage, it's very minimal and offers bare minimal sets of controls. Should be used on user cases where battery life is the main target or just as a simple alternative to bricked hotplug.
Dual Core CPU Boosting ↠ This driver was coded by sultanxda for the Oneplus One recently. It allows a dynamic CPU boosting based on user input and hotplug activity. I have tweaked it to boost the first CPU to 1.2GHz for 1.5s on user input if the second CPU is already awake, if not it will then boost the second one to 1.4GHz for 1.5s as well. If the second CPU needs to stay online due to hotplug load, it will stay boosting the first CPU if the input is detected and if the frequency doesn't pass the threshold it will let the hotplug and governor decide what to do.
Dorimanx Fast Charger ↠ The fast charger driver that dorimanx uses on his kernel. Allows the configuration of the charging scheme, you can set from 500mV to 2000mV charging levels. The cable and charger will affect the charging level as well, don't use any charger/cable you found in the garbage can. I'm not responsible for the bad usage of this feature. Neither dorimanx, it's absolutely your fault if you damage your device.
Swap ↠ The Linux swap is very old and consolidate way of getting more RAM by caching older process and instances to a cached space out of the RAM space. This feature was common on servers but sooner came to the Android mobile devices as well. The swap space is usually not present in most devices as it costs more CPU power to "swap" the "files" from real RAM memory to another place, this place can be a hard drive partition, a portion the real RAM itself (Z-RAM) or even a file in some cases.
Z-RAM ↠ Another form of swap, commonly used on some Android phones due to higher CPU levels of instrumentation provided by ARM, in which we can same memory not by placing the caches to another place like a usual swap but compressing it in runtime as more instances and processes request real memory. As a note, Z-RAM has something called max compression streams, which are the maximum amount of parallel writes to the "new area", we set one per every 256MB of Z-RAM space, the default is 512MB of space compressed with two compression streams to keep power/battery compensation.
Faux Sound Control ↠ This driver, written by Faux, exposes the Kernel sound driver (WCD9320) to allow fine tuning from userspace, instead of the default static values they were set by the manufacturer. The fine tuning happens using two different APIs on my Kernel, one written for the proprietary app by Faux and another one by dorimanx, for STweaks. I've modified the STweaks scripts to add them on Synapse, calling it Synapse API for users that don't want to buy/use the proprietary app. The open Synapse API is capable of tuning the headphone, speaker and microphone gains without distortion since the magic happens in Kernel level and not in software level.

Q. Can I flash this Kernel on Android Lollipop?
A. Yes and no, only Android 5.1, 6.0, 7.0 and 7.1 are supported natively.
Q. Is this kernel compatible with LG stock firmware/ROM?
A. No, LG stock is Android 5.0 and already has dorimanx Kernel support, Lambda is only for targets in the answer above, custom ROMs commonly.
Q. What are variants on the LG G2 development scheme?
A. As many crap carriers on the market, LG is known to implement region based hardware, this causes the existence of series of devices that are identical but have some differences in terms of hardware. This forces developers to adapt and recreate the device trees for every single model.
Q. How to install this kernel?
A. Download the version you'd like to use and flash using a custom recovery like TWRP.
Q. I have an error in red when flashing the zip file, what is that?
A. Maybe your download was corrupted somehow, try to download once again.
Q. I have a "device not supported, aborting..". error in TWRP, what is wrong?
A. Your firmware/ROM's build.prop property 'ro.product.device' may have been modified and doesn't match the device filter protection implemented in TWRP. Ask your firmware/ROM's developer why he did this or post the value for 'ro.product.device' entry. Last but not impossible, the variant you have isn't supported like the ISAI variant family.
Q. I noticed the Synapse UI is so old-school, why can't I use Kernel Adiutor?
A. You can, but that would waste all the time I spent making UKM (read in details) unique for this kernel. You won't be able to use all the guts properly either. So, please don't use Adiutor as main Kernel Tweaking app, you can use it as a fallback option to see the frequencies and etc.
Q. I have problems to restore my settings with Synapse. What to do?
A. Well, this can be many things. The usual gripe happens when the bare ROM has an updated version of toybox and thus some busybox commands end up not working well. What I'd try at first glance is open it, to to TOOLS and tap Reset Synapse to clear the databases. Then, I'd open it again, dismiss any message on the screen and start tuning it to create the proper new database. After this, I'd export my config in SETUP just to save it for later and Reload Synapse. This usually works for most users...
Q. Why SELinux is set to permissive?
A. Some mods request the usage of permissive policies to work properly, it was needed to please everyone who had the mods before flashing the Kernel. You can always turn SELinux to enforcing in Synapse.

Can it survive nightlies?
If not, can it be done?
I Know someone made xposed cm 13 survival script so If its not,
It might be a good idea..

CM installs their Kernel over it by default, I think we can do something to back it up and reinstall but still CM side.

Awesome! I've been using CM13 (nightly) for over a week now and its been really good. Looking forward to your optimizations/tweaks/fixes/gadgets !
Maybe put "CM13" in your title.

It uses anykernel, so that means it will boot on more than just "cm13"

Might fit any LP-CAF ROM running their trees up-to-date, as far as I can see CM13 branch does nothing but update CM12.1 branch, so should run on 5.1, 6.0 and above. Needs testing though.

@GalaticStryder so far, so good. It's running great here on the LS980. It gets a little hotter than I'm use to, but it's so far, really fast and stable.
@GalaticStryder
I am glad you are back mate.
The kernel works perfectly with AICP 11 Rom on my D802, it is smooth and fast (read better than stock ketnel).
I am excited about the future of this project, great start!
P.S. I hope that you are going to be back soon to the rom development also!
I can find download section

Thanks, unfortunately, I'm not on the mood for ROM development, it's a lot more time demand and complaints... so far dealing with the heart of the monster is away healthier cause I do these stuff as a hobby. Maybe vacation will let me cook some fully AOSP builds as unique.

I'll upload the kernel setup I'm using as well as some defaults I tested on the second post.
I'm getting an average of:
45°C on CPU when installing apps, updating, downloading... and 38~40°C when the screen is on.
Battery Temperature is 32°C sticky.
Right now is 23°C by the morning (GMT -3) summer temps.

Now i see the problem, fauxsound gets louder after every reboot. Anyone to fix this? Can't really lower it anymore. Lol

It's not loud that's the way it should be but a little over, you need to adjust the ux volume to 7 or 8 of 10, 9 and 10 distort, but it is, in my case, better than not hearing the calls. I'll readjust in the next release. Thanks for confirming that issue. I'll clean up the Sound Driver code a bit as well.

Hi all,
I deleted all my old projects because i wasnt quite happy with them, so i created this kernel called Private Kernel because i thought i completly stop development on xda because downloads were quite low and decreasing from version to version. But now i am back with this kernel, i hope you enjoy it. I hope i did not do any mistakes with devDB
CAF Feature differences to his kernel:
* francos thermal driver tuned to work with the VADC sensor (more accurate throttling results)
* not underclocked by default
* added more ioschedulers (BFQ default)
* cpuquiet hotplug
* compiled with uber linaro toolchain
* some small various tweaks etc....
Only for roms with sultans CAF kernel! I dont support any weird combinations of camera hal's blobs and drivers.
CM13-Nightly Kernel features:
* francos thermal driver tuned to work with the VADC sensor (more accurate throttling results)
* tuned the BFQ I/O scheduler
* powerd my msm_hotplug
* synced with googles android 3.4 branch
* KCAL
* compiled with uber linaro toolchain
* CPU undervolt feature
* added the 268mhz CPU frequency
* some small various tweaks etc....
Tested on cm13 nightlys. I dont support any weird combinations of camera hal's blobs and drivers.

r2 Changelog:
* added voltage Control
* added Smartmax governor
* cleaned up smartmax governor
* removed boosting function from smartmax governor because we are using cpu_input_boost for that
* removed the redundant iowait check adapted for smartmax
Code:
"Iowait_time check is redundant and it would lead to heavy load
due to miscaluculation of idle time. Hence remove this check
as iowait will considered based on io_busy flag."
r3 Changelog:
* upstream updates from sultanxda
* added some compiler optimizations -O3 and some special ones for our soc
* added sound control
* reduced retention voltage (better idle drain during c states)
* disabled add random because it is only used on spinning devices and useless on flash devices
* lowered GPU voltage constraints
* reduced some debug logs to avoid a watchdog bite
* increased msm mpdec idle frequency slightly and avoid cores unlocking unnecessary when the cpu input boost driver is working
* smartmax default for now (i achieved good results with it)
r4 Changelog:
* synced with sultanxda
* re-added and updated ondemand governor (default)
* tuned smartmax to be slightly more aggressive
* updated interactive to a more recent version
* added lz4 compression and decompression --> a slightly larger kernel with decreased boot time
* added a small patch that should increase your ext4 filesystem performance
* updated anykernel ramdisk to the latest version
dont wonder if you get a busybox error it is a harmless warning!
r5 Changelog:
* improved the performance of bfq ioscheduler
* increased modem stability
* removed ondemand
* reverted back to the old interactive and ondemand
* added and modified autosmp hotplug (enabled by default)
* compiled with linaro 5.2 toolchain
* fixed some compilation warning introduced by gcc 5
* removed some unused things on our device (picked from cm kernel)
r6 Changelog:
* mpdecision active by default (it isnt actually that bad as i thought)
* removed bricked hotplug
* added f2fs support (experimental! i dont give support for it)
* some various patches from franciscofranco and cm to improve performance and fix some bugs
* updated cubic tcp (enabled by default)
* synced with CAF LA.BF.1.1.3_rb1.11

Thanks. I was waiting for a simplistic CAF kernel with just optimizations for a while now.
Kernel fast & smooth but in me the wifi is switch off by itself while idle
And for the battery compared to stock darkobas I feel this kernel got more long lasting one
Working well with CAF Temasek. Very smooth! Are we allowed to give feature request? If so, I'd like to request CPU voltage tuning. Thanks
Two cores always online by default?
Flashed on BrokenOS 6.0 and working well... Hope you'll add CPU govns in feature builds.

The wifi driver is exactly the same like on sultans stock kernel. Your problem must be with darkobas stock kernel, too. And i am sure that your wifi problem is rom related. I get 4 - 5 hours SOT on MM.

naveenjohnsonv said:

Yes this is the design of my hotplug. We have 4 cores on our device core0 core1 core2 core3. And core1 is always be onlined and offlined all the time and this eats up your battery.
"Every time a core gets kicked in, there have some calculations to be made, which needs battery. Onlining a core also needs some battery every time. You're using your device and cores are getting kicked in and out, because you have some more idle phase and some more heavy load phase.
Remember also that even if all cores are online, it doesnt mean a core cant enter a battery saving idle state if it doesnt have anything to do.
Online doesnt mean the core is active the whole time, it just doesnt get kicked out, which in the end is best for low latencies. The higher the idle state, the more time it needs to get active again. But its always faster than getting kicked out."

Sounds great �� Thanks. Working perfectly well.
@DerRomtester glad to see you back! I've never used your kernels before (my apologies!). I tend to use stock kernel to test ROMs. I also know how you feel when downloads time and again decrease and never increase. But trust me, there will always be someone that appreciates what you do. I know this is a CAF kernel but if you have the time, I suggest you give the latest OxygenOS 2.1.4 a spin. I know its not the latest OS or the most features but just on stock kernel, I'm getting great battery life out of it! I'm at 41% now with 39hrs standby and 5hrs SOT with less than 5hrs on wifi!
Stock kernel has input boost clocked at 1.7Ghz and stock interactive 1.2Ghz (hispeed_freq) with minimum frequency at 300Mhz and maximum frequency at 2.5Ghz. I did not tweak any kernel related things.
