Hi guys,
this is the 1st release of the platypus (custom) kernel for CM7 (CyanogenMod 7)
You asked for it - you get it !
I'm looking for a thread maintainer here at the vibrant development subsection
anyone wanting to run a thread for the platypus kernel ?
many thanks in advance !
Now to the fun part:

Changelog:
[additions since 04/13/2011] (release name: Antlion; Stable )
* working external SD card access & usb tethering
* working auto-rotation and sensors (check it's on; if not working: 1st boot: power button press 10+ seconds -> forced reboot/hard reset)
* CONFIG_HZ @250 USER_HZ @150 (like "rocketeer")
* (almost) feature-complete (like "rocketeer")
* added ported new bcm4329 (WIFI) drivers from intersectRaven's 2.6.37.6 kernel - kudos to him (supposedly less battery consumption)
* better reception quality (less noise) with new WIFI drivers

Installation steps:
* make sure you have auto-rotation enabled with previous kernel
* boot into CWM Recovery
* apply kernel package (zip-file)
* Wipe /cache & Dalvik Cache
* "reboot system"
* give it some time to boot
* check if auto-rotation works - (is it enabled ?) - if not press power button 10+ seconds (ignore power menu popping up)
* after the next boot it should work

Troubleshooting:
Q: black screen during 1st boot - shortly pressing power button doesn't fix it - only soft keys activated (perhaps screen activated but no output visible - black)
A: keep power button + home + vol up pressed until it reboots; it shows samsung galaxy s logo - hold it for some seconds shortly before the cyanogenmod splash appears (timing !) [same like getting into Recovery]
Wipe /cache & Dalvik Cache again & "reboot system" - now it should work
Q: auto-rotation not working !
A: check that it's enabled in settings or the notification power widget
it it still does not work tilt the phone and wait for some seconds - still not working
press power button 10+ seconds until it reboots (ignore appearing power menu) - that forces the phone to reset state and "hard"-reboot - now it should work

thanks !
some info from the main thread (at i9000 development subsection):
DISCLAIMER: the kernel (binary) and driver modules are provided as is. If problems occcur they most probably are from upstream and can be fixed with the newest version. Since I'm doing this in my free spare time as a hobby (quenching my thirst for tweaks & performance) updates will occur irregularly as time permits and I see fit (most probably when new features & bugfixes arrive). YOU are responsible for the actions that you take (such as over- or underclocking), etc. You agree that I can not be held liable for any potential damage that arises from your actions in combination with or the usage of this kernel and other related parts.
Kudos:
* Google & the whole Android crew
* Linus Torvalds & the kernel hackers for upstream Linux
* cyanogen & all the devs out there hacking on this
* Supercurio for enriching our media experience of this smartphone

3.2. Using CPUfreq Governors (Red Hat Documentation - hope they don't mind for the load)
cpufreq_performance
The Performance governor forces the CPU to use the highest possible clock frequency. This frequency will be statically set, and will not change. As such, this particular governor offers no power saving benefit. It is only suitable for hours of heavy workload, and even then only during times wherein the CPU is rarely (or never) idle.
cpufreq_powersave
By contrast, the Powersave governor forces the CPU to use the lowest possible clock frequency. This frequency will be statically set, and will not change. As such, this particular governor offers maximum power savings, but at the cost of the lowest CPU performance.
The term "powersave" can sometimes be deceiving, though, since (in principle) a slow CPU on full load consumes more power than a fast CPU that is not loaded. As such, while it may be advisable to set the CPU to use the Powersave governor during times of expected low activity, any unexpected high loads during that time can cause the system to actually consume more power.
The Powersave governor is, in simple terms, more of a "speed limiter" for the CPU than a "power saver". It is most useful in systems and environments where overheating can be a problem.
cpufreq_ondemand
The Ondemand governor is a dynamic governor that allows the CPU to achieve maximum clock frequency when system load is high, and also minimum clock frequency when the system is idle. While this allows the system to adjust power consumption accordingly with respect to system load, it does so at the expense of latency between frequency switching. As such, latency can offset any performance/power saving benefits offered by the Ondemand governor if the system switches between idle and heavy workloads too often.
For most systems, the Ondemand governor can provide the best compromise between heat emission, power consumption, performance, and manageability. When the system is only busy at specific times of the day, the Ondemand governor will automatically switch between maximum and minimum frequency depending on the load without any further intervention.
cpufreq_userspace
The Userspace governor allows userspace programs (or any process running as root) to set the frequency. This governor is normally used in conjunction with the cpuspeed daemon. Of all the governors, Userspace is the most customizable; and depending on how it is configured, it can offer the best balance between performance and consumption for your system.
cpufreq_conservative
Like the Ondemand governor, the Conservative governor also adjusts the clock frequency according to usage (like the Ondemand governor). However, while the Ondemand governor does so in a more aggressive manner (that is from maximum to minimum and back), the Conservative governor switches between frequencies more gradually.
This means that the Conservative governor will adjust to a clock frequency that it deems fitting for the load, rather than simply choosing between maximum and minimum. While this can possibly provide significant savings in power consumption, it does so at an ever greater latency than the Ondemand governor.

thanks ill give it a try
Thanks for the kernel. Much appreciated.
Which version are you guys using? Conservative seems a little choppy to me, anyone else experience it with conservative?

Just tried the ondemand version and it feels choppy like conservative.

Choppiness at First..
Goes away after awhile (I am using Conservative)
Also rebooted twice.
I think it just needs time to settle in. Seems to be running smooth now..
I'm gonna try this out in a bit. Nothing to lose I suppose.
I'm looking for a thread maintainer here at the vibrant development subsection
anyone wanting to run a thread for the platypus kernel ?
many thanks in advance !
I can maintain it, I maintain the other CM7 kernel thread, shouldn't be too tough.
I'll test the releases before and make things nice and tidy, etc. (If you'd like.)
Let me know.
Thanks for the kernel, by the way.
Great kernel has IP tables but i can get it to rotate for the life of me....also feeling lag but quadrant and smartbench say it's running better....rebooting.....
EDIT: Rebooted many times....tried holding power for more then 10 sec but nothing no rotate or light sensor
I would like to maintain also, I'm willing to test (I have 2 vibrants) maybe me and someone could work together on ones behalf.

I think I found a temp fix for no auto-rotation. Turn your phone off, than as you turn your phone on, keep your phone standing in landscape on a table or in your hands. It should now auto-rotate. Hoped I helped in anyway.
I don't know if its the kernel or the nightly update, but my camera won't start and FC.

Its the update, just checked

So far no issues. Auto rotate working as it should. Games seem to play the same as previous Kernel. Will give it a full charge tonight and get a better idea of battery life in the next couple of days.
when you say:
* apply update.zip
newbies may press something different...
you should probably tell them to install the .zip from Sd card option or something...
trying it out now, its rebooting.
hope it works, and how would i know if its enabled or know that i'm using this kernel?
(im on MIUI)
pretty sure the kernel mind-****ed my phone.
i was at about 31% battery.
Flashed kernel, 16%
rebooted, 12%
lol.
Works with MIUI also. May want to add reboot after flashing. I actually had to reboot twice before it settled in! Great work!

1st Minor Hiccup - Theme Change
Running Vibrant - CM7 + MIUI:
Changing Themes gave me a constant reboot.
Fortunately a battery pull did the trick and the new theme came up.
(EDIT) Might be a one-time adjustment .. I put another theme on and rebooted fine. So changed back to the other theme to see if there was an issue with the theme itself and that came up fine as well.. just one of those one-time quirks I guess..
I've written many new kernel threads, so I'll just try to make this one simple, easy and light to read.
So, let me give you a little background on me: most of you don't know me as I only bought this device few days ago, but I'm a kernel dev for two other phones, the LG P500 and the Ideos X5. Worked on both .32 and .35 trees and my works became very popular, which can be seen by following the links in my signature - specially in the P500 community.
There are plenty of kernels to choose already, so why release another one? Simply because what I have to offer none of the other kernels had. What do I bring? Performance. How do I achieve that? Check the changelog and you'll understand...but not yet, lemme finish!
I have to say this: this kernel is based on KalimochoAz sources, so every changes up to his last pushed sources it's his job, so credits to him, I take no credit from his job.
I didn't start this kernel project for recognition or anything like that, I just want to share what I did for myself, maybe someone will find it useful
So let's get started, below you'll see what I changed on top of KalimochoAz source:
8th December
* Deep_idle code deleted, and re-added. Everything is exactly as Ezekeel has in his kernel, this might, or might not help with the data loss and whatever. If you still have problems please consider disabling deep_idle and see if it helps
* Deep_idle is off by default - changeable with NStools
* Calibrate.c reverted back to the .35 implementation
* Updated CRC32 library to the latest implementation directly from its creator
* Fsync disabling code deleted and re-implemented with a different implementation
4th December
Too many changes, so I'll be just brief and simple:
* CFS autogroup tweaks
* CFS optimizations
* Readahead values automatically calculated by the kernel for the optimal performance
* Several optimizations to lib files
* Added dm-cache (http://visa.cs.fiu.edu/ming/dmcache/)
* More stability
* Much more...
25 November
* Fsyncs disabled - more IO speed, more battery (less IO operations)
* Compiled with the optimized Mjolnir toolchain
* Added 1,2ghz step
* New default colors for the SAMOLED screens
* Cgroup: speed up access to cgroupfs mounted entries in /proc/mounts
* One or two more minor tweaks and optimizations
23 November
* No more BFS code and BFS builds. I want to make sure this is stable enough. If you want BFS compile it yourself. I hope this fixes the data/gsm drops
* Minfree settings unlocked forever
* Readahead value bumped to 1024
* BLN/touchwake fix
17 November
* Patched up to the latest deep_idle version from Ezekeel
* SAMOLED colors tweaked, should be a lot better now
* Few stability updates and reverts to ensure everything is up and running without issues
* Interactive governor added again
* Interactive patched up with around 10/15 patches
* Minor tweaks and optimizations
13 November
* Based on the latest testing builds, which includes:
* Some defconfig options change for a more leaner kernel
* Delete two cflags to ensure maximum Hummingbird performance
* Internal sdcard remount bug fixed
* Minfree settings unlocked by users demand
* Deep_idle implementation changed (it's the same that I used in the last testing version)
* Added latest deep_idle patch that when the phone vibrates it uses the TOP=ON idle state
* Removed obsolete screen dimmer
* Updated BLN to latest v9
* Lazy governor changes based on morfics lazy changes
* Remove Big Kernel Lock tracing
* Some stability patches from the kernel mainline
8 November
* PMEM disabled as herring doesn't use it - this way we recover 12,5mb ram
* Ext4 mounted with special flags directly on the kernel source - more performance without needing init.d scripts
* Writeback settings now working correctly and are not overwritten by the ramdisk
* Minfree settings are now correctly set and are not overwritten by the ramdisk
6 November
* Latest deep_idle bugfix from Ezekeel
* Added Ezekeel's custom_voltage mod. For more info about it visit the respective thread. Yes it's compatible with SetCPU, maybe with Proton too, I didn't test it
* Added back BLD, touch wake and screen dimmer
* Improved CRC32 algorithm - it's used for many kernel functions
* CFS version: Cgroups: introduce timer slack subsystem - Provides a way of tasks grouping by timer slack value. This functionality is useful in mobile devices where certain background apps are attached to a cgroup and minimum wakeups are desired
3 November
* Latest deep idle bugfix from Ezekeel
* Offering two separated downloads, one CFS and another BFS. Don't ask me which one is better, try it and see, I'll be really mad if I get questions like that
* Idle_stats show 0 in every field - don't worry about that, it happens because of my cpu_idle 3.1 backport, but I assure you deep idle is working. Again I'm not answering questions like "WHY IS IDLE STATS 0?!?!? HALP PLZ".
* 'screenoff_maxfreq' is disabled by default. If you want that behavior write this in the terminal: echo 1 > /sys/devices/system/cpu/cpu0/cpufreq/lazy/screenoff_maxfreq
2 November
* Newest deep idle bugfix from Ezekeel
* Reverted back to CFS because stock users had mounting problems with the sdcard and some users had data/wifi drops and I don't want that
1 November
* First and entirely BFS kernel with the newest 0.413 version
* Optimized the tunable BFS parameters for extra interactivity and smoothness
* More debugging disabled - I'm pretty sure 99% of the debugging flags are now disabled
* All the latest bugfixes and implementations from Ezekeel, including live_oc up to 150, lazy maxfrequency_screenoff enabled by default and all the other small fixes to ensure maximum stability
* Small changes to the lowmemorykiller
* Added optimized RWSEM algorithm
* Added some minor improvements and tweaks
* Sorry devs that wanted logcat, it's still a module because I suspect I'll have to update this build again with some extra fixes from Ezekeel in a very near future thus not making much sense to release two kernels now, one with logcat on and other with it off because that takes time to compile. If you desperatly need logcat go to my .config and change CONFIG_ANDROID_LOGGER=m to CONFIG_ANDROID_LOGGER=y and recompile it
27 October
* Latest deep idle and live oc bugfix from Ezekeel - should fix that extra battery drain reported by some users
* Changed lowmemorykiller.c - minfree settings already incorporated in the file. Settings kanged from morfic's tweak file, thanks
* Add cleancache - driver to cache clean pages
* Fixed ext4 disk write performance regression
* Small power management fix to back off suspend if repeated attempts fail - avoid continually trying to suspend in situations in which a driver is repeatedly rejecting suspend or a pending wakeup interrupt is not handled, burning CPU in the continuous suspend attempts
* Lib file added for the users where BLN didn't work
* Logcat module added inside /system/modules. If you want to use logcat just load the module with insmod
24 October
* BLX added again by default and patched up to the latest fix from Ezekeel
* Deep idle patched up to the latest fix from Ezekeel
* Live OC added and patched up to the latest fix from Ezekeel. To overclock you need to do this in the terminal or in an init.d file: echo 110 > /sys/class/misc/liveoc/oc_value. The 110 value means that both cpu frequency and bus frequency will be increased by 10%. You can increase this value as much as you want, as long as you increase the voltages otherwise the device won't handle it, but that's obvious.
* Changed dirty_writeback values from morfic to increase smoothness
* Overclock frequencies removed. The device is fast enough with 1000,800,400,200 and 100 frequencies. If you want to overclock use Live OC, it's enough to make it fly
* Conservative governor tweaked - smooth as butter
* Removed a ton of debugging ****
* Deadline I/O scheduler made default - after much testing it seems to produce the best and more regular results
* Swappiness disabled
* For more information visit my github, this are the most important changes
21 October
* Latest Deep idle bugfix from Ezekeel
* sched: disable GENTLE_FAIR_SLEEPERS
* Remove few obsolete governors
* BLN fix for MIUI users - now it should be propely set and full working
* Just 3 more tweaks:
PM QoS: Correct pr_debug() misuse and improve parameter checks
mmc: core: put eMMC in sleep (cmd5) mode before suspend
vmscan: prevent background aging of anon page in no swap system
19 October
* UV **** is fixed, SetCPU and Proton should work fine now
* Config_HZ increased to 1000 by request of an user
* Small tweak to VR
* Compiled with special Cflags from netarchy
* Calibration tweaks for touchscreen from netarchy
18 October
* Update cpu freq. to allow UV interface - you can modify the voltages on the fly going to /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table with an easy layout
* Auto BLN added again - it works now out of the box without the need of an extra app
* Add Lazy governor by Ezekeel
* config edited again, removed alot of **** options that are not needed at all - this way the kernel is even leaner
* cpu_idle backport from 3.1 - maybe helps with the BSOD problem
* Tweaked VR scheduler to work better for flash devices like our Nexus
* Ext4 tweaks
* A lot of USB tweaked code
* More fs tweaks to decreast CPU usage on unecessary ****
* More TCP/IP tweaks
* vfs_cache_pressure -> 25
* dirty_background_ratio -> 60
* dirty_ratio -> 90
* vm_swappiness -> 30
* Sysfs interface for deep_idle created by Ezekeel was added. If you want to disable deep_idle run this command: echo 0 > /sys/class/misc/deepidle/enabled
* Screen refresh rate increased to 65hz, everything should be even smoother (thanks morfic)
* If you want more detailed information about all the tweaks added you can visit my github
----------
* No more debugging **** in the kernel. No logcat, no dmesg, no debug_kernel etc etc, this **** is clean on that logging stuff that only consume CPU cycles in the background
* CFS scheduler tweaked with custom settings
* dirty_writeback value increased from 5*100 to 15*100, reducing unnecessary I/O activity, thus releasing a few CPU cycles
* Deep Idle mod by Ezekeel (latest version)
* Few patches to lowmemorykiller.c hopefully to optimize memory usage
* Add VR I/O scheduler and made default. A lot of performance gain comes from this one.
* Also enabled BFQ scheduler to be an option with no-frills
* init/calibrate.c port from 2.6.39. Better loops per jiffy calculations
* vfs_cache_pressure 100->50
* Add Stochastic Fair Blue (SFB) network scheduler and make it default. This is a network packet scheduler, should make internet usage a lot smoother
* Changed TCP_congestion scheduler to TCP_Veno. TCP Veno module is a new congestion control module to improve TCP performance over wireless networks. The key innovation in TCP Veno is the enhancement of TCP Reno/Sack congestion control algorithm by using the estimated state of a connection based on TCP Vegas. This scheme significantly reduces "blind" reduction of TCP window regardless of the cause of packet loss.
* Tiny RCU is the default RCU engine. More explanation on this RCU here http://lwn.net/Articles/323929/
* Kernel compiled with -O2, meaning the code is more optimized instead of being compiled for size
* WiFi = PM_FAST in standby
* Optimized the config options for CFS Autogroup in the .config file, it should be perfect now
* Again more and more debugging disabled
* Obviously some minor changes and tweaking, but that can all be seen in my github below

When I bought my Nexus I thought "No, I'm not compiling any kernels for it, no more flashing endlessly in a loop every night."... I guess I wasn't successful
Jokes aside, better share it to the community instead of being selfish and use it only myself - I'm kinda happy with the result and maybe I can make someone happy too, that's my goal!
Is this just for the Nexus S or will it run on the 4G also?

Hmmm... good question. I used CM's kernel sources, like I mention in the op. Considering that probably S and 4G versions of CM7 share the same kernel, I'm mostly certain that it will work. Just do a backup of your installation and try it out, I'm kinda curious as well.

Sadly I'm having all the stability issues I had with the CM7 kernel only now some of my news apps cause a reboot. :-(
After a very short test: fast as morfics kernel (Quadrant 4200 by 1,2GHz) and internet is really smooth, special on 3G.
Performance is pretty good, battery life isn't terrible. I get better with morfic's TEUV, but that's kind of expected. Overall it's a nice kernel, I'll stick it out a few days and give it a true test.
So far, quick, stable, battery charges quicker than normal, and charges to 100%. Ran some quadrant standards and it seemed to be on par with other performance kernels. I am running this with Oxygen 2.3.1. Looking forward to running this through the day tomorrow. Good stuff.

Welcome to Nexus S. Haha.
I flash your kernel and everything was good. No FC, no bootloop, everything went fine
new kernel~!!
must flash~
But heading to mountains in an hour... will definitely flash when i come back.
i want stable phone before heading into the mountains... ><

You know you want to put it on the sdcard, and flash, just real quick, then flashing back to your stable kernel just before taking off.
You know it's calling you, you know you can't wait, you live in the now, you are a crackflasher.
missing BLN.
Just flashed it and getting a bsod when waking the phone as I do with other kernels with deep idle.. I don't seem to get it with morfic's test builds though..
Other than that it is very fast and the internet seems a lot smoother...

When I bought my Nexus I thought "No, I'm not compiling any kernels for it, no more flashing endlessly in a loop every night."... I guess I wasn't successful
Jokes aside, better share it to the community instead of being selfish and use it only myself - I'm kinda happy with the result and maybe I can make someone happy too, that's my goal!

- fix: p54spi: Add missing spin_lock_init
- fix: Generate correct i2c address sequence for 10-bit target
- oprofile: Fix crash when unloading module (nmi timer mode)
- Huge source cleanup
- cpu: make a kconfig menu that predefine AVP Overclock Freq, 3D Overclock Freq, DDR2 SDRAM Freq im trying to avoid static definitions. Everything what is possible is calculated dynamically from this values. This give as a much better compatibility.
- cpu: added support for cpu freq statistic polling
- cpu: add minmax governor software emulation
- cpu: added support for cpu screen off max freq (merged from SetiroN source)
- version: kernel version changed to 2.6.32.51
- cpu: added support for minimum number of ticks between polling interval for governors
- cpu: added support for sampling rate multiplier for governors
- block: fix default readahead size for small devices
- added fix for the function setup_vpif_input_channel_mode() that used the VSCLKDIS register instead of VIDCLKCTL. This meant that when in HD mode videoport channel 0 used a different clock from channel 1.
- crypto: added support for LZO compression/decompression
- power: added support battery driver for batteries implemented using NVIDIA Tegra ODM kit PMU adaptation interface
- added support: gpu can use overlapping system memory with some restriction, now is possible to build a special ramhack with increased total memory while the cpu is still can use maximum 128MB ram, if needed free up the system memory (refer to the carveout killer)
- added support PL310 errata: no automatic Store Buffer drain. On revisions of the PL310 prior to r3p2, the Store Buffer does not automatically drain. This can cause normal, non-cacheable writes to be retained when the memory system is idle, leading to suboptimal I/O performance for drivers using coherent DMA. This option adds a write barrier to the cpu_idle loop so that, on systems with an outer cache, the store buffer is drained explicitly.
- asm: Split trivial #if defined(__KERNEL__) && X conditionals to make automated
disintegration easier.
- power: redefine/optimize freq's and voltages based on the LG reference table (for better compatibility)
- fix: improve charging bsod fix
- every vorkkernel patch is already included
- included some usefull patch from the swiftextreme kernel (almost nothing can be usefull its sad that fajarep leave this community, but thanks for him his great work!)
- blockio: added SIO scheduler, updated BFQ scheduler
- zram: improved zram staging driver, fix sparse warnings, default zram devices increased to two (one for the swapped space, the other is for free use). default size, num devices depends on a config option.
- cifs: fix cifs stable patch cifs-fix-oplock-break-handling-try
- input device: add multitouch input library, improve toch screen responsiveness
- input: multitouch: Add hovering distance axis. The device now capable of contact hovering can use a special flag to indicate the distance between the contact and the surface.
- added support for predefined carveout_size (for the ramhack) (credits to SetiroN for the idea!)
- sched: Avoid unnecessary overflow in sched_clock
- memory: work-around (a.k.a. hack) to prevent pages with __GFP_COMP being passed to split_page() which cannot handle them.
- wm8994 audio driver: possible fix left and right speaker channel inbalance. boost left channel volume what is lower than the right channel
- mmc: core: eMMC in Sleep mode before suspend
- memory: Reclaim nvmap carveout by killing processes. Allow the system to reclaim carveout space by killing processes. This will kill the largest consumers of lowest priority first.

[CM7/MIUI Kernel][KANG][JUN14]CM7-ETaNa v3.0.34
Kernel 3.0.34 "stable" branch
Based on wkpark sources, cherry picked updates from the official linux kernel github source, Code Aurora and Linaro sources
I thank every developer who made their patches available to the public!
I wanna say thank you the following persons!
Spica1234 for the on the fly (aka OTF) pack. He is a great and dedicated developer, helping a lof about the OTF integration. Thank You bro!
Culblueswan for the Etana config editor application. He is developing this app so fast, made it the config change userfriendly. Thank You!
Important!
The first boot may take while, its possible that after the second LG logo the screen will be black, DONT!! pull out the battery, just wait a few second, the bootanimation will be show soon. The second boot will be much more faster
Linux version 2.6.32.y is discontinued, only emergency bugfix will be available in the future
Touch CWM is incompatible with this kernel!! Use the normal CWM version! Its possible that the touch CWM cause the filesystem corruption and the r/w bug.
Latest SetCPU have a bug even with the 2.6.32 kernel sometimes (and the stock cm7 too), that the second core will be always active! Use the 2.2.4 version, its working fine.
Antutu CPU master 100% compatible with the kernel 3.0.y (have many profile and cpu1 deactivation is working fine)
Recommended using Antutu Battery Saver app
3G eat the battery fast, its a weak point of the O2X. Use the Toggle2G app for switch back to 2G if the screen is off or the network is not used. This will help to save a LOT battery life

Spica OTF tweaks realtime parameters can be adjusted via the official HP kernel tweaker app (found on the market). The boot time parameters can be adjusted from the Etana config editor app (included in the kernel installer).
Spica OTF pack further information can be found in this forum: http://forum.xda-developers.com/showthread.php?t=1295486
You can find any information what you need in there.
Installer configuration file need to be place in the sdcard root. You can set what you need and the future version respect that file, so dont need to change anymore. Example: you can exclude that install the custom font.
Note: The kernel installer just update your tweakaio config file with the cpu uv parameters, not overwrite, so if you have custom values you not loose them.
The New parameter file location is: /data/tweakaio/tweakaio.conf
Log files in: /data/tweakaio/tweakaio.log
The installer script respect the parameter file in the future, so if you have some custom settings you will not loose this in a kernel update.
Parameter file is optimized for the phone screen, it can editable with any text editor app or with the Etana kernel tweaker app.
Kernel Features
Balanced AVP OC freq
Balanced 3D OC Freq
Balanced DDR OC Freq
Balanced Second Core Management (lag free)
Default CPU freq is 1015Mhz
Max CPU speed is 1216Mhz/1408Mhz depend on OC profile
Optional Compcache (disabled by default) (you can enable that by editing the /system/etc/init.d/90tweakaio file and change COMPCACHE="off" to COMPCACHE="on"
System logger is leave enabled by default (you can disable that by editing the /system/etc/init.d/90tweakaio file and change LOGGER="on" to LOGGER="off"

Recommended CPU profiles for optimal performance
No1: In call: 216-456 or 324-456(*)
No2: Screen off: 216-324 or 324-324(*)
No3: Charging: 216-1408 or 324-1408(*)
No4: Battery <20%: 216-816 or 324-816(*)
Note: (*) Use this if you're having a problematic phone (which doesn't like UV and has a lot of BSODs). The stock kernel doesn't use the 216Mhz setting, some hardware may not support this(!), so that's why I recommend to use 324Mhz as the minimum value if you have problems with 216Mhz.

awesome nice work mate goodluck and keep the good work comming!
looking forward
Finally you made your own thread
It started to become a little confusing over in the old thread.
I really love your hybrid version of IronKernel and hope that this kernel will be awesome too. I'm looking forward to it
Sent from my LG-Stone from the Prehistory...
Nahh... Just kidding!
CM 7.2 Koboltzz KANG

good luck on your new built.
I'll help testing on my free time.
by the way how can i modify the name of my own thread? i see that other users can do that.

Good luck !! I can't wait
i was update the first post some news
Waiting for noram hack cause want to 100% working my phone
amazing new features
nice kernel for o2x will wait to try it
BTW It will be compatible with CM 7.1 stable?

Most probably yes - but I would advise you update to latest KANG since CM7.1 stable is rather old now...
Yeah, but for me is very fast, and solid stable (any BSOD or freeze after few days using) so I don't see any reason to upgrade OS to experimental build. If I aint right explain me
im finish the cherry picking for now, all of the important patch is merged.
im start to write a CWM update script with some optimization. i dont want to release this kernel with only a simple kernel reflash
the good news, the hard work is done
STOP! This kernel supports ONLY CM10.1.x, AOKP-4.2.2, PA-4.2.2 ROMs.
It won't work on Samsung Jellybean/ICS, AOSP ICS, CM9 or CM10.
Carbon ROM may be incompatible with NX-Kernel.
✯ ✯ ✯ ✯ ✯ NX - KERNEL ✯ ✯ ✯ ✯ ✯
... because we deserve more ...
Description:
Welcome folks! NX-Kernel is highly advanced kernel for pure android ROMs. It is under continuous development with new features along with integration of new linux kernel.
NX-Kernel auto-installs NXTweaks app. This app based on STweaks by GokhanMoral. This app is core of this kernel. It will help you to fine-tune and get total-control over your kernel.
Touch-sensitivity, GPU, CPU, Kernel, mDNIe, Charging currents, etc already tweaked and controllable by NXTweaks.
Dynamic Tweaks enabled by CortexBrain will help you to save power and increase performance at the same time! It gives dynamic tweaks based on screen on or off.
Use it to experience it! You can read more features below.
One more thing, I would like everyone to know - Only Kernel is not responsible for your device.
Device configuration, ROM, installed app, usage plays important role!

How to obtain optimum battery life?
▷ If you are comparing/complaining battery life on NX, CM, touchwiz kernels, NX is not for you, stay with CM/touchwiz.
▷ NX Kernel is more performance driven and little less battery saver compared to CM Kernel.
▷ This is because we use 16 dynamic frequency steps, high performance governor, and advance features.
▷ In case you overclock CPU or even GPU, you are tend to have less battery life. So don't overclock if you wish battery over performance.
▷ Do not undervolt too much, it starves your device and may have adverse effects like SOD/freeze/soft reboot.
▷ There is a app named 'Battery Widget Reborn', use it and enable Night Mode Power save.
▷ One more app 'Fast Dormancy Toggle for I9300', use it if your network doesn't provide dormancy. Google for more info.
▷ Don't keep monitoring battery every now and then. Treat it good.
▷ Have full battery-charge cycles 2-3 times in a week which means when battery drains below 20%, charge it to 100% without interruption.
▷ Sign out google talk / hangout if you don't use, it drains power.
▷ Wakelocks is another enemy if they come unnecessarily from installed apps. You can monitor with very good app named 'Better Battery Stats', it's paid app.
▷ Use Performance/Extreme Performance profile from NXTweaks only when required, restore default whenever possible.
▷ It is highly recommended to turn off AUTO SYNC option day time and use it only when charging.
▷ Even your touch-screen drains power when screen on. Never use full brightness. Use auto-brightness or low brightness.
If you follow these advice atleast for a week, you will have optimum battery life!
In case you have SOD (Sleep of death) or SOFT Reboot, please check following:
✔ Minimum Frequency should not be less than 200 MHz
✔ You are using stock settings for voltages and haven't undervolted
✔ Default Governor is stable one, recommended to use for good stability
✔ You haven't installed or have activated any apps or scripts which interrupt settings of NXTweaks
✔ Similarly, do not use apps that implements profiles like 'screen off' , 'on call', etc
WiFi Issues? Follow the below steps:
▷ Open WiFi Advanced Options. In region, select any region and then select US. This may not be available on all ROMs.
▷ Open NXTweaks, under Tweaks Tab, tap on "Clear WiFi Lease" button.
▷ Under Charging Currents Tab, tap on "Reset Fuel Gauge"
▷ Reboot in recovery, Fix permissions.
If you still face issue, clean install good compatible AOSP ROM + Gapps, (optionally flash NXKernel), follow above steps.
If issue persists, you may need to get hardware checked.
Topic explaining all basic Governors & I/O Schedulers: Click Here
Default Governor:
Hyper - The Hyper (formerly known as kenobi) is an aggressive smart and smooth, optimized for SMDK4210 board getweakt and, based on the Ondemand, which was getweakt of Arighi and was equipped with several features of Ondemandx suspend imoseyon. (Added by sysfs, the settings suspend_freq and suspend Imoseyon's code) is the behavior of the hyper Ondemand if he is in action, very similar. He also has the Arighi's fast_start deep_sleep and detection features.
Default IO Scheduler:
ROW - ROW is Read Over Right. As name suggests it services more READ requests than WRITE taking care that WRITE requests don't starve. It is most suitable because Android handhelds unlike desktop hardly uses multi-threading and a user seeks more of responsiveness than giving more input.
My Recommendations:
Recommended Governors: HYPER > NeoX > SmartAssv2 > LulzActiveq > Nightmare > Intellidemand > Others
Recommended Schedulers: ROW > ZEN > BFQ > CFQ > SIO > NOOP > Other

F.A.Q.:
Q. I am getting FC / Performance control not working. What is the solution ?
A. Reboot in recovery. Wipe cache and dalvik cache.
Q. I am getting sleep of death. What do I check ?
A. Adjust minimum frequency to 200 MHz and not lower.
Q. Which is best governor and IO Scheduler?
A. All of us have different choices. There is no thing like best governor or IO Scheduler.
You need to set your personal favorite. I have posted my recommendation in above post.
Q. It takes long time to boot. What is wrong ?
A. Nothing is wrong. Let NX optimize your apps and database.
Q. How to insert a module that's available in /system/lib/modules?
A. Safe to be root. In terminal or adb
su
insmod /lib/modules/<module_name.ko>
You can request your required module, if you want.
Q. How to know which modules are pre-loaded by kernel?
A. Terminal or adb:
lsmod
Q. I want to help dev debug an issue providing a kmsg. How to?
A. After the problem (random reboot/freeze/lockup), do not pull out battery to recover. Just long press power button so that device can reboot. Then connect device to PC, (provided you have setup adb), type
adb pull /proc/last_kmsg
Save the file as .txt and post in the thread along with description of the problem and possible way to reproduce it.
If you can't use adb from pc, just copy last_kmsg file from /proc directory to internal sd, copy it to your PC and post in the thread.

Re: [KERNEL][3.0.69][4.2.2 - CM/PA/AOKP] DH-Kernel v1 [16/03]
Nice one @Neo
the release of any new kernel is a time for rejoicing for any xda community. hope this one also covers a long journey :good:
Running the kernel on (unofficial) Mad Cow Rom. First impression: Good!
Great to have a AOSP-Kernel with Philz-Recovery! :good:
Small issue: If you select Misc nandroid settings in Backup and Restore, it's not working. Backup and Restore Menue appears again.

That's because PhilZ recovery is not fully open source.
We will switch to better one.

Warning:
It's your device. It's your responsibility for what you flash. Do not blame us.
DO NOT flash over forbidden kernel as that kernel has incompatible/unstable/non-tested init.d scripts.
Do not discuss forbidden kernels over here. Hail open-source!

Thanks Neo.
I know it's uncommon to read OP, but I like your humor: The combination of warning two and three. somehow paradox. why are warning about something which you dislike to discuss. Sorry, might be OT.

That means you have been fiddling around with it. . Anyway need to stop some off topic.
Please keep it updated. We need some Fire from this Dragon.
flashed/running it now,smooth no probs:good:..thnx
Excellent Kernel
I have been running the kernel for a little over an hour now and it is excellent, super smooth and responsive.
I like the name DragonHeart.......... makes the kernel sound very powerful and dependable.:good:
Overclocked too, awesome.:good:
The only changes I have made are:
100MHZ and 200MHZ voltages to 900 mV
Governor to SmartassV2
I wiped Dalvik and Cache before flashing the kernel.
@Neobuddy - Do you have those wipes built into the install script???
I.E. Do I need to wipe dalvik and cache before install???
Thanks for the excellent kernel.
Re: [KERNEL][3.0.69][4.2.2 - CM/PA/AOKP] DH-Kernel v1 [16/03]
Flashed. First 10 minute impression is.. Fantastic! Smooth! Didnt changed any value. Just the governor to smartassv2 and scheduler to still bfq which i the default. Will come back after couple of days and see how it goes. Thanks so much!

That should be a bug in performance control app. I noticed it when I used aokp rom based, so I searched on net and I found that it should be an app bug. Just use any other app, like voltage control

F.A.Q. --
1. My WiFi doesn't works after flashing this kernel.
Extract wlan.ko from the .zip of kernel (located under system/lib/modules/) and place it in root/system/lib/modules/ overwriting the one already present there. Then, set the permission of the file to rw-r-r and reboot the phone. Use ES File Manager with Root Permission to do this.
OR
Place the .zip of the kernel in Internal Storage and then re-flash the kernel.
OR
Check free space in /system partition. Atleast, 25 MB of free space should be there in /system partition as less space prevents the wlan.ko file to get copied successfully.
OR
Flash the latest version of SuperSU.
OR
Change the ROM.
2. Which Android Versions does this Kernel supports?
AzurE Kernel supports Marshmallow and Nougat ROMs. However, not every Kernel Version supports every Android Version. Check Changelog of the specific Kernel Version before flashing it.
3. Does VoLTE works on this Kernel?
Yes, if the ROM supports VoLTE, then this Kernel will also support VoLTE. However, if the ROM doesn't supports VoLTE, then this Kernel won't too.
4. How long are you planning to continue development of AzurE Kernel for Yu-Devices?
As long as I have my Yu Yureka PLUS with me, I'll keep the development active.
5. I have a feature-request!
Well, feature-requests are accepted only when I find the said feature to be having some practical use or substantial positive effect. Whether I include the feature or not, is purely my decision.
6. Why don't you answer my queries? I have asked 10 times already!
It takes much time in developing and testing a Kernel. So, it is difficult for me to keep track of every query too. However, if your query is a genuine one (i.e., not a duplicate question or a question, the answer of which isn't present in the First Post or the Changelogs), then I'll surely answer it.
7. Kernel Adiutor shows blank space in Governor and Frequency Panel of CPU TAB.
When Core 0 gets disabled (due to Core Control or State Helper HotPlug), Adiutor fails to get Frequency and Governor information and hence shows 0MHz in Frequency Panel and Blank Space in Governor Panel. This is normal. In this case, if you need to change Governor or Frequency, then you need to disable Core Control or State Helper HotPlug as the case may be. After this, force close Adiutor and then re-open it. This will make Adiutor get CPU information again. Also, if you don't want to face this situation again, then disable HotPlug Boost Toggle (this will make the kernel to not disable Core 0 and hence, such situation won't arise).
8. The HotPlugs aren't working! After sometime, all the cores come online.
After manually changing the CPU Governor or Frequency, all the Cores will come online even if any HotPlug is enabled. So, you just need to re-enable any HotPlugs you were using in order to disable the Cores again.
9. My whole big Cluster is offline! I can't enable it anyway!
Well, my kernel uses Core Control v2.0 (built by me) and hence, it has the ability to disable the whole big Cluster (including Core 0) if temperature rises above 55 C. When the temperature comes below 55 C, the big Cluster is brought back online again. This is normal and is done to reduce heat. Moreover, if you don't want Core 0 to get disabled, then you can Disable the HotPlug Boost Toggle (available under CPU TAB).
10. The CPU Frequencies are locked. I can't change them. This is a very serious BUG.
I wouldn't call it an issue or a BUG. It is a feature. My kernel uses a Custom Thermal Driver. It reduces the Frequencies to keep the temperature of the Kernel within safe limits. Hence, sometimes, when the temperature is above a certain degree, the Thermal Driver locks the Maximum Frequency so as to lower the temperature of the SoC. However, in my kernel, everything is user-configurable. So, if you want more performance and can bear some heat, then you are free to set the Thermal Settings according to your preference. These settings are available under the Thermal TAB of the Modded version of Adiutor only.
11. I don't have a 1.5A Charger. Should I use Quick Charge or not?
Let me clear this in a simple yet detailed way.
To use ThunderCharge's 1250 mA value, one needs a Charger capable of supplying 1.25A. So, if you're using a 1A Charger and you have set 1250 mA in ThunderCharge, then it won't work. The Charging will only occur at a speed of 1000 mA which your Charger supports.
Similarly, Quick Charge requires a 1.5A Charger for it to work fully. However, this doesn't means that using a 1A Charger with Quick Charge will affect Charging Speed negatively. So, if you're using a 1A Charger, then Quick Charge will draw only 1000 mA.
As for the Dynamic Current Panel, it shows the Value requested from the Charger, not the Actual Value drawn.
BTW, if you are using the Stock Charge and Yu Yureka phone, then Disable Quick Charge.

Updated (30-10-17)
Changelogs: -
*Now U can Turn off Core-0 - Device probably won't reboot anymore
*Boot using 5 cores. In Details, many users were facing bootloops, because, the kernel was configured to boot on all 8 cores, at max frequency, which was 1612MHz, so this drew a lots of battery power, and weak batteries resulted in bootloops. Remember, Splashloops(Device Looping at YU logo, no bootanimation) is most probably caused by lesser system space <25mB, U have to ensure a system space of 25mB, before reporting it here
*Alucard Hotplug - Added Alucard Hotplug, AND please, use only one Hotplug at once, Either AiO or Alucard;
*Re-Enabled CPU Boost again

Hello Guys,
Many of the YUsers were Complaining about "Battery Drain, Heating and Lagginess" faced, when using Oreo ROMs, e.g. - NitroGen OS, Nougat ROMs like Resurrection Remix etc.
So, I spared some time, looked into the matter and Finally, the kernel has been UPDATED!!!
ChangeLogs :- 15th November, 2K17 {Oreo and Nougat/MarshMallow}
*Compiled Using UBER 8.0.0 ToolChain
*Latest CAF(LA.BR.1.2.9_rb1.27) commits are merged
*UKSM - Ultra Kernel Samepage Merging
Spoiler: UKSM over KSM,
* Ultra KSM. Copyright (C) 2011-2012 Nai Xia
*
* This is an improvement upon KSM. Some basic data structures and routines
* are borrowed from ksm.c .
*
* Its new features:
* 1. Full system scan:
* It automatically scans all user processes' anonymous VMAs. Kernel-user
* interaction to submit a memory area to KSM is no longer needed.
*
* 2. Rich area detection:
* It automatically detects rich areas containing abundant duplicated
* pages based. Rich areas are given a full scan speed. Poor areas are
* sampled at a reasonable speed with very low CPU consumption.
*
* 3. Ultra Per-page scan speed improvement:
* A new hash algorithm is proposed. As a result, on a machine with
* Core(TM)2 Quad Q9300 CPU in 32-bit mode and 800MHZ DDR2 main memory, it
* can scan memory areas that does not contain duplicated pages at speed of
* 627MB/sec ~ 2445MB/sec and can merge duplicated areas at speed of
* 477MB/sec ~ 923MB/sec.
*
* 4. Thrashing area avoidance:
* Thrashing area(an VMA that has frequent Ksm page break-out) can be
* filtered out. My benchmark shows it's more efficient than KSM's per-page
* hash value based volatile page detection.
*
*
* 5. Misc changes upon KSM:
* * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page
* comparison. It's much faster than default C version on x86.
* * rmap_item now has an struct *page member to loosely cache a
* address-->page mapping, which reduces too much time-costly
* follow_page().
* * The VMA creation/exit procedures are hooked to let the Ultra KSM know.
* * try_to_merge_two_pages() now can revert a pte if it fails. No break_
* ksm is needed for this case.
*
* 6. Full Zero Page consideration(contributed by Figo Zhang)
* Now uksmd consider full zero pages as special pages and merge them to an
* special unswappable uksm zero page
*Zen Interactive Tuning: Auto Tunes the kernel for responsiveness at the cost of throughput and power usage.
*Enabled F-Sync
*Decreased time to Enter Sleep Extensively
*Relaxed Governor is tuned a bit!!
*AluCARD HotPlug Updated to Latest Version
*Tuned for more memory
