[Kernel][CM7] 13/04 platypus [request: thread maintainer needed]

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
Click to expand...

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

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.

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.
Sent from my SGH-T959 using XDA Premium App

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.
Sent from my SGH-T959 using XDA Premium App

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
Sent from my SGH-T959 using XDA Premium App

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..

[KERNEL][GPL][8 DEC] franco.Kernel | BLX | DEEP IDLE | LIVEOC

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!

e~~~this kernel will cause the phone cant be wake up when i off the screen ,i am charging right now~~~

[KERNEL][stable: M1 (2.6.39.4) - exp: Alpha 31 (3.1.10)] Kowalski Kernel

This kernel supports both new and old bootloader and apparently it's also the favorite kernel of the MIUI team (****ing thieves...) !
This is not a "phonsole" kernel, it's not made for draining your battery in a nanosecond because "it's cool to play tegra3 designed games on the p990", so there is overclock, but done "The Right Way™".
Our phone is quite powerful on its own, but LG and Nvidia made a really crappy job on optimizing it. I'm just working to make it a bit better and to provide a reliable, stable and battery friendly kernel to all those people who actually use a phone... as a phone...
There are experimental/unstable versions that i release every now and then for public testing. Official kernels are released when the beta testing phase is done and 100% of the feedback is positive. Don't ask for ETA or you'll be fish slapped... badly !. This of course is not valid in case a nasty bug slips in the release, in which case i'll do my best to fix it within a few hours.
Features
* Compiled in release mode (all debug stripped)
* Battery friendly, performance aware
* 3G modem runtime/suspend idle mode support
* Enhanced wifi power management
* Runtime wifi power management control via sysfs
* Bluetooth deep sleep without disconnections
* OC up to 1.2 GHz on stable releases and up to 1.5 GHz on experimentals
* Dynamic FSync by Faux123, backported from Linux 3.4
* 32M ramhack on the new bootloader, 24M on the old one (for now)
* ROW scheduler by Qualcomm, backported from Linux 3.4
* BFQv5 scheduler, backported from Linux 3.4
* Dynamic Interactive governor, backported from Linux 3.2
* Interactive governor aligned with Google's upstream sources (Linux 3.4)
* Simplified cpu hotplug, the second core will turn off in deep sleep mode
* Single/Dual core mode
* Support for notification lights on compatible roms
* Proportional Rate Reduction for TCP to increase network reliability
* Westwood TCP congestion algorithm enabled by default
* Support for NTFS (read only) and HFS+ filesystems
* Support for NFS 3/4
* Support for custom leds brightness from userspace
* Support for USB fast charge [ Don't keep it active when connected to a pc or it may damage your usb ports. It's meant for fast charging when using car/plane adapters for example ]
* And loads more...
* Comes bundled with Kowalski Manager by wfd
Q & A
Q: Battery !!! Why it's so baaaad ! My phone doesn't sleep !!!
A: Well, don't get it badly, it's not really my problem, is it ? 99.999% is an app you have installed that's preventing deep sleep...
Q: App X crashes ! OMG I lost my sdcard ! Noooo all my data are gone !!!
A: Read again on top, not my fault, sorry. I try my best to give out a stable kernel, but "**** happens" and i can't control it...
Q: I get tons of bsods, my phone doesn't wake up from sleep, it freezes and omg... it just exploded !!!
A: No dmesg / logcat, no party. And please don't post messages like those in the thread if you're not ready to attach a log to the post.
Q: When will you enable gpu overclock, road runner speed mode or wile e. coyote immortality ?
A: Never... on a second thought... maybe... who knows ?
Q: When will you release the new version ? It's a week we're using the old one !!
A: Is it stable ? Then please allow me to fish slap you with a huge trout !
Downloads
All downloads for Kowalski Kernel are in this folder on DevHost.
Updates will be pushed to those folders based on the kernel version, and a change log will be filled in the next post accordingly. Kernel releases will be announced in the thread.
The downloads labeled as "kowalski-*-XXX-YYYbl" are obviously the kernels for [YYY=old || YYY=new] bootloader and XXX represents the version number.
* In Kowalski Manager on kernel 2.6.39.4 you can change the power management settings of the wireless card:
- PSP Power Saving Mode ---> your wifi card will use Max PSP when asleep. The kernel default is to sleep in Fast PSP mode.
- Awake Power Management ---> your wifi card will use Fast PSP when awake if enabled, otherwise will use CAM mode.
- Hotspot Power Management ---> when enabling hotspot mode, your wifi card will use Fast PSP if enabled, otherwise the default is to use CAM mode.CAM (Constantly Awake Mode)
Keeps the client adapter powered up continuously so there is little lag in message response time.
Consumes the most power but offers the highest throughput. Is recommended for desktop computers and devices that use AC power.
Fast PSP (Power Save Mode)
Switches between PSP mode and CAM mode, depending on network traffic. This mode switches to CAM when retrieving a large number of packets and switches back to PSP after the packets have been retrieved.
Is recommended when power consumption is a concern but you need greater throughput than that allowed by Max PSP.
Max PSP (Max Power Savings)
Causes the access point to buffer incoming messages for the client adapter, which wakes up periodically and polls the access point to see if any buffered messages are waiting for it. The adapter can request each message and then go back to sleep.
Conserves the most power but offers the lowest throughput. Is recommended for devices for which power consumption is the ultimate concern (such as small battery-powered devices).​Source will be pushed to my github about 2 or 3 days after a release, to make sure that no major bugs are introduced in the public repository.
This kernel can be compiled with any gcc 4.6.X that supports graphite loop optimizations, so if you want to compile it by yourself you'll have either to build your own toolchain (for example using crosstool-ng), or use one of the many linux prebuilt ones (for example Linaro or CodeSourcery). Make sure they're 4.6.X. Earlier versions may complain a lot and generate and unstable kernel. Newer versions (aka 4.7+ won't produce a bootable kernel at all unless source modifications are done).
Please don't rip-off my work. Please don't kang this kernel. Please don't c&p from my github without proper credit. I'm a nice guy, but i will report you.
Thanks
* wkpark for unlocking the ics bootloader and his genius ideas for implementing ramhack
* linus, well, for the linux kernel
* massimo69, stonebear, tetsuo55, wfd and carloit for taking the risks of testing possibly harmful pre-releases
* qualcomm, because codeaurora is awesome !
* benee, for his perfect any-kernel installer !
* wfd, for his fantastic Kowalski Manager App !
* hjunii for forward porting and cleaning up all the LG crap to kernel 3.1.10 !
On a side note... i'm not really responsible if you decide to test it and your phone melts... right ?

007 - 2013/01/13
* Full changelog that lead to this release in my CM10 thread at the second post​
How-Tos
Change the default TCP Congestion Algorithm
To see what algorithms are available you can, in a terminal/adb console, type: "sysctl net.ipv4.tcp_available_congestion_control"
To change the default congestion algorithm, type: "sysctl -w net.ipv4.tcp_congestion_control=one_of_the_names_that_came_out_before"​
Change the Wifi Power Management modes
In a terminal/adb shell navigate to /sys/kernel/wifi_pm.
You can change the high power management setting by typing: "echo 1 > max_pm" to enable it, or "echo 0 > max_pm" to disable it (cam / psp modes).
This setting will enable/disable the PSP power saving mode when the phone is asleep. Be careful, not all the routers are happy with it.
You can change the awake (screen on) power management setting by typing: "echo 1 > wake_pm" to enable it, or "echo 0 > wake_pm" to disable it (off / cam modes)​
Change the leds brightness
In a terminal/adb shell navigate to /sys/class/leds/star_led.
You can change the high value setting by typing: "echo XXX > max_brightness" to modify it, where XXX can be a value between 0 (off) and 255 (max).​
Change WiFi TxPower
Interestingly enough, Broadcom/LG decided that they want us all dead in a very short time so they set the default txpower of the wifi chip to 32dBm (that's a whopping 1.6 Watts in power). Considering that the US FCC sets a top limit of 30dbM/1W for antennae and that the EU sets a max power of 20dBm/100mW for consumer products, i'd say that Broadcom and LG are quite some nice companies... also wonder how they went past controls with this one...
Anyway, i packed a flashable zip that will install the "iwconfig" and "iwlist" binaries to /system/xbin in your phone. After flashing this one you can, from a terminal, modify the txpower value in real-time depending on your needs (if at home 5 mts from the router, or in a park 100 mts from the access point). For now a binary, soon an apk to handle this, so bear with me and wait
You can download the package from here
To check the current txpower value
Code:
su
iwconfig wlan0
To set the new txpower value
Code:
su
iwconfig wlan0 txpower XX (where XX is the value in dBm)
On this link you can find a W -> dBm conversion table that might come in handy
Side notes: 1) To use iwconfig your wifi must be on and 2) When you turn it off/on or reboot, the setting will be reset to 32dBm for now.​
Alsa Mixer
There ya go, for all of you a little deaf that love some real crackling from your phone's speakers
Packaged in a nice cwm flashable zip (alsa_mixer.zip) that you can find here is a collection of binaries that will be installed in /system/xbin and that will allow you to alter a bit the volumes of your phone. Of course you'll have to slap the values that you like in an init.d script once you find them, or they won't persist on reboot.
For example, to boost a bit the speaker volume, you can type: alsa_amixer sset "Speaker" "60" (max is 63) and to see the current setting you type: alsa_amixer sget "Speaker"
I suggest that you look into the alsa_amixer help and experiment a bit with the values. You can't break anything, and a reboot will reset all the values to default ​

First let's try to get a 10 stable, then we move to 10.1... that's the plan and i won't deviate that soon from it.

Hi!, thanks for this release.
I have one question that I cannot answer from the OP... why is there a separate file for the PSP module? Should I flash it after the kernel or it's not mandatory? Is it valid for both BL versions?
Thanks

Awesome, your kernel runs excellent on my O2X(now at 13/01). No SODs whatsoever and very stable since first releases.
If people have SOD problems, it is not always kernel related. I have swapped my device for a new one after lots of black screen issues and with the new one I have almost 0 issues even with the same ROM+kernel.
It seems our device has many different (good and horrible)hardware revisions, I suggest to swap your device at the retailer if it is possible within your warranty.

Updated op. It's valid for both bootloaders and it's not mandatory. The psp module will enable the PM_MAX flag when the phone is asleep, so make sure your router/ap supports PSP mode (if it has a broadcom chip then it does for sure) or your phone will lose packets when in deep sleep.
The gain in battery life though is gigantic... you decide

The Kernel work in P.A.C.Man fine too... Both Bootloader

About led lights I noticed that if I put "always on" with a very dim light this setting doesn't apply system-wide. If I receive a mail with gmail all fine but if I get a text via a third-party app like whatsapp or viber the light goes full brightness (but it respects the "always on" setting). I had to set a custom brightness for every application manually.

F.A.Q. - Read this before complaining!
1. My phone exploded, HALP!
A: I don't answer to problems without a log. The log file is in /proc/last_kmsg. Paste it on pastie.org and link it on your post. Logcats are useless for Kernel purposes, don't bother posting them.
2. This kernel works on Y or X rom?
A: Doesn't work with ROMs having different ramdisk or any derivates due to their irresponsibility of using a different ramdisk which needs patches that break stock rom users. Use a different rom and don't bother me.
3. OMG BETTARY SUCKZ, IT DEAD IN 45 MINUTAS, HALP!
A: As you can imagine I don't build kernels to decrease battery life. All the battery life problems come from your apps, either Facebook, or Maps, or some Location Service being enabled etc etc. Check your damn wakelocks and fix them, the kernel is not responsible for them.
4. How do I flash this?
A: Reading the OP, theres a reason why I added instructions on it.
5. What is a data loss? Did I just had one?
A: Data loss is simply having the connection cut for X periods of time, usually few seconds. Grey bars means the device is not connected to Google services for some weird reason, but you'll still have internet connection.
6. OP is arrogant, I'm gonna call the Internet Police?
A: Deal with it.

Great Kernel
Excellent! Thanks to @DC07 for your great job!
I hope greats news in the future! :fingers-crossed:

Nice work - thanks for that! I really appreciate the minimum frequency and OndemandPlus Nevertheless I got a bug which prevents my phone from going into deep sleep.
Can anyone confirm or provide a fix?

I didn't encounter any problems with the phone going to deep sleep when I tested it bro, I did have problems with the headphones not working but it got fixed... Did you check with WakeBlocker to see which app(s) are not letting it go to sleep?

So I let my phone settle overnight and it goes into deep sleep now. The causing wakelock was PowerManagerService.Wakelock which is now gone. Looks like some app went nuts - thanks for your support, mate!

I guess since 99% of us are already on Android 5.x.x nobody can answer that question, make a Nandroid or use Flashify and backup your current kernel,
if it does not work or behave well you can simply restore your backup/kernel backup and report if it works or not, for other users
cheers

Right. I 'll try later and report. Thanks

Damn, this Kernel is really noice !
I tried it on BlissPop v3.0 - well this ROM is amazingly fast and awesome out of the box but with this Kernel i feel a slightly performance boost.
I had also some little micro animations lags here and there, with this Kernel, they are completely gone and my device is flying as * like never before on Android 5. :good:
One thing though, WIFI does not work, the button to activate it is simply grayed out.

judging by your screen shot, your phone may be in airplane / battery save mode cause low battery, and maybe thats why your wifi may be disabled ?

WiFi still works in Low battery mode, it just restricts the background data from the apps. He is also not in Airplane Mode because we can see full signals for the SIM Card, and it would have been an airplane logo in place of that.
I've tested it too, No WiFi but other stuff works perfectly, not to mention the performance is also good.

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
