RIN Kernel for D850
Close to stock with some sugar added ... delicous!
Hey guys and girls,
you may have seen my unified stock kernel thread already (or may not, but doesn't matter). This kernel is my attempt to build up on the fixed source and add some additional features for us mod lovers to thinker with and to personalize your device to your usage. For now, I'll keep it close to my stock source and just pull some additional features and fixes in, but not to much. That may change in the future (maybe even soon), but for now, I'll stick to that paradigm.
First of, DISCLAIMER, I'm not responsible for bricked devices, dead unicorns, rainbows with missing colors, world war, nose bleed, void warranty (you know that already, don't you? your warranty is void now and it's your fault ) or any other harm happening to your device, you or people around you!

How to apply it?
IMPORTANT: Read through all the requirements, steps and warnings before you do anything, if any requirement doesn't match or you don't know what one or more of the steps below mean or do, ask before you do any of them, if you don't know how all the steps can be done, let it be and wait for the bootloader unlock, I warned you, if you don't do and something bad happens, I'll just laugh at you!!
Requirements? Yes!

How to boot the kernel?
Plugin your device to the PC
Open a terminal and execute
Code:
adb shell # open a shell over adb
su # change to superuser
dd if=/dev/block/platform/msm_sdcc.1/by-name/laf of=/storage/external_SD/stock-laf.img # backup the stock download mode to your external sd
exit # exit the superuser shell
exit # exit the adb shell
adb pull /storage/external_SD/stock-laf.img . # backup the download mode image from you external sd to the PC
adb shell
su
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf # remove the stock download mode
BEWARE, THIS WILL REMOVE YOUR DOWNLOAD MODE!!! YOU WON'T BE ABLE TO FLASH KDZ FILES BEFORE YOU RESTORED IT!!!!
Turn off the device completely, plug in the USB-cable, if you pulled it out and start the device by holding vol up + power till you see some white text on the screen, fastboot should be written somewhere on the screen, afterwards execute the following command on the PC (while in the directory you've downloaded the kernel image to).
D850:
Code:
fastboot boot D850-rin-1.6.img # boot the kernel
BEWARE, NEVER USE FLASH AT FASTBOOT ONLY BOOT, IT WILL TRIGGER SECURITY OF THE LOCKED BOOTLOADER AND YOU WON'T BE ABLE TO BOOT ANYMORE!!!!
You're done now and booted to the custom kernel!
How to make sure you're running the kernel?
To check if you properly booted into the kernel execute this in the command line (terminal emulater or through adb shell):
Code:
cat /proc/version
it should show
Code:
Linux version 3.4.0-rin-g58903a9-dirty ([email protected]) (gcc version 4.9.1 20140710 (prerelease) (crosstool-NG linaro-1.13.1+bzr2673 - Linaro GCC 2014.07 - Cortex-A15) ) #53 SMP PREEMPT Thu Aug 14 13:26:42 CEST 2014
Once more a warning READ IT!!:
BEWARE, when you reboot you'll boot to the stock kernel, you'll have to boot the custom kernel over fastboot every time, when you boot normally, you'll be on the stock kernel, this won't lead to issues, but you'll miss the benefits of this kernel, I know that's not optimal, but the best we can get with the locked bootloader.
How to restore Download mode?
Code:
adb shell # open a shell over adb
su # change to superuser
dd if=/storage/external_SD/stock-laf.img of=/dev/block/platform/msm_sdcc.1/by-name/laf # restore the stock download mode from the backup on your external sd

Please don't quote whole OPs...
Are you sure you took the right file? Just from saying "that's the procedure I've used" I can't tell, sorry, if that's exactly how you've done it, it has to work, as for anybody else, if you did something slightly different, you need to tell.

Have you tried using any other toolchain? I came from arrrghhh's anykernel, which was built on SaberMod, which was very snappy as compared to Linaro in my testing.

Yes, tried sabermod already, it's just even stricter than linaro at compiling, have to change a bit stuff, to be able to compile with it, but it's already on the schedule.

Kernel Version Info
When I go to "Kernel Version" under "Software Information" it shows the Kernel Version as 3.4.0
Is this normal? Or is it supposed to say "Rin Kernel 1.7.1"?
What is the most efficient or favorite setup for Kernal
Thanks for getting a flashable zip file out! I was waiting for this because I didn't want to risk messing something up with the original installation method. From what I have read, people really like the kernel. I'm DLing it now!
OP. Any plans to make custom kernel's for AOSP Roms?

Ok, thanks. I was wondering because I've flashed kernels in the past that display a custom kernel version i.e. "Dorimanx"
I believe the kernel version that is displayed can be changed in the build.prop
Anyone care to post their stable settings for this kernel? I remember a similar thread for the S4 which really helped guys like me who aren't real familiar with all of the different kernel tune-ables.
I've searched the dev thread and this one but didn't see any reports about icon themes reseting after reboot. I finally flashed this kernel tonight and each time I've rebooted after tweaking cpu freqs, the icon theme I'd applied using Nova Launcher reverts back to default icons. I've been on stock kernel since July and this has only happened since flashing this kernel a few hours ago. Any ideas?

I'm using Nova with some alternate icons without issue. Don't know what to tell you except it's working fine for me.
Problem solved and it wasn't anything kernel related. I forgot that I was playing with moving apps to SD the other day and moved all of my icon packs. Apparently, regardless of the launcher being used, it will load before the SD card initializes, so the icon packs aren't found. I've moved then back to the phone and all is well. Google is definitely my friend.

Noma kernel for Huawei U8150
I'm introducing my custom kernel for Huawei U8150 IDEOS phones. In Kenyan Swahili noma usually means "tight," as in: "That music is tight!" It can be used in other ways too, but I like this connotation the best.
GoalsMy aim is to learn about Linux kernel internals, practice software development using git, and to share with the community. In addition to that, I want to explore and test tweaks which lead to increased/optimized performance on this bargain phone (it's very popular in Kenya). Some of the areas of improvement I have in mind are:
CPU scheduling (UI responsiveness, reducing lag)
CPU frequency scaling governors (smartass? ondemandX? interactiveX?)
I/O scheduling and filesystems (flash disk performance, throughput, latency, maybe simpleio scheduler?)
Security (network, local)
Newer drivers (mainstream, community kernel sources)
Newer GCC compilers (CodeSourcery, Linaro)
Easy rooting
Integrate ClockWorkMod Recovery
Integrate busybox
Explore different compression algorithms (LZO, gzip, LZF, etc) for zImage...
Compcache (zram) (info, announcement)
SLOB memory allocator for better memory allocation? (info)
Current features
Code:
- multi-touch gestures (on devices with [url=http://mjanja.co.ke/2011/08/does-your-huawei-u8150-support-multi-touch-gestures/]supported hardware[/url])
- over/under clocking of CPU frequencies
- Tiny RCU ([url=https://lwn.net/Articles/323929/]info[/url])
- BFQ I/O scheduler ([url=http://algo.ing.unimo.it/people/paolo/disk_sched/]info[/url])
- simpleio scheduler ([url=https://github.com/erasmux/hero-2.6.29-flykernel/wiki/Smartass]info[/url])
- "ck" patch set, including the Brain **** CPU scheduler (BFS) ([url=http://www.kernel.org/pub/linux/kernel/people/ck/patches/2.6/2.6.32/2.6.32-ck2/]info[/url])
- optimized memcopy/memmove ([url=https://github.com/alanorth/kernel_huawei_u8150/commit/871656cbba8ee70d0896ac5cae35a31c2e0873e3]info[/url])

Source code
I respect the GPL (the license covering the Linux kernel), so all the up-to-date source code for this kernel is available on github. My kernel is, in turn, based on the publicly-avaiable Froyo kernel sources from Huawei. You're free to fork, modify, and re-release the code as your own, but you must provide the source code for your resulting work. Doing so ensures you honor the terms of the license, but you're also giving back to the community. Basically, don't be a ****.
Credits
I've written zero lines of C code for this kernel. My work is merely to search for interesting modifications to the Linux kernel and add them to a git repository. The real work has been put in by the following people:
Linus Torvalds and all the other Linux kernel hackers around the world
tj_style (multi-touch gesture support)
Stefano Viola (over/underclock)
Renaud Allard for his Galaxy S awesome sauce (kernel, initramfs, etc)
Erasmux (smartassV2)

I usually just flash from fastboot lately, as I'm between ROMs too much and I don't bother installing a custom recovery. I suppose I should modify my build scripts to make recovery-flashable zips... hang tight!
... or, if you can't wait, check out my in-depth blog post about compiling and flashing custom kernels on Huawei 8150. I wrote it a few weeks ago when I was a U8150 n00b.
v47 (20110823)
Changes in 20110823v47 (from the git commit log):
Add new, lookup3-based jhash. See: http://burtleburtle.net/bob/hash/doobs.html
pids: fix a race in pid generation that causes pids to be reused immediately
lib/decompress_bunzip2.c: fix checkstack warning
kbuild: drop unifdef-y support
net sched: fix some kernel memory leaks
net/ipv4: Eliminate kstrdup memory leak
Add noma_defconfig. `ARCH=arm make noma_defconfig` to use.
Mostly security and memory leak fixes. The new jhash implementation is based on lookup3.c, a newer, more-efficient implementation (more info here). It's mainly used in the kernel's ipv4 and ipv6 stacks, so don't expect revolutionary performance increases, but it's backwards compatible with the old implementation, so it couldn't hurt to include it.
Default IO scheduler is now deadline (the same as stock Huawei) until I can do some performance tests of other schedulers on this device. Note: I've included BFQ, Anticipatory, CFQ, and noop as well, so you can use those if you like!

v49 (20110824)
Changes in 20110824v49 (from the git commit log):
Default to ZLO compression of kernel and ramdisk. LZO has roughly the same (but worse) compression, but is much faster to decompress.
Add LZO compression support for initramfs and old-style initrd
Add support for LZO-compressed kernels on x86
Add support for LZO-compressed kernels for ARM
Add support for LZO-compressed kernels
LZO compression is not as efficient but should be faster than the default compression (gzip), which should improve boot time. See: http://free-electrons.com/blog/lzo-kernel-compression/.

Why are you working on Froyo and not on Gigerbread?
Why I'm still working on Froyo
unknhawk said:
Why are you working on Froyo and not on Gigerbread?
Click to expand...
Click to collapse
As this is basically a research project (for both me and the community), the primary reason I'm still "working" on Froyo is that most U8150s are still running Froyo. It's an incredibly popular phone in Kenya (maybe 250,000 - 500,000 units sold?), but I have a hunch very few of them are running non-stock ROMs. Sure, CyanogenMod 7 has a fairly-active U8150 port in progress, but it's not widely used yet.
Like I said, this is primarily a research project, so I'm experimenting for my own curiosity. A part of that is to help people get into Linux kernel, Android, and open-source software development. I want to help set an example of openness, collaboration, documentation, etc.
Also, a lot of the mods I'm making can just as well apply to Gingerbread when we finally get there.
Custom kernel booting on U8150 CM7

Click to expand...
Click to collapse
Fun times... I just got a custom kernel to boot on CM7. It's nowhere near as usable as tilal's kernel, but it is a good exercise. More info here on my blog.
I suppose that whenever I get bored enough with Froyo I could always hop over to CM7. AOSP is where my heart is anyways.
v56 (20110827)
Changes (from the git commit history):
Add su, Superuser.apk, and busybox. This kernel/boot.img will now actively root Huawei stock ROMs.
Remove pre-zipped ramdisks as they are now generated on the fly from the compile scripts.
Correct the name of the compressed ramdisk (mkbootfs technically creates a cpio archive, which I then zip).
Make sure `make clean` doesn't delete our pre-compiled wireless module.
Add mkbootfs for creating ramdisks, and update compile.sh to create ramdisks on the fly instead of using a pre-zipped one.
Add ramdisk from U8150 V100R001C18B842
The build system is now a little more flexible and generates ramdisks on the fly. This should make it more powerful and complete. I've also included su, Superuser.apk, and busybox to enable a very cool new feature: rooting! If you haven't forked or cloned my kernel repository yet, what are you waiting for?
Regarding "rooting," forget what you've heard (it's probably wrong). Here's what it actually means:
Copying the su binary to /system/bin/su
Copying the Superuser.apk application to Superuser.apk
Period. What this means is that Android applications can call on the su binary whenever they want to do perform system administration actions (ie, not normal user actions), such as removing system applications with Titanium Backup. The Superuser.apk application is simply a frontend for su; whenever an application tries to execute su, a Superuser dialog pops up asking you to allow or deny the request. This notion, known as "privilege separation," is a common one in all operating systems.
Download: noma_20110827v56_boot.img
v83 (20110903)
Changes (from the git commit history):
sched: export nr_running symbol for use by smartassV2 CPU governor.
config: sync with latest config
sched_fair: Restore less extereme latency values (latency of 6ms)
sched: enable HRTICK
sched_fair: Enable HRTICK
cpufreq: add smartassV2 governor
Switch busybox, older version (1.18.4) but slimmer, more appropriate for our needs (from https://faramir.eriador.org/r/).
Minimum frequency to 122MHz at boot, as well as smartassV2 governor.
Optimized ARM RWSEM algorithm
Cleanup after installation of su stuff. We're on a ramdisk after all, we need to conserve memory.
Change location of root stuff so it isn't in the $PATH
Add Simple I/O Scheduler
Add V(R) i/o scheduler
Update to latest Linaro GCC 4.6 compiler.
Two major changes are the addition of the simpleio IO scheduler and the smartassV2 CPU governor. The simpleio scheduler is based on/around the noop and deadline schedulers, designed specifically with non-rotating media in mind (flash disks, hello!). The smartassv2 CPU governor controls how your CPU switches between frequencies (from 122MHz at idle to 672MHz when in use). I haven't done any benchmarks, but these should improve responsiveness and battery life (in theory at least!).
Other than that, the latest Linaro GCC 4.6 compiler, some small optimizations to ARM-specific functions, and ramdisk/boot cleanups. If you're curious about smartassV2 there's more info here, on erasmux's github page here.

cm7 nightly bugged one ?????? i dnt like it iz there iz n e fixed cm7 for ideos ????
btw your kernel doesnt works with cm7 and can u please make a kernel for samsung galaxy gio with smartass v2 ??
Aorth, I tried flashing you kernal, and unfortunately there is one error when flashing with the latest CM7.1. After the flash, the phone will be stuck at the boot screen. I was wondering if you can get this fixed, that'll be great
This kernel is meant for stock ROMs

Yeah, this kernel was really meant for Froyo stock ROMs. It won't work on CyanogenMod builds because the ramdisk's init scripts are not compatible.
My U8160 kernel repo has a kernel which works on CM7... but you'll have to compile it yourself
nice kernel ........... working fine on ideos u8150-B .... I flash it with stock rom ................. battry becomes efficient ...
Good Job!
Hello aorth,
I'm now using the LEANdroidMOD 5 based on your kernel and I have to say the name NOMA suits it to a tee. It's my default ROM now when I'm not testing your or tilal6991's builds. Thanks and you have yourself a happy holiday season!
hello,
will there be any update of your noma kernel? this is my fav because all roms out there eat my battery like mad, so i just use your kernel and i'm happy with it
greetings
oh man please update, this is one nice kernel!
CM7 u8150 april 5th
IS this already built in to your CM7 last updated april 5th rom or is that a diffrent kernel? which one is better? would it be hard to install it on that rom? whats the advantages over the built in cm7 rom? Thanks sounds awsome anything to make that baby faster is great. Good work
SU Binary Outdated notification
flasehd v83 on the stock 2.2.1 kenya 1 mutli touch rom all went good but whenever i restart the phone su binary shows the notifications bout su binary being outdated which i updated , i did it multiplie times but it comes up everytime the phone is rebooted , other than that su binary working ok ,
dont know how to fix it , other than that the phone is working so responsive , enjoying it
when i flashed the kernel , the phone was already rooted

Steps for Multi boot:
1) Flash Kernel v1.7+
2) Go to CWM Recovery -> Multiboot -> Backup ROM.
3) Backup your Current ROM to ROM1 (It will backup the system.img at /sdcard/Android/data/g3mod/romname_ROM )
4) Add the system.img of your 2nd ROM to /sdcard/Android/data/g3mod/romname_ROM and similarly for different ROM's.
5) Use the CWM Recovery -> Multiboot -> Switch ROM option to switch between different ROM's.
Note: Ask the developer of the ROM's to provide you with the system.img for their ROM
System Img's:
CyanogenMod 6.2 Alpha 4 System.img
Steps for Changing the Max Freq(Dynamic OC):
There is an entry in /sys/devices/system/cpu/cpu0/cpufreq/plls_table where you can put your own value for APLL.
Before doing this, set "PERFORMANCE" governor on and min and max frequencies to the maximum.
Code:
// Do this in adb
echo "0 a[SIZE="5"][B][U]258[/U][/B][/SIZE]0[SIZE="5"][B][U]3[/U][/B][/SIZE]01 a14d0303 c07e13fc cf850240" > /sys/devices/system/cpu/cpu0/cpufreq/plls_table
You need to replace the 258(Hex Value) with your desired value.
Here 258 means
(2*16*16) + (5*16) + 8 = 600
and 3 means it is 600*2 = 1200
Therefore, a2580301 means 1200MHz.
This is a temporary method. For a permanent Method, add this line to a init.d script. Name the script to something like S10_Dyanmic_OC.
Help Others: If you calculate a Hex Value for a particular frequencies add it here:
https://docs.google.com/spreadsheet/viewform?formkey=dG5hdnpsWFdTNExiY2t3dy16VzBvaWc6MQ
You can view all the frequency Hex value's calculated by others over here:

Note:
I am learning how to develop kernels.
I'll add different features as and when i can implement them.
The main goal of this kernel will be to keep the phone stable and fast.
There will be nothing as alpha or beta releases.
I'll give out the kernels directly, but if anything goes wrong and you have to reflash the ROM or kernel, please dont start shouting.
You may give me different ideas on what features to implement. I'll try my best to implement all the features you want
Many of the features implemented in this kernel, are taken from marcellusbe's Fugumod Kernel, and I shall be ever thankful to marcellusbe for the fugumod kernel

Too Good Dharam Bhai
sounds great i am looking forward to that
Good to have a separate thread
Am using the test version currently , seems good
Do we have the img file of CM6.2?
This is very very good work Dharamg3
Thank you man
as I fu..... up my whole system trough UV-experimenting (crashing with destroying FS) I'm gonna flash CM6 with the test kernel now...
[Q]: Is it possible to put the test-kernel CM6 zImage into an old-style kernel-update-ZIP without problems?
Wanna be PC independent when changing systems

yes, i think update.zip should work...
Strange bug, either test kernel, either CM6.2 related (however did not happen before): I was browsing in the afternoon with Opera Mobile and XDA app via GPRS, and suddenly my phone gave a strange beep, vibrated fast two times, and shut down. The shutdown toast blurs the other parts of the screen beyond readable, but I think there was a "Connect charger" error message and the battery icon was red. After turning back on the phone, the battery was near full.
It happened twice in about 10 minutes, now it seems it's gone. I tried to check the dmesg output, but unfortunately it did not contain any messages before the reboots.

Update 2013-03-05 (3.1.10that4):
The latest kernel is up: http://forum.xda-developers.com/showpost.php?p=38797590&postcount=194
New features: User voltage control and Data2SD auto-detection.
End Update 2013-03-05
Update 2013-02-06 (3.1.10that2):
After positive feedback from testers and due to popular demand, here is my latest kernel with the experimental new "ROW" I/O scheduler. If you want to know more, read the documentation in the patch here: https://patchwork.kernel.org/patch/1862241/ . Please note that this is a rather new development and not yet merged into a mainstream kernel, so it has not been widely tested. However, all results from XDA members were neutral or positive so far.
End update 2013-02-06
Since Asus seemed to have forgotten to release the 10.4.4.25 kernel sources, I reminded them politely - and finally the sources are available for download from their support site!
This is the first kernel ever that I cross-compiled myself - be gentle.
zImage (kernel binary) features:
- Asus 10.4.4.25 base
- fsync control
- ISO 9660 + UDF support (CD/DVD filesystems)
- CIFS (for mounting Windows shares)
New in 3.1.10that2 (2013-02-06):
- ROW I/O scheduler (prioritize READ requests over WRITE requests on eMMC/SD cards) included as default
New in 3.1.10that4 (2013-03-05):
- User voltage control for undervolting
New in 3.1.10-10.4.4.25-that5 (2013-03-24):
- Penguins! (framebuffer console)
New in 3.1.10-10.4.4.25-that6 (2013-04-01):
- No more crash when reading /sys/bus/nvhost/drivers/tegradc/tegradc.0/nvdps
Ramdisk features:
- insecure adbd
- init.d support
- does not set lcd_density (dpi unlocked)
in the -data2sd versions only:
- mount points modified for the Data2SD mod (see http://forum.xda-developers.com/showthread.php?t=1962507)
New in 3.1.10that4 (2013-03-05):
- auto-detection of data2sd - if the microSD card is inserted at boot time and it contains a second partition, it is assumed to be a data2sd partition and mounted as /data. Otherwise, the system is booted with /data mounted to internal storage as usual.
New in 3.1.10-10.4.4.25-that5 (2013-03-24):
- moved auto-detection of data2sd to scripts in /system for easier customization (read the release post for details)

(You might now ask "where is the overclocked version"? I decided to start with a known stable base for my first release - if this one turns out to work fine, the oc build comes next.) - for overclocked version, read next post!
Overclocked!
This is 3.1.10that1-oc - the version with clemsyn's overclocking patches. Please note that I only extracted and then applied his patches to the current kernel and typed "make" - I don't understand all the scary frequency and voltage tables, and I don't know how it works in detail. However I got up to 7130 points in this benchmark thingy, and system tuner shows 1.8 GHz, so it appears to do something.
Please note that this is only the kernel, and it does not contain clemsyn's changes for the Asus performance modes. As you may know, the 3 Asus performance modes are activated by running shell scripts in /system/etc named cpu1.sh to cpu3.sh. Clemsyn's kernels replace balanced mode with performance mode, and performance mode with the new overclocked mode. This kernel does not do that, it leaves your modes as they were!
Depending which kernel you were using before, the following will happen:
- Coming from a stock kernel, you keep balanced and performance modes, and the extra overclocking mode can only be activated by executing /system/etc/cpu4.sh. If you want, you can rename cpu2.sh to cpu2_original.sh, cpu3.sh to cpu2.sh and cpu4.sh to cpu3.sh, then you have performance mode as default instead of balanced, and overclocking mode if you activate "performance mode" - same as clemsyn's. If this is too complicated for you, you can either flash clemsyn's kernel directly before this one, or wait until someone repackages this kernel.
- Coming from clemsyn's kernel, performance modes should work as before. Please don't ask me which specific variant of clemsyn's kernels this one is comparable with - he released only one source package, which I used, but many different kernel binaries. I can't recreate other versions without clemsyn releasing sources for those specific versions.
zImage (kernel binary) features:
- all of the above
- Overclocking and voltage control
Ramdisk features:
- same as non-overclocked version
Additional credits:
- clemsyn, for his amazing overclocking kernel

Same zImage with the ramdisk from the previous data2sd kernel.
Note: this is not a data2sd installer, it's only a new kernel to drop into an existing data2sd installation.
Working well so far! :good:

Great news! Your new data2sd kernel is working very well. All data mountings are correct and fsync is woring wonder! Great job!
1. When PC hook up to device, on PC I see:
a. Internal - ext4 parition on microsdcard
b. Micro - Fat32 partition on microsdcard
c.-SD - Dock SDcard.
2. Disabled fysnc - working wonder, gain 600+ on Quadrant.
I have been using Sandisk Extreme Pro class 10 (95mb/s) and it's very stable (Did not work before with Clemsyn Kernel). With fsync disabled, a gain of 600 point bring Quadrant to 6639 from 5995/6005 without OC. The tablet is super smooth and fast with fsync disabled. I can see the apps are launching faster from stand still, if they already in memory, BAM it's there. Browser also faster, Gallery loaded much faster and I got over 2 thousand pictures. In summary, I'm impress and very happy....just couldn't wait for the OverClock version.. Again, great job _that!! :good::good:
Edit: I will be running this for a week to see if any issue with journaling and fsync disabled on this super fast sdcard. Will report back.
Update 1/30 @ 10:30pm est - After 4 1/2 hrs, this tablet stills running smooth and quick. Very happy with this kind of performance, probably the best to date. What I'm really exciting about is, there still more room for performance....when "_that Overclock kernel" arrived..
tried this on PA, and I get a message, upgrading apps, but then it hangs. Is this to work on all ROMS, or just stock?

Should be just for stock Cleanrom.
Tried this fantastic kernel in the last 5 hours and it is smooth, had no problem at all. Epic Citadel reports a benchmark of 38.9 fps.
Can't wait to try the OC version of it. Also waiting for the SanDisk Extreme to arrive from Amazon to try out the data2sd too.
Re: [KERNEL] 3.1.10that1 ★ 10.4.4.25 + fsync + ISO9660 + CIFS
I can confirm that data2sd version is working great. Waiting for the OC version. Good job!
So how does one disable fsync?
Flash this kernel, reflash ROM with no kernel option and fsync disable checked, or?
Just flashed this kernel. I have disabled fsync and my tablet has sped up. Thanks for this kernel _that.

1. Reflash CleanRom 3.2.1
2. Disable Fsync during the installer
3. Reboot
4. Wipe Devlink Cache/Cache
5. Flash this kernel
This should disable fsync with this kernel.

Hello i just want to say thanks, i am using the data2sd version without any problem.
If someone is interested in the kernel changes between 10.4.4.23 and 10.4.4.25 can follow this link to my github.
Looks like Asus has made some changes in the mmc management:
Code:
/*
* SD Workaround: downgrade frequency for seldom specific sdcard
*/

Sure, that's the point of me publishing all the sources as detailed as I can - take whatever you can use.
By the way, there is a nice script in the kernel sources that extracts a config from a zImage, it's in scripts/extract-ikconfig and you pass a zImage to it as a parameter. Maybe that's useful for you one day.

Excellent. Note I mod Clemsyn's cpu.sh files so that balanced mode is balanced mode which theorectically means I can now make a 1.3 1.8 and a 1.5 1.8 version of this
Off to do some testing.
Looks like Kernel Installer 1.8 is in the making.

Nothing like quoting yourself. Yes it works. Now running a 1.3 1.8 GHz version of this kernel
Many thanks _that. Time to thank you with a donation. :good:
Hey all,
This kernel works on stock 4.2 ROM's only.
Disclaimer
This kernel, in any way, won't make your device fly or break antutu charts. What I can only promise is a consistent performance with reliable battery life.
Instructions:
flash zip in recovery
Features:
Integrated CWM
Linaro 4.9.1
kexec hardboot support
Full SELinux Support with upstream fixes
Userspace voltage control
Updated prima wlan with CAF fix for delayed notifications
1.2 GHz max frequency
More GPU clocks with optional overclock to 450 MHz
CAF backport fixes
vibrator intensity control
Kill debug wherever possible to reduce overheads
general tweaks here and there
Note: For full in-depth info, checkout my commits and release notes. I am not huge fan of bloated feature list since end-user may find it too difficult to grasp.
Although every feature is controllable through sysfs, I would still recommend trickster mod or kernel tuner app for tweaking.
Kernel will boot with my recommended settings but you can change them if you know what you're doing.

Release Notes
1. r1
* Initial release
* Hotplug driver: This kernel uses stock mpdecision by qcom. I won't be switching to other custom hotplug driver in a foreseeable future.
* Single initrd: I wasn't happy with standard method of packing two ramdisks inside an initrd. This caused unnecessary cpu overheads while decompressing boot ramdisk especially heavily compressed ones like xz and rewriting data to rootfs /. So I forked a process from init.rc to detect keychecks and exec recovery init from stock initrd itself. This improves upon the situation above by having everything we need in stock initrd itself. Boot times also become relatively shorter. I would recommend kernel developers to switch to this method.
* Kexec Hardboot : zip will automatically install all required kexec binaries.
Place your zImage and ramdisk.img in /sdcard/kexec/* and in terminal type:
do-kexec.sh
kexec -e
* Vibrator intensity control:
sys interface is located at /sys/devices/virtual/timed_output/vibrator/level
* Updated Prima: Stock fw used ancient prima 3.2.1.1h. I upstreamed it to 3.2.2.0 with CAF fix for delayed wifi notifications.
* sched_mc_power_savings = 1
Tries to group tasks into least cores possible. Battery friendly. 1 is moderate. 2 is extreme. 0 disables it.
* Userspace voltage control by @faux123:
I modified the original code by introducing a useful pr_info to actually output voltage change requested in mV. Also some cosmetic conditional and looping changes.
To determine the last voltage change, type dmesg | grep requested
The sys interface is located at:
/sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels.
Sample command to decrease voltages at all frequencies by 10mV
echo "-10000" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels
By default, kernel comes with 20mV undervolt.
* patch CVE-2014-0196
* add row and sio iosched
* Enable writing to hardware rtc
* More gpu scaling levels : 450 MHz and 128 MHz
* External modules.zip : cifs.ko, ntfs.ko, nls_utf8.ko, hid-sony.ko
* HID driver for Sony / PS2 / PS3 BD devices : hid-sony.ko
ramdisk will automatically insmod it if found.
* VM_MAX_READAHEAD512
* sched: LOAD_FREQ (4*HZ+61) avoids loadavg Moire
* lib: Update RWSEM to Linux 3.10
* lib/int_sqrt.c: optimize square root algorithm
* enable some more TCP Cong methods
* deadline tweaks
* partially nuke cci stuff
* switch to noatime and nodiratime
This option stops recording the last file access time when the file is just read. The noatime option eliminates all the writes to the disk each time a file was just read which previously used to happen with atime. However a write is made to a disk in case if a file is being changed/written. Easy on cpu and battery.
* tick: Upstream fixes
* xz compression for zImage ( best compression ratio ) and gz for ramdisk
* kill debug such as DETECT_HUNG_TASK, DEBUG_ATOMIC_SLEEP etc. which cause unnecessary CPU overheads
* enable adb RSA authentication
ro.adb.secure=1
* ro.debuggable=1
* Various CAF backport fixes including fixes to SELinux
Please don't ask for:
1. Anything that ends with *to-wake/sleep/dance
Got a bug?
cat dmesg and pastie me.

Hello everyone. I tell them that I decided to try this kernel. Return to the stock ROM, take a few hours and the phone is going well, really feel the change, note the phone faster, more stable, the battery has performed very well so far no trace of the sensor bug the only bad thing as it is that if we turn off the phone's date and time settings are lost.
i need flash external modules too?? *unsure*
for now i flashed vengeance zip only ... how to fix date error?

Why some heavy 3d games have random stuttering effect after some time of playing them.. (frontline:commando 2 for example)
When i clock it to 1188 it does give me that lag free performance of some heavier games compared to stock kernel. (actuly it gives me the best performance in terms of gaming.... beats almost all other kernels. Even thunderzap and phantom can't reach this type of smoothnes in terms of gaming...but then again its custom 4.4 so i got used to lag).
Games runs amazing on 1188 but after some time it just get random freeze and start stuttering...can't even get to handle my phone to quit from the app because it wont get back to normal)
Any specific solution to this problem?
PS: Im back on stock because it doesn't have this issue with stuttering and if it does it only last for few seconds but the performance is quite lower then vengeance...

PS: Im back on stock because it doesn't have this issue with stuttering and if it does it only last for few seconds but the performance is quite lower then vengeance...

It has nothing to do with gov settings...
I encountered this with older version of phantom or thunderzap for JB also but never had it on kitkat.
Problem is that current kitkat kernels doesn't give that much of a boost in termps of gaming..... (atleast not for me)
I remember Varun mentioning about flashing the kernel immediately after u flash the ROM file, ftf in this case. Try that. Also means you will have to format your device.
Great Kernel

Strange. I just rebooted my phone and there's no reset. Maybe I'll investigate later. I have been busy lately. [emoji1]

Greetings friend, I congratulate you for your great contribution, I am testing and everything is going well. In my case also is being presented the problem that I lose the time and date settings every time I reboot the phone. addition also happens that my manager asks me root file permissions every time I go to do some operation (copy, paste, etc.) and folders are appearing very strange names in both internal and external memory. Thanks for your help.
Yep, date and time resetted every boot. Just like the old version of Thunderzap JB bugs. I think Varun has already fixed that.
RIN Kernel for D850
Close to stock with some sugar added ... delicous!
Hey guys and girls,
you may have seen my unified stock kernel thread already (or may not, but doesn't matter). This kernel is my attempt to build up on the fixed source and add some additional features for us mod lovers to thinker with and to personalize your device to your usage. For now, I'll keep it close to my stock source and just pull some additional features and fixes in, but not to much. That may change in the future (maybe even soon), but for now, I'll stick to that paradigm.
First of, DISCLAIMER, I'm not responsible for bricked devices, dead unicorns, rainbows with missing colors, world war, nose bleed, void warranty (you know that already, don't you? your warranty is void now and it's your fault ) or any other harm happening to your device, you or people around you!

How to boot unbumped kernels?
Only needed for the img files prior version 1.7
Plugin your device to the PC
Open a terminal and execute
Code:
adb shell # open a shell over adb
su # change to superuser
dd if=/dev/block/platform/msm_sdcc.1/by-name/laf of=/storage/external_SD/stock-laf.img # backup the stock download mode to your external sd
exit # exit the superuser shell
exit # exit the adb shell
adb pull /storage/external_SD/stock-laf.img . # backup the download mode image from you external sd to the PC
adb shell
su
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf # remove the stock download mode
BEWARE, THIS WILL REMOVE YOUR DOWNLOAD MODE!!! YOU WON'T BE ABLE TO FLASH KDZ FILES BEFORE YOU RESTORED IT!!!!
Turn off the device completely, plug in the USB-cable, if you pulled it out and start the device by holding vol up + power till you see some white text on the screen, fastboot should be written somewhere on the screen, afterwards execute the following command on the PC (while in the directory you've downloaded the kernel image to).
D850:
Code:
fastboot boot D850-rin-1.6.img # boot the kernel
BEWARE, NEVER USE FLASH AT FASTBOOT ONLY BOOT, IT WILL TRIGGER SECURITY OF THE LOCKED BOOTLOADER AND YOU WON'T BE ABLE TO BOOT ANYMORE!!!!
You're done now and booted to the custom kernel!
How to make sure you're running the kernel?
To check if you properly booted into the kernel execute this in the command line (terminal emulater or through adb shell):
Code:
cat /proc/version
it should show
Code:
Linux version 3.4.0-rin-g58903a9-dirty ([email protected]) (gcc version 4.9.1 20140710 (prerelease) (crosstool-NG linaro-1.13.1+bzr2673 - Linaro GCC 2014.07 - Cortex-A15) ) #53 SMP PREEMPT Thu Aug 14 13:26:42 CEST 2014
Once more a warning READ IT!!:
BEWARE, when you reboot you'll boot to the stock kernel, you'll have to boot the custom kernel over fastboot every time, when you boot normally, you'll be on the stock kernel, this won't lead to issues, but you'll miss the benefits of this kernel, I know that's not optimal, but the best we can get with the locked bootloader.
How to restore Download mode?
Code:
adb shell # open a shell over adb
su # change to superuser
dd if=/storage/external_SD/stock-laf.img of=/dev/block/platform/msm_sdcc.1/by-name/laf # restore the stock download mode from the backup on your external sd

Any questions? (FAQ)
How can I toggle the android logger?
File Explorer Method:
Go with a root explorer to /sys/kernel/logger_mode and open the logger_mode file.
Remove everything inside that file and put the number 1 to enable and 0 to disable the logger into it and save the file.
Terminal Method:
Enable the logger
Code:
echo 1 > /sys/kernel/logger_mode/logger_mode
Disable the logger
Code:
echo 0 > /sys/kernel/logger_mode/logger_mode
My internal sd is not working, what to do?
Open adb shell or a terminal emulator and type
Code:
su
restorecon -v -R /data/media
Cool. I am not into kernels UT that KS for extending support to the D850.
Wow nice congrats
Will this be easier to use once the Bump! Support is added?!
I will try it out now, but it will be able to be permanent once it is able to be Bump!'ed right?

Yes, as soon as the bump method is released I can build a flashable and you can flash it through recovery like usual and don't have to worry about booting it through fastboot.

Thanks for brining your kernel to us. This is a great day for AT&T!!!
Would flash image gui tool be able to flash this for us? I used it before on other devices

When I flash this one, I end up going to a green screen saying HW Reset. I got options to go into Download Mode or reboot. If I reboot, the Kernel doesn't get booted.

Interesting, just out of interest, to which version did you update through ota?
Could you try to remove the laf partition to get to fastboot mode and boot to it?
(just replace recovery with laf at the steps to remove the recovery, to boot to it, shut the device down completely, plug in the USB and boot the device through holding vol up + power)
Sent from my LG-D855
The D850 never got any official OTAs that I'm aware of, but I'm on AndroidNow 1.6.
That's what I did initially, but this time I flashed it by removing Recovery. I'll try the LAF fastboot though.
Great work on this.....
Personally I am going to wait for a bumped version - just to make sure I don't screw something up when trying to flash this.....
On that note, have you tried to reach out to the bump team? Perhaps if you explain that you have a kernel waiting to be bumped, they might manually bump the image for you. I know they are trying to work out a method to automate this process, but they have the ability to manually bump stuff right now!
can we get a flashable zip of this please

We cannot get a flashable zip until team codefire gets the bump site up and can bump the kernel! The same thing that is holding up a slew of custom romz. This almost reminds me of a Geico commercial and a caveman being under a rock lol.
Deadly venom rom will posted soon. If you want to check it out when the link is up.

So I can flash this with flashify?
Until some sort of twrp zip is made?
I don't really understand the whole is it bump'd or not thing :-/

No, sorry, not yet, the problem is, there is a tool needed (not completely true though, it could be signed without the tool as well, but it'd need the fitting certificate, which has only team codefire) to sign not stock kernel images and make them flash and bootable, this tool is the bump tool, which is not released yet.
