[MOD] BlaY0's kernel 2.6.29 with UTF-8 NLS support + additional modules

Hi,
I decided to post here two kernel updates I mainly use or have used on my Legend. They are nothing special (not overclocked), with several additions and changes, just something I want to share with the Legend scene. They corespond to two different (stock) extraversions:
2.6.29-5f084974
Based on stock HTC kernel version 13be9c9c available from their Developer Center. The kernel is perflocked by default (123-246 MHz screen OFF , 246-600 MHz screen ON, 123-600 MHz scaling for ondemand governor). Modules (drivers) included:
aufs.ko (overlay file system driver)
cifs.ko (CIFS file system driver)
cpufreq_conservative.ko (conservative scaling governor)
cpufreq_interactive.ko (interactive scaling governor)
cpufreq_powersave.ko (powersave scaling governor)
lzo_compress.ko (lzo compressor)
lzo_decompress.ko (lzo decompressor)
perflock_disable.ko (forcibly disables perflock)
ramzswap.ko (Compcache driver)
sdio.ko (TI SDIO driver)
squashfs.ko (SQUASHFS 4 file system driver)
tiwlan_drv.ko (TI Wlan driver)
tun.ko (TUN/TAP driver)
ext4.ko (ext4 file system driver)
jbd2.ko (ext4 dependency)
lockd.ko (NFS)
nfs.ko (NFS)
sunrpc.ko (NFS)
2.6.29-8d705e0d
Based on CM's 2.6.29.6 GIT with some additions from Alex's GIT. Specs are the same as for above version.
UTF-8
As an option, I also prepared two kernels same as above but with UTF-8 NLS support set as default.
Installation
Just flash the update via ClockworkMod... it will run over your previous kernel and modules.
Note
These kernels are ment for those using stock based ROMs (like chefs using stock ROMs as a base) and are missing support for things mentioned above (nfs, aufs, cifs, tun, interactive governor...). Those using CM based ROMs don't need any of these... CM already has kernel with all support mentioned above.
Warning!!!
Please read the whole post before you download (it's really not so long)! Do not apply these updates if you don't know what they actually do!

Hello,
this one : 2.6.29-8d705e0d doesn't work with Azure Nightly 8.
The touch screen don't work !

Build 8 quite bogus, random reboots and non working TTS
have you tried with build 7?

I have similar problem with Azure Nightly 7 and Kernel 2.6.29-8d705e0d
Touch screen don't work !

Probably I should've mentioned that these kernels have been primarily ment for stock based ROMs.
I don't get it guys... I believe I mentioned in 1st post that second kernel is based on CM's so why would one ever want to us my kernel with CM... CM already has the right kernel with all the modules and statically built support for anything I mentioned above.
If you guys are trying nightlies expect problems but most important learn how to debug them. If you just write that it doesn't work, you basically did nothing to help solving the problem or improving things.
One more thing... did you guys try dumfaq's OC kernels with those CM nightlies?

With Azure Nightly 7 the phone starts correctly, I can not use the touch screen (it's impossible to navigate with my fingers )
And no I don't try dumfaq's OC kernels with cyano nightlies.

I would like to say something:
If you don't have any idea what these kernels actually change, then don't use them. There's no point in going "Duuh, BlaYo made a kernel, it must be awesome! I'll use it", when you don't know the advantages of using them. This kind of thing goes for a lot of stuff on these forums. If you don't understand what it does, or if you wouldn't know where to start with debugging errors, then either don't use it, or do research and make an informed decision on whether you actually need it.
And this goes for yez nightly users, too: nightly builds are almost never better than the stable. If you want CM, use Azure, not the nightlies. Unless of course your doing real testing, debugging and then feeding it back to CM developers.

Exactly!

Request: nls_utf8 module please.
Hello BlaY0, Thank you for you posting the kernel.
I am enjoying cifs with your 2.6.29-5f084974 on Azure, thank you!
Would you please add one more module "nls_utf8"? This helps converting filenames written in lot of languages other than English.

That can be arranged. But I have a question for you. What's keeping you from compiling it yourself? Since you know what those modules are for, I'd suspect you have done it before... at least for x86 architecture?

Thank you for your reply!
I am sorry, I've not tried it yet, only read FAQ #2 in "CifsManager" created by f3d0r.
forum.xda-developers.com/showthread.php?t=756158
Q: I mounted my favorite share successfully but files with special characters are not displayed correctly.
A: Try to use a kernel with explicit UTF-8 support or try to find/load the kernel module nls_utf8.ko via a simple init script.
Click to expand...
Click to collapse
May I try it with your help?

Hi BlaY0, please hold my request.
I found your message at "[Q] Custom Kernel" thread. I will try by myself with kyosa's config. Thank you!

Check this one too...

I added nfs support to 1st one and ext4 to both. I also prepared optional kernels (same versions) with UTF-8 NLS support set as default.

My two cents:
For a few of these it doesn't really make sense to compile them as modules. tun, lzo, utf_nls don't really bloat the kernel or negatively affect performance for example.

I know... I just put them here because you can freely extract them and use them with plain (not modified) stock kernel. That's why I'm using stock kernel extraversions and not my own.
As for NLS it is already statically compiled (not as modules) in those two kernels...

Hi BlaYo, Thank you for your new kernels! "5f084974" kernel and modules worked perfectly with Azure1.01! I can now read any filenames on my file server. I am so happy!!
Ah-- Yes, last weekend I gave up. I could not make wifi active...
(Of course, I re-compiled tiwlan_drv.ko) So I gratefully accept your favor.
Hello Ali ba!! Thank you, I found "nls_utf8" was already enabled in your nightly build. (I saw in config.gz) I am sorry I've not test them yet. I will test and report about this!

vorkKernel-OC/UV Kernel for CM[20111105]

Hi. The following kernel is presented to you by
vorkKernel Team:
- kiljacken
- Benee​
Click to expand...
Click to collapse
This kernel is for Cyanogenmod and Miui. *Could* be incompatible with latest kangs or nightlies (after a kernel update from CM team). No support for stock or mcr...
It's incompatible with MIUI and CM Builds before #177
New vorkKernel Twitter Bot: Here
First I want to make clear that all credit goes to aremcee/arcee/rmcc (man so many nicks ). He did an awesome job with the kernel.
I just tweaked it a little bit to my needs.
Features:
uv/oc support. OC up to 1,5GHz (With E-Peen version)
AVP/System/RAM/GPU OC with E-Peen version
1,2 Ghz for batt safe version.
Special tweaked (working!) Performance and Powersave Govenors which don't lock the freq to one level (they choose between 3-4 Freq steps)
It's even possible to set max/min clock via setcpu or CMSettings!
Voodoo sound. Thanks supercurio! So awesome
Default IO-Sched is Deadline with a special flash storage tweak
Slub allocator
tweaked CFS cpu sched (Low latency)
compiled with a tweaked toolchain (base linaro gcc - optimized for tegra2)
VFP optimizations (vfpv3-d16) and overall compiler optimizations
flags! (more below in the flag section)
A App for easy downloading and configuring. Credits to kiljacken!
Click to expand...
Click to collapse
The standard part:
I'm not responsible for melted phones or something like that...
The camera is unstable with E-Peen mode (due to AVP OC). After a reboot it needs to stabilize a few minutes (so you break it with every reboot again). Same for Bluetooth. Please don't report a problem regarding this. It's known and can't be fixed.​
Click to expand...
Click to collapse
And the source code here.
Download (Market)
Credits to kiljacken for this awesome app! You need OI File Manager for the app (Comes with CM)!
(and if you refuse to use the app - or the app is refusing to work with you: here)
Only change something, if you want to enable OC - No need to touch anything else (like govenors, schedulers)​
What are flags and how can I use them?
I recommend to use the App kiljacken made, because it's super easy for you guys. If you not want to use the app *sadpanda* then you can click this link. This is the file the app is fetching to generate the UI.
The layout is following:
Available for following device/Element style (more below)/the flag you need to add/Flag name in App/Description for general Flag/Choice name in app/actual value you need to add after flag name
If the last two points are added you first enter the flag name and than the value. For example: density230
You connect the flags with a: -
Example: -camera-ring ...
The script is configured to detect flags after vorkKernel-VERSIONNUMBER. So you can add some flags after this.
Element style
c = Checkbox
l = List you can choose things from
e = you can enter your own value​

Error Reporting Guide
Start with rebooting, if that doesn't help, reflash CM and then the kernel, and check again. If you're using the updater app (make sure you have the latest version), use the error report function (and describe what you're problem is). If you're not using the app, then post what flags you are using, along with what your problem is.​

Additionally I just want to point out that I'm not doing this as a fulltime job, so don't expect daily updates or something like that. I will try to fix a problem as fast as possible but in some cases it can take a while.
If you want to support me you can sign up on dropbox via my referral link or just push this nice thanks button .. If you want to donate you can donate to aremcee/arcee/rmcc something. I'm learning C and linux and vorkKernel is my learning project and it is a hobby for me. Anyway if you still want to support a poor student, I have a link in my signature

and a very big thanks to b3ndech0 for his buildbox.

Thanks, this is very much appreciated

This kernel is amazing! Nice work with the filename flags. It's brilliant! This way we don't have to have the same setup, but can enjoy both CM7 and the kernel.

I'll try this kernel later. Will wait for CM7 getting more optimized for our devices first. 2000 Quadrant scores out of the box just don't cut it - I don't want to overclock to 1.4 GHz just to reach speeds of MCR FR14 ;-)

More things will be in it soon. And Quadrant doesn't matter. CM feels better in normal use (except a few problems but it is a really good starting point).

Yes I know it doesn't really matter. Although, generally speaking, higher scores means the software is more optimized to the hardware; framework, kernel and/or drivers.
CM7 should be able to smash the performance out of the LG stock ROM without problem...
Thanks for you kernel additions! Subscribed to this thread now so I can follow your progress.

is this kernel for a stock rom?
thanks

Nah. You can boost quadrant to oblivion via data2ext for example on desire/nexus but it didn't helped in real life performance. The sql sync disable doesn't help with real usage, but boost quadrant etc. So many things which doesn't improve real usage, boost quadrant. Like deleting your /system (pro move...).
But yeah in some parts you are right and optimizing drivers boost it too + help real use performance, so I will do this too.

Yep but this would break pimp my cpu support and I think pimp my cpu is the better deal. A easy user interface with undervolting support. Awesome! .. so no I won't add it to cm settings

Awesome OC in CM7 makes it even better

I know I'm going to get flamed for this but how do you o/c once you have flashed the kernel? when i open setCPU its already at the max 1g when i go to the CM settings there's no frequencies to select in the cpu management option
is it different on the tegra chips as opposed to qualacom?

Ok if I understand the changelog from kholk correct, most of the changes are already included (don't know exactly because he didn't copied the commit names and sums the function up). One commit isn't in it because it introduced the graphic glitches. vfp3-d16 support and compiler optimization will be added with next update. Then most things are in it.

Nah no flaming . You need pimp my cpu for it. Cpasjute did some kernel hacks to enable oc and add a uv function. That means you can undervolt without compiling the kernel again. Unfortunatly it isn't compatible with setcpu..

The kernel seems ok; I tried OC till 1200 with 50-100 UV (depending on OC).
What's very good with CM7 (and this kernel) is battery life, 30-40% more compared with Modaco ROM (till FR14).
Anybody have tried higher frequencies (1300-1400)?
Thanks a lot.

[KERNEL][ALPHA] kernel 3.0.8 ODM/NVRM tegra forward porting

Since I had no permission to post a new thread, so Ive just posted a reply at the following link
from http://forum.xda-developers.com/showpost.php?p=23783120&postcount=1338
wkpark said:
This is forward ported tegra kernel 3.0.8 based on the Nvidia's ODM/NVRM tegra kernel 2.6.32.9
http://github.com/wkpark/tegra-linux-3.0.y
about ~700 commits are cherry-picked from the tegra kernel 2.6.32
almost all commits/commit logs are preserved. some commits are not needed anymore and some commits hard to merge.
anyway this is the result of my effort.
0. prepare android-common repo. it contain's minimal changes for android. the latest mach-tegra tree is removed.
1. about 4~6 hours needed to cherry-pick quick and dirty manually. I can figure out where are the hard parts.
2. fix to make it compile
* add slab.h / remove smp_lock.h / fix .unlocked_ioctl / fix DECLARE_MUTEX etc.
3. apply SU660 patch sets. fix for kernel 3.0.x
4. first try to boot => fail~ :>
5. figure out where are the trouble making points
* timer / irq / gpio / platsmp codes are changed in the kernel 3.0 => dig the log and fix it up
6. at last I can make boot su660 up! (about ~15 days needed to fix to boot up. total 300~400 times retry to boot)
----
the uploaded git repo is rebased interactively (remove some useless history, merge some hunks etc)
and I separate it into three branches
1. tegra-orig-3.0.8 = original android-common + tegra 2.6.32 patch series
- can be used the base of all other nvrm/odm based tegra kernel.
2. su660-lg-usb = tegra-orig-3.0.8 + su660 patches + lg-usb for official firmwares
3. su660-ics = tegra-orig-3.0.8 + su660 patch + ICS touchscreen patch, camera patch by rmcc
currently it works nicely with the SU660

- simplified platsmp.c (some parts of platsmp.c already included into the core code)
2. revert some part to original ramdisk.
- emmc/sdcard swap fix (for testing purpose)
- USB vendor ID fix included (for USB tethering)
3. included YAFFS (by vadonka with minor fix)

3. [HACK] copy the warmboot information to the original reserved_buffer
area before shutdown.
03/28
1. star: fixup some minor bugs (various compiler warnings are fixed)
03/29 (http://forum.xda-developers.com/showpost.php?p=24181934&postcount=258)
1. star: add CONFIG_STAR_BATTERY_UNIT_UV to support voltage unit in uV
2. su660: adjust star_capacity_from_voltage_via_calculate()
- i think it is not su660 specifc. so Ive just applied it onto the P99x
- use star_capacity_from_voltage_via_calculate() to adjust battery capacity after singular 3G/BB/rild behavior to fix "999%" battery bug.

Most is already working. Just wifi is the big problem with this kernel but I think this will be soon fixed cause we have good developers on our side.

Very nice work! man!

works well for a first test, just had one total lockup so far, but who knows if it was even related to the kernel.
i do notice that switching between tasks seems a bit less responsive, even though 2d performance indeed seems a bit smoother.
very good for a first release! hope other devs will join in here soon

If that wasn't your question and you actually want to change it, the file is located in \system\etc\vold.fstab and you can edit it with a text editor. Just swap the two lines around. (Aka, point at different targets. Any sensible person could work it out )

I checked this already, nothing changed there! Must be sth. else. Damned I want to use this kernel but all my stuff is on the externel SD card

First, you can install the kernel again. But wipe dalvik cache.
Hope this fix it.

Yes! Very good job indeed!
Very fluid, no wireless problem here, sdcard mounted as usual, I will keep it for a while..
Many thanks! Impressive job.

[KERNEL][STOCK] KosiKernel 006 (build 20120605)

Since I've been asked several several times now to release the kernel I'm running on my own phone I took some hours and prepared it (clean build, cleanup of commit comments, etc.).
Beware that this kernel is build for my own purpose and usage-pattern so it may or may not work well for you. I have a pretty tight schedule with a full time job and also working on my master thesis therefore I cannot guarantee any support for this. That's also the reason why I keep this short and simple. Nevertheless if you try it please report some feedback on your experience. Don't let the version 006 irritate you, this is the first publicly available version.
Big thanks go to all developers who made this possible in the first place: spica1234, StefanGünthör, vadonka, and all others who provide the current sources of their kernels

Installation
As usual install ZIP through CWM after performing the obligatory backup. Wipe of dalvik-cace and cache partition recommended.
Can also be combined with spicas Performance Packs for additional performance.
If instabilities arise, try increasing voltage by +25mV (worked on my phone).

wish you the best of luck sir, new dev are always welcome

Thanks man, my wish came through, thanks for sharing and good luck mate

Yes there my man comes!
Kosi bro felt very gr8 seeing your kernel. Congrets.
And thank you for giving TRUE honour by using SR3R as base sources with revolutionary OTF. I really feel good that atleast my SR3R sources are belived to be usefull, as Today i can see almost all stock kernels being either fully/partially based on performant SR3R sources. That's a great matter of HONOUR and PLEASURE to me. Thanking you to using it.
BTW you are free to ship Official OTF HP 2X OTF Tweaker Application with your build. I preffer newer Myrt OTF so you can use both but from my side you're free to use any of my work without my permission
I'm eager to flash. To be very frank I found your kernel building tutorials very easy for newbies. Keep updating that thread also, with new tips for newbies.
Once again congrets and keep releasing newer kernels, if you cant manage time then atleast once in a 10-15 days

How nice, also to see yet another Austrian flag on top of a kernel developer thread

Would it be correct to say WiFi instabilities cannot be fixed until LG releases an updated driver?

First impression coming from Spica1234 sr2r2 kernel my first notice is reduced smoothness, but it's also well known that sr2 had great smoothness. Anyways it seems to run fine and stable so once again thanks for sharing

I'm not sure. I integrated some fixes from NVidia directly and tried out some other changes (CONFIG_DEEPSLEEP => only "hibernating" WiFi driver on disable, not completely unloading kernel module). The deepsleep made no change in the short run and locked up in the long run so I deactivated it again. The NVidia patches made it a tad more stable (at least that's my impression) but it's still far from rock-solid.
There are however several other options which are still on my todo list:
check and try bcm4239 driver from CM
check and try bcm4239 experimental driver from Stefan Günthörs repository
check and try bcm4239 driver from NVidia/Broadcom repository (which lacks the LG adaptions and is therefore much more work)
look for other possible sources of updated/changed bcm4239 driver on Tegra boards
check individual commits and fixes in all repositories and integrate/merge/port the sane and safe ones
So there is still some work possible on my side but the possible outcome of each single option is still unknown.
IF, however, LG would make another update to the WiFi driver publicly available this would surely be another highly relevant try/source to have a look on.

Thank you. Glad to know I am not the only one bothered by WiFi problems. I have tried many ROM/kernel combinations and it's the same story everytime: At first it works as it should, then speed begins to drop, then it refuses to be turned on or off, causing a crash. I think I will give the v20s a try.

Tried rebuilt v20s for a few days. Sadly the slowdown is still there, but the driver seems a bit more resilient -- I haven't got any errors when turning it on and off.

If you want to test the standard 2x features you'd better to flash the original lg rom distributed in your country, baseband included. After mobile update do a factory reset. If you have problems contact the local lg support. If everyting is ok and want to waste time, try custom rom/kernel. Then all the problems will be between you and xda forum.

Mourta Kernel, the continuation of IODAK's excellent work.

Featuring a new cpufreq interface, AbyssplugV2, intelliplug and a whole host of new additions that are not available in any other kernel for the x3.
Among them are updates only found in this kernel, saner defaults via config, better optimizations for the actual code and a rewritten version of devfreq.
It also have an updated baseband configuration and built in rather than to keep a module as it makes no sense to have a vital function as a module.
https://bitbucket.org/mourta/liquid_kernel_lge_p880-stable/
Kernel: http://www.mediafire.com/download/viy5a3dtaccd0gm/mourta-stable-08-23.zip
If there is a request for it i also have a ROM available based on grouper blobs, AD optimizations and a build around this kernel with a new dev tree.
For kernel install, it's anykernel, you can install it on any custom ROM, for stock and the lastest updates you will have to head over to Modaco and my original thread.
Note that this is a one time release, if you like it you'll have to head over to modaco to get updates.
it should be noted that the recommended settings is using intelliplug (you may need to use kernel tweaker or trickster mod for that if you're not running my ROM, and abyssplugv2, i also recommend ROW for a sheduler and Westwood for your congestion handling.
Note that you can now overclock to any frequency and it will feed the GPU chip with the needed volatage, this is great for cooking a roast beef but not for any practical use.
Quadrant scores are 8k and the last Antutu was at 16487, no overclocking but you won't reach that without using my ROM.
And with that... i'm done.
Thanks to the IODAK, Fransico, Adam77Root, Faux123 and others that provided code and/or input.

Oh, what I see here? The awesome kernel I'm testing with @ottomanhero and lucaarx and the great dev and friend @IcanhasLG coming back on xda? Let's rock hard&heavy, right now!

We'll see how this goes.
Thankfully i am in touch with a mod that will keep this drama free,
And for anyone wondering, peppethustra is head of my testing crew, you get stable releases because of them.
It should be noted that i'm still going to prefer the forum that greeted me over the one that shunned me from the get go, updates here will be sporadic at best but on time on the other forum.

It's great to see your work on XDA.Now everyone can experience your awesome work
P.S. you can find neccessary links in my signature

Great work, running your kernel now.
But Iodak was not updated since long ago and its sources does not contain many great fixes from cm11 kernel.
Thats why Demetris relased Cyodak kernel in Android development section. It's Iodak brought up to date with latest cm 11 kernel .
It would great to see Muorta Kernel based on Cyodak instead of old Iodak. We would have your exclusive features with up to date cm11 kernel upgrades. But maybe you already upgraded iodak's source, let us know

Obviously, the real necessary updated patches have been implemented yet ("continuation" means this, too), so it's not necessary nor in Mourta's plans to base it on cyodak (which really isn't the only way to find updated code for our device)

Outdated sources never are a good base for developing a fresh new kernel or ROM, if there is a new compatible code implementation ready to be merged into the code That's the first thing a good developer checks (and if you can, look at Mourta's bitbucket linked in the OP to view his commits, there will be all the principal news about new code implementations)

Go to Modaco and find newer version (26/8/2014) . It will resolve problems like yours

Okay will do.

How's the deep sleep ?

this version, according to trickster mod, does not use deep sleep state and still screen won't wake up sometimes. so i dropped it for now.

Can you give more info about your ROM, kernel settings, setup etc. and provide a logcat if possible? That's a rare issue you're having there.I've used my phone for 20 hours now, (%3 battery left) and it slept for about 15 hours, same version.
I suggest you to try flashing the kernel twice.I had such problems with iodak kernel back in the time and flashing it twice had fixed the deep sleep issue.

@peter_altherr And more important thing: have you at least wiped cache and dalvik before flashing the kernel? If yes, try wiping system partition too (no factory reset, you can leave /data partiton intact) then reflash ROM, gapps and kernel, and see how it goes..wait 3 or 4 minutes before trying to wake up device, after the first boot, and deep sleep would start without problems

I have tried the 26/8 version but that still gives me RIL problems, I get no signal whatsoever. I cannot grab a logcat as I need my phone to work right now but I'm Running latest beanstalk version.

Wait for next version, great changes will come even about this issue

@peter_altherr you should unplug it from charger and try unplugged.
when charging cpu never reaching deepsleep.

@ whoever had freeze/sod problems with last kernel version: a new fixed release has been uploaded (it's a minor release: reverted GPU OC, which was causing the problem). Check official thread for the download link

my phone does not see SD card with 0902
and yes im 100% sure its kernel problem....recovery sees my sd, and so iodak kernel
