Thanks for attention, hope my efforts have become a catalyst to something great
The new discussion starts at; page 6
Great one!! Thank you very much, I hope this development will benefit all of us here
Have you tried using dhd.ko from CM9, or maybe even from Cowithgun's kernel? I also have no Idea, but I'm really interested in Kernel development. Too bad I haven't got enough time to try it :|
Sent from my Modded Stock DXLA2 (Didn't have the mood to update)
dhd.ko was compiled alongside with kernel, automatically.. the only problem is to use it properly
great job! did that kernel fix "can't turn on phone while off & charging"?

atm no, it's almost a copy of arco's kernel and not interesting at all, i'm just at the very beginning of a work, maybe sometimes later any1 finds something to solve it
I respect your work.Thanks for your contribution .
Hey dimaka! Good news that you starting to kernel development maybe in future you can add more governors like smartassv2 or sio i/o, or maybe you can overclock/undervolt it but yeah goodluck

guys, if you've seen any good guides to kernel modding, let me know..
seems like smartassv2 and lulzactive governors work..
still can't make wifi working..
google can't give me any links to i\o scheduler works, strange.. OC and UV are nice ideas, noted
changed toolchain compiler from google's prebuilts (source.android.com) to DooMLoRD's ones, seems it will be nice

About the Wifi being broken, i'm not sure but mind trying to see if this can fix it?
Sorry if i'm unhelpful since I got no skills at all when it comes to this stuff.

Honestly i'm more eager to get this working so there are better governors for the SGW rather than spending time and effort just to have USB hosting.

I'm just wondering is it possible to view the kernel of a similar Samsung phone that has more governors and use that layout as a base for the modded arco kernel?

moar teasers!
take a look on smartass governor
kernel is now empowered by linaro compiler
still waiting for some1 to help me resolve wifi issue
fixed smartassV2 problems, works nicely
also found the place to add i\o governors.. hm, the kernel has deadline, cfq, bfq, noop in sources.. strange, only bfq and noop are selectable in nofrills
have found sources of something like anticipatory.. searching further..
Wow can't wait this kernel released

Hi all,
Today I installed CWM and flashed franco's kernel for JB (the newest one). At first it seemed pretty fast so I was happy. I decided to install setcpu and set it to max 1,8 ghz with set on boot enabled (I know it was stupid, but I did not realize it at the time). After rebooting the phone froze and a purple layer appeared on top of my screen. Seconds later my phone rebooted. I set setcpu on 1,2 ghz max and let it stresstest for a couple of minutes. No errors were found. But now my phone lags sometimes, like if project butter just had disappeared and the normal android sluggishness has reappeared. Is this a kernelissue or did I damage my cpu with this stupid overclock? Btw, apart from the sluggishness in the animations I can run everything just fine.
I'm on Franco and have no problems. Why don't you try another kernel and let us know how it goes?

I understand people want to ask questions first, did you try to wipe and reflash?
At most I can probably assure you, you didn't damage your CPU.. there would probably be more dire issues if it was.
Did you flash a new kernel yet?

Not yet. Should I reflash franco or try another? Can I flash a new kernel over another kernel without wiping my whole device?

Yes, I've flashed 3-4 kernels on one ROM. You can dirty flash your ROM too or completely wipe and flash.
Either way its fine. I do suggest wiping and flashing though..

Setcpu is fine. In order to get stock, either use a new kernel or dirty flash.
Assuming.. if it was I'd guess the phone probably wouldn't be running?

You need to learn about what you're doing before you do it!
I flashed the trinity 1420-537 JB stable kernel, and everything works as smooth as it has to be. The strange thing is that it was a bit sluggish until I changed my wallpaper from a live to a normal one. Now I switched back and everything is still smooth :? . Anyway, does this kernel overclock the cpu itself or are the speeds in the name just the available range?

if I have such issues I will never flash an oc kernel to look if everthing is working. Install stock rom kernel back and try. If everything is fine......you can try an oc one.
On Trinity; first number is MAX CPU clock range you can chose and second number is fix GPU clock.....or just reading FAQ, Changelog etc. will answer your questions really quick

from what I've heard, some gnexs are really picky with roms and kernels. I guess your phone is one of them. I personally had problems with Trinity Kernel, since when I reboot, it sometimes bootloops for 5minutes and such. I personally had no problems with Franco though. In fact, I use Franco as my daily driver
Sent from my ASUS Transformer Pad TF300T using xda app-developers app
Franco's app let's you easily tweak the settings (overclock, change governors, etc.) which may help the sluggishness. I almost exclusively run Franco and his M5 is amazing!

A reflash might be the best option ... either the ROM or Kernel or Both lol thats my inner crack flasher talkin'
Never had problems with franco. It's trinity's kernel that made problems for me.
I run Franco's kernel myself. Just have to be careful with flashing the nightlies, it can be hit or miss. They are experimental.

This post only pertains to Jellytime Sosei/BakedBean 4.1.2 and is for users experiencing problems with their A100, yours may not. This thread is not to debate or argue about the kernels, please keep that in mind
Hey guys, I was originally testing these ROMs for pio, and constantly am changing or tweaking things on the ROM to find what suits our A100 best. Pio was building these blind, so he has no way to thoroughly test the ROMs and such things as build.prop mods/tweaks as well as kernels.
Let me start by saying this, I AM IN NO WAY BASHING ANY DEVELOPER FOR THEIR WORK. I AM IN NO WAY BLAMING OR STATING THAT ANY BUGS/FLAWS ARE A DIRECT RESULT OF THEIR WORK. THE THINGS I AM LISTING ARE ISSUES/PROBLEMS/BUGS THAT I HAVE OBSERVED OR ENCOUNTERED, AND ALL BUGS/FLAWS WERE TESTED AGAINST THEIR EQUAL. EXAMPLE, USING THE godmachine81/linuxsociety KERNEL, THAN REPRODUCING THE SAME ENVIRONMENT, I WOULD RUN THE STOCK KERNEL FOR TESTING AND VERIFYING THE ERROR.
Kernel Observation:SODsEveryone, including myself, tend to automatically flash linuxsociety's GodMachine kernel v2.0, as it really is our only option for JellyBean/CM10/AOSP based ROMs. We do have ezTerry's kernel, but it has not "supposedly" been tweaked for 4.1.x systems. Although it is the base for GodMachine kernels. I've never used ezTerry's kernel,but I may test it like I've been testing GodMachine.
Anyways, for this ROM, I have found that the godmachine kernel performs poorly on Sosei ROM. With GodMachine kernel, I had tons of issues with constant BSOD/SOD. (Sleep of Death) The SODs were worse if you left wireless on, and the SODs were completely random, no matter what I did, if the tablet fell aslepp, it SOD'd on me. Using the stock kernel pio packed with the ROM, resolved much of this issue for me. The only time I have SOD on the stock kernel is when Wifi was left on, and the chances of this happening were 99% LESS LIKELY compared to GodMachine. You can combat this, by sacrificing battery life and using an app that's free on the playstore, WakeLock. If you choose to go this route, the "Partial_Wake_Lock" option consumes the least amount of battery while still preventing SOD. None of the 3 options for forcing wireless to stay on worked for stopping SOD.
RANDOM REBOOTS/CRASHING/FREEZINGI myself did not have many issues with random reboots, but I did have some issues with random app "force closes" and freezing to the point where you'd have the almost force close I call it, where you get an option to close or wait for the app. I have not had this issue using the stock kernel, unless related to the next topic...
GPU/VIDEO INSTABILITY/ODDITIESI, as well as a few others, have reported issues with display. Most users have noticed an issue with flashing lines, tearing, and artifacts on the desktop. I have also had issues when play a THD/HD game, for example Modern Combat 3: Fallen Nation HD, where anytime after about 20-30min, the display would become compltely distored, almost like when you were trying to pick up a TV station using rabbit ear antennas, and the game crashes/freezes, but you do not get an option to force close, so you have to use the Navigation bar HOME button to get yourself out of it, than you need to kill the game anyway you want, but if you don't kill it, it will load you back to that distorted, frozen image.
In the GodMachine kernel, the GPU is overclocked as well as being able to overclock your CPU, but you cannot adjust the GPU yourself with any application. Linuxsociety states: "Stable GPU Overclock @ 450mhz (scales from 300 - 450)"
I do not have these issues with video when using the stock kernel, nor do I notice any lack of GPU performance with lack of GPU overclocking.
In my honest opinion, I STRONGLY RECOMMEND the STOCK KERNEL. Yes it is lacking in some features, but it is capable of being overclocked as well if your interested in doing so. Using the interactive governor provides the smoothest performance and still retains some battery savings. Conservative, OnDemand, userspace, and Performance are offered as well. The I/O Scheduler only has NOOP available, but if you do some reading, NOOP is actually recommended for Flash Devices, like ours.
To get back to pio's stock kernel, you can boot into recovery, wipe cache and dalvik, and dirty flash the ROM.
BUILD.PROP EDITINGI cannot even begin to tell you the amount of hours I invested in testing and editing the build.prop to obtain what I find to be the most stable while still possibly enhancing performance/responsiveness and battery life. I will link you to my FINAL build.prop mod for you to download if you'd like. In all reality this consisted of just commenting out several lines in the original build.prop that our A100 did not like. This will also fix issues with the video camera recording if you have them, as well as improve certain app and system performance and functions. I've also had more reliability and just odd **** happen when I use the TCP/IP buffer enhancement code lines so those have been commented out as well to keep WiFi stable. I really see no performance gains with them other than SpeedTest and there is a reason, I am a Networking IT Student, and don't feel like explaining that now in this thread. lol
Download build.prop.sosei__tweaked
Using a FileExplorer with ROOT LEVEL ACCESS (I recommend ESFileExplorer),
Copy build.prop.sosei__tweaked into the /system folder
Rename current build.prop to build.prop.bak
Rename build.prop.sosei__tweaked to build.prop
Reboot into recovery (TWRP or CWM) and wipe dalvik cache & cache, reboot
make sure you wait ten, reboot and wait 5-10 before you start using your tablet
This is all in my observed, hands-on testing and experience, and everyone's results will vary based upon factors such as user setup, apps install, the way a user even uses their tablet etc
I hope this might help/inform some of you guys.
Very nice, thanks for taking the time to put this together for the users. How did that kernel I built for you do?

G2x-temasek CM7 Nightly 11/18/12 Build, Trinity ELP Kernel
I'm using/testing this rom along with gm's kernel. I have not had wake SOD issue. It sometime takes a couple if clicks on the power button for it to wake, not sure if this is the issue you're referring to as SOD. Everything seems to work great so far. Netflix, audio, headphone all work well. I have always wanted some aokp flavor on this tab, and now that wish is granted thanks to the awesome work of pio, bb devs and gm.

No, I had sod constantly. But not slow wake up. I get slow wake sometimes on stock, but atleast it will wake.
Everyone's tablet is not the same, some hate the GM kernel.
Mine seems to be one of those, but had I known how smooth and stable the stock kernel was, I prob would have stopped using GM awhile ago, I've had nothing but issues with it, if you've seen any of my old posts over last couple of months.
G2x-temasek CM7 Nightly 11/18/12 Build, Trinity ELP Kernel
Other than a couple of SOD's I haven't had any other issues with the gm kernel. I have since bumped up the minimum speed to 312 Mhz and that has seemed to fix the SOD issue but I still need more time to conclude that. I'm also getting some impressive quadrant scores with it too (3046) and that's with a fully loaded non-tweaked system. The only reason I like the gm kernel is the variety of I/O schedulers and governors...there is absolutely nothing wrong with the stock kernel. I'm still very happy with the JB ROM, I have it set up almost identical to my Samsung Nexus phone which makes it very convenient.
GM SOD Issue Resolved ( For Me)
I can now safely say after 4 days of testing that raising my minimum speed in the GM kernel to 312 Mhz has completely eliminated the SOD issues. I know that every device acts differently but this is working on mine!

I didn't want to do that myself and lose the extra battery juice.
The point is it should be able to UC down to 216 and hold there with no issues.
The stock kernel does it perfectly well with no ill effects.
I have a modified Godmachine kernel that is unreleased and I will be testing it soon.

SoD is just a failure to resume from sleep, reset button or hold power will reset it to normal. Some tegra2 devices have it, some don't, even among the same series, like a100s. The best way to combat it is to not sleep, but of course battery sucks.

I can understand not wanting to lose the extra battery juice, lots of what we do is to extend it. I did however undervolt the 315 slot to the same as the 216 (750 mV) so there's no addition battery drain. It's a win-win situation! Let us know how the unreleased version works out, I'm always looking for options.

G2x-CM7 Nightly 11/18/12 Build, Trinity ELP Kernel
..
I could use some helpful advice. No matter what kernel I switch to I get quite a few reboots. I am no expert. It gets kind of annoying. I do not overclock and have checked out the different GPU? (384,512) options that are out there. For some of the governors i check for the MAX_speed to be the same as the slider in the apps. If you could, it would be cool if @ anyone to give some feedback or if there is more information needed. GSM nexus/CM10 / trinity franco faux glados
EDIT- I think a battery overheat or sometimes the cpus run over or at max or if there is such a thing as overload?
I guess there must be other threads like this or posts. What exactly should be put in the search box? I'm not as smart as the rest of you.
Check the stickied post in galaxy nexus general section. MBQ's post has a lot of info
I'm currently running PA 3.6 and the AK Diamond kernel. 99% of the time, everything works fine, however when I start running Puzzle & Dragons, the phone gets really hot and more often than not will reboot before I finish playing. I have also tried using the AK Kubo (stable) kernel, and it does the same. I'm kind of a noob so I don't tweak the kernel settings very much, and I don't really know how to go about fixing this. One thing to note is that on the stock PA 3.6 kernel the phone still gets really hot but it won't reboot. I'd like to keep using the AK kernel as it makes my phone run really smoothly but I would also like to try and fix this problem.
The sole common point to that whole story is Puzzle and Dragons.

Are you saying that AK kernel and P&D just don't get along? Because although it gets hot, on PA 3.6 with its stock kernel it won't forcibly reboot my phone like it does with AK. I've found a temporary workaround which is to switch the governor to powersave while playing...but that doesn't really fix the issue...

there's this thing called quality of the components used; the chinese can make the best and the worst.
every chip handles the tasks that are required of them yes, but that's why you see devices that can OC to 1.6, 1.7 even 1.8ghz stable, or UV like a boss, and others that can't handle even 1.6ghz oc or huge UVs.
for example, mine can UV like a boss, but not so good at OC'ing.
thermal throttling of the cpu might be more agressive with some kernels.
