Ehh I doubt it. Not really many changes between them... Least of all any that could possibly affect battery in any meaningful, negative way. *shrug* but who knows.
[Nexus 7 Android Development] Metallice:
I'm going to assume that you're implying that you are having boot hangs and not just curious. If stuck at the Google logo just hold power to turn it off and then hold it again to turn it back on.

If you are in a boot loop then that is most likely because, while the kernel is based on 4.2, the ram disk is not. I.e. it wont work on 4.2 until I update the kernel with a 4.2 ramdisk. Alpha 11's 4.2 kernel / 4.1 ramdisk works fine on 4.1 ROMs however.

Soon...
[Nexus 7 Android Development] Jay Aristide:
Very eagerly awaiting some M-Kernel goodness on 4.2 :)
[Nexus 7 Android Development] Triscuit:
I'm running a11 520 GPU, everything is silky smooth no issues. Thank you.

Congrats!!,

Well, my boot loop can wait. Take care!!!!

i sideload the official flash apk from adobe.com and it KINDA works... with Firefox, as usual.

as in, flash ads works, some anime videos works, ctv.ca videos works... but... ehm.... coitus stuff? just ads. no videos. said Firefox doesn't support the filetype.

gawddamnit.

on topic, grats on the exam n interview. i work in the healthcare industry and i can almost reassure you, there's no shame in starting in the 40s (7 yrs ago i started in the 30s), give it a few years in, it'll be more than tripled.

so dont worry about school and get crackin on that kernel! :D
[Nexus 7 Android Development] Metallice:
Haha exactly. Pretty much the only thing that hasn't gone html5 yet. Which is a interesting phenomenom in itself as porn has traditionally been one of the first to adopt new technologies and mediums. They play a large role in deciding which formats we end up using... VHS, betamax, HDDVD, Blu-ray ... you could even include adobe flash in there. But that's a whole 'nother discussion.

All in all when it comes to porn, my phone's 4.65 inches just doesn't cut it. You know what they say - if it's not on 7 inches, it's not worth doing.
[Nexus 7 Android Development] phonic:
Metallice - in one of your next kernels, can you possibly make it 3G compatible?
[Nexus 7 Android Development] Metallice:
Is it not already? It's based on the newest source with 3g support. If not I probably need to just check some options before building.
[Nexus 7 Android Development] phonic:
Oh, I didn't even try your latest one. I had assumed you would need to enable something special in order for it to work. I see that Google has a different image for 3G units (nagaskig) and thought that the kernel might be different. But if you think it's already enabled, I'll give it a whirl.
[Nexus 7 Android Development] Metallice:
Oh wait. a11 wouldn't boot on 4.2 anyway so you have no way of knowing haha.
[Nexus 7 Android Development] Jay Aristide:
Yeah, about that... what's up with some 4.2 ramdisk love? Or maybe just an anykernel.. I can live without init.d for a bit
[Nexus 7 Android Development] bpear96:
Metallice I put together a any kernel zip with your a11 zimage. Do you mind if I share it? Seems to be working great on 4.2 :)
[Nexus 7 Android Development] Jay Aristide:
Could you pm me a link to that, please :D
[Nexus 7 Android Development] Metallice:
Well, no luck when it comes to flash... Although I did figure out what was cuasing the graphics glitches on NFS:MW. The game bases it's graphics settings on your maximum CPU so with the increased clock speed to 1.6GHz, MW raises the graphics to a level that's apparently incompatible with tegra.

There are fixes available that will manually set the graphics to 1.3GHz mode, but you have to get those apks through the seedy back allies of android.

Oh and since I've given up on flash, I'll start compiling the new kernels. Should take a couple hours or so.

EDIT: Heh now playing NFS:MW in 512Mhz mode just for fun.
[Nexus 7 Android Development] Jay Aristide:
Now running m11 repacked with anykernel.. Missing init.d support and flash is messing with my porn sites again, but undervolting, over/underclocking, governor and scheduler settings all working right. OTG up and running, too.
[Nexus 7 Android Development] sahshah:
Do you use stick mount for otg ? Or is there any other way to mount USB?
[Nexus 7 Android Development] rebel1699:
If a12 is like a11, usb otg auto mounts on connect. Is otg+host mode charging still supported in a12 is the big question. Most likely is, since he did not state otherwise.

Ps- you got a free thanks. Hit wrong button, lol.

[Nexus 7 Android Development] Jay Aristide:
Flashed a12. Half my apps are gone, and I'm pretty sure I'm unrooted. I'll report more as I find it.

Okay, i'm still rooted, but root explorer, the pro key for apex, all my apex settings and customizations, guitar pro, sketchbook hd, great big war game, one more clock, player pro, both cut the ropes, final fantasy 3, horn, order and chaos, where's my perry, and several other games are not present. They're in tb with a line through them and no options but uninstal.

Everything is pristine on my wife's profile...

Ideas?

Edit: I'm on stock 4.2 by the way.
[Nexus 7 Android Development] veeman:
Flashed A12 on stock rooted 4.2. Everything works fine except for two things.

1. Flash still has the artifacts

2. Auto screen brightness causes flickering(sometimes) in certain lighting. (Wasn't there in stock)

Neither are a huge deal so I'm keeping A12.

Good to see the kernels continuing. Now I just need pa to release their 4.2

Same. I was wondering what happened to Bacon Reader Premium & Horn...

Update: reflashed stock kernel apps came back w/ data intact.
[Nexus 7 Android Development] ortrigger:
You could always use setCPU or Rom Toolbox to set a profile that changes your clock speed back down to 1.3 when using NFS MW.

OT: what area of Oklahoma are you from rebel? I used to live there.
[Nexus 7 Android Development] Metallice:
I guess there's something up with multi-user stuff. I haven't had an issue or noticed one before uploading as I don't use that feature.

Or maybe not. I dunno I have no issues... I'll see what I can do nonetheless.
[Nexus 7 Android Development] Jay Aristide:
I disassembled the stock 4.2 ramdisk, enabled init.d support in it, repacked it with a12 and used fastboot to flash the new boot.img. So I've got a12 working great with init.d support :)

Went to bed last night a11 was the latest kernel I wake up this morning and we're on a13 this guy is relentless.

Thanks man
[Nexus 7 Android Development] mobutu16:
Could u plz confirm USB stick is working?, not for me with a13+stock, a11+2.54 flawless, probably any emulated SD pending issue?.
[Nexus 7 Android Development] Metallice:
Maybe I messed something up permission-wise in my install script. I'll have to look. Then again nothin'gs changed with the alpha, and from what I've heard it doesn't have this issue.

I'm not going to add the stock kernel back. It was causing more problems because of user error than it was worth having. Truthfully if you want a backup of the stock kernel you can make one in recovery.
[Nexus 7 Android Development] Jay Aristide:
Is it a TWRP thing or have I been missing a key feature in CWM since I've started using it?
[Nexus 7 Android Development] Juzman:
The boot issue happened again. Had tablet turned off for about 2 hours. Turned it on and stuck at Google splash, rebooted into CWM and selected "reboot system" and booted fine.

Edit: Reboot from power menu is okay too. Just seems to affect cold boot.

CM10 Rom Dev

I'm making my first (feature filled, non-kitchen using) rom and would just like to check the best way to include this kernel in my rom. (I will of course have you in the credits and stuff :P )

Can i just extract the kernel folder from the zip and all of the system folder's contents into

~/android/system/out/target/product/grouper

Im building from CM source (for nexus 7), so hopefully i just paste the stuff in, sync+build and I'm good to flash my rom :confused:

edit: I'm dead set on including the kernel, not cause im lazy (not that im not) but for the practical side so that i could if i wanted in the future. It's also cause i'm learning. Thanks :P
[Nexus 7 Android Development] tobitronics:
Having this issue too. Resetting the device when stuck by holding power button solves the problem.

[Nexus 7 Android Development] Metallice:
Guys... I need to know what kernel you're on if your going to report an issue or bug.

EDIT: as in are you running the classic version or the new "plus" version alpha.

"running a 4.1.2 ROM/Kernel without a 4.1.1 causes you to miss out on many storage performance improvements and important, major bugfixes."

I don't get what it is meant here.. Does 4.1.2 depend on 4.1.1 binaries? Flashing a 4.1.2 ROM doesn't already include 4.1.1?
[Nexus 7 Android Development] O2Blevel:
I've been running the M-Kernel Plus alpha with stock ROM, without any problems. Running some benchmarks, videos, games, general stuff and all is good. Curious as to what features have been added to this kernel.

What is the LP core?
[Nexus 7 Android Development] Metallice:
,

Features? No "features" have been added or removed so far. There have been a few changes here and there, but not anything drastic other than the lp core clock change.

______________________________

LP core, LP cluster, Low-Power core, companion core, ninja core, stealth core, the "+1" in Nvidia's "4+1" architecture, or VSMP, Variable-SMP, Variable Symmetric MultiProcessing...

So I don't know if that answered your question or not, but I enjoyed listing all the different names for it haha. Nvidia needs to learn how to go with a name and stick with it. I know some of them are acronyms but still... gotta respect Apple in this regard. Not a chance in hell you'd ever hear them refer to it as the i5 or the Apple phone 5. Heck they even tried to do away with numbers with the "new" iPad... I'm looking at YOU Samsung. You're seriously going to refer to your phone as "the new Samsung", "the Galaxy S3", and "the GS3" all in the SAME COMMERCIAL? Brand recognition matters!... sorry for the rant.

If it didn't answer you question, googling some of these terms will.

Well I'm glad that the issue seems to only affect the classic builds, but it still doesn't explain why its happenning.... :(

I'd recommend running the alpha for now as it seems pretty stable. Although not really any impressions on how it compares but I would say its comparable.
[Nexus 7 Android Development] Juzman:
By alpha you mean the "plus" one yeah? I will give it a go. :)

Edit: Alpha is working fine. :)

Question? Running paranoidrom 2.2 and their kernel and running code in terminal tells me my ramdisk is not 4.1.2 what do I do? Do I flash provided stock w initd support then one of the kernels? I believe my ROM is cm10 based.

Thanks for any helpful input :)
[Nexus 7 Android Development] prestige777:
Flashing 4.1.2 binaries over 4.1.1 C@C 1.2.0 worked for me.
[Nexus 7 Android Development] Metallice:
Don't flash the stock kernel. You'll boot loop.

There's really nothing you can do. PA/CM10 hasn't updated their ramdisk/kernel from 4.1.1 even though the ROM has updated to 4.1.2.

The kernel will probably still work. Just flash it. PA/CM will update eventually.

I am using scrosler and I have none of those issues.
[Nexus 7 Android Development] Jay Aristide:
Running a13 now, and no issues to speak of so far, though I'm sure flash is still <expletive deleted>ed up.

I didn't pass out my copy of a12 because it would have run counter to Metallice's efforts, in case anybody was wondering. This thread only needs one 'official version' and one maintainer. If you start passing out 'here's how I hacked it together' stuff, things get cray cray
[Nexus 7 Android Development] sandnap:

What high quality audio tweak?
[Nexus 7 Android Development] Triscuit:
I'm installing the mod here: http://xdaforums.com/showthread.php?t=1889522 and it says to use a kernel with it enabled, and it gives a couple of kernels that have it.

[Nexus 7 Android Development] Triscuit:
Oops thanks, loving the kernel BTW nice and smooth. I'm getting a good 20-24 hour battery life.
[Nexus 7 Android Development] zlewe:
Requirements:

-Rooted.

-Custom recovery like CWM or TWRP.

-Jellybean 4.1.x Deodexed OR Odexed.

-Custom kernel with high quality audio tweak enabled is recommended (e.g. Franco or Trinity).

-Nandroid Backup, I implore people to have at least one recent one as this method is faster.

Compatible With :

-Nexus 7, Kindle Fire (reported), and Galaxy Nexus.

-Universal for all kernels and ROMs.

-All major players, including: Google Music, Noozy, PowerAMP (see note below), Apollo, PlayerPRO.

[Nexus 7 Android Development] vackraord:
Same here, also on stock 4.2.

CPU clock, voltage settings, changing governor all make the system unstable and lock up/reboot. Any logs I should check? I have tested clearing all settings for android tuner and reinstalled the app
[Nexus 7 Android Development] ortrigger:
Try a different cpu tuner app. I use setCPU and haven't had any problems at all.
[Nexus 7 Android Development] Metallice:
System tuner has always been a little iffy. It has caused me issues in the past. Then again it actually gets the voltage tables right unlike setcpu. I've been using TKT without issue. CM performance settings are usually fine, but we won't have those until CM10.1.

Trickster is the best app and definitely rivals all paid apps I have, and I bought them ALL to support the devs including tkt Franco glados and I'm sure that there are more. Thankfully most of the apps o bought for my gnex have active Dev participation for the nexus7 but if they didn't I would buy the apps again. What you all do for the community is worth more than a beer and I appreciate every second of time. Thanks for this kernel, just got my n7 Sunday, rooted Monday, flashing a13 wed morning!

[Nexus 7 Android Development] acidspider:
Can u please assist me in which a13 kernel to download? What is the difference between the 2 versions please?
[Nexus 7 Android Development] wizayne:
I believe that the difference is in the GPU clockspeeds, one being higher than the other and possibly something with the low power processing unit, but idk didn't read the entire first+second post, just the last 100 posts plus another thread by jay that sounded similar to lean tweaks for my gnex but again brand new to the n7 scene.

it sounds like both work on stock.. when in doubt have stock to reflash and backup. I'm taking the plunge right now

edit and please don't think I won't read the op I hate when people break things without reading and can't fix it, if that happens to Mr from my haste I will not make it anyone's problem by I do plan on finishing the read I just want to flash and sleep..
[Nexus 7 Android Development] sadde:
Hi

first of all ,thank you for your great kernel. We are blessed having you working on the n7.

A13 OTG-USB doesnt work - it mounts but empty folder , any solution to this?

I tried stickmount aswell , still no luck. Guess i have to wait until chainfire updates its app.

thanks
[Nexus 7 Android Development] Metallice:
The solution is on the ROM or App end of things.

(I believe) Kernel-wise everything is working as it should. Sorry :( Just have to wait until Stickmount is updated to support the new multi user mounting or a ROM does it natively (my money would be on Cyanogenmod)
[Nexus 7 Android Development] Metallice:
446/620 means the GPU is can scale up to 446MHz instead of 416MHz while 520/620 means the GPU can scale to 520MHz. More MHz means more graphics power at the cost of heat and battery. The 620 refers to the companion/low-power core which has been raised from 475MHz maximum to a maximum of 620MHz.

Hope that helps, despite its technical nature.
[Nexus 7 Android Development] sadde:
I have a apple magic mouse and i wanna use it with my tablet , but the actual gestures doesnt work. Can u please add the support into your next kernel update? that would be great:) thanks a lot

One question about voltages Mr. Metallice, im interested in undervolting.

Im using SetCPU, downclocked processor to 1100 mhz.

Which voltages are stil good for stable work.
[Nexus 7 Android Development] toidimaet:
I haven't undervolted this kernel but a 50-75 drop is easily achievable. (For my tablet, tolerances can vary) .

Saying that, in my experience undervolting has caused no discernable impact on battery life for me.

Better to get a good rom, an optimized kernel and leave it at that.

the screen backlight flick so bad A13
[Nexus 7 Android Development] jpar:
Hey guys, what are the default boot settings of this kernel for things like fsync, zram, lower backlight, cpu.. etc anything default you can think of.

I would liketo know because I would not like to mess with the cpu settings.

Thank you,
[Nexus 7 Android Development] Metallice:
Yeah its a 4.2 problem in general. You have this strangely specific and intermittent flickering on the stock 4.2 kernel. Turn off auto brightness to temporarily fix it. This suggests it's some bug with the 4.2 ROMs auto brightness.

If it is the 4.2 bug I'm referring to you'll be able to stop the flickering by just pulling the notification shade down. (Weird that this stops it as doing this does not change backlight level at all)
[Nexus 7 Android Development] bonzer2u:
Did you actually mean intermittent flickering on the 4.2 stock ROM instead of kernel? aka the a13 kernel on stock 4.2 ROM.....

Reason is that since Ive been running 4.2 stock, I havent seen this issue
