Will this kernel work on android 4.3 beanstalk ROM??

Please Don't Forget To Press The Thanks Button!! :D :thumbup:
[Nexus 7 Android Development] thereal_bigjake:
I use it with BeanStalk
[Nexus 7 Android Development] adi160699:
Thank you for the reply I'll try the kernel!
[Nexus 7 Android Development] paul20:
hi,

i would like to know if your kernel includes usb modem drivers because ppp_widget can't find my toggle
[Nexus 7 Android Development] thereal_bigjake:
I have never used one but I read in the op there is a ppp_async module you can use. Is that what you mean?
[Nexus 7 Android Development] paul20:
i have insmod the module but i have some issues
[Nexus 7 Android Development] Tipkaros:
I've noticed that changing TCP to "reno" gives much better performance on my tab with PA or PA SaberMod.
[Nexus 7 Android Development] CreepyE:
Care to elaborate?
[Nexus 7 Android Development] jfmcbrayer:
Is anyone else trying out the smartassv2 governor? If so, do you see it pegging all four cores at max (or 1 step below max)?
[Nexus 7 Android Development] sgt. meow:
The smartass issue is known. We're working on it.
[Nexus 7 Android Development] jfmcbrayer:
Excellent, thank you. Looking around, I see that it's affected kernels on other devices as well.
[Nexus 7 Android Development] rhg135:
I don't even know how you debug a kernel, but my hunch is to look at the ramp up code and add printk

Also I heard the new carbon nightlies don't work with custom ramdisks, so http://teamgelato.com/rhg135/n7/carbon/oxydo-20131024.zip

EDIT: due to someone trying this on a non-cm-10.2 rom, don't.
[Nexus 7 Android Development] sgt. meow:
I was thinking of the ideal freq. According to the documentation it aims for the ideal freq. For some reason it's shooting past that. Time to sprinkle some printk's.
[Nexus 7 Android Development] jfmcbrayer:
My initial feeling is that it's ramping up correctly -- it doesn't jump to the highest frequency immediately -- but that eventually (and this may be fairly quick, especially if sleep_wakeup_freq is high), every core will climb to the top eventually. And then it's not coming down when it should.
[Nexus 7 Android Development] sgt. meow:
I think the zImage base is causing some problems for me. The last one didn't boot properly.

So boot.img's for the next few releases before I figure out if it was a code issue or a ramdisk issue.

Stay tuned.

Regarding the USB DAC bit, something's keeping the guys at the other end busy, so we'll just have to wait. To be pretty honest, I don't know myself if it will work with the newer patches as I haven't seen 4.3 kernel with working USB DAC so far. :(
[Nexus 7 Android Development] miki67:
With this kernel when reboot first time my Nexus 7 I lost root and I couldn't restore again... I had to reinstall stock rom with fastboot, root again and than I reflash kernel with original Oxydo v12 :mad:
[Nexus 7 Android Development] sgt. meow:
If only the init.rc changed, there shouldn't be root issues. You sure it's not from the ROM's side?
[Nexus 7 Android Development] miki67:
I use the Google android 4.3 stock rom (nakasi-jwr66y-factory image)... No past issues with Metallice Kernel or with your original Oxydo... Every time I flashed these kernel I never lost root as with rhg135 latest one.
[Nexus 7 Android Development] sgt. meow:
And why would you use the carbon version with stock? I haven't tried it though but I haven't got any such report either. I'll check with him.
[Nexus 7 Android Development] thereal_bigjake:
I am using OxyDo with the carbon ramdisk on carbon and another CM10. 2 rom without any problems. No reason to use it on a non CM10. 2 rom...
[Nexus 7 Android Development] rhg135:
Why would you use my carbon one?

Sigh, editing time
[Nexus 7 Android Development] dareino:
Are you just removing the custom ramdisk from this kernel or making a change to it?
[Nexus 7 Android Development] rhg135:
Method

Being a masochist, I am compiling the carbonn bootimage with the source from the github, but a saner approach would be:

unpack the one in the v12 zip

unpack the one in the carbon nightly zip

repack it

zip it up again

but like I said I didn't and I run carbon builds anyway
[Nexus 7 Android Development] temasek:
It's because of multi-sim cm commits that requires an update to initramfs of this wonderful kernel.

Till its updated, u can try the following

1. flash CM10.2

2. Bootup and delete Phone.apk from /System/app

3. Reboot to recovery and flash this custom kernel.
[Nexus 7 Android Development] jfmcbrayer:
If you're still talking about the SmartassV2 problem, I think it's a code issue. I'm using the stock boot.img from Google's factory images site, but with my own kernel, which has SmartassV2 cherry-picked from your github. So probably not the ramdisk.

I meant to scatter the code with printk()s this weekend and look at it, but I was too busy. Maybe today.
[Nexus 7 Android Development] poondog:
Did you compile it into zimage or as a module?
[Nexus 7 Android Development] jfmcbrayer:
I compiled it directly into the kernel, but not as the default governor.
[Nexus 7 Android Development] sgt. meow:
Not the governor problem. I ran into issues with multirom. I'll still put out zimages if you guys think you need them. A boot.img zip will be there too.

Will your kernel support 4.4 in the future :) ?
[Nexus 7 Android Development] sgt. meow:
It already does if you can extract the zImage from the boot.img. I'll upload a version today or tomorrow. My internet's messed up.

In other news, Omni will be dishing out 4.4 builds soon as their Gerrit suggests (can't put up links right now, sorry) and I have a build system running.

OXYDO ROM will see daylight soon, hopefully.

nvidia released their 3.4.35 kernel for tegra 3 . Can you port it to grouper?

http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=tree;hb=refs/heads/linux-tegra-nv-3.4

http://nv-tegra.nvidia.com/gitweb/?...82dc6ff8e75b;hb=refs/heads/linux-tegra-nv-3.4
[Nexus 7 Android Development] sgt. meow:
I'll give it a go. I dunno how it's done, but I'll try regardless.

Thanks for this.
[Nexus 7 Android Development] riverzhou:
First , you need create new board files (named board-grouper in google's kernel) from board-cardhu (asus use this) or board-kai . They all in arch/arm/mach-tegra fold.

Second, you should port some grouper's driver from google's kernel source.

Last, try to make it bootable.

Wish you have good luck.

^_^

You can check the difference between nvidia's 3.1.10 kernel and google's 3.1.10 kernel , and to know what should you do from nvidia's 3.4.35 kernel to grouper.

It's not really that bad. But yeah rotation and camera doesn't work. I know dhacker29 got it working. But I'm waiting on AOSP blobs. I'll cherry pick a few things from OMNI ROM and CM as well.

Best news I've seen all week!
[Nexus 7 Android Development] fantabrothe:
great job Sgt. Meow!! (by the way, i agree with metallice about this nick!!!! lol)

Just a question: what are your first impressions with overclocking headroom with new 4.4 release?

I have an unlucky nexus 7, till now i was able to oc 1500mhz stable, 1600mhz with lot of random reboots, despite any overvolt applied, despite any kernel or custom rom i've tried in these months...it's a little disappointing, since my other asus tf300t can run 1800mhz flawlessly....any new hope????
[Nexus 7 Android Development] sgt. meow:
4.4 is quite smooth if you take into account the lack of proprietary blobs. OC is not really necessary.

The OC problem may be with your specific chip (hardware fragmentation). It's best not to attempt OC above 1.5GHz if your chip doesn't allow it. I can't go beyond 1.7 but I've seen my friend's nexus go up to 1.8 without any overvolt.

And metallice wasn't talking about this name.
[Nexus 7 Android Development] fantabrothe:
thx for your kind answer and for your job again..

PS sorry for my misunderstanding, i didn't meant to be rude
[Nexus 7 Android Development] Zeljko1234:
Overclocking will shorter battery life, increase heat, produce instability and even damage hardware. I cannot see real reason for overclocking except getting better benchmark result.

Android has a lot of room for improvement and optimization instead of just brute force. Read about flexycore ;)

Apologize for some kind of off topic.
[Nexus 7 Android Development] sgt. meow:
Oh no worries, man. I was kidding too. I don't care about my username.

Can you guys share how is battery life with this kernel :(

Iam having issue with idle or standby battery drain despite of more than 90% in deep sleep mode

I am losing 5% per hour

But when tablet in use battery is good. I can easily get more than 5 hours screen time watching movies

I am using buttered rom grouper version in my tilapia device (multi rom)

As i was suspecting battery drain is because of mobile standby but apparently even using wifi only rom doesnt help

I don't really know then. Can you try logcating and plase send me the logcat, okay? I'm trying out a new governor in the kernel, and I'll cherry-pick into the ROM again today. The problem will present itself when I'm trying to upload it on this slow-as-a-sloth Internet connection. Anyone can think of a solution? I'm open to pretty much anything now (as long as the idea does not sound evil).
[Nexus 7 Android Development] Zeljko1234:
Are you asking for solution to upload rom? If I need to upload something big over slow connection, first I zip into smaller pieces (using total commander for example) and then upload. In case of interruption just start uploading from one of pieces.

Right now I have high speed Internet access (about 20Mbps full duplex) and can upload whatever you wish.

Edit: I missed part about logcat. Of course I can, but restored my backup yesterday. Later I can flash 4.4 again and try. But would be better to try on your rom and get useful logcat for you.

I've been running some benchmarks and I noticed that V13 scores very badly on Quadrant I/O test, using any other version I score normally more than 7000 points but with V13 I've been getting results between 3500 and 4000. I tried different settings using Trickster but got the same results. Can anybody explain if this is OK? Thanks a lot for the help.

Did you do all the tests on the same rom?
[Nexus 7 Android Development] kareemgonna:
I first noticed on 4.4 CM that was released by koko98, I then tested it on 4.3 CM snapshot release and I get the same results, do you think that it's the ROM?

Edit: I flashed AICP and tested it and got the same scores then I installed version 12 and I got 8300!

Edit 2: After installing V12 I flashed V13 again on AICP and got good scores, still getting weird scores on 4.4 tho. Is that normal?

Edit 3: I did a clean install of AICP and then flashed V13 got very bad scores then I flashed V12 booted it up then went into recovery and flashed V13 got perfect results. I dunno but it seems like that V12 have to be flashed first!

I did the same test with CM snapshot and it worked, first I flashed CM and V13 and tested it, got bad scores, then I flashed V12 and tested it, got great scores, then rebooted to recovery and flashed V13 and it scored great!

[MENTION=4394172]sgt. meow[/MENTION], would it be possible to include range scalling toggle with the backlight sysfs? This allows the backlight to work better with lux, and for some reason allows the screen to be dimmed to a lower level than setting the minimum value alone.

Otherwise your kernel runs well with 4.4 :)
[Nexus 7 Android Development] sgt. meow:
You mean the otf scaling thing. Sure thing.

This kernel isn't 3.2.49; it is still 3.1.10. See https://github.com/souljaboy11792/oxydo-grouper/commit/3dde07c3b45cccd10dfa7f7ec2432fd769ae9af6

Fixing up the Grouper's board files to work with the new 3.4 Tegra drivers is extremely difficult and requires a great amount of skill. I don't know of any devs here for the Grouper who are capable of such a feat :(
[Nexus 7 Android Development] sgt. meow:
Yeah I know. I wanted to use the patches from pbeeler's repo. But back then I hadn't really realised that I wasn't *actually* updating to 3.2.49. I'll see if the patches help. Thanks for reminding me.

Just a question: does this have kexec support (or whatever is needed for MultiROM)?
[Nexus 7 Android Development] poondog:
Hi all, idk if this really belongs here but some may be interested

Could someone please explain what this is

https://android-build.linaro.org/builds/~linaro-android-community/nexus7-2012-linaro/

There is a linaro kernel there, it is compiled with 4.8.2 2013.10 (latest 4.8 toolchain) and is 3.1.10, feature wise it is the same as stock. I just flashed boot on my recently factory-imaged N7 with kk. Boot.img, so ramdisk and all

Anyone know what it is? [MENTION=4394172]sgt. meow[/MENTION]
[Nexus 7 Android Development] sgt. meow:
It seems to be a full build of the stock android factory images (no otapackage added to the make command) with the linaro toolchain. Or were you asking something else?
[Nexus 7 Android Development] poondog:
Are kernel sources out? :)

fwiw the linaro kernel (on stock factory ROM) benched 400 more than stock: 13473 vs 13890 on antutu

Exactly the same settings

I was just wondering and thought maybe you'd have more knowledge than me (which you do :)) cheers
[Nexus 7 Android Development] sgt. meow:
Kernel sources aren't out yet. I can definitely tell that there were no major changes in WiFi, Bluetooth etc. (core parts). There has probably been a change in SELinux (not only the Enforcing bit), and zRAM has been enabled (which is great for older devices). I'm guessing no major change in board, and CPU/GPU files either.

All this I'm telling because each 4.3 kernel can boot 4.4 with the proper ramdisk. And much of it is speculation by me.

I can't seem to be able to overclock the GPU to 600 MHz. (I tried using trickster mod and Franco kernel updater.)

It keeps reverting back to 484 MHz.

I'm running unofficial cm11 BTW.

Also, which governor is the best?
[Nexus 7 Android Development] friedsonjm:
I like row scheduler for its responsiveness.

I don't normally OC the GPU, but just raised it to 600 and am running AnTuTu to stress it.

When does yours revert, immediately, or after reboot?

FYI, I'm running Slim 4.4 ROM, and using Trickster...

EDIT: Keeping the clock speed at my normal 1500, and with GPU raised to 600, AnTuTu overall score is now 16297 an 'increase' of about 400 points, which may be slightly above noise level..

GPU is holding fast at 600.

Hope that helps! jf
[Nexus 7 Android Development] Angel0fDeath:
It reverts right after I apply it.

And I asked which CPU governor was best not which I/O scheduler is best xD
[Nexus 7 Android Development] friedsonjm:
If using Trickster, you ARE remembering to hit the checkmark at the top of the screen to apply it?

If so, maybe change to Slimkat 4.4 ROM, and find out if that 'fixes' it..

jf
[Nexus 7 Android Development] Angel0fDeath:
Yes, it even said applied. What's the difference between CM 11 unofficial and SlimKat?
[Nexus 7 Android Development] friedsonjm:
Governor, I'm using Interactive. I'm using CM 10 nightly on my GS3, and I find it has lots of bells and whistles I never use. Slimkat is much more stripped down, and for me, at least, more responsive.

With this kernel, I run it at 1500 max speed, and now 600 GPU, all animations turned off wherever I can find them, interactive and row, and for now, GPL just to test it, although I'm not very happy with its lack of features, little customization, and no built in backup etc.
