Running your kernel with Scott's clean rom 3.0 got a quadrant of 6000+. Was getting 70+ fps!!!!!!??? Haven't got those kind of frame rates from 520! How am I getting that from 484?? Running on demand at 1.5 deadline. All I can say is thank you and welcome back!!!:D

Great to have you back, man! Hope all of your RL stuff went well. While you were gone, Metallice forked your source and kept the dream alive :) You should check out his git
[Nexus 7 Original Development] navalynt:
There's a bit of weirdness on the 3G. If I disable WiFi and search for an available mobile network it tells me "Error while searching for networks". If I leave WiFi on and search for an available mobile network it successfully finds all the GSM networks in my area.

So it seems like the WiFi toggle is somehow also being tied to toggling all network access. When I pulled the power cord on my router to see if it would connect to 3G without a known WiFi AP in range I noticed that while I can still see and register on the mobile network it won't give me an active data connection.

Right now I'm at home on Windows 8 with some really FUBAR driver issues. When I get to work tomorrow I'll recreate it again and pull a last_kmsg for you.

[Nexus 7 Original Development] _motley:
Thanks gentlemen! I did see that Metallice had done the great deed, although I haven't studied his fork yet to see what he has done. This is what I love about open source and the group of folks we have on XDA.

Thanks for the feedback on 3G, it is much appreciated. I merged in the source from Google's tegra repo, but maybe I missed something in the networking config necessary for WiFi/3G inter-operation. Can you or someone else pull and post the /proc/config.gz from a 3G stock kernel, or one from another kernel that has 3G working properly would be fine too I guess...just let me know which kernel it is from. I'll do more research and see what I can find. If there is another custom kernel with known 3G support, that would be good to know.

Can anyone tell me what a safe temperature range is? I tested a 1.5 oc on stock voltages using the latest kernel with asphalt 7 for five mins or so and temps reached 79 which scared me quite a bit. Seems UV solves most of the temp problems but I fear I may have caused some permanent damage already. After the temp scare I shut off the tablet but it wouldn't seem to turn on for a while too. Does the Tegra 3 chip have built in thermal protection like on modern x86 chips? Thanks.
[Nexus 7 Original Development] jpeckinp:
I'm using stock ROM 4.2.1, rooted and unlocked and for some reason System tuner will not keep my settings. It defaults back to 1ghz and conservative gov.

I've set it up for On Boot Completed on everything except Force All and Clear Cache.

Any hints?
[Nexus 7 Original Development] Jay Aristide:
79 is hot as holy hell, but if the chip was in any danger it would have shut off on it's own. That's a *really* alarming temperature though. IMO, anything over 60 is too hot.
[Nexus 7 Original Development] Metallice:
I don't think I've ever broken 50. My 7 isn't the best when it comes to overclocking, but man does it run cool... 38 right now...

Here's the config.gz file from the stock kernel included with Paul's J2 ROM.
[Nexus 7 Original Development] korgmotif:
Thanks for the info. Glad to know I didn't do something completely idiotic. Well right now with a -125mv UV with 1.5 OC I get max 58. Guess I got a hot one. Any more UV starts giving me a significantly lower antutu score. Right now I get about 14400 in antutu 3. Also noticed that after UV asphalt lags a lot less. I guess that means tegra starts throttling if it gets too hot right?

Motley, does your latest kernel support 4.1.2? If not, do you any plan to continue supporting 4.1.2 kernels?

Thanks.

[Nexus 7 Original Development] okyere:
You, sir, are welcome back!
[Nexus 7 Original Development] _motley:
Awesome, thanks guys. I will compare the kernel config and any commits that I may have missed from Google. I'll post another build as soon as I think I have something.

Make sure you are not using the performance governor for the CPU for daily use or for gaming. I have forgotten to turn it back to interactive before and it will get much hotter than normal just sitting there on the desk.

Hi, I have a git branch for that here https://github.com/motley-git/Kernel-Nexus7/commits/motley_v2. I built and tested a 4.1.2 kernel for my own use (I call this my v2 kernel that was never released, hence we 4.2 is my v3 kernel series). Then I got busy again and 4.2 came out. What I could do is create a branch from the 4.1.2 branch and build one last build for 4.1.2. I am not sure if the 4.2 kernels are backward compatible with 4.1.2 ROMs since I have never tried myself, but I am sure others would know.

build 234 posted

Build 234 posted to hopefully address any issues with 3G. I found that I somehow missed CONFIG_USB_NET_RAW_IP=y in the config. This is the only change from build 233.

navalynt, thanks again for posting the config.gz, that made things easier for me. Hopefully you and DiamondBack can let me know if it is working better and hopefully we can call this case closed. Fingers are crossed!
[Nexus 7 Original Development] _motley:
Cool, I will checkout that branch and build tomorrow. It will be nice to fill this gap since many are likely still running 4.1.2.
[Nexus 7 Original Development] Diamondback:
Writing from mobile data right now, seems to work fine :p

However, sometimes the upload-download indicator doesn't show up properly. faux' kernel has this issue too though. Maybe even another 4.2 bug... Works fine for the wifi icon.
[Nexus 7 Original Development] _motley:
Great, thanks for the feedback DiamondBack. The up/down indicator is probably an OS level bug, but I guess we'll wait and see what pans out. I was using it on my WiFi tablet last night. All was fine at first, but them I started getting touch screen issues. It was either the touchscreen driver, or something else on the bus creating issues that manifest themselves in the performance of the touch driver and UI. For example, I couldn't press and hold to pop wallpaper choices from the launcher. Scrolling web pages became difficult because it didn't know when you were scrolling or clicking. I am still not sure if the kernel caused it or whether I was experiencing some hardware issue, although when I flashed back to the previous version of the kernel, it hasn't come back. I saw some GPIO errors in the kernel log, likely due to a driver mismatch, so perhaps the driver is not happy unless the proper modem hardware is present. I was hoping to have one version that supported both WiFi and 3G. I'll study faux's git to see what I may be doing differently.

great kernel

Good to see you are back Motley!

For me the best kernel I have tested so far (I am running 4.1.2 stock @1.3 Ghz@1025mV, interactive governor, with Jay's buttery goodness).

Very snappy and responsive, flash 100% working, no popping sound issues, high fps, highest benchmarks (not that important but nice anyways), no cpu heating, boot up seems fine so far. Battery drain might be a bit high but still monitoring...

One thing I am not sure about whether it is true or placebo: I have the impression that the touch screen accuracy somehow became worse. There seems to be a slight topwards+rightwards offset since I am using this kernel. I don't know if that could be possibly kernel related or not but I did not change anyhing else and never noticed that issue before.

Keep up your great work!

EDIT:

Vertical scrolling is choppy, no more long+continous scrolling possible.

EDIT2:

Horizontal scrolling is also messed up.
[Nexus 7 Original Development] Metallice:
Hey motley as you start to catch up with patches and what not... Can you let me know if you figure out what causes flash corruption? That one's been bugging me. It's not like I even use flash but some people are stuck back in the froyo days I guess :)

[Nexus 7 Original Development] Jay Aristide:
That file stops your custom max CPU frequency value from getting reset to 1.2ghz every time you wake your tablet.

[Nexus 7 Original Development] Jay Aristide:
I understand why you use anykernel, but for those of us desiring init.d support, it makes for quite a few more steps (extracting the ramdisk from the boot image, modifying it for init.d support, repacking it, and finally reflashing it).

If anykernel is the way of the future -- which it appears to be -- what are the chances someone (maybe you) could make an init.d support injector zip that repacks whatever ramdisk is present with init.d support?
[Nexus 7 Original Development] kev94:
Has anyone tried this kernel with paranoidandroid ?
[Nexus 7 Original Development] espaciosalter20:
Don't know, but on my Xperia sola I didn't have to modified ramdisk in order to enable init.d support, I just use doomlord's init.d enabler. I think this might work with nexus as well

[Nexus 7 Original Development] poondog:
Isn't there a method to get this working regardless of kernel without altering the ramdisk?

Alternatively I guess you could flash someone else's kernel that has a ramdisk and init.d support

The anykernel updater will pack that ramdisk with the zimage from this kernel :)

Anyone having their N7 turn off after it gets a full charge with this kernel?
[Nexus 7 Original Development] phonic:
It's not the kernel. Stock does the same thing.

i actually made a thread about it because I was concerned. Everyone said the same thing happens to them too, regardless of kernel/ROM/etc.

The belief is that the device does this as a safety precaution once the battery has been fully charged and in deep sleep for a long enough time (not sure how long, but at least a few hours). I imagine it does this to help preserve the battery and keep the device from overheating.
[Nexus 7 Original Development] _motley:
On only OC to 1.3...thanks for the logs. I see exactly what the problem is. I should be able to fix tonight after work.

Thanks!

Edit: corrected, responded to wrong post and removed quote
[Nexus 7 Original Development] phonic:
Were you charging off of A/C or USB via computer?

Out of the four overnight charges I've done, three of them resulted in the unit being off when I woke up.

The fact that this seems to be by design makes me reluctant to turn the 'feature' off even if there was a way. There is a possibility that during the QA/design/testing phase, the engineers determined that the battery (or something else) got damaged if left on the charger for a longer period of time, so they implemented this as a work around. Just hypothezing here.

All I know is, this is the first device I've had that does this, so I think there might be a reason.
[Nexus 7 Original Development] thracemerin:
@motley - Not that I see a huge performance difference between compiling on 4.4.3 and 4.7.1, but if you want to try compiling off the linaro 4.7.1 toolchains, this commit should fix the DIV mismatches that cause the build to fail.

just use an app like Script manager to enable it. just open up the app. go to the directory where the zram file is at. then click on that file. click the Is Script one(I believe its that one. you will find out once done and you press run. it'll say if its running or not. if not then try the executable one). then just toggle the icons for Superuser & boot. then press run. now you good to go. now whenever device reboots, script Manager will automatically enable ZRAM.
[Nexus 7 Original Development] Metallice:
Thanks for this. Tried out your kernel with some modifications... just FYI

520Mhz GPU works fine on my tablet. Not issues or heat problems. Nenamark2 went up to 58.5fps. It's a small change so I'm not sure if its worth it.

Compiled with Linaro GCC 4.7 and a whole lot of linaro compiler flag optimizations and other compiler flags. Seems faster. Quadrant went up above 5000 for me which is a decent improvement (466 mhz gpu). Hard to tell if it really make a difference in usability considering how smooth jellybean is already.

Thanks for the kernel and especially for the source :)
[Nexus 7 Original Development] cobhc:
Any chance you could post a link to it for any of us to try?
[Nexus 7 Original Development] _motley:
Cool, thanks. Someone posted some helpful grouper code fixups a couple pages back, so I am going to try Linaro myself. Can you share your compiler flags and I will give it a try and post for everyone, as well as in github?

I am testing a little trick myself right now...Nenamark up to 59.6, but without increasing GPU clock any further. Will likely post fairly soon and then try the Linaro toolchain as the only change in the following release. It am using 4.6.3 (ezterry chains) right now, but was first using a slightly. The thing that is suffering for me right now it seems is my floating point scores. Back before I was getting better scores in this area and I am not sure what changed besides my ROM and kernel LOL. I wonder if the Linaro with optimization might really help with this raw math? It seems like it might.
[Nexus 7 Original Development] _motley:
[

Not sure on this one...I haven't changed anything in the source, but compiler optimizations and different toolchains could play a role. I am not really having any issues myself that I have noticed, but I will pay more attention. I have a prime too, and it has a much weaker signal than this one does. They are known for weak WiFi signal.

Thanks, I appreciate it. I saw the post at work today and wanted to go back and find it before it was too late!
[Nexus 7 Original Development] Jay Aristide:
I can't imagine how you'd do this without modifying the ramdisk. And, yeah, I could do that, but I'd prefer something a little more elegant. Maybe I'll make a CWM flhable zip that does nothing but disassemble the ramdisk, check for init.d support, add it if necessary, and reassemble the ramdisk... Would be kinda like an anykernel zip, but in reverse
