[Nexus 7 Original Development] :
I shall say that I also noticed that r38's performances are not what we came to expect from franco's kernels. I (temporarily?) switched to trinity and the tablet is running much, much smoother. With r38 I consistently experienced stutters and lag.

Please note that I am using stock clocks with trinity (no overclocking whatsoever) and I dialed back the hispeed_freq from 1300 MHz to 910 MHz (I used 1000 MHz with franco's). Thus the performance improvements are not due to overclocking. Battery life seems to be pretty good as well.

I have been in software development for longer than I care to remember and I know that progress is not always linear. Sometimes one takes a wrong turn. I guess that this might be the case with franco's kernel. An alternative explanation might be that there are small but significant hardware differences that make franco's kernel less efficient on some N7s. Been there, seen that.

Last but not least, I am not a fan of benchmarks, stillI installed antutu and quadrant to see if the perceived performance boost could be measured quantitatively. Indeed, both benchmarks are giving results roughly 15% higher with trinity than with franco, again without overclocking.

Is it patched for multiROM?
[Nexus 7 Original Development] Brisma:
Try this one, r38 + multirom support compiled with linaro gcc 4.7.3 by me :)
[Nexus 7 Original Development] wejgomi:
Kexec message still after flashing this.
[Nexus 7 Original Development] Brisma:
I'm sorry, I've compiled the kernel with old config file.. There is only the linaro optimization :(
[Nexus 7 Original Development] MaNFr3:
How does it work on stock 4.2.1? Does improve battery life? Thanks
[Nexus 7 Original Development] siscim23:
Works well on stock, I have r38 with stock. With moderate usage, the battery lasts about 3 days. I unplugged Sunday morning, I have 40% left now.

Hi, I just flashed your kernel, everything seems to go fine. Just two question:

A) As in the new version of CWM recovery is not the option to wipe dalvik cache, I at least wiped cache, is that sufficien?

B) What app would you recommend to control the kernel? I use NoFrills CPU.

Thanks a lot! :)
[Nexus 7 Original Development] ÜBER™:
A) No need to wipe anything... "The only thing we wipe around here is our butt's"

B) I am sure he'd recommends his own app Franco.Kernel Updater, you can either use the free one or use the paid one :).

Deadzone? Its crap anyways.. it stutters for me as well... However nothing else does, everything else gets 30-50FPS.
[Nexus 7 Original Development] joaquinf:
Hi!

a) there is no need to wipe anything when flashing a new kernel. You are good to go

b) I'd recommend franco's app. It's an excellent tool and a great way to show him support

:)

Try decreasing the graphics details. By default they are set on "high", try a lower value to ensure smoothness

EDIT: darn that was Über fast :p
[Nexus 7 Original Development] ÜBER™:

I've solved it. Rebooted in recovery and did e2fsck on my partitions. It seems that some of the hangs with earlier versions corrupted /data filesystem.
[Nexus 7 Original Development] 1pop23:
I will say that going from R31 to R38 I did seem to notice some performance draw backs. Don't know if this is due to kernel or maybe other variables. other then that battery life is great and this is a great and stable kernek .

I am in love with r38. I could get close to 11 hours "screen on" time if I could stop playing games on it.

Amazing job Franco.
[Nexus 7 Original Development] osm0sis:
A big part of that is governor tunables. While we were having issues with the interactive patches Franco went back and forth from the GN "magic" tunables to defaults, so really, when comparing his builds not all things are equal (might explain some of the benching differences too). r38 is at what I believe are stock defaults again, with go_hispeed_load at 85, etc. which would reduce responsiveness. Try changing back to the GN "magic" tunables now that the interactive patches are stable, I think you'll see it back roughly to where you remember it, if not better.

Franco, wifi on stock kernel and some others was eating up a lot of battery. Do you think that's something you could work on? I haven't tested your kernel as far as battery consumption is concerned, so I don't know if you got that addresses. Anyway, keep up the good work!

Cheers!!
[Nexus 7 Original Development] espionage724:
His kernel (as of r4 I think) is using an updated WiFi driver. Not entirely sure what was improved or changed with it, but in any case, it is different then stock.

Franco. Loving this so far, although I miss being able to swipe through the action bar to the one I wanted.

Would it be at all possible to get a toggle for the nVidia PRISM Dimmer if/when you're planning on adding a Color Control section?

Pretty straightforward command to disable it:

echo "0" > /sys/devices/tegradc.0/smartdimmer/enable

To change how aggressive it is (untested)

echo "#" > /sys/devices/tegradc.0/smartdimmer/aggressiveness

As I understand it they're different kinds of IPS, so that's apparently why it's a no-go for the N7.

Running a stock rooted N7 3G (tilapia). Using the factory 4.2.1 ROM from Google with CWM and SuperSU.

Yesterday I flashed franco r38, it was the first custom kernel I have tried (on my N7). Now I don't get a phone signal at all. Signal bars are empty with no network name. If I try to choose a network manually it just says "an error occured while searching for networks" immediately. And this is sat next to my N4 on the same network which has a full-bars signal (on the latest N4 franco version).

I saw posts earlier in this thread indicating that this kernel worked fine on tilapia. Has anyone else had this issue?

I personally own the WiFi only version but a couple of things to try would be checking to make sure your baseband is not showimg as unknown under about tablet menu. Also maybe flashing your radio again and after with terminal app enter

Su

Killall servicemanager

Which will reset the system server and it will reboot the device. Failing that I don't know.

Recovery shouldn't effect radio, unless it was a bad flash through non stock recovery ie: md5 mismatch and flashing bad radios is never good

Yes that behavior is quite familiar to me. Especially when you don't use your device a lot. Every now and than the device checks the WiFi network to measure location. Turn of location access and those maps settings you talk about and you'll get proper sleep like this:

Since LP core is disabled in the kernel, how can i re-enable it ?

I like LP core and the idea behind 4+1 is super awesome :D

[Nexus 7 Original Development] xateeq:
I have tested the r38 for about week and i had no freezes or SOD.
[Nexus 7 Original Development] Laridia:
APN settings only apply to whether data is working, not to the signal in general.

Thanks for the ideas, I'll check/try this stuff at home later. If not I'll try re-flashing the radio and/or kernel, I assume I can get the radio from the factory image.
[Nexus 7 Original Development] The Gingerbread Man:
You might as well flash the whole factory image, that should eliminate any soft ware issue. You could also use Francos app to back up the stock kernel before flashing anything else and then it's quite simple to restore if you wanted.
[Nexus 7 Original Development] irminsul:
You could grab Franco's source and re-do the commits related to the hotplug and implement nvidea's version.

Don't know why you would do that, did you measure the difference in battery consumption between the two? I don't have any difference in usage.
[Nexus 7 Original Development] xateeq:
I have talked with almost all of the developers and every one has different opinion about LP core. I like it and i want it enabled (cos if i dont use it then why bothered with tegra 3 tab in first place)

And about the battery life then i am sure if i disable half of the processor ill be having even better battery life :P

I like r38 very much and i only like to enable the LP core :) (guess i have to make my own now)

Back to tutorials :D
[Nexus 7 Original Development] osm0sis:
Just because you feel like it? Get real. If you want LP core then don't use franco.Kernel. Go use one by one of those other developers that agrees with your opinion which is based on no evidence. Quit trolling about things you clearly don't understand; this is an experiment by Franco and so far anyone who's been smart enough to do a proper comparison has had good results or found there is no impact. Also thank god you can't thank your own posts anymore.

And another thing, who the hell down rated this thread so that it's only 4 stars now? That is some bull****.

Edit: Thanks to whoever voted it back up. :good: :)
[Nexus 7 Original Development] irminsul:
Nevertheless the discussion, it would be fun and useful to benchmark a companion core kernel and a kernel with Franco's version.

I'm talking about a most scientific approach as possible.

- loop a certain video on full battery as long as it lasts.

- keep reloading the same webpage as long as the screen lasts.

- let the tablet idle with screen of while keeping WiFi connections.

All under the same conditions: same place, same WiFi network, same brightness, same stock rom without additional apps etc

Only with a approach like that you could fairly measure differences. The Dutch techsite Tweakers.net compares battery life between devices with a similar approach.
[Nexus 7 Original Development] xateeq:
The reason behind me asking about LP core was this thread.

http://xdaforums.com/showthread.php?t=1889571

M-Kernel seams to have it turned on and overclocked a little and seams to have very little effect on battery life (i dont know about rest of the patches)

but that got me thinking and hence series of questions in kernel threads and finally got flamed at the end :)

Sorry if i crossed any lines but where els i would learn about LP core other then from a person who disabled it?

Again I am not trying to compare kernels i am trying to get my head around the idea of disabled LP core.
[Nexus 7 Original Development] NicoGa:
Indeed, if would be very nice to know more on this and to have clear evidence that one approach or the other is better ... However, seeing the results from bcvictory battery test, I m not sure there is a clear answer to the question.

Metallice propose a test based on a sinusoidal load, but I don't know how this can be achieved.

Sorry, but up until this point you've just been saying the same thing with no evidence to back it up, and then liking your own posts from a second account. Not very reasonable behavior, so it was hard to take you seriously. Instead of repeating yourself though, remember that Franco is at CES and unavailable to comment right now, so either wait for him to return and be active in the thread to try and get information out of him, or send a personal email. :)

I'm neutral with all this lpcore stuff

But, watching videos with the gallery app and battery has drained about the same as other kernels, with the lp core. Same voltages but this runs at 700mhz compared to ~500 with the lp core. But battery drainage is comparable atm so I'm still sitting on the fence lol

[Nexus 7 Original Development] 1pop23:
I haven't seen any difference really in battery life.
[Nexus 7 Original Development] superbobup:
IIRC Franco uses _thalamus' auto hot plug instead of nvidia's implementation. The motivation was that switching between the LP core and G cores was expensive, so disabling the LP core altogether was his solution. I think it's the same motivation for morfic and Trinity.

If I'm wrong please correct me guys :)
[Nexus 7 Original Development] The Gingerbread Man:
So with stock kernel it doesn't hot plug it's self? Your either running all 4 main cores or the so called lp core which I assume means low power?

Sent from my Galaxy Nexus
[Nexus 7 Original Development] superbobup:
No, I think it does hotplug. The only difference is that on stock, nvidia developed the hotplug driver (I don't remember the name) which works with all the cores. Franco uses a different hotplug driver that either (a) doesn't work with the LP core, or (b) works better without the LP core. I think it's the former, tho..
