just so you know bponury updated touch control and it works on r86

now i can have back the best of two worlds
[Nexus 4 Original Android Development] Hanny:
thanks for your appreciation, glad that you like them :D

yeah, benchmark apps could do them but sometimes they simply **** up things and give inaccurate results while you dont know what's causing it. i have actually read the benchmark feedbacks even before i started testing. (although for today's case they revealed the truth)

so far, i always like to be a bit of systematic myself and conduct some tests - while i am certain about which part may give inaccuracy / error, and capable of commenting on the result (not more than score you can say when you bench) ;)
[Nexus 4 Original Android Development] Testraindrop:
Hm got another one again :(

Same error message.

Strange that I'm the only one, Franco do you think its my phone?

As far as I remember you said that too much UV would not cause Kernel panic but normal reboot?

Will have to do a wipe :(

[Nexus 4 Original Android Development] Hanny:
not remember if franco has said it himself (as UV is none of his business in my concept)

but i can confirm you that all my UV instability would not give any kernel panic messages but simply last boot reason: reboot.

therefore it should be something else. good luck!!

Re: [KERNEL][GPL][N4] franco.Kernel - r86

Maybe it could be the CPU ramping up doing that?
[Nexus 4 Original Android Development] tr1cky1:
Am I the only one with no improved hsic wakelocks on r86?
[Nexus 4 Original Android Development] scandalousk:
I've noticed the same thing for a while. Don't know what causes it tho'. I don't experience it on googles and cm10.1 stock kernel. But at the same time I don't experience it on franco's kernel for the nexus 7 either.

I can confirm it has nothing to do with the hotplug/dualcore/quad settings. I tried to set my minimum freq to 1026 as google uses that as a part of project butter and it seems to go away or at least it seems a lot less.

I can't really pinpoint as to what's causing it tho'. I'm guessing like you it's the cpu ramping up.
[Nexus 4 Original Android Development] jak3z:
I usually hate to read the kind of topics for Antutu blabla, Quadrant blablabla, but when you isolate tests (like 3D mode in antutu) and set-up a testing pattern, you can use benchmarks that show a reasonable stable results, and compare. If antutu would give me strange results with a testing pattern I would not even care about it. But I was getting an average score in a 10-test run, so I noticed something weird and decided to play a game.

Anyway always love your tests! :good: And franco job is always awesome. This is why we are testing the kernel :)
[Nexus 4 Original Android Development] KingBeike:
I notices too, that the "lag" is less when you icrease the min frequenz, but it is not gone!

With r86 for example ( it goes to 1,5Ghz when you touch the screen) then maybe the lag could be related to the cpu ramping from 384 to 1,5Ghz... and then after it should be gone when you continue touching it, because the cpu frequenz is at maximum. But that does not happen to me!

A little bit less laggy, but still present!

A request Franco, could you maybe build into your app a way to install a backup script for the kernel for flash protection?
[Nexus 4 Original Android Development] franciscofranco:
Definitely something is up with the GPU patches I merged after seeing Miasmic tests. Its weird to me as the code seemed alright before I merged them. I think I know what it is and I already sent a test boot.img to Miasmic with a slight change. Waiting for feedback now.

Thanks all for the feedbacks.

One more time. In the above post I included 2 logs for those smarter than me to review. I've since been told that it's called the "Sleep of death". My question remains - is this kernel related? If so, how do I prevent this? If not, I shall not clutter this thread with this question any more.

Hey Franco, love your Roms as always. I was wondering something though. Is it normal for my Asus N7 to outperform my N4 in quadrant? Both have your latest kernels flashed, but my N7 is running Smooth Rom and my N4 is running Muzzy's Rom. They are both set to your default kernel settings. Both run excellent but I was just curious.

Quadrant is old crap, use Antutu if you want to benchmark.
[Nexus 4 Original Android Development] grooves12:
Using r85, I get damn near 0% usage while idle... however it seems to burn through battery faster than stock while in use, using all stock setting on Aokp nightly 4.2.2

The big problem is I am regularly seeing data drops in the middle of usage... If I revert to stock kernel, data is rock solid, but battery usage goes up significantly when idle.

Re: [KERNEL][GPL][N4] franco.Kernel - r86

I had this a few times also. That's when I reported the wallpaper going back to default on a subsequent boot. This might be what was happening. Looks like you might have found the bug :)
[Nexus 4 Original Android Development] awtacular:
It happens often to me too. I've had previous problems when running almost any weather app at boot that has an icon in the status bar always caused my phone to get the welcome screen almost every boot on a 4.2.2 custom kernel. I never ran into problems on the stock 4.2.2 kernel. I guess having too many things starting at once isn't good.

Re: [KERNEL][GPL][N4] franco.Kernel - r86

i found a problem. i used cyanogenmod offical kernel or franco r72 before, then when i installed the 4.2.2 ROMs and franco r85 or r86 kernel , the wifi signal become worse. sometimes i could not even find the router i want to use. i have tried for a few times to install the different kernels, and it DOES happened. why? this is not a joke, i am serious. (sorry for my English :D )
[Nexus 4 Original Android Development] jak3z:
Franco is there any chance that the problem resides (if theres any change) on the "ondemand" governor? I was testing random stuff and I got better performance running interactive than running ondemand with r86. And if I recall correctly ondemand is now the default right?
[Nexus 4 Original Android Development] franciscofranco:
Ondemand is not the default.
[Nexus 4 Original Android Development] jak3z:
Then something was wrong with my auto-flash using your app, I always had ondemand as default :confused: since r47? or something like that?

I will keep changing to interactive then :)

Re: [KERNEL][GPL][N4] franco.Kernel - r86

I dont know about you guys, but I live in Nicaragua and my data connection used to take around 1 minute with the nexus 4 to become blue (active)

I didnt have these problems with previous phones like S3. Now with r86 it takes less than 10 sec! Thank you so much Franco, I bought your app a few days ago, and your hard work is totally worth it.

Pd: Seems that we are getting a bit closer to fix hsic wakelock, that would make this phone almost perfect :)

Just fyi blue does not show active connection. Blue means that you have connection to Google servers. Sometimes, for some reason, you might have working internet connection and not be connected to Google servers (grey data bars).

[Nexus 4 Original Android Development] Testraindrop:
Franco some technical questions...

1. As our phone has 2 Gigs of RAM, is it possible to allow the phone to use more of it for caching/preloading stuff?

Like a user-configurable setting, I want speed and I dont like to have 1.3 GB free all the time :)

Or is this ROM related?

2. Is the vibration setting in your kernel only for the haptic feedback or for all vibration events like calls?
[Nexus 4 Original Android Development] lnfound:
Re: [KERNEL][GPL][N4] franco.Kernel - r86

I believe not free ram is used for caching, just part of Linux and is not changeable. If an app actually needs it, it's made available.

Re: [KERNEL][GPL][N4] franco.Kernel - r86

You're right, I know it works like that but what I was trying to explain is that I am not able to use the data connection (receive whatsapps, check fb or use browser) until it gets blue, but now it get's blue faster, and that's a great improvement to me :)

You're right, but taking the time to do it and to make research, etc. Just accept the credit :P
[Nexus 4 Original Android Development] SubwayJrd:
As much as it's true that the Blue Bars don't MEAN that you have a data connection, based on Google's very reliable network, it's a quite GOOD indicator of it (I check for Blue Bars all the time on my Landlord's wireless, and it's never been wrong (dang DSL modem is crapping out, need to get him to request a new one)).

I was a UV maniac. Up to r83, I UV'ed -150mV all across the freqs on my Faster chip. Until one night I recorded an important video. When I played it back the next day, the sound was all messed up with static and clipping. From now on, no UV for me. It didn't have that big of an impact any way in prolonging battery life. In franco default settings I believe.
