Re: [KERNEL][GPL][N7][13 MAR] franco.Kernel - r48

Actually I had a similar problem some weeks ago after a kernel flash, my speakers went 'crack' and the sound was distorted.

Reboot didn't fix anything, I really was afraid I might have broken it.

A clean install of another ROM however fixed it - I guess there exists a driver problem, because if I remember correctly there were similar problema with trinity a while ago - can't remember any lasting hardware issues though.
[Nexus 7 Original Development] 0rigami:
I never played with the voltage settings.

I never used apps that boost the volume.

How do you know a kernel cannot fry a speaker as it manages the CPU, GPU..etc. that can cause short circuit to all the related hardware?

And my speaker died from a freeze, not SOD.

Re: [KERNEL][GPL][N7][13 MAR] franco.Kernel - r48

Kernels can alter some things regarding audio, such as dynamic range compression (something like that I think) it shouldn't matter even if the kernel is at fault. Its YOUR fault for flashing this kernel and you are held liable. NOT the developer.

I think now would be a good time for Franco to add a simple disclaimer to the OP, so some people don't point fingers to others.

Also had lockscreen issues since upgrading to r48. Reverted to r47 and problem solved.

It may also just be my imagination but r47 is the only kernel I've flashed so far that has minimized/eliminated screen flicker.
[Nexus 7 Original Development] hhwong:
I actually did a few test with my tab, CM doesnt go well with r48, no issue with r47, PA doesnt go well with r48, no issue with r47, stock doesnt go well with both r48 and r47.

When i say it doesnt go well with the rom, i simply means generating excessive heat/unreasonable battery drain, comparing to the roms original kernel.

At this point, i think it is safe to say my tablet simply dont like r48 lol. Waiting for r49 to see if anything improves :)

I take back what I stated earlier about not having the heating issue. I finally took my tablet out of its case for cleaning and it was very warm even with default settings. This needs fixing. I really like this kernel for its battery life and performance.

[Nexus 7 Original Development] ThePlasticBling:
which version can i use with cm10 (4.1.2)? Are these only compatible with 4.2?
[Nexus 7 Original Development] osm0sis:
Something like r30 was the first for 4.2.x I think? Just to make sure, rather than me search the thread to find the answer, why don't we cut out the middle man and you search it yourself. This is one that's been answered more than a few times. ;)

Yes, the OP/title should probably have that info like it does in the GN thread.
[Nexus 7 Original Development] ThePlasticBling:
I've tried searching but couldn't find anything. Sorry. I honestly don't know what to search I've tried "4.1.2" but it comes up with every post with the numbers 4, 1, and 2 in it I've also tried "cm10" but I only saw things that had to do with cm10.1
[Nexus 7 Original Development] osm0sis:
Running franco.Kernel updater app would also have worked to find out.. Also looking here: http://minooch.com/franciscofranco/Nexus7/ :p

4.1.x -> r25

[Nexus 7 Original Development] jsn:
I experience these delays too.

Most times, it takes at least 2 to 3 seconds and at most about 8 to 10 seconds.

And yet, sometimes even longer, almost thinking it locked up (but it isn't).

It almost seems the powerbutton doesn't respond nicely. The magnet-sensor

for the smartcover seems to have less issues turning on the device.

Not sure whats going on here. Maybe its the combination with DashClock

and a few plugins on the lockscreen. Still trying to figure out what the culprit

is here .. I've temporarily switched to Leankernel, but this doesn't have these delays.
[Nexus 7 Original Development] _Johnito_:
I also have a small delay when waking from deepsleep (something like 1 full second or so, but it can be just a bit longer). I'm not using any widgets on lockscreen, except the pattern thing to unlock.

I'm currently running an AOSP based ROM and had this "bug" with AOKP based ROMs too. Definitely a kernel thing. Well, thats not that bad.

Silly question, how to auto run this script?
[Nexus 7 Original Development] osm0sis:
It's an init.d script, so it's designed for running at boot. Download it to your device, rename to remove any extension downloading it may have added (.bin or .txt). Place it in /system/etc/init.d/ (create this directory if you don't already have it on your ROM). Then execute this command in Terminal Emulator to set the correct permissions for file and folder all at once: su -c chmod -R 755 /system/etc/init.d

You'll get a root prompt, allow it. Then everything should work on your next boot. For the script you need to set your scheduler in f.Ku or Trickster first then it will automatically populate your active scheduler with our current test values after a reboot (so if you change schedulers another reboot is required to set it again). Let us know how it goes. :good:

Edit: If that doesn't seem to work then your ROM is probably at fault. Remove /system/etc/sysctl.conf as it can conflict even with settings that aren't altered by it.

Run it in terminal since it's simple and does it all at once. Then check in an explorer, the perms on both file and directory should be rwxr-xr-x

That will set both directory and files all at once. :good:

I was getting longer & longer screen on times. The device also seemed to have general sporadic slowdowns, that I never noticed on r.48.

All the normal things you'd do regardless of the kernel that's installed. Reboot the device, aeroplane mode on/off, move location to improve GSM coverage, try a different network SIM, use WiFi etc etc.

Re: [KERNEL][GPL][N7][13 MAR] franco.Kernel - r48

In your picture it says you have your max frequency at 1300mhz but you are using interactive so it only goes there when it has to.
[Nexus 7 Original Development] jarayn:
makes no difference for me. Same delay.
[Nexus 7 Original Development] nazz.rule:
It stops/pauses at 1000MHz because the hispeed_freq is set to 1000MHz by default.It will only get to 1300MHz if the loads reach a certain level.You can change the hispeed_freq using an app like franco.Kernel updater or TricksterMod.

Feel free to correct me if I'm wrong.
[Nexus 7 Original Development] osm0sis:
Yup. For me it's been there since JB4.2, likely due to the lockscreen widgets since it affects my GN as well, and the Lockscreen Policy app improves it. No noticeable change between r47 and r48 here though.

Re: [KERNEL][GPL][N7][13 MAR] franco.Kernel - r48

The strangest thing happened to me last night. I decided to wipe out fku's data & cache to make sure I was running with all the default settings. I did that, rebooted and when my N7 came back up, fku began requesting su about once every 2-3 seconds (that's a guesstimate since Superuser's logging isn't granular enough to show seconds, it only shows the hour and minute). So I rebooted again and it stopped. I can't reproduce it, and I don't know if it's an fku bug, a bug in the relatively new Superuser, or an interaction between the two.
