Beautiful Widgets more than likely scanning the internal storage for its skins, do you have a bunch of widgets? Is this just idling or listening to music?

[Nexus 7 Android Development] underwaterjr:
I have a few widgets and this was idle all night. BW is one of them. I rebooted and it has seemed to stop. But was curious as to why it was happening.
[Nexus 7 Android Development] ÜBER™:
Well if its all idle then something has to use the battery... it just so happens that mediaserver was being used the most. Im guessing you have it set to auto refresh? that is more than likely why is that when it refreshes it also has to scan the internal for the image of what is needed depending on your weather. I always make sure everything that doesnt need to be refreshing automatically is off, such as weather widgets, i usually refresh them myself.
[Nexus 7 Android Development] underwaterjr:
Pretty sure BW was the culprit, I deleted it and battery consumption back to normal. Just threw me for loop cause battery life with this kernel has been phenomenal.

Hi there.

Just wondering Met if it is at all easy to add USB Audio out? I am looking at getting an external DAC for my Nexus, just not sure if your kernel supports it?
[Nexus 7 Android Development] Metallice:
USB audio is already supported.

Are you using the original charger and cable? I e found the cable to be very picky if its not the stock one

[Nexus 7 Android Development] xfrancis14:
Yes I'm using the stock charger and cable
[Nexus 7 Android Development] knitler:
I have that issue when charging from USB. I still dont get why it will only charge at a max of 820 miliamp when a 2000 miliamp charger is included. It takes for EVER to charge compared to my iPhone 5 or iPad3. and with USB limited to 500 miliamp using the wall only makes it charge 50% faster instead of the 300% faster its capable of.

It seems to be something involved with the device itself.

That the Nexus 7 has slow charging
[Nexus 7 Android Development] Räph96:
Kernel seems to be very fast, but on rasbeanjelly + a23 touchscreen is laggy sometimes. When i swipe down for the notification panel or the quick settings, it doesnt recognizes the touch.... Should i try a22? Or something else? Thanks a lot!

Edit: a22 fixed it

I just read the first few posts what's the difference between 666 550. Thanks. :)
[Nexus 7 Android Development] ezas:
So people don't get confused slow charging extends the life of the battery not how long it lasts between charges. After about 250-300 charge cycles your battery starts losing capacity. More smaller charges, not all the way down or up, will considerably increase the the time before this happens.

Faster charging does not reduce changing time by much. While it will reach peak voltage sooner, saturation charge will take longer. (Taken close to verbatim from http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries )

While thats true, thats why most batteries have a quick charge up to maybe 80-90% then s trickle charge after that.
[Nexus 7 Android Development] krazeecracker:
But your average person doesn't run it till its dead. I have a hard time killing it myself.
[Nexus 7 Android Development] ÜBER™:
Yeah only on the initial boot but even then no other kernel has done that to me.

Sent from my Nexus 7
[Nexus 7 Android Development] ezas:
I just double-checked at the web site linked, and li-Ions don't trickle charge but you are right that there is a protection circuit to keep the battery from holding at 100%. This is why it's not harmful to leave a device on a charger. But it still 'deepens' the charge cycle.

I don't want to give people the impression they need to stay worrying about this stuff. I'm talking about optimum care to prolong when your battery will slowly start losing capacity.

The site I linked above has a couple of good articles on Li-Ion batteries for those who want more info on the care and feeding of Li-Ion batteries.

great job on this kernel Metallice:D..my tab seems very responsive..also I like all the extra options available when using trickster..that is a great little app..my favorite part of this kernel is the fact that it will only at very highest go to my selected max MHz setting..with faux's kernel I couldn't for the life of me get it to not pass my selected max using many different kernel apps..pretty stoked this works like I need it to..

Companion core clock speed
[Nexus 7 Android Development] kerosin:
And have anybody compared a battery consumption between 550 and 666 LP?
[Nexus 7 Android Development] MrDrift42:
In theory the higher the clock speed the better the battery life due to the fact that it has to bring main cores on less often. I haven't done a personal comparison but I get outstanding battery life with 666 and a 1300 max speed so I haven't tested further. Benchmarks show significant improvement over stock without overclocking the main cores. In fact I had to turn the main cores down to 1000 to get scores comparable to the stock kernel.

[Nexus 7 Android Development] ÜBER™:
I could never get the CPU to push over to the main cores and would cause stuttering. Also the stock gov control for on demand makes my CPU use the max 1.5 all the time. Guess this kernel just doesn't like my device. :(

[Nexus 7 Android Development] ed33:
This kernel is really smooth just a shame about the boot up issues.
[Nexus 7 Android Development] Metallice:
Always an app problem. Usually multiple performance setting apps cconflicting. Often system tuner. Could you explain what you mean by push over to the main cores?
[Nexus 7 Android Development] ÜBER™:
Used trickster actually not system tuner. And by kick over I mean it would never use the main cores it would stick to the vitural core and use it 100%, very rarely did it kick over to the actual cores. I could tell because it was stuttering bad and looked at the CPU log in CPU spy and it was using 666mhz for the majority of the time.

Sent from my Galaxy Nexus
[Nexus 7 Android Development] Metallice:
Very strange. I'm going to release a24 soon. Switching away from LZO to fix slow bootups. Might fix your problems as well. What happens if you raised you min above 666?
[Nexus 7 Android Development] Stuphologist:
What boot up problems? I haven't heard of any machines that wouldn't boot the lower lp core build. Some machines boot slowly the first time, but that is a matter of patience. Sometimes some machines, mine among them, prefer to be flashed twice and mine in particular hangs if I try to flash anything with a ROM. That's nothing to do with the kernel, though.

Just didn't want an implied and incorrect criticism to become a meme. "yeah, that M-kernel, sorta nice if it boots." bleh.

Hey guys, I have a 16gb nexus 7. Which version should I flash? I flashed a23_666 from op and after boot, NFC and com.android.phone is crashing which means its a nexus 7 3g kernel. I am on cm10.1. Pls reply fast. Thanks in advance.
[Nexus 7 Android Development] Sveke:
Must be ROM, i see none of what your saying and i downloaded the from the links in op.
[Nexus 7 Android Development] bhu1:
I am on official cm10.1 nightly. BTW, I reflashed the ROM and everything is fine for now. Giving the kernel another try in a minute.
[Nexus 7 Android Development] Sveke:
Cm 10.1 just came out today so some kernels may not play nice with it yet.
[Nexus 7 Android Development] bhu1:
*deleted*
[Nexus 7 Android Development] Metallice:
That's not at all the reason whatsoever. Lol. I like how you completely made something up and convinced yourself that that is the reason :P.

The ramdisk is the problem in a23. The new build might fix it.
[Nexus 7 Android Development] bhu1:
Lols, haha. I assumed a bit too much, lols. I dont know much about how kernels work and all, sorry. I just use stock cm kernel on my sgs for past 1 year. And just rooted nexus 7 today.
[Nexus 7 Android Development] Metallice:
No worries. Try a24 and see how it goes.
[Nexus 7 Android Development] MrDrift42:
A24 seemed to boot up at the same speed as 23. That being said I can't say a23 booted slow. Everything seems smooth so far.
[Nexus 7 Android Development] Allosaur:
a24 looking good

So far so good with a24 666 on my 16gb N7 AOSPA 2.99 B8. USB stick mounting fine with otg cable. Used to use Stickmount but have now uninstalled it. A24 doesn't seem to have fully resolved the slow initial boot but waiting 3 mins for 1st boot is no hardship.

cheers, A
[Nexus 7 Android Development] sert00:
ehi metallice,what type of compression you used before for the ramdisk?did you see improvements doing so?in my personal test i didn't see so much difference between them..xz,gzip etc..

thanks for the reply and for this great kernel!:D
[Nexus 7 Android Development] bhu1:
Flashed a24, working properly. I don't know about others' problems with booting, but it booted for faster/same speed as every time, which is very fast.

Everything seems super smooth, max frequency was 1.6 GHz, I changed it down to 1.3 GHz. Good kernel. I hope battery will be very good as that was the reason I flashed this kernel.

[Nexus 7 Android Development] kazemitsui:
How come when I use trickster app to lower it from 340 to 204 or 102 it always resets back to 340? Even if I set save it and have it set for enable on boot?

not really a complaint but I have noticed that I can never set it lower than 340...
[Nexus 7 Android Development] GreyCelt:
Does no one read anymore? If you go a few pages back Metallice talks about this exact issue and even has pictures. :banghead:
[Nexus 7 Android Development] Metallice:
Is that rhetorical?
[Nexus 7 Android Development] Sultanxda:
I hate to bring this back up after so long, but I finally got around to compiling a kernel with the pixclock increased to 85Hz. Perhaps there is some secondary effect to the device as a result of the pixclock increase, because things are definitely much smoother. Animations for things like opening apps or opening the app drawer are noticeably more fluid. Since the hardware is locked to a refresh rate of 60Hz, I'm curious as to what is causing this. Any theories?
[Nexus 7 Android Development] cakessi:
My N7 seems to be charging a bit faster with a24. Were there any optimizations for that or am I "seeing things" again?
[Nexus 7 Android Development] kazemitsui:
alright i just wasnt following this indepth until recently and didnt read everything regarding this...

I do see that the min is 102 but in trickster it keeps it set to 340 i guess, even though the REAL min is 102... kinda odd or is there a fix for that I still cant find?
[Nexus 7 Android Development] danielsf:
Just a thought, maybe the secondary effect off pix clock increase to increase fluidity is because the GPU could be scaling higher to maintain thoughs refresh rates? Like on the int s3, the stock low freq is 160mhz, if you remove that and replace it to 266mhz, UI interactions are considerably smoother (I know different GPU architecture, but same principle), so maybe the secondary effects is that the gpu is at a higher frequency to try to output those extra frames, which in turn increases UI responsiveness?

CM10.1 boots with A24 - many thanks :)
[Nexus 7 Android Development] apex84:
For me it boots on CM 10.1 but it gets stuck at the Google logo for 2-3 minutes before loading the ROM. First boot after flashing it was normal but all subsequent have been slow for some reason. This is a24 btw.
[Nexus 7 Android Development] adstraylight:
For me, the long boot is when rebooting from recovery, I just tried completely shutting down, then booting, and it was pretty quick.

EDIT : I think I have the answer, I think it depends upon the bootloader version, here's what I've found..

3.34 – boots fast

3.41 – slow reboot, fast normal boot

4.13 – boots fast.
[Nexus 7 Android Development] bhu1:
Just curious, how can one update their boot loader version. I already have 4.13 though.
[Nexus 7 Android Development] Nosferatu.:
I don't know if it's a ROM bug or Kernel bug but I found an issue.

When booting device with headphones in any attempt to adjust volume by either the hardware buttons or settings causes said app to force close. Unplug headphones readjust volume and plug them back in and works fine. Weird but reproducible.

[Nexus 7 Android Development] apex84:
Download the factory image from here.

Extract the "bootloader-grouper-XXX.img" file and reboot your Nexus 7 into bootloader mode and flash it with "fastboot flash bootloader bootloader-grouper-XXX.img" command.

You have to point it to the location of the img file, for example: fastboot flash bootloader C:\bootloader-grouper-4.13.img
[Nexus 7 Android Development] NicoGa:
From my understanding, with a24, if I plug a USB key in my Nexus 7 it should mount automatically in /storage/usbdisk ? (no need of a program such as stickmount).

However, this folder is always empty.

Does anyone else tried this new functionality ?
[Nexus 7 Android Development] ed33:
Empty with me also.
[Nexus 7 Android Development] R3dbeaver:
Mine always works with stickmount just fine... a23 and a24.
[Nexus 7 Android Development] Metallice:
Automatic usb hotplug SUPPORT. Your ROM has to include it like PA for example.
[Nexus 7 Android Development] NicoGa:
Ah ok, so it's normal it does not work if we are on the stock ROM.

In fact, we just need to add the following line in /system/etc/vold.fstab, and reboot ?

dev_mount usbdisk /storage/usbdisk auto /devices/platform/tegra-ehci

(at least it works for me)

I had a weirdness. The Play store was updating the Make Your Own Clock widget application and the N7 locked up tight. Rebooted, and it wouldn't come back up. Went to the boot loader and restarted, only got to the Google screen. Reinstalled the kernel (twice, because that's how my N7 rolls) and it came back up. I posted this in the PA thread, too, but it seems more like a kernel issue. Bug or quirk or random oddity, I have no idea.

Questions/clarifications

If I am coming from franco kernel, do I need to reflash my ROM in order to reset the ramdisk (as it is tweaked in franco kernel) before flashing M-Kernel ? Do I need to wipe cache and Dalvik cache ?

Concerning Jay's Recipe for Buttery Goodness: do I need to add a script in init.d to activate that functionnality ? or is this already included in the kernel ? (I know that the OP mention this but it is not that clear to me).

Sorry for such a late reply. But app? I don't know what you're referring to. It's the system in general, it just begins to feel laggy and when I go into the performance section I find out it under clocks itself to 700 mhz.
