I'd say go with AOSPAL if you don't wish to experiment as AOSPAL is supposed to work on all ROMs.

Hi,

do you have news about the kernel working on CM Rom?

i tryed again to flash the kernel on last CM nightly, nothing, still bootloop on CM logo :(

im very sad for that, I would like to continue to use your great kernel but i cant :(

please try to investigate and fix this issue :fingers-crossed:

thanks
[Nexus 7 Android Development] sgt. meow:
I'll try to update it this week. School keeps me busy a lot. I haven't been able to build AOSPAL either.

Thanks! I was trying to figure it out for last week

[Nexus 7 Android Development] jamiethemorris:
I searched the thread and didn't really see anyone with this problem, but am I missing something for getting wake options to work? I never got them to work, as soon as the screen went off it would never wake up. This is on purity with the latest cm-f2fs kernel. I wasn't sure if I should use cm or not for purity, but it booted so I figured it was the right one.

Hey guys I got USB otg to work so it can read micro sd card readers but is there a way to get it to read 2.5 inch external hard drive?
[Nexus 7 Android Development] Ajenaton1968:
Help me please

The first is say sorry for my poor english.

Sorry too if i say something stupid

I cooked my own rom stock kk and this kernel is exactly what i looking for, i like very much doubletap2wake.

I flash the kernel, V16-aospal (2nd February, 2014),and i go to sys/android_touch/doubletap2wake and i edit it with root explorer and i change 0 to 1.

All works perfect, but if i reboot doubletap2wake return to 0.

I tryed to take it out and edit with notepad+ and is imposible to return it to the tablet.

I made a script and put it in init.d and does not work

I tryed to do in the terminal and does not work

I downloaded Trickster MOD and i trayed to find the place to change the value and nothing.

Can you help me???? can you explain it to me?

EDIT: Ohhh my god, 48 hours fighting with doubletap2wake, i wrote this post and i find it in Trickster MOD, thank you very much and sorry.

Do you guys really see a performance boost from using f2fs? I have tried it and it feels the same to me.
[Nexus 7 Android Development] bjcrj:
I couldn't tell the difference. It seemed the same to me too. Both all and data only.
[Nexus 7 Android Development] Reiven89:
Hello, thanks for this kernel...very good kernel only problem i have with OTG is that when i change the usb host fixed install mode to 0, it return to 1 after rebooting ... I tried both using terminal emulator and modifying the file from a file manager but still after reboot the usbdisk folder give me error permission denied and the usb fixed install mode return to 1..any help would be appreciated :)
[Nexus 7 Android Development] robgee789:
I had the same problem mate
[Nexus 7 Android Development] PrizmaticSmoke:
I would say that over time, my Nexus 7 had become more and more sluggish in general. Apps would hang when launching, or crash when lightly multitasking. System would freeze completely and become inoperable until I rebooted. Simply navigating the settings menu became a chore, as it would lag when opening settings, lag when scrolling, delay of several seconds when selecting an option. This all seemed even worse once i upgraded to KitKat.

I tried just about every ROM/kernel combo out there in hopes of relieving this, and some seemed snappier than others, but all of the above still seemed to apply, maybe just not as severely. My wife also was experiencing the exact same thing on her Nexus 7.

After formatting /data partition to f2fs, this was greatly improved, the issues i was experiencing were pretty much gone. It felt like a brand new device again (or even better)! I feel like i finally found the solution!!! Made the change on my wife's as well, and same thing, massive improvement, and no more complaining about her tablet freezing/crashing. :laugh:

I've now switched to all f2fs slimkat, it's only been a day now, but it does seem even snappier with certain tasks and in general.

Maybe just formatting /data and starting with a clean slate has a lot to do with this effect regardless of the file system being used, but hopefully f2fs is better over time than ext4 was for me and my SO. :fingers-crossed:

That's just my experience, but it really did seem to breathe new life into a couple of devices for me.
[Nexus 7 Android Development] yukkio:
Hi, so formatting system too, is it a improvement? I only have data.
[Nexus 7 Android Development] Icewyng:
I did see a difference with all-f2fs SlimKat. Combining it with ART speed it up even more.
[Nexus 7 Android Development] lembang:
[MENTION=4394172]sgt. meow[/MENTION]

Yes it does.. My nexus 7 tablet run really smooth with /data in f2fs..im running ur AOSPAL with 3.2.5 experience kernel..
[Nexus 7 Android Development] waz675:
Looks like I'm going to format both of the spare groupers to f2fs! Since they're mainly YouTube and kids games for our 2 kids under 5, won't be too much to do the format. I dread doing my flo which is my main device, 420 apps and counting when I do dalvik wipes heh
[Nexus 7 Android Development] thoiloidainhan:
Maybe it lacks a good kernel to realize the full potential ?

The inbuilt heats up my n7 pretty bad ?

I do notice restoring app+data using titanium is quicker
[Nexus 7 Android Development] sgt. meow:
I'll merge in the 3.2.56 patches (they were submitted today) soon and there will soon be a release. In the meantime, I'll experiment a bit.
[Nexus 7 Android Development] jfmcbrayer:
I haven't tried it, but I get the feeling that the placebo is strong with this patch. Or it may be that people with models that were affected by the lack of fstrim/discard in earlier ROMs are seeing some real benefit, but not so much everyone else.
[Nexus 7 Android Development] sgt. meow:
Maybe there are really performance issues in the 8GB models. Certainly none in my 32GB model. Nice experiment though.
[Nexus 7 Android Development] scotyard:
Thanks for this kernal. There are so many versions in the dropped folder. If I am not wrong, I have to flash just 1 file. Which version do i download?

Nexus 7 2012 cyanogenmod 11 nightly.
[Nexus 7 Android Development] sgt. meow:
The last one. Download both versions. Take a backup of your current boot partition. Flash the AOSPAL one first as it is most likely to work. If that doesn't try the other.

Kernel settings?

Is there an app that can be used to tweak kernel settings?

Or are most just using the default kernel settings?

[Nexus 7 Android Development] sgt. meow:
Interactive @ 1.5GHz and GPU @ 484MHz (or even 446MHz) + no screen wake controls (if you don't use them) should give you excellent battery life and performance. You can adjust CPU speeds too.
[Nexus 7 Android Development] keneth_c:
Gonna do this right away... Much appreciated dev.

You think there is a possibility of having the above mentioned recommended settings in 1st or 2nd post? Would help many others don't you think? Upto your discretion.

Gr8 work though dev...

This is the 3rd kernel I've been on since I started trying on kernels... And so far the best :)

Thank you! Running great so far on the most recent AOSPAL with /data on f2fs. :good:

Any chance of an all-f2fs compatible AOSPAL release? Runs great as is, just seeing lots of discussion about it in various threads here and was wondering if it's on your radar.

Keep up the good work, it's much appreciated! :D

[Nexus 7 Android Development] keneth_c:
It doesn't always happen but it's been happening on and off.

It's happened twice in the last 4 days or so.

I could send you some kinda logs or whatever u need. You mentioned "dmesg"... Could you shed light on that? Or is it mentioned on Page 1. I'll have a look either ways and see what I can find.

Thanks :)

--
[Nexus 7 Android Development] sgt. meow:
dmesg is something you do in shell (in this case using adb from a PC) that tells what the kernel has been up to.

Try to do this when the device is in deep sleep and you try to wake it up
[Nexus 7 Android Development] keneth_c:
OK sounds good. Will give it a go. Can I PM you if need be?

Gonna do some reading now :)

I can't go into deep sleep while charging. It only happens with this kernel. Is this normal? Not a big deal, just takes longer to charge.

In recovery, mounting USB-OTG also works.

Should I sent you any logs?

[Nexus 7 Android Development] sgt. meow:
It seems as though I misread your last post. USB hostmode isn't supposed to work in Recovery; OTG mounting should work. The reason being recovery uses a different kernel (you can check by typing uname -a in the adb console/terminal emulator in recovery). Sorry for the wrong info.
[Nexus 7 Android Development] Maxr1998:
Sorry, then I also misread/misillustrated sth. Recovery shouldn't matter when it uses a different kernel, it all the time worked as it should. The thing is with this kernel I can't boot from USB when being in MultiRom Startup-Menu, the stick doesn't get any power (doesn't blink). This was working in original KOT49H kernel with kexec patch by Tasssadar. But his kernel doesn't support f2fs and it isn't as far as good as yours (of course, it's only stock)
