Ext4 of 3.11 is more optimised than 3.0. It will be the best if we can Backport ext4 3.11. Do you know if there is a Backport?

[Samsung Galaxy Nexus] boype:
Backporting ext4 from 3.11 should be possible. Back porting f2fs is not giving us anything at the moment, as far as I can comprehend: the ROMs / recoveries would have to be built for f2fs. Someone correct me if I'm wrong.

Also: where did you read about ext4 improvements?
[Samsung Galaxy Nexus] SoftWord:
So you plan to backporting ext4?

I'll see how much work / difficult it is. If I need to modify many parts of the core block subsystem and other filesystems too, I won't do it. If it is mostly about modifying only ext4, I'll try.

On phoronix I've see many benchmark and ext4 of 3.11 is fastest fs that now can have.

bigmem problems

i have a very special problem with the bigmem implementation, maybe you have never experienced.

first of all, you should know that some branch of maguro (especially the gsm branch) is very sensitive to humidity (moist). In rainy days like we have here now it's quite common that the camera goes off and the services connected to camera (and to gallery !) stop as well. if it happens at (re)boot, the camera does not even start and the whole system boots in a quite unstable state. it is clearly indicated by the extreme consumption. i guess, it is a "simple" contact error at the camera fitting/connector, but i haven't dared to dismantle the device because of the guarantee. (anyway, i met this problem with other phone models, too, here around !)

if it happens with this kernel (or with any other implementing this bigmem model), the system does not even boot but just rolls the boot logo endlessly. i just guess, but it may be the same problem with the camera start-up. after several attempts i've concluded that the system can be (re)booted only by dirty re-flashing the whole rom. (which is a big no-no in the rushy workday mornings ;).

so, may i ask for implementing the bigmem model into a kernel branch separate from the ext version. as this is the best kernel ever i've just tried on my maguro, i don't want to loose it. but i definitely need the ext features, especially the sound extension (otherwise i miss most of my calls and notifications at work or at travelling).

thank you

[Samsung Galaxy Nexus] d0ge01:
Wow.. never heard this problem before :o

Are you sure? using cover don't prevent this?

i used my phone in place where's humidity is like 100% ( night on beach ) and never suffer this issue , only issue releated to humidity that i suffer is screen become unusable when there's droplets in screen

[Samsung Galaxy Nexus] xzilem:
Do you use Slim AIO gapps or Slim Minimal gapps? Can you try another gapps?
[Samsung Galaxy Nexus] _yaz_:
sure. just make a quick search here on xda for "camera/gallery stopped...". but the net is full of such complaints, too.

the cover of (my) maguro is just a weak plastic crap. on the other hand, an air tight cover would be even worse (imho).

however, there are some reports on the net that tighting the camera connector heals the problem but i must collect some more courage. dismantling this device needs some brutal strechy steps i'd rather not try ;)

yep, droplets kill all the touchscreens but this humidity problem affects only some devices. u're lucky with ur model ;)

I'll continue to report it for as long as bigmem breaks any of my apps that access the camera. I'm running CM10.2, I first test without Fancy and they work. I add Fancy with bigmem and it breaks. Back on Fancy std without bigmem and everything is fine again.

So trolling, no, but testing and reporting back real results, yes.

I appreciate that this doesn't happen to everyone and wouldn't want the option dropped, but to assume that for those that it does break are trolls is offensive.

Fancy Updater - Update

First of all sorry for my disappearing. I was busy with school and so on. So in this version I fixed mostly all bugs. Hopefully the next update will bring the option to tweak this awesome kernel. I'm also thinking about an option to switch between both "channels" (std and ext).

Short changelog:

- detects if fancy is installed or not

- detects if you're on a test build (won't annoy you to update/test versions are unsupported at the moment)

- new logo/design (credits go to [MENTION=4681991]DaNi_![/MENTION])

- a few improvements under the hood

- download shows the version number

- you can see the installed version and the latest version

- settings

- [..]

Please report bugs! I'd like to fix all bugs and thank you for all your support! I also want to thank [MENTION=4615478]boype[/MENTION] for his awesome kernel!! :)

[Samsung Galaxy Nexus] Citizen_Snips:
I have to say, I wasn't convinced about these extra RAM kernels, like, at all... The first time I tried one I couldn't watch HD YouTube videos, Netflix wouldn't load any video at all, certain apps force closed, etc.

I'm running the latest test version over PA 3.99.1 RC1. All the applications I mentioned above work flawlessly. YouTube plays in HD, Netflix works fine... Everything seems to work. I think you found your "sane compromise" boype. :)

I agree the fun stops when apps fail, but I should of known if any kernel dev here could add it and make it stable, it would be you. you:cool:

Anyways great job. 0 issues so far. Great idle drain overnight too.
[Samsung Galaxy Nexus] Technical:
Thanks for the work in this kernel.

The ondemandplus governor, the presence of powersave one, the stability, etc. made me move from Franco Kernel to Fancy.

The updater is much better now (maybe it can detect and work only on wifi).

r42 up

Hi again,

r42 is ready for you. The change log is self-explanatory:

update to Linux 3.0.96

split up extended version and BIGMEM for a seperate BIGMEM ('big') version. The big version is like the ext one, but with additional BIGMEM.

HUGEMEM: rename to BIGMEM and add 8 MB to HEAP_TILER again ('only' 65 MB of additional available RAM now, but apps shouldn't crash anymore)

mm: remove compressed copy from zram in-memory (less wasted zram)

ext4: Speed up FITRIM by recording flags in ext4_group_info (the automatic periodic trimming performed by Android will be way faster by keeping track of blocks that need to be trimmed)

ARM: implement optimized percpu variable access (picked from mpokwsths' repo; small performance improvement for some workloads)

ondemandplus governor: re-add the adaptive timer_rate logic (sorry for back and forth ;) )

RAMdisk: fix root issues on some ROMs (I simply forgot to add two command lines last time when updating the RAMdisk)

RAMdisk: still disable 1080p recording with BIGMEM-enabled kernels, BUT also put an init.d script in place, which will automatically re-add the 1080p modes when another kernel is installed

Have fun :good:

[edit] regarding RAMdisk: still disable 1080p recording with BIGMEM-enabled kernels, BUT also put an init.d script in place, which will automatically re-add the 1080p modes when another kernel is installed

I have to add the following: This mechanism fails if you had r41 or pre42-1 installed. There are three different solutions (by performing ONE of them, you're all good):

1) Dirty-flashing your ROM

2) Copy /sbin/bigmemcheck to /system/etc/init.d/62bigmemcheck and set permissions to rwxr-xr-x (755)

3) In case there is a file named /system/etc/media_profiles.xml.bak present, delete /system/etc/media_profiles.xml and rename /system/etc/media_profiles.xml.bak to /system/etc/media_profiles.xml

My intention with ondemandplus is a good compromise between responsiveness and power savings. In comparison, interactive is a little more suitable for performance and a little less suitable for battery life. Opinions and experiences may vary, of course.

Twrp already supports it for moto x. If fancy supports it, advanced users may be able to use fastboot to covert data and/or cache to f2fs without recovery and when recovery supports it, we'll be ready for it:) I could be wrong, as I am no dev. but if possible, I'll try it.

UPDATE TO MY SITUATION:

It's not bigmem after all. I'm mistaken. Wrong.

Today, I flashed new version of Slim AIO and Gapps -- with pre-release bigmm 42, same problem.

But then flashed Franco, after Osmosis kernel reset script -- and still got same problem.

So, it's NOT bigmem issue. Something else.

Others are having problems with bigmem, but my issue of LED with barcode scanner does not seem to be related -- at least with pre-release 42.

[Samsung Galaxy Nexus] akash3656:
Previous implementation of HUGEMEM used to break DicePlayer for me but the built in video player from the Gallery works. Once the player crashed, the camera also doesn't work.

Now with r42-big, DicePlayer works but with a slight delay. But its quite a minor thing, so I'm not too worried.

Edit: Spoke too soon, it seems to still crash after a few times of playing videos especially if you change the orientation of the phone while it's loading the video.

I cannot play x264 encoded video with MX player in HW or HW+ mode with the big mem version of r42.

i constantly use MX player. there were issues at first on 4.3 when released.

I've been staying away from using the HW+ decoder tho and have had zero issues since.

might try again if i feel like finding and grabbing one of the custom codecs for it.

i had used one before and it had made MX just behave way better at the time. been a while tho since i did that.
