i am having some battery issue with the latest version of carbon (i did a clean install and used the kernel in the rom zip file), i heard this kernel is good on the battery, can i just flash it on top of the rom or should i re-install everything from scratch ?
[Xperia Arc Android Development] Antoniokodo:
You can flash on top of the rom, just do wipe cache and dalvik after flashing kernel and modules and you are good to go:good:
[Xperia Arc Android Development] touns_j:
already done , thanks for the reply though

nice kernel .. and booting little faster than LX one ...

-EDIT-

I have a problem with openGL when using fox browser!! is it kernel issue or app issue ?!

Any progress update about badass governor implementation?
[Xperia Arc Android Development] Dark Raven:
Not yet. I'm very busy for last times. :(

Is everything ok with latest build?
[Xperia Arc Android Development] DiamondJohn:
I have been using the kernel with the second latest build of Carbon ROM on an ST18a, and its been very good.

The weird thing (in a good way) is that before I flashed your Kernel, I was getting really bad Wifi transfer rates at home (ie around 1MBs). I am guessing I "broke" it somehow, and its not the ROM. When I flashed your Kernel, I was surprised I didn't have to flash the additional modules as well like previous times to get WiFi working (i was hoping that your Kernel and modules would "fix" my WiFi), but I also noticed that my WiFi was still poor, so I flashed them anyway to test it (I had a nandroid before I started). And low and behold, my WiFi jumped to 6MBs! :highfive:

Back on 1.8GHz OC and no noticeable reboots. With the last Carbon ROM build being so snappy, I really noticed the 1.8GHz OC compared to 1.4GHz. :D Thanks!
[Xperia Arc Android Development] Mardon:

[Xperia Arc Android Development] GaMeR77:
Bro, your kernel is awesome and I thanked you for that. You have also given wifi modules but I didn't need that. I need something that would fix my bluetooth like something bluetooth modules... I am using Carbon rom cm11 4.4.2... So can you fix it? I tried reflashing the rom and kernel but didnt work.. (╥_╥)
[Xperia Arc Android Development] DomusX10:
I'm on last CarbonRom for Arc S (25-3) and with last DarkKernel all goes well.

Thank you very much for this works!!!

I want to know a thing: which is the recommended I/O scheduler?

Because now I'm on CFQ....which are differences with

- ZEN

- DEADLINE

- SIO

- BFQ

??

Can someone tell me the features of these? Or tell me where can I read about it?
[Xperia Arc Android Development] DiamondJohn:
I'm running an Xperia Ray, It takes less than 30 seconds from the vibration when I hold the power button, to the start of the boot animation.

However, that's from a complete "cold" boot (ie unplugged from charger, and off for a bit), which I do not normally do. I turn my phone off every night, and put it on the charger, and then boot it in the morning while it is still plugged into the charger. If I am not mistaken, I think the Kernel is partially loaded under this state, and so the boot time of the Kernel is even less for me normally.

Try the search function

http://xdaforums.com/sitesearch.php?q=io scheduler

which includes this useful post:

http://xdaforums.com/showthread.php?t=1631894

Which includes the following:

I personally have used SIO, but am currently trialing ZEN (which if I understand correctly is a version built from SIO) actually ROW. I haven't noticed a difference between these two, yet.

However, this latest kernel has a "new" CPU governor called Adaptive which I am also trialing. Usually I use SmartAss or Interactive as they do not cause stuttering when the screen is off, and I am listening to music. However, this new Adaptive Governor also appears to perform as well, but when I look at the CPU history, it appears to have stayed at the lowest CPU frequency a LOT longer than I would expect to see with the other governors. You would expect this to mean better battery and longer CPU life, especially with a 1.8GHz OC. Any info (for interest purposes) on this governor is pretty thin on the ground.
[Xperia Arc Android Development] GaMeR77:
It works fine on Carbon rom and I love it. But it seems It doesn't work on Pacman rom or I did something wrong. So can you tell how to flash on pacman ROMs? I did factory reset and flashed the the kernel .. flashed the kernel than factory reset/wipe data and wipe cache .... flashed the kernel installed the rom than factory reset and wipe cache and wipe dalvic cache .. but didn't work ... so please help ...

[MENTION=5092317]Dark Raven[/MENTION] could i request you to build this kernel for xperia mini (st15i) too? (its supported by LX too.) because user feedback sounds great with your kernel :good: anyway if you cant or dont have enough time may i would try to do it myself, but then as far i know i need to patch the default LX kernel source of my device & then built it. but im confused how to. (i think adding stuff like your new govenors & I/O shedulers is not the problem, i could solve it myself. my problem is i dont know where to find the stuff/files to add into it.)

Once i faced Camcorder freeze that was maybe due to rom.

Overall Camera and camcorder wi-fi and Bluetooth are fine.

Hi all,

Does making an alternative kernel without video recording feature(if yields more ram by this way) take too much effort?

Because, after the ION stuff, available ram dropped drastically(~338 mb) and we can really feel the performance degrading, especially in browsers.

Or is there any other idea to increase the available ram?

thanks...
[Xperia Arc Android Development] Mardon:
Cant feel a bad change in performance with new ion kernel.

[Xperia Arc Android Development] datumdatzgr:
You are right. I use also ART and the speed is just awesome. However, low ram comes into picture at different scenarios, i think. Most important is the one that is browsing issue for me.

I am a bit asserting that we should seek a way to increase the ram available to user...

i will keep this setup (maybe flash new vanir nightly) for a day or two and then test overclocking.

Tried 18.5 dark kernel on Carbon Rom 23/04 build ,everything was ok except wifi, so flashed the module & wifi also working,

but now find out that video recording is not working at all(tried different settings)

so reverted back to carbon 23/04 zip included kernel,but now video recording is ok, but my wifi is gone, so plz help me what should i do?
[Xperia Arc Android Development] keen36:
18.5. dark kernel uses ion, and carbon rom still uses pmem. maybe that is why you are having problems? :confused:
[Xperia Arc Android Development] wasim9283:
But now what i should do to enable wifi again?
[Xperia Arc Android Development] keen36:
i am not sure if vishal had switched to ion kernel in between nightlys but i do not think so. you can try: make nandroid backup, flash previous dark kernel (20.3.), enter recovery, format /system, flash carbon rom 23.4., flash gapps if you want, format /cache, wipe dalvik cache, reboot.

edit:

man, i just read your previous posts again, are you saying that you are having the wifi problem while using carbon rom's included kernel? if so, why are you asking in this thread? :confused:

edit 2:

now i saw your post in the carbon rom thread :P
[Xperia Arc Android Development] wasim9283:
wao, you mean full flash again?

then i will switch to some other rom(for trial also)

One thing ,if i reflash the same rom(23/4 carbon) without wipes? can this help for wifi to come back?
[Xperia Arc Android Development] keen36:
full flash? you do not lose anything with that method, settings and apps all stay. however, if you switch roms, it is better to wipe everything.

if you flash the rom, it should wipe /system automatically, but maybe it doesn't, so just wipe it before you flash.

i misunderstood you at first, i thought you wanted to use dark kernel with carbon rom. if you want to use carbon's included kernel, just do exactly what i wrote above with that kernel.

i think we should move this discussion to the carbon rom thread, we are spamming this precious dev thread a little.

Try to Remove from /system/lib/modules all the files and reflash the zip from cwm but mount system partition alone(from mounts and storage)before flashing the zip to solve any mounting issues.

Actually i m ok with disabling video recording feature completely, if will give more ram. But i dont have linux media in order to accomplish this.
[Xperia Arc Android Development] giannhs_n:
Read LX logs guys

The kernel has approx 374 ram (go on teminal emulator and type free.) as and lx kernel plus there is no ram used by camera anymore, when camera is ide system has more memory to use about 40mb and when you use camera it takes it back again.

SO total ram is about 410mb WITH HD VIDEO(not enabled by difault)/CAMERA there is nothing about "more ram" anymore so do not spam about it

To sum up you have approx 410mb ram but system shows 365...

Bricked!

Due to wakelock issues of this kernel, i tried to reinstall the rom.

Any suggestion?

It happened after installing this kernel.
[Xperia Arc Android Development] giannhs_n:
i have wakelock issues too i tried everything with no effect(full wipe,reflash kernel and others..) ,reverted back to lx kernel

About fastboot issue try to flash stock kernel with flash mode, or try to remove battery insert battery again after add the wire + hold the fastboot button do not stop holding it until you flash the image and try to flash again..you can also change usb port maybe it will help
[Xperia Arc Android Development] datumdatzgr:
Removing battery trick does not help me. The notification led blinks once (while i press menu button at the same time connecting to pc). Then the phone switches on normally.

I cant enter fastboot or flash mode anymore. I think i will not be able to change this dark kernel anymore (battery lasts 10 hours on idle man,totally disappointment...). I am very sad...

EDIT: I had managed to enter fastboot mode once!

Happened with USB3.0 port via "adb reboot-bootloader" command.

Still, I am not getting into fastboot again...

I will inform you, thanks guys.

EDIT: I did it once again thru adb in recovery and flashed a stock kernel. Let me see the battery drain is due to kernel or some hw damage.

I am sure hw is damaged...

Hi [MENTION=1058330]DarkRaven[/MENTION]

Your work is really impressive and gives great results with CM11.

Developer mikeioannina is actually working on a 720p recording-enabled kernel build wich also gives user more available RAM (~412 MB).

It might be possible to pull up this limit and increase this RAM amount without loosing stability, isn't it ?

That would be wonderful if you could apply your magic on this future kernel (more RAM for userspace (?) + O/C [MENTION=4149147]1.8[/MENTION]GHz).

Moreover, like other users said, JustArchi's ArchiDroid Optimizations (GCC 4.8 toolchain + -O3 optimization flags) deeply enhance OS performance. I have tested it, and it works.

Link to official thread: http://xdaforums.com/showthread.php?t=2754997

I suggests you to implement these kernel-side optimizations in your next release.

With a ROM built with -O3 optimizations, the result would be really astonishing.

I don't think mikeioannina will do that as he aims at building pure CM ROMs.

Hope I helped.

Cheers.
