Yeah..sorry..

There was a reason behind this..that most of developers dont come and answer in those sections....(or rare)..and this is something a developer could only answer (as others might not develop and wont know if its possible or can be tried).

Still i really apologies for that..its my frst and last thing..sorry..hope no body minds now :)..

[MENTION=5273865]xenon92[/MENTION]. Thought I'd test nebula v1.5 on RR v5.0.4 and take dmesg log immediately after reboot occurred. Hope it may help you. Should you require a different log like main kernel log just let me know. I'm using the app Sys log from the playstore, and assume it's providing useful information.

I am not working on this kernel anymore. Kernels aren't just interesting enough for me.
[Galaxy Grand Duos i9082 Android Development] Darian71:
Maybe someone else will attempt to build upon this then. Whatever you did has this kernel pushing my devices Ram speed (on benchmark anyways) in the 600's. No other kernel can, or has yet. Average is around 550 for others. And the 3D scores are awesome as well. Most certainly has potential. Who knows, maybe this summer, if I decide to take a break from school, I may dive into learning this code and cooking you guys do so well. If I'm lucky, maybe I can get the basics down within a month and begin building from source. ?

nebula kernel updated to v2.1.

- Started the kernel from scratch

- Using the latest Linaro 4.7.4 2014-04 build

- OC 1.4 Ghz, 1.5 Ghz, 1.6 Ghz

- Lowered swappiness from default 60 to 45

- Minor performance tweaks

---------

I started the kernel source from scratch and have added very few performance tweaks. I prefer calling this as a BETA build.

Only flash this kernel on SINGLE SIM AOSP ROMs and not on ROMs that support DUAL SIM.

I am using it on Resurrection Remix. But I don't use my phone for a lot of heavy stuff. That's why I uploaded it so that those of you who do, could do the testing with me and report back. All I want to know is - do you get random reboots?

Few things:

- Please use 1.2 Ghz for the testing phase of 1 or 2 days.

- Don't use Performance Control app for now. If you have it installed, uninstall it.

- Wipe cache and dalvik cache after flashing the kernel.

[MENTION=5273865]xenon92[/MENTION]

Still using O3 optimizations ?

Those were the main cause of reboots on Aki.Kernel.
[Galaxy Grand Duos i9082 Android Development] xenon92:
I removed the O3 optimization since v2.1. I think that was the culprit on my kernel too. I haven't got any reboots since removing that. But let's see. I am testing myself.
[Galaxy Grand Duos i9082 Android Development] jayc137:
Does nebula use AnyKernelUpdater ?

Ramdisk was the second culprit of (rare) random reboots and com.android.phone FCs on VanirAOSP and CM11.

I modified MoshKernel's zip file to use AnyKernelUpdater myself.
[Galaxy Grand Duos i9082 Android Development] xenon92:
That was happening because the ramdisk in those ROMs are modified to work with dual SIM support. That's why I mentioned to flash this on SINGLE SIM ROMs. The device tree used with Vanir ROM shouldn't have code of dual SIM support, which it does.

If all goes well and kernel seems to be stable, I'll add AnyKernel support too and it will work on both type of ROMs then, SINGLE as well as DUAL SIM ROMs.
[Galaxy Grand Duos i9082 Android Development] sharky.desire:

Updated nebula kernel to v2.2.

- Added support for ROMs that support dual-SIM (CM11)

- Added AnyKernel support (thanx to Koush, Apache14 and CoolDevelopment)

- Added Frandom

- Reduced Wi-Fi wakelocks by 4 times

-------

Since v2.2, the kernel can be flashed on any AOSP kitkat ROM, including CM11 that supports dual SIM (thanx to [MENTION=5706448]siddhu2199[/MENTION] for testing it on CM11). Not sure about CosmicCM though. Can't be sure until someone tests it.

That's good news. I haven't faced any problem too. That means only the "O3" optimization was messing with my kernel.

Now I'll add all the goodies that I added in v1.x slowly in v2.x+
[Galaxy Grand Duos i9082 Android Development] xenon92:
nebula kernel updated to v2.3.

- Added UKSM (enable it using Performance Control app) - link in OP

- Enforce governor to stay in sync across CPU cores

- Disables multicast on suspend (less wakelocks)

- Other performance tweaks
[Galaxy Grand Duos i9082 Android Development] xenon92:
nebula kernel updated to v2.4.

- Added I/O schedulers - SIO, ROW and VR

- Performance tweaks

-----

It will be hard to mention all the commits that I merge in my kernel in each release. You can check my Github (link in OP) for all the changes. I'll mention the most apparent changes and mention "Performance tweaks" for other changes.

From akiratoriyama's kernel thread I see that PegasusQ isn't stable. I'll add SmartassV2 and Lulzactive back to this one then.
[Galaxy Grand Duos i9082 Android Development] xenon92:
nebula kernel updated to v2.5.

[Galaxy Grand Duos i9082 Android Development] xenon92:
I test the kernels that I upload for at least a day before releasing them to check if everything is working fine. I don't use CosmicCM, ie. F2FS filesystem and hence I can't test it myself. Right now, I am working on the kernel for myself. So, I'll add F2FS support to this kernel after a few days and I'll release it as a test build, until someone confirms that it boots fine.
[Galaxy Grand Duos i9082 Android Development] xenon92:
nebula kernel updated to v2.6.

- Added a new governor - SmartassH3

- Added Dynamic FSync - Dynamic Sync Control (enable it in Performance Control)

nebula kernel updated to v2.7 - EXPERIMENTAL.

- Added F2FS support

------

There is no other change in this version. I have only added support for F2FS based ROMs (CosmicCM). Those of you who are on v2.6, no need to update as there is no change for you, but if you do update, kernel will work fine. See the screenshot that is attached on a ROM which isn't using F2FS.

This is an EXPERIMENTAL release as I don't use F2FS on my phone and hence can't test if the kernel boots fine or not. CosmicCM users, please report back if the kernel boots fine or not. The worst that could happen is a bootloop, which can be fixed by dirty flashing the ROM again or flashing a kernel that you know supports F2FS for sure.

------

By the way, I love the kernel too. :)

nebula kernel updated to 2.7.1 - EXPERIMENTAL.

---------

2.7.1 - EXPERIMENTAL contains more recent commits on F2FS. So it is an improvement from 2.7 - EXPERIMENTAL.

Please test both the EXPERIMENTAL versions and let me know if both boots fine or not. I'll not merge F2FS support into my main kernel branch until a few confirms that these boot fine on F2FS.

[MENTION=5273865]xenon92[/MENTION]

I faced a similar prob in my 2.0 kernel and that too only on Cosmic 3 F2FS. I had to mention deleting /system/libs/modules in my updater script.

Add this line after mounting system.

delete_recursive("/system/lib/modules");

Hope this helps ;)
[Galaxy Grand Duos i9082 Android Development] xenon92:
If that's so, could you try this [MENTION=5597025]Rahul111[/MENTION] -

1) From a root explorer, go to system/lib/modules and delete all the files in there (or move them to your SD card somewhere else)

2) Flash the kernel again

3) Try Wi-Fi

Please repeat these steps for both the versions. I am sorry that you have to do this testing, I would have done all this myself, but I don't use F2FS. I would prefer you try it on 2.7.1 first.

[MENTION=4830888]akiratoriyama[/MENTION] - I had that line in my previous updater script (before integrating AnyKernel). I'll add it back again.
[Galaxy Grand Duos i9082 Android Development] Rahul111:
tried this one also with both kernel versions ..but wifi is not enabling after deleting modules also..
[Galaxy Grand Duos i9082 Android Development] jayc137:
1) Copy all modules from kernel.zip/system/lib/modules to /system/lib/modules.

2) Set their permissions as rw-r-r.

I expect xenon92 to release the fixed kernel soon as his github has been updated hours ago.

governor / i/o schedular changes not sticking - 2.1.6

Tried changing the governor / io schedulers (via performance app) but it is not sticking.. gets reset back to ondemand/noop no matter what i do. Any clues what could be done ?

I am using 2.1.6 keenel version on RR v6.
[Galaxy Grand Duos i9082 Android Development] xenon92:
I think I found out what's wrong. But I'll need you to test it.

Follow these steps and let me know the result.

1) Delete all files from system/lib/modules using root explorer

2) Reboot into recovery

3) Flash either 2.7 or 2.7.1. Any one, it won't matter.

4) Let the phone reboot. Go into system/lib/modules and check if modules are there or not.

If you have already checked when the last time you followed the procedure, then let me know right away. If you didn't check back if the modules are there or not after flashing the kernel, please check this time and post here.

- I hope you mean v2.6 of nebula.

- Check that you've not disabled Performance Control app at boot time.

- Check that you've enabled Performance Control app's SET ON BOOT option

- Go to Settings - Performance and check if you have not selected SET ON BOOT option here. Untick SET ON BOOT here.
[Galaxy Grand Duos i9082 Android Development] Rahul111:
I have already checked this.. Modules were not there after that procedure..
[Galaxy Grand Duos i9082 Android Development] xenon92:
:)

That is good news. Thank you for testing.

I'll fix the issue in the next release.

To get back your modules, flash Aki kernel or reflash the ROM again.

[MENTION=4830888]akiratoriyama[/MENTION]

The problem is that in my updater script, while fixing modules, I mount the partition as ext4 and then try to move the modules from zip to the partition. This works fine on our NON-F2FS ROMs as they have their partitions as ext4 and WiFi and everything else works fine as modules copy without any problems, but not on F2FS partitions as the modules don't copy as the partition filesystem differs.

[MENTION=943196]k2wl[/MENTION]

You are using my AnyKernel port from my nebula kernel in your Evolution kernel. That's why WiFi isn't working on your F2FS ROMs too. There is nothing wrong with our kernels, just the updater script.

At least that seems to be the logical explanation that comes to my mind. I'll post a new build soon and I'll test this theory.
[Galaxy Grand Duos i9082 Android Development] xenon92:
Uploaded a new build.

nebula kernel v2.7.3 - EXPERIMENTAL
