Changelo & To do list & Bugs:

Bugs

Please guys, this is a test build, it was tested on Carbon ROM and Resurrection Remix ROM,
but it has some stability issues, and you might face lots of bugs and software reboots while using it.

Will try to improve it, please give a nice feedback, and I'll enlist all bugs here.

To do list

• Add dual recovery support [No recoveries included anymore]
• Fix reboot to recovery in some ROMs [Done, I think!]
• Enable tap to wake feature [Impossible]

Changelog

2014-10-11:

2014-10-11:
Updated kernel with latest changes from CM & Pimped kernel

2014-05-30:

First here!!!! Great to see!!!! Already trying.

GPU OC in future update ?

GPU OC in future update ?

Maybe if I figure out why it isn't working, I mean GPU OC code is implemented in the kernel, but it's not working for some reason,
will see what I can do.

Yay! Finally! Cyanogen, here I come!
TY, mate. Was waiting for this for a loooooooong time. Good job pulling it off =)

I'm not even sure that GPU OC works properly on Z1...

I'm not sure about that ether, but the weird thing is that even though the same code (as the one used for Z1) is included here,
you can't even switch GPU to more that 450MHz, I mean the GPU script has all 487.5MHz / 533MHz / 600MHz OCs but they aren't showing up

 

[ctap001]

Tried it with pimp my z1

Didn't work. Specifically it crashes when any setting is changed from stock.

I'm on slimkat.

 

[zxqw]

Running it on the latest CM11 nightly (31/5) and the phone momentarily freezes very shortly after boot before rebooting. Can't say what triggers it because it happens regardless of what I do.

 

[idimitro]

Great work mate. The most important for me is the support for undervolting. Is it included in the kernel?

Yes it is, but you might find it buggy (for now)

 

[funiewski]

@omarainea I have tested (not so much but anyway...) with carbon and resurection roms. RR install was cleaner I hadn´t utilized kernel settings beforkrnel install. Kernel works good, no reboots have changed a lot of settings without problems, on carbon phone reboots all the time but I had changed a lot of settings before kernel install. Later I will try more clean carbon installation with pimpkernel, for now I´m going with RR rom. Great work, thanks!

Can you outline the steps you took? I can't get it to work on mine both with Carbon and Slim.

just did a clean Carbon or RR install, then boot to system, then reboot to recovery and flash the kernel without any wipes, reboot.

By clean you mean doing a factory reset prior?

And would it matter if I wipe partition and dalvik after flashing the kernel?

Also have you tried it with ART? My crashes only happen when I was on Dalvik

By clean install I mean factory reset and format /system prior, and it didn't matter to me whether I wipe dalvik after flashing the kernel or not.

also, now that you're mentioning it, I haven't tried ART on Pimped kernel yet (just Dalvik).

That step is always included in ROM instructions so I'm quite sure I did that. At first I thought the reboots were being caused by undervolting but even when I just changed the read-ahead in I/o settings I still get random crashes.

Hello!
Does the work kernel in the kit SlimRom? If so. I would like to test it!
thx

Nope kit SlimRom is Sony based not cm-based ROM, this kernel is for cm-based ROMs.

if you're looking for a custom kernel for kit SlimRom you can try DooMKernel, I'll release v19 soon, so wait for it and try it
