[KERNEL][AOSP/TW][27 Dec] War Kernel r3 // colder than ever

[Galaxtus]

Nope, huge memory leaks were caused by the r2p4 driver which was designed for ICS.

I'm currently working on it. There are a lot of barriers here, but I got Hardkernel and Insignal kernel sources which are already using r3p2, and am integrating these drivers into the CyanogenMod kernel. Got them compiling, that's a good start. I also got the Insignal blobs, but libUMP.so is missing. It should be compilable from source though.

There are a lot of great guys there, particulary Turl, hno, ssvc and rz2k from #linux-sunxi who have already dealed with Mali drivers. Also I get some useful answers from @codeworkx even though he doesn't care anymore.

Where were you all these days :victory: You are full of Gold :highfive:

Drivers shipped with NX Kernel were working fine. What version are they?

r3p1, just as the stock CM kernel.

EDIT: some progress, it is bootlooping but i know why http://paste.debian.net/27491/

 

[M3TALLICA]

Is it possible to under volt using only Tegrak Ultimate or you guys have undervolted using setcpu , voltage control etc ?
Unfortunately setcpu and voltage don't show voltage options.

Thanks.
I'm using a stock exynos4 CM Kernel from june and it's stable. No freeze at all.

Can you gently release a stable version (voltages?!?) of your fast kernel before spending time on new features?

Thanks and sorry if i seem unpolite but i don't meant to be.

Ok, expect it really soon.

Announcing Raw Kernel r3

Some users were complaining about r2's instability, so here comes r3!

Changelog :
* Restored GPU thresholds to values from XXLSZ. No yo-yo anymore! This change is part of the two commits I pushed to CyanogenMod.
* Restored GPU voltages to stock values (+50mV). As the kernel is using 134/200/266Mhz steps instead of 167/266MHz, it is actually still undervolted.

This should resolve all the problems encountered so far.

Download :
* raw_kernel_r3_cm101.zip
* raw_kernel_r3_cm102.zip

Soon, mali r3p2 goodness. :fingers-crossed:

 

[yokonunz]

Thanks. I report you back if some issues persist.

Please, add 400 mhz gpu step and 1600 mhz cpu. My phone is too laggy with default values because of many apps installed.
P.S and these values are really will do no harm, it was tested for a long time with NX kernel

What about this?

Freezed again!

I don't know what happening. Cm kernel is stable, NX was stable.

The phone starts heavily to lag and after some seconds it freezes.

Same here on r3.

works great on 4.3 pac though i cant install tegrak for undervolting

I asked codeworkx about this a few days ago, and he said that it was a mistake, he was talking about r2p4.

@yokonunz @grim00

Crap... apply +50mV on all CPU steps with Tegrak and report back.

I haven't go tegrak. Any alternatives?

I don't know any other free alternative

It seems your phone doesn't support undervolting at all, which is embarrassing.

 

[yokonunz]

I used to undervolt with NX.. Never had problems.
Can you try to fast compile a kernel with stock voltage table just for test the stability if it's not a big work?
Thanks

It's not the uv the cause, i have tested with +100 mv for gpu and +50 mv for cpu and today is happened the same, the phone become slow and sometimes definitively freeze.
I am thinking it's a rom issue, i am on rootbox rom, sure it's not voltage related.

Yokonunz check the pm

i used it with 4.2 rootbox and had no issues , using it with PAC 4.3 and facing no issues now too except for the stupid xposed thingy related to 4.3 roms
