Binary patched kernels for Pipo models

[stevejc]

Thanks,

I've got your script, just modify it, because M8HD find only one frequency for ddr.

I will try the kernel generated soon

here is my modified script : here

Edit :

Finaly, I think myscript is not working well, the FPS are awful compared to the original kernel.

This is what the modified script find :

== Table 8 at offset 10224340 ==
MHz mV
528 1250 256 DDR_FREQ_NORMAL

== Table 9 at offset 10224356 ==
MHz mV
200 950 1 DDR_FREQ_SUSPEND
460 1150 256 DDR_FREQ_NORMAL

== End of tables ==

What do you think about this ?

This is a factor of the KK kernel source now having two DDR tables; one if it detects t kernel (table 9) and the other for normal RK3188 (table 8).

OK I understand, but if I try to overclock table 8, it's worse than stock kernel, even if cpu goes to 1700.

Is there something I can do ?

With KitKat FPS are lower thant JB, even if KitKat seems smoother.
33 FPS in Epic Citadel compared to 444 in JB 4.2.2

I discovered the same. 37 fps in epic citadel compared to 44 on jb with my m7pro. But the smoothness of kit Kat is unbelievable, so i can waive the fps. I am no gamer, though. But the speed of the nand doubled compared to jb. You can check it with a1 sdbench...

Yes, same for me. It's really a pleasure.

It's why I will stay with KitKat now.

For kernel tuning, I see that if I try to patch DDR of table 8 (even with stock value ?) : it's worse.

So I can change the CPU, and change DDR of table 9 (this last change do nothing in fact, but CPU change and voltage too) and it's good for battery.

For performance : I get 20200 with CPU 1.7 compared to 19500 with stock Rom in Antutu

I would agree with you if the app worked suits or almost ... but for example does not work on sky go kit kat ... then the 3g is wrong, and only works in 2 g. In my opinion, a better room stable .... thanks anyway.

about 3g, the problem is not the rom but the libril file. If you use the stock libril (I've shared on the 1.8 thread) instead of the one installed by Riley on the Rom 1.8 you will have correct 3G functionality.

But no deep sleep anymore, right?

Giouncino, I'm thinking of a possible solution to screen flicker issues in the M8HD KitKat ROM's.

I'm wondering if you can get the kernel from my ROM and run patches for various GPU settings that users can try to find the sweet spot that might solve the issue.

Ok, I can give it a try. Please share only the kernel.img, in such a way I do not need to download the full ROM.
Thanks.

At the moment the answer is yes...unfortunately

I have posted the kernel of M8HD some posts above: http://www.freaktab.com/showthread.p...l=1#post156709

And the modified script that I'm trying to use here

But if you use a kernel mod, I force the connection in 2g, 3g how do I bring it back?

I don't understand what do you want to say...
Please explain it better

I'm sorry, but I do not speak English well. I'm Italian ..... I'd say that putting a kernel mod, I force the connection to 2g. I therefore fail to take advantage of the 3g ...
