Kitkat Kernels for All (well most!)

[marko33]

Just used the overclockomatic_kk script to overclock the AP2610t kernel to 1604, works ok but only have 3 steps for frequency now, is this normal.

It is normal for the tool. The author, PHJAnderson, coded it that way to reflect the fact that, unlike in tablets, there is no need to conserve power. Scaling is much quicker with fewer steps.

If you want the full compliment then just amend script.

My cx 919ii has a rk3188T cpu. Is it possible to overclock the ram or are they locked? Im only able to overclock the cpu nothing else

Nice one D33, thanks for your work on kernels, running smooth.

My kernels are CPU and DDR RAM 'unlocked'. You can check the DDR used in the DMESG log if you want confirmation

got some audio problems with ap6210t v2 kernel, sound is distorted.

crash+ HDMI zoom (HD)

Hi,
I have a few problems with the new kernels.

my modded tv stick worked with V1 kernels
but with the V2, it crashes a lot
also the HDMI zoom feature seems to be not working and the screen is 3% to big to fi on my panny tv !

ciao

No matter if i flash this

test-kernel-j22_cpu1608h_gpustock_ddrstock or
test-kernel-j22_cpu1608h_gpustock_ddr720.img

Im always getting the same antutu score thats why i have asked. Normally the antutu score should be higher with a overclocked ram. Am i right?

I have the same problem.

Wierd. Did you check DMESG to ensure the RAM speeds are different? The DDR changes wait states at 533 and 667 and so the stock will be quicker to repond but with lower bandwidth. THe 720 clock will have higher bandwidth but slower response. The net effect is generally positive to around 720, above that the latency increases decrease overall performance despite the increase in bandwidth.

Hi d33

Can you make kernels from Omegamoon's new 3.0.101 source for devices on JB?

https://github.com/omegamoon/Rockchip-GPL-Kernel

It has support for building mali drivers not the already binary compiled ones.
It supports more wifi drivers.
It includes loads of fixes/improvements that aren't available in the KitKat sources.

Thanks

No, i will do it now, 2 times. 1st with a stock kernel and the 2nd with a overclocked one. I can upload them if u wish. It would be nice if u take a look at, ur the pro im just a noob.

Just search for "ddrfreq:"

eg

ddrfreq: normal 528MHz video 0MHz video_low 0MHz dualview 0MHz idle 0MHz suspend 198MHz reboot 222MHz

Ok, found that sentence in test-kernel-j22_cpu1608h_gpustock_ddrstock.img. Now i will flash the oc kernel.

Found also a sentence: ddrfreq: change freq to 445 mhz when normal. Whats the meaning of?
Antutu scores about 17800.

In the overclocked kernel test-kernel-j22_cpu1608h_gpustock_ddr720.img,
i found ddrfreq: normal 720MHz video 0MHz video_low 0MHz dualview 0MHz idle 0MHz suspend 198MHz reboot 222MHz
Antutu scores about 18000

I gained only 200points, thats really weak. Should it be more?

My antutu scores 19200. The question why is my score so low? Its exactly the same as yours.
