MK808B KitKat kernel [Working WiFi & BT]

[BalintBanyasz]

I think I've managed to solve the high cpu usage issue

I had to modify dhd_linux.c to use polling instead of interrupts. The cpu usage looks normal.
I'll make a release this weekend. Stay tuned.

Wow! Thank you so much!

Here's the WiFi fix:

It contains the new kernel and a modified boot image. Tested with Dumonde's KitKat ROM.

Thank you so much. Finally someone did it. You're awesome. I'll try it with other rom and will report how it works.

Only bad thing is Rockchip's new Kodi isn't supported on RK3066, only on RK3288 & RK3368 devices and the firmware for RK3066 devices has been abandoned for about a year by Rockchip.

Use the link from post #153. That's the 1080p version.

Here is the patch for dhd_linux.c that solves the problem with high CPU usage.
Apply it and rebuild any kernel you like

Yes, that's my patch from my GitHub repository. Feel free to use it

You can find the the fixed kernels that I've built if you read the last few posts (#153 - 1080p kernel, #157 - 720p). You'll also need to flash the modified boot image, otherwise wifi won't work.
