Using Mali on Linux for MarsBoard

all credit goes to olegk0 and linux-sunxi community.

I just tried olegk0's code and introduce about it. don't ask olegk0 about any error in this page, he is not responsible for anything written in here.

prepare

toolchain

 git clone -b android-4.4.2_r1 https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6 prebuilts/gcc/linux-x86/arm/arm-eabi-4.6

this is official toolchain to build Android for Rockchip. you may use another toolchain which is known to work with your kernel source.

kernel source

 wget http://www.haoyuelectronics.com/service/RK3066/Images/linux-3.0.36-source-code/marsboard-linux-rockchip.tar.gz

this is up-to-date kernel source from Rockchip, but only drm.ko is needed. you may use your kernel source.

mali source

 git clone -b r3p2-01rel2-olegk0 https://github.com/linux-rockchip/mali-modules.git

this is (currently) r3p2-01rel2 source code from ARM + minimal rk30 support code taken from olegk0's repository.

build kernel modules

drm.ko

 cd /path/to/rockchip-3.0
 make ARCH=arm marsboard_rk3066_px2_hdmi_defconfig
 make Image
 make EXTRA_CFLAGS="-D__linux__" M=drivers/gpu/drm

drivers/gpu/drm/drm.ko will be built.
