Test OpenGL ES Linux support on Firefly-RK3288 Development Board
════════════════════════════════════════════════════════════════
Introduction
────────────
Firefly-RK3288 development board is equipped with the powerful Mali
T764 GPU. Lately, ARM has released the binary user-space fbdev
driver. We, the Firefly team, have taken a first stab at it.
Environment:
- Firefly-RK3288 development board with latest dual boot firmware
installed.
- 64 bit Ubuntu Linux (12.04 or later) host pc.
Kernel
──────
First, we need to update the mali kernel driver.
Download Linux kernel driver TX041-SW-99002-r5p1-00rel0.tgz in
[http://malideveloper.arm.com/develop-for-mali/drivers/open-source-mali-t6xx-gpu-kernel-device-drivers/]
The porting process involves: replace the old driver files with new
ones, apply the kds patch, fix the compiling errors and update the
config file.
To make life easier, we've packaged all the files into
firefly-mali-driver-TX011-SW-99002-r5p1-00rel0.tar.gz .
╭────
│ cd /path/to/your/firefly/sdk
│ ls kernel # kernel directory should be here
│ tar xzf /path/to/firefly-mali-driver-TX011-SW-99002-r5p1-00rel0.tar.gz
╰────
Then compile it:
╭────
│ cd kernel
│ make firefly-rk3288-linux_defconfig
│ make -j8 firefly-rk3288.img
│ make modules
╰────
The compiled mali module is located at drivers/gpu/arm/midgard/. Copy
mali_kbase.ko to your board:
╭────
│ scp drivers/gpu/arm/midgard/mali_kbase.ko root@BOARD_IP:/system/lib/modules/
╰────
(Why `/system/lib/modules/' ? Just because /etc/rc.local willl insmod
it automatically.)
Then follow the steps described in
[http://wiki.t-firefly.com/index.php/Firefly-RK3288/Build_kernel/en] ,
to pack zImage and initrd to linux-boot.img .
Flash linux-boot.img to recovery partition of the board.
User-space drivers
──────────────────
Download mali-t76x_r5p0-06rel0_linux_1+fbdev.tar.gz in:
[http://malideveloper.arm.com/develop-for-mali/features/mali-t6xx-gpu-user-space-drivers/]
Then install it to the board:
╭────
│ cat /path/to/mali-t76x_r5p0-06rel0_linux_1+fbdev.tar.gz \
│ | ssh root@BOARD_IP tar --strip-components=1 -xzf - -C /usr/lib
╰────
Compile Mali OpenGL ES SDK demos
────────────────────────────────
Download Mali_OpenGL_ES_SDK_v2.4.4.71fdbd_Linux_x64.tar.gz in
[http://malideveloper.arm.com/develop-for-mali/sdks/opengl-es-sdk-for-linux/]
Please choose Linux X64 archive.
To build the SDK demos, you need a cross compile toolchain. If you
have not installed yet, try this linaro toolchain:
[http://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz]
(Extract it to /opt)
You also need to install cmake (sudo apt-get install cmake).
╭────
│ tar xzf /path/to/Mali_OpenGL_ES_SDK_v2.4.4.71fdbd_Linux_x64.tar.gz
│ cd Mali_OpenGL_ES_SDK_v2.4.4
│ mkdir build-arm
│ cd build-arm
│ export TOOLCHAIN_ROOT=/opt/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-
│ cmake -DTARGET=arm ..
│ make install
│ cd ..
│ # bin_arm contains all the result files
│ scp -r bin_arm root@BOARD_IP:/root
╰────
Set 32bit framebuffer
─────────────────────
Before running demos, the fbdev should be in 32 bit mode.
Run following commands on the board:
╭────
│ sudo -s
│ cat << EOF >/etc/init/fbset.conf
│ # fbset - run fbset to set truecolor fbmo
│ description "run fbset before lightdm"
│ start on startup and started udev or starting lightdm
│ task
│ script
│ [ -x /bin/fbset ] && /bin/fbset -a -nonstd 1 -depth 32 -rgba "8/0,8/8,8/16,8/24"
│ end script
│ EOF
│ cat << EOF >/etc/X11/xorg.conf
│ Section "Screen"
│ Identifier "Default Screen"
│ DefaultDepth 24
│ EndSection
│ EOF
╰────
Then reboot the device.
Run demos
─────────
Before running demos, make sure you have:
1. Flashed the new Linux kernel.
2. Updated mali_kbase.ko
3. Installed Mali user drivers
4. Uploaded Mali demos
5. Configured 32bit framebuffer
Then open a terminal, run one of the demo:
╭────
│ sudo -i
│ cd bin_arm/opengles_30/skybox
│ ./skybox
╰────
Enjoy!
