Banana Pro GPU加速（1）-GPU驅動移植安裝

本來想用Banana Pro來看電影發現卡的不行，CPU佔用率過高，因此從網上找到了香蕉派GPU加速的教程，總結一下！主要參考文獻  http://wiki.lemaker.org/BananaPro/Pi:GPU，bananapi cookbook，但是裏面給出的教程缺少了一些必要的細節導致安裝時破費周折。
1.打開shell 建立文件夾

$ mkdir ~/video_acceleration
$ cd ~/video_acceleration

2.下載所需要的驅動源碼

$ git clone https://github.com/robclark/libdri2.git
$ git clone https://github.com/linux-sunxi/libump.git
$ git clone https://github.com/linux-sunxi/sunxi-mali.git
$ git clone https://github.com/ssvb/xf86-video-fbturbo.git
$ git clone https://github.com/linux-sunxi/libvdpau-sunxi.git
$ git clone https://github.com/linux-sunxi/libcedrus.git
$ git clone git://anongit.freedesktop.org/vdpau/libvdpau

這裏要注意
libvdpau-sunxi依賴於   
libvdpau >= 1.1   
libcedrus (https://github.com/linux-sunxi/libcedrus)   
pixman (http://www.pixman.org)

3.安裝必要的包

$ sudo apt-get install libvdpau-dev xorg-dev \
    dh-autoreconf xutils-dev libdrm-dev \
    libegl1-mesa-dev libgles2-mesa-dev

4.編譯安裝libdir2

$ cd ~/video_acceleration/libdri2
$ ./autogen.sh --prefix=/usr
$ sudo make install

5.編譯安裝libump

$ cd ~/video_acceleration/libump
$ autoreconf -vi
$ ./configure --prefix=/usr
$ make
$ sudo make install

6.編譯安裝libvpdau

$ cd ~/video_acceleration/libvpdau
$ ./autogen.sh
$ make
$ sudo make install

7.編譯安裝libcedrus

$ cd /usr/local/include/
$ sudo mkdir credus

如果沒有創建這個文件夾，安裝時會報錯！

$ cd ~/video_acceleration/libcredus

$ make
$ sudo make install

8.編譯安裝pixman

$ tar -xzvf pixman-0.34.0.tar.gz
$ cd pixman-0.34.0/
$ ./configure
$ make 
$ sudo make install  

9.安裝編譯sunxi-mali

$ cd ~/video_acceleration/sunxi-mali
$ git submodule init
$ git submodule update
$ sudo mkdir /usr/lib/mali
$ make config ABI=armhf VERSION=r3p0
$ sudo make -C include install
$ sudo make -C lib/mali prefix=/usr/ libdir='/usr/lib/mali/'install

10.建立鏈接

$ sudo -s
# echo "/usr/lib/mali" > /etc/ld.so.conf.d/1-mali.conf
# ldconfig
# exit

11.安裝編譯fbturbo

$ cd ~/video_acceleration/xf86-video-fbturbo
$ autoreconf -vi
$ ./configure --prefix=/usr
$ make
$ sudo make install

12.配置fbturbo

sudo nano /etc/X11/xorg.conf
Section "Screen"
        Identifier      "My Screen"
        Device          "Allwinner A10/A13 FBDEV"
        Monitor         "My Monitor"
EndSection
Section "Device"
        Identifier      "Allwinner A10/A13 FBDEV"
        Driver          "fbturbo"
        Option          "fbdev" "/dev/fb0"
        Option          "SwapbuffersWait" "true"
        Option          "AccelMethod" "G2D"
EndSection
Section "Monitor"
        Identifier      "My Monitor"
        Option          "DPMS" "false"
EndSection

13.配置設備的使用權限

$ sudo nano /etc/udev/rules.d/50-mali.rules

14.安裝編譯libvpdau-sunxi

$ cd ~/video_acceleration/libvdpau-sunxi
$ make
$ sudo make install

15.設置環境變量

$ sudo -s
# echo "export VDPAU_DRIVER=sunxi" >> /etc/profile

並且把當前登錄用戶加入video組

sudo usermod -aG video $USER

16.重啓後檢驗安裝效果

grep -i fbturbo /var/log/Xorg.0.log

會出現下圖安裝成功~！！

接下來就可以通過源碼編譯mplayer或VLC來添加GPU加速播放高清視頻了~~
