修改启动文件,在内存分配有三种模式可选。 如果用不着XBMC,开机的时候64m用于3d加速
sudo cp /boot/arm192_start.elf /boot/start.elf 就行了
这时候内存:显存的分配为 192:64
sudo cp /boot/arm224_start.elf /boot/start.elf 只给显存保留最少32m使用,没有加速了.
这时候内存:显存的分配为 224:32
/Choosing the right ARM/GPU memory split
There is a choice of how the 256M of RAM is divided between the ARM and GPU:
arm224_start.elf : 224M ARM, 32M GPU split : Maximum ARM memory. Good for ARM desktop use. No accelerated video or 3D possible.
arm192_start.elf : 192M ARM, 64M GPU split : Reasonable ARM memory. Simple video (omxplayer) or 3D (quake) is possible. This is the default.
arm128_start.elf : 128M ARM, 128M GPU split : Use this for heavy 3D work, or 3D plus video. Needed for XBMC.
