定义一个“label:”来引用Node,在编译是系统会自动为node生成一个phandle属性。“cpu0"是一个label,用来引用node"cpu@0”: 代码语言:javascript 复制 cpu0:cpu@0{device_type="cpu";compatible="arm,cortex-a35";reg=<0x000>;enable-method="psci";cpu-idle-states=<&LEGACY_MCDI&LEGACY_SODI&LEGACY_SODI3...
(1)所有的cpu core属于一个inner shareable domain (2)所有的cpu core和dma controller属于一个outer shareable domain。(这个如果硬件不支持就没有) 在ARM architecture中,对一个normal memory location而言,是否是coherent是和它的页表中的shareability attribute的设定相关。
