Devicetree动态解析器说明
|
||
========================
|
||
|
||
本文描述了内核内DeviceTree解析器的实现，它位于drivers/of/resolver.c中。
|
||
|
||
解析器如何工作？
|
||
----------------
|
||
|
||
解析器被赋予一个任意的树作为输入，该树用适当的dtc选项编译，并有一个/plugin/标签。这就产
|
||
生了适当的__fixups__和__local_fixups__节点。
|
||
|
||
解析器依次通过以下步骤工作:
|
||
|
||
1. 从实时树中获取最大的设备树phandle值 + 1.
|
||
2. 调整树的所有本地 phandles，以解决这个量。
|
||
3. 使用 __local__fixups__ 节点信息以相同的量调整所有本地引用。
|
||
4. 对于__fixups__节点中的每个属性，找到它在实时树中引用的节点。这是用来标记该节点的标签。
|
||
5. 检索fixup的目标的phandle。
|
||
6. 对于属性中的每个fixup，找到节点:属性:偏移的位置，并用phandle值替换它。
