Logical vs physical address 1) Anaddress generated by the CPUis a logical address. Whereas, anaddress seen by the memory unit, that is, the one loaded into the memory-address register of the memory, is aphysical address. 2) The user program never sees the physical addresses. The program ...
DMA操作前需要分配物理地址连续的一个Buffer,AllocateCommonBuffer函数提供了这个功能,该函数原型如下: PVOID AllocateCommonBuffer( _In_ PDMA_ADAPTER DmaAdapter, _In_ ULONG Length, _Out_ PPHYSICAL_ADDRESS LogicalAddress, _In_ BOOLEAN CacheEnabled ); 第三个参数有点不是很能理解,PPHYSICAL_ADDRESS Logical...
由此个人认为PPHYSICAL_ADDRESS LogicalAddress 这种定义只是微软命名习惯上的差异,这里的LogicalAddress就是物理地址而并非传统意义上的逻辑地址。

logical "abstraction layer" for dealing with the physical hardware. For example, virtual machines enable multiple operating systems to run in the computer, each accessing the hardware via a logic layer rather than direct physical contact.
