Assume there is a memory instruction and it is going to load something. An address is generated and I want to record that. At application level, the address is virtual, but the at the end of the day, there should be a physical address for cache/memory lookup. I found this topic, but...
There are multiple methods of translating the returned virtual address from mmap to the physical address. Using a physical memory region and supplying the physical address when posting requests improve the random access performance since no conversion from a virtual address to a physical address is ne...
Cached Physical Memory—kseg0 When address bits 31:29 contain 100,access is directed to physical memory through the cache. If the addressed location is not in the cache, bits 28:0 are placed on the system bus as a physical memory address, and the data presented by memory or a device is...

directly. By the way, not sure about Windows, but under Linux only 1 Mb of physical address space is available, because it may contain some service low-level data like BIOS tables. Access to other physical memory may corrupt virtual memory, managed by the OS, and that's why it's not ...
The IOMMU_MAP_PHYSICAL_ADDRESS_TYPE enum indicates the format of the physical address described in an IOMMU_MAP_PHYSICAL_ADDRESS structure.
Physical Address, also calledMAC address(media access control address) is a memory address that is represented in the form of a binary number on the address bus circuitry in order to enable the data bus to access a particular storage cell of main memory. ...
When Paging is enabled, the page tables are used to translate linear address to physical address. On the Other Hand, Physical Address is nothing but, the address value that appears on pins of processor during a memory read/memory write operations. ...
