page table for the conversion between virtual addresses and physical addresses? On behalf of the above questions, let's look at the vmm-related boot code.
Find vmm content directly from the start_kernel () kernel boot section. We can see that the first function to be concerned is setup_arch (). In this function, the paging_init () function is used to initialize and map the hardware page table (8 MB of memory is mapped before initialization, the record is not recorded here), while paging_init ()
the accessed data is already in the physical memory, you must first convert the virtual address to the physical address, that is, "address ing", to truly access this data. This section describes how the Virtual Memory Manager maps virtual addresses to physical addresses in Win32.
Win32 uses a two-tier table structure to implement address ing. Because the 4 GB virtual address space is private to each process, each process maintains its own hierarchical table structure to implement address ing.
