Macro Definition Documentation

#define X86_64_MEM_PAGE_MASK 0x1fffff

Mask for physical memory page

#define X86_64_MEM_PAGE_SIZE X86_64_LARGE_PAGE_SIZE

Physical memory page size is 2 MBytes

#define X86_64_PDIR_ENTRIES ( limit ) (X86_64_PDPT_BASE((limit) - 1) + 1)

Resolves to required number of entries in page directory to map 'limit' number of bytes.

#define X86_64_PDPT_ENTRIES ( limit ) (X86_64_PML4_BASE((limit) - 1) + 1)

Resolves to required number of entries in page directory pointer table to map 'limit' number of bytes.

#define X86_64_PTABLE_ENTRIES ( limit ) (X86_64_PDIR_BASE((limit) - 1) + 1)

Resolves to required number of entries in page table to map 'limit' number of bytes.
