NAME
pmap_extract, pmap_extract_and_hold -- map a virtual address to a physical page SYNOPSIS
#include <sys/param.h> #include <vm/vm.h> #include <vm/pmap.h> vm_paddr_t pmap_extract(pmap_t pmap, vm_offset_t va); vm_paddr_t pmap_extract_and_hold(pmap_t pmap, vm_offset_t va, vm_prot_t prot); DESCRIPTION
The pmap_extract() function maps a virtual address to a physical page. In certain situations, callers may use pmap_extract_and_hold() instead, to ensure that the returned page is held. The pmap_extract_and_hold() function maps a virtual address to a physical page, and atomically holds the returned page for use by the caller, only if the mapping permits the given page protection. IMPLEMENTATION NOTES
Currently, the page protection requested by the caller is not verified. RETURN VALUES
The pmap_extract() function will return the physical page address associated with the virtual address va inside the physical map pmap. If the mapping does not exist, or if the pmap parameter is NULL, then NULL will be returned. The pmap_extract_and_hold() function will return the physical page address associated with the virtual address va inside the physical map pmap. If the mapping does not exist, the result is a no-op, and NULL will be returned. SEE ALSO
