PMAP_QENTER(9) BSD Kernel Developer's Manual PMAP_QENTER(9)NAME
pmap_qenter, pmap_qremove — manage temporary kernel space mappings
pmap_qenter(vm_offset_t sva, vm_page_t *m, int count);
pmap_qremove(vm_offset_t sva, int count);
The pmap_qenter() function accepts a linear array of count pointers to
wired pages *m, and enters each of these pages into the kernel virtual
address (KVA) space, beginning at the address sva.
The pmap_qremove() function tears out a mapping from the kernel virtual
address space, beginning at sva and for count pages.
The pmap_qenter() function is intended for temporary mappings that do not
require page modification or reference counting. Old mappings are simply
overwritten. The pages must be wired into physical memory.
The corresponding pmap_qremove() function is intended to remove such tem‐
