# pmap\_remove(9freebsd)

remove pages from a physical map

## NAME

**pmap\_remove**, **pmap\_remove\_all**, **pmap\_remove\_pages** – remove pages from a physical map

## SYNOPSIS

**#include \<sys/param.h\>**

**#include \<vm/vm.h\>**

**#include \<vm/pmap.h\>**

*void*\

**pmap\_remove**(*pmap\_t pmap*, *vm\_offset\_t sva*, *vm\_offset\_t eva*);

*void*\

**pmap\_remove\_all**(*vm\_page\_t m*);

*void*\

**pmap\_remove\_pages**(*pmap\_t pmap*);

## DESCRIPTION

The **pmap\_remove**() function removes the range of addresses between *sva* and *eva* from the physical map *pmap*. If *eva* is less than *sva*, then the result is undefined. It is assumed that both *sva* and *eva* are page-aligned addresses.

The **pmap\_remove\_all**() removes the physical page *m* from all physical maps in which it resides, and reflects back the modify bits to the appropriate pager.

The **pmap\_remove\_pages**() function removes all user pages from the physical map *pmap*. This function is called when a process exits to run down its address space more quickly than would be the case for calling **pmap\_remove**().

## SEE ALSO

**pmap**(*9*)
