NAME    [Toc]    [Back]

     pmap_pinit, pmap_pinit0, pmap_pinit2 -- initialize pmap structures

SYNOPSIS    [Toc]    [Back]

     #include <sys/param.h>
     #include <vm/vm.h>
     #include <vm/pmap.h>

     void
     pmap_pinit(pmap_t pmap);

     void
     pmap_pinit0(pmap_t pm);

     void
     pmap_pinit2(pmap_t pmap);

DESCRIPTION    [Toc]    [Back]

     The pmap_pinit() function initializes the preallocated and zeroed structure
 pmap, such as one in a vmspace structure.

     The pmap_pinit0() function initializes the physical map pm, associated
     with process 0, the first process created in the system.

     The pmap_pinit2() function wires in kernel global address entries for the
     physical map pmap, which must be associated with a user process.  It is
     called during process creation.

     To avoid a race condition between pmap intialization and
     pmap_growkernel(), pmap_pinit2() should be called after the vmspace is
     attached to the process but before this pmap is activated.

IMPLEMENTATION NOTES    [Toc]    [Back]

     The pmap_pinit2() function has been deprecated, and should be implemented
     as a stub until further notice.
