bp_mapin
bp_mapin(9F) Kernel Functions for Drivers bp_mapin(9F)NAME
bp_mapin - allocate virtual address space
SYNOPSIS
#include <sys/types.h>
#include <sys/buf.h>
void bp_mapin(struct buf *bp);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
bp Pointer to the buffer header structure.
DESCRIPTION
bp_mapin() is used to map virtual address space to a page list maintained by the buffer header during a paged- I/O request. bp_mapin()
allocates system virtual address space, maps that space to the page list, and returns the starting address of the space in the
bp->b_un.b_addr field of the buf(9S) structure. Virtual address space is then deallocated using the bp_mapout(9F) function.
If a null page list is encountered, bp_mapin() returns without allocating space and no mapping is performed.
CONTEXT
bp_mapin() can be called from user and kernel contexts.
