+.Sh NAME
+.Nm pmap_map
+.Nd map a physical memory range into kernel virtual address (KVA) space
+.Sh SYNOPSIS
+.In sys/param.h
+.In vm/vm.h
+.In vm/pmap.h
+.Ft vm_offset_t
+.Fo pmap_map
+.Fa "vm_offset_t *virt" "vm_paddr_t start" "vm_paddr_t end" "int prot"
+.Fc
+.Sh DESCRIPTION
+The
+.Fn pmap_map
+function maps a range of physical addresses into kernel virtual address (KVA)
+space, from
+.Fa start
+to
+.Fa end ,
+with protection bits
+.Fa prot .
+.Pp
+The value passed in
+.Fa *virt
+is treated as a hint for the virtual address of the beginning of the mapping.
+.Sh IMPLEMENTATION NOTES
+The
+.Fa prot
+argument is currently ignored by machine-dependent implementations.
+.Pp
+Architectures which can support a direct mapped physical to virtual
+region can return the appropriate address within that region, leaving
+.Fa *virt
+unchanged.
+.Sh RETURN VALUES
+The
+.Fn pmap_map
+function returns the virtual address of the beginning of the mapping, if
+the mapping was successfully made;
+.Fa *virt
+will also be updated with the first usable address after the mapped region.
+.Pp
+If the function is unsuccessful,
+.Dv NULL
+is returned.
