+.Sh NAME
+.Nm uvm_km_suballoc
+.Nd raw kernel memory or address space allocator
+.Sh SYNOPSIS
+.In sys/param.h
+.In uvm/uvm.h
+.Fn uvm_km_suballoc "vm_map_t map" "vaddr_t *min" "vaddr_t *max " "vsize_t size" "int flags" "boolean_t fixed" "vm_map_t submap"
+.Sh DESCRIPTION
+The
+.Fn uvm_km_suballoc
+function allocates submap (with the specified
+.Fa flags ,
+as described above) from
+.Fa map ,
+creating a new map if
+.Fa submap
+is
+.Dv NULL .
+The addresses of the submap can be specified exactly by setting the
+.Fa fixed
+argument to non-zero, which causes the
+.Fa min
+argument to specify the beginning of the address in the submap.
+If
+.Fa fixed
+is zero, any address of size
+.Fa size
+will be allocated from
+.Fa map
+and the start and end addresses returned in
+.Fa min
+and
+.Fa max .
