PHYS_TO_KSEG(9r)
NAME
  PHYS_TO_KSEG - General: Converts a physical address to a kernel-unmapped
  virtual address

SYNOPSIS
  vm_offset_t PHYS_TO_KSEG(
	  vm_offset_t addr );

ARGUMENTS
  addr
      Specifies the physical address to convert to a kernel-unmapped virtual
      address.

DESCRIPTION
  The PHYS_TO_KSEG routine converts a kernel physical address to a kernel-
  unmapped virtual address.

EXAMPLE
  The following code fragment shows a call to PHYS_TO_KSEG:

       .
       .
       .

       caddr_t virt_addr;  [1]
       unsigned phys_addr; [2]

       .
       .
       .

	       virt_addr = PHYS_TO_KSEG(phys_addr); [3]

       .
       .
       .

   1.  Declares a variable to store the virtual address returned by
       PHYS_TO_KSEG.

   2.  Declares a variable to store the physical address. This address might
       have been obtained from a call to KSEG_TO_PHYS.

   3.  Calls PHYS_TO_KSEG to convert the physical address to a corresponding
       virtual address.

RETURN VALUES
  Upon successful completion, PHYS_TO_KSEG returns the virtual address
  associated with the specified physical address.
