NAME
       kmem - mapped kernel memory interface

DESCRIPTION
       The kmem character special device provides access to mapped kernel memory.

       Byte  addresses	in  kmem  are equivalent to mapped kernel memory addresses.  References to unmapped or user space addresses will return an
       error. Write accesses to console or PAL memory or to memory protected against writes will also return an error.

RESTRICTIONS
       Because memory is read and written in aligned quadwords (eight contiguous bytes), writing fewer than all the bytes in an  aligned  quadword
       is a read-modify-write operation that is not protected against writes to the same quadword.

       Device registers are accessed as aligned quadwords through kmem.

       The kmem file is not available as a memory mapped file.

FILES
       /dev/kmem
