   SYNOPSIS
     mach [-m | -c -[xd] | -o]

   DESCRIPTION
     This command displays data specific to a machine type.

       -m  Display the physical memory map (x86, x86_64 and ia64 only).
       -c  Display each cpu's cpuinfo structure (x86, x86_64 and ia64 only).
           Display each cpu's x8664_pda structure (x86_64 only),
           Display the hwrpb_struct, and each cpu's percpu_struct (alpha only).
       -x  override default output format with hexadecimal format.
       -d  override default output format with decimal format.
       -o  Display the OPAL console log (ppc64 only).
