VTAG(1prom)         RISC/os Reference Manual          VTAG(1prom)



NAME
     vtag - determine the virtual tag for a cache location

SYNOPSIS
     vtag [-c cpu_number] address

AVAILABILITY
     This command is available only on RC6380 systems.

DESCRIPTION
     vtag is a PROM monitor or standalone shell (sash(1M)) com-
     mand that attempts to derive the virtual tag for a cache
     location. address specifies a word in the secondary cache
     and must be between 0x0 and 0x3fffc.  cpu_number specifies
     the CPU cache to use. If you do not specify cpu_number, the
     master CPU's cache is used (the master is the only CPU on
     single-processor computers).

     Use this command for debug or maintenance purposes.
