The tr and tv subcommands can be used to display address translation information. The tr subcommand provides a short format; the tv subcommand a detailed format.
tr Address
tv Address
For the tv subcommand, all double hashed entries are dumped, when the entry matches the specified effective address, corresponding physical address and protections are displayed. Page protection (K and PP bits) is displayed according to the current segment register and machine state register values.
