2.3.146. VA2PA

Converts a virtual address to a physical address.

Syntax

VA2PA [,force][,table] address

where:

force

Force the conversion even if the attempt:

  • has an effect on cache

  • has an effect on memory

  • temporarily disables the MMU.

This is required on processors that lack the CP15 conversion registers.

table

Perform the conversion, even if the MMU is turned off (disabled).

This is unavailable on processors where the conversion is performed using CP15 registers.

address

The virtual address that is to be converted.

Description

The VA2PA command converts a virtual address into a physical address, and displays the physical address of a given virtual address. It is available on processors with an MMU subject to limitations. The MMU must be enabled.

Note

Using the VA2PA command on OS-aware connections does not give details for the current thread shown in the Code window. Instead, the results are for the processor in general. Also, a warning message is displayed.

Examples

The following example shows how to use VA2PA:

va2pa,f 0x10002000

This attempts to convert the virtual address 0x10002000 into a physical address.
