invd

Invalidate the processor's internal caches.

Syntax

[[px]] invd

Where:

[px]

is the viewpoint override, including punctuation ( [ ] ), specifying that the viewpoint is temporarily set to processor x of the boundary scan chain.  The processor can be specified as px (where x is the processor ID), or an alias you have defined for a given processor ID.  ALL cannot be used as a viewpoint override.

Discussion

Use the invd command to invalidate the processor's internal caches. Data held in internal caches is not written back to main memory.  In a multiprocessor system, only the caches for the current viewpoint are invalidated. The invd command can only be used when the target is stopped.

Examples

To invalidate P2's internal caches:

Command input:
