| description | Fast invalidation in peripheral component interconnect (PCI) express (PCIe) address translation services (ATS) initially utilize a fast invalidation request to alert endpoints that an address is being invalidated with a fast invalidation synchronization command that causes the endpoints to flush through any residual read/write commands associated with any invalidated address and delete any associated address entries in an address translation cache (ATC). Each endpoint may send a synchronization complete acknowledgement to the host. Further, a tag having an incrementing identifier for each invalidation request may be used to determine if an endpoint has missed an invalidation request. |
