Table 2-14 MSI-64 miscellaneous signals
|msi_translator_page||Input||The target page address of the GITS_TRANSLATER register. The MSI-64 Encapsulator does not support a msi_transalator_page value of 0.|
|msi64_translator_page||Input||The target address of the 64-bit GITS_TRANSLATER register. This page must be at a different location to the msi_translator_page and at a location known only to the hypervisor. The hypervisor must be able to project the page from accesses from devices and processors that can spoof incorrect DeviceIDs.|
|awdeviceid||Input||The ACE-Lite AW sideband signal that reports the DeviceID for writes to GITS_TRANSLATER. The value is ignored for non-MSI writes.|
