Hi Guys, Xen currently doesn't map ECAM space specified in static ACPI table. Seeking opinion on how this should be handled properly. Each root complex ECAM region takes up 64K 4K pages (256MB). For some platforms there might be multiple root complexes. Is the plan to map all at once? Julien has mentioned support for mapping ECAM may come when support for PCI passthrough is added, is that right? What mechanism will it be? Will Xen or dom0 be the one that parses the staic ACPI tables and map the ECAM space?
