From 882877fc359d24e1563065c5c3887096317ca1ae Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Fri, 14 Oct 2022 16:10:45 +0100 Subject: hw/pci-bridge/cxl-upstream: Add a CDAT table access DOE This Data Object Exchange Mailbox allows software to query the latency and bandwidth between ports on the switch. For now only provide information on routes between the upstream port and each downstream port (not p2p). Signed-off-by: Jonathan Cameron -- Changes since v8: Mostly to match the type 3 equivalent - Move enum out of function and give it a more descriptive namespace.
