Hello, While trying to do some cleanup of the Xen interrupt support for pci pass though I came across the MSI to INTx translation that Xen is in theory capable of performing (ie: use a physical MSI interrupt source and inject that as an INTx to a guest).
AFAICT such functionality is not wired up to the toolstack, so it's hard to tell what's the indented purpose, or whether it has seen any usage. The commit that introduces it seems to be: 11f8ac5ebf passthrough: MSI-INTx translation for HVM Which contains your SoB. Could you elaborate a bit on what was the intended purpose, and whether this has never been used? Thanks, Roger.
