From b166b8ab4189743a717cb93f50d6fcca3a46770d Mon Sep 17 00:00:00 2001 From: Jiqian Chen Date: Tue, 24 Sep 2024 14:14:36 +0800 Subject: xen/pvh: Setup gsi for passthrough device In PVH dom0, the gsis don't get registered, but the gsi of a passthrough device must be configured for it to be able to be mapped into a domU. When assigning a device to passthrough, proactively setup the gsi of the device during that process.
