[Xen-devel] [PATCH v3 6/7] vpci/msix: carve p2m hole for MSIX MMIO regions

2018-10-30 Thread Roger Pau Monne
Make sure the MSIX MMIO regions don't have p2m entries setup, so that accesses to them trap into the hypervisor and can be handled by vpci. This is a side-effect of commit 042678762 for PVH Dom0, which added mappings for all the reserved regions into the Dom0 p2m. Signed-off-by: Roger Pau Monné
