From dba95ebbf88a8b8f10f4691946b4406e4acc4f0f Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Tue, 25 Jul 2017 19:59:18 +0200 Subject: [PATCH] spapr_pci: parent the MSI memory region to the PHB This memory region should be owned by the PHB. This ensures the PHB cannot be finalized as long as the the region is guest visible, or used by a CPU or a device.
