From dd56040d297a0c530e204e9f459b256e3ddd7e8f Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Mon, 29 Jul 2019 17:29:03 +0100 Subject: Revert "hw: report invalid disable-legacy|modern usage for virtio-1-only devs" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit f2784eed306449c3d04a71a05ed6463b8289aedf since that accidentally removes the PCIe capabilities from virtio devices because virtio_pci_dc_realize is called before the new 'mode' flag is set.
