From f03d8ea330d69f3a98093dfa2633635dff355f90 Mon Sep 17 00:00:00 2001 From: Marcel Apfelbaum Date: Mon, 20 Feb 2017 22:43:10 +0200 Subject: hw/pcie: fix Extended Configuration Space for devices with no Extended Capabilities Absence of any Extended Capabilities is required to be indicated by an Extended Capability header with a Capability ID of 0000h, a Capability Version of 0h, and a Next Capability Offset of 000h. Instead of inserting a 'NULL' capability is simpler to mark the start of the Extended Configuration Space as read-only to achieve the same behaviour.
