From ec7dd52fe3754a13ea2565fab38247081ce7be9f Mon Sep 17 00:00:00 2001 From: Sasha Levin Date: Wed, 5 Mar 2014 23:08:16 -0500 Subject: [PATCH] kvm tools: mark our PCI card as PIO and MMIO able A recent -next patch named "PCI: Ignore BAR contents when firmware left decoding disabled" has pointed out that PCI cards are supposed to declare that they have either PIO or MMIO BARs by disabling them if it didn't. Fix it by correctly marking our emulated PCI card as PIO/MMIO enabled.
