[Qemu-devel] [PATCH] hw/pci/pci-stub: Add msi_enabled() and msi_notify()

From: Thomas Huth
Subject: [Qemu-devel] [PATCH] hw/pci/pci-stub: Add msi_enabled() and msi_notify() to the pci stubs
Date: Tue, 19 Feb 2019 17:07:39 +0100

Some machines have an AHCI adapter, but no PCI. To be able to
compile hw/ide/ahci.c without CONFIG_PCI, we still need the two
functions msi_enabled() and msi_notify() for linking.
This is required for the upcoming Kconfig-like build system, if
a user wants to compile a QEMU binary with just one machine that
has AHCI, but no PCI, like the ARM "cubieboard" for example.
