[libvirt] [PATCH v2 0/2] Block assignment of PCI devices below non-ACS capable switch

This is a patchset for blocking assignment of PCI devices below non-ACS capable switch. In case user still wants to assign such device even though it might not be safe, she can specify 'relaxed_acs_check = 1' in qemu.conf Special thanks to Chris L. who created a standalone program the PCI check. This code is a port of that check to libvirt. Changes in version 2: - permissive attribute for <hostdev> was removed - new 'relaxed_acs_check' config option in qemu.conf for relaxing the check Jiri Denemark (2): Tests for ACS in PCIe switches Use pciDeviceIsAssignable in qemu driver src/libvirt_private.syms | 1 + src/qemu/libvirtd_qemu.aug | 1 + src/qemu/qemu.conf | 6 ++ src/qemu/qemu_conf.c | 4 + src/qemu/qemu_conf.h | 2 + src/qemu/qemu_driver.c | 6 ++- src/qemu/test_libvirtd_qemu.aug | 6 ++- src/util/pci.c | 151 +++++++++++++++++++++++++++++++++++++++ src/util/pci.h | 4 + 9 files changed, 179 insertions(+), 2 deletions(-)
