This patch addresses the same aspects on PPC the bug 1103314 addressed on x86. PCI expander bus creates multiple primary PCI busses, where each of these busses can be assigned a specific NUMA affinity, which, on x86 is advertised through ACPI on a per-bus basis. For SPAPR, a PHB's NUMA affinities are assigned on a per-PHB basis, and there is no mechanism for advertising NUMA affinities to a guest on a per-bus basis. So, even if qemu-ppc manages to get some sort of multi-bus topology working using PXB, there is no way to expose the affinities of these busses to the guest. It can only be exposed on a per-PHB/per-domain basis. So patch enables NUMA node tag in pci-root controller on PPC. The way to set the NUMA node is through the numa_node option of spapr-pci-host-bridge device. However for the implicit PHB, the only way to set the numa_node is from the -global option. The -global option applies to all the PHBs unless explicitly specified with the option on the respective PHB of CLI. The default PHB has the emulated devices only, so the patch prevents setting the NUMA node for the default PHB.

When looking for slots suitable for a PCI device, libvirt might need to add an extra PCI controller: for pSeries guests, we want that extra controller to be a PHB (pci-root) rather than a PCI bridge. Signed-off-by: NAndrea Bolognani <abologna@redhat.com> Reviewed-by: NLaine Stump <laine@laine.org>

PCI bus has to be numbered sequentially, and no index can be missing, so libvirt will fill in the blanks automatically for the user. Up until now, it has done so using either pci-bridge, for machine types based on legacy PCI, or pcie-root-port, for machine types based on PCI Express. Neither choice is good for pSeries guests, where PHBs (pci-root) should be used instead. Signed-off-by: NAndrea Bolognani <abologna@redhat.com> Reviewed-by: NLaine Stump <laine@laine.org>

These tests demonstrate that, while it's now possible for the user to create PHB explicitly and manually assign devices to them, libvirt still defaults to extending the guest PCI topology using PCI bridges and making suboptimal device placement choices. The next few commits will improve on these behaviors and the tests outputs will automatically be updated to reflect this.

Now that NVDIMM has found its way into libvirt, users might want to fine tune some settings for each module separately. One such setting is 'share=on|off' for the memory-backend-file object. This setting - just like its name suggest already - enables sharing the nvdimm module with other applications. Under the hood it controls whether qemu mmaps() the file as MAP_PRIVATE or MAP_SHARED. Yet again, we have such config knob in domain XML, but it's just an attribute to numa <cell/>. This does not give fine enough tuning on per-memdevice basis so we need to have the attribute for each device too. Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

NVDIMM is new type of memory introduced into QEMU 2.6. The idea is that we have a Non-Volatile memory module that keeps the data persistent across domain reboots. At the domain XML level, we already have some representation of 'dimm' modules. Long story short, NVDIMM will utilize the existing <memory/> element that lives under <devices/> by adding a new attribute 'nvdimm' to the existing @model and introduce a new <path/> element for <source/> while reusing other fields. The resulting XML would appear as: <memory model='nvdimm'> <source> <path>/tmp/nvdimm</path> </source> <target> <size unit='KiB'>523264</size> <node>0</node> </target> <address type='dimm' slot='0'/> </memory> So far, this is just a XML parser/formatter extension. QEMU driver implementation is in the next commit. For more info on NVDIMM visit the following web page: http://pmem.io/Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>
