[Xen-devel] [PATCH v2 0/4] Display IO topology when PXM data is available

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

Changes in v2:
* Split topology sysctls into two --- one for CPU topology and the other
  for devices
* Avoid long loops in the hypervisor by using continuations. (I am not
  particularly happy about using first_dev in the interface, suggestions
  for a better interface would be appreciated)
* Use proper libxl conventions for interfaces
* Avoid hypervisor stack corruption when copying PXM data from guest


4 patches that add interface for querying hypervisor about device
topology and allow 'xl info -n' display this information if PXM object
is provided by ACPI.

The patches are:

* Store PXM data (nodeID) in pci_dev during PHYSDEVOP_pci_device_add
  hypercall
* Modify XEN_SYSCTL_topologyinfo interface to make it a little more efficient.
  (This patch is not necessary for IO topology handling)
* Add XEN_SYSCTL_pcitopoinfo sysctl for querying hypervisor about
  device topology
* Make use of the above sysctl in libxl.


Boris Ostrovsky (4):
  pci: Do not ignore device's PXM information
  sysctl: Make XEN_SYSCTL_topologyinfo sysctl a little more efficient
  sysctl: Add sysctl interface for querying PCI topology
  libxl: Add interface for querying hypervisor about PCI topology
