[Xen-devel] [PATCH v3 0/6] Fix PCI passthrough for HVM with stubdomain

[Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx>]

In this version, I add PHYSDEVOP_msi_msix_set_enable to allow stubdomain
enabling MSI after mapping it. This patch is rather RFC and probably will
need adjustments (see comments after commit message there), if physdevop will
be the way to go.

Changes in v2:
 - new "xen/x86: Allow stubdom access to irq created for msi" patch
 - applied review comments from v1
Changes is v3:
 - apply suggestions by Roger
 - add PHYSDEVOP_msi_msix_set_enable

Marek Marczykowski-Górecki (5):
  libxl: do not attach xen-pciback to HVM domain, if stubdomain is in use
  libxl: attach PCI device to qemu only after setting pciback/pcifront
  libxl: don't try to manipulate json config for stubdomain
  xen/x86: add PHYSDEVOP_msi_msix_set_enable
  tools/libxc: add wrapper for PHYSDEVOP_msi_msix_set_enable
