[Xen-devel] [PATCH v7 0/4] Fix PCI passthrough for HVM with stubdomain

[Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx>]

In this version, I drop PHYSDEVOP_interrupt_control patch, since Jan prefer not
to mix pciif and hypercalls for serving device model. Enabling MSI by the
stubdomain remains unsolved here, but other patches are improvement anyway.

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
Changes in v4:
 - implement suggestions by Wei, Roger, Jan
 - plug new physdevop into XSM
Changes in v5:
 - rebase on master
 - rename to PHYSDEVOP_msi_control
 - move granting access to IRQ into create_irq
Changes in v6:
 - simplify granting IRQ access, record dm domid for cleanup
 - rename to PHYSDEVOP_interrupt_control
 - include INTx control in the hypercall
Changes in v7:
 - update "xen/x86: Allow stubdom access to irq created for msi"
 - drop "xen/x86: add PHYSDEVOP_interrupt_control"
 - drop "tools/libxc: add wrapper for PHYSDEVOP_interrupt_control"

Marek Marczykowski-Górecki (4):
  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: Allow stubdom access to irq created for msi.
