[Qemu-devel] [PATCH v4 0/3] Make KVM/MSI code device-ID-aware

[Pavel Fedin <p.fedin@samsung.com>]

On ARM architecture ITS (Interrupt Translation Service), additionally to
normal MSI data, uses also side-band device IDs. This series prepares the
infrastructure to handling them.

This small series is actually an extraction from vITS support RFC
(https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg07074.html).
Nobody reviewed it so far, however some bits of it could actually be
applied early. This series consists only of those parts, which do not
depend on any new unreleased kernel APIs.

v3 => v4:
- Rename msi_requester_id() to pci_requester_id() and move from MSI to PCI
  code

v2 => v3:
- Use official "requester ID" denotion everywhere. Renamed getter function
  and MemTxAttrs field.

v1 => v2:
- Improved commit messages, more explanations
- msi_device_id() function made architecture-specific

Pavel Fedin (3):
  kvm: Make KVM_CAP_SIGNAL_MSI globally available
  hw/pci: Introduce pci_requester_id()
  kvm: Pass PCI device pointer to MSI routing functions
