[PATCH v3 0/4] MSI-X support with qemu in stubdomain, and other related changes

[Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx>]

This series includes changes to make MSI-X working with Linux stubdomain and
especially Intel Wifi 6 AX210 card. This takes care of remaining reasons for
QEMU to access /dev/mem, but also the Intel Wifi card violating spec by putting
some registers on the same page as the MSI-X table.

See individual patches for details.

Marek Marczykowski-Górecki (4):
  x86/msi: passthrough all MSI-X vector ctrl writes to device model
  tools/xendevicemodel: Introduce ..._get_ioreq_server_info_ext
  x86/hvm: Allow writes to registers on the same page as MSI-X table
  x86/msi: clear initial MSI-X state on boot
