Series

xen-arm: add support for virtio-pci | expand

Message

Volodymyr Babchuk Dec. 2, 2023, 1:41 a.m. UTC

Hello,

This patch series adds the basic support for virtio-pci for xen-arm
guests. The main changes are in "xen_arm: Add virtual PCIe host bridge
support", while most of other patches are required to make QEMU work
as device model in a non-privileged domains like driver domain.

New in version 4:
 - Patch "xen: decouple generic xen code from legacy backends codebase"
   is factored out from "xen: add option to disable legacy backends"
 - Updated patch "xen: backends: don't overwrite XenStore nodes created
   by toolstack" (see the patch description)

New in version 3:

 - Use commandline/properties instead of xenstore entries to configure
   PCIe bridge
 - Instead of trying to fix legacy backends, just add option to disable
   them


David Woodhouse (1):
  hw/xen: Set XenBackendInstance in the XenDevice before realizing it

Oleksandr Tyshchenko (2):
  xen_arm: set mc->max_cpus to GUEST_MAX_VCPUS
  xen_arm: Add virtual PCIe host bridge support

Volodymyr Babchuk (3):
  xen: backends: don't overwrite XenStore nodes created by toolstack
  xen: decouple generic xen code from legacy backends codebase
  xen: add option to disable legacy backends
