[Xen-devel] [PATCH v8 00/11] viridian: implement more enlightenments

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

This series adds three new enlightenments:

- Synthetic timers, which depends on the...
- Synthetic interrupt controller (or SynIC)
- Synthetic cluster IPI

All these enlightenments are implemented in current versions of QEMU/KVM
so this series closes the gap.

Paul Durrant (11):
  viridian: add init hooks
  viridian: separately allocate domain and vcpu structures
  viridian: use stack variables for viridian_vcpu and viridian_domain...
  viridian: make 'fields' struct anonymous...
  viridian: extend init/deinit hooks into synic and time modules
  viridian: add missing context save helpers into synic and time modules
  viridian: use viridian_map/unmap_guest_page() for reference tsc page
  viridian: stop directly calling
    viridian_time_ref_count_freeze/thaw()...
  viridian: add implementation of synthetic interrupt MSRs
  viridian: add implementation of synthetic timers
  viridian: add implementation of the HvSendSyntheticClusterIpi
