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
