* hvf: Introduce hvf vcpu structAlexander Graf2021-06-031-31/+31
| | | | | | | | | | | | | | | We will need more than a single field for hvf going forward. To keep the global vcpu struct uncluttered, let's allocate a special hvf vcpu struct, similar to how hax does it.

* hvf: remove TSC synchronization code because it isn't fully completeCameron Esfahani2019-11-261-3/+0Star
| | | | | | | | | | | The existing code in QEMU's HVF support to attempt to synchronize TSC across multiple cores is not sufficient. TSC value on other cores can go backwards. Until implementation is fixed, remove calls to hv_vm_sync_tsc(). Pass through TSC to guest OS.
