[PATCH v2 0/5] hvf: stability fixes for HVF |
Date: |

The following patches fix stability issues with running QEMU on Apple
Hypervisor Framework (HVF):
- non-RAM, non-ROMD areas need to trap so accesses can be correctly
emulated.
- Current TSC synchronization implementation is insufficient: when
running with more than 1 core, TSC values can go backwards. Until
a correct implementation can be written, remove calls to
hv_vm_sync_tsc(). Pass through TSC to guest OS.
- Fix REX emulation in relation to legacy prefixes.
- More correctly match SDM when setting CR0 and PDPTE registers.
- Save away exception type as well as vector in hvf_store_events() so
they can be correctly reinjected in hvf_inject_interrupts(). Under
heavy loads, exceptions got misrouted.
Changes in v2:
- Fix code style errors.
Cameron Esfahani (5):
hvf: non-RAM, non-ROMD memory ranges are now correctly mapped in
hvf: remove TSC synchronization code because it isn't fully complete
hvf: correctly handle REX prefix in relation to legacy prefixes
hvf: more accurately match SDM when setting CR0 and PDPTE registers
hvf: save away type as well as vector so we can reinject them
