With Apple Silicon available to the masses, it's a good time to add support for driving its virtualization extensions from QEMU. This patch adds all necessary architecture specific code to get basic VMs working, including save/restore. Known limitations: - WFI handling is missing (follows in later patch) - No watchpoint/breakpoint support Signed-off-by: Alexander Graf <agraf@csgraf.de> Reviewed-by: Roman Bolshakov <r.bolshakov@yadro.com> Reviewed-by: Sergio Lopez <slp@redhat.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 20210916155404.86958-5-agraf@csgraf.de [PMM: added missing #include] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
OS X Hypervisor.framework support in QEMU
These sources (and ../hvf-all.c) are adapted from Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor) (last known location: https://github.com/veertuinc/vdhh) with some minor changes, the most significant of which were:
- Adapt to our current QEMU's
CPUStatestructure andaddress_space_rwAPI; many struct members have been moved around (emulated x86 state, xsave_buf) due to historical differences + QEMU needing to handle more emulation targets. - Removal of
apic_pageand hyperv-related functionality. - More relaxed use of
qemu_mutex_lock_iothread.
