2021-09-21hvf: arm: Implement PSCI handlingAlexander Graf
We need to handle PSCI calls. Most of the TCG code works for us, but we can simplify it to only handle aa64 mode and we need to handle SUSPEND differently. This patch takes the TCG code as template and duplicates it in HVF. To tell the guest that we support PSCI 0.2 now, update the check in arm_cpu_initfn() as well.

2021-09-20hvf: Add Apple Silicon supportAlexander Graf
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>
