[PATCH v8 00/19] hvf: Implement Apple Silicon Support

[Alexander Graf <agraf@csgraf.de>]

Now that Apple Silicon is widely available, people are obviously excited
to try and run virtualized workloads on them, such as Linux and Windows.

This patch set implements a fully functional version to get the ball
going on that. With this applied, I can successfully run both Linux and
Windows as guests. I am not aware of any limitations specific to
Hypervisor.framework apart from:

  - Live migration / savevm
  - gdbstub debugging (SP register)
  - missing GICv3 support


Enjoy!

Alex

  - Synchronize system registers (fixes OVMF crashes and reboot)
  - Don't always call cpu_synchronize_state()
  - Use more fine grained iothread locking
  - Populate aa64mmfr0 from hardware
  - Make safe to ctrl-C entitlement application

  - Remove i386-softmmu target (meson.build for hvf target)
  - Combine both if statements (PSCI)
  - Use hv.h instead of Hypervisor.h for 10.15 compat
  - Remove manual inclusion of Hypervisor.h in common .c files
  - No longer include Hypervisor.h in arm hvf .c files
  - Remove unused exe_full variable
  - Reuse exe_name variable

v4 -> v5:

  - Use g_free() on destroy

v5 -> v6:

  - Switch SYSREG() macro order to the same as asm intrinsics

v6 -> v7:

  - Already merged: hvf: Add hypervisor entitlement to output binaries
  - Already merged: hvf: x86: Remove unused definitions
  - Patch split: hvf: Move common code out
    -> hvf: Move assert_hvf_ok() into common directory
    -> hvf: Move vcpu thread functions into common directory
    -> hvf: Move cpu functions into common directory
    -> hvf: Move hvf internal definitions into common header
    -> hvf: Make hvf_set_phys_mem() static
    -> hvf: Remove use of hv_uvaddr_t and hv_gpaddr_t
    -> hvf: Split out common code on vcpu init and destroy
    -> hvf: Use cpu_synchronize_state()
    -> hvf: Make synchronize functions static
    -> hvf: Remove hvf-accel-ops.h
  - New patch: hvf: arm: Implement PSCI handling
  - New patch: arm: Enable Windows 10 trusted SMCCC boot call
  - New patch: hvf: arm: Handle Windows 10 SMC call
  - Removed patch: "arm: Set PSCI to 0.2 for HVF" (included above)
  - Removed patch: "hvf: arm: Add support for GICv3" (deferred to later)
  - Remove osdep.h include from hvf_int.h
  - Synchronize SIMD registers as well
  - Prepend 0x for hex values
  - Convert DPRINTF to trace points
  - Use main event loop (fixes gdbstub issues)
  - Remove PSCI support, inject UDEF on HVC/SMC
  - Change vtimer logic to look at ctl.istatus for vtimer mask sync
  - Add kick callback again (fixes remote CPU notification)
  - Move function define to own header
  - Do not propagate SVE features for HVF
  - Remove stray whitespace change
  - Verify that EL0 and EL1 do not allow AArch32 mode
  - Only probe host CPU features once
  - Move WFI into function
  - Improve comment wording
  - Simplify HVF matching logic in meson build file

v7 -> v8:

  - checkpatch fixes
  - Do not advance for HVC, PC is already updated by hvf
    (fixes Linux boot)
