Subject: [PATCH v6 00/11] hvf: Implement Apple Silicon Support
Date: Wed, 20 Jan 2021 23:44:33 +0100	[thread overview]
Message-ID: <20210120224444.71840-1-agraf@csgraf.de> (raw)

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)

Enjoy!

Alex

v1 -> v2:

  - New patch: hvf: Actually set SIG_IPI mask
  - New patch: hvf: Introduce hvf vcpu struct
  - New patch: hvf: arm: Mark CPU as dirty on reset
  - Removed patch: hw/arm/virt: Disable highmem when on hypervisor.framework
  - Removed patch: arm: Synchronize CPU on PSCI on
  - Fix build on 32bit arm
  - Merge vcpu kick function patch into ARM enablement
  - Implement WFI handling (allows vCPUs to sleep)
  - 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

v2 -> v3:

  - Removed patch: hvf: Actually set SIG_IPI mask
  - New patch: hvf: arm: Add support for GICv3
  - New patch: hvf: arm: Implement -cpu host
  - Advance PC on SMC
  - Use cp list interface for sysreg syncs
  - Do not set current_cpu
  - Fix sysreg isread mask
  - Move sysreg handling to functions
  - Remove WFI logic again
  - Revert to global iothread locking

v3 -> v4:

  - Removed patch: hvf: arm: Mark CPU as dirty on reset
  - New patch: hvf: Simplify post reset/init/loadvm hooks
  - 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
