[PATCH 0/8] hvf: Implement Apple Silicon Support
Posted by Alexander Graf 3 years, 4 months ago 
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 rudimentary, first version to get the ball
going on that. With this applied, I can successfully run both Linux and
Windows as guests, albeit with a few caveats:

  * no WFI emulation, a vCPU always uses 100%
  * vtimer handling is a bit hacky
  * we handle most sysregs flying blindly, just returning 0
  * XHCI breaks in OVMF, works in Linux+Windows

Despite those drawbacks, it's still an exciting place to start playing
with the power of Apple Silicon.

Enjoy!

Alex

This seems to conflict with the accel cleanup work being done by
Claudio[1].  Maybe Claudio could cherry-pick some of the code
movement patches from this series, or this series could be
rebased on top of his.

It seems easier for Claudio to cherry-pick patch 2/8
of this series ("hvf: Move common code out") and rebase
on top.

Claudio's series is still tagged RFC, but if you were
planing to queue it, you could take patch 2/8 out of
this series, as it is generic, and let the HVF/AA64
specific bits still being discussed.
