[PATCH 0/2] arm/hvf: Add SME2 support

Posted by Manos Pitsidianakis 3 weeks, 2 days ago

M4/M5 Macs support SME2, and HVF exposes this functionality in its
public API.

Add support for it in QEMU.

This was tested by running an SME2 benchmark from Arm [0]. savevm and
loadvm during the benchmark's run were used to verify migration works.

For this series:

Reviewed-by: Mohamed Mediouni <mohamed@unpredictable.fr>

Random note: For running on older macOS releases when built with a new SDK, you might also need -weak_framework, but not sure meson supports that…
