Can I use the vmm files found on the FreeBSD source code under the dir "vmm" to accelerate qemu on the Radxa Zero 3W / arm64 ?

Hello to everyone,

Today looking at the FreeBSD source code for ARM64,I saw these files :

I have no idea where these files come from and how much good they are. But can I use them for accelerate qemu with vmm ? or for what ?

Where are those files and what do they have to do with Qemu? I think this is bhyve part.

ok,but for doing what ? is it bhyve for arm64 ? I never used it yet. I don't have a piece of hardware fully compatible with gicv3. I ask because there is a pending project that accellerate qemu with vmm. I wonder if those files can be useful for achieving that goal.

It seems to be supported by Qemu now. What does

Code:

qemu-system-x86_64 -accel help

say after loading the vmm module? It should recognize vmm as available accellerator.
I'm curious about what this improves.
