Hey Alex and Paolo,
I saw there is some code related to AVX
https://elixir.bootlin.com/linux/latest/source/arch/x86/kvm/emulate.c#L668
Does that mean in some special cases, kvm supports AVX instructions ?
I didn’t really know the big picture, so just guess what it is doing .
Thanks,
Xu

vmovdqu .
I am curious about how kvm emulates those instructions. Do you mind sharing
some related code pointer ?
Thanks,
Xu

2. I write an emulated PCI device for QEMU, and run my programs on the
