KVM QEMU AIA support for RISCV guests

KVM QEMU AIA support for RISCV guests

[Rajnesh Kanwal]

Hi All,

I am starting to work on KVM-QEMU AIA support for RISCV guests to extend
kvm accel support added in [0]. This is just to confirm if anyone else
is actively
working on it to avoid duplicate effort.

Thanks,
Rajnesh

I was going to look into it eventually, but now that you've started I'll sit
back and help with reviews and testing and so on.


Thanks,

Daniel

Hi Rajnesh and Daniel,

Recently, I implemented a series of QEMU v7.2-based patches for
KVM-AIA and tested them on the QEMU riscv-virt machine. I plan to
refine the patches and upstream them soon.

Thanks,
Yong-Xuan

Hi Rajnesh and Daniel,

Recently, Yong-Xuan (yongxang.wang@sifive.com) has already implemented
a series of QEMU v7.2-based patches for KVM-AIA and tested them on the
QEMU riscv-virt machine.
She plans to refine the patches and upstream them soon.

Thanks,
Jim Shu

Hi Youn-Xuan and Jim,

Thanks, that sounds great. Actually I am working on a PoC of CoVE
support in QEMU which requires AIA support.

I will wait for you to post the patches. Meanwhile It would be very
helpful if you can share the code if it's in a public fork. I can start
my work on top of that.

Thanks
Rajnesh
