Thanks!

Before sending the patch series I ran the pipeline:
  https://gitlab.com/xen-project/people/olkur/xen/-/pipelines/1711201897

And based on the source code of Qemu the support of AIA should be present from 7.0.0:
```
$ git tag --contains 28d8c281200f20a060c456c81fd1564f3d119fda
staging-mjt-test
trivial-patches-pull-request
v7.0.0
v7.0.0-rc0
v7.0.0-rc1
v7.0.0-rc2
v7.0.0-rc3
v7.0.0-rc4
v7.1.0
...
```

And in Xen's GitLab CI it is used 7.2.11:
```
$ CONTAINER_NO_PULL=1 CONTAINER=bookworm-riscv64 ./automation/scripts/containerize 
*** Launching container ...   
user@6a1d1f0077fe:/build$ qemu-system-riscv64 --version
