Sounds great. It'd be nicer if there is a branch to try :)

Thanks

Yes, I have something on top of this series that enables the accelerated
support.  I need do a bit more testing and then will send out that as an
RFC v3. Hopefully later this week.

Thanks,

Hi Shameer,

Thank you for the effort and the work here.

A separate topic: do you have any preparation for the vIOMMU uAPI
patches (iommufd backends) in QEMU?

I think it should be the next step after this series, so I wonder
if you have done some worked already to test this series.

And maybe I can start that review process in parallel, or we will
have to wait for the vSMMU code.

Thanks
Nicolin
