Thanks for your reply. We are testing vSVA, and will let you know if
other problems are found.

Found a problem here, the cmd for guest stage 1 invalidation is built,
but it is not delivered to smmu.
Thank you for the report. I will fix that soon. With that fixed, have
you been able to run vSVA on top of the series. Do you need other stuff
to be fixed at SMMU level? As I am going to respin soon, please let me
know what is the best branch to rebase to alleviate your integration.
Best Regards
Eric
