Hi Julien:
Hello Lan,
Thanks for your input. This interface is just for virtual PCI device
which is called by Qemu. I am not familiar with ARM. Are there any
non-PCI emulated devices for arm in Qemu which need to be covered by
vIOMMU?
We don't use QEMU on ARM so far, so I guess it should be ok for now. ARM
guests are very similar to hvmlite/pvh. I got confused and thought this
design document was targeting pvh too.
BTW, in the design document you mention hvmlite/pvh. Does it mean you
plan to bring support of vIOMMU for those guests later on?
Regards,
