Hi all,
In IOMMU architecture , how to make two different peripherals share the same page table ?
In other words , is there a mechanism or structure to make two peripherals get completely different address.
eg:
peri-A、peri-B and peri-C share the same iova address 0-1G for some performance requests.
So the A,B,C need to use the same IOVA generator to ensure this,but I don't find an architecture to make this.
Any help will be appreciated.
