If you're having to figure out what kind of a device you have then I think
you're already doing something else wrong. I'd expect the bits of code that
needs to identify device
Hi,
I'm working on implementing AMD IOMMU emulation in QEMU/KVM and I'm also
creating an API for address translation and access checking. Ideally,
this API should work with different kinds of devices and IOMMUs. These
operations would typically require specific device information to figure
out whi
