Question: How are the error events(AER/RAS) from the Physical device handle= d in PMD? =20 To the best of my understanding, these should get propagated to PMD via VFI= O(in case we are using vfio-pci) but I cannot see changes in the VFIO to handle such = events. Forgive me if I am sounding na=EFve and please correct my understanding. Thanks! Best Regards Salil
