From d0bc7091c2013ad2fa164100cf7b17962370e8ab Mon Sep 17 00:00:00 2001 From: Matthew Rosato Date: Fri, 2 Sep 2022 13:27:34 -0400 Subject: s390x/pci: enable adapter event notification for interpreted devices Use the associated kvm ioctl operation to enable adapter event notification and forwarding for devices when requested. This feature will be set up with or without firmware assist based upon the 'forwarding_assist' setting.
