Hello Bjorn, On s390 we currently handle SRIOV within firmware. Which means that the PF is under firmware control and not visible to operating systems. SRIOV enablement happens within firmware and VFs are passed through to logical partitions. I'm working on a new mode were the PF is under operating system control (including SRIOV enablement). However we still need firmware support to access the VFs. The way this is supposed to work is that when firmware traps the SRIOV enablement it will present machine checks to the logical partition that triggered the SRIOV enablement and provide the VFs via hotplug events. The problem I'm faced with is that the VF detection code in sriov_enable leads to unusable functions in s390. Would you consider the following patches?
