[Qemu-devel] [PATCH v5 6/7] intel_iommu: reject broken EIM

2016-10-10 Thread Radim Krčmář
Cluster x2APIC cannot work without KVM's x2apic API when the maximal APIC ID is greater than 8 and only KVM's LAPIC can support x2APIC, so we forbid other APICs and also the old KVM case with less than 9, to simplify the code. There is no point in enabling EIM in forbidden APICs, so we keep it ena
