From f41389ae3c54bd5e2040e3f95a2872981c3ed965 Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Fri, 31 Oct 2014 13:38:18 +0000 Subject: KVM_CAP_IRQFD and KVM_CAP_IRQFD_RESAMPLE checks Compute kvm_irqfds_allowed by checking the KVM_CAP_IRQFD extension. Remove direct settings in architecture specific files. Add a new kvm_resamplefds_allowed variable, initialized by checking the KVM_CAP_IRQFD_RESAMPLE extension. Add a corresponding kvm_resamplefds_enabled() function. A special notice for s390 where KVM_CAP_IRQFD was not immediatly advirtised when irqfd capability was introduced in the kernel. KVM_CAP_IRQ_ROUTING was advertised instead. This was fixed in "KVM: s390: announce irqfd capability", ebc3226202d5956a5963185222982d435378b899 whereas irqfd support was brought in 84223598778ba08041f4297fda485df83414d57e, "KVM: s390: irq routing for adapter interrupts". Both commits first appear in 3.15 so there should not be any kernel version impacted by this QEMU modification.
