Date: Mon, 25 Feb 2013 16:27:45 +0100 Message-ID: <1361806070-62465-1-git-send-email-cornelia.huck@de.ibm.com> Return-path: Sender: kvm-owner@vger.kernel.org List-Archive: List-Post: To: Marcelo Tosatti , Gleb Natapov Cc: Christian Borntraeger , Carsten Otte , Alexander Graf , Heiko Carstens , Martin Schwidefsky , "Michael S. Tsirkin" , KVM , linux-s390 , qemu-devel List-ID: Here's the latest version of my patch series enabling ioeventfds on s390, again against kvm-next. Patches 1 and 2 (cleaning up initialization and exporting the virtio-ccw api) would make sense even independent of the ioeventfd enhancements. Patches 3-5 are concerned with adding a new type of ioeventfds for virtio-ccw notifications on s390. The naming is now hopefully clearer. We won't add ioeventfd support for the legacy s390-virtio transport. Please consider applying. v2 -> v3: - Added a patch exporting the virtio-ccw api and use it for the diagnose implementation. - Better naming: We're dealing with virtio-ccw notifications only. v1 -> v2: - Move irqfd initialization from a module init function to kvm_init, eliminating the need for a second module for kvm/s390. - Use kvm_io_device for s390 css devices. Cornelia Huck (5): KVM: Initialize irqfd from kvm_init(). KVM: s390: Export virtio-ccw api. KVM: Introduce KVM_VIRTIO_CCW_NOTIFY_BUS. KVM: ioeventfd for virtio-ccw devices. KVM: s390: Wire up ioeventfd.
