Hi, the following patches are for Linux running as a guest under a host with virtio-ccw support. Patch 1 makes the kvm_virtio driver exit gracefully if the page containing s390-virtio information it expects is not present; it could probably go in seperately from the other patches. Patch 2 exports a needed interface. Patch 3 adds a driver handling virtio-ccw devices. The virtual subchannels have ccw devices with a special CU id this driver matches for. The virtio_ccw driver handles configuration and operation via the special new channel commands. Patch 4 is a split out of common code. Cornelia Huck (4): s390/kvm: Handle hosts not supporting s390-virtio. s390: Add a mechanism to get the subchannel id. s390/kvm: Add a channel I/O based virtio transport driver. s390/kvm: Split out early console code. arch/s390/include/asm/ccwdev.h | 5 + arch/s390/include/asm/irq.h | 1 + arch/s390/kernel/irq.c | 1 + drivers/s390/cio/device_ops.c | 10 + drivers/s390/kvm/Makefile | 2 +- drivers/s390/kvm/early_printk.c | 42 +++ drivers/s390/kvm/kvm_virtio.c | 46 ++- drivers/s390/kvm/virtio_ccw.c | 760 ++++++++++++++++++++++++++++++++++++++++ 8 files changed, 841 insertions(+), 26 deletions(-) create mode 100644 drivers/s390/kvm/early_printk.c create mode 100644 drivers/s390/kvm/virtio_ccw.c -- 1.7.11.4 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
