From: Erwan Yvin <erwan.yvin at stericsson.com> This driver depends on Rusty's new host virtio ring implementation, so this patch-set is based on the vringh branch in Rusty's git. with the vringh wrapper patch on top. They do not apply cleanly on top of the remoteproc virtio config patches from Sjur, but it merges fine. CAIF will use this new host virtio ring implementation. Ido,

Rusty, here is just patch 1 (using bool as return value in notify API). Thanks. Heinz Graalfs (9): virtio_ring: change host notification API virtio_ring: let virtqueue_{kick()/notify()} return a bool virtio_net: verify if virtqueue_kick() succeeded virtio_test: verify if virtqueue_kick() succeeded virtio_ring: add new function virtqueue_is_broken() virtio_blk: verify if queue is

Hi, this patch-set solves a hang situation when a vlan network device is hot-unplugged from a KVM guest. On System z there exists no handshake mechanism between host and guest when a device is hot-unplugged. The device is removed and no further I/O is possible. The guest is notified about the hard removal with a CRW machine check. As per architecture, the host must repond to any I/O operation

I've renewed this again, with some comments from HPA. I've tried to keep the new patches separate, so you can see the changes since we last discussed this (and so it's easy to back it out if we decide it's insane). I haven't even looked at the QEMU side so this is completely untested. Comments gratefully received! Rusty. Michael S Tsirkin (1): pci: add pci_iomap_range
