2014-06-19Add the vhost-user netdev backend to the command lineNikolay Nikolaev1-0/+4
The supplied chardev id will be inspected for supported options. Only a socket backend, with a set path (i.e. a Unix socket) and optionally the server parameter set, will be allowed. Other options (nowait, telnet) will make the chardev unusable and the netdev will not be initialised. Additional checks for validity: - requires `-numa node,memdev=..` - requires `-device virtio-net-*` The `vhostforce` option is used to force vhost-net when we deal with non-MSIX guests.

2014-06-19Add vhost-user as a vhost backend.Nikolay Nikolaev3-1/+348
The initialization takes a chardev backed by a unix domain socket. It should implement qemu_fe_set_msgfds in order to be able to pass file descriptors to the remote process. Each ioctl request of vhost-kernel has a vhost-user message equivalent, which is sent over the control socket. The general approach is to copy the data from the supplied argument pointer to a designated field in the message. If a file descriptor is to be passed it will be placed in the fds array for inclusion in the sendmsg control header. VHOST_SET_MEM_TABLE ignores the supplied vhost_memory structure and scans the global ram_list for ram blocks with a valid fd field set. This would be set when the '-object memory-file' option with share=on property is used.

Decouple vhost from the Linux kernel by introducing vhost_ops. The intention is to provide different backends - a 'kernel' backend based on the ioctl interface, and an 'user' backend based on a UNIX domain socket and shared memory interface.

vhost_dev_init will replace devfd and devpath with a single opaque argument. This is initialised with a file descriptor. When TAP is used (through vhost_net), open /dev/vhost-net and pass the fd as an opaque parameter in VhostNetOptions. The same applies to vhost-scsi - open /dev/vhost-scsi and pass the fd.

2014-06-19virtio-net: announce self by guestJason Wang1-0/+42
It's hard to track all mac addresses and their configurations (e.g vlan or ipv6) in qemu. Without this information, it's impossible to build proper garp packet after migration. The only possible solution to this is let guest (who knows all configurations) to do this. So, this patch introduces a new readonly config status bit of virtio-net, VIRTIO_NET_S_ANNOUNCE which is used to notify guest to announce presence of its link through config update interrupt.When guest has done the announcement, it should ack the notification through VIRTIO_NET_CTRL_ANNOUNCE_ACK cmd. This feature is negotiated by a new feature bit VIRTIO_NET_F_ANNOUNCE (which has already been supported by Linux guest). During load, a counter of announcing rounds is set so that after the vm is running it can trigger rounds of config interrupts to notify the guest to build and send the correct garps.

2014-06-16spapr_pci: Advertise MSI quotaBadari Pulavarty2-1/+1
Hotplug of multiple disks fails due to MSI vector quota check. Number of MSI vectors default to 8 allowing only 4 devices. This happens on RHEL6.5 guest. RHEL7 and SLES11 guests fallback to INTX. One way to workaround the issue is to increase total MSIs, so that MSI quota check allows us to hotplug multiple disks. This sets the quota to the maximum number of interupts XICS has which is 1024 now (XICS_IRQS). This moves XICS_IRQS from spapr.c to xics.h for wider visibility.

2014-06-16spapr: Add kvm-type propertyEduardo Habkost1-0/+25
The kvm-type machine option was left out when MachineState was introduced, preventing the kvm-type option from being used. Add the missing property to the sPAPR machine class, so it can be used.
