2014-06-19Add new vhost-user netdev backendNikolay Nikolaev1-0/+17
Add a new QEMU netdev backend that is intended to invoke vhost_net with the vhost-user backend. It uses an Unix socket chardev to establish a communication with the 'slave' (client and server mode supported). At runtime the netdev will handle OPEN/CLOSE events from the chardev. Upon disconnection it will set link_down accordingly and notify virtio-net; the virtio-net interface will go down.

2014-06-19virtio-net: announce self by guestJason Wang2-0/+22
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 Pulavarty1-0/+2
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_iommu: Get rid of window_size in sPAPRTCETableAlexey Kardashevskiy2-4/+1
This removes window_size as it is basically a copy of nb_table shifted by SPAPR_TCE_PAGE_SHIFT. As new dynamic DMA windows are going to support windows as big as the entire RAM and this number will be bigger that 32 capacity, we will have to do something about @window_size anyway and removal seems to be the right way to go. This removes dma_window_start/dma_window_size from sPAPRPHBState as they are no longer used. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>
