[Qemu-devel] [PATCH v2 00/16] Vhost-pci for inter-VM communication |
Date: |
Fri, 12 May 2017 16:35:32 +0800 |
This patch series implements vhost-pci, which is a point-to-point based
inter-vm communication solution. The QEMU side implementation includes the
vhost-user extension, vhost-pci device emulation and management, and inter-VM
notification.
v1->v2 changes:
1) inter-VM notification support;
2) vhost-pci-net ctrlq message format change;
3) patch re-org and code cleanup.
Wei Wang (16):
vhost-user: share the vhost-user protocol related structures
vl: add the vhost-pci-slave command line option
vhost-pci-slave: create a vhost-user slave to support vhost-pci
vhost-pci-net: add vhost-pci-net
vhost-pci-net-pci: add vhost-pci-net-pci
virtio: add inter-vm notification support
vhost-user: send device id to the slave
vhost-user: send guest physical address of virtqueues to the slave
vhost-user: send VHOST_USER_SET_VHOST_PCI_START/STOP
vhost-pci-net: send the negotiated feature bits to the master
vhost-user: add asynchronous read for the vhost-user master
vhost-user: handling VHOST_USER_SET_FEATURES
vhost-pci-slave: add "reset_virtio"
vhost-pci-slave: add support to delete a vhost-pci device
vhost-pci-net: tell the driver that it is ready to send packets
vl: enable vhost-pci-slave
