[PATCH v1 0/3] Provide a zero-copy method on KVM virtio-net.

2010-03-06 Thread xiaohui . xin
The idea is simple, just to pin the guest VM user space and then let host NIC driver has the chance to directly DMA to it. The patches are based on vhost-net backend driver. We add a device which provides proto_ops as sendmsg/recvmsg to vhost-net to send/recv directly to/from the NIC driver. KVM

[PATCH v1 1/3] A device for zero-copy based on KVM virtio-net.

2010-03-06 Thread xiaohui . xin
From: Xin Xiaohui xiaohui@intel.com Add a device to utilize the vhost-net backend driver for copy-less data transfer between guest FE and host NIC. It pins the guest user space to the host memory and provides proto_ops as sendmsg/recvmsg to vhost-net. Signed-off-by: Xin Xiaohui

[PATCH v1 2/3] Provides multiple submits and asynchronous notifications.

2010-03-06 Thread xiaohui . xin
From: Xin Xiaohui xiaohui@intel.com The vhost-net backend now only supports synchronous send/recv operations. The patch provides multiple submits and asynchronous notifications. This is needed for zero-copy case. Signed-off-by: Xin Xiaohui xiaohui@intel.com --- drivers/vhost/net.c |

[PATCH v1 3/3] Let host NIC driver to DMA to guest user space.

2010-03-06 Thread xiaohui . xin
From: Xin Xiaohui xiaohui@intel.com The patch let host NIC driver to receive user space skb, then the driver has chance to directly DMA to guest user space buffers thru single ethX interface. Signed-off-by: Xin Xiaohui xiaohui@intel.com Signed-off-by: Zhao Yu yzha...@gmail.com

Performance of virtio-blk?

2010-03-06 Thread Asdo
Dear kvm developers firstly thank you for doing such a great job on KVM. Following this list I see great ongoing progresses on virtio-net, now even more with the vhost but I see virtio-blk very rarely mentioned. We have an old kvm installation (host kernel is also old at 2.6.24) and I don't
