[RFC] Virtual Machine Device Queues(VMDq) support on KVM
...backend service. 2) Virtio-net backend service encapsulates multiple vqueue elements into multiple AIO control blocks and composes them into one AIO read request. 3) Virtio-net backend service uses io_submit() syscall to pass the request to the TUN/TAP device. 4) Virtio-net backend service uses io_getevents() syscall to check the completion of the request. 5) The TUN/TAP driver receives packets from the queue pair of NIC, and prepares for Direct I/O. A modified NIC driver may render a skb which header is allocated in host kernel, but the payload buffer is directly mapped from user space buffer...

[PATCH 0/9] tools: remove or disable old/useless/unused/unmainted stuff
depends on "autoconf: regenerate configure scripts with 4.4 version" This series removes some of the really old deadwood from the tools build and makes some other things which are on their way out configurable at build time with a default depending on how far down the slope I judge them to be. * nuke in tree copy of libaio * nuke obsolete tools: xsview, miniterm, lomount & sv *

[RFC PATCH 2/2] block: virtio-blk: support multi virt queues per virtio-blk device
...s to support that first, then provide test data with > more queues(8, 16). Hi Ming Lei, would you like to repost these patches now that MQ support is in the kernel? Also, I changed my mind about moving linux-aio to AioContext. I now think it's a good idea, because it limits the number of io_getevents syscalls. O:-) So I would be happy to review your patches for that as well. Paolo

[PATCH 0 of 4] aio event fd support to blktap2
Get blktap2 running on pvops. This mainly adds eventfd support to the userland code. Based on some prior cleanup to tapdisk-queue and the server object. We had most of that in XenServer for a while, so I kept it stacked. 1. Clean up IPC and AIO init in tapdisk-server. [I think tapdisk-ipc in blktap2 is basically obsolete. Pending a later patch to remove it?] 2. Split tapdisk-queue into

[PATCH] Blktap: Userspace file-based image support. (RFC)
Attached to this email is a patch containing the (new and improved) blktap Linux driver and associated userspace tools for Xen. In addition to being more flavourful, containing half the fat, and removing stains twice as well as the old driver, this stuff adds a userspace block backend and let you use raw (without loopback), qcow, and vmdk-based image files for your domUs. There''s also a
