Hi Rob & Mihai, I wrote vhost-nvme patches on top of Christoph's NVMe target. vhost-nvme still uses mmio. So the guest OS can run unmodified NVMe driver. But the tests I have done didn't show competitive performance compared to virtio-blk/virtio-scsi. The bottleneck is in mmio. Your nvme vendor extension patches reduces greatly the number of MMIO writes. So I'd like to push it

In addition I think we'll eventually need an ops structure here,

Hi Hypothetical but quite possible scenerio: Attempted emergency 911 call but all zap channels are already in use. Is there any way to hangup zap channels before dial(Zap/g1/911) or equivalent. AFAIK hangup doesn't except options so I CANNOT do something like hangup(Zap/g1) to clear zap channels before the dial statement - this is what i was hoping to do. So what do other people do?

Data center backends use more and more RDMA or RoCE devices and more and more software runs in virtualized environment. There is a need for a standard to enable RDMA/RoCE on Virtual Machines. Virtio is the optimal solution since is the de-facto para-virtualizaton technology and also because the Virtio specification allows Hardware Vendors to support Virtio protocol natively in order to achieve

Hi, I've been following the instructions on how to use the LLVM Gold plugin at http://llvm.org/docs/GoldPlugin.html while building an multiple versions of WebKit. The documentation hasn't been updated since 2010 and hasn't really matched my experiences, so I'd like to ask if I'm doing these steps incorrectly. What I'm trying to do is force all compilation steps to

Hello all, I'm relatively new to "R" and programming in general - I had previously used MatLab, but decided to make the transition to R, as the computational times are much better! Anyway, I'm trying to use R to run a gamma distribution model to estimate mean transit times of water moving through a hydrological catchment. My input are 3 .txt format files as follow:

From: Mihai Rusu <dizzy at google.com> This implements the device side for an NVMe vendor extension that reduces the number of MMIO writes which can result in a very large performance benefit in virtualized environments. See the following link for a description of the mechanism and the kernel NVMe driver changes to support this vendor extension:
