Hi all, I''ve got overlapped and offset support in both nread and nwrite. The only thing left before I want to release this (as 0.4.0) is to get NO_BUFFERING to work. Unfortunately, I can''t get it to work. Park, I looked at that site you sent (and borrowed some code from it), but I don''t see anything special happening for NO_BUFFERING. I thought it required VirtualAlloc() but I''m not sure. If anyone has any ideas on tha...

This patch adds experimental VMDq support (AKA Netchannel2 vmq) to the ixgbe driver. This applies to the Netchannel2 tree, and should NOT be applied to the "normal" development tree. To enable VMDq functionality, load the driver with the command-line parameter VMDQ=<num queues>, as in: $ modprobe ixgbe VMDQ=8 You can then set up PV domains to use the device by modifying your VM

.... nopen, nwrite, nclose? If we''re going to overload, how do we do it? Rewrite the code using C++? That would be fine with me since we''re assuming VC++ anyway I think. Second, I''m not entirely sure how to handle overlapped IO. If a user passes File::OVERLAPPED | File::NO_BUFFERING, should we automagically pass an overlapped structure to the method? Or should we decree that all write operations are asynchronous? Or perhaps create a separate "write_async" method that calls WriteFileEx()? Please let me know your thoughts. Thanks. Dan

Hi Michael, Excuse me for disturbing you with this letter! I?m using linux 4.7.2 virtio driver + X86 64 + smart nic to validate PF and VF virtio performance. The VF?s performance is >1Mpps, but the PF?s performance is only 500Kpps even if using 8 virtio queues. So I reviewed virtio iommu patch in detail. I worry dma map/unmap cost many cycles. Do you have any suggestion? Thanks a
