[dpdk-dev] ethdev: fix link status race condition

Hi, I looked in your patch ethdev: fix link status race condition (d5790b03), and have a question. According to your change when dev_start is called and the device supports lsc we doesn't ask the device status. But, if the device is already up, when you start dpdk application, the application c

[dpdk-dev] [PATCH v2 1/1] vhost: fix leak of fds and mmaps

The common vhost code only supported a single mmap per device. vhost-user worked around this by saving the address/length/fd of each mmap after the end of the rte_virtio_memory struct. This only works if the vhost-user code frees dev->mem, since the common code is unaware of the extra info. The VHO

[dpdk-dev] [PATCH v2 0/5] Optimize memcpy for AVX512 platforms

This patch set optimizes DPDK memcpy for AVX512 platforms, to make full utilization of hardware resources and deliver high performance. In current DPDK, memcpy holds a large proportion of execution time in libs like Vhost, especially for large packets, and this patch can bring considerable benefit
