Airlie Exploring Possibility Of VA-API On Top Of Vulkan Video

Well known open-source Linux graphics expert David Airlie of Red Hat has recently been working on early Vulkan Video support for Mesa's Radeon "RADV" and Intel "ANV" drivers. As part of that effort and in part due to lack of software making use of Vulkan Video extensions right now, he has started exploring the feasibility of implementing the Video Acceleration API (VA-API) atop Vulkan Video.

Another Sizable Performance Optimization To Benefit Network Code With Linux 5.17

Last week I wrote about a big TCP performance optimization having been queued up into net-next for Linux 5.17. That optimization can yield significant TCP throughput improvements especially with today's high-end 100Gb+ network hardware. There is now another separate juicy optimization to benefit the Linux network performance in the next kernel cycle.
