An open letter started by the Open-Source Firmware Foundation and seeking community support for this letter is calling on Intel to open-source their Firmware Support Package (FSP). The FSP binary blob has been a big limitation to the level of openness around firmware for Intel systems and has been a limiting factor in supporting the likes of Coreboot, LinuxBoot, and other technologies on Intel hardware...

A new patch series posted today by AMD is enabling peer-to-peer support within their AMDKFD kernel compute driver for allowing communication between multiple AMD GPUs over the PCIe bus without needing intermediate copies through system memory.

While Ubuntu 22.04 LTS was just released over one month ago, it is shipping on the Linux 5.15 kernel that was already two stable series behind at release time but chosen as the default due to its long-term support status. Ubuntu 22.04 also shipped with Mesa 22.0 as the latest stable version albeit the open-source OpenGL/Vulkan graphics drivers are quick to advance. So if you've been thinking about upgrading Mesa or the Linux kernel on your Ubuntu 22.04 system for better Linux gaming performance, here are some benchmarks looking at such performance impact for AMD RDNA2 / Radeon RX 6000 series graphics.
