From my close monitoring of the many "-next" Git development branches along with some early pull requests already submitted, here is a look at some of the features that will likely be found in Linux 6.5 barring any last minute issues or objections from Linus Torvalds himself...

Earlier this month I ran some fresh benchmarks of Zink OpenGL-on-Vulkan against RadeonSI. While Zink in general is already quite speedy and in good shape for most workloads, those tests uncovered some troubled spots and Zink lead developer Mike Blumenkrantz of Valve has been diving into some of those issues with fixes. Another merge request is pending to deal with inefficiencies in the Mesa Vulkan windowing system integration (WSI) code...

Added to the Linux kernel back in 2020 was a community-written Corsair power supply driver for exposing various sensor data that their higher-end PSUs make available via a USB interface. This reverse-engineered "corsair-psu" driver has continued to be improved upon and adding support for newer Corsair PSUs. A new patch out this weekend extends the corsair-psu driver for handling newer 2022~2023 model power supplies...

With it having been another smooth week so far in the upstream kernel world, it's looking like Linus Torvalds is likely to promote Linux 6.4 tomorrow rather than going ahead with an extra release candidate. As such, here's a reminder about what makes Linux 6.4 a great summer-time kernel upgrade...

With the latest Mesa 23.2 code as of Friday there is now a rather significant performance optimization for Intel's graphics driver stack that really helps out Intel Arc Graphics DG2/Alchemist along with upcoming Meteor Lake graphics. Counter-Strike: Global Offensive, for example, was found to be 11% faster now with this single driver change and other Vulkan apps/games benefiting as well...
