Libreboot as the downstream of Coreboot focused on providing fully open-source system firmware without binary blobs has been quite active recently. There have been several new systems added recently, introducing support for shipping ROMs without CPU microcode included, and other changes. This latest wor has culminated into the Libreboot 20230625 release...

With Linux 6.4 expected for release today the Linux 6.5 merge window will then open. 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...

Red Hat announced today that CentOS Stream will now be the sole repository for public RHEL-related source code releases...

Introduced with 4th Gen Xeon Scalable "Sapphire Rapids" processors are various new accelerators available on select SKUs or via the Intel On Demand offering. One of the initial challenges there though is the early accelerator software support limitations and many upstream open-source (or even just widespread) software not yet enabled to make use of these new accelerators. One of the improvements on that front has been Intel engineers working on an IAA crypto compression driver for the kernel so that the In-Memory Analytics Accelerator can be transparently accessible to kernel features making use of the crypto API...

Patches being queued ahead of the upcoming Linux 6.5 kernel merge window prepare initial support for DEXCR that is found in recent Power ISA specifications...

CPU microcode updates are commonly done in the name of security fixes and resolving functionality issues.. In recent years, CPU microcode updates have been a much more common -- and important -- occurrence. While all modern CPUs rely on microcode it's just a matter of whether the version used is baked into the hardware or an updated version loaded by the BIOS or OS at boot time, a "vocal minority" of users are unhappy with CPU microcode being included in Libreboot ROMs. Thus moving forward there will be alternative builds of Libreboot for different motherboards with the CPU microcode stripped out in the name of software freedom...

If your newer desktop motherboard has a NCT6799D Super I/O controller or one of the variants like NCT6799D-S, the Linux 6.5 kernel is set to introduce support for this ASIC in order to expose hardware sensor support under Linux...
