Last Thursday AMD finally sent out the basic enablement patch for AMD Zen 4 "znver4" with the GCC compiler. Once again it was tardy with Ryzen 7000 series processors already shipping and sadly the cost tables (tuning) is still catering to Zen 3 rather than updated for Zen 4. While as of today this -march=znver4 support has been merged into GCC 13...

Red Hat's storage team responsible for the Stratis solution has released a new feature update...

Windows users are increasingly making use of Mesa with Microsoft investing in supporting a number of different open, industry standard APIs and then layering them atop the underlying Direct3D 12 driver for the likes of WSL2 usage. OpenGL, OpenCL, Vulkan, and VA-API video acceleration have been the primary targets for Microsoft engineers working on Mesa with the Windows Subsystem for Linux in mind while also posing other possible use-cases where the host may lack native drivers for those APIs. For bettering Mesa on Windows, Microsoft has now added support for compiling against the DirectX 12 Agility SDK...

Earlier this year Coreboot and the Dasharo downstream were ported to the MSI PRO Z690-A DDR4 motherboard. This was very exciting in that a current-generation Intel desktop motherboard could run Coreboot and readily available through various Internet retailers. But many inquired about whether the MSI PRO Z690-A DDR5 variant would see similar support and now that too is being worked on...

While the Linux 6.1 merge window just passed and the "Call Depth Tracking" patches have been in development the past few months, it looks like that for the Linux 6.2 kernel is where that alternative mitigation technique will be introduced for helping offset some of the significant performance regressions incurred for Intel Skylake era processors as a result of recent CPU security vulnerability mitigations...

Two weeks ago was the release of systemd 252-rc1 with introducing the new systemd-measure command, a "support-ended" taint flag for OS images detected past their end-of-support date, and a wide variety of other changes and feature additions. Systemd 252-rc2 is now available for additional testing with various fixes plus a few more additions...

If you habitually ride Mesa Git for the latest and greatest open-source AMD Radeon graphics driver code and use the KDE Plasma desktop with Wayland, you may have noticed a glitchy cursor recently. Fortunately, that's now fixed up with today's Mesa Git code and ended up stemming from the recent global enabling of Mesa OpenGL threading...

Last week saw Intel sending out new GCC compiler patches for adding the "Sierra Forest" CPU target and the number of new x86_64 instructions it's adding. Those GCC patches follow Intel publishing an updated programming reference manual where they detailed these new instructions coming for Sierra Forest Xeon CPUs as well as Grand Ridge. Now on the LLVM compiler side, they too have begun landing new patches for these new Intel instructions...

Intel Arc Graphics A750 and A770 work on Linux if you are running the very latest Linux kernel and Mesa. The gaming experience is decent aside from occasional driver issues. One of the games that has been pesky with the open-source Intel "ANV" Vulkan driver has been the HITMAN 3 title running under Steam Play but with the newest Mesa 22.3 code should now be fixed up...

Coreboot 4.18 had been planned for release in August but after that slipped, this newest Coreboot feature release is now shipping and comes with many hardware support improvements and other changes for this open-source system firmware implementation...

Back in August I wrote about a patch to change AMD's CPU microcode loading on Linux to now patch every logical CPU thread rather than just per physical core. It turned out that at least some CPU microcode updates do make per-thread modifications while the Linux kernel microcode handling for AMD was just applying microcode updates at run-time on a per-core basis. That patch was seemingly forgotten about but has now been queued up as part of x86 "urgent" changes for the mainline kernel...

Microsoft has released its monthly update to CBL-Mariner 2.0, its in-house Linux distribution serving a variety of purposes from WSL to Azure...

Two weeks ago a bunch of old Mesa code got removed including the XvMC front-end, Rbug as a remote debugging interface, and some of Graw that was to serve as a raw Gallium3D interface without a traditional Gallium front-end. Some of Graw was accidentally left in the source tree while now that has been caught and eliminated in further lightening the size of Mesa...
