KDE developer Xaver Hugl has written a blog post how the KWin compositor's DRM back-end has been working to move itself off GBM surfaces (gbm_surfaces) to instead allocate buffers directly and import them into EGL. This ultimately should be a win for the KWin compositor once everything is complete...

The Ubuntu 23.04 "Lunar Lobster" development builds recently transitioned from Linux 5.19 as in use by Ubuntu 22.10/22.04.2 to a Linux 6.1 based kernel. This led some -- including myself -- to wonder if Canonical changed course and shifted to Linux 6.1 LTS instead of the Linux 6.2 kernel that has been out as stable since last month. Fortunately, that's not the case and Ubuntu 23.04 is preparing to soon land Linux 6.2 across all kernel flavors...

From early December to late February there was an absence of new Compute-Runtime updates for that open-source stack for providing OpenCL and oneAPI Level Zero support for Intel graphics hardware on Linux. It was out of trend as they worked to move from a weekly~biweekly release rhythm to a monthly release cadence while taking extra time for making various other changes too. After that three month lull, they are back to pushing out new compute updates and damn it's looking nice. At least in my testing, the progress they've quietly made over the past few months has been very nice for the compute stack compatibility/support and performance.

The ipmitool utility on Linux systems is widely-used for controlling IPMI-enabled servers and other systems.

Linux 6.4 is set to remove the old CONFIG_SYSFS_DEPRECATED and CONFIG_SYSFS_DEPRECATED_V2 options that are used for running newer versions of the Linux kernel with very old Linux distributions and user-space tools. Pre 2007~2008 distributions as a result would likely run into trouble trying to run on Linux 6.4+ kernels...

While the AMD Ryzen 9 7900X3D and Ryzen 9 7950X3D are promoted as great "gaming processors", these new Zen 4 desktop CPUs with 3D V-Cache also have great capabilities for various technical computing workloads thanks to the hefty cache size. In prior articles I've looked at the Ryzen 9 7900X3D/7950X3D in around 400 workloads on Linux while in this article I am looking more closely at these technical computing areas where these AMD Zen 4 3D V-Cache processors show the most strength and value outside of gaming.

Back in 2021 Ruby merged the YJIT just-in-time compiler that last year with Ruby 3.2 was deemed production grade. There's also been the MJIT compiler that relies upon an external C compiler. And now landing this week in Ruby is RJIT as the newest just-in-time effort...

Since late 2020 there had been work by AMD Linux engineers on adding Smart Access Memory (Resizable BAR) support to RadeonSI as the Gallium3D OpenGL driver and improved since that point in the name of performance. However, for this OpenGL driver now they've come to realize the benefits haven't necessarily panned out and the developers went ahead and disabled this SAM/ReBAR support followed by removing the support from this driver...

Back in December initial AMD Zen 4 "znver4" support was merged for the LLVM/Clang 16 compiler. While the "-march=znver4" targeting at least flips on the newly-added AVX-512 instructions with these AMD processors, it was re-using the existing scheduler model from Zen 3. Finally today a tuned Zen 4 scheduler model has landed for what will be found in the LLVM 17 compiler later this year...
