The NTFS3 driver maintained by Paragon Software for Microsoft NTFS file-systems today saw a batch of improvements merged for Linux 7.0 This comes as there is also the competing "NTFS Remake" driver that began a few months ago as the "NTFSPLUS" driver. That NTFS Remake driver isn't looking like it will be submitted for the Linux 7.0 merge window so at least for now the NTFS3 driver continues seeing improvements with the latest mainline kernel code...

One of the limitations of the AMDGPU Linux kernel graphics driver has been the lack of its support for HDMI 2.1 and later. AMD has wanted to support HDMI 2.1+ functionality under Linux but it's been legally blocked by the HDMI Forum. But anxious independent users have been working on open-source patches for wiring up HDMI 2.1 into the AMDGPU driver outside of the realm of AMD and the HDMI Forum's blessings...

With memory pricing being as wild as it is these days and with MRDIMMs on Xeon 6 Granite Rapids offering much more memory bandwidth than conventional DDR5 RDIMMs, you may be wondering about the performance impact when not populating all twelve memory channels on the Xeon 6900 series processors. In this article are benchmarks to demonstrate the performance difference of MRDIMM-8800 memory across using six, eight, ten, and twelve MRDIMMs with a Xeon 6980P server.

This month I have been doing a lot of Panther Lake benchmarking under Linux with the Core Ultra X7 358H. One of the areas of much interest has been the Arc B390 Xe3 graphics that have been working nicely out-of-the-box with the Intel open-source driver stack on Linux although there still are some gaps to fill against Windows. Those Intel Arc B390 Linux benchmarks so far have been focused on OpenGL and Vulkan graphics, but what about OpenCL and GPU compute with the open-source Intel Compute Runtime? Today's article is looking at the performance of the Xe3 Panther Lake graphics on the newest Compute Runtime release compared to prior Intel graphics generations and the AMD Ryzen AI competition.

DRM Panic is the Linux kernel infrastructure now supported by most of the Direct Rendering Manager (DRM) kernel graphics/display drivers for being able to render a QR code kernel error message or similar when a kernel panic occurs to provide a cleaner interface should your system run into serious problems.

AMD Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP) provides memory encryption and integrity protections that can be especially useful in modern cloud computing. Typically a 2~10% performance overhead is reported when engaging AMD SEV-SNP for these hardware-backed security protections. In this article is an extensive look at the current AMD SEV-SNP performance impact for confidential computing on EPYC 9005 "Turin" servers. The current Ubuntu 24.04 LTS was tested as well as an Ubuntu 26.04 development snapshot in evaluating the latest optimizations and what is on the horizon this year for AMD EPYC Linux server performance.

As some long overdue housekeeping, the Linux 7.0 kernel has removed an Error Detection And Correction "EDAC" driver for the Intel 440BX and 440GX chipset. The driver is being removed not only because that chipset was just used by old Celerons and Pentium II / Pentium III CPUs but that it's been in the kernel all this time while being known to be broken for 19+ years...
