Yesterday Google Cloud launched their C2D instance type as their newest compute-optimized instances powered by AMD EPYC 7003 series processors. here are some quick benchmarks looking at the C2D performance against the existing Intel Xeon powered C2 instance type and the former EPYC 7002 based N2D instance type.

Intel engineers have been working heavily on the Linux's Compute Express Link (CXL) subsystem for kernel. As the next step in that endeavor, pending now is the CXL memory driver that looks like it will make its introduction in Linux 5.18...

A security researcher presented at last weekend's Free and Open source Software Developers' European Meeting (FOSDEM) conference around mitigating processor vulnerabilities like Spectre and Meltdown but without negligible performance cost...

While Advanced Vector Extensions (AVX) can provide some big performance boosts when software is properly tuned for it and most often we are writing about projects adding support for it, in the case of LibreOffice they are now going ahead and removing their AVX and AVX-512 tuning...

The newest code Microsoft has contributed to Mesa for its D3D12 driver, which is used for running OpenGL / OpenGL ES / OpenCL (and eventually Vulkan) over Direct3D 12 for use on Windows and WSL2, is Direct3D residency management support...

For those that enjoy the daily open-source/Linux news each and every day of the year along with all of our original Linux benchmarking / hardware review content, you can show your support this Valentine's Day with a special offer...

Btrfs file-system developers remain very busy on multiple fronts from performance and reliability enhancements to in-development Btrfs on-disk format changes. A notable item now on deck for integration in Linux 5.18 is Btrfs support for encoded I/O...

Back in November when Intel's 12th Gen Core "Alder Lake" processors first launched I ran benchmarks across operating systems and found Windows 11 delivering better performance than Linux with the Core i9 12900K flagship processor. Fortunately, thanks to kernel improvements since Linux 5.16, that is largely no longer the case. Here is a fresh look at the i9-12900K performance under Ubuntu 22.04 daily with Linux 5.16 and 5.17-rc3 kernels tested as well and Clear Linux for Intel's very own reference Linux platform.

AMD just announced that it has received approval from all necessary regulators to proceed with its acquisition of Xilinx...

Linux 5.18 is looking to be another very busy kernel cycle for Intel as in addition to Alder Lake N graphics, the Intel Hardware Feedback Interface (HFI), and integrating Software Defined Silicon (SDSi), Intel's PECI kernel code is finally being mainlined...

Overnight AMD quietly released ROCm 5.0 for improving the Radeon Open eCosystem. Most exciting with ROCm 5.0 is having some level of Navi 2x / RDNA2 GPU support!..

Hitting the LLVM 15.0 development tree this morning are the initial patches for China's LoongArch CPU architecture...

The Radeon Software for Linux packaged enterprise driver is preparing for its Q1'2022 update...

DirectFB2 is in development with work on it having started last year after the original DirectFB project ceased development a half-decade ago. While more embedded/mobile platforms have moved on from DirectFB and now targeting Wayland, DirectFB2 hopes to restore its viability for embedded systems...

One of the recurring FOSDEM talks we have come to enjoy has been Oracle's Daniel Kiper providing an annual update on the GRUB bootloader development efforts. This past weekend at FOSDEM 2022 was the latest on this leading open-source bootloader with recent accomplishments and plans for this year...

We still don't know what features Intel is planning to capitalize upon with their Software Defined Silicon "SDSi" functionality in future CPUs, but it turns out the kernel mainlining of the necessary software support is now expanded to land with Linux 5.18. With the SDSi kernel support coming together rather quickly, it's possible we could be seeing Software Defined Silicon rather soon...

Along with yesterday marking the release of KDE Plasma 5.24, KWinFT 5.24 debuted as the newest version of this KWin compositor fork that continues focusing on providing Wayland support, new features, and modernizing the codebase...

GNU Binutils 2.38 is out today as the newest feature release to this collection of free software utilities very common to Linux systems and other platforms...

Intel on Tuesday submitted to DRM-Next what is likely to be their biggest set of feature updates for their "i915" kernel graphics driver in this spring's Linux 5.18...

The LUMI supercomputer in Finland is still being assembled with its 2,560 nodes consisting of a 64-core AMD Trento CPU and four AMD Instinct MI250X GPU accelerators per node. This 375+ PFLOPs was supposed to come online by the end of 2021 but was challenged by the supply chain crisis and is now aiming for general availability by the middle of the year. While the hardware is still coming together, their HPC engineers have been hard at work optimizing the open-source Linux software stack...
