With AMD RDNA2 GPUs such as the Radeon RX 6000 series there is hardware support for AV1 decoding while the Linux support has been slow to materialize. Fortunately, that's now changing...
With LLVM/Clang 13 feature development having ended last week and the 13.0 release candidate being tagged, in starting off the benchmarking cycle first up I was looking at how well this new compiler is performing compared to LLVM Clang 12 stable on an AMD EPYC 7543 (Zen 3) Linux server.
One of the most exciting Linux kernel innovations in recent years has been eBPF for an in-kernel virtual machine allowing sandboxed programs running within the Linux kernel. The Linux Foundation along with Microsoft and other partners are now forming the eBPF Foundation...
As I have covered in many Phoronix articles over the past number of months, it's been a lengthy road bringing up the DG1 graphics support on Linux with the Intel open-source engineers having to re-architect their "i915" kernel graphics driver to support device local memory, getting the GuC support into good shape, scheduler changes, beginning to make use of TTM for memory management, user-space API changes, and a ton of other changes in expanding the driver's scope from just catering to integrated graphics. But now it looks like the DG1 Linux support is about to be officially advertised...
AMD has upstreamed the Van Gogh binary-only firmware files necessary for the RDNA2 graphics to be initialized by the open-source driver on this forthcoming APU.'..
Introduced to the Linux kernel earlier this year with Linux 5.12 was IDMAPPED mounts that allow for different mounts to expose the same file or directory with different ownership. IDMAPPED mounts was designed with use-cases ranging from containers to systemd-homed and more as outlined in the earlier article. Btrfs is now ready to begin supporting IDMAPPED mounts...

With yesterday's launch day Radeon RX 6600 XT Linux review the benchmarks were conducted using the popular Mesa RADV open-source driver used by many Linux gamers considering it's the driver Valve has been relentlessly optimizing and is the default on most (or all) Linux distributions. For those wondering how the performance of RADV is comparing to that of AMD's closed-source "PRO" Vulkan driver distributed as part of the "Radeon Software for Linux" package, here are some benchmarks exploring that difference.
DXVK has proven to be a huge success for improving the experience of running Windows Direct3D 9/10/11 games on Linux by translating those D3D calls to Vulkan. DXVK-Native meanwhile is the newer spin-off effort around providing a DXVK-based build native for Linux to help in game ports that still can then rely on their Direct3D renderer path...

While Libre-SoC began as "Libre RISC-V" envisioned as a low-power graphics/Vulkan accelerator, it has morphed into a hybrid CPU/GPU design built on OpenPOWER and in very early form seeing test fabrication on a TSMC 180nm process. The latest funding received is now working on adding cryptographic improvements to it and/or the upstream OpenPOWER ISA...
Intel has another big batch of open-source kernel graphics driver updates it sent out to DRM-Next for queuing ahead of the upcoming Linux 5.15 cycle. The DG2 graphics card is getting wired up while this pull request does also finally remove the Cannon Lake "Gen 10" graphics that never materialized in commercial products...

The Radeon RX 6600 XT was announced at the end of July as AMD's newest RDNA2 graphics card and is optimized for a performant 1080p gaming experience. For those wondering about its performance, this morning the embargo lifts to be able to talk about its performance. Here are the first Linux gaming benchmarks of the Radeon RX 6600 XT against a wide assortment of other AMD Radeon and NVIDIA GeForce graphics cards.

Last month after Microsoft began publishing their Windows Insider Preview builds of Windows 11, I ran some early Windows 11 benchmarks against Linux using an AMD Ryzen 9 5950X. Linux led in those benchmarks on the AMD Zen 3 desktop while for those wondering if that still holds true for Intel hardware, here are benchmarks of a Core i9 11900K "Rocket Lake" desktop with Windows 10 21H1, Windows 11 in its latest preview build as of testing, and then compared to Arch Linux / Clear Linux / Ubuntu.
Audio/video encoders and decoders are one of the areas where usage of the Rust programming language has increasing interest for speed and safety. One of the most promising Rust-written encoders at the moment is Rav1e for AV1 video encoding and it's now working towards its v0.5 release...
Merged one month ago was RadeonSI enabling by default its optimization to replace uniforms with literals inside shaders. This uniform inlining helped with SPECViewPerf and other workloads but it turns out in the process sharply drove up CPU usage when running some games...
