Google as part of their involvement in the Open-Source Security Foundation (OpenSSF) has devised the "Criticality Score" as a means of judging crucial open-source projects...

For those wondering how the open-source Radeon Linux graphics drivers compare to the Radeon Software Windows drivers for the recently released Radeon RX 6800 XT, here are some preliminary data points looking at the OpenGL / Vulkan performance between Windows and Linux for RDNA 2.

One of the big features to look forward to with Intel's Xeon "Sapphire Rapids" is the introduction of AMX as the Advanced Matrix Extensions. While Sapphire Rapids looks to be at least one year out still, the company's open-source compiler engineers have already been hard at work on the software infrastructure support...

The Linux 5.11 merge window is expected to open next week and while AMD has already queued several rounds of updates into DRM-Next ahead of that period, some last minute items were submitted overnight for this next Linux kernel version and what will be the first major kernel release of 2021...

Following the original, first-generation PowerPC CPU support being removed in the Linux 5.10 kernel, the original PowerPC 400 series is also looking like it will now be removed as well from the kernel...

Raspberry Pi's V3DV Vulkan driver is on quite a streak lately. In addition to inclusion in Mesa 20.3, Vulkan 1.0 conformance, and Wayland support, more performance work is being pursued with those initial milestones reached...

While Apple continues to drive their own Metal graphics/compute API, Vulkan support built atop Metal continues to mature thanks to the open-source MoltenVK project. With the MoltenVK's latest update is now support for Apple Silicon with the M1's new GPU...

Back in May was AMD's celebration of the GPUOpen re-launch and that included the introduction of the Radeon Memory Visualizer (RMV) as their newest tool at the time. But rather strange for being a "GPUOpen" development tool is that it was Windows-only and not actually open-source. Today that has now changed with Radeon Memory Visualizer going open-source...

The highly anticipated Cyberpunk 2077 game will run on Linux on launch day by means of Steam Play!..

While AMD Smart Access Memory has already been supported under Linux for some time with its resizable BAR functionality, only now with all the excitement around the feature being promoted with the Ryzen 5000 series and Radeon RX 6000 series hardware is the Mesa driver code beginning to see some optimizations for it...

Last week AMD published their Zen 3 support for GCC code compiler. That initial support, which has already been merged into GCC 11, is the initial support flipping on newly supported instructions but not yet offering any tuned scheduler model or other optimizations compared to the existing Zen 2 path. In any case, here is a look at the performance changes with building the open-source benchmarks under test with "znver3" compared to the prior Zen 2 and Zen 1 targets along with generic x86_64 and then also looking at the performance if catering the compiler targets for Intel's Skylake and Haswell processors.

It's been just over one month since AMD launched the Ryzen 5000 series as the first processors part of the Zen 3 family. The Linux performance continues to be terrific with the Ryzen 5600X / 5800X / 5900X / 5950X parts in our continued benchmarking...

AMD has carried out a timely release of their RDNA 2 ISA documentation for those interested in working on any compiler support around these very latest graphics processors or working on other shader optimization approaches, etc...

A new SDL2 library release is being prepared for this widely-used, cross-platform abstraction layer popular with games for supporting a wide range of input devices / peripherals and other vast subsystem coverage in a portable manner...

There have been many workarounds and changes to the SDMA (System DMA) copy support within the RadeonSI Gallium3D driver since the support was introduced years ago, but it's now been outright removed due to too many generations of AMD Radeon hardware having issues with it enabled...

QEMU 5.2 was released on Tuesday as the latest feature release for this open-source processor emulator that plays an important role in the open-source Linux virtualization stack...

Intel's Deep Neural Network Library currently known as oneDNN as part of the oneAPI suite (and formerly known as MKL-DNN and DNNL) has reached version 2.0 as an open-source project...

The open-source Intel Graphics Compiler (IGC) that is currently used by their oneAPI Level Zero and OpenCL implementations but likely to see Intel driver Mesa usage in 2021 has a new feature dubbed "IMF LA" that aims to help with the performance and close the gap with Windows...

Four years after Google began developing the "Fuchsia" operating system complete with its own kernel, Google is now becoming more open with Fuchsia development and also accepting community code contributions...

Back in October RISC-V minded startup SiFive announced the HiFive Unmatched development board as the best RISC-V development board we've seen to date. But only having 8GB of RAM was one of the few critiques which the company is now addressing...
