With the KVM code set to be merged in the coming weeks for the Linux 5.14 kernel, support for fast XMM hypercalls is coming for its Hyper-V guest support in allowing for some performance benefits...

It's been three months since AMD published a security whitepaper outlining the possibility of a side channel attack with PSF. The Predictive Store Forwarding functionality is new to AMD Zen 3 (Ryzen 5000 / EPYC 7003 series) processors and as part of their security analysis they are allowing users the ability to opt-out of using this feature in the name of greater security but the feature still hasn't been picked up for the mainline Linux kernel...

While Valve has been working on Vulkan-based rendering for Source Engine games by making use of DXVK for translating the game engine's native Direct3D calls to the Vulkan API, with some yet-to-be-merged Mesa patches around Gallium Nine there is much better performance to see with Gallium Nine at least for the RadeonSI driver...

The Qt Company has announced the debut of Qt 6.2 Alpha as it prepares for its September release with many more modules finally making the transition from Qt5 to Qt6...

Announced two years ago was the OpenPOWER Microwatt as an FPGA-based soft CPU core...

Last week Valve introduced Vulkan rendering support for Left 4 Dead 2. The L4D2 Vulkan support is similar to that of Portal 2 where DXVK is being leveraged for translating the Direct3D calls to Vulkan rather than relying on their OpenGL translations. For those wondering what this means for L4D2 performance on Linux with modern GPUs, here are some benchmarks of Left 4 Dead 2 when testing the OpenGL and Vulkan rendering options.

Landing in mainline Mesa 21.2 development code last week was the "Crocus" Gallium3D driver for old Intel hardware spanning from the Intel 965 chipset days "Gen4" up through Crocus supporting Haswell "Gen7" graphics. The i965 to Haswell span has been the focus since the official Intel "Iris" Gallium3D driver already in Mesa supports the Broadwell "Gen8" up through all current Intel UHD/Xe Graphics. But now Crocus with the latest Mesa code has added Gen8 support...

Intel-owned Habana Labs has submitted their set of driver updates to char/misc ahead of the upcoming Linux 5.14 merge window...

Even though Vulkan ray-tracing support on Intel graphics hardware isn't coming until Xe HPG avaiability, Intel's Linux graphics driver developers have been preparing since last year. In preparation for the Xe HPG launch, Intel's open-source talent have for many months already been preparing the Vulkan ray-tracing functionality wither another batch of code being merged today...

Intel CEO Pat Gelsinger continues working on restructuring the company and today announced some new leadership as well as business unit changes...

While in the past we have seen Intel CPU microcode updates lead to measurable performance differences on multiple occasions, this month's CPU microcode update doesn't end up being all that concerning for real-world performance...

Hitting mainline Mesa today for Mesa 21.2 next quarter is PanVK as the open-source Vulkan driver in development for newer Arm Mali GPUs...

NVIDIA announced yesterday they would be releasing DLSS Linux support tomorrow and indeed they have delivered on that first milestone of Deep Learning Super Sampling support for Linux gamers. NVIDIA has published their first 470 driver series beta in the form of the NVIDIA 470.42.01 build...

AMD today released FidelityFX Super Resolution that was announced earlier this month at Computex. Today it's Windows-only with no Linux support being introduced. FidelityFX Super Resolution is open-source but the code drop will not be until next month...
