With this weekend having seen more Zink refactoring code land and Zink being faster than RadeonSI at least for some operations, it was time to fire up some fresh benchmarks of this generic OpenGL-on-Vulkan implementation. From the newest Mesa code this weekend after the latest Zink patches were merged, here is a look at how the Zink performance is compared to the RadeonSI Gallium3D driver's native OpenGL support. All of the testing was done using an AMD Radeon RX 6800 XT graphics card.

For the past decade going back to the early GTK3 days there has been the "Broadway" back-end that allows for GTK interfaces to be rendered within HTML5 web browsers. Aside from demos and other toys, there hasn't been too much widespread use reported with this GTK HTML5 back-end and some distributions like Ubuntu and Debian haven't been shipping the Broadway support with the newer GTK4. However, that is changing now for Debian and with this autumn's release of Ubuntu 22.10...

Made public back in June by Intel was the MMIO Stale Data vulnerabilities. The disclosure noted affected Intel products range from Haswell up through Rocket Lake on the client side or Xeon Scalable Ice Lake servers. However, pre-Haswell Intel CPUs might be impacted too while the Linux kernel to this point was incorrectly stating older CPUs are "not affected" by MMIO Stale Data...

With Intel Xeon Sapphire Rapids expected to make more of a splash coming up, it's a good time to revisit the Intel Xeon Platinum 8380 "Ice Lake" performance to see how the Linux software performance has evolved since last year's launch.

VEIKK is a company I previously hadn't heard of that offers a range of pen displays and drawing tablets for digital artists. At first when they reached out around reviewing one of their drawing tablets, I questioned their Linux support but it turns out their graphics tablets do work across all major platforms. I've been trying out the VEIKK VK1200 the past few weeks and it's been working out decent as a 11.6-inch drawing monitor for just $169 USD.

VFX Reference Platform as a standards body that aims to help standardize software platforms in the realm of digital content creation (DCC) has published a detailed report for studios to consider in choosing their next Linux platform. Their new recommendations for visual effects and animation studios about moving to newer Linux distributions over the next year -- especially with many still relying on CentOS 7 -- is for moving to Red Hat Enterprise Linux 9 otherwise one of the downstreams like Rocky Linux or AlmaLinux. Close behind in their recommendations and as a longer-term objective is also tossing some support behind Ubuntu Linux...

Up to this point loading updated CPU microcode on AMD processors under Linux has checked just to ensure every physical CPU core was loaded with the new microcode but not sibling threads for SMT processors. While logically that makes sense, it turns out some AMD microcode updates do carry out per-thread modifications that means the microcode updating needs to be carried out on every thread. A Linux fix is on its way to the kernel to adjust that behavior...

As part of today's "drm-misc-fixes" pull request, NVIDIA Ampere GA103 GPU support is set to be added to the Nouveau DRM driver with Linux 6.0...

After Qualcomm announced their Cloud AI 100 Accelerator back in 2019, in 2020 during the early days of the pandemic they posted a Linux driver for this accelerator. That driver didn't get picked up for the mainline Linux kernel and two years later there still is little fanfare around the Qualcomm AI Cloud Accelerator hardware. However, now they have posted a new Linux driver that goes the DRM driver route...
