While this week saw the ratification of the Vulkan Video 1.0 extensions in stable form after being out as provisional extensions since early 2021, one of the sad aspects of it is still lacking support for the popular royalty-free VP9 and AV1 codecs. Fortunately, at least, it's been re-affirmed for VP9/AV1 support in 2023...
Fedora is looking at disallowing X.Org/XWayland clients of difference CPU endianness from connecting to the X.Org Server. Such a combination of different endianness between the X.Org Server and clients is rather rare these days but is yet another "large attack surface" of the X.Org Server that needs addressing...
Ampere Computing's SMPro is a system control processor that is an Arm Cortex-M3 serving as a co-processor and handles interfacing with the BMC, error handling, system booting, power fail detection, and other tasks.

One of the security improvements made by AMD with their 4th Gen EPYC "Genoa" processors is upping their Secure Memory Encryption (SME) support from 128-bit to now 256-bit AES-XTS. AMD Secure Memory Encryption can be used for helping thwart attacks on the main system memory, but at what performance cost? In this article is an initial look at the AMD EPYC Genoa performance with AMD SME enabled/disabled.

The "char/misc" changes have been merged for the in-development Linux 6.2 as the random catch-all area of the kernel for drivers not fitting well in other subsystem areas. Notably with this update for Linux 6.2 is continued work on enabling the Intel-owned Habana Labs Gaudi2 AI accelerator...
With the great AMD 4th Gen EPYC Linux performance showing significant generational uplift and dominating against the current Xeon Scalable "Ice Lake" competition, it's a combination of the twelve channels of DDR5 system memory support, up to 96 cores per socket, introduction of AVX-512, and other Zen 4 micro-architectural improvements. As follow-up testing articles to all of the Genoa data delivered thus far, over the weeks ahead I have additional benchmark results to share looking more closely at these different areas of improvement for AMD 4th Gen EPYC. In today's article is a look at the EPYC 9654 2P performance with AVX-512 on/off while also looking at the CPU power consumption impact and the affect on CPU clock frequencies and thermals.
In early 2021 the Vulkan Video extensions were published in beta/provisional form as a new industry-standard video encode/decode API with the context of Vulkan. As a nice Christmas gift this week from The Khronos Group, the extensions have been finalized as Vulkan Video 1.0 and are now deemed ready for production use...

Introduced at the start of the year was an experimental open-source project implementing the VA-API interface over NVIDIA's NVDEC video decoding API. In turn this VA-API support for running atop NVIDIA's proprietary Linux graphics driver allows for GPU video acceleration within Firefox and other software only targeting the Video Acceleration API. Now in closing out the year is a new NVIDIA-VAAPI-Driver release...
Merged back in Linux 5.13 last year was Landlock for allowing unprivileged application sandboxing.
