The Latest Sheaves Work To Hopefully Improve Linux Performance

([Linux Kernel] 24 October 01:49 PM EDT Sheaves Performance)

Merged for Linux 6.18 was a new feature called Sheaves as an opt-in, per-CPU array-based caching layer. Plus there is a per-NUMA-node cache of Sheaves called a "Barn". In continuing to build out the Linux kernel usage of Sheaves, a set of initial patches were posted this week to replace the CPU slabs with Sheaves within the slub allocator code.

New Code Allows VCE 1.0 Video Acceleration To Work On AMDGPU Driver For GCN 1.0 GPUs

([Radeon] 24 October 06:22 AM EDT Thanks Valve)

Valve contractor Timur Kristóf for their Linux graphics driver team has been working on improving Linux driver support for old AMD Radeon GCN 1.0 and GCN 1.1 generation GPUs. This has been about improving the AMDGPU driver to fill remaining gaps in GCN 1.0/1.1 support with those graphics cards by default relying on the older "Radeon" DRM kernel graphics driver compared to the AMDGPU driver used by default with GCN 1.2 and later. Another feature gap for AMDGPU is now being addressed with Video Coding Engine 1.0 support.

([Free Software] 24 October 06:10 AM EDT Patina 13.0)

Patina 13.0 is now available as this Rust implementation of UEFI firmware. Patina has been working to replace the core UEFI firmware components in a pure Rust implementation to avoid the use of C code.



Linux's Kconfig Is No Longer Orphaned

([Linux Kernel] 24 October 05:55 AM EDT Kconfig Maintainers)

Back in August, open-source developer Masahiro Yamada stepped down from maintaining the Kconfig and Kbuild areas of the Linux kernel. While Kbuild maintainership was quickly passed on, no one immediately stepped up to maintain Kconfig as the infrastructure code for configuring the Linux kernel builds. That led to Kconfig officially being orphaned code within the kernel but now that situation has been addressed.



Intel Begins Adding Nova Lake Xe3P To Linux OpenGL/Vulkan Drivers - Some Will Lack Ray-Tracing

Canonical's new push for their Snap app packaging/sandboxed format on Ubuntu Linux is for AI large language models (LLMs). Making it more interesting though is that they are working to deliver silicon-optimized AI LLMs for your hardware and to make it easily deployable for Ubuntu sers.



Linux's Proposed Cache Aware Scheduling Benchmarks Show Big Potential On AMD EPYC Turin

([Software] 23 October 01:00 PM EDT 18 Comments)

The past number of months has seen a lot of work by Intel Linux kernel engineers on cache-aware scheduling / load balancing for helping modern CPUs that have multiple caches. With cache aware scheduling, tasks that will likely share resources could be aggregated into the same cache domain to enjoy better cache locality. With the cache aware scheduling patches recently updated and now working past the "request for comments" stage, I was eager to try out these new patches. Especially with a 44% time reduction reported for one of the benchmarks, I was eager to run some tests and the first of those results are being shared today.
