The Latest Sheaves Work To Hopefully Improve Linux Performance
24 October 01:49 PM EDT - Linux Kernel - Sheaves Performance - 4 Comments

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.

AMD's ISP4 image signal processing IP is so far just used by the HP ZBook Ultra G1a laptop but will presumably be used by more of the higher-end AMD Ryzen next-gen laptops. AMD engineers today posted their fifth iteration of their open-source Linux driver for enabling the ISP4 use.

New Code Allows VCE 1.0 Video Acceleration To Work On AMDGPU Driver For GCN 1.0 GPUs
New Code Allows VCE 1.0 Video Acceleration To Work On AMDGPU Driver For GCN 1.0 GPUs
24 October 06:22 AM EDT - Radeon - Thanks Valve - 20 Comments

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.

Linux's Kconfig Is No Longer Orphaned
Linux's Kconfig Is No Longer Orphaned
24 October 05:55 AM EDT - Linux Kernel - Kconfig Maintainers - Add A Comment

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.

Linux's Proposed Cache Aware Scheduling Benchmarks Show Big Potential On AMD EPYC Turin
Linux's Proposed Cache Aware Scheduling Benchmarks Show Big Potential On AMD EPYC Turin
23 October 01:00 PM EDT - Software - 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.

Merged today to the LLVM/Clang compiler codebase are some long overdue adjustments to the AMD Zen 4 "znver4" CPU model for more accurately assessing various latency timings and micro-ops. These values were initially copied over from the Zen 3 (znver3) target but never adjusted properly for Zen 4 until now when an independent contributor took to sorting it out.

Linux 6.18 Adding AWCC Profile Support For The Dell G15 5530
22 October 09:11 AM EDT - Hardware - Alienware WMI Driver Support - Add A Comment

For those that happen to have the Dell G15 5530 laptop or considering this Intel Core i7 13650HX + NVIDIA GeForce RTX high-end laptop, the upcoming Linux 6.18 kernel is set to have AWCC platform profile support for this model as a nice enhancement. In turn this patch should also be back-ported to future stable Linux kernel point releases.

Intel Xe3P_LPD Display Support For Linux Being Built Out Ahead Of Nova Lake
22 October 06:27 AM EDT - Intel - Xe3P_LPD Display - Add A Comment

Earlier this month Intel Linux software engineers began posting patches for enabling Xe3P kernel graphics driver support with initial usage by Nova Lake processors and later the expected Celestial discrete GPUs. That initial Xe3P iGPU support is going into Linux 6.19 but expect more feature additions and optimizations in follow-on kernel cycles in 2026. Similarly the patches have now begun coming out for enabling the display engine capabilities for "Xe3P_LPD" for actually being able to drive displays (monitors) with Xe3P on Nova Lake.
