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

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.

GTK 4.22 To Natively Support SVG - Including Animations

GTK has long supported Scalable Vector Graphics (SVG) for icons but with up until recently relying on the external librsvg library, the integration hasn't been perfect. But Red Hat engineer Matthias Clasen has been working on having the GTK toolkit natively support SVG...

Linux Looks To Orphan Its ISDN Subsystem

Integrated Services Digital Network (ISDN) usage is long obsolete even where it had enjoyed some successes in the likes of Germany and Norway. With no activity in years to the ISDN and mISDN subsystem code for the Linux kernel, a patch was sent out today for orphaning the code...

Qualcomm Plumbing "SSR" Support To Deal With Crashes On AI Accelerators

Crashes on NPUs and AI accelerators are unfortunately a thing and yet another obstacle to worry about it with modern computing. Qualcomm developers have sent out patches for Sub-System Restart "SSR" functionality for their Qualcomm AI Accelerator (QAIC) driver for Linux to handle restarts when workload crashes occur on their AI accelerator hardware...

Oracle OCI Compute E6 Benchmarks For Leading AMD EPYC Turin Performance In The Cloud

Oracle recently launched their E6 compute shape for Oracle Cloud and powered by AMD EPYC 9005 "Turin" processors. Oracle Cloud Infrastructure also launched their Compute Cloud@Customer X11 and Private Cloud Appliance X11 platforms that are all powered by the E6 compute shape with 5th Gen AMD EPYC. For those curious about the performance and value of the Oracle Cloud E6 shape compared to prior-gen E5 as well as alternatives from Amazon AWS, Microsoft Azure, and Google Cloud, these benchmarks are geared for you.

LLVM Lands Some Long Overdue Tuning Optimizations For AMD Zen 4

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

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

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...
