Modern computing systems rely heavily on operating-system schedulers to allocate CPU time fairly and efficiently. Yet many of these schedulers operate blindly with respect to the meaning of workloads: they cannot distinguish, for example, whether a task is latency-sensitive or batch-oriented. This mismatch, between application semantics and scheduler heuristics, is often referred to as the semantic gap. A recent research framework called SchedCP aims to close that gap.

New Code Allows VCE 1.0 Video Acceleration To Work On AMDGPU Driver For GCN 1.0 GPUs
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…
Patina 13.0 Released As Rust UEFI Firmware Implementation
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
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…
Summary of the Amazon DynamoDB Service Disruption in Northern Virginia (US-EAST-1) Region
We apologize for the impact this event caused our customers. While we have a strong track record of operating our services with the highest levels of availability, we know how critical our services are to our customers, their applications and end users, and their businesses. We know this event impacted many customers in significant ways. We will do everything we can to learn from this event and use it to improve our availability even further.
VMScape: Cracking VM-Host Isolation in the Speculative Execution Age & How Linux Patches Respond
In the world of modern CPUs, speculative execution, where a processor guesses ahead on branches and executes instructions before the actual code path is confirmed, has long been recognized as a performance booster. However, it has also given rise to a class of vulnerabilities collectively known as “Spectre” attacks, where microarchitectural side states (such as the branch target buffer, caches, or predictor state) are mis-exploited to leak sensitive data.
Intel Begins Adding Nova Lake Xe3P To Linux OpenGL/Vulkan Drivers – Some Will Lack Ray-Tracing
Intel recently began sending out Xe3P kernel graphics driver patches for Nova Lake that will begin landing in the upcoming Linux 6.19 kernel cycle. Now on the user-space side, merged today for Mesa 26.0 were the first enablement patches for Xe3P Nova Lake for their open-source OpenGL and Vulkan drivers on Linux…

KDE Plasma 6.5’s Overlay Planes Support Yields Significant Power Savings
KDE KWin developer Xaver Hugl published a new blog post today outlining the KMS overlay planes support present within the newly-released Plasma 6.5 desktop. While not yet enabled by default, enabling the overlay planes functionality can result in some nice power savings such as during video playback…

[$] Safer speculation-free user-space access
The Spectre class of hardware vulnerabilities truly is a gift that keeps on
giving. New variants are still being discovered in current CPUs nearly
eight years after the disclosure of this
problem, and developers are still working to minimize the performance costs
that come from defending against it. The masked user-space access
mechanism is a case in point: it reduces the cost of defending against some
speculative attacks, but it brought some challenges of its own that are
only now being addressed.
