The "intel_idle" driver provides CPU idle time management for Intel processors on Linux for helping to put the processor into low-power states in conjunction with the MWAIT instruction. With the upcoming Linux 6.13 kernel, the Granite Rapids D support for the Intel Idle driver is set to be merged.

It's the second Tuesday of the month and this Patch Tuesday brings new CPU microcode for mitigating the latest Intel processor security vulnerabilities and updates to some previously disclosed issues.

One of the many changes to look forward to with the upcoming Linux 6.13 kernel cycle is the AMD P-State driver to be used by default with the new EPYC 9005 series processors. While AMD Ryzen CPUs for a while now have been defaulting to the modern AMD P-State driver that makes use of ACPI CPPC platform support for allowing better power efficiency, AMD EPYC CPUs have kept to using the generic ACPI CPUFreq frequency scaling driver. But now AMD engineers have deemed amd_pstate ready for use with EPYC 9005 "Turin" CPUs and will be the default choice moving forward. Here is more information and power/performance benchmarks for this shift while testing using the EPYC 9755 processors.

Merged today to GNOME's Mutter compositor is improved logic for selecting the graphics processor to treat as the primary one within multi-GPU laptops.

Red Hat announced today they have signed a definitive agreement to acquire Neural Magic, an AI software company behind the likes of DeepSparse and nm-vllm.

As part of the transition to eventually drop the long dormant Clover OpenCL state tracker from Mesa's Gallium3D codebase in favor of the modern OpenCL Rusticl Rust-written driver, Mesa 25.0 has ended Clover support for NIR-based drivers.

Yesterday brought the eighth and ninth iteration of the AMD XDNA Linux kernel driver posted for review for enabling the Ryzen AI branded NPUs found in their recent SoCs.

Red Hat in cooperation with Intel, Bloomberg and IBM has been developing the Climatik open-source project as a means of power capping AI use within the data center for better energy efficiency and sustainability.

Merged today for the upcoming GCC 15 stable release is a new "X86_TUNE_AVX512_TWO_EPILOGUES" tuning optimization that is enabled by default for AMD Zen 4 and Zen 5 processors.

DXVK 2.5 was just released as the newest version of this open-source project implementing Direct3D APIs atop the Vulkan API for better handling of Windows games on Linux systems as used by Valve's Steam Play (Proton) software.

Memtest86+ 7.0 debuted back in January while now as we approach the end of 2024, Memtest86+ 7.20 is now available as the latest significant update to this open-source memory tester commonly used on Intel and AMD systems.

The latest terminology within the Fedora camp causing concern is "karma" that's long been used for conveying feedback around package updates with their Bodhi software used for gating Fedora Linux package updates.

Microsoft last month announced the open-source Rust-written OpenHCL for running confidential Intel TDX and AMD SEV-SNP virtual machines. Today Microsoft is announcing another interesting open-source, Rust-based project in the virtualization space: Hyperlight. Microsoft's Hyperlight project is an embed-friendly, lightweight VMM for use within Linux and Windows applications.

While not as exciting as if it were Apple M3/M4 device support hitting the upstream mainline Linux kernel, but for those with some older Apple (pre-M1) devices around, support for a number of older SoCs and boards is set to arrive with the upcoming Linux 6.13 kernel.

As another effort for boosting the energy efficiency and behavior of Intel Core platforms with a mix of energy efficient "E" and performance "P" cores, a set of patches were posted Friday night for adapting Energy Aware Scheduling (EAS) to the Intel P-State CPU frequency scaling driver with a focus on providing better energy efficient performance initially for Lunar Lake SoCs.

Set to be merged during the upcoming Linux 6.13 merge window is support with the Rust programming language infrastructure for allowing in-place kernel modules.

The Intel Diamond Rapids target has been merged in time for the upcoming GCC 15 compiler release to allow for "-march=diamondrapids" targeting for leveraging the array of new CPU ISA additions found with these next-gen Xeon processors.

The Rust-written Servo browser web layout engine project is out with its October 2024 status update that provides insight to their development activities the past several weeks.

PHPStan 2.0 is out today as what is the best open-source static analyzer for the PHP programming language.

Linus Torvalds just christened the Linux 6.12-rc7 kernel today for what will hopefully be the last release candidate before declaring Linux 6.12 stable next week Sunday.
