Linus Torvalds Demotes "FORCE_NR_CPUS" Embedded Linux Option To Avoid Confusion
Linus Torvalds Demotes "FORCE_NR_CPUS" Embedded Linux Option To Avoid Confusion
7 Hours Ago - Linux Kernel - FORCE_NR_CPUS - 2 Comments

The Linux kernel "FORCE_NR_CPUS" Kconfig option has been around a few years to force the number of CPU cores the kernel expects in order to allow for better compiler optimizations. When building a kernel targeted for a specific device/platform with a given number of CPU cores, the compiler can optimize CPU mask routines and shrink the size of the resulting kernel image rather than having to accommodate up to a dynamic upper-limit for the number of CPU cores to be found at boot time. Linus Torvalds himself has turned to demoting this CONFIG_FORCE_NR_CPUS option further to avoid confusion.

Announced back in March by the Linux Foundation was Valkey as a Redis fork following upstream licensing changes. In the few months since the Valkey in-memory NoSQL data store has put out its first release and has continued attracting more interest from Linux/open-source communities. Today the Linux Foundation announced another handful of organizations now throwing their weight behind Valkey.

PoCL 6.0 OpenCL Implementation Brings OpenMP For CPU Driver, More Remote Driver Features
PoCL 6.0 OpenCL Implementation Brings OpenMP For CPU Driver, More Remote Driver Features
18 June 08:48 AM EDT - Programming - Portable Computing Language 6.0 - Add A Comment

The Portable Computing Language "PoCL" that started off as a CPU-based OpenCL implementation has grown to support multiple hardware targets from NVIDIA PTX to Intel Level Zero to AMD ROCm and other innovations like a recent remote driver for transparent OpenCL across networked systems. PoCL 6.0 was released today for delivering the latest enhancements to this independent OpenCL compute implementation and continuing to enhance support for its different hardware targets.

Marek Olšák Lands Support In Mesa 24.2 To Vectorize IO In The GLSL Linker
Marek Olšák Lands Support In Mesa 24.2 To Vectorize IO In The GLSL Linker
18 June 08:23 AM EDT - Mesa - Vectorize IO - Add A Comment

Well known AMD Mesa developer Marek Olšák has shown no signs of hitting the end of the road for optimizing OpenGL support within the Mesa/Gallium3D driver stack. More than one decade since joining AMD and more than a decade and a half of being involved with Mesa since beginning as a student developer, Marek still isn't slowing down with his performance optimizations and new features to benefit the open-source Radeon Linux graphics drivers.

New Linux Patches To Help Ensure Intel Xeon Servers Can Achieve Highest Frequencies
New Linux Patches To Help Ensure Intel Xeon Servers Can Achieve Highest Frequencies
18 June 07:04 AM EDT - Intel - Hitting Top Frequencies - 1 Comment

A set of patches for the Linux kernel's Intel P-State driver aim to ensure Intel Xeon servers can hit their highest clock frequencies following changes in the server's performance profile. It turns out some special handling is needed to update the highest frequencies of a CPU after boot to ensure the performance profile is properly reflected.

Linux's New DRM Panic "Blue Screen of Death" In Action
Linux's New DRM Panic "Blue Screen of Death" In Action
16 June 06:48 AM EDT - Linux Kernel - Linux Blue Screen of Death - 78 Comments

After being talked about for years of DRM panic handling and coming with a "Blue Screen of Death" solution for DRM/KMS drivers, Linux 6.10 is introducing a new DRM panic handler infrastructure for being able to display a message when a panic occurs. This is especially important for those building a kernel without VT/FBCON support where otherwise viewing the kernel panic message isn't otherwise easily available.
