KDE Plasma 6.1 Performing Much Better On Older Intel Integrated Graphics

25 juin 2024 à 15:01
With the recently released KDE Plasma 6.1 desktop environment, those still relying on old Intel integrated graphics should have a much more pleasant experience thanks to improvements made to the KWin compositor. For very old Intel integrated graphics, it can effectively be a night and day difference upgrading to the new Plasma 6.1 desktop...

Intel's Linux Software Optimizations Still Pay Off For Xeon 6700E "Sierra Forest" E-Core CPUs

25 juin 2024 à 13:48
When testing Intel's aggressive software Linux optimizations shipped by way of their in-house Clear Linux distribution, I am most often testing it on their high core count Xeon processors with AVX-512... Over the years in dozens of Phoronix articles there have been countless metrics showing off the out-of-the-box performance benefits from leveraging software built for higher x86_64 micro-architecture feature levels, employing compiler-based function multi-versioning, and the other extensive performance tuning carried out by Intel software engineers. But now with the Intel Xeon 6700E "Sierra Forest" series now being available for these all-E-core server processors, I was curious about quantifying the Clear Linux benefits over the likes of Ubuntu Linux. Here are those benchmarks for those curious about the difference.

More AMD P-State Driver Improvements Queued For Linux 6.11

25 juin 2024 à 10:49
Earlier this month AMD Fast CPPC support was queued into the Linux power management subsystem's "-next" codebase ahead of the Linux 6.11 cycle. Additional AMD P-State driver enhancements are now deemed ready and submitted for staging ahead of next month's Linux 6.11 cycle kicking off...

Fedora 41 Installer Proceeding To Transition From X11 To Wayland App

25 juin 2024 à 10:08
With Fedora's new web-based installer UI being delayed to 2025 with Fedora 42, part of Red Hat's justification for that setback was needing to invest resources first in Fedora 41 by transitioning the OS installer to being a native Wayland application. The Fedora Engineering and Steering Committee (FESCo) has now signed off on that work as expected to make the Anaconda OS installer a native Wayland application...

Out today is Llamafile 0.8.7 with more performance optimizations and new features...

Intel P-State Patches Further Tune Linux For Better Scheduling On Hybrid CPUs

24 juin 2024 à 14:00
A new set of patches are currently being tested for improving task scheduling and in turn performance for modern Intel Core hybrid processors. With the patch also mentioning systems that are hybrid but without SMT, this looks like it may be some early tuning as well for upcoming Intel Lunar Lake processors that lack Hyper Threading...

Amazon Exploring MM-Local Memory Allocations To Help With Current/Future Speculation Attacks

23 juin 2024 à 13:42
Back in 2019 after various speculation-based CPU vulnerabilities began coming to light, Amazon engineers proposed process-local memory allocations for hiding KVM secrets. They were striving for an alternative mitigation for vulnerabilities like L1TF by essentially providing some memory regions for kernel allocations out of view/access from other kernel code. Amazon engineers this week laid out a new proposal after five years of ongoing Linux kernel improvements for MM-local memory allocations for dealing with current and future speculation-based cross-process attacks...
