Linux ThinkPad Driver Ready For Reporting Damage Device - Starting With Bad USB-C Ports
Queued yesterday into the platform-drivers-x86.git's "for-next" branch are the patches for the Lenovo ThinkPad ACPI driver to begin reporting damaged device detection. This code being in the "for-next" branch makes it material for the next version of the Linux kernel and initially will be able to report to the user on damaged USB-C ports...
AMD EPYC 8004 "Siena" Shows Some Nice Linux Performance Gains Over The Past Two Years
As part of my various end-of-year benchmarks, recently I looked at the Linux LTS kernel performance on AMD EPYC 9005 over the past year, the AMD EPYC Milan-X performance over the past four years, and various other performance comparisons over time to look the evolution of the Linux software performance. Another run I had carried out was looking at the AMD EPYC 8004 "Siena" series since its launch just over two years ago. Here is a look at how an up-to-date Linux software stack can deliver some additional performance gains for these energy efficiency and cost-optimized server processors.
Linux 7.0 Looks To Enable Intel TSX By Default On Capable CPUs For Better Performance
A patch queued up into tip/tip.git's x86/cpu Git branch ahead of the upcoming Linux 6.20~7.0 kernel cycle enables the Intel Transactional Synchronization Extensions (TSX) functionality by default on the mainline kernel for capable CPUs and those not affected by side-channel attacks due to TSX Async Abort (TAA) and similar vulnerabilities. For newer Intel CPUs with safe TSX support, this change can mean better performance with the kernel defaults...
