The Linux 6.12 kernel cycle later this year has a change coming that will impact users of the "Schedutil" CPU frequency scaling governor. This change is dropping the "LATENCY_MULTIPLIER" that has been within the kernel code the past two decades to slowdown how frequent the CPU frequency evaluation occurs. In turn the revised logic can allow for that CPUFreq frequency re-evaluation to occur more often...

Like most modern Intel and AMD laptops, the new ASUS Zenbook S 16 models for the AMD Ryzen AI 300 series "Strix Point" support ACPI Platform Profiles for allowing the system platform behavior to be modified depending upon whether you are seeking maximum performance, balanced (default), or power savings/efficiency. With the Ryzen AI 9 365 and Ryzen AI 9 HX 370 testing I have been doing thus far it's been on the default balanced mode (along with other laptops being compared) while in this article is a look at the Ryzen AI 9 HX 370 performance impact on the ASUS Zenbook S 16 UM5606WA when trying the other platform profile options.

Microsoft is today promoting the v3.0 release of Azure Linux to stable / general availability status for this Linux distribution formerly known as CBL-Mariner...

There's been no shortage of cheap, ARM-based handheld game consoles coming to market. Given Linux on Arm tending to work better than Windows and in keeping vendor costs to a minimum, they've tended to be running Linux or Android with various open-source games/emulators. Many of the vendors have kept their Linux support downstream while with time more of these gaming handheld consoles are seeing mainline Linux support. Yet another one being worked on for mainline Linux kernel support is the GameForce Ace...
