It's "Patch Tuesday" and Intel is out with new CPU microcode for Linux users in addition to making public 30 new security advisories that affect a range of Intel products.

Intel CPU microcode-20251111 was published today. The noted changes are for addressing a range of functional issues from 12th Gen Intel Core CPUs to newer, including 4th and 5th Xeon Scalable CPUs as well as Xeon 6 processors too.

Among the functional issues addressed are for Lunar Lake

The Linux kernel's Human Interface Devices (HID) subsystem has an existing architectural limitation that there is just up to one battery per HID device. But with modern devices -- especially among various gaming peripherals -- there can be more than one battery when considering earbuds with a battery for each earbud, multi-device wireless receivers, etc. A proposal was raised today to address this limitation.

Lucas Zampieri of Red Hat sent out the patch today proposing support for multiple batteries per HID devices to overcome this HID subsystem

While there is the AMD openSIL project for open-source CPU silicon initialization for platforms moving forward with plans to ultimately replace AGESA and be more friendly toward the likes of Coreboot, for those on aging AMD Bulldozer and Piledriver era platforms there is some updated open-source firmware available thanks to an independent free software project.

For those that don't remember or weren't around back in the 2011 timeframe, back then AMD was initially promoting Coreboot and putting out open-source AGESA code for the processors

Intel on Monday released version 0.1 of their Low Power Mode Daemon, the open-source daemon in development for several years now for optimizing active idle power on modern Intel Core (Ultra) CPUs under Linux.

Intel's Low Power Mode Daemon is useful for enhancing power efficiency under Linux and keeping power/thermals to a minimum during idle/low-power periods for processors featuring Intel's hybrid core design.

With the new Intel LPMD 0.1 release the only listed change is adding support for upcoming

System76 engineer Victoria Brekenfeld and Red Hat engineer Sebastian Wick presented at the recent XDC2025 developer conference with their hopes of finally fixing the multi-GPU experience on Linux. As part of this is getting the necessary Wayland protocols in order as well as a new gpu-daemon service for proper multi-GPU handling for the Linux desktop.

There are many known issues with the multi-GPU experience on Linux that can vary based upon driver and whether using X.Org or Wayland as well as what

New Linux kernel patches currently undergoing review will allow AMD Ryzen AI NPU power metrics to be exposed under Linux. In turn this is useful for helping to gauge the utilization of the neural processing unit and also helping to evaluate the actual power efficiency of leveraging the AMD Ryzen AI NPU.

Linux enabling the AMD Ryzen AI NPU was off to a slow start in the first place with the the AMD XDNA Linux driver code having not been posted until nearly a year after the Ryzen 7040 series launch , several months after

The YouTube video recordings for the X.Org Developers' Conference 2025 that took place at the end of September in Austria are finally available. Among the many interesting XDC2025 presentations was Intel engineer Matthew Brost talking about the GPU Shared Virtual Memory (SVM) within Intel's modern Xe kernel graphics driver.

Shared Virtual Memory (SVM) and Heterogeneous Memory Management (HMM) shouldn't be anything new for longtime Phoronix readers or in regards to Intel their ongoing work in that area with
