Linux Prepares To Support Microsoft's "Turn On Display" DSM To Address Laptop Issues

Microsoft in Windows 11 22H2 introduced a new ACPI Device Specific Method (DSM) "Turn On Display" notification that the Linux 7.0 kernel will be adding support for in dealing with some otherwise problematic laptop behavior.

Queued up into the Linux power management subsystem's "linux-next" Git branch ahead of the upcoming Linux 6.20~7.0 kernel cycle is support in the s2idle driver for invoking the Microsoft Turn On Display DSM. Microsoft's documentation describes

Git 2.53 Released With More Optimizations, One Step Closer To Making Rust Mandatory

While we might see Git 3.0 released around the end of 2026 , Git 2.53 is out today as the latest feature release and continuing to make changes with an eye toward that big Git 3.0 milestone.

Git 2.53 brings more performance optimizations for different Git sub-commands/operations, improved error messages, improvements to various Git sub-commands, and many bug fixes.

The full list of Git 2.53 changes can be found via today's

Security Researchers Find Current RISC-V CPU Implementations Coming Up Short

While many open-source enthusiasts like to flaunt RISC-V as not having the security challenges as x86_64 CPUs have seen over the past several years with various speculative execution / side-channel attacks and arguing for the benefits of an open-source ISA in stronger security, in practice it's not so clear-cut. Security researchers at Germany's CISPA Helmholtz Center for Information Security have found current RISC-V CPU implementations coming up short for their actual security.

Loongson 3B6000 Benchmarks: How China's LoongArch CPU Compares To AMD Zen 5, Intel Arrow Lake & Raspberry Pi 5

Recently I finally got my hands on a LoongArch processor, the ISA developed by China's Loongson Technology as an evolution from their earlier use of the MIPS64 ISA and inspired by RISC-V and other modern ISAs. The Loongson-3B6000 features 12 cores / 24 threads with dual channel DDR4 ECC memory support. Here is a look at how that latest-generation LoongArch desktop processor compares to the current generation AMD Zen 5 and Intel Arrow Lake desktop processors under Linux.

Experimental Linux Code For 1GB PUD-Level THPs Shows 34% Faster Memory Access Times

Early, experimental code for implementing 1GB PUD-level THPs in the Linux kernel are showing positive benchmark results but other upstream stakeholders were surprised by this patch series appearing and it looking like it could be a while until if/when the patches are mainlined for helping to reduce translaction lookaside buffer (TLB) pressure without resorting to Hugetlbfs.

Usama Arif posted a request for comments (RFC) patch series on 1GB Page Upper Directory (PUD) Transparent Huge Pages (THP) support. The intent with this work is

Rust Coreutils Continues Working Toward 100% GNU Compatibility, Proving Trolls Wrong

Sylvestre Ledru who serves as the lead developer of the uutils project for the Rust Coreutils implementation presented at FOSDEM 2026 this weekend on this initiative. Ledru has spoken at FOSDEM in prior years on Rust Coreutils and this year's talk focused primarily on Ubuntu 25.10's adoption of it in place of GNU Coreutils.

Ledru's presentation covered the progress made on Rust Coreutils in recent times and Ubuntu 25.10's uptake of Rust Coreutils and continuing that for Ubuntu 2

Intel ISH Firmware Upstreamed For Linux With Dell's New Panther Lake Laptops

Ahead of Dell's new XPS 14 and XPS 16 laptops powered by Intel Core Ultra Series 3 " Panther Lake " expected to be shipping in volume beginning in March, more of the Linux support for these premium Panther Lake laptops continues to be finished up.

Last week was upstreaming the firmware files needed for audio support on the new Dell Panther Lake XPS laptops. Now another bit of firmware has been upstreamed for enabling the Intel Integrated Sensor Hub (ISH) on the Dell Panther Lake hardware. The ISH is

Linux From Scratch Abandoning SysVinit Support

Linux From Scratch was one of the holdouts continuing optional SysVinit init system support through 2026, but that's now ending. Linux From Scratch "LFS" and Beyond Linux From Scratch "BLFS" are ending their System V Init support moving forward.

LFS/BLFS will not be supporting System V in future versions due to the increasing demands of continuing to maintain and test both System V and systemd support. LFS/BLFS is a volunteer effort and continuing to maintain the SysVInit support is a burden. Additionally

Raspberry Pi Raises Prices As Much As $60 Due To Memory Demand

Last year Raspberry Pi announced price increases due to memory demand . Today they have announced another round of increased prices as a result of the memory shortages going on industry-wide.

Raspberry Pi is having to raise prices once again due to memory prices continuing to soar in 2026. This affects all their Raspberry Pi 4 and 5 and Compute Module 4 and 5 products with at least 2GB of memory. At least for the Raspberry Pi Zero and Raspberry Pi 3 they still have "several years' inventory"
