Qualcomm QUPv3 Firmware Upstreamed For Snapdragon X1 Elite Linux Users

One of the headaches right now when dealing with the Snapdragon X Elite on Linux is that for a majority of the devices you need to fetch firmware files from the Windows 11 on ARM partition as the necessary firmware bits for Linux use aren't upstreamed to linux-firmware.git. That has gradually improved over time from the qcom-firmware-extract making the process easier to more firmware bits eventually being added to linux-firmware.git...

Linux Kernel Runtime Guard Reaches 1.0: A Major Milestone for Runtime Kernel Security

by George Whittaker The Linux security landscape just reached an important milestone. Linux Kernel Runtime Guard (LKRG) has officially hit version 1.0, marking its transition from a long-running experimental project into a mature, production-ready security tool. For administrators and security-conscious users, this release reinforces LKRG’s role as a powerful additional layer of defense for Linux systems. After years of development, testing, and real-world use, the 1.0 release signals confidence in LKRG’s stability, compatibility, and long-term direction. What Is LKRG? LKRG is a loadable kernel module designed to protect the Linux kernel at runtime. Instead of relying solely on compile-time hardening or static security features, LKRG actively monitors the kernel while the system is running. Its goal is to detect unauthorized changes, suspicious behavior, and exploit attempts that target kernel internals. Because it operates at runtime, LKRG complements existing protections like SELinux

New Raspberry Pi 4 models splits RAM across dual chips

A new version of the Raspberry Pi 4 Model B has been (quietly) introduced. The key difference? It now uses a dual-RAM configuration. The Raspberry Pi 4 Model B Rev 1.5 adopts a dual-RAM configuration to ‘improve supply chain flexibility’ and manufacturing efficiency, per a company product change notice document. Earlier versions of the Raspberry Pi 4 (v1.1 through 1.4) use a single RAM chip on the top of the board. This new revision adds a second LPDDR4 chip to the underside, with some passive components also moved over. Why use dual-RAM? Even those living under rocks will know that […]
