Along with the Linux 6.8 power management updates, maintainer Rafael Wysocki at Intel also sent in the ACPI updates for this next kernel version. While the ACPI changes for the kernel are often just routine churn, this cycle it's bringing a new feature: device enumeration for CSI-2 and MIPI DisCo for Imaging support. This will allow MIPI cameras moving forward to be enumerated via the platform firmware on ACPI-based systems...

AMD makes heavy use of the LLVM compiler infrastructure by their graphics drivers and compute stack while the GNU Compiler Collection (GCC) has to a lesser extent supported AMD graphics targets too in the context of GPU compute / OpenMP device offloading. That AMD Radeon/Instinct support for GCC has been carried out over the years by Mentor Graphics and other stakeholders. The latest on the AMD GPU expedition for GCC is that the upcoming GCC 14 compiler will finally be supporting AMD RDNA3 (GFX11) graphics hardware...

Making use of dmidecode is the go-to way of being able to read various DIMM memory information on Linux systems like the model number, speed, and other attributes. But sadly using dmidecode is restricted to root due to needing to access /dev/mem. But it turns out there is another less reported way to receive much the same information...

In recent days there have been leaks about an MSI "CLAW" gaming handheld device set to be announced this coming week at CES in Las Vegas. Making this gaming handheld device interesting is that unlike the Valve Steam Deck and ASUS ROG Ally or Legion Go, it's expected to be the first handheld featuring an Intel Meteor Lake SoC.
