AMD CPU Microcode Loading On Linux Being Fixed Up To Be Per-Thread

Phoronix - 16. Srpen 2022 - 12:00
Up to this point loading updated CPU microcode on AMD processors under Linux has checked just to ensure every physical CPU core was loaded with the new microcode but not sibling threads for SMT processors. While logically that makes sense, it turns out some AMD microcode updates do carry out per-thread modifications that means the microcode updating needs to be carried out on every thread. A Linux fix is on its way to the kernel to adjust that behavior...

Qualcomm Posts "QAIC" DRM Accelerator Driver For Linux

Phoronix - 15. Srpen 2022 - 20:00
After Qualcomm announced their Cloud AI 100 Accelerator back in 2019, in 2020 during the early days of the pandemic they posted a Linux driver for this accelerator. That driver didn't get picked up for the mainline Linux kernel and two years later there still is little fanfare around the Qualcomm AI Cloud Accelerator hardware. However, now they have posted a new Linux driver that goes the DRM driver route...

Greg KH Recommends Avoiding Alder Lake Laptops - Intel Webcam Linux Driver Long Ways Out

Phoronix - 15. Srpen 2022 - 11:50
Greg Kroah-Hartman as the Linux kernel's stable maintainer and effectively Linus Torvalds' second-in-command has suggested avoiding Intel Alder Lake laptops. While much of the Alder Lake laptop support for Linux is in good shape, the exception is around web cameras. These newer laptops with Intel's latest web-camera tech are not currently supported by the mainline kernel and require proprietary software for use. Some platforms like Ubuntu and ChromeOS are picking up these blobs for now while a proper open-source, upstream solution is likely months -- or likely about one year -- away...
