Linux 5.15 Is Now Slightly Less Broken For The DEC Alpha "Jensen"

One has to wonder how much longer the Linux kernel will keep around some very old and known to be borked hardware support but at least for now the DECpc AXP 150 "Jensen" platform support is sticking around and with Linux 5.15 is no longer marked as "broken" outright.

The Increasing Importance Of ACPI Platform Profiles With Today's Throttle-Happy Hardware

As covered several times going back to the end of last year, ACPI Platform Profile support has materialized in recent versions of the Linux kernel for the core infrastructure and implementations that work with the latest laptops from the likes of Dell, Lenovo, ASUS, and HP. This platform profile support is becoming increasingly important with expressing your power/cooling/performance preference so that your laptop behaves as one would expect.

Privacy-Screen DRM API With Intel Support Ready Now That GNOME Is Prepared To Use It

Over the past two years we have seen work around bringing up privacy screen support on Linux whereby an increasing number of laptops can reduce the amount of visible light when viewed at wide angles to try to block the screen contents from anyone potentially snooping at the screen. Ready to go now is the DRM/KMS user-space interface and the Intel graphics driver support now that there is a user-space "client" ready.

High Resolution Scrolling On Linux Progressing, Apple Magic Mouse Support In Linux 5.15

Being worked on for several years now on the Linux desktop has been high resolution scrolling including work for it around X Input, the libinput library used both by X.Org and Wayland systems, and the kernel driver side for the HID/input devices to support it. The latest user-space work is high resolution scroll wheel support within the next libinput release. Separately, with Linux 5.15 is now additionally support for high resolution scrolling with the Apple Magic Mouse.

Linux Could Use A New Maintainer For Its CD-ROM Code

Current Linux block subsystem maintainer Jens Axboe started out in the late 90's taking over maintainership of the Linux kernel's CD-ROM driver code. However, as he's busy these days with IO_uring and other prominent I/O activities for Linux, he's hoping someone interested and capable would want to take over the Linux kernel's CD-ROM code.

Habana Labs' Linux AI Driver Causes More Concerns - Changes Dropped Ahead Of Linux 5.15

While Habana Labs has been known for their open-source and upstream Linux kernel driver for their AI training/inference accelerators with that code they had been working on as a start-up even before being acquired by Intel, it's continued to cause friction that they rely in user-space on closed-source components like their compiler. That in turn is again causing problems for changes that the Habana Labs kernel driver planned to land with the upcoming Linux 5.15 cycle.
