Laptop Improvements With Linux 5.14 Benefit Lenovo, Dell, Microsoft Surface Devices
The x86 platform driver updates have been submitted for the in-development Linux 5.14 kernel. This area of the kernel principally benefits x86 laptop support on Linux but also has other drivers like around the Intel Speed Select Technology and more.
This cycle there are some exciting additions to the Lenovo ThinkPad and Dell device support as well as continuing to improve the open-source (community-driven) Microsoft Surface support:
- The Think-LMI driver has been queued for changing BIOS settings from within Linux using the firmware-attributes sysfs area on newer Lenovo systems including ThinkPad laptops. This is a fun addition and the sysfs firmware-attributes support and initial driver for controlling BIOS settings from within Linux having been spearheaded recently by Dell.

Radeon Software for Linux 21.20 Released - Phoronix
Quietly released last week by AMD was their Radeon Software for Linux 21.20 driver providing the latest packaged "Open" and "PRO" (Closed) driver components for use within enterprise Linux environments.
Radeon Software for Linux 21.20 is their first public packaged driver update since April when Radeon Software for Linux 21.10 debuted with initial support for Vulkan ray-tracing.
The public change-log for the Radeon Software for Linux 21.20 mentions RHEL / CentOS 8.4 and SUSE Linux Enterprise 15 SP3 operating system support. No other changes are mentioned but both the Open and PRO driver components should be updated against their more recent upstream and internal states, so it's worth testing to see what all might be changed. In particular, we are eager to test Radeon Software for Linux 21.20 to see if the Vulkan ray-tracing support and performance is in any better standing. Stay tuned for tests.
