The Linux 6.2 Direct Rendering Manager (DRM) open-source kernel graphics/display driver changes have been merged with a few notable feature additions for users this cycle...

Released on Sunday was Linux 6.1 and in addition to having many new features making it all the more exciting is that it's expected to be this year's Long-Term Support (LTS) kernel release. As such it will see widespread adoption particularly among servers and much interest from the hyperscalers. For those weighing an upgrade from last year's Linux 5.15 LTS kernel, Linux 6.1 with initial testing on an AMD EPYC Milan-X 2P server has shown a nice speed bump is possible across a wide-range of workloads.

As outlined yesterday the Radeon RX 7900 series can work on the upstream, open-source Linux driver stack if using Linux 6.0+ and Mesa 22.2 (but ideally 22.3+).

Back in 2020 the Linux kernel added a split-lock detector since when they occur an atomic instruction spanning multiple cache lines and requiring a global bus lock is needed. This has an unfortunate heavy impact on the system and thus the detector was added to report it to the kernel log when a split-lock occurs. But earlier this year starting with Linux 5.19, kernel developers decided to "make life miserable" and intentionally slow down bad behaving apps that abuse split-locks. That in turn has caused problems for some games -- so far select Windows games running under Steam Play -- and thus a new kernel knob is being added to more easily adjust the behavior...
