One of the rather elusive items on the Linux desktop is High Dynamic Range (HDR) display support... There's been code in the works for years but across desktops and drivers, it's still a long-term effort getting HDR support on the Linux desktop. Even going back to 2016, with NVIDIA's cross-platform driver code the Linux desktop remained the bottleneck. There is at least some ongoing work to address this long-term issue with AMD this week presenting on the topic...
Merged last month into Mesa 22.3 was Rusticl as a Rust-written OpenCL implementation for Gallium3D that is beginning to work with the open-source Radeon Linux driver, the Intel "Iris" Gallium3D driver, and others. This is also the first Rust-written component within the Mesa code-base. Karol Herbst of Red Hat who has led Rusticl development presented this week in Minnesota on this promising cross-vendor OpenCL implementation that may also support SYCL in the future...
Last week at Intel's Innovation conference the Intel Developer Cloud "DevCloud" was announced, while on the AMD side there is already something similar: the AMD Cloud Platform. At the tail end of 2021, AMD announced the Accelerator Cloud as a way for trying out the latest EPYC CPUs and Instinct accelerators complete with a pre-configured ROCm compute software stack. The AMD Cloud Platform is a currently parallel effort to the Accelerator Cloud with the former intended more for developers while the latter is more customer-oriented. After trying out the AMD Cloud Platform, it's indeed an easy way to evaluate the latest AMD data center wares while having a easy-to-deploy, pre-configured software environment.

The real-time "RT" mainlining effort for the Linux kernel remains ongoing. While the finish line is coming near, PREEMPT_RT support for mainline still isn't over the last hurdle -- seemingly the main blocker it's still held up by are the printk changes with threaded console printing. But for the Linux 6.1 merge window there is at least more kernel code clean-ups...
Today the embargo lifts on reviews of the Intel Arc Graphics A750 and A770 graphics cards ahead of their retail availability set for next week. I've had the A750 and A770 at Phoronix the past week and today can share initial performance figures on these Intel DG2/Alchemist discrete graphics cards under Linux with their open-source driver stack.

I always love pull requests that start off with "there's a bunch of performance improvements..." as is the case with the new Btrfs feature pull for Linux 6.1...
Last week I shared some initial numbers how surprisingly when disabling Zen 4 CPU security mitigations can actually *hurt* the Ryzen 7000 series CPU performance. While conventional wisdom and with past Intel/AMD processors yield better performance when disabling the CPU security mitigations, with the Ryzen 9 7950X it was found to be basically the opposite. I have since conducted more tests and using an AMD Ryzen 5 7600X to confirm the earlier results and dig deeper into the data.
As a follow-up to the Rust infrastructure pull request for Linux 6.1, Linus Torvalds pulled the initial Rust code into the mainline Linux kernel this evening...
Git 2.38 was released on Sunday and most notable with this feature release is the inclusion of scalar as a Microsoft-developed repository management tool to make it easier dealing with very large Git reposotories...
A kernel hardening security improvement on the way for Linux 6.1 is the ability to provide warning of possible memcpy() based overflows. Right now this is only a warning but it's work towards being able to address "trivially detectable" buffer overflow conditions within the kernel and in the future may be able to block such overflows from happening...
Before getting busy with the AMD Ryzen 7000 "Zen 4" desktop testing, I recently wrapped up some benchmarks looking at the ACPI CPUFreq vs. AMD P-State frequency scaling drivers and various governor options for the AMD Ryzen 6000 "Rembrandt" mobile SoCs. If you are curious about the impact of CPUFreq/P-State and the various governors for the latest AMD laptops running Linux, this round of testing is for you.
