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.

The x86/core changes for Linux 6.1 have been merged and are headlined by making sure an INT3 instruction is inserted after every unconditional Retpoline jump (JMP) for the Retpolines handling on both Intel and AMD processors...
