When booting the Linux kernel using UEFI SecureBoot, the kernel is put in the lockdown mode to restrict the ability to modify the running kernel image or leaking data from kernel memory. Kernel lockdown mode can also be manually enabled by the user/administrator. Among the limitations imposed in Linux's lockdown mode is no hibernation support. But that soon may be relieved with new patches proposed...

When it comes to Linux pre-loaded laptops, I have looked at hardware from most of these vendors over the past 22+ years of Phoronix. One vendor I haven't had the chance to personally test until now is the UK-based Star Labs. That changed recently and over the past few weeks I have been testing out their new StarFighter laptop that offers great Linux support and comes pre-loaded with Coreboot and streamlined firmware updates via LVFS. For those after a high-end mobile workstation, the Star Labs StarFighter offers a lot of performance potential while being open-source friendly and with Coreboot in tow.

While most everyone understandably likes to talk about AI these days, one of the areas of NVIDIA's Vera CPU I have been most eager to test has been for conventional high performance computing (HPC) workloads. HPC was talked up as one of Vera's strengths thanks to its 1.2TB/s LPDDR5x memory bandwidth and custom Olympus cores. Vera is seeing deployments at HPC labs like Los Alamos. With recently having unfettered remote access to a dual NVIDIA Vera server, I ran through a variety of HPC workloads and similar performance benchmarks. Here is a look at how NVIDIA Vera performs against AMD EPYC and Intel Xeon, including with CPU power and frequency metrics.
