Making it into the RADV Vulkan driver ahead of this week's Mesa 25.2 feature freeze is experimental support for the VK_EXT_host_image_copy extension. The Vulkan host image copy extension was worked on by Valve and others for letting applications/games copy data between the host memory and images on the host processor without having to first stage via a GPU-accessible buffer...

The LTTng tracing toolkit is twenty years old this year and it's seen significant adoption by different hyperscalers and other notable organizations like IBM and Sony and Siemens beyond basic end-users and administrators for system tracing/debugging. While having many successes over the past two decades, the kernel modules remain outside of the kernel tree. Even with around four different upstreaming attempts to get the LTTng code into the mainline kernel, it still has not happened. A fifth attempt began today but still looks like it could be an uphill battle...

Last week I published fresh benchmarks showing how AMD's EPYC 4005 series for budget servers can outperform the original EPYC 7601 flagship processor when EPYC first launched during the Zen 1 period. Even with lower core counts and fewer memory channels, the modern EPYC 4005 "Grado" processors were able to outpace that original EPYC "Naples" flagship processor from 2017. With carrying out the fresh re-testing of the AMD EPYC 7601 on a modern 2025 Linux software stack, in today's article is a look at how the EPYC 7601 Zen 1 performance compares to the EPYC 9005 "Turin" series with today's flagship EPYC 9755 and EPYC 9965 processors.
