While Wine 10.0 recently debuted with the initial Wine Wayland driver, that native Wayland support is still in early form with various limitations and yet-to-be-implemented features... One of the newly-opened merge requests for filling in another gap is clipboard support for the Wine Wayland driver...

Red Hat engineers have been working on Nova as an open-source driver successor to the Nouveau driver for upstream NVIDIA GPU support within the Linux kernel that can be used with the Mesa OpenGL/Vulkan drivers. Unlike the prior larger RFC patch series, sent out to the Linux kernel mailing list today were some small patches for introducing "NOVA-Core" that would serve as the initial base for this modern NVIDIA Linux kernel DRM driver. Over time and succeeding kernel releases, the NOVA code would be built up until ultimately becoming a usable state for end-users...

While we are approaching the end of the Linux 6.14 merge window with Linux 6.14-rc1 expected on Sunday, the fun isn't over quite yet...

Back in October following the launch of the EPYC 9005 "Turin" processors I ran an AVX-512 performance comparison for the EPYC 9755 with 512-bit data path vs. 256-bit data path vs. AVX-512 disabled. That was interesting for showing the benefits of Zen 5's full 512-bit data path support compared to the "double pumped" approach with Zen 4 or optionally used via a BIOS option on Zen 5. AVX-512 continues to prove to be very performant and power efficient with AMD Zen 5 processors unlike with the early generations of AVX-512 on Intel processors. Here is a fresh look at the AVX-512 performance on a Supermicro server with an AMD EPYC 9655 processor.

Earlier this month the Raspberry Pi 5 16GB was announced for finally pushing the Raspberry Pi single board computers beyond an 8GB limit for RAM. This opens up the Raspberry Pi 5 to new use-cases, more multi-tasking, and other applications where 8GB of RAM / 2GB per core was a bottleneck. In my tests thus far of the Raspberry Pi 5 16GB it's been working out well and helping the performance of some workloads by reducing the memory pressure / swapping.
