For the past number of months there has been talk in the Ubuntu developer space around replacing initramfs-tools with Dracut for handling initrd generation. While there has been progress in switching to Dracut, they aren't over the finish line yet and not until Ubuntu 25.10 are they planning to use Dracut by default...

Adding to the excitement around the possibilities provided by the in-kernel eBPF Linux tech, Meta shared that their Strobelight software they are working on open-sourcing for profiling across servers has yielded a 20% reduction in CPU cycles and in turn a 10-20% reduction in the number of required servers for Meta’s top services...

SiFive recently sent over a review sample of the much anticipated HiFive Premier P550 developer board, their newest RISC-V creation featuring four RISC-V cores, Imagination AXM-8-256 integrated GPU, Gigabit Ethernet, PCIe x16 slot, and 16GB or 32GB of RAM. The HiFive Premier P550 is a modern RISC-V developer board capable of desktop uses, developer build boxes, and similar with pricing starting out at $399 USD. Here is a look at the SiFive HiFive Premier P550 as well as comparison benchmarks of this RISC-V board to the popular Raspberry Pi single board computers.

SiFive recently sent over their new HiFive Premier P550 developer board and as part of that fresh RISC-V CPU testing I've also been re-testing the prior SiFive HiFive Unmatched developer board from 2020~2021 for reference. Out of curiosity, I've carried out some tests using the HiFive Unmatched to look at how the Ubuntu Linus RISC-V performance has evolved from Ubuntu 21.04 when I first tested that RISC-V quad-core developer board, Ubuntu 22.04 LTS, and now the latest Ubuntu 24.04 LTS packages.

Back in December Linux kernel patches were posted by a Meta engineer for making use of the AMD INVLPGB instruction found with Zen 3 and newer processors. The Linux kernel would use INVLPGB for invalidating TLB entries for a range of pages with broadcast. After these patches went through 14 rounds of review since December, it looks like this AMD broadcast TLB invalidation support is now ready for the mainline Linux kernel!..
