RISC-V Developers Continue Working On KVM Support

Going on for more than one year now is the effort for supporting KVM virtualization with the RISC-V architecture, which is very much important for RISC-V processors to be able to eventually take lift in the server space. The KVM RISC-V enablement work is now up to its nineteenth revision but not yet clear if it's ready for mainlining.

BLAKE3 v1.0 Released - Faster & More Secure Than SHA-1, Etc

The BLAKE3 cryotpgraphic hash function that was announced last year and based on its predecessor BLAKE2 has now reached version 1.0 for its official/reference software implementation. BLAKE3 continues to be much faster than BLAKE2 while also being much faster than the likes of SHA-1/SHA--2/SHA-3 and even MD5 while being more secure.

Proposed Reflink Support Would Provide Big Space Savings For Wine

When sticking to Wine recommendations of maintaining separate prefixes per-application, a lot of system files get duplicated for each game/application and in turn leading to significant bloat. With the current state of Wine it can mean hundreds of megabytes per prefix in duplicated files. But proposed reflink patches for Wine are aiming to cut down on this severe bloat.

Ubuntu vs. Arch Linux On The ASUS ROG Strix G15 / Ryzen 9 5900HX

This past week were the initial Linux benchmarks of the Ryzen 9 5900HX with the ASUS ROG Strix G15 laptop. Ubuntu was used as the default test platform as usual given its popularity and arguably the most relevant Linux distribution to use given that it's the most common Linux distribution at the moment for preloads on laptops by multiple vendors. In any case, as usual many users were quick to say "but Arch Linux!" as if it was going to make a dramatic difference in my findings. Well, here are some Ubuntu 21.04 versus Arch Linux benchmarks on that AMD Advantage laptop.

Loongson 3A5000 Benchmarks For These New Chinese CPUs Built On The LoongArch ISA

While Loongson has been known for their MIPS-based Loongson chips that are open-source friendly and have long been based on MIPS, with MIPS now being a dead-end, the Chinese company has begun producing chips using its own "LoongArch" ISA. The first Loongson 3A5000 series hardware was just announced and thanks to the company apparently using the Phoronix Test Suite and OpenBenchmarking.org we have some initial numbers.

Trying Out The "Folios" Patches On An AMD Linux Server

One of the low-level exciting kernel advancements being worked on at the moment is the new "folios" struct for improving Linux memory management. Tests by those involved found that in some conditions Linux kernel builds for example could be up to 7% faster. Given the recent folios v14 patches being published, I took them for a spin on an AMD EPYC server to see the impact on overall performance.

Mesa RADV vs. AMDVLK Radeon Vulkan Performance For July 2021

It's been a while since last looking at the performance of AMD's official "AMDVLK" open-source Linux Vulkan driver against that of the popular Mesa "RADV" Radeon Vulkan driver. But here are some fresh benchmarks for those interested while using the latest-generation Radeon RX 6800 XT graphics card paired with the in-development Linux 5.14 kernel across testing both Vulkan drivers.
