Marek Olšák Scores Up To 100% Pixel Throughput Optimization For RADV Driver
Marek Olšák who had been a longtime AMD Linux driver engineer specializing in the RadeonSI Gallium3D driver, recently began working for Valve on their Linux graphics driver team. His focus has understandably shifted to working on the RADV Vulkan driver and one of his early optimizations now with the Valve hat on is up to a 100% pixel throughput optimization for the RADV driver, which is already quite well optimized thanks to years … ⌘ Read more

Benchmarking The Different CachyOS Linux Kernel Flavors
CachyOS ships with a good Linux kernel configuration by default balancing the different features as well as performance. But they also ship a variety of other kernel builds for those preferring a more leading-edge kernel or the current LTS series, a hardened kernel configuration, and more. In this article are some fresh benchmarks of the Arch Linux based CachyOS Linux distribution with some of its main kernel flavors. ⌘ Read more

[$] Trying to make sense of package-manager metadata
Package managers for operating systems and programming languages have been
around for decades. Each package manager, and its accompanying packaging format,
has been shaped by the needs of its respective ecosystem, but there is a growing

example, in vulnerability scans, software bills of materials (SBOMs), and more. On

[$] Representing the true signatures of kernel functions
Optimizing compilers can, under some circumstances, infer when a parameter to a

[$] Reconsidering x32 — again
The x32 ABI was meant
to be the best of both worlds, providing the expanded registers and

memory use of 32-bit systems. The Linux kernel has supported x32 since the
3.4 release in 2012. The initial excitement around x32 did not last,
though, and kernel developers are considering removing that support — and
not for the first time. Even the most unloved features tend to have a few
