IO_uring continues to be one of the most exciting technical innovations in the Linux kernel in recent years not only for more performant I/O but also opening up other doors for new Linux innovations. IO_uring has continued adding features since being mainlined in 2019 and now the newest proposed feature is the ability to build new ioctls / kernel interfaces atop IO_uring...

With a pending patch, the Linux 5.11 AMD Zen 2 / Zen 3 performance is looking very good as far as the out-of-the-box performance is concerned when using Schedutil as is becoming the increasingly default CPU frequency scaling governor on more distributions / default kernels. With the previously noted Linux 5.11 regression addressed from when the AMD CPU frequency invariance support was first introduced, the Schedutil performance from small Ryzen systems up through big EPYC hardware is looking quite good. But how much upside is left in relation to the optimal CPU frequency scaling performance with the "performance" governor? Here is a look at those benchmarks on Ryzen and EPYC for Schedutil vs. Performance on a patched Linux 5.11 kernel.

Finally with the upcoming Linux 5.12 cycle is support for Variable Rate Refresh (VRR) / Adaptive-Sync for Intel Tiger Lake "Gen12" Xe Graphics and newer...

Announced a few years ago was the notion of "extended" LTS kernel versions whereby the long term support cycle would span six years rather than the usual two years for LTS kernels in providing maintenance and bug/security fixes to the codebase. This means Linux 5.4 LTS is supported until the end of 2025, Linux 4.19 until the end of 2024, and even Linux 4.14 until the start of 2024. But with the recently minted Linux 5.10 LTS at least for now it's only being committed to maintenance until the end of next year...

Feature development on LLVM 12.0 has ended along with associated sub-projects like Clang and libc++. Feature work now shifts to LLVM 13.0 while the LLVM 12 stable release should be out in just over one month's time...

Nearly a decade ago we were intrigued by Unvanquished as one of the most interesting open-source game/engine projects of the time. It was peculiar in going through dozens of alpha releases prior to drying up a few years ago. There hasn't been any major release yet past the prior alpha state but the project is in fact still moving along and issued their first new (point) release of the year as well as rolling out a new online updater...

A few days ago we wrote about Linux 5.12 to see support for the Nintendo 64 more than two decades after that MIPS-based video game console first shipped. While the practicality of Linux on the Nintendo 64 is particularly limited given only 4~8MB of RAM and the MIPS64 NEC VR4300 clocked under 100MHz, it's going upstream and now the N64 controller driver is also queued for this next kernel cycle...

While the initial AMD Linux 5.11 performance regression written about at the end of last year was of much concern given the performance hits to AMD Zen 2 / Zen 3 processors with the out-of-the-box "Schedutil" governor, with a pending patch the regression is not only addressed but in various workloads we continue seeing better performance than even compared to Linux 5.10. Here is the latest from several more days of extensive performance testing.

Last year during the big round of layoffs at Mozilla the entire Mozilla Developer Network (MDN) writers team was laid off. That was a particularly sad blow considering how valuable the MDN documentation has been to web developers as a very useful resource. Today the Mozilla folks are announced Open Web Docs in seemingly looking to have the community take over...

Last quarter Intel began upstreaming their open-source Alder Lake S graphics support for Linux. It hasn't been too big of a feat or revealed many details since it's still Gen12 / Xe graphics seen since Tiger Lake. But it's been coming along and over the past month is now wired up into Intel's open-source Media Driver stack too...

Voltage, temperature, and fan speed reporting among desktop motherboards under Linux remains one of the unfortunate areas even in 2021... Many SIO ICs remain publicly undocumented and the Linux driver support is often left up to the community and usually through reverse-engineering. Thus the mainline Linux kernel support is left to suffer especially among newer desktop motherboards. At least for Linux 5.12 some ASRock motherboards will begin seeing their voltage/temperature reporting now function...

Pyston started out as a fork of CPython and was very promising during its early days as a Dropbox project for delivering on high performance Python. Its performance was great but in 2017 Dropbox stopped supporting it. Then at the end of 2020, Pyston reappeared and Pyston 2.0 promoted ~20% faster performance than Python 3.8. Pyston 2.x was developed by many of the original developers from Dropbox now out working on their own firm...

With the Zink OpenGL-on-Vulkan implementation within Mesa on a nice upward trajectory with most recently now having the backing of a Valve contract developer and a focus on getting the backlog of patches to this Gallium3D code upstreamed, here are some fresh benchmarks looking at where the performance currently stands when using Zink atop the RADV Vulkan driver compared to using the native RadeonSI driver with this round of testing from a Radeon RX 5700 XT graphics card.
