The GNU C Library 2.33 release is out today as expected. Exciting with this libc update is HWCAPS in making it easier to load optimized libraries for modern CPUs...

With Ubuntu 21.04 planning to use Wayland by default with GNOME aside from when running on NVIDIA graphics, you may be wondering about the current performance delta between running GNOME Shell on the X.Org session for Linux gaming versus its quite solid Wayland support. Or, rather, in the case of most games still - piped through XWayland. Here are some fresh benchmarks looking at the GNOME X.Org vs. Wayland performance on Ubuntu with the Radeon RX 6800 XT.

While Qt 6.0 wasn't even released a full two months ago, the Qt 6.1 feature freeze went into effect this morning in trying to get out this next update sooner...

In the works over the past year for the GNOME desktop environment is dynamic triple buffering when the GPU is running behind in rendering the desktop. In doing so, the GPU utilization should increase and the GPU clock frequencies in turn should ramp up to meet the demand - thereby ideally getting the rendering back on track if prior frames were running late. That triple buffering support has been re-based to the GNOME 40 code-base but still is unlikely to land until the next cycle with GNOME 42...

Two years ago patches were posted in working on Wine support for IBM POWER / OpenPOWER hardware. The aim with that enablement has been to run Windows programs on POWER 64-bit hardware via Wine with the related "Hangover" project for handling the cross-architecture difference. The Wine patches for PPC64 have now been revived with hopes of mainlining them now that Wine 6.0 has passed...

For those wondering how say AVX heavy a particular program is being benchmarked or if a given program/benchmark supports making use of new instruction set extensions such as Vector AES or forthcoming AVX VNNI or AMX, the Phoronix Test Suite and OpenBenchmarking.org can now provide that insight on a per-test basis with common CPU instruction set extensions...

Bareflank is an open-source Linux hypervisor in development for several years and written around modern C++11/C++14 code and other modern functionality compared to longstanding virtualization hypervisors. Over the past few years it's been picking up many new features while this week Bareflank 2.1 released prior to a major overhaul coming with Bareflank 3.0 that will radically change the codebase...

Last year the Linux kernel began tightening up the ability to write to select CPU MSRs from user-space. That restricting of user-space access to select registers was done in the name of security as well as not wanting user-space to accidentally or maliciously poke some MSRs that could cause problems with kernel behavior. Now in kernel space there are some yet-to-be-merged patches that would place some new restrictions on kernel modules around poking certain registers or using select CPU instructions...

While the AMD Linux graphics driver for some time has been supporting FreeSync over DisplayPort connections, FreeSync displays connected via HDMI have not been supported. But now we are finally seeing the start of patches at least as far as HDMI pre-v2.1 support is concerned...

Added to the GNU Compiler Collection (GCC) last year was an integrated static analyzer via the "-fanalyzer" option for spotting potential code issues. For GCC 10 this integrated static analyzer operating off GCC's GIMPLE was in good shape for catching various bugs while for the upcoming GCC 11 it is now much more capable...

Just last week I wrote about Itanium IA-64 support in Linux kernel being broken for a month during the Linux 5.11 kernel cycle. That was fixed but since then another regression came to light that had been affecting all IA-64 hardware since a patch was merged back in October. A fix for that latest regression has landed while in the process now marking the Itanium architecture as orphaned...

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...

A new Radeon power management feature with RDNA2 graphics processors being exposed by the open-source Linux driver is Duty Cycle Scaling in the name of power/thermal management with a focus on low-power hardware...

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...
