The second point release to Ubuntu 20.04 LTS is now officially released. Notable with Ubuntu 20.04.2 LTS is the new hardware enablement (HWE) stack that brings the Linux kernel, Mesa, and related components from Ubuntu 20.10, which means better hardware support that tends to be most notable around better open-source graphics support...

Security firm Corellium has been working on enabling the Apple M1 SoC under Linux and last month they posted initial Linux kernel patches for the Apple M1.

The AMD "frequency invariance" saga with Linux 5.11 continues... While there was a patch to address the previously noted performance regression caused by the introduction of frequency invariance and seen when using the Schedutil governor, a new CPUFreq-side patch series has been proposed instead -- both of which are addressing the performance issue with this new kernel for AMD Zen 2 / Zen 3 systems...

Fedora 34 is planning to switch to using Intel's modern Sound Open Firmware audio driver as it should be in good shape now and superior to the existing sound driver. This is ahead of Intel likely switching to the Intel SOF driver code path by default in the upstream kernel once this change has first been vetted by Fedora users...

Given the daily progress and changes made to the open-source AMDGPU Linux kernel driver and the Mesa drivers providing the open-source OpenGL (RadeonSI) and Vulkan (RADV) support, here is a look at how the Radeon RX 6800 series performance is currently for the latest Linux graphics driver code compared to the performance seen back on the November launch day for the Radeon RX 6800 and RX 6800 XT graphics cards.

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...

Linux 5.11-rc6 is out ahead of the stable release of Linux 5.11 coming in February...

Taiwins debuted last year as a compact Wayland compositor and focused on being modular with Wayland scripting support. Up to now Taiwins relied upon the WLROOTS effort born out of the Sway project for doing much of the Wayland heavy-lifting but the developer has now replaced it with its own Wayland support library...

Immediately following the CXL 2.0 specification being made public in November, Intel developers began posting Linux enablement patches for CXL 2.0 with an initial focus on type-3 memory device support. It's looking like that CXL 2.0 enablement work is now closer to being mainlined in the Linux kernel...

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...
