After recently looking at the early LLVM Clang 12 compiler performance on the AMD Ryzen 9 5950X, in today's benchmarking is a look at how the GCC 11 compiler performance is looking in its near final state compared to GCC 10 under a variety of build CFLAGS/CXXFLAGS configurations on the AMD Zen 3 desktop.
Ampere Computing with their 80-core Ampere Altra processors and Mount Jade reference platform continue making progress on open-source firmware support for interested parties.
Linux 5.12 is bringing the initial infrastructure around ACPI Platform Profile support and with this kernel it's implemented for newer Lenovo ThinkPad and IdeaPad laptops. The support allow for altering the system's power/performance characteristics depending upon your desire for a speedy, quiet, or cool experience. With Linux 5.13 it looks like HP laptops with this capability will begin to see working Platform Profile support too.
Debian is the latest major Linux distribution deploying a Debuginfod web server so that ELF/DWARF/source-code information can be supplied via HTTP to clients on-demand when debugging.
An Oracle engineer has proposed introducing a new "-ftrivial-auto-var-init=" option for the GCC compiler that would allowing initializing automatic variables with either a pattern or zeroes in the name of security.

After a two year hiatus on the patches, VMware's Nadav Amit has gotten back to working on current TLB flushing support for the Linux kernel in yielding a small but measurable performance improvement.
In yesterday's Linux distribution benchmark comparison on a Ryzen 9 5900X, you may have noticed some of the Ubuntu 21.04 development benchmarks coming in slower than Ubuntu 20.10 but overall a tight race. That is something I've seen now on other systems too -- such as these results to pass along today from an Intel notebook with the latest Ubuntu 20.10 vs. 21.04 development tests.
Thanks to Google engineers the Linux 5.12 kernel is providing punctual support for eMMC inline encryption that is being ratified with a forthcoming specification update and already being found within some mobile hardware.
Firefox 86.0 is out today as the latest monthly update to this open-source web browser that continues to work on ramping up its security offerings.
The open-source Mesa Radeon Vulkan driver "RADV" has now enabled displayable DCC (Delta Color Compression) support that should yield some performance benefit while there still is more work to be completed.
The HID subsystem updates were sent in this morning for the ongoing Linux 5.12 merge window.
GNOME 40 beta is coming together with the GNOME Shell and Mutter components having seen new releases on Monday.
Libinput 1.17 is out as the newest version of this Wayland/X.Org input handling library for the Linux desktop.
Released yesterday was dav1d 0.8.2 as a fairly significant update to this AV1 CPU-based decoder. For those wondering what this update means for performance, here are some initial benchmarks.
The first release candidate of systemd 248 is now available with a number of improvements ranging from a new "system extensions images" concept to the out-of-memory daemon (OOMD) being declared stable.
One of many interesting and original open-source projects to be started in 2020 was ZLUDA, an open-spurce drop-in CUDA implementation for Intel graphics. ZLUDA - developed independent of Intel and NVIDIA - is built atop Intel's oneAPI Level Zero interface (hence the name, ZLUDA) and allows for unmodified CUDA applications to run on Intel UHD/Xe Graphics hardware with near-native performance. Well, that's the goal at least but with the initial ZLUDA release were a number of support limitations.
The changes within the remote direct memory access (RDMA) subsystem for Linux 5.12 are deemed "quite small" but there is one interesting addition courtesy of Intel.
Given the recent release of Arch Linux based EndeavourOS and a Phoronix Premium supporter recently pointing out SalientOS as another interesting Arch-based Linux distribution, here are benchmarks showing how these easy/quick to deploy Arch based operating systems with sane defaults compare to that of Ubuntu, Fedora Workstation, and Intel's own Clear Linux. This round of February 2021 Linux benchmarking was carried out on an AMD Ryzen 9 5900X desktop stemming from premium member feedback.
Microsoft engineers continue increasing their contributions to the Linux kernel where it makes business sense for them, such as in the case of securing the Azure cloud given that around 50% or more of the instances run Linux. With Linux 5.12 there are integrity subsystem improvements coming from Microsoft.
Sent in last week were some AMDGPU "fixes" for Linux 5.12. While there are some fixes as part of the series, there are some new (minor) features enabled.
Dav1d is already the most performant and leading AV1 software decoder we have seen while out today is v0.8.2 that should speed-up the video decode process even more on modern x86/x86_64 and ARM hardware.
Greg Kroah-Hartman sent in the staging/IIO updates for the Linux 5.12 kernel and this time around are lighter than normal but still with a few interesting items worth mentioning.
Following the recent major rewrite to KDE's KWin compositor code there are more exciting improvements likely to come for KWin in improving its Wayland compositor support.
The block subsystem and related storage changes were merged today for the in-development Linux 5.12 kernel.
Earlier this month at the virtual FOSDEM 2021 conference was an interesting presentation on how European developers are preparing for AMD-powered supercomputers and beginning to figure out the best approaches for converting existing NVIDIA CUDA GPU code to run on Radeon GPUs as well as whether writing new GPU-focused code with OpenMP device offload is worthwhile.
Oracle continues maintaining Solaris 11.4 with monthly stable release updates but there still is no public sign of anything past 11.4 for this operating system that was once exciting during the Sun Microsystems days. But with this week's 11.4 SRU30 release, at least there are many package updates.
There is a lot of new hardware enablement with the ARM platforms and DeviceTree additions for the Linux 5.12 kernel merge window.
Mesa's on-disk shader cache, which is used for speeding up game load times by avoiding the redundant recompiling of shaders on successive loads and also helping performance for software that compiles shaders on-the-fly, is seeing a big improvement with Mesa 21.1. Mesa 21.1-devel merged this weekend the new single file cache implementation.
While the first week of a new merge window is often one of the busiest times for Linus Torvalds in overseeing the Linux kernel, until last night there was no actual Linux 5.12 code being pushed into the Linux Git repository. Linus was offline most of the week due to winter storms preventing him from pushing to the Git repository and interacting much with the mailing list.
XFS maintainer Darrick Wong characterized the file-system driver changes for Linux 5.12 as "a lot going on this time, which seems about right for this drama-filled year."
With Fedora 34 aiming to use PipeWire by default for audio use-cases currently handled by PulseAudio and JACK, the Red Hat developers working on PipeWire remain very busy in addressing bugs and wiring up new functionality for this audio and video framework/server.
It's been nearly one year to the day since the release of Netrunner 20.01 as this desktop Linux distribution focused on providing a good KDE-based desktop environment and backed by Blue Systems. Today Netrunner 21.01 has been released as the latest step forward for this KDE desktop distribution built atop a Debian base.
With Valve's Portal 2 having added a Vulkan renderer by way of DXVK for converting Direct3D calls to Vulkan, here are some initial benchmarks with several different AMD Radeon graphics cards for seeing the performance of this nearly decade old game on Linux with the existing OpenGL rendering path compared to that of the new Vulkan rendering option.
When it comes to original, open-source computer games the 0 A.D. real-time strategy game is among the best. The game has been developed as open-source for more than a decade for this ancient warfare themed game. The prior 0 A.D. Alpha 23 release happened back in May 2018 while now it's finally been succeeded by 0 A.D. Alpha 24.
An exciting new capability with perf in Linux 5.12 is the ability to collect instruction latency metrics as part of the performance reports, but relies on hardware capabilities for now only found in next-generation Intel Xeon "Sapphire Rapids" processors.
The Mesa release train once again fell off the tracks for Mesa 21.0 but on Friday the fifth release candidate managed to ship.
The issue of having a beginner/easy-to-use focused desktop Linux distribution but not installing new security updates by default without user intervention is that for many users they fall behind in applying often important security fixes.
