For a number of years Google has developed Fibers (not to be confused with Google Fiber, their fiber Internet service) as a user-space scheduling framework. While it hasn't been open-source, the few public papers and talks on Google Fibers has been quite interesting for great performance and a novel design. Finally though Google is working towards open-sourcing Fibers and hoping to get the necessary Linux kernel modifications upstreamed...

Intel's open-source graphics driver engineers have sent in their final feature pull request to DRM-Next of new material they are wanting incorporated into Linux 5.14...

Sent in last weekend to the Linux 5.13 kernel was the change so Linux x86/x86_64 will always reserve the first 1MB of RAM in order to avoid corruption issues with some BIOS and frame-buffers sometimes fiddling with that lowest portion of system memory. While the thought was reserving that first 1MB unconditionally was a bit onerous and that perhaps Windows has some way of determining how much low memory area to reserve, it turns out Windows has been employing this same behavior for years...

Often times when checking out thin clients and industrial PCs / IoT units from OnLogic and other industrial PC vendors, they tend to be Intel powered and within the forums the first question is often about any AMD equivalent... For those wondering about any new AMD-powered thin clients / mini-ITX systems within an aluminum chassis, OnLogic has introduced the TM800...

As part of the curiosity-driven benchmarks and areas of technical interest now that we've gotten some of our initial Intel Xeon Platinum 8380 "Ice Lake" benchmarks out of the way has been looking into the performance of Linux's P-State CPU frequency scaling driver on the 3rd Gen Xeon Scalable server. Benchmarked for the latesting testing was the power/efficiency out-of-the-box with P-State powersave as used by default with many Linux distributions against the P-State "performance" mode as well as putting P-State into passive mode to be able to via intel_cpufreq to try the Schedutil governor that relies on the kernel's scheduler utilization data for making frequency scaling decisions. Here is a number of power/performance governor benchmarks with the dual Xeon Platinum 8380 server in these varying kernel configurations.

Sadly there isn't much to report on at this time around improved open-source "Nouveau" driver support for the recent GeForce RTX 20 and RTX 30 series while even the GTX 900 and GTX 1000 series graphics processors are in poor shape for this unofficial driver. But when it comes to the aging GeForce 200 series, select models there are finally seeing OpenGL ES 3.1 supported by this open-source driver...

While Qt 6.1 released just one month ago, Qt 6.2 as of today is already into its feature freeze. This quicker than normal time to feature freeze comes due to this year's Qt releases being tightened up following the Qt 6.0 debut at the end of last year. Qt 6.2 will be the first Long Term Support (LTS) release of the Qt6 series...

The Linux x86/x86_64 kernel code already had logic in place for reserving portions of the first 1MB of RAM to avoid the BIOS or kernel potentially clobbering that space among other reasons while now Linux 5.13 is doing away with that "wankery" and will just unconditionally always reserve the first 1MB of RAM...

In addition to getting Intel's Alder Lake hybrid processors ready for the Linux kernel and other areas of the operating system stack, Intel's open-source engineers have continued their trend in recent weeks of upstreaming more Alder Lake work into Coreboot...

Robert McQueen, the President of the GNOME Foundation Board of Directors, wrote a post this week ultimately about the GNOME project's need to broaden its focus in order to attract more new users and ultimately to be able to raise funds from new organizations outside of their traditional reach. If they aren't able to find new funding sources, they may need to scale back in some of their efforts but still have a sufficient safety net...

For two years now we have seen various open-source patches around ENQCMD instructions for the code compilers and the Linux kernel. This Enqueue Stores support is part of Intel's Data Streaming Accelerator coming with Xeon Scalable "Sapphire Rapids". But even with Sapphire Rapids not launching until later this year, the already merged Linux kernel code is force-disabling the ENQCMD instructions support as the current kernel support is deemed "broken beyond repair" and will need to be reworked...

A few months ago you may recall word of Crocus as a new Mesa Gallium3D driver for supporting Intel Gen7 Haswell graphics and older back through the i965 class hardware. That Gallium3D driver for the aging class of Intel graphics is nearing mainline Mesa with the work-in-progress merge request now pending as of this week...

It's been a few releases since there has been much in the way of new additions to Wine-Staging worth talking about. This staging/experimental version of Wine has at some points carried 700+ patches over upstream Wine but with not many new patches introduced recently while the flow of patches from staging to upstream Wine continuing, at this point its down to "only" 571 patches. With today's Wine-Staging 6.10 there are also some new improvements incorporated into this build...

Recently we have been running a number of compiler benchmarks looking at the recently released LLVM Clang 12 and GCC 11 open-source code compilers. There is as healthy and competitive competition as ever between GCC and Clang with the mainline Linux kernel these days working well under Clang, more software projects shifting to Clang by default, and the performance being as tight as ever between GCC and Clang for compiled C/C++ code on x86_64 and AArch64. In today's article are benchmarks of Clang 12 vs. GCC 11 on the dual Intel Xeon Platinum 8380 Ice Lake server.
