Following the bump in April from Cloud-Hypervisor v0.14.x to v15, Cloud-Hypervisor 16.0 was released on Thursday for this Intel-led open-source hypervisor that is leveraging Rust and focused on cloud and security use-cases...

Earlier this year was talk of Linux finally removing its legacy IDE subsystem that has been deprecated for years in favor of just maintaining the still-supported libata code for IDE support. The libata path is much better supported and matured for nearly two decades, but one of the holdouts was some Motorola 68000 series hardware -- like early Macintosh computers -- not being supported outside of the legacy context. That is finally set to change with Linux 5.14 so in turn the legacy IDE code will likely be able to be removed soon...

Linus Torvalds is known primarily in the past for his colorful scripture on the Linux kernel mailing list while today he does have a passionate and important read on the LKML around vaccinations for COVID-19...

Back in March during the announcement of Intel Foundry Services it was mentioned that SiFive and Intel were working together to allow RISC-V chips to be fabbed within Intel's facilities. Additionally, Intel Capital previously invested in SiFive during prior funding rounds. Now it turns out Intel is reportedly positioning to potentially acquire SiFive...

Merged today into Mesa 21.2-devel is OpenGL ES 3.1 support being exposed for the Panfrost Gallium3D driver that provides open-source Arm Mali graphics...

Last month System76 launched their Launch Configurable Keyboard. They sent over this new open-source keyboard for some brief testing and I must say the build quality has been top notch and while this is their first keyboard they are bringing to market, with their US manufacturing expertise that began with their Thelio computer cases, it has carried forward with their Launch keyboard. This keyboard is beautifully crafted and among the most durable (and heaviest) keyboards I've used in the past two decades. It reminds me of the IBM Model M from a quality perspective but with its own unique advantages.

Along with Intel having wrapped up their graphics driver feature work for Linux 5.14, AMD sent in another pull request too with more feature code they have ready for their AMDGPU kernel driver in 5.14 and will likely be their last major pull for this cycle too...

For over a year Amazon engineers have been working on DAMON as a new means of monitoring data accesses under Linux. That patch series has yet to be mainlined but continues being worked on with the intention of getting it upstreamed when ready. More recently the engineers involved have been working on a DAMON-based page reclamation implementation for the Linux kernel in dealing proactively dealing with systems having high memory load...

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...

The latest work happening on AMD's Radeon Open eCosystem (ROCm) front is a new release of AOMP, their LLVM Clang downstream focused on carrying the latest patches around Radeon OpenMP offloading support...

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...

It looks like AMD's rising marketshare in the data center is paying off as AMD is hiring more Linux kernel engineers...

Announced at the end of last year was an experimental Wayland driver for Wine providing native Wayland support without relying on X11/XWayland. In the months since that yet-to-be-merged driver has continued supporting more functionality and with the latest update is much more viable...

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...

Queued up now into the EXT4 file-system's "dev" tree is the recent work on a journal checkpoint ioctl (EXT4_IOC_CHECKPOINT) and optional support for TRIM/discard or zero-out support on journal flushes. This is the work that came about in recent months in working to ensure the privacy of deleted file names from the system...

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...
