Even before the Linux 5.11 kernel was released on Sunday, Kernel-based Virtual Machine (KVM) maintainer Paolo Bonzini already had submitted early the initial batch of virtualization changes for Linux 5.12. There are some interesting changes on the KVM front for Linux 5.12...

It's approaching one year since the proposal of FUTEX2 for addressing shortcomings of the existing FUTEX system call and allowing the semantics to better match that of the Windows behavior, which is of use when running Windows games on Linux via Steam Play's Wine/Proton. In the end the FUTEX2 system call can lead to lower CPU utilization and in turn allowing for greater Linux gaming performance...

Building off yesterday's release of the Linux 5.11 kernel, the GNU folks have put out their "GNU Linux-libre 5.11-gnu" kernel that removes support for loading closed-source kernel modules, stripping out drivers/functionality that are dependent upon closed-source microcode/firmware, and other sanitization work in the name of maintaining a fully free software system...

Linux 5.11 should be released today as stable but we'll see if 5.11-rc8 is decided instead given there has been an uptick in last minute changes for this kernel. This will mean either the Linux 5.12 merge window is kicking off at the end of today or could be pushed back by one week, but in whatever case there are many changes that have been queuing up for this next kernel version window...

It's been eighteen years since the game Wolfenstein: Enemy Territory was released while thanks to the it becoming open-source along with the id Tech 3 engine, it's still being advanced by the open-source community in 2021...

Going back to last year there has been work by AMD engineers on an experimental FreeSync video mode optimization to avoid screen blanking around full-screen video playback. Basically avoiding an entire mode-set when changing the timing mode during video playback to bypass any screen flickering/blanking. That work has now been updated to its sixth spin while it's being viewed as a temporary measure until a better solution can be devised...

One year after OpenMandriva Lx 4.1 released, OpenMandriva Lx 4.2 is now available. Continuing to make OpenMandriva Lx rather unique among Linux distributions is its use of the LLVM Clang compiler by default rather than GCC. Another unique "selling point" of OpenMandriva is its AMD Zen optimized version where the entire package set is rebuilt with Zen optimizations...

Now with the CPUFreq fix landing this week in Linux Git, the mainline Linux 5.11 kernel in its near final state is looking in very good shape for AMD Zen 2/3 hardware from Ryzen laptops and desktops through EPYC servers. The Linux 5.11 development kernel was regressed for the better part of the past two months but now that the frequency invariance regression is addressed, not only is the regression gone but generally is performing much better compared to prior kernel versions.

Linux 5.11 stable is expected to be released on Sunday barring any second thoughts by Linus Torvalds that could lead to an eighth weekly release candidate that would in turn push the official release back by one week. In any case, Linux 5.11 will be formally out soon and it's an exciting one on the feature front...

With Linux 5.11 there is open-source Nouveau KMS support for Ampere GPUs -- just kernel mode-setting without any form of 3D acceleration. The actual hardware acceleration requires more work and also NVIDIA to release the necessary signed firmware binaries. With Linux 5.12 there still is no 3D acceleration but a big set of patches was merged as a step in that direction...

The newest OSPray Studio is now available...

It was just yesterday we were talking about Zink achieving OpenGL 4.3 support and wondering if OpenGL 4.4 or potentially even 4.5 could be buttoned up in time for Mesa 21.1... Well, as of a few minutes ago Zink now is advertising OpenGL 4.5 support for this graphics API layer built atop Vulkan...

With this spring marking two years already since Intel introduced the 2nd Gen Xeon Scalable "Cascade Lake" processors plus with Ice Lake Xeon processors being on the horizon, here is a look at how the flagship Xeon Platinum 8280 2P performance has evolved atop open-source Linux during that duration. The benchmarks today are looking at the performance of Ubuntu 19.04 for that of roughly the shape the Linux performance/optimizations were at launch and then the performance today if moving to the in-development Ubuntu 21.04 and also shifting to the latest Linux 5.11 kernel and GCC 11 code compiler.

The official release of FreeBSD 13.0 is coming up in March, while already from our preliminary tests of the newly minted FreeBSD 13.0 BETA1, the benchmark results are extremely tantalizing compared to FreeBSD 12.2... Ultimately the performance should be much more competitive now compared to Linux (at least on Intel x86_64) and other operating systems with the big FreeBSD 13 release.

While GRUB 2.06 was aiming for release in 2020, having to deal with the BootHole security issue among other challenges last year ended up delaying that release.
