Back in March I benchmarked the Linux Kernel Runtime Guard (LKRG) as a means of achieving additional security safeguards for a ~5% performance hit. With LKRG 0.8 having been released a few days ago, here is a fresh look at the LKRG performance compared to the stock kernel on Ubuntu 20.04 LTS.

There is finally a new release out of The Dark Mod, the original total conversion mod for Doom 3 that transformed into its own standalone game powered by the open-source id Tech 4 engine. This remains the lone flagship example of the open-source id Tech 4 game engine in action by the community (besides the DHEWM3 / RBDOOM-3-BFG engine work) with ioDoom3 having never taken off like ioquake3...

Last month you may recall that the free software purists maintaining the GNU Linux-Libre kernel dropped the Intel "iGPU Leak" security fix for Ivybridge / Haswell as they considered the compiled shaders/kernels responsible for clearing those residual contexts to be binary blobs. A resolution is now pending for upstream...

With it already having been a few months since systemd 245 debuted with systemd-homed, the systemd developers have begun their release dance for what will be systemd 246...

Fedora stakeholders are debating the merits of potentially ending legacy BIOS support for the Linux distribution and to only support UEFI-based installations...

One of the security improvements being worked on in recent months by Intel's open-source team has been FGKASLR. But how is the performance overhead compared to just traditional KASLR? Here are benchmarks looking at the performance impact of FGKASLR on top, just KASLR, and then no address space layout randomization.

It's been quite an unfortunately wild year thus far with everything going on in the world, but at least within the open-source / Linux scope it's been an exciting time as ever. Here is a look at the top stories on Phoronix during the first half of this year...

Fedora for the past few releases doesn't show the GRUB boot-loader menu by default when only Fedora is installed on the system as there is little purpose for most users and it just interrupts the boot flow. But for those wanting to access the GRUB bootloader menu on reboot, they offer integration in GNOME to easily reboot into this menu. The other exception is the menu will be shown if the previous boot failed. This functionality has relied on downstream patches but now they are working towards a better upstream solution...

Zink is the generic OpenGL over Vulkan driver that has been in development as part of Mesa's Gallium3D code. It was just earlier this month that Zink achieved OpenGL 3.0 support and now it looks like OpenGL 3.1 will soon be flipped on...

Lua 5.4 shipped today as the newest version of the interpreter for this scripting programming language that is particularly popular for embedding within games and other applications...

Recently AMD posted UVD video decode support for GCN 1.0 with the AMDGPU driver, one of the long holdouts for letting the AMDGPU DRM driver approach feature parity with the longstanding Radeon DRM driver that is the default for GCN 1.0/1.1 era GPUs. That AMDGPU UVD GCN 1.0 decode support is going into the Linux 5.9 kernel later this summer after years ago Radeon driver developers largely dismissed the efforts of porting the UVD decode capability for these original GCN graphics cards over to AMDGPU...

The Linux Vendor Firmware Service (LVFS) for hosting firmware files to be consumed by Fwupd for firmware updating from Linux is on quite a streak...

Slated for Linux 5.9 is finally mainlining the FSGSBASE patches that have been floating around the kernel mailing list for years. Testing last week showed the tentative x86/fsgsbase patches helping Intel Xeon Linux performance but with AMD also supporting this instruction set extension going back to Bulldozer, how is it looking on the likes of AMD? Here are some benchmarks.

Over the weekend I began running some benchmarks of the Linux 5.8 development kernel on the Lenovo Flex 5 laptop with Ryzen 5 4500U. One of the standouts so far for from this Linux 5.8 testing compared to the stable 5.6/5.7 kernel series is better Radeon graphics performance with the Renoir laptop...

Following the announcement last week that future Apple computers will use in-house ARM-powered chips, some open-source projects have already begun prepping for the future ARM64-supported macOS 11...

Linux 5.6 brought initial USB4 support that primarily was starting things off by basing things off the existing Thunderbolt 3 support in the kernel for which this latest USB standard is based. For the Linux 5.9 kernel later this summer it's looking like there will be further work on getting Linux's USB4 support into good shape ahead of hardware appearing in the months ahead...

On top of an optimization to lower render times and reduce power usage and fixing window culling as another performance optimization, Canonical's Daniel van Vugt also came across another serious optimization for GNOME Shell's icon grid performance...

Following Linux's UEFI code getting cleaned up earlier this year in preparation for RISC-V support being added and then some early RISC-V UEFI patches, a more comprehensive set of patches for enabling UEFI support on RISC-V under Linux have been sent out...

Our recent benchmarks have shown WSL/WSL2 performance on the latest Windows 10 builds to generally be quite good compared to running bare metal Linux. But past the May 2020 Update and on the latest Insider Preview builds is the initial support for GPU acceleration in conjunction with updated Windows graphics drivers. The initial emphasis is on GPU compute with DirectML and for NVIDIA hardware CUDA support as well. Here are a couple CUDA benchmarks that ran gracefully under WSL2 albeit the performance leaves a lot to be desired...
