RenderDoc 1.11 is out as the newest feature release for this leading open-source graphics debugger supporting platforms from Linux to Windows to the Nintendo Switch to even Google's Stadia and supporting all major graphics APIs...

One area not talked about much for Intel's latest Tiger Lake processors are hardened CPU security mitigations against the various speculative execution vulnerabilities to date. What's peculiar about Tiger Lake though is now if disabling the configurable mitigations it can actually result in worse performance than the default mitigated state. At least that's what we are seeing so far with the Core i7 1165G7 on Ubuntu 20.10 Linux is the opposite of what we have been seeing on prior generations of hardware.

Intel's Linux graphics driver developers have submitted their final batch of feature changes targeting the Linux 5.11 kernel...

Qt 6.0 is releasing in December and The Qt Company is already drafting plans for the release cycles of Qt 6.1 and Qt 6.2 LTS next year...

In September Arm began adding Neoverse N2 support to the open-source compilers initially with GCC and now the support has been merged into LLVM Clang 12 as well...

FUSE is well known to longtime Linux users for allowing file-systems to be implemented in user-space for where a Linux kernel port isn't feasible for portability or licensing restrictions, among other factors. There is also CUSE for character devices in user-space. Now being based on FUSE, there is "MUSE" being worked on for MTD in user-space...

Just some quick, friendly holiday reminders...

As part of Lenovo offering Linux pre-loaded on more laptops and desktops, they have been working on upstream improvements themselves along with their partners at Red Hat and others. One of the latest Lenovo-contributed improvements to the kernel is palm sensor support for newer ThinkPad notebooks...

Systemd 247 is out today as the latest major version of this Linux init system. Like most systemd releases, systemd 247 is very heavy on new features...

PHP 8.0 is out today as expected as a major update to this widely-used programming language for server-side programming and other purposes...

Unigine 2 remains one of the most visually stunning game and simulation engines out there. That's even with still using OpenGL (or Direct3D 11 also on Windows) while their Vulkan renderer remains in the works. Unigine 2.13 is out this week as their latest iteration of this visually incredible engine with first-rate Linux support...

OpenZFS 2.0 is getting quite close to release but isn't over the finish line yet and this week brings the seventh release candidate...

While the Radeon RX 6800 series is now shipping that was developed under the Sienna Cichlid codename, there are other fishy codenames remaining and are seeing more work for the Linux 5.11 kernel that will officially open development in December and then likely reaching stable in February...

For those with some extra time around the US Thanksgiving holiday, the Arcan display server/environment is out with a new release. This is the interesting project that's powered in part by a game engine, offers X11 and Wayland compatibility, ported to BSDs, and more recently has been exploring VR and other desktop innovations...

The Godot Game Engine has been funding work on a GPU-based texture compressor to deal with the issue that importing textures to this leading open-source game engine can often be painfully slow...

Blender has been gaining a lot of ground this year with numerous prominent organizations now backing its development (just most recently, Facebook) and just at the end of summer they delivered Blender 2.90 while out today is Blender 2.91...

PHP 8.0 is scheduled for release tomorrow on the US Thanksgiving day. PHP 8.0 brings with it many new language features on top of the opt-in JIT compiler support. Here is a look at some of the PHP 8.0 changes along with a quick look at the near final performance of PHP 8.0 on an AMD EPYC Linux server...

Last week a new vulnerability was made public for IBM POWER9 processors resulting in a mitigation of the processor's L1 data cache needing to be flushed between privilege boundaries. Due to the possibility of local users being able to obtain data from the L1 cache improperly when this CVE is paired with other side channels, the Linux kernel for POWER9 hardware is flushing the L1d on entering the kernel and on user accesses. Here are some preliminary benchmarks looking at how this security change impacts the overall system performance.

Thanks to work by AMD and SUSE engineers, the Linux kernel could soon be seeing frequency invariance support for EPYC 7002 "Rome" processors for yielding greater performance and power efficiency...

While Metro Exodus can run on Linux right now via Steam Play, 4A Games is still working on a port of this popular game to Linux and Mac systems...
