Longtime GCC developer Honza Hubička of SUSE has posted a lengthy and quite interesting blog post concerning some of the optimization work that went into the now-released GCC 9 compiler. It turns out some of the GCC 9 optimization work was motivated by the Firefox developers and their desire to switch to LLVM Clang in the name of performance. Separately, openSUSE Tumbleweed has been looking at using link-time optimizations (LTO) by default for their packages and that has also motivated developers and help ensured the LTO support was in good shape for this annual compiler release...

Aspeed BMCs have seen a lot of mainline Linux kernel driver activity from a recent Aspeed video engine driver to an AST2500 SoC DRM driver queued for Linux 5.2 and now also joining that is the Aspeed P2A CTRL driver...

The Radeon (and Intel) graphics driver support on DragonFlyBSD has improved a lot compared to where it was at many years ago, but it remains a perpetual catch-up game with the porting of this driver code from Linux to their BSD kernel...

It looks like Intel's open-source Linux graphics driver support is now officially ready to roll for the "Gen 11" graphics to be found with Icelake, Elkhart Lake, and whatever other Gen11 graphics parts may end up coming. The latest open-source OpenGL/Vulkan driver code now marks Gen 11 as being feature-complete...

With today's release of the GCC 9 code compiler among the many features offered in this annual update to the GNU Compiler Collection is the initial "cascadelake" target/tuning support that enables AVX-512 VNNI tuning by default as the most notable change over the former "skylake-avx512" GCC target. Anyhow, for those wondering how the GCC 9 performance differs compared to last year's GCC 8 compiler release, here are some preliminary benchmarks...

Sway 1.0 was released nearly two months ago as the i3-inspired Wayland compositor while now on approach is Sway 1.1 as the newest feature release...

While we haven't yet spotted any of the other AMD Radeon "Navi" next-generation GPU support in the other software components making up AMD's open-source Linux graphics driver stack, there continues to be a lot of work happening on the AMDGPU LLVM shader compiler back-end within the mainline LLVM code-base. In fact, there's been over eleven thousand lines of new code so far pertaining to Navi/GFX10...

GNOME's Mutter compositor has seen a new, integrated clipboard manager for the in-development GNOME 3.34 cycle...

Darling is the open-source project we first covered back in 2012 that aimed to be able to run macOS software (binaries) on Linux. It's what Wine is to running Windows programs on Linux but rather to be able to handle Apple/Mac software. While we haven't heard much from the project recently, they still are pursuing their goal...

Should you be looking to control a vibrator over GPIO (general-purpose input/output), that capability is coming to the Linux 5.2 kernel thanks to a new driver...

One of the early features merged back in February for Mesa 19.1 was the new Vulkan Overlay layer to expose various performance metrics akin to the Gallium3D "HUD" also living within Mesa. Ahead of the Mesa 19.1 feature freeze, some more capabilities are now added to this Vulkan overlay/HUD...

Following the recent Chrome 74 web browser update, Google has now promoted Chrome 75 to its beta channel...

With the Linux 5.1 kernel release expected this weekend, it's too late to see any real features added to the prominent drivers in DRM-Next for the now imminent 5.2 merge window, but some fixes and FreeSync improvements are deemed ready for this next kernel cycle...

While Hitman was ported to Linux by Feral Interactive, Hitman 2 that was released back in November of 2018 hasn't seen a native Linux port. However, in recent months Hitman 2 has been running under DXVK+Proton with Steam Play for allowing this stealth video game to run nicely under Linux. More recently the latest Proton updates have worked around an issue that previously prevented our benchmarking of this game, so in this article is a look at the Hitman 2 Linux gaming performance with different AMD Radeon and NVIDIA GeForce graphics cards.

While Clear Linux has been outperforming other Linux distributions the past several years, it's a never ending job for them of continuing to lead the way in squeezing more performance out of x86_64 hardware on Linux. During the month of April, some more performance improvements were achieved though also a few regressions appeared to have slipped into their builds...

After seven years of development and more than forty-thousand commits, GNU Guix 1.0 has been released. Guix as a refresher is the transactional package manager that can be used atop other Linux distributions while the Guix System Distribution also serves as its own GNU/Linux flavor...

While Ubuntu is not currently using Wayland by default with its GNOME Shell desktop and it doesn't look like they will try again until Ubuntu 20.10, the option is still available and they continue working in the direction of a Wayland Linux desktop future. One of their interesting "upstream" contributions in this area is with the Wayland Conformance Suite...

Adding to the many changes for Linux 5.2 is Arm's new Komeda DRM/KMS driver being extended to support the Mali D71...

Version 0.3 of the "dav1d" AV1 video decoder was released on Tuesday and it delivers faster performance...

Yesterday we began with our preliminary performance benchmarks of Fedora 30. From those results Intel Core i9 and AMD Threadripper systems and what we're seeing on other systems in the labs, Fedora 30 indeed is coming out generally slightly faster than Fedora 29 when looking at the performance overall. In some cases the performance is much better thanks to GCC 9 and other upgrades, but overall it's a small, modest performance improvement. While that's better than seeing Fedora 30 running slower than its predecessor, there still is more potential to squeeze out of the system.

Well, here's a surprise... EA (yes, Electronic Arts) has joined The Khronos Group as a contributing member...
