Stemming from the recent news in Fedora 32 potentially LTO'ing packages by default for better performance and not yet having checked on the Link-Time Optimization performance of the in-development GCC 10, here is a fresh look at the possible performance gains from making use of link-time optimizations for generating faster binaries. This round of testing was done on the AMD Ryzen Threadripper 3960X and is complementary to the recent Profile Guided Optimization benchmarks.

AMD has issued their first update to the open-source Radeon GPU Profiler since the v1.6 update last July that introduced initial RDNA/Navi support...

When navigating the AMD.com driver downloads area the Radeon Software for Linux 19.30 driver is still referred to, which was released back on 5 November. That 19.30 driver series has been around for a while and we've been waiting for the 19.50 series driver to match their recent Windows driver update. It turns out there is a Radeon Software for Linux 19.50 driver that is public albeit not widely advertised...

Linux 5.5 as of this morning should have one less performance regression in tow if you are running on Debian/Ubuntu or otherwise having AppArmor enabled...

As you may recall a few days ago there was the information on the Linux kernel scheduler causing issues for Google Stadia game developers. The scheduler was to blame and in particular Linux's spinlocks. Linus Torvalds has now commented on the matter...

It's 2020 and GIMP remains one of the last holdouts for a major software application still relying upon the GTK2 tool-kit even with GTK4 potentially coming around the end of the calendar year. Fortunately, at least, the GIMP 2.99.x development releases on the path to the GTK3-based GIMP 3.0 should be starting up soon...

Arch Linux has been working the past several months on transitioning to Zstd-compressed packages in place of XZ compression for faster package installation. At the end of December that package compression scheme changed and the results are impressive...

The Liquorix kernel is the long-standing effort for providing a "better distro kernel" optimized for desktop/multimedia/gaming workloads. As it's been a while since last testing the Liquorix kernel spin of Linux, I recently carried out some tests of its Linux 5.4 based kernel compared to Ubuntu's generic mainline PPA images of Linux 5.4 as well as the low-latency kernel variety.

Last week I wrote about the AMD Secure Processor support for Linux 5.6 being queued as part of the cryptography subsystyem work with supporting the PSP / Secure Processor of Raven Ridge APUs. That AMD Secure Processor support is now rounded out with the Trusted Execution Environment (TEE) driver being queued for wiring into that subsystem...

Zink was one of the Mesa/Gallium3D innovations that saw mainline status in 2019 for offering OpenGL support atop Vulkan hardware drivers. While an interesting approach, so far only the dated OpenGL 2.1 support has been exposed but the Collabora-led effort is closing in on OpenGL 3.0 capabilities...

With Red Hat shifting their support to Wayland and expecting the X.Org Server to go into a hard maintenance mode quickly, in 2019 indeed it did...

Back in late 2018 when Linus Torvalds went on a sabbatical from kernel development to focus on his inter-personal skills, the kernel added a Code of Conduct. To date there hasn't been much transparency into the Code of Conduct committee that acts upon violations, but that is changing in 2020...

While complicated by New Year's festivities, Wine 5.0-RC4 was released today with just fifteen bug fixes for the week -- also a sign of the development cycle winding down for this annual Wine stable release...

For months there has been many different discussions over the Linux desktop's poor performance when under memory pressure / out-of-memory type situations. That has resulted in some upstream work so far like GNOME GLib's GMemoryMonitor as well as discussions by distribution vendors about what solutions they could enable today to help the low memory situations. Fedora 32 could begin shipping and using EarlyOOM by default to help in this area...

Hitting Mesa 20.0-devel a short time ago were a set of patches to the Radeon Gallium3D video code for fixing 10-bit HEVC video decode support...
