Following the recent Zen 4 tuning patches that were merged to GCC 13 (Git) just ahead of Christmas, today an AMD patch adding the Zen 4 automatons have been merged ahead of this next open-source compiler release...

After enjoying a two month holiday, Valve-funded Mike Blumenkrantz is back to working on Mesa's Zink code that implements OpenGL (and via Clover even OpenCL) atop the Vulkan API. Zink has shown it can be quite competitive in its OpenGL performance atop Vulkan compared to dedicated OpenGL drivers and in 2023 should be maturing into even better shape...

Those paying close attention to the Linux kernel development may have noticed a small change to how a key Linux developer is marking his kernel patches...

Sent out last year as "request for comments" were two rounds of patches by Google engineer James Houghton for introducing the concept of HugeTLB High Granularity Mapping (HGM) to the Linux kernel. In kicking off the new year, the set of 46 patches in their post-RFC state have been mailed out for review...

Tonight during Lisa Su's keynote for CES 2023, a number of exciting AMD announcements were made...

While not even midway through the Linux 6.2 cycle yet, the hardware monitoring "HWMON" sensor driver feature changes queuing in the "hwmon-next" branch is seeing more hardware support readied for Linux 6.3...

Red Hat has been among the key Linux stakeholders working for years toward the ultimate goal of ensuring the Linux desktop will have suitable High Dynamic Range (HDR) support in place. They are working to organize a hackfest this year to further the progress being made on HDR application support on the GNOME desktop as well as associated open-source graphics driver infrastructure...

Lighttpd 1.4.68 was released on Tuesday as the newest version of this lightweight, high performance open-source web server...

In addition to Fedora 38 now allowing "no-omit-frame-pointer" to enhance profiling/debugging with possible performance costs, this next Fedora Linux release is also planning to use "_FORTIFY_SOURCE=3" compiler defenses to further bolster security...

Over the holidays some fun benchmarking was to be had with the dual AMD EPYC 9654 "Genoa" processors providing a combined 192 cores / 384 threads and seeing how various modern Linux distributions were competing for this flagship 4th Gen EPYC server configuration. Up on the testing block was AlmaLinux 9.1, CentOS Stream 9, Clear Linux 37930, Debian 12 Testing, Fedora Server 37, Ubuntu 22.04.1 LTS, Ubuntu 22.10, and Ubuntu 23.04 daily.

Samuel Pitoiset of Valve's Linux graphics team has landed a few patches into Mesa 23.0 for further reducing the CPU overhead of the Vulkan driver's draw path...

Since GCC 11 there has been support for AMX and the upcoming Sapphire Rapids CPU features, which has been further improved in the open-source compiler over the past two years. GCC 13 meanwhile as the next GNU Compiler Collection release is bringing Meteor Lake and Sierra Forest, Grand Ridge, and Granite Rapids. Basic enablement of Intel's Emerald Rapids meanwhile was merged yesterday for GCC 13 too...

Microsoft released CBL-Mariner 2.0.20221222 on Tuesday as their first update of 2023 for their in-house Linux distribution that is used for a variety of purposes within the company from Azure to other behind-the-scenes Linux OS use...

GNOME's Mutter now allows disabling XWayland support at build-time if so desired. This is part of the broader GNOME effort for making X11 support optional and ultimately allowing for a modern Wayland-only environment if so desired and without carrying legacy X11 cruft...

While back in 2018 when the C-SKY architecture was merged to the Linux kernel it was talked about possibly being the last new CPU arch/port to be mainlined given the growing success of RISC-V even back then, it looks like that upstream kernel developer belief might not hold true. France-based Kalray that focuses on high-performance, data-centric computing from cloud to edge posted their initial Linux kernel patches today for their "KVX" kernel port to get the kernel running on their MPPA3-80 "Coolidge" DPU SoC with the KV3-1 CPU architecture...

The past several months saw much discussion over a proposal to add "-fno-omit-frame-pointer" as a default compiler flag to Fedora Linux that would improve profiling/debugging but with possible performance implications that can vary based on the application/workload. While just over one month ago FESCo rejected that change, they re-voted today and decided after all to allow this change to happen but to ensure that packages can easily opt-out if they find performance regressions. By Fedora 40 they will also re-visit the matter to determine if the benefits and performance costs are justified...

DragonFlyBSD 6.4 is now available as the newest version of this open-source BSD operating system forked long ago from FreeBSD...

It's been one year and a few days since BusyBox 1.35 was released while today it's been succeeded by BusyBox 1.36 for this software package that is common to embedded Linux environments with the lone executable providing a plethora of commands and functionality...
