In addition to the AOCC compiler for Zen CPUs, another LLVM/Clang downstream maintained by AMD is the AOMP compiler as where they host their various patches not yet merged around Radeon OpenMP offloading support. This week marked the release of AOMP 13.0-5 as their latest work on that front for the newest OpenMP GPU offloading capabilities...
AMD just lifted the embargo on the Radeon RX 6600 XT, its newest entry in their RDNA2 line-up and optimized for delivering a superior 1080p gaming performance against the NVIDIA GeForce RTX 3060 series. The RX 6600 XT isn't hitting retail availability until August and that is when we'll be able to publish benchmarks, but for now here is an overview of this new graphics card launching at the $379 price point.
Valve contractor Mike Blumenkrantz is known for his work on the Zink OpenGL-on-Vulkan implementation but recently has also been engaged in some of the Lavapipe software Vulkan driver work and related to that is the venerable LLVMpipe OpenGL Gallium3D driver. Needless to say, there's some interesting work happening...
Those having to deal with data stored on NTFS partitions from Linux have been eagerly awaiting the "NTFS3" kernel driver that Paragon Software has been working now for a year to upstream into the Linux kernel. No pull request has been sent in yet but the twenty-seventh spin of this driver was published today...
Following the recent benchmarks seeing how AMD's new AOCC 3.1 compiler has brought some performance improvements over the prior AOCC 3.0 release that introduced initial Zen 3 optimizations, here are some benchmarks looking at how that latest AMD Optimizing C/C++ Compiler performance compares to the upstream LLVM Clang 12 compiler for which it is based as well as against GCC 11 as the latest GNU compiler release that remains common to Linux systems.
While solidly into the "fixes" stage of Linux 5.14 kernel development, the x86 platform driver pull request this week -- which has already been merged to mainline -- does have some new additions worth mentioning...
RenderDoc continues maturing gracefully as the leading frame-capture based graphics debugging system for OpenGL / Direct3D / Vulkan across all major operating systems as well as some consoles...
Last month I wrote about a possible global counter for block/disk changes on Linux being discussed by Microsoft and systemd developers to better track changes via a system-wide monotonically increasing number as an alternative to the existing per-disk tracking. That functionality is now queued up as part of the block subsystem changes ahead of the Linux 5.15 merge window in a few weeks...
Intel's open-source "Iris" Gallium3D driver for providing modern OpenGL driver support on their graphics hardware from Broadwell through all current Gen12 / Xe Graphics era hardware has been in great shape for some time and works wonderfully. But Intel's not done furthering this Linux OpenGL driver and today they now have threaded shader compilation merged...
The work going on for over a year to optionally flush the L1 data cache on context switching is going to try again for the next kernel cycle as an opt-in feature for select tasks. This was the feature rejected last year by Linus Torvalds that went on to "beyond stupid" and other concerns about it when it was trying to be mainlined originally...
While the AMD Ryzen 9 5900HX performance is great on Linux once overcoming any laptop support quirks like with the ASUS ROG Strix G15 "AMD Advantage" laptop running into keyboard and WiFi issues on Linux depending upon the kernel version, how does the performance compare to Microsoft Windows 10? Here are some benchmarks of that ROG Strix G15 AMD laptop under Windows 10 as shipped by ASUS against Ubuntu 21.04 when upgraded to the Linux 5.13 stable kernel.
FreeRDP as a leading open-source implementation of the Remote Desktop Protocol is up to version 2.4 and exciting about this release is multi-threaded decoding support...

The open-source Mesa RADV driver for independent Radeon Vulkan driver support on Linux has been working towards supporting ray-tracing for months. Progress is being made with the latest being more test cases passes and even the Quake II RTX game rendering correctly, but the performance is far short of being satisfactory yet...
Following the formation of the Open 3D Foundation and their open-source IBM-led work around watering farms from the cloud, the Linux Foundation's newest effort is around trying to enhance firefighter safety with open-source...
The NVMe specification provides for an abrupt shutdown mode over the normal/safe shutdown command if needing to quickly get the NVMe solid-state storage ready for powering off as quickly as possible. Currently the Linux kernel isn't making use of the NVMe abrupt shutdown command but a proposal by Micron is looking to begin its usage...
Last week AMD released their AOCC 3.1 compiler that is their downstream of LLVM Clang/Flang and carrying various yet-to-be-upstreamed patches for benefiting their latest processors. While just a point release, curiosity got the best of me for firing up benchmarks of this latest AMD Optimizing C/C++ Compiler release.
There is the phenomenon on Linux where when double-buffered rendering and missing vblanks can lead to the GPU running at a lower frequency when instead the opposite should happen so it will try to not miss vblanks in the first place. In the past there's been talks of "boost" support in the GPU drivers or also workarounds from user-space like dynamic triple buffering, but sent out this week is a new proposal around DMA-Fence deadline awareness as another means of addressing this problem...
Going on for more than one year now is the effort for supporting KVM virtualization with the RISC-V architecture, which is very much important for RISC-V processors to be able to eventually take lift in the server space. The KVM RISC-V enablement work is now up to its nineteenth revision but not yet clear if it's ready for mainlining...
Google engineers and other parties are interested in being able to create swap spaces on Linux systems that would be reserved just for system suspend/hibernation purposes and not for generic swapping to disk...

One year after Haiku R1 Beta 2, the third beta of this inaugural release of the open-source Haiku operating system is now available for testing. Haiku remains the open-source OS project going on two decades for advancing as the spiritual successor to BeOS...
Following last week's big kernel in the form of Linux 5.14-rc2, rc3 is now available and it's much saner this week with fewer changes and those scattered changes being on the smaller side...
The BLAKE3 cryotpgraphic hash function that was announced last year and based on its predecessor BLAKE2 has now reached version 1.0 for its official/reference software implementation. BLAKE3 continues to be much faster than BLAKE2 while also being much faster than the likes of SHA-1/SHA--2/SHA-3 and even MD5 while being more secure...
When sticking to Wine recommendations of maintaining separate prefixes per-application, a lot of system files get duplicated for each game/application and in turn leading to significant bloat. With the current state of Wine it can mean hundreds of megabytes per prefix in duplicated files. But proposed reflink patches for Wine are aiming to cut down on this severe bloat...
This past week were the initial Linux benchmarks of the Ryzen 9 5900HX with the ASUS ROG Strix G15 laptop. Ubuntu was used as the default test platform as usual given its popularity and arguably the most relevant Linux distribution to use given that it's the most common Linux distribution at the moment for preloads on laptops by multiple vendors. In any case, as usual many users were quick to say "but Arch Linux!" as if it was going to make a dramatic difference in my findings. Well, here are some Ubuntu 21.04 versus Arch Linux benchmarks on that AMD Advantage laptop.
The latest Linux kernel feature proposed by Microsoft that is now working its way to the mainline kernel is IMA-based target measurements for the Device Mapper (DM) subsystem for enhanced security...
While Loongson has been known for their MIPS-based Loongson chips that are open-source friendly and have long been based on MIPS, with MIPS now being a dead-end, the Chinese company has begun producing chips using its own "LoongArch" ISA. The first Loongson 3A5000 series hardware was just announced and thanks to the company apparently using the Phoronix Test Suite and OpenBenchmarking.org we have some initial numbers...
