The GCC 12 compiler code-base has reached zero P1 regressions (the highest priority) and thus the GCC 12 compiler code has been branched from mainline, a release candidate is imminent, and if all goes well GCC 12.1.0 as the stable release could be out as soon as the end of next week...

Last week AMD quietly launched the Radeon RX 6400 series as the new low-end RDNA2 graphics. With Radeon RX 6400 there are finally low-profile, single-slot PCIe RDNA2 graphics cards whether they be for 2U servers, mini ITX builds, or other interesting use-cases. Up for testing today is an XFX Radeon RX 6400 4GB low-profile graphics card for Linux benchmarking.

While AMD long ago stopped actively contributing to the open-source R600 Gallium3D driver on Linux systems for OpenGL on Radeon HD 2000 "R600" through Radeon HD 6000 "Northern Islands" graphics cards, thanks to a few open-source community developers this Mesa driver code continues seeing improvements even with the Radeon HD 6000 series already being more than one decade old. The latest on the R600g front are various efforts improving the GPU compute support...

With last week's release of the much anticipated Ubuntu 22.04 LTS, Canonical announced they would begin providing a real-time kernel flavor too for this Long Term Support release though that RT kernel is initially in beta form. Today they outlined more information on their real-time kernel beta and how to actually go about trying it out...

LLVM 14.0.1 released just earlier this month while already LLVM 14.0.2 is out today.

While Intel launched the Arc A-Series Mobile Graphics at the end of Q1, so far at least in major US markets no laptops with these graphics are currently available. As such it's hard to assess the current Linux driver support level and with no clear communication from Intel on the matter. Intel has been working on their upstream DG2/Alchemist support for a while but it looks like with the Linux 5.19 kernel this summer is what will likely be their base version requirement for the DG2/Alchemist-based Intel GPUs...

Back in 2020 file-system driver provider Paragon Software announced they wanted to upstream their NTFS driver into the Linux kernel. This driver was previously a proprietary, commercial offering from the company but given the state of NTFS these days they wanted to upstream this driver with full read/write support and other features not found within the existing NTFS driver. Finally last year after going through many rounds of review, the new driver was merged into Linux 5.15. Sadly, less than one year later, concerns have been raised that the driver is already effectively orphaned and not being maintained...

It looks like Linux 5.19 will have all the base preparations in place for Arm Scalable Matrix Extension (SME) support...

Originally attempted with Linux 5.18 were patches so /dev/urandom and /dev/random would behave exactly the same. That was dropped though due to not enough randomness at boot for some platforms like Arm 32-bit, Motorola m68k, Microblaze, Xtensa, and others. But then the change went in to opportunistically initialize /dev/random as a best-effort approach where it at least works nicely on x86/x86_64. The good news is that original unification effort may be re-visited in the future now that the original blocker issue has been addressed...

Last week AMD began shipping the much anticipated Ryzen 7 5800X3D as their first 3D V-Cache consumer CPU and their claims to be "the world's fastest PC gaming processor" in being able to outperform even the Core i9 12900K / 12900KS for Windows gaming. We weren't seeded by AMD for this launch, leading us to anticipate that it's not too good for Linux gaming / not their target market. But after the great success I've had with AMD Milan-X performance on Linux, I was very eager to try out this consumer CPU with the 3D-stacked L3 cache and ended up purchasing a 5800X3D. Indeed the Ryzen 7 5800X3D turned out to be disappointing for Linux gaming performance but the 5800X3D was very interesting for a range of other technical workloads and making me very excited for future Ryzen CPUs with 3D V-Cache.

For two years there has been interest and unmerged patches for allowing Linux's plethora of firmware blobs to be Zstd-compressed for helping to save disk space. Finally it looks like for Linux 5.19 that optional Zstd firmware compression support will be merged...

While back in March Ubuntu 22.04 "Jammy Jellyfish" changed the default behavior for NVIDIA's driver to use Wayland inline with Intel and Radeon graphics having used the GNOME Wayland session rather than X.Org for the past few releases, this change was reverted at the last-minute. With a launch-day SRU, Ubuntu 22.04 LTS is defaulting to using the GNOME X.Org session rather than Wayland when running the proprietary NVIDIA driver...

With Mesa 22.1 having been branched and working its way towards release in early to mid May, it's a good time to deliver some fresh Linux gaming benchmarks on the latest GPU drivers. In this article are some reference benchmark results of various AMD Radeon graphics cards on Mesa 22.1-rc1 as of branching paired with Linux 5.17 and then benchmarked against NVIDIA's latest driver and various GeForce RTX GPUs.
