One of the Linux patch series that has been in the works for years in conjunction with Clang compiler side changes and already being responsible for exposing hundreds of kernel bugs is the KernelMemorySanitizer (KMSAN). Sent out today was the latest patch series working on the kernel infrastructure for catching uninitialized memory issues...

The Panfrost open-source, reverse-engineered Arm Mali driver stack so far has been focused on Midgard and Bifrost architectures but the newer Valhall graphics support is beginning to materialize. Since last year the developers involved have been working heavy on reverse engineering and bringing up Valhall. More of that Valhall driver support landed 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...

VMware has merged support for SVGAv3 into Mesa 22.2. SVGAv3 is the latest update to their virtual graphics device for allowing 3D guest virtual machine acceleration with VMware's virtualization products...

In order to fully support Direct3D Indirect Drawing for allowing more rendering tasks to be moved from the CPU to the GPU, the open-source RADV Radeon Vulkan driver is working on experimental code for effectively hosting "a driver on the GPU."..

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...
