On this last day of the Linux 6.3 kernel merge window, Linus Torvalds merged the patch dropping support for Intel (ICC) compiler support. Specifically this is Intel's long-standing ICC compiler now known as the "Intel C++ Compiler Classic" prior to its transition to being LLVM/Clang-based with the modern Intel DPC++ compiler...

This past week saw the first two consumer PCIe 5.0 NVMe solid-state drives released to retail: the Gigabyte AORUS Gen5 10000 and the Inland TD510. I've been testing the Inland TD510 2TB Gen 5 NVMe SSD the past few days. While in simple I/O testing it can hit speeds almost up to 10,000 MB/s reads and writes, for more complex workloads it quickly dropped against popular PCIe Gen 4.0 NVMe SSD options. In my testing thus far of this first consumer Gen5 NVMe SSD it's left me far from impressed.

Ahead of the Linux 6.3-rc1 release later today, a set of "x86/urgent" patches were sent out Sunday morning that include the change to allow Single Threaded Indirect Branch Predictors (STIBP) to be used in the presence of legacy Indirect Branch Restricted Speculation (IBRS) for security reasons...

Merged last cycle was a big Zstd update for Linux 6.2 that took the kernel's Zstandard compression/decompression implementation to match that of upstream v1.5 after being stuck in the v1.4 series for more than a year. Following that, Zstd 1.5.4 was released last month. The hope was Zstd 1.5.4 would quickly follow into the mainline kernel while that is now delayed to Linux 6.4 and for the 6.3 kernel cycle seeing just a few fixes...

A set of patches sent out this morning lay out the initial foundation for RISC-V auto-vectorization support within the GNU Compiler Collection (GCC)...

After earlier this week providing the initial Linux benchmarks of the AMD Ryzen 9 7950X3D across many Linux gaming tests as well as nearly 400 other tests, in today's article I am looking at the AMD Ryzen 9 7900X3D as the 12-core / 24-thread processor with the hefty 128MB L3 cache on this Zen 4 desktop processor. Due to having less time with the 7900X3D thus far, today's article is just getting things started in looking at the Linux gaming performance -- both native Linux games as well as many Windows games running on Linux thanks to Valve's wonderful Steam Play (Proton + DXVK / VKD3D-Proton) software.

Posted today was the "v1" patch series implementing threaded/atomic console infrastructure for printk. This is one of the last steps needed before the real-time (PREEMPT_RT) support can be finally mainlined into the Linux kernel...

For those doing large Linux kernel builds such as with the "allyesconfig" build option for including as many of the available drivers as possible into the assembled Linux kernel image, objtool improvements ready to go with Linux 6.3 should cut down on the RAM usage and also speed-up the kernel build time. These improvements were motivated by Linux kernel developers beginning to run out of memory when trying to carry out the "allyesconfig" kernel builds on desktops with 32GB of RAM...

Going back to 2016 Intel began work on the SoundWire support for Linux, the MIPI standard started in 2014 to help consolidate audio interfaces between PC and mobile hardware.

Following a three month lull, last week Intel got back to releasing Compute-Runtime and IGC compiler updates. They have been working to shift to a monthly release cadence while during this transition period they needed extra time as it also rolled out some compiler/runtime interface changes. Now back into their swing of things, for kicking off the new month they have the Compute Runtime 22.53.25242.13 release...

A few months back the generic xf86-video-modesetting X.Org driver added TearFree page-flipping support. The option eliminates screen tearing without the use of a compositor and was seen as a win by many for this generic DDX driver that works atop the modern DRM/KMS kernel drivers. But a rather annoying issue was discovered that could lead to audio/video synchronization problems was uncovered and is now fixed in the latest driver code...
