Mesa 19.2.5 was just released earlier this week but now v19.2.6 has already been released due to the previous point release breaking IBM POWER builds...

Coming up this weekend with the Linux 5.4 kernel is emulation/spoofing of the SGDT/SIDT/SMSW instructions around UMIP for allowing newer 64-bit Windows games to run on Wine and Steam Play (Proton). With newer CPUs like the AMD Ryzen 3000 series that support UMIP, these instructions are not allowed to run in user-space with Wine due to UMIP. So while the first stable kernel release is about to land with this support, some Wine-based emulation not contingent on the kernel patches is also in the works...

Linux for years has supported monitoring NVMe drive temperatures when installing the nvme user-space utility and run as root, etc. But now finally with Linux 5.5 the kernel is supporting NVMe drive temperature reporting through the hardware monitoring "HWMON" infrastructure alongside other hardware sensors...

For those wondering if it's worthwhile for performance recompiling your key Linux binaries with the microarchitecture instruction set extensions and tuning for Ice Lake, here are some GCC compiler benchmarks looking at that impact for the Core i7 1065G7 on the Dell XPS 7390.

Blender 2.81 is now available as the latest minor yet significant update to this open-source 3D modeling software following the major Blender 2.80 release earlier this year...

While releasing the game on time might be more of a challenge, Valve did deliver in announcing Half-Life: Alyx as scheduled as their new flagship virtual-reality game...

The Khronos Group has officially confirmed Intel's new "Iris" Gallium3D driver as being a conformant OpenGL 4.6 implementation...

PHP 7.4 is due to be released next week as the annual major iteration to PHP7. Like we have seen through the PHP7 releases, while new features continue to be tacked on for this popular web-based programming language the performance has continued evolving. Here are the latest benchmarks of PHP 5.6 through PHP 7.4 while also looking at the PHP 8.0-dev performance that is in development on Git master.

Thanks to work done by 9elements Cyber Security for an unnamed client, there is now working open-source Intel TXT support for Coreboot with the patches under review for upstream inclusion...

While the official NVIDIA Linux driver has worked well with DisplayPort Multi-Stream Transport (DP MST) setups for years now for driving large displays, audio hasn't worked under Linux for NVIDIA's driver in this combination. But with the upcoming Linux 5.5 cycle that will be addressed...

The long-awaited WireGuard secure VPN tunnel functionality looks like it will land with the Linux 5.6 kernel cycle happening in early 2020. Linux 5.5 is kicking off next week but the necessary crypto subsystem changes have yet to take place as well as a final sign-off on the new WireGuard code...

With the initial Navi 14 support to be found in the Linux 5.4 kernel releasing this weekend the GPU ASIC (along with Navi 12) have been marked as experimental and thus not enabled by default unless passing a special module parameter to the kernel. But now at the last minute this support has been deemed non-experimental for Navi 14...

Wednesday marked the v1.0.2878 update to Intel's "IGC" Graphics Compiler that is used by their graphics hardware compute stack...

Mesa 19.3 had been expected for release next week per their original release calendar, but as we are used to seeing for these quarterly feature releases, at least one if not more weekly release candidates tend to be needed for ironing out bugs. As such, Mesa 19.3.0 is now solidly looking like at least an early December release while Mesa 19.3-RC4 shipped on Wednesday...

The "Data Streaming Accelerator" (DSA) is a new block on future Intel CPUs that hasn't been talked about much publicly... Until now. Intel's open-source crew has begun detailing DSA for future Intel CPUs that will offer high-performance data movement and transformation operations. The Linux driver enablement has begun...

Mesa 19.2.5 is out today as the latest bi-weekly stable update to the current Mesa 19.2 series...

With Linux 5.4 due to be released this coming Sunday, 24 November, one of the big "winners" of this next kernel are AMD Radeon customers. Linux 5.4 brings support for new GPUs as well as better performance for existing graphics cards. Here are some fresh benchmarks of the performance wins as a result of the LRU bulk moves functionality.

Last week ago we provided a number of benchmarks looking at the performance impact from Intel's Jump Conditional Code (JCC) Erratum that required a CPU microcode update to mitigate but that comes with a performance hit. At least Intel has pending GNU Assembler patches to help offset that performance hit. In time for last week's articles I didn't have a chance to perform Skylake Xeon Scalable (1st Gen) benchmarks but now here are some metrics alongside Cascade Lake...

NVIDIA has released CUDA 10.2 for SuperComputing 19 week. CUDA 10.2 comes with some interesting changes, including to be the last release that will support Apple's macOS and the introduction of a standard C++ library for GPUs...

Intel's SVT-AV1 video encoder for AV1 is currently the fastest AV1 CPU-based encoder we have seen but it's looking like in due time Rav1e could be closing in on it if they continue with their current trajectory...
