Last week Valve introduced Vulkan rendering support for Left 4 Dead 2. The L4D2 Vulkan support is similar to that of Portal 2 where DXVK is being leveraged for translating the Direct3D calls to Vulkan rather than relying on their OpenGL translations. For those wondering what this means for L4D2 performance on Linux with modern GPUs, here are some benchmarks of Left 4 Dead 2 when testing the OpenGL and Vulkan rendering options.

Landing in mainline Mesa 21.2 development code last week was the "Crocus" Gallium3D driver for old Intel hardware spanning from the Intel 965 chipset days "Gen4" up through Crocus supporting Haswell "Gen7" graphics. The i965 to Haswell span has been the focus since the official Intel "Iris" Gallium3D driver already in Mesa supports the Broadwell "Gen8" up through all current Intel UHD/Xe Graphics. But now Crocus with the latest Mesa code has added Gen8 support...

Merged this past week was Crocus as the new open-source Intel Gallium3D driver developed by the community and used for Gen4/i965 through Gen7/Haswell generations of Intel graphics. This week I ran some Crocus benchmarks on Intel Haswell comparing against the existing i965 classic Mesa DRI driver while in this article are some comparison driver benchmarks using Intel Sandy Bridge graphics for those still running those once popular processors.

Published all the way back in September 2019 was a Linux driver for supporting the Pass-Through DMA controller for EPYC processors. The PTDMA hardware allows for high bandwidth memory-to-memory and I/O copy operations. Now mid-way through 2021 that AMD PTDMA Linux driver remains in the works and is up to its tenth driver revision while waiting to see if it's now ready for mainline or further changes are still deemed necessary...

Back in April the out-of-tree Reiser4 file-system was updated for Linux 5.12 compatibility while now with Linux 5.13 being right around the corner, Edward Shishkin has updated the experimental Reiser5 file-system code for v5.12 compatibility...

Earlier this month Linux 5.13 disabled Intel's ENQCMD functionality for upcoming Xeon "Sapphire Rapids" processors as the kernel software code around it was deemed "broken beyond repair". More of the recent Intel-submitted patches around reworking kernel code in preparation for upcoming CPU features has been found to be rather hairy after already being mainlined and thus another batch of urgent x86 fixes were sent in this morning...

While vendors are increasingly just focused on Vulkan (and Direct3D under Windows), there still is plenty of OpenGL software out there especially in the workstation space where software vendors are slow to adapt. Well known RadeonSI OpenGL developer Marek Olšák of AMD landed another performance optimization this week that should benefit the likes of SPECviewperf...

Mesa's Zink is well known for working to provide a generic OpenGL implementation over the Vulkan API that can be used across hardware/drivers. While still focused on OpenGL-over-Vulkan, with some pending patches it turns out Zink can support Gallium3D Nine for ultimately allowing Direct3D 9 atop this layer...

A few days ago I wrote about GravityMark as a new cross-API GPU benchmark from a former Unigine developer. Being curious about the Linux GPU driver performance for this benchmark that is focused on delivering maximum GPU acceleration support, I ran some benchmarks on the latest NVIDIA GeForce and AMD Radeon graphics cards with this benchmark for OpenGL and Vulkan.

Back in March NVIDIA announced they would be supporting the GeForce RTX 30 series with Resizable BAR support via a video BIOS update for supported systems. Recently I've been looking at the performance of a GeForce RTX 3080 once flashing the graphics card under Linux with Resizable BAR support and the performance is quite compelling for Vulkan-based games where this functionality is working.

While Red Hat Enterprise Linux 9 is dropping support for older x86_64 CPUs by raising the baseline requirement to "x86_64-v2" that roughly correlates to Intel Nehalem era processors and newer, so far Fedora has not changed its default. There was a proposal shot down last year for raising the x86_64 microarchitecture feature level while now that discussion has been restarted or alternatively making use of Glibc's HWCAPS facility for allowing run-time detection and loading of optimized libraries...
