Following the announcement this week that AMD is dropping pre-Polaris GPU support (or pre-Raven Ridge support for APUs) from their mainline Radeon Software driver on Windows, the AMDVLK open-source Vulkan driver has also now similarly discontinued that older GPU support...
Since Crocus was merged into mainline Mesa last week we have been looking at benchmarks of this new open-source Intel Gallium3D driver designed exclusively for older Intel graphics hardware (i965 Gen4 through Haswell Gen7, plus Cherrvyiew and experimental Gen8 Broadwell) compared to the existing open-source i965 classic driver. Prior articles have looked at the quite good performance with Haswell while Sandy Bridge is in somewhat rough shape. Today's testing is going in the middle and looking at the Crocus vs. i965 OpenGL driver performance for Ivy Bridge with the once great Core i7 3770K.

It's been three months since AMD published a security whitepaper outlining the possibility of a side channel attack with PSF. The Predictive Store Forwarding functionality is new to AMD Zen 3 (Ryzen 5000 / EPYC 7003 series) processors and as part of their security analysis they are allowing users the ability to opt-out of using this feature in the name of greater security but the feature still hasn't been picked up for the mainline Linux kernel...
While Valve has been working on Vulkan-based rendering for Source Engine games by making use of DXVK for translating the game engine's native Direct3D calls to the Vulkan API, with some yet-to-be-merged Mesa patches around Gallium Nine there is much better performance to see with Gallium Nine at least for the RadeonSI driver...

The Qt Company has announced the debut of Qt 6.2 Alpha as it prepares for its September release with many more modules finally making the transition from Qt5 to Qt6...
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...
Even though Vulkan ray-tracing support on Intel graphics hardware isn't coming until Xe HPG avaiability, Intel's Linux graphics driver developers have been preparing since last year. In preparation for the Xe HPG launch, Intel's open-source talent have for many months already been preparing the Vulkan ray-tracing functionality wither another batch of code being merged today...
While in the past we have seen Intel CPU microcode updates lead to measurable performance differences on multiple occasions, this month's CPU microcode update doesn't end up being all that concerning for real-world performance...

AMD today released FidelityFX Super Resolution that was announced earlier this month at Computex. Today it's Windows-only with no Linux support being introduced. FidelityFX Super Resolution is open-source but the code drop will not be until next month...
For those wondering how well the likes of FreeBSD 13.0 and DragonFlyBSD 6.0 performance on AMD's EPYC 7003 "Milan" processors launched earlier this year, here are some initial benchmarks of those BSDs alongside a few Linux distributions. With recently having a Tyan 1U server in the lab with EPYC 7543 32-core processor, I've been running a number of BSD benchmarks on it given these recent BSD releases have been running well on this 1P server.
AMD has shifted all their graphics processors and APUs prior to Polaris / GCN 1.4 to being legacy and will not be supported by their new Radeon Software Adrenalin releases...
The Haiku open-source operating system inspired by BeOS has been in development since 2001. It took until September 2018 for the Haiku R1 Beta and then last summer was succeeded by Haiku R1 Beta 2. Now a year later the third beta for this inaugural release is now approaching...

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...
