Mesa Merge Pending For Vulkan Ray-Tracing On Older AMD GPUs

Merged yesterday for Mesa 21.3 was open-source Vulkan ray-tracing for AMD RDNA2 / RX 6000 series GPUs with the RADV driver. Opened today now is a merge request that would provide Vulkan ray-tracing with RADV to pre-RDNA2 GPUs on this driver going back to the likes of Polaris, granted the performance is another story.

Mesa 21.2.2 Released "Late & Very Large"

Mesa point releases generally come every two weeks but for the past month have fallen off the wagon. Mesa 21.2.1 came in mid-August and on Tuesday was finally succeeded by Mesa 21.2.2 as a "late and very large" update.

Google Is Successfully Using The Open-Source Qualcomm GL/VLK Drivers On Chromebooks

It's been known that Google has been using the open-source "MSM" DRM/KMS driver on Qualcomm-powered devices that originally started out as a reverse-engineered driver project separate from the company. Now it's also been confirmed how Google is successfully using the open-source Mesa Freedreno OpenGL and TURNIP Vulkan drivers on Qualcomm-powered Chromebooks too.

OpenGL Drivers In 2021 Still Sadly Benefit From Faking Their Driver Name / GPU

Years ago particularly when the open-source Linux GPU drivers were in their infancy it was known in some cases having to fake/spoof the GPU driver name or model in order to workaround artificial bugs / problematic code paths targeted to a particular OpenGL driver or even to achieve greater performance. With a new Mesa merge request called "Unleash the dragon!", this is still very much a problem in 2021 even now in the Android space.

Mesa 21.2 Lands NVIDIA's Code For Handling Alternate GBM Backends

Earlier this year was the proposed NVIDIA code from NVIDIA for allowing Mesa's GBM to support alternative back-ends. This support is notable given that most Wayland compositors are catering to using Mesa's Generic Buffer Manager (GBM) rather than EGLStreams or other options for buffer management. That support code has now been merged into Mesa 21.2.
