mesa 20.2.0
Hi list, After a long wait, mesa 20.2.0 is now available. This is the first stable release of the series, but it's also been a very long time since the last release, and as such I'd like to reiterate that those looking for the most stable experience will likely want to wait for mesa 20.2.1. I'm back to the office and finally getting back in the swing of things after a long vacation, so expect more regular releases for the 20.2 series from here on out. shortlog ======== Alyssa Rosenzweig (1): pan/bit: Set d3d=true for CMP tests Andrey Vostrikov (1): egl/x11: Free memory allocated for reply structures on error Bas Nieuwenhuizen (7): radv: Fix threading issue with submission refcounts. radv: Avoid deadlock on bo_list. spirv: Deal with glslang not setting NonUniform on constructors. radeonsi: Work around Wasteland 2 bug. spirv: Deal with glslang bug not setting the decoration for stores. ac/surface: Fix depth import on GFX6-GFX8. st/mesa: Deal with empty textures/buffers in semaphore wait/signal.

Mesa 20.2 Released With RADV ACO By Default, Initial RDNA2 Graphics Support
Mesa 20.2 has managed to release just before the end of the the quarter. This Mesa Q3'2020 graphics driver update is coming out about one month behind schedule but the wait is worthwhile given many open-source OpenGL and Vulkan driver updates.
There is new GPU support, RADV is using the ACO shader compiler by default, much better LLVMpipe OpenGL support, new Vulkan extensions, and much more.

Open source graphics drivers get a boost with Mesa 20.2.0 out now
The latest and greatest in open source graphics drivers has released with Mesa 20.2.0, although you should wait on it if you're after a stable experience.
As always, the Mesa team suggest waiting on at least the first bug fix release with Mesa 20.2.1 which is usually out within a few weeks. Developer Dylan Baker who announced the new release mentioned to expect some more regular releases for the 20.2 series, as they're back from a long vacation.
What's new? Lots, as always. Support for new Vulkan extensions, added support for new GPUs including initial work done for AMD's upcoming RDNA 2 noted as "gfx10.3", expanded GLES 3.2 and OpenGL 4.5 support for LLVMpipe, lots of work on the Panfrost driver for Mali GPUs. You can find some release notes for Mesa 20.2.0 here.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
