Two bits of Linux driver news to share today, one quite big for AMD/Intel and the other on the smaller side for NVIDIA.

Starting with NVIDIA, following on from the Vukan Beta driver update on the 15th they did a quick-fix and put another up with 440.58.02 yesterday. The only noted fix is "a regression which added syntax errors into the default application profiles configuration file" and that was specific to Linux.

As a reminder, NVIDIA's Vulkan Beta driver isn't something you need to use, it's essentially their staging area for advanced features and API updates before going into their main driver. Good for developers and for extra Linux testing in some cases.

On the other side for AMD/Intel we have the huge Mesa 20.0.0 release that was also announced yesterday. The announcement was short and to the point, reminding people to stick with Mesa 19.3.x if they want stable drivers until the 20.0.1 release is out to fix up any lingering issues. This is because it's a major new release bringing in support for new GPU models, performance improvements, OpenGL 4.6 compliance and more.

TemplarGRFor the first time on my AMD GPU i have full OpenGL(core+combatibility profile)/ES/Vulkan compatibility, up to the latest version.
Now waiting for OpenCL (for Blender). Or for something like Nvidia Optix but from AMD.

Well, AMD does provide ROCm for Open source OpenCL, and there is the binary OpenCL module from the closed source driver than you can you use alongside MESA. But i agree if they finally make Clover(the MESA OpenCL implementation) decent it would be really cool. I think now that MESA is complete they might get to work on it now.

My case is (was before i switched to Nvidia) Blender + Arch + Radeon HD 7850.
AFAIK ROCm doesn't support this GPU. And OpenCL form closed source driver crashes for me (bug was reported long time ago). Catalyst worked but with bugs too.

Yeah, ROCm works for Fury cards and later and needs PCI Express 3.0. Plus the binary OpenCL module does have a metric ton of bugs (for me Libreoffice crashes when enabling OpenCL). That is why MESA should attempt to complete Clover (Gallium Compute). It won't be much work, considering most gallium drivers support NIR and OpenGL 4.6 already. All they have to do is implement the missing API functionality for the state tracker and pass the conformance tests. It is sad that AMD stopped contributing to this project and Intel prefers to have a different OpenCL library altogether...

Does it work with ANY AMD GPU after Fury? Does it work with Blender? Does it work on Arch? If answer is yes then my next GPU will be AMD.

I don't use ROCm, but the binary OpenCL module from AMD drivers works on my gpu with Blender, on Arch. Now, granted, i haven't done any serious work with Blender, only tested that it is enabled, so take what i said with a grain of salt, you will have to ask heavy duty Blender users for that.

As for ROCm, i do know from what i have learned from others that indeed it does work for the GPUs after Fury. Perhaps the latest architecture, Navi, is lagging a little behind, not as mature as Polaris or Vega, but it is in their plans to support it. Just make sure you have PCI Express 3.0 or later and you are fine.
