It’s a great day: A big naval transport! It also means we can talk about Linux support and performance for the Radeon RX 6800 series and how well they work in Linux games. Here is an overview of the Linux driver status for these original RDNA 2 graphics cards and their performance with different open source driver stacks available.
Many Linux driver options available
In short, this is the best Linux driver support we have seen in the first of AMD’s next generation GPU. But even if it’s the best introductory support we’ve seen for the new generation of Radeon GPUs, there is still room for improvement – especially for Linux users who don’t feel comfortable putting together their own drivers, etc.. Support is already available in the large Linux kernel and mesa repositories, created this year under the code name Sienna Cichlid. Yes, today the RX 6800 and RX 6800 XT are both codenamed Sienna Cichlid.
Open source support is available, as well as a stack of driver packages for supported (business-oriented) Linux distributions. The boot performance can be further improved, especially for those who don’t feel comfortable updating the kernel to support the drivers, but in any case, all bits are now available in some form for those who want to boot the open source Radeon RX 6800 series.
Conditioned conductors
For those on Ubuntu 20.04 LTS for example, AMD would release the Radeon software update for Linux drivers serially today at 20:45. As usual, Radeon Software’s updated Linux driver package includes both the proprietary OpenGL/Volcano AMDGPU-PRO components and the open source Mesa and AMDVLK versions of AMDGPU-Open. If you don’t need the excitement and are using a supported Linux distribution, this is the easiest way to get help for Big Navi on Linux today. Install the new driver as usual with the Open/Pro components of your choice and you are ready to go.
Of course, not everyone is happy with the packaged driver because of the limited support (business management), or does not want to mock DKMS modules and other bits under Linux that could cause other problems, so there is online / open source support.
We’re gonna count!
A big advantage of using a complete driver: an OpenCL ROCm machine in operation! Benchmarks for OpenCL calculations on a packaged driver are covered in a separate article today. The OpenCL/Compute support for the Radeon RX 6800 series works and is better than the current RDNA 1 support. It’s great to see that in limited tests everything still works. It is likely that for the next version of ROCm 4.0 they will also have Big Navi support, no matter which driver is built in, but it is still great that this is happening.
