Updated Radeon Software 18.50 Linux Driver Tacks On Radeon VII Support


RADEON --

For those uncomfortable in building your own Linux kernel and Mesa in order to attain Radeon VII support (or don’t want to leverage third-party package repositories), there is a new Radeon Software for Linux driver release now available with Radeon VII support.

Today’s Radeon Software driver for Radeon VII on Linux is the same release stream as what shipped back in December: 18.50.

Besides adding support for second-generation Vega / Radeon VII, the only other change listed in the public release notes is the RHEL / CentOS 7.6 support, which was part of the original changes in the December driver update.

Radeon Software 18.50 includes both the proprietary and “open” driver stacks. If using the open components, the Mesa build is still derived from Mesa 18.2, as a forewarning. So if you are comfortable in building from Mesa Git or using one of the many third-party package archives for non-rolling-release distros, you’ll be able to find much newer RadeonSI support that way. The AMDGPU DKMS kernel bits are based on Linux 4.18 plus with various patches (namely all the Vega 20 work) added in.

This updated driver can be found at AMD.com. As is standard practice for the AMD packaged driver updates on Linux, towards the end of the quarter (next month), we should see a larger driver update out bringing it onto a new release stream.

And in case you didn’t read our Radeon VII Linux review yet, be sure to do so for a lot of interesting benchmarks while more are on the way.




The Radeon RX Vega Performance With AMDGPU DRM-Next 4.21 vs. NVIDIA Linux Gaming


Given the AMDGPU changes building up for DRM-Next to premiere in Linux 4.21 that is on top of the AMDGPU performance boost with Linux 4.20, here are some benchmarks of Linux 4.19 vs. 4.20 Git vs. DRM-Next (Linux 4.21 material) with the Radeon RX Vega 64 compared to the relevant NVIDIA GeForce competition.

The Radeon RX Vega 64 tests were done with Linux 4.19.5, Linux 4.20 Git as of Saturday afternoon, and DRM-Next-4.21-WIP from Alex Deucher’s Git tree as of Saturday for the latest Linux 4.21 material. The user-space drivers were Mesa 19.0-devel built against LLVM 8.0 SVN via the Padoka PPA. For judging the RX Vega 64 performance were the GeForce GTX 1070, GTX 1070 Ti, GTX 1080, and GTX 1080 Ti graphics cards as the closest competition to Vega. A fresh large graphics card comparison through the RTX 2080 series will be out in the next day or two. There will also be the Radeon RX 590 Linux review still once that graphics card is working appropriately with the driver stack.

The NVIDIA driver in use was 415.18 and all tests were done from the same Ubuntu 18.04 LTS box. All of these OpenGL and Vulkan Linux benchmarks were carried out in a fully-automated and reproducible manner using the open-source Phoronix Test Suite benchmarking software.
