Radeon Pro Software for Enterprise 20.Q3 Released For Linux

AMD has released their Radeon Pro Software for Enterprise 20.Q3 driver as their quarterly update to this enterprise-rated driver for their professional/workstation graphics offerings. In step with the new Windows driver release is also the 20.Q3 packaged Linux driver for enterprise distributions including RHEL/CentOS 8.1, RHEL/CentOS 7.8, Ubuntu 18.04.4, and SUSE SLED/SLES 15.

R600 Gallium3D Now Has Compute Shaders Working With NIR

If you are still rocking a pre-GCN AMD Radeon graphics card on the R600g driver for the HD 2000 through HD 6000 series, you really ought to consider upgrading in 2020, but otherwise at least from the open-source community there continues to be improvements.

Radeon Software for Linux 20.30 Released

Just under two months since Radeon Software for Linux 20.20 that is comprised of the AMDGPU-Open and AMDGPU-PRO driver components for these packaged drivers, Radeon Software for Linux 20.30 was quietly released at the end of last week.

RADV ACO Back-End Begins Tackling Navi 2 / GFX10.3 Support

With the "Sienna Cichlid" and "Navy Flounder" open-source driver support as what appear to be the first "Navi 2" GPUs and the first of the "GFX10.3" generation on the graphics engine side there is the initial kernel support with Linux 5.9 and the initial Mesa support for 20.2. That Mesa support has been focused on RadeonSI as the official OpenGL driver as well as Mesa's RADV driver as the Radeon Vulkan driver in-tree but not officially supported by AMD. That RADV support is currently un-tested. Both drivers currently depend upon the "AMDGPU" back-end found in the forthcoming LLVM 11.0 with its initial GFX10.3 support. But now on the RADV driver side there is preliminary GFX10.3 bits landing for the popular "ACO" back-end.

Defaulting Radeon GCN 1.0/1.1 GPUs To Better Linux Driver Is Held Up By Analog Outputs

Switching from the "Radeon" to "AMDGPU" kernel driver on Linux is possible for Radeon GCN 1.0/1.1 era graphics cards and doing so can mean slight performance benefits, the ability to run the AMDVLK or RADV Vulkan drivers, and simply making use of this better maintained driver. But having these original GCN graphics cards default to the modern AMDGPU driver appears held up by the lack of analog video output support with that driver.

ACO Radeon Shader Back-End Adds Unit Testing Framework To Help Test Optimizations

The popular "ACO" shader compiler back-end that recently was promoted to the default shader compiler for Mesa's open-source Radeon Vulkan driver (RADV) has long been testing with shaders and traces while now a proper unit testing framework is being introduced for verifying optimizations are correctly handled, ensuring no regressions, etc.

Radeon R600 Gallium3D NIR Backend Continues Advancing

While the open-source Radeon Linux graphics driver allows pre-GCN AMD graphics card owners continue making use of their graphics cards, there are diminishing returns with newer games requiring Vulkan that is not supported by pre-HD7000 series hardware as well as far greater performance and efficiency improvements in the more recent generations. In any case, if you are still using a Radeon HD 2000 through HD 6000 series graphics card, some new life is being pushed into the open-source driver via the in-development NIR back-end.

AMD Publishes AMDGPU UVD Firmware For Southern Islands

Recently AMD posted UVD video decode support for GCN 1.0 with the AMDGPU driver, one of the long holdouts for letting the AMDGPU DRM driver approach feature parity with the longstanding Radeon DRM driver that is the default for GCN 1.0/1.1 era GPUs. That AMDGPU UVD GCN 1.0 decode support is going into the Linux 5.9 kernel later this summer after years ago Radeon driver developers largely dismissed the efforts of porting the UVD decode capability for these original GCN graphics cards over to AMDGPU.

AMDGPU Patches Revived For Better Hot Device Unplug / External GPU Handling

More than one month ago we reported on AMDGPU patches proposed for better hot unplug handling, mainly for the use-case of external GPU solutions if disconnecting them while the system is still running to avoid a range of show-stopping problems. It's been a quiet few weeks but that work has now seen a new revision.
