2021 Could Be The Year That AMD Radeon Graphics Can Hot Unplug Gracefully On Linux

It's been nearly one year that AMDGPU patches have been around to better handle GPU hot unplugging on Linux. The use-case for that being either removal via sysfs such as if then assigning the GPU to a VM or for external GPUs such as connected via Thunderbolt. Those patches are still baking but the latest iteration of the work has now been published by AMD.

AMD Sends In More "New Stuff" For Radeon Graphics With Linux 5.12

Sent in last week were many AMD graphics driver updates slated for Linux 5.12 including the likes of Radeon RX 6000 series OverDrive support. This week marks another batch of AMDGPU kernel driver changes being submitted to DRM-Next ahead of the Linux 5.12 cycle.

AMD GPU Driver In Linux 5.12 Gets RX 6000 Series OverDrive, FP16 For More Hardware

The first of several batches of feature updates to the AMDGPU kernel driver were sent in on Friday for anticipation of the Linux 5.12 kernel merge window that should be opening up in February while the stable Linux 5.12 debut will happen likely by/around May. With this initial pull does come some new features and improvements around the recent AMD graphics processor support additions.

AMD Opens Up The Code To Its Radeon Memory Visualizer

Back in May was AMD's celebration of the GPUOpen re-launch and that included the introduction of the Radeon Memory Visualizer (RMV) as their newest tool at the time. But rather strange for being a "GPUOpen" development tool is that it was Windows-only and not actually open-source. Today that has now changed with Radeon Memory Visualizer going open-source.

Linux 5.9.12 Is In Good Shape With The AMD Radeon RX 6800 Series

With my testing of the Radeon RX 6800 series graphics cards last month it's been off Linux 5.10 (aside from when using the Radeon Software for Linux package driver) due to the Linux Git state often offering the best performance and features particularly for brand new hardware. As mentioned in the launch day article for the RX 6800 / RX 6800 XT, there was also an issue being encountered on Linux 5.9. Fortunately, that bug is indeed fixed with the recently released Linux 5.9.12 kernel.

RadeonSI Finally Sees Experimental ACO Patches As Alternative To LLVM Shader Compiler

The Valve-backed ACO shader compiler for Mesa's Radeon Vulkan "RADV" driver has been an enormous success story where this year it's been the default as opposed to AMD's officially supported AMDGPU LLVM shader compiler back-end as pretty much for all major Linux gaming workloads is delivering superior performance. RADV+ACO performance has been so great that gamers have been eager to see the RadeonSI Gallium3D driver also adapted to see ACO as an option to the same AMDGPU LLVM back-end. Well, experimental patches have finally materialized.

Radeon ROCm 3.10 Released With Data Center Tool Improvements, New APIs

While we have been looking out for Radeon ROCm 4.0 that was announced back at SC20 as well as an updated ROCm for providing the RDNA2 compute support only found currently in their packaged RX 6800 series Linux driver, ROCm 3.10 arrived on Wednesday as an unexpected twist.
