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.

AMD Posts New AMDGPU Patches For UVD Video Decode For GCN 1.0

One of the main blockers from AMD Radeon GCN 1.0 "Southern Islands" GPUs achieving feature parity when using the newer AMDGPU DRM kernel driver rather than the older "Radeon" DRM kernel driver has been in regards to UVD video decoding. But in 2020 it looks like that might finally change.

Radeon Navi 2 "Sienna Cichlid" Published For AMD's OpenGL Driver

Last week AMD's open-source Linux engineers published the initial Linux kernel driver patches for the "Sienna Cichlid" GPU that appears to be almost definitely the big Navi 2. Now that those AMDGPU patches are public, the folks working on the user-space drivers have had the go-ahead to begin volleying their related patches for Sienna Cichlid. Out today is the RadeonSI OpenGL driver support for this next-generation Navi GPU.

AMD Lines Up Another Batch Of Radeon Graphics Fixes For Linux 5.8

Linux 5.8 features for the Radeon "AMDGPU" kernel driver include the likes of Navi soft recovery and better handling of critical thermal faults on Radeon GPUs as well as enabling TMZ support. With feature work being capped off already on the DRM graphics front for Linux 5.8, AMD developers have been tidying up the code and readying more fixes for all of the new code set to premiere with this imminent merge window.

LLVM 11 Merges AMD Radeon GCN Offloading For OpenMP

While AMD has been working on AOMP for Radeon OpenMP offloading as their downstream of the LLVM/Clang compiler suited for GPU compute offloading to their hardware, at least some of that work is beginning to appear back in upstream LLVM.

Patches Proceed For Disabling Radeon AGP GART, Deprecating TTM AGP

Several days back was the proposal to "remove AGP support" from Radeon/Nouveau/TTM. This did formulate into a set of patches that would disable the AGP mode in the Radeon driver and deprecate the AGP code in TTM memory management. However, as was pointed out in the ensuing discussion, AGP graphics cards will still be operable on Linux with this level of deprecation by using the PCI GART mode.

AMD Rethinks Decision And Will Open-Source Most Of Radeon Rays 4.0

Two days ago as part of the GPUOpen relaunch AMD released Radeon Rays 4.0 as their ray intersection library. Unlike the previous Radeon Rays release, however, this new Vulkan-enabled version was not open-source. But now AMD has decided that at least in large part it will be going back to open-source.

GPUOpen Celebrates Another Day Of Its Relaunch With A New Binary-Only Software Release

AMD this week marked the relaunch of GPUOpen as their resource for creators and game developers with their collection of open-source/open-standards minded offerings on the graphics front. In honor of their relaunch, they said they would be issuing new software releases every day this week. It was a bit odd yesterday with Radeon Rays 4.0 dropping their open-source code-base and today they are introducing another new utility that is also binary-only.
