AMD today released its third and last open-source Vulkan driver update of the quarter.

AMD open-source Linux driver patches posted last summer enabled the new "VPE" IP block as a general purpose copy engine for future AMD GPUs. This VPE block might premiere in the upcoming AMD RDNA3.5 refresh (RDNA3+) integrated graphics but in any event AMD is already working on the incrementally improved VPE 1.1 IP with that now being supported by the Mesa 24.1 RadeonSI driver code.

It was just last week that Tiny Corp put their AMD Radeon graphics powered compute boxes "on hold" after being frustrated with the lack of select firmware source code and ultimately hitting various bugs. This wasn't the first time they had put their AMD Radeon graphics plans on-hold or dismissed it outright. With the start of the new week now comes plans to re-introduce an AMD Radeon graphics option for their compute boxes alongside their recently announced NVIDIA GeForce RTX 4090 compute rigs.

The AMDGPU Linux driver up until the recent Linux 6.7 kernel release has let you lower the power limit of your graphics card with, well, no limits... This has allowed AMD Radeon Linux users to limit their GPU power draw when desiring for power/efficiency reasons. But since Linux 6.7 they've begun enforcing a lower-power limit set by the respective graphics card BIOS. Users petitioned to have this change reverted but in the name of safety this lower-limit enforcement will stand.

When it comes to the AMD "RDNA3 Refresh" GFX11.5 open-source driver support, to date it's mostly been focused on the GFX 11.5.0 (GFX1150) IP while now being enabled within Mesa 24.1 for the open-source RadeonSI/RADV drivers is support for a GFX 11.5.1 (GFX1151) variant.

With the absence of any official AMD Radeon graphics control panel / settings GUI for Linux enthusiasts/gamers, there are several open-source projects striving to be a viable Radeon GUI control area for Linux gamers/enthusiasts.

Back in 2020 AMD rolled out a video mode optimization for FreeSync on Linux, continued being revised in 2021, FreeSync Video mode then attempted by default in 2022 but then was reverted and then only last year FreeSync Video enabled by default. But now come Linux 6.9, the feature appears to be effectively retired.

Building upon the existing AV1 encode support for RDNA3 GPUs within the Mesa RadeonSI Gallium3D driver, AV1 Long-Term Reference "LTR" support is now enabled within Mesa 24.1.

One of the limitations of AMD's open-source Linux graphics driver has been the inability to implement HDMI 2.1+ functionality on the basis of legal requirements by the HDMI Forum. AMD engineers had been working to come up with a solution in conjunction with the HDMI Forum for being able to provide HDMI 2.1+ capabilities with their open-source Linux kernel driver, but it looks like those efforts for now have concluded and failed.

It looks like AMD will soon be announcing the ROCm 6.1 update to its open-source GPU compute stack.

In recent weeks there have been a lot of open-source AMD Radeon graphics driver patches flying around for the GFX12 graphics engine, Video Core Next 5, and other new graphics intellectual property (IP) blocks that appear to be for next-generation "RDNA4" Radeon graphics. This week yet more patches have been posted publicly.

AMDVLK 2024.Q1.1 has dropped as AMD's first open-source Vulkan API driver release of the new year for Radeon graphics on Linux.

Earlier this month the GCC 14 compiler landed initial support for AMD RDNA3 "GFX11" graphics processors as part of the GNU Compiler Collection's OpenMP device offloading support for GPU compute. That initial support was rather basic but a follow-up patch has the possibility of making the RDNA3 (GFX11) support "working for most purposes" and will hopefully still be merged in time for the GCC 14.1 stable release.
