Following the weekend news of the AMDGPU kernel driver becoming too large that it's causing the Plymouth boot splash screen on slower Linux systems to time-out, longtime AMD Linux graphics driver engineer Marek Olšák expressed a new idea for helping to reduce some bloat from this AMD kernel graphics driver.

The modern AMD kernel graphics driver "AMDGPU" is the biggest driver within the mainline Linux kernel and is approaching six million lines of code albeit a large chunk of that is made up of auto-generated header files for each supported GPU. But this AMDGPU kernel driver is becoming "really really big" that it's beginning to cause issues for Plymouth that commonly provides the initial boot splash screen experience on modern Linux desktops.

AMD today committed their GC 11.5.2 firmware to the upstream linux-firmware.git for the necessary firmware binary blobs needed for hardware initialization by their open-source AMDGPU kernel graphics driver with this newer RDNA3.5 variant.

We are just a week or two out from the start of the Linux 6.12 merge window and AMD has submitted a final round of feature updates to DRM-Next of kernel graphics driver changes they want to round out AMDGPU/AMDKFD for this next cycle.

Sent out today were the DRM fixes for 6.11-rc7 ahead of the Linux 6.11-rc7 kernel being released on Sunday. As usual most of the changes revolve around the AMDGPU and Intel i915/Xe drivers plus random fixes to the smaller drivers. There is one change though with the AMD Radeon graphics driver side worth highlighting to address a performance regression affecting recent kernels.

Following the AMDVLK 2024.Q3.1 driver release from earlier in the month, AMDVLK 2024.Q3.2 is now available as the latest update to this official open-source AMD Radeon Vulkan driver for Linux systems.

A big set of patches have been submitted for DRM-Next of "new stuff" to the AMDGPU kernel graphics driver and the AMDKFD compute driver with the upcoming Linux 6.12 kernel cycle.

With Mesa's RADV driver supporting Vulkan Video for accelerated video encode/decode using this cross-platform, industry standard API it hasn't been exposed by default for RDNA3 graphics processors bearing VCN4 IP. That has now changed for Mesa 24.3 when using the latest VCN4 firmware.

It's not too often these days seeing new OpenGL extensions come to Mesa drivers given their already robust coverage and not many new OpenGL extensions being introduced compared to the still-expanding Vulkan APIs. Overnight though RadeonSI Gallium3D saw GL_KHR_shader_subgroup support land.

A set of a dozen patches have reworked the video encode handling within Mesa 24.3 for the Video Acceleration (VA) front-end and the RadeonSI/VCN driver code. This rework aims to enable new features moving forward, enhance the overall driver, and bring "significant" memory savings for H.265/HEVC video encoding.

The Vulkan Video support within Mesa's Radeon "RADV" Vulkan driver continues to be improved upon. The newest addition now found in the code for Mesa 24.3 is enabling 12-bit AV1 content accelerated decoding.

A set of patches posted today on the AMD graphics driver mailing list begin implementing support for process isolation within the AMDGPU kernel graphics driver.

Hitting the release button minutes ago, AMDVLK 2024.Q3.1 is available as the newest version of AMD's official open-source Vulkan driver and the first new release since the end of June. This driver continues to trail in popularity to the likes of the Valve-backed Mesa RADV Radeon Vulkan driver but does well in areas like Vulkan ray-tracing and is officially backed by AMD.

Back in February of this year you may recall the interesting news that was announced on Phoronix that AMD Quietly Funded A Drop-In CUDA Implementation Built On ROCm: It's Now Open-Source. That open-source ZLUDA code for AMD GPUs has been available since AMD quit funding the developer earlier this year. But now the code has been retracted. It's not from NVIDIA legal challenges but rather AMD reversing course on allowing it to be open-source.

A number of GPU hang fixes have been merged for AMD's RadeonSI Gallium3D driver within Mesa. These fixes should help further enhance the current RDNA3 GPU driver support and also has fixes for stabilizing the upcoming RDNA4 GPU support.

AMD engineers posted a set of patches today for enabling VCN IP DUMP support with their open-source AMDGPU kernel driver. This allows for dumping the IP state of all Video Core Next (VCN) hardware from VCN 1.0 through VCN 5.0.

Last August I wrote an article about the open-source AMD GPU kernel driver crossing 5 million lines of code -- including their overzealous header files -- and following the recent Linux 6.11 merge window curiosity got the best of me with how much larger the kernel driver is now that the initial RDNA4 support is merged... Well, it's about to cross 5.8 million lines, or about a 16% increase just over the past year.

As expected, AMD has released ROCm 6.2 as the newest version of their open-source GPU compute stack for Radeon graphics cards and Instinct accelerators. ROCm 6.2 is a big update with several new software components, improving the existing PyTorch and TensorFlow support, and a variety of other enhancements as AMD works to better compete with NVIDIA's CUDA.

As I noted in yesterday's AMD Ryzen AI 9 HX 370 review and in particular the new RDNA3.5-based Radeon 890M graphics, I used updated DMCUB firmware with the open-source Linux graphics driver stack to workaround some screen freezes and kernel errors initially experience while using the Linux 6.10 kernel. That updated DMCUB firmware is now public within the upstream linux-firmware.git repository for those that may be picking up a new AMD Ryzen AI laptop with RDNA3.5 graphics in the coming days.

While the hope remains that GPU resets are a very infrequent task, AMD Linux driver engineers have recently been working on the ability to support a per-queue GC reset capability for more precise reset capabilities when needed.

The latest video acceleration improvements to report on with the open-source AMD Radeon driver front is support in Mesa 24.3-devel for passing HDR metadata in the AV1 encoder.

We appear to be on the heels of the AMD ROCm 6.2 software release for advancing the open-source AMD Radeon/Instinct GPU compute stack with new features.

It looks like the AMD RDNA4 "GFX12" graphics driver support is in good shape: AMD is now enabling the driver support for the next-generation graphics "out of the box" with the latest pending patches.

While there have been various efforts like HIPIFY to help in translating CUDA source code to portable C++ code for AMD GPUs and then the previously-AMD-funded ZLUDA to allow CUDA binaries to run on AMD GPUs via a drop-in replacement to CUDA libraries, there's a new contender in town: SCALE. SCALE is now public as a GPGPU toolchain for allowing CUDA programs to be natively run on AMD graphics processors.

Last week it was noted AMD would be squeezing in more patches for "new IPs" to "get them tied off" with the upcoming Linux 6.11 cycle. This is principally about RDNA4 support and sure enough on Friday more patches were submitted to DRM-Next.
