AMD HSA IL / BRIG Front-End Still Hoping To Get Into GCC 7

For many months now there's been work on an AMD HSA IL front-end for GCC with supporting the BRIG binary form of the Heterogeneous System Architecture Intermediate Language (HSA IL). It's getting late into GCC 7 development and onwards to its final development stage while this new front-end has yet to be merged.

Linux 4.10 Is Hopefully In Good Shape For AMD Zen / Ryzen Processors

AMD's upcoming Ryzen (Zen) processors appear to be in good enough shape that they are working on the current mainline kernel as far as I can tell based upon limited information available prior to getting my hands on the CPUs or getting any official announcement from AMD, but some Linux kernel patches have yet to be mainlined. The yet-to-be-merged work appears to be more for non-core features and Zen server functionality with those CPUs shipping later than the upcoming Ryzen desktop CPUs.

The Strange Behavior Of My Radeon R9 290 Is Still There

In recent days there have been a few Phoronix readers inquiring why I am not testing with my Radeon R9 290 graphics card in all our frequent comparisons and driver benchmarks. The short story is that the regression since Linux 4.7 remains and for my Radeon R9 290 and others with select Hawaii graphics cards, there still is a performance regression. Though over Christmas I hope to finally find the time to bisect it.

AMD MxGPU Virtualization For The AMDGPU Driver

Well this weekend is exciting for AMDGPU users and open-source AMD fans. Yesterday was the news we published about Valve looking to improve AMDGPU/RADV for their Vulkan-based VR experience while the latest is work from AMD that implements GPU virtualization support within the AMDGPU driver.

AMD "DAL" Being Renamed To "DC"

AMD's big display abstraction layer (DAL) code-base that's used by AMDGPU-PRO but not yet mainlined in the Linux kernel for providing HDMI 2.0, future FreeSync/Adaptive-Sync, HDMI/DP audio, and other modern display features is DAL no more.

It Looks Like We'll Still See A GUI Control Panel For AMD Linux

Earlier this year I exclusively reported on the "Radeon Settings" GUI control panel may be open-sourced for AMD Linux users but since then I hadn't heard anything publicly or privately about getting this graphics driver control panel on Linux for AMDGPU-PRO and the fully-open AMDGPU stack. But it looks like that it's still being worked on internally at AMD.

OpenCL Remains One Of AMDGPU-PRO's Main Advantages, Can't Wait For It To Be Open

While many in our forums and other Linux communities want to see "AMDGPU-PRO die" or for AMD to stop supporting the hybrid/proprietary driver given the pace of RadeonSI development for OpenGL and the emerging RADV for (unofficial) Vulkan support, OpenCL remains one of AMDGPU-PRO's strongholds. AMD has been working on opening up their proprietary compute stack, but for now it's there. Here are some fresh AMDGPU-PRO 16.40 benchmarks versus NVIDIA in LuxMark, one of the real-world OpenCL workloads where the AMD blob does very well.

AMD's DAL Was Just Presented At XDC2016, Still Not Clear When It Will Be Mainlined

Harry Wentland of AMD just presented at the XDC2016 conference about DAL, the big Display Abstraction Layer code-base, which many AMD Linux users have been waiting to see merged in order to have Polaris audio support and this is one of the stepping stones for seeing FreeSync/Adaptive-Sync and other modern display capabilities.

More AMD PowerPlay Fixes Queued For Linux 4.9

The AMDGPU DRM code for Linux 4.9 is already queued in DRM-Next with virtual display support and other features as well as experimental GCN Southern Islands support while today another feature pull request was submitted to DRM-Next with more Radeon/AMDGPU changes.

Southern Islands Support Will Come To AMDGPU On Linux 4.9

One month after the first AMDGPU feature pull of new functionality for DRM-Next to in turn land in Linux 4.9, the second feature pull request has now been sent out and it presents experimental Southern Islands (GCN 1.0) support for AMDGPU.

Linux+Mesa Git Remains Problematic For Some Regressed R9 290 GPUs

Last week a Mesa fix landed to target the Radeon R9 290/390 performance regression that's been covered a few time on Phoronix since the issue was originally noticed. While the Mesa fix is working for some users, it didn't fix all problems, including with my Hawaii test card.

AMD's GPUOpen HIP Project Made Progress Over The Summer

The HIP project has made good progress over the summer. HIP from AMD's GPUOpen project is part of the puzzle for converting CUDA to portable C++ code. That source code can then run on AMD GPUs while having little to no performance impact, at least according to AMD.
