Earlier today I wrote about how AMD will only be supporting Vulkan with the AMDGPU DRM kernel driver and not the more common Radeon DRM kernel driver. Here's a few more points to clarify the situation.
I've just received confirmation from AMD that their forthcoming Vulkan driver will only work with the AMDGPU DRM kernel driver. This means that unless this AMDGPU kernel driver is extended to support pre-VI hardware, only the very latest AMD GPUs on Linux will work with Khronos' next-generation API.
While the Radeon DRM driver has had support for doing GPU resets in case of hangs, the AMDGPU DRM driver for newer graphics processors haven't had this feature.
It looks like the merging of AMD HSA (Heterogeneous System Architecture) support into the GCC compiler is imminent.
AMD appears poised to announce their long-awaited A1100 "Seattle" ARMv8 processor tomorrow.
Months after Axel Davy originally posted his patch-set for the SI machine scheduler to enhance the performance of AMD GCN GPUs on the open-source driver, it looks like the code will soon land in the AMDGPU LLVM back-end.
As of a few days ago in the latest LLVM development code is support in the AMDGPU back-end for using the new linker.
With the Linux 4.5 merge window's hwmon subsystem pull request is an update for new AMD Family 15h processors to support power monitoring.
With this morning's article about New AMDGPU Details and Looking Forward To Major Radeon Linux Improvements In 2016, there is much to be excited about with the new driver model finally set to roll-out and other open-source projects coming about. However, if you are a relatively new Linux users, you may not know how this whole process began.
With the merge window expected to open next week for the Linux 4.5 kernel, AMD's Alex Deucher has sent some more last-minute work into DRM-Next.
New patches have been posted by an AMD engineer for exposing accumulated power reporting.
Just ahead of CES, AMD/RTG is allowing more details on their next-generation Polaris GPU architecture to be revealed.
AMD's open-source graphics driver stack continued maturing in 2015 while Catalyst (now known as Radeon Software) releases were rare. AMD's open-source driver stack now supports OpenGL 4.1 for GCN GPUs and select pre-GCN graphics cards plus the other driver stack also matured in other ways this year.
While I've been writing a lot the past few days about the AMDGPU kernel driver given it's landing PowerPlay support for Linux 4.5, I took some time today for running some Radeon (non-AMDGPU) DRM tests to see if the performance of this DRM-next code has changed compared to Linux 4.4 near-final.
If you are anxious to help test out the new changes of the Radeon and AMDGPU kernel drivers that will be added to Linux 4.5, I've spun up a kernel for Ubuntu x86_64 systems to try out this experimental code.
While Linux 4.5 brings support for PowerPlay in the AMDGPU DRM driver to allow the modern discrete Radeon graphics cards to run much faster thanks to re-clocking, this major feature isn't being enabled by default for Linux 4.5.
Just minutes after writing about how AMDGPU PowerPlay support made it into AMD's drm-next-4.5 branch, that Git branch is now called for pulling into DRM-Next. Besides the PowerPlay support for the latest Radeon GPUs, there are also a number of other changes.
Alex Deucher has been tidying up his drm-next-4.5 branch for merging the Radeon and AMDGPU DRM driver changes into DRM-Next.
Following the release of Radeon Software Crimson 15.12 for Windows, Radeon Technologies Group has now released Radeon Software Crimson Edition 15.12 for Linux.
For those with an AMD Tonga or Fiji graphics card that want to try out the latest open-source AMDGPU kernel driver code with PowerPlay support enabled, here's an easy-to-use Ubuntu/Debian kernel spin.
As of earlier this month in Mesa Git is finally OpenGL 4.0 and 4.1 support for the Radeon R600g driver for pre-GCN hardware, albeit the subset capable of advertising GL4 compliance is right now just Cypress and Cayman. I took this opportunity to run some fresh Mesa Git benchmarks on an AMD Cayman GPU and a third run when enabling DRI3.
AMD this morning is lifting an embargo on GPUOpen, a new effort for embracing open-source with their Linux drivers.
While I ended up returning my AMD A10-8700P "Carrizo" laptop due to its faulty fan, I did run a few benchmarks of it prior to sending it back. Here's roughly what you can expect in terms of its performance against Intel Core i3 and i5 laptops.
Smach Z, the portable/handheld Steam Machine powered by Linux, is moving ahead and hopes to launch to market this time next year.
HyperZ support in the open-source Radeon Gallium3D drivers has been a bumpy road to say the least but it looks like some more improvements are imminent.
AMD's R600 Gallium3D driver just made it up to OpenGL 4.1 support (for the few select GPUs that provide the necessary capabilities), but things aren't stopping there with another OpenGL 4.3 extension now landing.
Just one week after talking about progress being made with AMD tessellation support for pre-GCN GPUs, the support has been finally added to Mesa Git!
Alex Deucher on Friday sent out the latest patches for implementing ASoC support for AMD APUs. These patches provide i2s audio support via a new driver and integrates with the AMDGPU DRM.
For those excited to see some AMD A10-8700P "Carrizo" notebook benchmarks on Linux, here are a few numbers.
A Phoronix reader pointed out an interesting slide deck that's gone relatively unnoticed up until now about a game developer "Hacking GCN via OpenGL" for allowing some interesting possibilities.
