A few days ago I wrote about David Airlie's work on a new "r600-rats" branch where he's working on bringing up OpenGL 4.2 support to more Radeon HD 5000/6000 series hardware on R600g that's currently limited to OpenGL 3.3. Some questions arose about the FP64 support...
While the ROCm OpenCL code was recently open-sourced, that new Radeon OpenCL code only supports newer GPUs like Fiji and Polaris and experimental support for "GFX7" GPUs like Hawaii. Due to this newer OpenCL stack, AMD hasn't been investing in the "Clover" Gallium3D state tracker for providing OpenCL within Mesa. But there are at least some independent developers interested in still working on this older OpenCL code for previous Radeon GPUs, including pre-GCN hardware with R600g...
The openSUSE Conference 2017 kicked off yesterday in the beautiful Nürnberg, Bavaria. The event runs through Sunday but if you are sadly missing out on the event, there are video live streams and recordings available...
Earlier this month we reported on patch work done to bring Intel's BLORP blitting framework to older Intel graphics hardware and now that work has landed in Git for Mesa 17.2...
In yesterday's GeForce GT 1030 Linux review, a $70 USD graphics card that's low-profile and passively-cooled, I featured a number of NVIDIA VDPAU video acceleration benchmarks. But a question came up about Radeon VDPAU performance, so here are some benchmarks on that front, but they are far from ideal.
Days ago was a discussion about dropping older Mesa drivers from mainline while issued now is a more formal proposal for branching off older drivers, including i915g and R300g, among others...
If you are looking for a low-profile, passively-cooled graphics card, the GeForce GT 1030 launched last week and MSI is out the door with such a capable graphics card while only costing around $70~80 USD. Here are some Linux OpenGL, Vulkan, OpenCL, and VDPAU video acceleration benchmarks of the MSI GeForce GT 1030 compared to various other Radeon and GeForce graphics cards under Ubuntu.
AMD developers have landed their work on supporting VCN video decoding in Mesa. VCN is the new video decode engine with the upcoming Raven Ridge APUs (Zen CPU + Vega Graphics) that apparently succeeds the UVD video decoding block...
Florian Müllner has pushed out an updated Mutter 3.25.2 window manager / compositor release in time for the GNOME 3.25.2 milestone in the road to this September's GNOME 3.26 release...
Arcan 0.5.2 has been released as the newest version of the open-source display server project built in part using a game engine that has also been working on X.Org and Wayland compatibility...
David Airlie is breathing some new open-source life into older Radeon GPUs with his "R600g-Rats" branch where he's bringing OpenGL 4.2 and other features to this older driver...
It was just with GCC 6 that MPX support was flipped on with Intel's Memory Protection Extensions (MPX) just premiering with Skylake CPUs. But now GCC developers are thinking about potentially deprecating this feature...
Merged last month into Mesa Git and improved since then with follow-up commits has been KHR_no_error support for reducing the overhead of the OpenGL drivers by disabling certain error handling for OpenGL games/applications. This in turn can free up some CPU utilization and possibly lead to power-savings too...
With Btrfs RAID 5/6 seeing fixes in Linux 4.12, if you are re-evaluating the setup of a Btrfs native RAID array, here are some fresh benchmarks using four solid-state drives.
AMD's Harry Wentland has sent out the latest round of patches to the yet-to-be-merged DC display stack (formerly known as "DAL") for the AMDGPU kernel driver...
Igalia developers have been working on improvements to better supporting Google's Chromium/Chrome web-browser under Wayland and should eventually be upstreamed...
Nicolai Hähnle is looking at adding support for ARB_gl_spirv to the RadeonSI Gallium3D driver and as part of that support for the NIR intermediate representation...
Heterogeneous Memory Management sadly didn't make it for Linux 4.12 as developer Jerome Glisse was aiming for, but now he's out with an updated version to these important HMM patches...
RISC-V developers believe that while their Linux kernel port isn't yet fully complete, they are hoping to get it mainlined now for this open-source CPU ISA...
