R600 Gallium3D To End Code Sharing With RadeonSI Driver

While the R600g and RadeonSI drivers are two distinct Gallium3D drivers for R600 (HD 2000) through Northern Islands (HD 6000) and GCN and newer, respectively, they have up until now shared some code via gallium/radeon. But that will now be ending.

Early Work Bringing VCE1 Video Encode To AMDGPU DRM

There's more good news about work-in-progress patches for those GCN 1.0 owners that have been looking to get your graphics card running full-featured under the AMDGPU DRM driver rather than the existing Radeon Direct Rendering Manager driver.

RadeonSI Lands Primitive Binning Support For Vega

With a goal of increasing performance, AMD developers have added support for primitive binning to the RadeonSI Gallium3D driver. However, it's not yet known if it will actually help the RX Vega performance.

Work-In-Progress Porting Of GCN 1.0/1.1 UVD To AMDGPU DRM Driver

With the experimental AMDGPU DRM driver's support for GCN 1.0 "Southern Islands" and GCN 1.1 "Sea Islands" graphics processors as an alternative to the default Radeon DRM driver, one of the disadvantages of that experimental kernel driver is losing out on UVD video decoding. But a port is in the works.

FP64 Support Revised For R600g Gallium3D Driver

While the Radeon HD 5000/6000 series were advertised as supporting up to OpenGL 4.4 and are supported that way by the Catalyst / Radeon Software proprietary driver, the Mesa R600g driver has only exposed OpenGL 3.3 (with the exception of the HD 5800 / 6900 series) due to lacking FP64 support. That emulated FP64 support is now stepping ahead for the R600g driver.

Vega 10 Huge Page Support, Lower CS Overhead For AMDGPU In Linux 4.14

With this weekend marking the ending of David Airlie accepting new feature material for DRM-Next to in turn land in the Linux 4.14 cycle in a few weeks, there's a rush by Direct Rendering Manager driver maintainers to submit the last of their new feature work of changes they want in this next kernel release.

Radeon X.Org Driver Gets Fixed Up To Always Allow Page-Flipping With TearFree

It's fairly rare these days seeing improvements to the xf86-video-ati DDX: the driver for those running a pre-AMDGPU (GCN 1.2) graphics card with this driver paired with Radeon DRM and not using the generic xf86-video-modesetting driver instead. But if you are using xf86-video-ati and use the "TearFree" feature to try to avoid screen tearing, a number of patches landed today.

Trying amd-staging-drm-next With The Radeon RX Vega

With my Radeon RX Vega benchmarks so far this week I have been using the amd-staging-4.12 tree that contains the DC display code and Vega support. Though even with fresher code is amd-staging-drm-next, so here are some benchmarks.

AMDGPU DC Display Code Gets A Public TODO List

For those anxious to see AMDGPU's DC / DAL / display code mainlined either for the Radeon RX Vega support, FreeSync capabilities, HDMI/DP audio, or other display features, there is now a public TODO list.

ROCm OpenCL Is Still Getting Ready To Rock For Vega

With the just-posted Radeon RX Vega 56 / 64 Linux review, there aren't any OpenCL benchmarks due to some issues encountered in the process. When the Vega OpenCL support is in better shape, results will be published. But for those anxious to see anyways what the current ROCm OpenCL performance looks like for Ethereum with Ethminer, here's a quick look.

Radeon Vega Pro Introduces A "AMD Secure Processor"

The embargo just expired on the Radeon Pro Software Crimson ReLive Edition for Vega Radeon Professional Graphics. There isn't much to share from the Linux driver side, except worth noting that Vega Pro graphics hardware has a "secure processor" onboard.
