More Than 100 More AMDGPU DC Patches Line Up Ahead Of Linux 4.15

AMDGPU DC is expected for Linux 4.15 assuming Linus Torvalds has no objections to merging the code. We hope it won't, but the code-base for this new AMD display code is outright massive at more than 120,000 lines of code over hundreds of patches. Today another 103 new patches were published.

A New Ubuntu Kernel Build With The Very Latest AMDGPU DC Patches For 4.15

This week the latest AMDGPU DC patches were queued up ahead of Linux 4.15. As covered in that article, those several dozen patches mostly further clean-up this major AMDGPU display code rework and trim it up by a few thousand lines of code. For those wishing to test out this new display stack, here is a fresh Ubuntu/Debian x86_64 kernel build.

An Ubuntu Kernel Spin Of AMDGPU DC "drm-next-4.15-dc"

Yesterday was the very exciting news of the AMDGPU DC code finally being called for pulling to DRM-Next for integration in the Linux 4.15 kernel. So far it's looking like that will indeed happen for Linux 4.15 assuming Linus Torvalds has no objections. If you want to test out this kernel for HDMI/DP audio, Radeon RX Vega display support, atomic mode-setting, or other modern features, here is an Ubuntu kernel spin.

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.
