AMD Adding More Radeon Graphics Drivers Code For Linux 5.6


AMD adding more Radeon Graphics Drivers code for Linux 5.6.

This latest batch of AMDGPU material for Linux 5.6 builds off the interesting feature work of previous weeks and now includes.

  • The AMDKFD compute kernel code now spreads interrupt work across CPU cores to help reduce latency.
  • Display Core Next (DCN) support for working on IBM POWER, so the latest AMD graphics cards should play nicely on the likes of Raptor Computing Systems' libre POWER9 hardware systems.
  • GFXOFF support is now enabled for Raven 1 refresh APUs for being able to conserve power by turning off the graphics engine when it's not in use.
  • A reusable task barrier for synchronizing a given number of threads at a point before execution of critical code. This DRM task barrier support is initially being used within the xGMI hive code.
  • HDMI 2.0 audio fixes.
  • Continued fixes/improvements around Renoir.
  • Continued fixes for the yet-to-launch Arcturus GPU with Video Core Next, BACO (Bus Active, Chip Off), and other fixes.

Various other fixes and clean-ups, which can be found here via the mailing list post.
