17 Fresh AMDGPU DC Patches Posted Today

Seventeen more "DC" display code patches were published today for the AMDGPU DRM driver, but it's still not clear if it will be ready -- or accepted -- for Linux 4.12.

AMD developers posted 17 new DC (formerly known as DAL) patches today to provide small fixes for Vega10/GFX9 hardware, various internal code changes, CP2520 DisplayPort compliance, and various small fixes.

These latest patches can be found for review via amd-gfx list. What remains to be seen though is if AMDGPU DC will be ready for Linux 4.12, which is now more pressing since Radeon Vega support needs it. This weekend we'll see Linux 4.11-rc4 released and so that probably leaves two weeks or less (especially with Linus Torvalds being upset by late DRM-Next merges, especially after the 4.11 merge window controversy) for AMD developers to try to push the DC code through another final review and see if a pull request into DRM-Next would be honored by David Airlie.

Aside from being needed for Vega support, AMDGPU DC finally lays the framework for other modern display features like HDMI 2.0, FreeSync (although that's not fully wired up yet on the open code), HDMI/DP audio support, and atomic mode-setting. Stay tuned to Phoronix to find out if it gets lined up for Linux 4.12 or will be held off for yet another cycle.
