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.

With Alex Deucher's drm-next-4.15-dc Git branch as of this morning, I built this latest code for AMDGPU DC testing. This is useful if wanting to use Radeon RX Vega graphics cards on Linux, HDMI/DP audio with newer Radeon GPUs, atomic mode-setting, or other modern display features.

With this code for 4.15, DC is automatically used for Raven/Vega GPUs but for others you need to boot the kernel with amdgpu.dc=1 for enabling the new display code path. Of course, test at your own risk.

I'll have some new Vega Linux benchmarks, etc, up soon paired with the latest Mesa Git happenings.

You can grab this fresh kernel spin from phoronix.net/downloads/drm-next-4.15-dc-2.
