A Fresh Kernel Spin For Those Wanting To Use RX Vega On Linux Or AMDGPU DC

For those running Ubuntu/Debian and wanting a kernel with the very latest AMDGPU DRM support along with the very bleeding edge DC display code patches, I've done a fresh spin today in preparation for my latest RadeonSI/RADV Vega benchmarking.

You'll need this kernel (or a similar DC patched kernel, unless using AMDGPU-PRO) if wanting to use a new Radeon RX Vega graphics card connected to a monitor or if wanting to use HDMI/DP audio, FreeSync, or other modern display features atop the AMDGPU Direct Rendering Manager.

In the few weeks since my last kernel spin, there have been new DC patches to be queued up in Alex Deucher's tree plus other AMDGPU patches in general.


This Ubuntu x86_64 kernel build was assembled today from the amd-staging-drm-next branch while building the kernel with the AMDGPU DC Kconfig switches enabled. That kernel in turn is based off a 4.13-rc5 snapshot for the time being.

Besides the patched kernel, keep in mind you also need the latest linux-firmware.git, LLVM 5.0 or newer, and ideally the latest Mesa Git code for best support. More details in our RX Vega Linux guide.


Keep in mind these latest DC patches are still under going testing, so proceed at your own risk, but if you want an easy way to test the latest AMDGPU DC support you can try out linux-image-4.13.0-rc5-phx-amdgpudc_4.13.0-rc5-phx-amdgpudc-1_amd64.deb.
