Nice feature. Minor man page glitch = the line starting with 'on' in the
patch snippet below doesn't show up when viewed with man amdgpu.
+Set the default value of the per-output 'TearFree' property, which controls
+tearing prevention using the hardware page flipping mechanism. TearFree is
+on for any CRTC associated with one or more outputs with TearFree on. Two
+separate scanout buffers need to be allocated for each CRTC with TearFree
+on. While TearFree is on for any CRTC, it currently prevents clients
+DRI page flipping. If this option is set, the default value of the
+'on' or 'off' accordingly. If this option isn't set, the default value
+which means that TearFree is on for outputs with rotation or other RandR
+transforms, and for RandR 1.4 slave outputs, otherwise off.
