I'm pleased to announce the 1.3.0 release of xf86-video-amdgpu,
Highlights:
* Allow TearFree to be toggled at runtime via an RandR output property
"TearFree". The xorg.conf option "TearFree" now controls the default
value of the output properties.
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
from using
+DRI page flipping. If this option is set, the default value of the
property is
+'on' or 'off' accordingly. If this option isn't set, the default value
of the
+property is
+.B auto,
+which means that TearFree is on for outputs with rotation or other RandR
+transforms, and for RandR 1.4 slave outputs, otherwise off.
