The tearing occurs because amdgpu doesn't support scatter/gather scanout with Raven yet, so page flipping cannot be used.
For the time being, you can get rid of the tearing by enabling TearFree:
xrandr --output eDP --set TearFree on
See the amdgpu (4) manpage for more information about TearFree.
Also i forgot to ask. Isnt there an time estimate when can we expect scatter scanout support for Raven ?
