Direct GPU <-> GPU communication does not seem to work properly

[Public] Hi Morgan ,

Thanks for filing a bug ticket . This is a known issue to us . Your observation is correct that the P2P report was once broken on all R545 series . R535 , R550 and go on for later releases , it is fixed .
We feel sorry for the breakage . But we have no more plan to backport fixes to R545 , please move forward with R550 drivers .

Hope this helps.

Best,
Yuki
