From: Jiadong Zhu <Jiadong.Zhu@xxxxxxx> Gfx9 is using software rings which would trigger mcbp in some cases. Thus the parameter amdgpu_mcbp shall be enabled by default.
Actually the idea was to not need the amdgpu_mcbp parameter any more and deprecate it with the use of the software rings.
Why is that still necessary? Regards, Christian.
