From: Jiadong Zhu <jiadong....@amd.com>
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.
