[amd-gfx] golden registers for CIK devices

[StDenis, Tom]

Hi Christian,


Ah thanks.  In that case nothing trivial pops out.  Our init/start functions are not verbatim copies of one another.

Keep in mind that radeon uses byte addresses for register offset while amdgpu uses dword addresses.

So the different values are correct and intentional.

Another thing I noticed is that in the ring test on amdgpu side we write a different value into the buffer, e.g.


-       amdgpu_ring_write(ring, (scratch - PACKET3_SET_UCONFIG_REG_START));
+       amdgpu_ring_write(ring, ((scratch - PACKET3_SET_UCONFIG_REG_START) >> 2));

So far I've tried keep/change golden registers to match radeon, change this ring value, and for kicks disabled CG.  The ring test still fails.  I was really hoping this would be a simple copy/paste error from the radeon side :-)

Hi team,


Is there a reason the golden registers have different register addresses on amdgpu's cik.c versus radeon's cik.c?


Thanks,

Tom
