Hi Guys,

I just tried the patch out as positive flow tests (basically make sure umr 
commands still work before/after) on my gfx12 devel machine and I didn't notice 
any problems.  I've read through the patch and it looks good to me but I'm not

Right. The user copies under the locks come from

  566281595037 ("drm/amd/amdgpu: Add bank selection for MMIO debugfs (v3)")

  37df9560cd3e ("drm/amd/amdgpu: New debugfs interface for MMIO registers (v5)")

for amdgpu_regs2. I'll use those as the Fixes tags in v2, together with
your Acked-by, once Tom and Vitaly have had a look.

Thanks,
Mikhail
