Actually that comment as well as the name "writeback" is a bit outdated.
IIRC we also use the 32bit and 64bit addresses allocated with
amdgpu_wb_get for the wptr polling addresses.
In other words the GPU polls from the address and the CPU writes to them.
I wouldn't change the name, but noting that in the comment might be a
good idea.
Anyway the patch is Reviewed-by: Christian König <christian.koenig@amd.com>.
Regards,
Christian.
