The next in struct amdgpu_vm_bo_base is not a list_head, I'm not
sure whether we can use list_for_each_entry here.

Ah, of course. In this case feel free to go ahead.
BTW: What's the size of the structure now?

you mean struct amdgpu_vm_bo_base ? It only has few pointer and a list_head ,
should be pretty small .
struct amdgpu_vm_bo_base {
/* constant after initialization */
struct amdgpu_vm*vm;
struct amdgpu_bo*bo;
/* protected by bo being reserved */
struct amdgp
Yeah, that one is intentionally very small because it is used so often.
When it grows over the next power of two by this change we need to figure out a
different approach.

bool is_xgmi is added in bo_va structure , this change won't increase the size
of struct amdgpu_vm_bo_base. Anyway , can I said it's reviewed by you now?

Even the preferred_domains been changed for bo that original is none xgmi here
, it doesn't means driver must change the XGMI status for the bo_va. From
current design, only the bo later been added to the compute VM (through
bo_add) will be enable the XGMI mapping. Without that call , the XGMI

I think we only care about the context device (adev) and the real device
this bo been allocated(robj->tbo.bdev). The bo_va or base don't have
the device pointer directly, it have a pointer to bo which should be
the same as robj here. We can move the same_hive check out of the
loop .
