We may simplify the logic as below.
How do you think?
list_del_init(&bo_va->base.vm_status);
unsigned mem_type = bo->tbo.mem.mem_type;
/* If the BO is not in its preferred location add it back to
* the evicted list so that it gets validated again on the
* next command submission.
*/
if ((bo && bo->tbo.resv == vm->root.base.bo->tbo.resv) &&
(!(bo->preferred_domains &
amdgpu_mem_type_to_domain(mem_type))))
list_add_tail(&bo_va->base.vm_status, &vm->evicted);
Looks good, but I already pushed that patch just now. if you like, you
can make a simplify patch with your idea.
