      <div dir="ltr">Hello!
        <div>I was trying to figure out the impact of gpu page tables on
          applications' performance. I noticed that there are 16 vmids
          supported by the hardware <i>Vega 10</i>. Is it possible to
          use physical address directly in some vmids, or use physical
          address globally?</div>
      </div>

    No. VMID0 is used by the kernel for jobs like copying things from A
    to B and even there we use the VM remapping functionality.<br>
