<div dir="ltr">As a dirty hack i'd suggest you searching for a patch that were posted some time ago, that enables DEV_ID spoofing. It was used to "quadrify" nvidia GPUs. I think i've last seen this patch on the arch forums, and it's not upstream since it was experimental.<br></div><div class="gmail_extra"><br><div class="gmail_quote">2015-08-22 12:36 GMT+03:00 ehsan davoodi <span dir="ltr"><<a href="mailto:e.davoodi@gmail.com" target="_blank">e.davoodi@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div>asus n56jk<br></div>vt-d support motherboard(bios) and cpu i7-4710HQ <br></div>recent laptop does not have pci express card slot<br></div>I just want to passthrough subsystem id too of pci<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Aug 21, 2015 at 6:19 PM, Bradley Davis <span dir="ltr"><<a href="mailto:bradleydavisjr@gmail.com" target="_blank">bradleydavisjr@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>What laptop make and model is it? If it doesn't support it now, chances are it wont due to a technical limitation. I was able to get PCI passthrough working in a HP Elitebook of mine by passing through the Express Card to the VM. I was only doing a USB express card. If you wanted to do VGA, you could create yourself an express card to pcie slot with powersupply.
