</div>Okay PCI IDs might seem useful but we have a lot of situations where<br>
they aren't available,<br></blockquote><div><br></div><div>I was thinking the same, but then noticed that it's an int, and a pci device or vendor id is 16 bit, so you could implement this by returning the pciid if you have it, or something > 0xFFFF if you don't have it (and sort of make sure that those don't overlap).</div>

a) ARM devices generally don't have them<br>
b) nvidia generally espouse using PCI IDs in favour of a chip family<br>
ID they bake into the GPUs,<br>
nouveau doesn't even know the actual PCI IDs in userspace, we could<br>
find them but it does take a bit more work, like new kernel interface.<br>

</div>Any reason for the value to be different here? Like a use case?<br>
<div class="im">> + 14) Why not make the queries from issue #14 GL functions (instead of GLX)?<br>

</div>from issue 14? this is issue 14<br>
