<div class="WordSection1">
<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">About bug of unable to create vm with GPU/Crypto passthrough devices<o:p></o:p></p>
<p class="MsoNormal"><a href="https://bugs.launchpad.net/starlingx/+bug/1824831">https://bugs.launchpad.net/starlingx/+bug/1824831</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The question is clear now for GPU passthrough.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">According to openstack doc, we need to modify nova.conf to add alias info.<o:p></o:p></p>
<p class="MsoNormal"><a href="https://docs.openstack.org/nova/pike/admin/pci-passthrough.html">https://docs.openstack.org/nova/pike/admin/pci-passthrough.html</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For QAT, we have added some frequently used QAT items by hardcoding, like below<o:p></o:p></p>
<p class="MsoNormal">alias = {"vendor_id": "8086", "product_id": "0435", "name": "qat-dh895xcc-pf"}<o:p></o:p></p>
<p class="MsoNormal">alias = {"vendor_id": "8086", "product_id": "0443", "name": "qat-dh895xcc-vf"}<o:p></o:p></p>
<p class="MsoNormal">alias = {"vendor_id": "8086", "product_id": "37c8", "name": "qat-c62x-pf"}<o:p></o:p></p>
<p class="MsoNormal">alias = {"vendor_id": "8086", "product_id": "37c9", "name": "qat-c62x-vf"}<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can we do it the same for GPU. Add GPU items by hardcoding.<o:p></o:p></p>
<p class="MsoNormal">As I know, you used [102b:0522] [vendorid:productid]<o:p></o:p></p>
<p class="MsoNormal">I also saw below GPU product.<o:p></o:p></p>
<p class="MsoNormal">[1a03:2000]<o:p></o:p></p>
<p class="MsoNormal">[8086:3e92]<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">BTW, can we create port and attach it to VM, so that no need to add this alias.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Perfect solution is to detect gpu info automatically and add to alias list after power on.<o:p></o:p></p>
<p class="MsoNormal">From my point, this is new feature requirement <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any comment?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks<span lang="ZH-CN" style="font-family:SimSun">！</span><o:p></o:p></p>
<p class="MsoNormal">Zhipeng<o:p></o:p></p>
