| 03:55:12 | Sundar | @all: Please look at https://git.openstack.org/cgit/openstack/nova-specs/tree/specs/stein/approved/numa-topology-with-rps.rst?h=refs/changes/24/552924/14#n163 | |
| 03:55:28 | Coco_gao | shaohe_feng, that will be ok if name change, the conductor will delete the old device with name1 and add new device to db with name2. But actually, the db is exactly the same with the real situation. | |
| 03:55:43 | Li_Liu | Since it's pretty late for me here. Let's close it up and discuss more detail in tomorrow's sync up | |
| 03:56:05 | shaohe_feng_ | Li_Liu: OK. | |
| 03:56:33 | Coco_gao | but that name change for one device is not supposed to be frequent. | |
| 03:56:50 | shaohe_feng_ | Coco_gao: yes. not frequently. | |
| 03:57:17 | shaohe_feng_ | seldom resize the baremetal | |
| 03:59:41 | Li_Liu | Alright, let's call the meeting for today. Have a good night/day where ever you are | |

| 15:05:40 | wangzhh | Fine. | |
| 15:06:03 | xinranwang | Hi all | |
| 15:06:07 | wangzhh | Hi xinran. | |

| 15:06:35 | xinranwang | hi shaohe_feng_ wangzhh | |
| 15:06:53 | shaohe_feng_ | we have not hold this meeting for a long time. | |
| 15:07:24 | shaohe_feng_ | #link https://wiki.openstack.org/wiki/Meetings/CyborgDriverTeamMeeting#Agenda_for_next_meeting_:_Mar_18th.2C_2019 | |
| 15:07:28 | shaohe_feng_ | here is the agent. | |
| 15:07:50 | shaohe_feng_ | s/agent/agenda | |
| 15:07:57 | Li_Liu | Hi Gyus | |
| 15:08:04 | wangzhh | Hi, uncle Li. | |
| 15:08:16 | shaohe_feng_ | Li_Liu: morning uncle Li. | |
| 15:08:19 | Li_Liu | Hi, xiaohei~~ | |
| 15:08:28 | Li_Liu | hi shaohe | |
| 15:08:38 | shaohe_feng_ | I want to introduce some some hardware accelerators. | |
| 15:08:38 | Li_Liu | you guys wanna do a zoom meeting instead? | |
| 15:09:10 | shaohe_feng_ | 1. the current know type of accelerator card | |
| 15:09:45 | shaohe_feng_ | as we all know cyborg will support mdev and pci card. | |
| 15:10:11 | shaohe_feng_ | but now I find there are 2 other kinds of hardware card we can support. | |
| 15:10:35 | shaohe_feng_ | one is ip over PCIE, another is USB. | |
| 15:10:47 | Li_Liu | i see | |
| 15:11:06 | shaohe_feng_ | wangzhh: do you know these two kind cards? | |
| 15:11:08 | Li_Liu | can they fit into our current design? | |
| 15:11:29 | shaohe_feng_ | not sure, so we need more discuss with them. | |
| 15:11:56 | wangzhh | I don't know much about ip over pcie, what does that mean? | |
| 15:12:29 | Li_Liu | I think it's a remote case | |
| 15:12:55 | Li_Liu | PCI over ethernet? | |
| 15:13:14 | shaohe_feng_ | Li_Liu: yes. | |
| 15:13:43 | shaohe_feng_ | #link https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/vca-2-visual-compute-accelerator-product-brief.pdf | |
| 15:13:53 | shaohe_feng_ | Li_Liu: No, IP over pci. | |
| 15:14:05 | Li_Liu | from Operation System point of view, it's still a pci device right? | |
| 15:14:45 | shaohe_feng_ | Li_Liu: is it s pci devices, but you communicate with it by it. | |
| 15:14:52 | shaohe_feng_ | Li_Liu: it is a local pci card. | |
| 15:15:16 | shaohe_feng_ | such as the vca2 card, see link above, | |
| 15:15:34 | Li_Liu | you mean other hosts can communicate with it over ethernet? | |
| 15:16:29 | wangzhh | So, actually, it is a pci device? | |
| 15:16:31 | shaohe_feng_ | oh, the local host communicate the local card, over PCIE. | |
| 15:16:49 | wangzhh | from os view. | |
| 15:17:50 | shaohe_feng_ | wangzhh: from the os view, you can see it a new kind device with new driver maybe. | |
| 15:18:18 | shaohe_feng_ | there's another card I have attend meeting last week, seem this is a common way for some card. | |
| 15:18:58 | shaohe_feng_ | we can dig more about this kind of card. | |
| 15:19:52 | shaohe_feng_ | for usb card, the movidius AI card is this kind. | |
| 15:20:10 | Li_Liu | I think we just need to make sure 2 things: 1. can os-acc attach it like all the other devices, 2. can the resource fit into our current data model | |
| 15:20:53 | shaohe_feng_ | yes. | |
| 15:20:55 | Li_Liu | as long as these two requirements can meet, we should be good | |
| 15:21:26 | wangzhh | It make sense. | |
| 15:21:48 | shaohe_feng_ | I think the usb devices can satisfy these two requirements. | |
| 15:22:01 | Li_Liu | shaohe_feng_ have they finalize the resource structure yet? | |
| 15:23:10 | shaohe_feng_ | Li_Liu: usb, yes. | |
| 15:23:31 | wangzhh | How about another one? | |
| 15:23:31 | shaohe_feng_ | just remind these 2 kind devices. | |
| 15:24:20 | shaohe_feng_ | wangzhh: I'm not looking into looking into it well. | |
| 15:24:35 | shaohe_feng_ | OK, let's go ahead. | |
| 15:24:48 | wangzhh | OK. | |
| 15:24:52 | shaohe_feng_ | Re-enumeration of hardware card | |
| 15:25:17 | shaohe_feng_ | most of us know the issue of Re-enumeration. | |
| 15:25:52 | Li_Liu | the issue we discussed last week? | |
| 15:26:16 | shaohe_feng_ | no, but this is a common issue. | |
| 15:26:43 | shaohe_feng_ | the bus of a hardware card maybe change after we resize a hardware and reboot. | |
| 15:27:12 | shaohe_feng_ | seem this is a big problem for accelerator manage in cyborg. | |
| 15:28:01 | shaohe_feng_ | I have discuss it with Yongli, the main PCI devices contributor in nova. | |
| 15:28:29 | shaohe_feng_ | he say, nova does not allow resize hardware | |
| 15:29:35 | Li_Liu | you mean add/remove device after reboot? | |
| 15:29:54 | shaohe_feng_ | yes | |
| 15:30:04 | shaohe_feng_ | unless evict all VMs from this node. | |
