| 15:46:32 | dvo-plv | sean-k-mooney, Hello | |
| 15:46:54 | sean-k-mooney | dvo-plv: o/ | |
| 15:47:11 | dvo-plv | I would like to discuss out blueprint regarding NT NIC support. But it too late today, can we talk tomorrow? | |
| 15:47:34 | dvo-plv | when it will be comfortable for you ? | |
| 15:51:05 | sean-k-mooney | honestly i need to reload context. | |
| 15:51:36 | sean-k-mooney | so we can chat during the week but im not sure when ill be free. ping me durnign the week when your around | |
| 16:23:49 | dansmith | sean-k-mooney: I'm calling it a followup to the original BP, which is why I tagged it as such | |
| 16:40:20 | sean-k-mooney | ack | |
| 16:41:10 | sean-k-mooney | i didnt sleep great last night so i may not get to it today but if i dont ill review them tommorow if someone else does not review them in the interim | |
| 16:41:42 | dansmith | no rush | |

| 07:13:47 | hamidlotfi_ | Hi there, | |
| 07:13:47 | hamidlotfi_ | In the nova database, I see much `LOCK WAIT` on the `neutron.ports` table | |
| 07:13:47 | hamidlotfi_ | and I putting a sample log for the lock wait | |
| 07:13:47 | hamidlotfi_ | I want to know if is this a bug in the structure of a table or the script of the update or the user mistake. | |

| 09:54:27 | hamidlotfi_ | @dansmith @bauzas @sahid_ | |
| 10:22:41 | dvo-plv | sean-k-mooney, Are you here ? | |
| 10:44:28 | sean-k-mooney | dvo-plv: o/ | |
| 10:45:13 | dvo-plv | I wouldl iek to talk with you regarding out blueprint nt nic support, if you have free time for it | |
| 10:45:46 | dvo-plv | previously we decided that we will try to pass socket name with ovs command for dpdk port type | |
| 10:47:09 | sean-k-mooney | yes and i ask can we pass the name to ovs when addign the port so that we didn not have to compute one that matched the nic driver format | |
| 10:47:45 | sean-k-mooney | we also discussed that some of the magic constant are actully discoverable form sysfs like the vf offset | |
| 10:48:13 | dvo-plv | yes | |
| 10:49:19 | dvo-plv | we spent some time on the investigation and this is not possible to do it for dpdk port type with ovs. there will be alot of changes, DPDK community will not approve it | |
| 10:49:57 | sean-k-mooney | thats not ideal | |
| 10:50:23 | dvo-plv | So I would like to get back to the separate os-vif plugin | |
| 10:50:45 | dvo-plv | what do you think about that ? | |
| 10:50:50 | sean-k-mooney | not nessiarly what that means is that nova needs to tell neutron the vf specific info | |
| 10:51:20 | sean-k-mooney | so we need to pass info to the ml2 driver in the binding_profile | |
| 10:51:52 | sean-k-mooney | neutron can then use that to generate the socket path. alternitivly we could jsut generate the path ourselve in nova | |
| 10:52:21 | dvo-plv | path is not a problem, specific socket name is the root cause | |
| 10:52:44 | sean-k-mooney | the socket name is path of the path :) | |
| 10:52:47 | sean-k-mooney | but yes | |
| 10:54:51 | dvo-plv | So, we can somehow use port binding profile for this purposes? | |
| 10:56:17 | sean-k-mooney | yes that is what its for to pass info form nova to the network backend | |
| 10:56:27 | sean-k-mooney | we normally sotre the pci_adress in it | |
| 10:56:44 | sean-k-mooney | but we can have other fields like the offset ectra | |
| 10:56:59 | sean-k-mooney | or we can just comppute the socket name and pass that | |
| 10:57:07 | sean-k-mooney | which is proably the better option | |
| 10:57:30 | sean-k-mooney | since nova does not have the base path (neutron/ovs does have that info) | |
| 10:57:53 | sean-k-mooney | so we can provide the socket name in the binding profile and neutron can append that to the base socket path | |
| 10:58:03 | sean-k-mooney | and then we will get the full path back which we can store in the xml | |
| 11:00:20 | dvo-plv | okay, i see. but i have a question how we should handle pci. for socket name stdvio10, we need to use pci 0000:65:01.2. So we need vendor specific mechanism for parse socket name | |
| 11:00:41 | sean-k-mooney | its the other way around | |
| 11:00:49 | sean-k-mooney | we are selecting VFs in the pci tracker | |
| 11:01:01 | sean-k-mooney | and you need to compute the socket name from the adress | |
| 11:01:45 | sean-k-mooney | the main issue i think is still the multi device support | |
| 11:02:07 | sean-k-mooney | since the previous algorthim did not support more hten one nic | |
| 11:03:17 | dvo-plv | yes, currently we do not support multinic setup | |
| 11:03:44 | sean-k-mooney | right so i dont think we should support this in nova until that is addressed | |
| 11:04:57 | dvo-plv | Honestly, i forget about that, I will investigate internal if we have some plan how this should be done in the future, because as far as I know we have plan to provide this feature | |
| 11:06:02 | dvo-plv | But if this is a limitation for be in the common code, what about to pass us with separate os-vif plugin, which will handle all this issuses ? | |
| 11:06:57 | sean-k-mooney | a out of tree os-vif plugin will also reqiure your own ml2 driver in neutron | |
| 11:08:17 | dvo-plv | yes, we can implement it too, like Agilio https://github.com/Netronome/agilio-ovs-openstack-plugin/tree/master/vif_plug_agilio_ovs | |
| 13:57:13 | opendevreview | Dan Smith proposed openstack/nova master: WIP: Compile mdev samples for nova-next https://review.opendev.org/c/openstack/nova/+/897708 | |
| 13:58:11 | dansmith | bauzas: this is getting close to working ^ | |
| 13:58:29 | bauzas | dansmith: wow, thanks | |
| 14:00:36 | dansmith | last round only failed because I didn't sudo something | |
| 14:01:48 | sean-k-mooney | dansmith: would you mind in a followup allowing us to enabel other moduels | |
| 14:02:11 | sean-k-mooney | i.e. mdpy or mbochs? | |
| 14:02:13 | dansmith | sean-k-mooney: yeah I was going to do all the samples, I just wanted to get the mechanics working | |
| 14:02:32 | dansmith | or do you mean *any* other module? | |
| 14:03:05 | sean-k-mooney | i was thinking of makign CONFIG_SAMPLE_VFIO_MDEV_MTTY=m | |
| 14:03:11 | sean-k-mooney | a list | |
| 14:03:20 | sean-k-mooney | but mainly jsut the mtty samples | |
| 14:04:08 | sean-k-mooney | it might be nice if the set of flags to enable in the kernel config was just a var you could set in the local.conf | |
| 14:04:24 | sean-k-mooney | although | |
| 14:04:28 | sean-k-mooney | looking at it again | |
| 14:04:30 | dansmith | it's not that easy | |
| 14:04:36 | sean-k-mooney | you alls need to call make per module | |
| 14:04:44 | sean-k-mooney | so ya never mind | |
| 14:04:55 | dansmith | unless you want to build the whole kernel, you need to know configs and target module files, and the deps | |
| 14:05:01 | bauzas | fwiw, this will actually depend on what we can do with live-migration :) | |
| 14:05:10 | dansmith | but yeah, I'll extend this to do all the mdev samples | |
| 14:05:13 | sean-k-mooney | dansmith: ya lets keep it simple | |
| 14:05:13 | bauzas | if that's done per mtty, cool | |
| 14:05:18 | dansmith | bauzas: oh I know, but we could also apply a patch here | |
| 14:05:35 | bauzas | yeah, let's just start this simple with mtty | |
| 14:05:47 | sean-k-mooney | bauzas: so this is useful even without live migration | |
| 14:05:57 | bauzas | yup, definitely | |
| 14:06:09 | sean-k-mooney | it woudl be a majory win just to get any coverage of mdevs | |
| 14:06:59 | sean-k-mooney | so ya we can add follow up patches to do the nova config generation to enabel them | |
| 14:07:10 | sean-k-mooney | but that would be good to do in the devstack plugin to | |
| 14:07:47 | dansmith | yeah, point me at what I need to do config-wise | |
| 14:07:58 | sean-k-mooney | you technnially dont need that since we can just shove config snipit into config via local.conf | |
| 14:08:28 | dansmith | ack, but if it can do something for each sample it finds or something... | |
