| 14:37:40 | jgilaber | thanks chandankumar I'll look again on Monday | |
| 14:37:44 | chandankumar | sure | |
| 14:38:05 | chandankumar | on pci-sim implementation side, I have 4k changes , It support nvme list on host as well as in guest | |
| 14:38:21 | chandankumar | it also support nvme sanitize and zero write I think | |
| 14:38:28 | chandankumar | I will push the changes on monday | |
| 14:39:19 | sean-k-mooney | ok we will need to review that carfully | |
| 14:39:22 | sean-k-mooney | but that is promising | |
| 14:39:40 | chandankumar | all vide coded | |
| 14:40:06 | chandankumar | but it works, I need to take a look at code and restructure it when I get time | |
| 14:40:38 | sean-k-mooney | yes, i did many roudn of selfe review and reinemnet befor ei push the first public verion for review ot try and get the kernel driver ot follow the upstream kernel convetions and make it robost put also protable | |
| 14:41:03 | sean-k-mooney | so there are two portablities target i have in mind currently | |
| 14:41:31 | sean-k-mooney | 1 i want to make it so the pci-sim cna work on ubutnu 2026.04, debian 13 and eventualy centos 10 stream kernel | |
| 14:41:53 | sean-k-mooney | the other portablity seam is it would be nice to make it work on x86_64 adn aarch64 in the future | |
| 14:42:02 | chandankumar | this is what I have https://paste.openstack.org/raw/bBpYnMalpXkMgsaitSKi/ | |
| 14:42:19 | sean-k-mooney | so we may need ot factor out some compaitbality code ectra to make that work | |
| 14:43:08 | sean-k-mooney | ya so Phase 2 — stock nvme driver binding via reserved-memory BAR0: | |
| 14:43:10 | sean-k-mooney | Uses boot-time reserved memory (memmap=SIZE$START) to back VF BAR0 | |
| 14:43:12 | sean-k-mooney | addresses with real RAM. | |
| 14:43:14 | sean-k-mooney | is somehtin i wanted to avoid | |
| 14:43:41 | sean-k-mooney | i really dint want to bring that across form the nvmevirt approch if we coudl avoid it | |
| 14:44:09 | chandankumar | but it is needed for showing nvme on host | |
| 14:44:18 | sean-k-mooney | not nessiarly | |
| 14:44:30 | chandankumar | I was not getting other idea so borrowed from nvmevirt | |
| 14:46:13 | sean-k-mooney | i belive we can allcoate a much smaller ammoutn fo memroy and then back the nvme deevice with files on disk | |
| 14:47:00 | sean-k-mooney | chandankumar: anyway push it for review when you think its ready for that | |
| 14:47:08 | sean-k-mooney | and we can dicuss that in more detail | |
| 14:47:54 | chandankumar | min memmap reservation: 112 KB of reserved physical RAM, one 16 KB NVMe BAR0 region per VF | |
| 14:48:10 | chandankumar | ok pushing | |
| 14:49:18 | sean-k-mooney | so the pci-sim today does not preacllotate resreved memory | |
| 14:49:35 | sean-k-mooney | it allcoates a small amount at runtime for the pci config space and minimal bars | |
| 14:50:19 | sean-k-mooney | i expect we shoudl be able ot do the same for the nvem emulation (basiclly the contole regeiseter and command/data queues) | |
| 14:50:35 | sean-k-mooney | but keep the data storate just as a raw file on disk | |
| 14:50:53 | sean-k-mooney | so we are not using ram for the nvme capscity jsut the hardware emulation | |
| 14:53:29 | sean-k-mooney | chandankumar: https://paste.opendev.org/show/bjZuArbpAxmE35uoUUoV/ was my design chat on this topic from a week or to ago | |
| 14:53:37 | sean-k-mooney | https://paste.opendev.org/show/bjZuArbpAxmE35uoUUoV/ | |
| 14:53:56 | sean-k-mooney | was the draft planing prom i was creating to help design this work | |
| 14:54:42 | opendevreview | chandan kumar proposed openstack/cyborg master: [WIP]pci-sim: add NVMe 1.4 controller emulation with host visibility https://review.opendev.org/c/openstack/cyborg/+/995079 | |
| 14:54:45 | sean-k-mooney | you will noteice that still reference https://github.com/SeanMooney/cyborg-extra/blob/master/pci-sim/fake_pci_sriov.c | |
| 14:54:53 | sean-k-mooney | since that was over a month ago | |
| 14:56:29 | sean-k-mooney | May 17, 12:20 AM | |
| 14:57:17 | chandankumar | ah thank you for sharing that , I will go over that | |
| 14:58:08 | sean-k-mooney | the paste was the final promt i had seelte on as the requriemet for the next plannign session to design the overall vf_personality feature | |
| 14:58:36 | sean-k-mooney | but i parked that work on until the intial pahse was merged and hook up into tempest testing as a phase 2 work | |
| 15:05:25 | chandankumar | ok | |
| 15:05:42 | chandankumar | see ya on monday, have a good weekend! | |

| 15:30:23 | chandankumar | sean-k-mooney: Hello, this time all the tests passed https://review.opendev.org/c/openstack/cyborg-tempest-plugin/+/995328 (with some modification), https://storage.gra.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_5ac/openstack/5ac2a8a4b85843cfa8aea0aa2a697a9c/testr_results.html | |
| 15:30:40 | chandankumar | in lsblk output nvme block is not there | |
| 15:30:43 | chandankumar | in the guest | |
| 15:34:49 | chandankumar | ah, I need to add memmap params for that, I need a baremetal job there it will work, but I can test that tomororw | |

| 16:12:14 | sean-k-mooney | ack ill try and take a look. however i would prefer if we did nto have a seperate job for the nvme work | |
| 16:12:45 | sean-k-mooney | so we might start that way but i woudl like to have a single job that test all 3 of pci,nvme and mdev drivers before teh end of the release | |

| 12:12:51 | chandankumar | sean-k-mooney: Hello, can you take a look at https://review.opendev.org/c/openstack/cyborg-tempest-plugin/+/992330 and https://review.opendev.org/c/openstack/cyborg-tempest-plugin/+/992328/ in your free time, not super urgent, thank you! | |
| 12:29:34 | sean-k-mooney | ill update https://review.opendev.org/c/openstack/cyborg-tempest-plugin/+/992330/3 a little later today | |
| 12:31:26 | sean-k-mooney | i would liek to merge the srbac serives this week assuming there are no outstandign issues. after that i plan ot adress teh ruff/per-commit changes next on the tempest plugin side but ill update https://review.opendev.org/c/openstack/cyborg-tempest-plugin/+/992347/1 to cover all ai agents first | |
| 12:32:20 | chandankumar | no all good from my side | |
| 12:32:30 | chandankumar | I will take a look at docs tomorrow | |
| 12:32:40 | sean-k-mooney | chandankumar: do you have any patch for teh tempest plugin you think woudl be good to land sooner rather then later? | |
| 12:33:27 | sean-k-mooney | i need to swap to spec review soon and hopefully we can move forward whith those today | |
| 12:33:37 | sean-k-mooney | so that next on my list | |
| 12:34:00 | chandankumar | sean-k-mooney: I think I can drop https://review.opendev.org/c/openstack/cyborg-tempest-plugin/+/992210 in favor of your pci scenario tests. | |
| 12:34:17 | chandankumar | No other patch from my side on cyborg-tempest-plugin | |
| 12:34:51 | sean-k-mooney | oh the placement ones | |
| 12:35:21 | sean-k-mooney | those are not nessisarly reduntance but they are also not actully secnairo tests in the normal sense | |
| 12:35:45 | chandankumar | yes, but it is alos more than api tests | |
| 12:36:19 | sean-k-mooney | ya so i think we done really need to have placement assert the provier toplogy | |
| 12:36:30 | sean-k-mooney | but its up to you. | |
| 12:36:39 | sean-k-mooney | they add soem addtion coverage but not a lot | |
| 12:36:44 | chandankumar | Ok I will fine that patch and move it to api test | |
| 12:37:15 | sean-k-mooney | have you tested those with the pci-sim? | |
| 12:37:23 | chandankumar | I tested it with pci-sim | |
| 12:37:59 | sean-k-mooney | ack so ya if you move them to api i think that woudl be fien. we could keep them in secario to as you said its somewhere in between | |
| 12:38:01 | chandankumar | sorry let me double check | |
