| 15:05:51 | Sundar | Shaohe: both models are possible. The main question is, is the developer/tenant ok with sharing his bitstreams with the cloud provider? If so, we can upload it to Glance first | |
| 15:05:53 | Li_Liu | yes, we can provide both capabilities depends on senario | |
| 15:06:16 | Li_Liu | use the 1st way when user owns the BM and entire FPGA | |
| 15:06:27 | Li_Liu | use 2nd way elsewhere | |
| 15:07:14 | Sundar | Li_Liu: Sure. One way is for the VM to invoke Cyborg REST API and target the region assigned to it. Another way is for the VM to have a connection to host e.g. virtio-serial. That way, the bitstream from the VM is not going through many network paths before coming back to the host | |
| 15:08:00 | Li_Liu | We did consider the virtio-serial way | |
| 15:08:07 | Sundar | It also requires less knowledge on the VM's part: it only sends the bitstream ID or the bitstream itself, and Cyborg will target the region assigned to the VM. The VM need not know which region is assigned to it | |
| 15:08:34 | Sundar | Li_Liu: Cool. What is your evaluation of virtio-serial? | |
| 15:08:43 | Li_Liu | but the problem is in order to control the access on who can program the FPGA, the host still need to contact Cyborg anyways | |
| 15:09:07 | Sundar | Well, the Cyborg agent on the host can listen to virtio-serial | |
| 15:09:24 | Li_Liu | so the flow becomes virtio-serial --> Host --> Rest Call --> Cyborg --> access check --> Host --> Program | |
| 15:09:26 | Sundar | May be it is multi-threaded, or has helper daemons, for scalability | |
| 15:10:01 | Sundar | We don;t need REST API in this 2nd flow. The request via virtio-serial is acted upon by the Cyborg agent | |
| 15:10:11 | Li_Liu | it does not save too much network access but make the flow rather complecated | |
| 15:10:52 | Li_Liu | But the Agent needs to download the bitstream from glance | |
| 15:11:07 | Sundar | Are you assuming that REST API is involved, even with virtio-serial? If not, it is a simple 1-hop without TCP/IP networking | |
| 15:11:13 | Li_Liu | and glance needs to check if this user can use this specific bitstream | |
| 15:11:44 | Li_Liu | I think is real use case, you can not avoid REST calls | |
| 15:11:56 | Li_Liu | This is a cloud environment after all | |
| 15:12:28 | Sundar | Li_Liu: true. Either the VM provides the bitstream, which is validated for authenticity/encryption in some way. Or, the VM request refers to a bitstream id in glance | |
| 15:13:12 | Sundar | Li_Liu: "you can not avoid REST calls" Why is that? For checking whether the tenant has privileges? | |
| 15:14:37 | Li_Liu | One of the methodologies is not to allow use send a bitstream to load directly | |
| 15:15:39 | Li_Liu | this is case, the bitstreams are either coming from Glance, or from a synthesis server | |
| 15:16:32 | Li_Liu | we don't want to allow the use send a unkown bitstream through virtio-serial and blindly A | |
| 15:16:40 | Li_Liu | load it to the FPGA | |
| 15:17:02 | Sundar | Oops, running late for my next meeting. Good discussion. :) I'll check back here as much as I can. | |
| 15:17:27 | Li_Liu | actully, I gotta run as well... I am still on vacation... | |
| 15:18:05 | Li_Liu | shaohe_feng, could you terminate the meeting and log the conversation, we can pick it up later | |
| 15:20:40 | shaohe_feng | OK. we can discuss more about it next time. | |
| 15:21:00 | shaohe_feng | #topic docs | |
| 15:21:13 | shaohe_feng | we need to improve cyborg docs. | |
| 15:21:44 | shaohe_feng | I have update the wiki https://wiki.openstack.org/wiki/Cyborg#How_to_contribute | |
| 15:21:48 | shaohe_feng | add DevStack Quick Start link to the wiki | |
| 15:21:55 | shaohe_feng | so New contributors can follow it setup their cyborg env. | |
| 15:22:00 | shaohe_feng | Any issue during the setup, they can fix it and feedback to community. | |
| 15:22:04 | Li_Liu | I will try to work on it with couple other folks in doc tesam | |
| 15:22:23 | shaohe_feng | Li_Liu, good, thanks. | |
| 15:22:41 | shaohe_feng | AoB? | |
| 15:23:48 | shaohe_feng | OK, let's end the meeting. | |

| 15:24:31 | shaohe_feng | bye. | |
| 15:26:38 | sum12 | i think start meeting was not considered as there was space before startmeeting :) | |
| 15:27:24 | Li_Liu | lol | |

| 14:06:21 | shaohe_feng | evening wangzhh | |
| 14:06:23 | tony | hi | |
| 14:06:35 | shaohe_feng | hello tony | |
| 14:06:58 | wangzhh | hello everyone | |
| 14:07:11 | tony | hello everyone | |
| 14:07:32 | Sundar_ | shaohe: Sure | |
| 14:08:12 | shaohe_feng | OK. let's start. | |
| 14:08:19 | Sundar_ | Hi Tony | |
| 14:08:26 | Sundar_ | Hi Wangzhh | |
| 14:08:29 | Guest4480 | Hi | |
| 14:08:31 | shaohe_feng | welcome tony | |
| 14:08:39 | shaohe_feng | #topic current status of drivers | |
| 14:09:16 | tony | ths shaohe | |
| 14:09:17 | shaohe_feng | I have list the tasks on the etherpad #link https://etherpad.openstack.org/p/cyborg-driver-tasks | |
| 14:09:53 | shaohe_feng | let go through the tasks | |
| 14:10:20 | shaohe_feng | wangzhh, are you going on the VGPU? | |
| 14:10:31 | wangzhh | OK. Let introduce my work. | |
| 14:10:50 | shaohe_feng | welcome. | |
| 14:11:08 | wangzhh | I'm going on the VGPU. | |
| 14:11:42 | wangzhh | And when I merged my code. I find some exist bug:( | |
| 14:12:12 | wangzhh | cyborg-agent doesn't work well. | |
| 14:12:35 | wangzhh | Such as https://review.openstack.org/#/c/572080/ | |
| 14:13:56 | wangzhh | So, before VGPU driver, maybe I should fix them first. | |
| 14:14:13 | shaohe_feng | good catch. | |
| 14:14:49 | shaohe_feng | so this is an urgent fix. | |
| 14:15:10 | xinran__ | Hi sorry for being late | |
| 14:15:21 | shaohe_feng | xinran__, evening. | |
| 14:15:50 | shaohe_feng | Li_liu is not on line. | |
| 14:16:11 | shaohe_feng | he introduce deployable object. | |
| 14:17:04 | shaohe_feng | Sundar_, and other developers, please help to review wangzhh bug fix | |
| 14:17:15 | shaohe_feng | #link https://review.openstack.org/#/c/572080/ | |
| 14:18:05 | shaohe_feng | wangzhh, other process on VGPU? can you help to update the task list? #link https://etherpad.openstack.org/p/cyborg-driver-tasks | |
| 14:19:12 | shaohe_feng | ^ wangzhh, update the status. | |
| 14:19:23 | shaohe_feng | OK, next. | |
| 14:19:29 | wangzhh | shaohe_feng: OK | |
| 14:19:46 | shaohe_feng | SPDK, Helloway are you on line? | |
| 14:20:38 | Helloway | yes | |
| 14:21:15 | shaohe_feng | so any process on the SPDK? | |
| 14:22:37 | Helloway | Temporarily no | |
| 14:24:38 | shaohe_feng | Helloway, can you help to update the SPDK status on the #link https://etherpad.openstack.org/p/cyborg-driver-tasks ？ | |
| 14:24:58 | shaohe_feng | OK, next provider report. | |
| 14:25:52 | shaohe_feng | Sundar_, Do we support multi-resource class and nest provider in this release | |
