| zhipeng | glad we finally managed to land lots of patches last week | 15:09 |
| zhipeng | let's comb through the ones we have | 15:09 |
| zhipeng | #info FPGA data modeling | 15:10 |
| zhipeng | #link https://review.openstack.org/526559 | 15:10 |
| Li_Liu | I have just submitted a patch for zhuli's comments | 15:10 |
| zhipeng | zhuli have you reviewed the updated patch ? | 15:10 |
| zhuli | reviewing now | 15:11 |
| zhipeng | other than zhuli's comment, any other concerns about this spec ? | 15:11 |
| *** Dutch has joined #openstack-cyborg | 15:14 | |
| zhipeng | if there are no other concerns, we should land this spec today | 15:15 |
| zhipeng | #action landing fpga data modeling spec today | 15:15 |
| zhipeng | #info zhuli's api/db patch | 15:15 |
| zhipeng | #link https://review.openstack.org/527396 | 15:15 |
| zhipeng | jkilpatr crushil could either of you guys give a workflow +1 for this patch ? | 15:16 |
| zhipeng | crushil_ | 15:16 |
| jkilpatr | I'm still confused, the tox command should run linters but not actual test code. | 15:17 |
| jkilpatr | unless the tox.ini is setup to run actual test code in the linter categories which I don't think it is | 15:17 |
| zhuli | liliu, you mean the attributes are constant which will be initialized with deployable object together and do not need further methods to modify? | 15:18 |
| zhipeng | Li_Liu per zhuli's question ? | 15:21 |
| zhipeng | zhuli could you take a look at jkilpatr's problem ? | 15:22 |
| Li_Liu | Zhuli, yes, that's what I meant | 15:22 |
| Li_Liu | the attributes table should be transparent to users | 15:24 |
| zhuli | jkilpatr, tox can support both linters check and unit test according to your command, for instance 'tox -epep8' for linters and 'tox -epy27' for unittest | 15:25 |
| zhuli | the openstack-tox-pep8 and openstack-tox-py27 gerrit jobs run against these two situation | 15:27 |
| jkilpatr | ok there we go I'll wf it | 15:28 |
| jkilpatr | unless crushil_ has objections? | 15:29 |
| zhuli | jkilpatr, you can see the detail in these links | 15:31 |

| zhipeng_ | crushil_ any ETA on a full implementation ready for review and landing ? | 15:34 |

| Li_Liu | Thanks a lot Zhuli | 15:35 |
| crushil_ | zhipeng_, It's almost ready. Need to write accompanying unit tests | 15:35 |

| jkilpatr | or zhuli's patch? | 15:38 |
| zhipeng_ | zhuli's | 15:38 |
| jkilpatr | I'll look at it | 15:39 |
| zhipeng_ | something like adding a report.py from nova-compute to cyborg-conductor | 15:39 |
| zhipeng_ | with the corresponding modifications | 15:39 |

| zhipeng | So I'm glad to have Dutch from Xilinx to join our dev team | 15:45 |
| zhipeng | Dutch the floor is yours sir | 15:45 |
| zhuli | dutch welcome | 15:46 |
| Dutch | Thanks! Hey everyone, I work with the Xilinx SDAccel team on our cloud program. I can help provide any resources or support from Xilinx. Also can help with SDAccel framework in general | 15:47 |
| Dutch | We are still coming up to speed on the Cyborg project but the project looks great and we are happy to get involved | 15:48 |
| zhipeng | Dutch could you provide some info on SDAccel ? | 15:49 |
| Dutch | Sure, SDAccel is basically the framework for PCIe attached Xilinx FPGAs. Currently we use two PFs. PF0 is user space for DMA and PF1 is management for ioctls | 15:50 |
| Dutch | Are people familiar with the driver at all? | 15:52 |
| zhipeng | I think you could give a quick overview :P | 15:52 |
| Dutch | Haha, I can't say I have done it over IRC before, this is usually consumed in slides with lots of images | 15:52 |
| Dutch | Also, caution, I am not on the drivers team, so there are times when I don't know all the details | 15:53 |
| zhipeng | haha i know | 15:53 |
| zhipeng | maybe you could drop a link here ? | 15:53 |
| zhipeng | for a good overview slide ? | 15:54 |
| Dutch | Sure #link https://www.xilinx.com/html_docs/xilinx2017_4/sdaccel_doc/index.html | 15:54 |
| zhuli | thanks, that's very helpful | 15:54 |
| Dutch | These are most of the user guides in one place instead of dealing with the PDFs, contents are the same | 15:55 |
| zhipeng | gr8t thx! | 15:55 |
| zhipeng | are there any support yet in the OpenStack for SDAccel ? | 15:55 |
| zhipeng | for example nova driver ? | 15:55 |
| Dutch | There is also a helpful platform guide UG1164, this is still a PDF | 15:56 |
| Dutch | #link https://www.xilinx.com/support/documentation/sw_manuals/xilinx2017_4/ug1164-sdaccel-platform-development.pdf | 15:56 |
| NokMikeR | are there any xilinx parts with an open bitstream? (and tools to program them)? | 15:57 |
| Dutch | Still no nova support, our openstack cluster is using pass-through, which as you can image is a serious limitation | 15:57 |
| Dutch | The drivers could be open, but bitstream generation is IP so unlikely we will ever see that open | 15:59 |
| Dutch | NokMikeR, what in particular do you want open? | 16:00 |
| NokMikeR | any way to program the device via e.g an arm cpu so the synthesis and routing is done on the board - that way the entry level for the programmer is lower. | 16:00 |
| Dutch | For drivers and runtime, absolutely. For synthesis and P&R, I am less sure. | 16:03 |
| Dutch | I am also not sure what "done on the board" means | 16:04 |
| NokMikeR | pcie board with fpga + additional cpu to generate the bitstream. you send that vhdl/verilog, "other code" and it all magically works :) | 16:04 |
| NokMikeR | self contained basically. no reliance on vivado etc. | 16:05 |
| NokMikeR | anyhow we are offtopic here, so Howard please carry on :) | 16:06 |
| zhipeng | no this is actually an interesting topic :P | 16:06 |
| Dutch | It is nice to think about but yeah, I would say that is a ways off | 16:06 |
| zhipeng | NokMikeR I know there are open source bitstream FPGA cards, but not sure if it is production level | 16:07 |
| Dutch | It might be possible to run Vivado on the add-in-card but as far as Vivado being open that seems very unlikely | 16:07 |
| Dutch | I would push the currently open project to do something like this | 16:08 |
| zhipeng | Dutch so coming back to SDAccel, the software defined here refering to ? | 16:08 |
| Dutch | SDAccell was initially built to support OpenCL memory model, and there is also support for OpenCL kernel code | 16:09 |
| Dutch | but it has advanced some to support iteration of HLS C and RTL IP | 16:09 |
| zhipeng | got it | 16:10 |
| Dutch | It was designed to be flexible so that it would support future models, MPI for example | 16:10 |
| zhipeng | folks thx very much for the gr8t discussion today, i'm afraid I have to close the meeting now | 16:11 |
| zhipeng | please go help reviewing the patch or drafting one, we have two weeks left before Queens code freeze | 16:11 |
| zhipeng | so let's squeeze in as many stuff as we could :) | 16:12 |
| NokMikeR | was the devstack bug report about the permissions for cyborg solved? | 16:12 |
| zhipeng | yes NokMikeR | 16:13 |
| NokMikeR | Great :) | 16:13 |

| guhcampos | Hi folks, a quick question: I may need to implement our driver for cyborg. Is there a way to write it as a plugin? Like a separate python package that can be installed alongside cyborg? Or do I have to add it to cyborg's tree alongside the generic driver? | 17:51 |
| crushil_ | guhcampos, Add it to Cyborg's tree alongside the generic driver | 17:54 |
| guhcampos | crushil_, thanks. I needed this confirmation to pressure management to sign the contributor agreement | 17:55 |
