| #openstack-cyborg - 2018-01-17 | |||
| 15:38:51 | zhipeng_ | zhuli's | |
| 15:39:17 | jkilpatr | I'll look at it | |
| 15:39:31 | zhipeng_ | something like adding a report.py from nova-compute to cyborg-conductor | |
| 15:39:42 | zhipeng_ | with the corresponding modifications | |
| 15:40:45 | zhipeng_ | #action jkilpatr to start working on the cyborg-conductor report function | |
| 15:41:13 | zhipeng_ | Vipparthy the above mentioned code is about the cyborg-nova integration | |
| 15:41:27 | zhipeng_ | Dutch dude are you still around ? | |
| 15:43:58 | zhipeng_ | $topic Xilinx SDAccel introduction | |
| 15:44:07 | zhipeng_ | #topic Xilinx SDAccel introduction | |
| 15:45:29 | zhipeng | #topic Xilinx SDAccel introduction | |
| 15:45:50 | zhipeng | So I'm glad to have Dutch from Xilinx to join our dev team | |
| 15:45:58 | zhipeng | Dutch the floor is yours sir | |
| 15:46:30 | zhuli | dutch welcome | |
| 15:47:20 | 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 | |
| 15:48:10 | Dutch | We are still coming up to speed on the Cyborg project but the project looks great and we are happy to get involved | |
| 15:49:54 | zhipeng | Dutch could you provide some info on SDAccel ? | |
| 15:50:37 | 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 | |
| 15:52:02 | Dutch | Are people familiar with the driver at all? | |
| 15:52:17 | zhipeng | I think you could give a quick overview :P | |
| 15:52:52 | Dutch | Haha, I can't say I have done it over IRC before, this is usually consumed in slides with lots of images | |
| 15:53:39 | Dutch | Also, caution, I am not on the drivers team, so there are times when I don't know all the details | |
| 15:53:42 | zhipeng | haha i know | |
| 15:53:55 | zhipeng | maybe you could drop a link here ? | |
| 15:54:01 | zhipeng | for a good overview slide ? | |
| 15:54:29 | Dutch | Sure #link https://www.xilinx.com/html_docs/xilinx2017_4/sdaccel_doc/index.html | |
| 15:54:37 | zhuli | thanks, that's very helpful | |
| 15:55:20 | Dutch | These are most of the user guides in one place instead of dealing with the PDFs, contents are the same | |
| 15:55:21 | zhipeng | gr8t thx! | |
| 15:55:40 | zhipeng | are there any support yet in the OpenStack for SDAccel ? | |
| 15:55:46 | zhipeng | for example nova driver ? | |
| 15:56:41 | Dutch | There is also a helpful platform guide UG1164, this is still a PDF | |
| 15:56:47 | Dutch | #link https://www.xilinx.com/support/documentation/sw_manuals/xilinx2017_4/ug1164-sdaccel-platform-development.pdf | |
| 15:57:11 | NokMikeR | are there any xilinx parts with an open bitstream? (and tools to program them)? | |
| 15:57:33 | Dutch | Still no nova support, our openstack cluster is using pass-through, which as you can image is a serious limitation | |
| 15:59:08 | Dutch | The drivers could be open, but bitstream generation is IP so unlikely we will ever see that open | |
| 16:00:00 | Dutch | NokMikeR, what in particular do you want open? | |
| 16:00:40 | 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. | |
| 16:03:13 | Dutch | For drivers and runtime, absolutely. For synthesis and P&R, I am less sure. | |
| 16:04:01 | Dutch | I am also not sure what "done on the board" means | |
| 16:04:59 | NokMikeR | pcie board with fpga + additional cpu to generate the bitstream. you send that vhdl/verilog, "other code" and it all magically works :) | |
| 16:05:34 | NokMikeR | self contained basically. no reliance on vivado etc. | |
| 16:06:10 | NokMikeR | anyhow we are offtopic here, so Howard please carry on :) | |
| 16:06:26 | zhipeng | no this is actually an interesting topic :P | |
| 16:06:27 | Dutch | It is nice to think about but yeah, I would say that is a ways off | |
| 16:07:25 | zhipeng | NokMikeR I know there are open source bitstream FPGA cards, but not sure if it is production level | |
| 16:07:46 | Dutch | It might be possible to run Vivado on the add-in-card but as far as Vivado being open that seems very unlikely | |
| 16:08:03 | Dutch | I would push the currently open project to do something like this | |
| 16:08:25 | zhipeng | Dutch so coming back to SDAccel, the software defined here refering to ? | |
| 16:09:25 | Dutch | SDAccell was initially built to support OpenCL memory model, and there is also support for OpenCL kernel code | |
| 16:09:49 | Dutch | but it has advanced some to support iteration of HLS C and RTL IP | |
| 16:10:21 | zhipeng | got it | |
| 16:10:38 | Dutch | It was designed to be flexible so that it would support future models, MPI for example | |
| 16:11:10 | zhipeng | folks thx very much for the gr8t discussion today, i'm afraid I have to close the meeting now | |
| 16:11:45 | zhipeng | please go help reviewing the patch or drafting one, we have two weeks left before Queens code freeze | |
| 16:12:05 | zhipeng | so let's squeeze in as many stuff as we could :) | |
| 16:12:33 | NokMikeR | was the devstack bug report about the permissions for cyborg solved? | |
| 16:13:14 | zhipeng | yes NokMikeR | |
| 16:13:22 | NokMikeR | Great :) | |
| 16:14:09 | zhipeng | okey meeting adjourned | |

| 16:15:12 | Dutch | Thanks! | |
| 17:51:07 | 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? | |
| 17:54:46 | crushil_ | guhcampos, Add it to Cyborg's tree alongside the generic driver | |
| 17:55:28 | guhcampos | crushil_, thanks. I needed this confirmation to pressure management to sign the contributor agreement | |
