| sf-slack | <kgugala> tcal: you need to have custom runners registered for the repo - those are registered for Symbiflow repo. To make it work in your fork you'd need to add a custom runner there | 06:18 |

| sf-slack | <pgielda> @tcal custom runners are used because some of the jobs require more resources (like disk space or RAM) than normal GA runners provide. | 10:22 |
| sf-slack | <pgielda> But @kgugala is right that they are only provided in the Symbiflow organization on github (more precisely, just in symbiflow-examples repo) | 10:22 |
| sf-slack | <pgielda> [those runners are, as you error suggest matvhe against a label "self-hosted"] | 10:24 |
| sf-slack | <pgielda> *match | 10:24 |
| sf-slack | <pgielda> If you open a PR to Symbiflow/symbiflow-examples, then your fork will be run in the Symbiflow org context and the runners should work fine | 10:25 |
| sf-slack | <pgielda> And judging from the https://github.com/SymbiFlow/symbiflow-examples/pull/121 everything worked fine. | 10:26 |

| lambda | litghost: https://github.com/SymbiFlow/symbiflow-examples/issues/120, FYI | 16:02 |
| litghost | I saw that, thanks! | 16:26 |
| Lofty | kgugala: I just fixed a segfault in scc; you'll probably want to pull the quicklogic-sta branch again | 16:27 |
| sf-slack | <kgugala> awesome | 16:28 |
| sf-slack | <kgugala> thanks | 16:29 |
| Lofty | I found it while looking at the bram testcase, actually | 16:29 |
| *** mkru has joined #symbiflow | 16:30 | |
| Lofty | Definitely need to think of more things to do though | 16:35 |
| LoneTech | well, seems I may have found my first stumbling block for adding Spartan 6 to project x-ray. Not a very worrying one, really. prjxray assumes 32-bit words in the bitstream, but spartan6 uses 16-bit. in addition, they're byte aligned in the file. | 16:42 |
| litghost | prjuray-tools might be a better starting place, as it was an attempt to generalize the 7-series tools for 6/7/US/US+ | 16:52 |
| litghost | In theory it supports all 4, but I only have confidence that it has been tested on 7/US/US+ | 16:52 |
| litghost | https://github.com/SymbiFlow/prjuray-tools | 16:53 |
| LoneTech | thanks | 17:09 |
| *** dnltz has joined #symbiflow | 17:14 | |
| LoneTech | looks very similar. still went uint32_t, added xcu and xcup series folders. | 17:17 |

| litghost | I don't believe so? | 17:20 |
| LoneTech | ah. found Architecture WordType. this has been started | 17:21 |
| LoneTech | I'm slowly getting oriented, bound to misunderstand things to degrees | 17:21 |
| *** gvb has quit IRC | 17:22 | |
| LoneTech | so it translates to/from 32 bit internally through BigEndianSpan and out_bitstream_writer | 17:24 |
| *** kgugala has quit IRC | 17:25 | |
| *** mkru has quit IRC | 17:28 | |
| LoneTech | so what bitread is doing is trying to read past end of file through absl::span and not catching the out of range exception | 17:34 |
| litghost | Sounds like a bug! | 17:35 |
| LoneTech | definitely | 17:36 |
| LoneTech | but what's the c++ way to fix it? as a poor Python programmer, I'm used to iterators that know when they end. | 17:36 |
| litghost | Is bitread using an mmap? | 17:37 |
| litghost | When the mmap was created, it used stat to determine the file length | 17:37 |
| LoneTech | it reports the file length before failing | 17:38 |
| litghost | Feel free to file an issue with a replicating test case. That makes it easier to answer questions | 17:38 |
| LoneTech | got it. big_endian_span::end is wrong | 17:43 |
| LoneTech | trying to fix | 17:44 |
| LoneTech | ... if indeed it's failing in the place I think :/ | 17:50 |
| LoneTech | why doesn't even a debug build in a debugger give a halfway usable backtrace? | 17:50 |
| *** gvb has joined #symbiflow | 17:52 | |
| litghost | Is it actually a debug build? | 17:52 |
| litghost | If you run "file <exe>" does it report that debug symbols are present? | 17:53 |
| *** gvb has quit IRC | 17:54 | |
| LoneTech | looks like not quite. it's unstripped, not debug symbols. gonna want to resolve that | 17:56 |
| LoneTech | huh. CMakeCache apparently overrode cmake command line for build type | 17:58 |
| LoneTech | better, pie with debug_info | 17:58 |
| litghost | Ya, whenever you don't get debugging symbols, use "file <x>" to ensure that debugging symbols are actually there | 18:00 |
| litghost | Because some builds like to strip out stuff, even in debug modes | 18:00 |
| LoneTech | much better | 18:00 |
| litghost | Yay | 18:00 |
| LoneTech | well this was silly. had to pass -architecture Spartan6 | 18:08 |
| LoneTech | now to build that part file it wants | 18:09 |
| litghost | Ya, that is true | 18:16 |

| nickoe | litghost: what do you think about https://github.com/SymbiFlow/symbiflow-arch-defs/pull/1972 ? Does it need more work? | 18:35 |
| nickoe | or are we still giving kgugala a change to re-review? | 18:35 |
| nickoe | ugh :D it seems you just merged it just now, 33 seconds ago | 18:36 |

| *** kgugala has joined #symbiflow | 18:38 | |
| sf-slack | <timo.callahan> @kgugala @pgielda thanks for the info about runners. I'll ignore the errors. Would it be easy to suppress the run when the runners aren't available? | 18:43 |
| *** dkozel has quit IRC | 18:43 | |
| sf-slack | <kgugala> it's GitHub who tries to start the run | 18:44 |
| sf-slack | <kgugala> and it does not provide an option to not start it if there is no runner available | 18:44 |
| sf-slack | <timo.callahan> Interesting. At least they fail immediately and don't waste resources. | 18:46 |
| sf-slack | <pgielda> its just that on your account (github.com/tcal-x) you are your own org ("tcal-x") and on your org there are no runners that match the set of tags ("self-hosted", "Linux", "X64") | 18:54 |
| sf-slack | <pgielda> github is not smart to figure out that maybe you forked but did not want to run things on your own org. I think in fact that its not smart that GitHub autoenables CIs on forks. but well... | 18:56 |

| nickoe | How can "symbiflow" be used in nmigen? I mean for an xilinx board use the fasm stuff insted of vivado? | 22:23 |
| litghost | Good question for kgugala. I believe that type of work has been started | 22:33 |
| nickoe | I tried to add the basys3 board to it but it fails to build, probably caused by some issye with the board definition, but it would be nice if I could easily add support for FOSS synth or whatever you call it, see https://github.com/nickoe/nmigen-boards/commit/c0807d845d2d3be3ae7c09ebc9cad80a12fdcbfb | 22:36 |
| nickoe | litghost: ^ | 22:36 |
| tcal | Good question I agree. I was going to say "Just dump Verilog out of nMigen, then feed that into Symbiflow (see SymbiFlow Examples)". But then I remembered that yosys can maybe read nMigen directly(?). And I kind of remember nmigen scripts having a --toolchain option. So I don't have any real answers and would like to know. Google turns up this: https://github.com/nmigen/nmigen/pull/463 . | 22:40 |
| nickoe | tcal: mm, thanks, but I am not sure how I can do that with the "python3 -m nmigen_boards.basys3" teset | 23:00 |
| nickoe | tcal: I guess this is what is meant? https://dpaste.com/8NSZJWXCK | 23:13 |
| tpb | Title: dpaste: 8NSZJWXCK (at dpaste.com) | 23:14 |
| nickoe | I am not sure what path it needs | 23:16 |
| nickoe | mmm, I made the vivado bitstream generation happy | 23:21 |
| nickoe | mmm | 23:21 |
| nickoe | and it blinks | 23:24 |
| nickoe | Ahh, I guess it wants https://github.com/nmigen/nmigen/blob/b466b724fe9f62140062afc9ecde9a920a261487/nmigen/vendor/xilinx_7series.py#L185-L192 but with the symbiflow-examples setuup the binaries are prefixed with symbiflow_ so they are not accepted in this case. :/ | 23:52 |
| litghost | I think we want back and added the symbiflow_ prefix to avoid name collision | 23:54 |
| litghost | And didn't update nmigen | 23:54 |
| litghost | We should add a directly nmigen example to symbiflow examples to catch that type of error | 23:55 |
