| Ritish | lkcl, to confirm, am I at the right place: https://libre-soc.org/HDL_workflow/microwatt/ | 06:51 |
|---|---|---|
| Ritish | once the microwatt part is done, I think I can try implementing it on Arty A7, hmmm | 06:53 |

| Ritish | grep -r microwatt gives too many files hahah | 11:21 |
| Ritish | btw, am I supposed to build the kernel before doing anything with these files | 11:21 |

| lkcl | Ritish: if you've done anything - anything at all - with microwatt - then LITERALLY just substitute the core. | 16:03 |
| lkcl | then you repeat whatever-it-was-that-you-dif | 17:07 |
| lkcl | did | 17:07 |
| lkcl | the idea here is to demonstrate that the libresoc.v core works, but by leveraging a KNOWN GOOD position | 17:08 |
| lkcl | (to you) | 17:08 |
| lkcl | the ONLY change that you make is | 17:08 |
| lkcl | substitute the core | 17:08 |
| lkcl | nothing and i do mean NOTHING else | 17:08 |
| lkcl | that is absolutely critically important | 17:08 |
| lkcl | DO NOT attempt to change substitute the core AND {insert-anything-else, no matter what it is} | 17:09 |
| lkcl | ONLY do EXACTLY and PRECISELY what you have done before | 17:09 |
| lkcl | ok? | 17:09 |
| lkcl | this is an extremely important Engineering / Knowledge (Epistemology / Advaita Vedanta) lesson that you *cannot* get "university courses" about | 17:10 |
| lkcl | it is *applied* Advaita Vedanta. unfortunately you need to go back about 10 years of very stupid edits to the wikipedia page to find a good definition | 17:11 |
| lkcl | 1 se | 17:11 |
| lkcl | c | 17:11 |
| lkcl | Upamāṇa (उपमान) | 17:15 |
| lkcl | https://en.wikipedia.org/w/index.php?title=Advaita_Vedanta&oldid=737105595#Epistemology | 17:16 |
| lkcl | "comparison" | 17:16 |
| lkcl | if the difference is zero (in the *results*) then you KNOW that the functionality is the same | 17:16 |
| lkcl | but if you make TWO changes, and there is a difference (in the results), how do you know which change caused the difference? | 17:17 |
| lkcl | you can't tell, can you? | 17:17 |
| lkcl | it could be either OR BOTH of the changes | 17:17 |
| lkcl | the vast majority of what i do is using that comparison-inference technique, to track down any problems | 17:18 |
| lkcl | this is also not taught in schools or universities. | 17:18 |
| openpowerbot | [mattermost] <Ritish> didn't think a sanskrit word would be brought up here fr haha | 17:20 |
| openpowerbot | [mattermost] <Ritish> Okay, I think I've got the idea now, Previously I only ran microwatt, like, an led popped up(kind of) | 17:23 |
| openpowerbot | [mattermost] <Ritish> And this time, instead of the original microwatt core (of my initial experiment on microwatt) I'll just replace it with libresoc.v (which is to be renamed as microwatt.v) | 17:23 |
| openpowerbot | [mattermost] <Ritish> Very clear! | 17:23 |
| openpowerbot | [mattermost] <Ritish> Initially, I thought we were kind of interchanging the names of libresoc.v and external_top_core.v | 17:23 |
| openpowerbot | [mattermost] <Ritish> Which brought me nowhere lol | 17:24 |

| ghostmansd | Fuck. I spent literally several hours trying to understand why postinc didn't work. | 20:48 |
| ghostmansd | Long story short, the instruction name is changed dynamically. | 20:48 |
| ghostmansd | if 'u' in ins_name and self.is_svp64_mode: | 20:49 |
| ghostmansd | ldst_pi = yield self.dec2.rm_dec.ldst_postinc | 20:49 |
| ghostmansd | if ldst_pi: | 20:49 |
| ghostmansd | ins_name = ins_name.replace("u", "up") | 20:49 |
| ghostmansd | So annoying and weird. | 20:49 |
| ghostmansd | Meanwhile tests explicitly check sv.ldu/pi. | 20:49 |
| ghostmansd | Do we really need to support this instead of allowing only sv.ldup? | 20:51 |
| ghostmansd | OK, I think I understand how it works. Creep. | 21:11 |
