t-head has a userspace erratum where the FP underflow flag is incorrectly not set if a multiply rounds away from zero to produce the smallest normal number, AFAIK the only thing this affects is the glibc regression test suite thanks for that! I am going to read up on it. | 13:44:25 |

So far, the only machines I trust for building nixpkgs are the HiFive Unmatched and the VisionFive 2. You should also count the Star64, because it uses the same SoC as the VF2 (unless you have a reason for excluding it too?) | 14:33:01 |
| Pratham Patel (you can mention me) | Ah no reason to exclude it, just forgot about it! :D | 14:33:26 |
| Alex | On the topic of implementation errata, I wonder if anyone's doing any exhaustive testing on the various RISC-V processor designs... | 14:34:10 |
| Pratham Patel (you can mention me) | there are a million (hyperbole) Indian startups doing exactly that! | 14:34:52 |
| Pratham Patel (you can mention me) | the last tenstorrent event almost a year ago in BLR was exactly that :) | 14:35:15 |
| sorear | it's hard to exhaustively test anything of that size, especially when the specs themselves are nondeterministic (memory ordering, counters) or just plain ambiguous | 14:37:22 |

it's hard to exhaustively test anything of that size, especially when the specs themselves are nondeterministic (memory ordering, counters) or just plain ambiguous Yes, that's very fair. I'd expect some amount of testing to be possible by exploiting a deep understanding of the processor design, but that's by no means simple. | 14:39:43 |
| sorear | the interesting bugs all happen because somebody miscommunicated or misunderstood the requirements | 14:40:34 |
| Pratham Patel (you can mention me) | one thing I--as a software guy and a negative XP in hardware--understand is, at that point, you're not just verifying the RISC-V ISA but also the microarchitecture :) | 14:40:47 |
| * Pratham Patel (you can mention me) is afk for dinner | 14:40:54 |
| sorear | the ISA is what it is. it can be stupid or contradictory but not wrong, because there's nothing for it to be wrong against | 14:41:37 |

If you really want some decent remote desktop experience, I would recommend wayvnc (or others), rather than this poorly packaged xrdp. I tried to install wayvnc, it fails with modemmanager build failing to find python. For now I’ve built image w/o VNC, I’ll try to build VNC on board. | 19:06:12 |

 fgaz | Scaleway now hosts RV servers based on the TH1520 https://labs.scaleway.com/en/em-rv1/ | 13:16:48 |
| fgaz | Maybe this is enough for some temporary nix-community builders? | 13:17:17 |

| Pratham Patel (you can mention me) | One more thing, as per Sipeed, it is likely that the SG2380 (the 16 core chip) might be ready in this year.
https://x.com/sipeedio/status/1763391901049463103 | 13:59:47 |
| Pratham Patel (you can mention me) | Not sure how much I believe it, considering that the initial spec has been modified (in a good way) which is likely to cause delays in things like verification and manufacturing. | 14:00:30 |
| Pratham Patel (you can mention me) | Could be a marketing "stunt" (I don't think so and i hope not) but Milk-V Oasis (the first product announced to have been using the SG2380) was planned to launch in Q4 of 2024. | 14:01:59 |
| Pratham Patel (you can mention me) | But that announcement about Oasis was before the silicon was modified for improvements | 14:02:16 |
| Pratham Patel (you can mention me) | So I'm not really sure | 14:02:20 |
| Pratham Patel (you can mention me) | Hoping it happens sooner, but I'd be happy with a few months of delay for an errata free product, hell even pay a few hundred USD more for not wasting hundreds of USDs for a buggy product | 14:03:14 |
