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 | 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 | there are a million (hyperbole) Indian startups doing exactly that! | 14:34:52 |
| Pratham Patel | 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 |

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 | 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 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 |
