Matthew Croughan has a P550 and I've tried compiling things on it. We've seen a lot of things fail on it which makes me think there's something wrong. How does it perform for you? fail as in...? | 13:59:50 |
| dramforever | random userspace crash? | 13:59:55 |
 Tristan Ross | A lot of test failures like bus errors and io errors | 14:00:21 |
 Steven Keuchel | It's not as stable as I would like because the board crashes about once a week, but I am not running into the problems you describe. I have fewer tests timing out than on the sg2042, and other test failures are clearly software, not hardware related. | 14:06:57 |

| Tristan Ross | Had to look at the chat history, one of the things we saw were GCC could sometimes throw a bus error. Some git and gettext things had io errors. | 14:12:57 |
| dramforever | anything in dmesg when that happened? | 14:21:34 |
| Tristan Ross | Yeah, there were dmesg things but it'll be hard to scroll back to get that lol | 14:26:00 |
| dramforever | anyway, my point about reliable hardware just got strengthened | 14:31:12 |
| dramforever | although this could very well be a configuration issue, like clock being set slightly too high, or a one off hardware problem, or power supply issue ... | 14:31:39 |
 zimward | sounds a lot like something like that. but yeah, if we get something it should be something that has been tested to keep running for thousands of hours without crashing | 14:32:38 |
| dramforever | generally these things work is they sell them to us and get free testing and software dev work... | 14:33:32 |
| zimward | i know, very much the pine64 development strategy. | 14:33:57 |
 Alex | No amount of software dev will fix bad hardware though.
Not when the hardware flaws are unpatchably bad. | 14:55:22 |
| zimward | the difference being that the inertia of riscv is unprecedented compared to any isa ever, so that situation is quickly changing | 14:56:41 |

| dramforever | @rosscomputerguy:matrix.org: random sigbus on 7700x is a known thing, there should be a firmware update that fixes it | 00:15:31 |
| dramforever | maybe eio is the same thing | 00:15:45 |
| Tristan Ross | Oh | 00:16:57 |
| dramforever | also, ask and you shall receive, updates on the sg2044 https://www.reddit.com/r/RISCV/comments/1lvm7j7/sophgo_technology_newsletter_20250709/ | 02:15:10 |
| dramforever | PLEASE do not make this a scuffed chip again | 02:15:27 |
| dramforever | knocking on wood so much | 02:15:36 |

| no-mood | Hi all, is there any chance that the RISC-V toolchain will be packaged for Nix?

https://github.com/NixOS/nixpkgs/issues/376165 What for? | 10:58:19 |
| no-mood | In reply to @alex:tunstall.xyz
What for? I'm working on a LKM on (simulated) risc-v, and without the toolchain I'm kind of stuck.
I've tried to do it manully without success (first step of https://gem5.googlesource.com/public/gem5-resources/+/HEAD/src/riscv-fs/README.md) | 11:00:19 |
