Nixpkgs takes a fair bit of memory to evaluate.
I can't recall, but it's probably on the order of a few hundred MiB minimum.
I've seen some evals go beyond 1 GiB, though I think most cases aren't that large. 4 GB if you want to nix search 🫠| 20:44:28 |

^ Requires evaluating all of Nixpkgs lol i'm still of the opinion that it doesn't need to and could do with a small fraction of that https://discourse.nixos.org/t/nix-search-a-faster-better-nix-search/48568/19 | 20:49:00 |
| Alex | It absolutely shouldn't need to (e.g. why not pre-evaluate it into a DB you can quickly search).
But it does. | 20:49:50 |
| fgaz | it does pre-eval on the first search you perform. but even that first search shouldn't require all that memory, see the post I linked above | 20:51:03 |
| fgaz | or did you mean a downloadable db? | 20:51:39 |
| Alex | It could be downloaded.
That's just an idea of one way of implementing it. There are probably others.
And yeah, I can imagine how it could be possible to trim a lot of the memory usage if you only evaluate the metadata you need and not the whole derivation graph. | 21:05:24 |
 GenericNerdyUsername | like nix-index? | 21:15:22 |

 Tristan Ross | After a month, my VisionFive2 has finished building a graphical version of my config. It has COSMIC now and ssh should work. | 15:01:19 |
| Tristan Ross | It also went from 25.05 to 25.11 | 15:05:27 |
 dramforever | MONTH | 16:53:27 |
| Tristan Ross | In reply to @dramforever:matrix.org
MONTH Yes, it really took that long. It finished some time last night since it only had 30 derivations to finish. | 17:05:48 |

| Tristan Ross | Has anyone gotten graphics to work on the VisionFive2? I'm using the nixos-hardware module. | 05:33:20 |
| dramforever | it doesn't work, the HDMI driver is not in mainline | 10:40:06 |
| dramforever | (yes, you've been using mainline linux on your vf2 this whole time) | 10:40:33 |
| Tristan Ross | In reply to @dramforever:matrix.org
it doesn't work, the HDMI driver is not in mainline What about the fork? Would that work? | 12:30:01 |
| Alex | In reply to @rosscomputerguy:matrix.org
What about the fork? Would that work? If you mean the vendor's branch, in my experience no.
(The "upstream" branch runs into a kernel panic on boot when HDMI is connected. The "dev" branch is a nightmare to compile.) | 13:23:44 |

| craigbro | greetings. I just install nix using the project installer on my orangepi rv2 running ubuntu. | 02:22:17 |

| craigbro | thanks for all the work to get it working this far | 02:22:47 |
| dramforever | just have to go full nixos now | 02:23:19 |
| dramforever | (i don't know if there's anything ready for that) | 02:23:32 |

| craigbro | so the binary caches listed on the wiki page run just fine. However, until I added them, I consistenty got a segfault patching libpcre while building bootstrap-tools (on every branch/tag/release I tried) | 02:27:44 |
| dramforever | whwat does cat /proc/cpuinfo say | 02:28:22 |
| dramforever | just, the first core | 02:28:30 |
