 Kamilla 'ova | combine emulation/small physical hardware like the VisionFive2
what? canadian cross? | 13:06:19 |
 Jake Hillion | Haha, worded that poorly. I mean I have a big x86_64 machine that can do emulation, and a small RISC-V machine that can do native builds. Hoping that between the two I can bootstrap properly. | 13:08:12 |
 Steven Keuchel | you can cross-compile an sdcard first, and then do a native recompilation. I think it takes ~1w to natively compile a basic system on the VF2 only, 3-4days on the Premier / Megrez boards, and 1-2 days on the Pioneer. | 13:12:37 |
| Steven Keuchel | qemu user mode emulation works for many packages and is ok performance wise. system emulation is comparable to the JH7110, so keep your expectations in check. | 13:14:51 |
| Steven Keuchel | I had 8 VMs with 8 cores each running on a 64core threadripper at some point and it was a miserable experience :P | 13:15:37 |
| Jake Hillion | Awesome, thank you! And hopefully last question for now, cross compiling the SD image comes from the instructions on https://wiki.nixos.org/wiki/NixOS_on_RISCV/VisionFive_2? I'm currently trying to bootstrap from their Debian but would be easier in NixOS. | 13:24:48 |
| Steven Keuchel | did not know that wiki page existed. I started from https://github.com/NixOS/nixos-hardware/tree/master/starfive/visionfive/v2 but that seems to be the same thing | 13:26:44 |
 Nick Cao | Shameless plug: I have vf2 sd image cached at https://hydra.nichi.co/job/nixos/riscv/visionfive2 | 13:27:11 |

 implr | Anyone tried to build something without crosscompiling (so system=riscv64-linux; no crossSystem), via qemu-user or natively recently? | 20:40:33 |
| implr | On current unstable, bison is failing doCheck for me, but it's in one of the bootstrap stages, so it's a huge pain in the ass to override | 20:40:58 |

 Alex | NixOS compiled fine for commit 3a228057.
(See https://github.com/AlexandreTunstall/nixos-riscv/blob/6fc5181216631eaeec703fb09028b127c01d27a1/flake.lock#L9) | 20:42:47 |
| Alex | So the regression has happened in the past month or so. | 20:43:11 |
| implr | Let me double check if that commit works for me, maybe I did something dumb | 20:43:37 |
| implr | hm, it does not, fails the same way | 23:13:52 |
| implr | I'll try your flake as-is | 23:13:57 |
| Alex | In reply to @implr:hackerspace.pl
I'll try your flake as-is See the instructions in README. As-is, it requires some x86 cross-compilation for GHC (or you can edit out the Haskell dependencies). | 23:14:55 |
| implr | I just want to see if the bootstrap builds, so I'm doing .#nixosConfigurations.nixos.pkgs.bash | 23:15:37 |
| implr | if that passes it's already further than I got | 23:15:45 |
| Alex | Well, if that evaluates and doesn't complain about needing an x86_64 machine, it should be OK (it could still require GHC because of ShellCheck being used in writeShellScript). | 23:16:59 |
| implr | Oh, I am on a amd64 machine with extra-platforms = riscv64-linux right now, so that should just work, but that might be the difference which makes bison work for you and not me | 23:20:01 |
