did you try to enable certain RV optimizations? Which ones? | 15:45:15 |
 raitobezarius | Whatever the VF2 has in terms of extra extensions I imagine? | 15:45:36 |
| raitobezarius | or does the gcc uses all the extensions it can find when compiling? | 15:45:47 |
| misuzu | vf2 has rv64imafdc_zbb isa
https://rv.drom.io/ | 15:48:04 |
| misuzu | rv64imafd==rv64gc | 15:49:44 |
| raitobezarius | Oh I thought it had some experimental vector extensions | 16:23:45 |
 GenericNerdyUsername | are they any complications with the zbb bit? | 20:54:07 |
| GenericNerdyUsername | things might only support all (b) or nothing, not subcomponents of the bitmanip extension | 20:54:31 |

are they any complications with the zbb bit? not ones I am aware of | 13:52:33 |
| raitobezarius | I mean | 13:52:37 |
| raitobezarius | If you support too small subsets, you just don't get the feature | 13:52:46 |

 Snektron | misuzu: when you enter nvme scan in the u-boot console does it come up with anything? | 00:10:10 |
| Snektron | Also, that version of u-boot wont have internet because the ethernet nodes are missing from the device tree, I think. Also also, its missing the code that is required to fix up the memory node on models that have 8 GB memory | 00:11:53 |
 @withoutwithin:matrix.org | starting to think that my bell router DHCP server is cursed somehwo | 02:07:49 |
| @withoutwithin:matrix.org | oh wait what | 02:08:12 |
| @withoutwithin:matrix.org | the other network port works | 02:08:16 |

 colemickens | Hi, I have something I don't understand -- I can cross-compile [a derivation] from a (x86_64 builder) for aarch64, but when I try to build for riscv64-linux, I get a dependency chain that includes bootstrap-tools. Which I don't have available for riscv64-linux... Question - is our riscv64 support "behind"? Can I not cross-compile the bootstrap tools and use those somehow? | 05:23:08 |
| colemickens | I've looked for docs several times but haven't really made any head way. Between ghc being not natively supported, and this 'bootstrap-tools' issue, I'm having a hard time getting from a pretty minimal build to my more full nixos profile on the VF2. | 05:23:52 |
| colemickens | (aside: it strikes me as funny that I can cross-compile sway and mpv, but not bash or zellij :P) | 05:24:20 |
| colemickens | also unrelated: I have a nixos module that boots a qemu vm that can then act as a "native" riscv64 builder. A hack of a hack of floweringash's original work, but I think it might build as fast or faster than my VF2, on a huge Packet VM... | 05:26:17 |
| colemickens | also also unrelated, I have a module (again, hacked on from someone's else initial effort) that builds a very small netboot-able initrd that then 'curl's a big squashfs with stage-2. I used this to "fix" my VF2 remotely via u-boot serial access. :D It's likely to come in handy in the future. | 05:27:50 |
 trofi | Locally you should be able to build bootstrapTools with pkgs/stdenv/linux/make-bootstrap-tools-cross.nix. | 07:31:45 |
| trofi | Adding riscv64-linux to bingmt on x86_64-linux seems to work as well if I try to build bash "natively": $ nix build -f '<nixpkgs>' bash --argstr system riscv64-linux (built a few packages so far, did not get to final bash yet). | 07:38:24 |
 Alyssa Ross | colemickens: you shouldn't need the bootstrap tools to cross compile | 08:21:40 |
