@doge.2:matrix.orgdoge.2Redacted or Malformed Event01:09:58
@doge.2:matrix.orgdoge.2Download flake.nix01:10:17
@doge.2:matrix.orgdoge.2i uploaded my configuration and flake if it helps01:10:28
@thefossguy:matrix.orgPratham Patel (you can mention me)There is no first party binary cache at the moment01:12:03
@doge.2:matrix.orgdoge.2is everything in my configuration and flake correct however?01:44:12
@thefossguy:matrix.orgPratham Patel (you can mention me)Can you share a GitHub/GitLab link? My phone says .nix files are binary lol03:49:51
@thefossguy:matrix.orgPratham Patel (you can mention me) You might want to replace the lib.mkForce with a lib.mkBefore under nix.settings in your configuration.nix. 06:12:54
@thefossguy:matrix.orgPratham Patel (you can mention me)Also, you're using the wrong nixpkgs url06:13:47
@thefossguy:matrix.orgPratham Patel (you can mention me)the cache can only be used if you point your nixpkgs to either misuzu's nixpkgs fork for riscv or Nick Cao's fork of nixkpgs for riscv06:14:18
@thefossguy:matrix.orgPratham Patel (you can mention me)otherwise, you're trying to find the output of nixos/nixpkgs in misuzu's and Nick Cao's binary cache, which won't be there06:15:02
@thefossguy:matrix.orgPratham Patel (you can mention me)On the topic of a binary cache for riscv, other than "we don't have [funding for] powerful enough hardware available," is there anything else that needs to be ironed out before we start searching for powerful riscv hardware to put in hydra06:16:26

@alex:tunstall.xyzAlexImportantly, doesn't the hardware also need to be reliable?06:17:21
@thefossguy:matrix.orgPratham Patel (you can mention me)I have like 5 coupons for Oasis (when it gets out) which gives a 50% discount. I can give 4 or all of them to the nixos foundation.06:17:46
@thefossguy:matrix.orgPratham Patel (you can mention me) Yes. But what I actually meant to ask is, "Are we at a stage where the only obstacle for building riscv binaries in hydra is the unavailability of powerful+reliable hardware?" 06:19:05
@alex:tunstall.xyzAlex

Right. We already know from experimenting that most of the important packages build.

Is there precedent of running Hydra against a platform with no official support? (maybe aarch64 did this at some point?)

06:21:05
@thefossguy:matrix.orgPratham Patel (you can mention me) One thing that I know of the top of my head is that the entirety of stdenv doesn't feel ready. Like stdenv.isRiscV64 is missing but stdenv.targetPlatform.isRiscv64 and stdenv.hostPlatform.isRiscv64 exist. 06:23:24
