 K900 | I mean | 08:44:08 |
| K900 | Yeah | 08:44:09 |
| K900 | That's kind of the problem | 08:44:12 |
| K900 | We probably need, like, at least a full rack to get to reasonable Hydra coverage | 08:44:26 |
 amaan | it isn't terrible @ 5.2ghz but it's still 2 cores | 08:44:27 |
| amaan | yeah | 08:44:30 |
| K900 | I don't even know | 08:45:55 |
| K900 | How many cores a single rack can have these days | 08:46:08 |
| K900 | The last s390x I've had the questionable pleasure of using was a ... z10? | 08:47:10 |
| amaan | think the one i have access to is z15 | 08:49:16 |
 Artemis Tosini (NixOS) | iirc there's no support for alpha in nixpkgs. Not having hydra isn't a total dealbreaker, Audrey and I developed much of NixBSD both native and cross with just our own machines | 15:55:15 |
| Artemis Tosini (NixOS) | If someone does write alpha support please merge it, I looked at it once and dis ome work but got bored before I made a PR, so noe veryone has to do it again | 15:56:20 |
 Puna | i might do sparc64 eventually, when powerpc64 is further along and i have to worry less about other things. scored a sun ultra 2 + monitor when my uni dissolved their sun pool | 16:05:57 |
 Alyssa Ross | Are toolchains actually going to keep supporting these dead architectures? | 16:06:50 |
| Puna | ¯\_(ツ)_/¯ | 16:07:09 |
| Puna | as long as there are ppl willing to chip in with code & testing, maybe? | 16:09:43 |
| Puna | more willing than for itanium at least | 16:10:01 |
 Aelin | considering GCC only dropped Itanium like last year I wouldn't worry about sparc64 | 16:10:13 |
| Alyssa Ross | I'm fine with having Nixpkgs support them, but I'd be significatly less fine with Nixpkgs trying to support dead architectures that upstream toolchains have dropped support for. | 16:10:37 |
 7c6f434c | Well, if we have avrgcc, one might argue for some flexibility on what counts as upstream toolchain (but of course the expectations on what patches can be pushed for compatibility fixes are quite restrictive for such a platform) | 16:18:45 |
| Puna | does LLVM even support alpha? | 16:23:49 |
| Puna | doesn't look like it, so anything needing LLVM or Rust would be off the table. not seeing any mentions of it in Go either. GHC can identify it, would have to yoink & patch another prebuilt compiler from debian to test that though. | 16:32:37 |
| Artemis Tosini (NixOS) | nixpkgs can do ppc32, which go won't do | 19:00:32 |
| Puna | yeah i guess no Go isn't much of a blocker | 19:15:21 |
| Puna | (it's also a no-go on ppc64 cus they raised their baseline way too high, and refuse to undo it) | 19:17:11 |

|  @panic:sft.lol left the room. | 20:36:06 |

|  aphasic joined the room. | 06:35:06 |
| Artemis Tosini (NixOS) | the most cursed architecture one could usefully add to nixpkgs might be netbsd-vax. Relies on somewhat better netbsd support though, most of the BSD work has been focused on FreeBSD | 13:34:01 |
| Artemis Tosini (NixOS) | FreeBSD is fairly aggresive about dropping platform support, the only supported architectures for 16 are amd64, aarch64, armv7, powerprc64 (big endian), powerpc64le, and riscv64 (hard float) | 13:35:34 |
