 connor (he/him) | If you all wanted to run a NixOS VM test in which a VM actually ran nix build, how would you prepopulate the VM store so it has all the necessary build dependencies (sources, etc.).
Alternatively, if you wanted to run NixOS VM tests without the sandbox (so the test itself wouldn’t produce a store path on successful run) how would you do that? | 22:08:40 |

Alternatively, if you wanted to run NixOS VM tests without the sandbox (so the test itself wouldn’t produce a store path on successful run) how would you do that? 1. You can add the inputDerivation of whatever you want to build to the VM, IIRC there's an option to add paths to copy into the VM's Nix database
2. You can use the driverInteractive version and run run_tests() (or maybe there's even just driver?) | 22:11:49 |

| connor (he/him) | Anyone have any suggestions for benchmarking https://github.com/NixOS/nix/pull/12097? I mean, I expect it to be no slower than it is currently, but how do I show that…
Would running a nix eval in QEMU with -icount and reporting the wall time from within the VM be a good way to do that? | 06:52:04 |

| matthewcroughan | trying to use rocm | 18:54:55 |
| matthewcroughan | rocmlir-rock-5.7.1 | 18:55:09 |
| matthewcroughan | https://github.com/NixOS/nixpkgs/issues/197885#issuecomment-2416994704 | 19:00:58 |
| matthewcroughan | ah does torch-bin only work for cuda? | 19:17:31 |
| matthewcroughan | https://github.com/ROCm/rocMLIR/releases/tag/rocm-6.3.1 | 19:40:29 |
| matthewcroughan | looks like it got an update to 6.3.1 yesterday | 19:40:43 |
| matthewcroughan | 6.3.1 compiles fine just by overriding to use this new source | 20:42:05 |
| matthewcroughan | but then I need magma in rocmPackages 6, which doesn't seem to build either | 20:42:28 |
| matthewcroughan | rocm in nixpkgs is close to working, but not quite there | 20:42:37 |
| 22 Dec 2024 |
| SomeoneSerge (back on matrix) | 👍️ cuda and rocm in pytorch are mutually exclusive, so I guess there must be a separate wheel | 00:19:20 |
| matthewcroughan | https://hydra.nixos.org/job/nixpkgs/trunk/zluda.x86_64-linux | 10:51:11 |
| matthewcroughan | when is the last time this even built | 10:51:18 |
| matthewcroughan | it seems like literally never? | 10:51:30 |
| matthewcroughan | how was this merged if it never built? | 10:51:34 |
| SomeoneSerge (back on matrix) | Back when rocmPackages weren't broken | 11:28:26 |
| SomeoneSerge (back on matrix) | * Back when rocmPackages weren't broken exceeding the hydra quotas | 11:28:39 |
| matthewcroughan | SomeoneSerge (utc+3): I would love to try out zluda, but do not want to wait over 7 hours for the build, or whatever it takes | 12:21:49 |
| matthewcroughan | got a cache? | 12:21:52 |
| SomeoneSerge (back on matrix) | No, sorry. I haven't got any amd hardware at home unfortunately | 12:37:10 |
| matthewcroughan | Yeah I think there's a lack of investment in the AMD community. | 12:37:30 |
