@frederiksemmel:matrix.orgFrederik Semmel Its the Orin NX luckily :) I am free to choose a different platform, I am still evaluating what is best for our AI on the edge usecase. From what you say it seems like its not going to be impossible, so I will work my way through it. I hope I can find a a good solution, if I do I will try to contribute it to nixpkgs or jetpack-nixos 16:31:01

Yeah didn't keep track of it, must've broke with a nixpkgs bump

Hey wanna publish a review on exposing extendMkDerivationArgs?
Was this in reference to an existing PR or something new?
I apologize, I've been really scattered the last two weeks :l

@glepage:matrix.orgGaétan Lepage If you happen to just wake of from 6 months spent in coma, don't worry, the triton repo still hasn't got any more tags. 22:44:38

@ss:someonex.netSomeoneSerge (back on matrix)I don't think anything short of a github action publishing automatic tags in release branches is going to work with this organization:)07:40:32
@ss:someonex.netSomeoneSerge (back on matrix)That might not either but stands a chance (they merged stuff before)07:40:56

@sielicki:matrix.orgsielickiI do not really follow the conversation on https://github.com/NixOS/nixpkgs/pull/34370623:22:57
@sielicki:matrix.orgsielicki I don't think it actually matters in this case but just want to call it out if it ever comes up again in the context of nixpkgs: to support the cuda stubs (where you can successfully link a binary against the cuda driver api with the cuda toolkit alone, despite that it doesn't include the full UMD blob), on normal distributions nvidia creates an /usr/local/cuda/lib64/stubs/libcuda.so files, which claim a SONAME with .1, but where the file on disk doesn't actually have that. That means the dynamic loader will never accidentally confuse the stub with the real library. 23:23:59
@ss:someonex.netSomeoneSerge (back on matrix)Huh23:25:10
@sielicki:matrix.orgsielickibut now, for some of the libraries that got relinked here, I think now there's two files that have the same name, and im not sure what the dynamic loader does23:25:29
@sielicki:matrix.orgsielicki * but now, for some of the libraries that got relinked here, I think now there's two files that have the same name, and im not sure what the dynamic loader does edit: maybe not under nixos but potentially for people doing nix on ubuntu or whatever23:25:52

@sielicki:matrix.orgsielickithis is his first and only post on the cmake forums and it's <3'd by rob maynard who works at nvidia23:27:24
@sielicki:matrix.orgsielickii just kinda don't get the motivation, not really clear why the FHS steam shrinking needed this23:33:25
@sielicki:matrix.orgsielickibut who knows23:33:40
@sielicki:matrix.orgsielickias long as i'm stuck on my computer on a saturday, qq: is there a strong reason to hold cudart at 12.4 in master, or just nobody raised a PR for it? 23:39:13
@sielicki:matrix.orgsielicki https://github.com/NixOS/nixpkgs/pull/322075 looks like he just never got back to handling review comments :\ 23:40:51
