Restructure extension to cache extra ROCm and XPU dependencies#257
Merged
Conversation
Before this change the `torch-extension` directory was just a derivation that built an extension for a given configuration + build set. The downside of this approach was that we could not easily get things like - The standard environment to be used by dev shells. - Overrides for caching. For instance, we override ROCm's `clr` and XPU's `oneapi-torch-dev` and `onednn-xpu` to use stdenv with an old glibc. This change modifies `torch-extension` so that we can instantiate it given a build set. A set is returned that can give access to the things mentioned above, as well as mkExtension and mkNoArchExtension functions. We assign this set to the corresponding build set, so that it is directly accessible from the build set.

is this a minimal requirement or a strict requirement ?

We target this version because it was what Torch itself is compiled against (or at least Torch 2.5 or 2.6), it results on working on any glibc version >= 2.27.
