| Thanks a lot for this - running an NVIDIA card and an AMD GPU together in one PC is something we really want, and the split into a separately built HIP library with a small versioned interface is a clean way to do it. We read it through: it stays off unless the plugin path is set, and the normal build and output don't change. We'd like to run it on our own NVIDIA + AMD Linux setup before we bring it in, so it may take a few days. On our side we'll list the settings under their MAYA_ names in the docs, keep the test folder to the parts CI runs, and fit it on top of the GLM helper changes from [#849](https://github.com/mw00/project-maya/pull/849) -[#851](https://github.com/mw00/project-maya/pull/851) - we'll handle that ourselves. |
