It is key that the actual relevant code from bitbake is used in order to make sure that results are consistent with actual use in recipes. 102975 1 chris.laplante 2025-10-16 15:32:56 +0000 In my limited free time I have started playing around with an implementation of this using Pyodide and Web Workers.
