From 7bd328f9d24b4fb23c7d5de50bddbb60828c9ffc Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Wed, 10 Aug 2022 14:34:22 +0100 Subject: bitbake: BBHandler/cooker: Implement recipe and global classes We have some confusion for users since some classes are meant to work in the configuration space (or "globally") and some are meant to be selected by recipes individually. The cleanest way I could find to clarify this is to create "classes-global" and "classes-recipe" directories which contain the approproate classes and have bitbake switch scope between them at the appropriate point during parsing. The existing "classes" directory is always searched as a fallback. Once a class is moved to a specific directory, it will no longer be found in the incorrect context. A good example from OE is that INHERIT += "testimage" will no longer work but IMAGE_CLASSES += "testimage" will, which makes the global scope cleaner by only including it where it is useful and intended to be used (images).
