It's very late in the cycle, but I'm considering trying to squeeze this into v4.9 on the grounds that: - It's only a documentation change and can't break anything, and - Distributing it more widely may help the arm64 firmware ecosystem But I don't want to disseminate misleading or incorrect information, so if it needs clarification or wordsmithing, or even just maturation, I'll wait until v4.10. The Consumer/Producer stuff, in particular, doesn't seem 100% settled yet. Your thoughts, and especially your improvements, are welcome! Bjorn
