I'm not really sure what you mean by "runtime loading". Do you mean the kernel's implementation of loading dtbo overlays? While that is a different implementation from the one in fdtoverlay (AIUI), they're both working from the same dtb format. As we discovered attempting Ayush's proposal, it turns out that the dtbo simply doesn't have the information we need to correctly path substitutions; and it's not at all easy to add it. So, the problem of the encoding format needs to be solved regardless of which implementation is actually processing the overlays. -- David Gibson (he or they) | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you, not the other way | around. http://www.ozlabs.org/~dgibson
