Hello! > So can you model the register size according to the spec and allow > 32-bit accesses from userland? I can. But i'll have to invent my own macro for encoding register IDs into the attribute, as well as drop reusing index_to_params(). Will it be OK? Upside: i can further extend "cpu id" (actually CPU index) field to 31 bit. :) It's friday evening here, work week is almost over, i'll read your replies 2 days later on monday.
