Can you try to do that for the mmconf xbar in memory space too > while being at it? If I manage to convince mst in using macro approach. PS: Although his build_append_foo() functions have tremendously improved dynamic AML generation (made it much less error-prone), the current acpi-build.c becomes harder to read (just look at new pcihp parts). So I'm arguing in favor of more simple/intuitive API approach even if it uses macros (I'm really not fun of it, but result is much clear/maintainable code). > > cheers, > Gerd > >
