It's an interface that memory.c exports. If you want to mark it as internal, make this clear in the name but IMO it's a bad idea to force everyone to use grep to find where the implementation of each function is. > > Signed-off-by: Michael S.

Yes, I agree. To add to the mess, io_mem_{read,write} are just old-fashioned names for (static) memory_region_dispatch_{read,write}. I need to understand whether/how the per-arch calls to softmmu_template.h could be moved to exec.c. Then io_mem_{read,write} can just disappear, and memory_region_dispatch_{read,write} can move to memory-internal.h. Paolo >>> Signed-off-by: Michael S.
