That's a bogus argument because:
- MMIO isn't much used by the IDE drivers much (normally the inline
ins*()/outs*() accessors are used;
- that's used only by generic IDE code, not by the drivers about which
I'veargued;
I've already agreed that the generic code would probably win from using
ioread*()/iowrite*().
It's already making function calls, without the benefit of inlining and
I'm afraid you're wrong here.
I'm afraid you are the one who is wrong. The IDE layer is duplicating a
generic level of indirection with its own code - purely because IDE
pre-dates that core functionality. The whole IDE layer indirection can go
away because Linux has caught up with the needs of the IDE layer.
What IDE indirection you're talking about anyway?
