How will this be selected ? Passing ->irq = 0 ?
It is selected at runtime by passing a polling flag to ata_taskfile.
That flag, in turn can be set by anything -- driver flags (for
controllers that always require polling), user variable requested at
runtime, whatever.
For ata_piix given you've destabilized it a bit would now be a good time
to submit the patches to fix the timing, register scribble and incorrect
ATAPI caching ?
Sure.
