I can't figure out at all WHY a generic interface has anything to do with edge trigger configuration. I assume this is (Nvidia) GIC specific nonsense, so why are you inflicting this on every caller of this interface unconditionally w/o explaining what the impact of this change might be and why it does not cause havoc for any existing caller? This is function is implemented in kernel/irq/ not in foo/gic/ so you better come up with some coherent explanation. Thanks, tglx
