Struct pic8259_simple::ChainedPics [] [src]

pub struct ChainedPics { /* fields omitted */ }

A pair of chained PIC controllers. This is the standard setup on x86.


impl ChainedPics

Create a new interface for the standard PIC1 and PIC2 controllers, specifying the desired interrupt offsets.

Initialize both our PICs. We initialize them together, at the same time, because it's traditional to do so, and because I/O operations might not be instantaneous on older processors.

Do we handle this interrupt?

Figure out which (if any) PICs in our chain need to know about this interrupt. This is tricky, because all interrupts from pics[1] get chained through pics[0].
