minus-squarecheet@infosec.publinkfedilinkarrow-up43·1 年前PS2 keyboards use interrupts rather than polling in USB, meaning every time a key is pressed the CPU stops what its doing to process it.

minus-squaredrath@lemmy.worldlinkfedilinkarrow-up5·1 年前I’m wondering, is it still the case for mobos with Super IO?
minus-squaredan@upvote.aulinkfedilinkarrow-up4·1 年前Super IO does still use interrupts as far as I know. The PS/2 protocol is interrupt-driven, so it’s not possible to use a PS/2 keyboard or mouse without interrupts.
