Why does the keyboard have to interrupt the CPU that's mean 
@stellarskylark@solarpunk.moe @astrid@fedi.astrid.tech USB is so much more polite 
@stellarskylark @natty I don't even think it's that polite to the USB controller, it probably has an interrupt handler in there too
@astrid @natty @stellarskylark My memory is a bit fuzzy but doesn't the controller have to poll the keyboard for new events instead of the keyboard signaling that it has an event ready?

@astrid @natty @crumbcake @stellarskylark Yup, it has to poll (at least unless the device is suspended, as then it can trigger a remote wakeup - the only opportunity for a device to initiate communication).
