166 BAD interrupts? that's a lot... > Now of course, iBooks being the freaky brainchild of Apple, Watch your tongue :) > they don't > do anything quite so mundane as use, you know, interrupts for the > keyboard. Oh, they do, just not in the way that a freaky i386 developer expects. When you only have 15 IRQs, reserving one for only the keyboard may not be the most efficient use of system resources... > Everything gets delivered through ADB, which appears to be > delivering heartbeat interrtupts, since it goes up by about 10 every > second. ADB, or rather the PMU, is delivering lots of things. Among others the power management events. > I wonder if anyone knew of a better way to watch for system activity in > any meaningful way? Maybe try and watch /dev/input/* ? That's where keyboard and mouse events get delivered. Then again, it all depends on your definition of a 'meaningful way'...
