Hi, One question about Interrupt, I read in blog http://lkdp.blogspot.com/ that " When an interrupts are being masked, they are not lost, rather PIC remembers those and do send the interrupt to CPU when CPU unmasks that interrupt line." But in book I read that "If the kernel allows itself too much time to process an ISR when interrupts are disabled, it can (and will) happen that interrupts are lost."
My question is that when we mask the interrupt, do they lost or do they get send to processor when they unmasked back?? Thanks Shyam
