Where can I find the > IRQ-handler table in kernel codes? FreeBSD generates the interrupt handler table dynamically at runtime, as interrupts can be moved from one handler to another, or chained between multiple handlers. You can read the low-level interrupt handler code for the i386 in /usr/src/sys/i386/isa/icu_* (for uniprocessor kernels) and /usr/src/sys/i386/isa/apic_* (for SMP kernels). -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
