I have a driver for a device that exists onthe PCI bus.. unfortunatly (don't ask) it has a separate interrupt as well that runs directly to int6 of the 8259. (not via the PCI bus and not configured in by the bios etc.) I've tried the following terrible hack in the driver, but it didn't seem to work. any thoughts? static void pwrfailPCIattach( pcici_t config_id, int unit) { sc_p scp; scp = sca[unit]; config_id->intline = 6; /* pretend the chip said irq 6 */ config_id->intpin = 4; /* pretend it's pin D */ /* * Allocate our (hardwired) interrupt. */ if (!pci_map_int(config_id, pwrfailintr, scp, &bio_imask)) { printf("pwrfail%d: couldn't map interrupt\n", unit); } else { printf("pwrfail%d: interrupt %d mapped\n", unit, config_id->intline); } } It get's the success message, but the interrupt is never delivered to the routine pwrfailintr(). julian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
