Hi hackers,
I have to hijack lpt_intr() from lpt device driver
(/sys/dev/ppbus/lpt.c) to measure latency.
Is this right =
BUS_TEARDOWN_INTR(old interrupt handler);
BUS_SETUP_INTR(new interrupt handler);
?
In fact I could not get resource structure and the cookie from lpt
driver, so before doing bad things I would want to know if this is the
right way to hijack a hardware interrupt handler.
Thanks in advance,
