Hello everybody,
I have some questions that I'd be grateful for any answers to-
Why does RTLinux provide the rtl_hard_disable_irq call? Does this perform
an analogous function to masking the interrupts by directly outb'ing to the
PICs? I am trying to simply disable the serial port interrupts for the
duration of a real time task (not just one period) so as to prevent mouse
movement introducing greater jitter into my parallel port output. Currently
I've tried calling rtl_hard_disable_irq as well as directly outbing the PICs
in both my init_module and in my fifo handler. This seems to be utterly
ineffectual - my serial mouse remains obstinately alive. Please, even if
there is a trivial solution to this, could someone please enlighten me.
Also, throughout the mailing list and documentation there are dark hints to
'ensure interrupts are disabled for only a short time'. What will happen
otherwise?
thanks in advance,
Craig Ireland
