ours is an embedded
system; except for test systems, there aren't any other slots. We may be able to
force IRQs to be unshared through BIOS settings.
Either way, that
still leaves the basic questions:
must RTLinux
interrupt handlers have IRQs that are not shared with standard Linux interrupt
handlers (like USB)?
should the RT Linux
interrupt handler call rtl_hard_enable_irq before the return
statement?
