once and for all. The i8259 does not like to be read in a loop, when an
interrupt comes in, it will return a valid value, however, if you keep
reading it until there are no outstanding interrupts, it will return 7
(which is the lpt interrupt). Change the pic handler to give an argument
to the get_irq functions of mode, which indicates if this is the first
time we are asking, or if we are just rechecking in a loop. Non-i8259
handlers can safely ignore this argument.
Tested to fix the stream of 7's problem on prep and ofppc. Got rid of
the nasty hack in ofppc with this too, and the prep machine seems to take
less interrupts now, which is a good thing.
can find.
If the initiator discovers too many targets for it to handle
(currently more than 16), then truncate to the maximum with a loud
warning message, rather than aborting.
In practice, this means that multiple targets can now be used with the
NetBSD iSCSI initiator.
