Subject: [ECOS] sa11x0 spurious interrupts
Date: Tue, 13 Feb 2001 01:19:00 -0000	[thread overview]
Message-ID: <867l2vuel3.fsf@halftrack.hq.acn-group.ch> (raw)

Hello,

While looking at the way the sa11x0 hal's routine 'hal_IRQ_handler()' decodes
interrupt sources, I noticed that when it does not find an interrupt source,
the routine returns CYGNUM_HAL_INTERRUPT_NONE, which equals to -1 for this
platform. However, the common ARM code in "vectors.S" assumes that a spurious
interrupt always have the vector #0. And worse, 'handle_IRQ_or_FIQ' will call
'hal_interrupt_handlers[-1]' which contains 0 and thus reboot!

Did I miss something?

Thanks,

Robin
