OMAP3430 spurious interrupts

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Following patch changes interrupt processing for OMAP3 to check for spurious
bits and automatically ack if they are present. This allows the "bad irq" error
message to be generated, but prevents system getting stuck in un-acked
interrupt loop.

It would be very nice if somebody from TI could elaborate what exactly is
going on with these "spurious" interrupts, which according to TRM are
only generated when interrupt mask is modified within 10 cycles of raising
an interrupt. This seems to happen quite a bit, easily triggered by using
serial console on ES2.0 hw.
