It should enable the interrupt - the end of that does: if (handle != handle_bad_irq && is_chained) { irq_settings_set_noprobe(desc); irq_settings_set_norequest(desc); irq_settings_set_nothread(desc); desc->action = &chained_action; irq_startup(desc, true); } and indeed, I see that it gets enabled on Assabet. That irq_startup() should result in the irqchip's irq_startup, irq_enable, or irq_unmask method being called. So, that should result in the IRQ to which the sa1111 is connected being unmasked. Chained interrupts don't appear in /proc/interrupts. > I traced the code in the interrupt controller (pxa_cplds_irqs), the SA1111 > physical line is not set (even with an AT/2 keyboard connected, and I don't > think anybody tried this AT/2 on a lubbock for a long time). Hmm. Looking at pxa_cplds_irqs, that's trying to support the CPLD interrupts using a very very old and inefficient technique. The whole point of the chained interrupt system is to avoid several overheads in the system... I'm curious why PXA moved away from that. One of the problems is that we end up nesting irq_entry()/irq_exit() which contains a lot of code, eg trying to run softirqs. All that stuff is pure overhead because we'll never get to run anything like that in this path. I'm also very concerned that the conversion is wrong. The old code has this comment in the irq_unmask function: - /* the irq can be acknowledged only if deasserted, so it's done here */ - LUB_IRQ_SET_CLR &= ~(1 << lubbock_irq); In other words, we "acknowledge" (really clear the latched status) of the interrupt _after_ we've serviced the peripheral, not before. The new code tries to clear down the interrupt when masking it - in other words, before the peripheral handler has had a chance to clear down its interrupt. I suspect you're seeing about twice as many interrupt counts on your ethernet interface because of this - you'll be entering the handler once for the real interrupt, but because the clear-down was ineffective, you end up re-entering it a second time when hopefully the peripheral is no longer asserting the interrupt. > The interrupt is for sure masked, and therefore the SA1111 interrupts are not > fired.
