Indeed it does :-)
We could potentially use the reset_irq_delivered/get_irq_delivered APIC functions to implement interrupt catch-up but I think it would be better to try to merge Jan's generic IRQ delivered API first.Which one? I'm a bit tired of rebasing versions that will only be rejected again. :)
Yeah, I appreciate your frustration here. Regards, Anthony Liguori
