Unfortunately it can not be reverted because handle_percpu_devid_fasteoi_ipi no longer exists in next-20201214, so I don't know if it is the only problem.

This works just fine for me on both the RPi2 and 3 emulation, running a full Debian userspace. Could this be caused by the version of QEMU you are using? Here's what I have: $ qemu-system-arm --version QEMU emulator version 5.1.0 (Debian 1:5.1+dfsg-4+b1) Could you try the following hack and let me know if that helps?

It does look like I inverted the ordering of that mailbox write vs the handling of the IPI. I don't see how the IPI could mess with the mailbox (unless some creative use of irq_work / smp_call), but in any case having the write in irq_ack() as you've done below should restore said ordering. > Thanks, > > M. > > diff --git a/drivers/irqchip/irq-bcm2836.c > b/drivers/irqchip/irq-bcm2836.c > index 5f5eb8877c41..25c9a9c06e41 100644 > --- a/drivers/irqchip/irq-bcm2836.c > +++ b/drivers/irqchip/irq-bcm2836.c > @@ -167,7 +167,7 @@ static void bcm2836_arm_irqchip_handle_ipi(struct > irq_desc *desc) > chained_irq_exit(chip, desc); > } > > -static void bcm2836_arm_irqchip_ipi_eoi(struct irq_data *d) > +static void bcm2836_arm_irqchip_ipi_ack(struct irq_data *d) > { > int cpu = smp_processor_id(); > > @@ -195,7 +195,7 @@ static struct irq_chip bcm2836_arm_irqchip_ipi = { > .name = "IPI", > .irq_mask = bcm2836_arm_irqchip_dummy_op, > .irq_unmask = bcm2836_arm_irqchip_dummy_op, > - .irq_eoi = bcm2836_arm_irqchip_ipi_eoi, > + .irq_ack = bcm2836_arm_irqchip_ipi_ack, > .ipi_send_mask = bcm2836_arm_irqchip_ipi_send_mask, > };

This hack indeed brings us back to the previous situation, where we allowed the interrupt to be re-generated while handling the IPI. Still, that doesn't explain why I'm not experiencing any issue here. I hope that the various CI bots will let us know if anything is broken on real HW. M.

Sorry, I should have tried first before bothering you. No bother at all. If this works for you on more recent versions of QEMU, that'd be an interesting data point. I'm also interested in the result of the patch either way. Thanks, M.
