Hi
The patch 0e4c2eeb758a91e68b9eaf7a4bee9bd5ed97ff2b ("alpha/PCI: Replace
pci_fixup_irqs() call with host bridge IRQ mapping hooks") breaks
networking on Alpha for me. I have an Alpha Avanti server with tulip
network card.
The patch 0e4c2eeb breaks it so that I get MCE when the network card
driver is loaded. The patch 814eae59 fixes the MCE, the system boot
completes, but the network card doesn't receive any interrupts (and soon
it reports warning about timeout on tx queue). All kernels in the 4.14
branch have this bug.

Thanks for the report! Lorenzo has been on vacation and is probably
buried in email, but I'm sure he'll be on this as soon as he digs out.

Matbe the map is wrong for Avanti? Is there some way to check that?

I think the problem is in noname_init_pci(), that, AFAICS, in order to set-up
the IRQ level, it requires IRQ mapping to be carried out. Joy.
See:
sio_fixup_irq_levels()
and in particular
sio_collect_irq_levels()
Does this horrid hack help (to understand where the problem is - how to
fix it that's another story) ? Compile tested only.

Can you check if this patch fixes the issue please ?
I suspect we ought to map IRQs early in this platform so that we are
able to detect how platform code should set them up.
Thanks,
Lorenzo

This patch breaks it even more - so that the IDE controller doesn't
receive any interrupts. I can't tell if the netowrk card receives
interrupts or not, because it doesn't mount the root filesystem.

I doesn't seem to increase any other counter when I send a network packet.

SIO is used in multiple alpha platforms - should this patch work on all
of them?

Yes, I expected that after having a more thorough look, that's why
I posted another patch.

Ok, so it looks like my understanding was right. pci_assign_irq() is
not supposed to be used in arch code; I think I can rework
noname_map_irq()
to update the level_bits (ie sio_fixup_irq_levels()) just for the IRQ
that is being mapped but I need help testing it.
Thanks for the prompt testing.

This patch does nothing but assigning the IRQ earlier, as I said
in another thread I will modify it to make it simpler and avoid
relying on pci_assign_irq() - it was just to understand if my
assumption was right.

I have reworked the sio code so that now the IRQ level is set upon IRQ
mapping; patch below - it needs thorough testing since I can't test on
alpha and I do not have in-depth knowledge of alpha platform code.
Please let me know if it fixes the issues.
Thanks !

Networking doesn't work, other interrupts work.
With this patch, /proc/interrupts shows one interrupt for the network card
(it used to be zero without this patch).

It is getting harder to understand what's going on, here's an
incremental patch with some logging, it would be ideal to add
a similar logging with a working kernel so that we can actually
compare the IRQ level registers programming, please test it
when you have time.

This patch works. The patch contains some small changes in the function
noname_map_irq compared to your previous patch and these changes make it
work. If I revert these changes, networking doesn't work.
I'm attaching dmesg of working kernel (4.14.12 with this patch) and
non-working kernel (4.14.12 with your previous patch with 'pr_info("%s:
level bits' added).

Yes - I am slowly understanding how this Alpha platform deals with IRQs,
thank you for your help and apologies for the drawn-out fix, I just
can't test on this platform.
Patch below (minus pr_info that I will remove) should be the final one,
please test it and provide me with logs so that I can check.
Thank you very much.
