As I sadly found out, a s3 cycle makes the AMD's iommu stop sending interrupts
until the system is rebooted.
I only noticed it now because otherwise the IOMMU works, and these interrupts
are only used for errors and for GA log which I tend not to use by
making my VMs do mwait/pause/etc in guest (cpu-pm=on).
There are two issues here that prevent interrupts from being generated after
s3 cycle:
1. GA log base address was not restored after resume, and was all zeroed
after resume (by BIOS or such).
In theory if BIOS writes some junk to it, that can even cause a memory corruption.
Patch 2 fixes that.
2. INTX (aka x2apic mode) settings were not restored after resume.
That mode is used regardless if the host uses/supports x2apic, but rather when
the IOMMU supports it, and mine does.
Patches 3-4 fix that.
Note that there is still one slight (userspace) bug remaining:
During suspend all but the boot CPU are offlined and then after resume
are onlined again.
The offlining moves all non-affinity managed interrupts to CPU0, and
later when all other CPUs are onlined, there is nothing in the kernel
to spread back the interrupts over the cores.
The userspace 'irqbalance' daemon does fix this but it seems to ignore
the IOMMU interrupts in INTX mode since they are not attached to any
PCI device, and thus they remain on CPU0 after a s3 cycle,
which is suboptimal when the system has multiple IOMMUs
(mine has 4 of them).
Setting the IRQ affinity manually via /proc/irq/ does work.
This was tested on my 3970X with both INTX and regular MSI mode (later was enabled
by patching out INTX detection), by running a guest with AVIC enabled and with
a PCI assigned device (network card), and observing interrupts from
IOMMU while guest is mostly idle.
This was also tested on my AMD laptop with 4650U (which has the same issue)
(I tested only INTX mode)
Patch 1 is a small refactoring to remove an unused struct field.
Best regards,
Maxim Levitsky

This will give IOMMU GA log a chance to work after resume
from s3/s4.

This is more logically correct and will also allow us to
to use mask/unmask logic to restore INTX setttings after
the resume from s3/s4.

Use IRQCHIP_MASK_ON_SUSPEND to make the core irq code to
mask the iommu interrupt on suspend and unmask it on the resume.
Since now the unmask function updates the INTX settings,
that will restore them on resume from s3/s4.
Since IRQCHIP_MASK_ON_SUSPEND is only effective for interrupts
which are not wakeup sources, remove IRQCHIP_SKIP_SET_WAKE flag
and instead implement a dummy .irq_set_wake which doesn't allow
the interrupt to become a wakeup source.

Suravee, can you please have a look? These look like v5.16 material.
Thanks,

Could you just apply these patches on top of 5.15 kernel and see if you get the warning?
If something could case it is I think patch 1, it does move the GA log enabled
to be a bit later.
I also added few warnings there. I wonder why your dmesg quote doesn't contain the C line
where the warning happens.
In partucular I added:
if (WARN_ON(status & (MMIO_STATUS_GALOG_RUN_MASK)))
That will fire if GA log is already running (maybe BIOS enabled it? - it really shouldn't do that)
And that:
if (WARN_ON(i >= LOOP_TIMEOUT))
also should not happen and worth to be logged IMHO.
Best regards,
Maxim Levitsky

Which points to patch one and "if (WARN_ON(i >= LOOP_TIMEOUT))"
Hope that helps

Could you post the whole dmesg, or at least:
dmesg | grep AMD-Vi
What CPU does your system have?
I suspect that your system doesn't GA log feature enabled in the IOMMU, and the code never checks
for that, and here it fails enabling it, which before my patches was just
ignoring it silently.

Great, your system does seem to support GA log
(but a patch to check if, other that assume blindly that it is supported is
something that should be done).
So could you bump the LOOP_TIMEOUT like by 10x or so and see if the problem goes away?
(that code should be rewritten to time based wait and not just blindly loop like that,
I also can prepare a patch for that as well).
Best regards,
Maxim Levitsky

Hi
I've done quite a few restarts with the LOOP_TIMEOUT increased and
I've not seen the issue since
Cheers

Great, so the problem is solved I guess.
Thanks for the help!
I'll send a patch for this in few days to replace this and other similiar timeouts
with a proper udelay() wait.
