Hello,

since applying the patches related to XSA-36 Xen recognizes a broken IVRS ACPI 
table and disables I/O virtualisation.

I contacted the manufacturer of the mainboard/BIOS and they want to help me by 
providing a patched BIOS - so far so good.

However, they need details about what to fix, which I don't know either.

Could you pls. give me some hints which I can forward to the manufacturer 
support?

Thanks a lot & best regards
Hans



PS: Hardware is a Gigabyte GA-970A-UD3(rev. 1.0), BIOS F7 (tested F8a, too).

PPS: I know about 'no-amd-iommu-perdev-intremap' - this does not really help 
as e.g. heavy i/o on a usb device in one domain causes other domains to 
disable the related irq etc. ...



>From the support mail:
"Our hardware team replied:

Please inform us what settings or specific detail he needs to modify on IVRS 
ACPI Table.
They will try to patch it in a special BIOS and ask customer to check. 
Or maybe you can ask Xen for a proper IVRS ACPI Table form/example and send to 
us.
We can study on this and provide a special BIOS."

I have the same motherboard.  The chipset has 2 IOAPICs: one in the NB
(00:00.1), and another in the SB (00:14.0).

As currently configured by the BIOS, the NB IOAPIC is _entirely_
disabled, with only the SB IOAPIC enabled and configured.  From
48693.pdf, it would seem that the NB is improperly configured, as
6.4.1 recommends that

"The IOAPIC should be enabled by the system BIOS and the southbridge
routing feature should be switched on. This will allow the interrupts
to be forwarded to the PIC in the southbridge. This way, if the system
boots in DOS, interrupts will still work. Once the system boots an
ACPI OS (where IOAPIC is assumed to be supported), the system BIOS
will disable the southbridge routing feature so that the masked
interrupts are masked out."

It would seem that no NB-side interrupts are going through an IOAPIC.
If so, I do not know what the impact is - somehow NB-side interrupts
are getting to the CPUs.  However, given that very few devices have
MSI interrupts enabled by the BIOS, it may be a little more of an
issue.

It seems there are two fixes available, which would be nice to see
from the BIOS vendor:

1) "the bandaid" - just remove the second IVHD IOAPIC entry.  Then,
Xen will do interrupt remapping at least for the SB IOAPIC.  I
modified the Xen source to ignore this second entry, and get the dmesg
shown below.  My system seems to run fine after the change.

2) Properly configure the NB IOMMU, even if just as set out in 6.4.1.
http://review.coreboot.org/gitweb?p=coreboot.git;a=blob;f=src/vendorcode/amd/cimx/rd890/nbIoApic.c
which I understand to be from CIMX, has the necessary code.

I suppose if it came down to it, you could add code to Xen to bang in
the necessary configuration via the 10 indirect registers for the NB
IOMMU to match up with Table 6-6, which is what the above source file
seems to be doing (although in a more generalized and therefore
complex way).  However, I do not know what, if any, possible
consequences there would be if this does not match what is being
done/reported by ACPI.

I have looked into it.  Your best references are the 970 BIOS and
Register Programming guides, to see how it _should_ be configured.
The SB8xx guides are useful if you want to see what is going on in the
SB (SB950 has some minor differences (x4 vs x2 slot), but no formal
documentation is released).  If you _really_ want to dig into it, AMD
released BIOS code via the coreboot project which implements the
configuration shown in the guides.

The problem: Because the NB IOAPIC is not configured, any interrupts
from the x16 and x1 PCIE slots are on 1 of only 4 signal lines sent to
the SB IOAPIC: INTA, INTB, INTC, and INTD (it appears a swizzle is
applied to the slots, which may tend to spread the interrupts among
the 4 pins - although slot choice will affect that).

INTA (SB pin 16) is shared with the built-in HD audio and the rear USB
3 controller.
INTB (SB pin 17) is shared with the any interrupts generated on the x4
slot, the built-in RTL ethernet, EHCI on 3 USB 2 controllers, and the
IDE device (if ports 4+5 are so configured).
INTC (SB pin 18) is shared with OHCI on the same 3 USB 2 controllers,
a 4th USB 2 controller, and the front USB 3 controller (also, if your
x16 video card interrupts via PINA, it will go here).
INTD (SB pin 19) is shared with SATA.
I think pins 21-23 are for bridge interrupts.

>From your dmesg, it looks like your Intel ethernet is on pin 19.

Thus, most of the devices are sharing interrupt vectors, with INTC
being particularly crowded (I recall you mentioning USB previously).
With a combined total of 56 available GSIs (32 NB, 24 SB), almost
_none_ of these need to be shared (SB may be a little tight).  On top
of that, although I'm not sure if the BIOS should configure/enable it,
it is likely that none of your devices are using MSIs.

The solution:  My understanding is that AMD provides vendors with CIMX
code for providing the same standard NB interrupt configuration shown
in the BIOS guide, which does a far, far better job of spreading out
the interrupts.  Apparently they are not calling that code.  They
should.  Plus, it would be helpful to give the GPP (x4 slot)
interrupts 1 or 2 dedicated SB pins, seeing as someone might put a
busy device there.

Funny thing is, if they enable the NB IOAPIC, the original 2nd IOAPIC
entry they just removed will be correct (suggesting they called some
of the CIMX code).

I would like to hear if they will make this or a similar correction.
