pci-ioapic-0502.patch

Move PCI device scanning to dom0. Enable ACPI in dom0. This should greatly reduce the complexity of xen and move the complexity of dealing with hardware bugs and workarounds etc to dom0.

The ioapic local apic (and hence all the vectors) are owned by the hypervisor. Dom0 enables the ACPI interpreter, handles PCI and ACPI based interrupt routing.

New hypercalls to assign vectors and for accessing the ioapic.

Functionality not yet provided:

o acpi=off to support machines with broken or no acpi support.
o support for driver domains

I've applied this patch on my T41p and am using it right now. Here are the results so far:

1) Everything builds and loads properly, the ibm_acpi drivers enables most of the /proc/acpi/ibm entries it's supposed to and they seem to work.
2) I get an oops during startup (doing USB coldplug), dmesg is attached
3) I don't seem to be getting proper battery status (it's always being reported as 0%)

This work looks really promising. Thanks :-)

Regards,
Anthony Liguori

Hi Anthony,

Do these two problems happen on the native i386 kernel built with the same source base? If they are reproducible on the native kernel, we should have linux-acpi folks look at it.

-Arun

No, they aren't. On a Vanilla 2.6.11 kernel with the same config (with the exception of the few Xen specific CONFIG options) these issues don't appear.

They appear reliably with the patch. Any suggestions on how I can get more information to help you out?

Regards,
Anthony Liguori

I'm getting one of these beasts (either a T41/T42) tomorrow. If you can send me your .config and runscript.sh, I'll try to reproduce it.

-Arun

I've entered a bug (#19) in bugzilla about it to contain the necessary files.

Regards,
Anthony Liguori

Hi!

Ah great! I've been looking forward to that patch for some time now :-) Unfortunately it isn't working on my machine. :-/

xen boots, but dom0 freezes while loading the sata-driver. It is the "silicon image" sata-driver from the scsi-section in kernel-config.
The system freezes after the line "applying Seagate errata fix" (there are some issuse between silicon image and seagate)

There exist another driver for that controller in the ATA-section. When using this driver the system does not freeze, but stops at sata-driver-loading as well.
But here after some time I get a "lost interrupt" message.

When booting without your patch the sata-controller uses irg 5 and shares it with 7 other pci-devices.
With your patch the controller uses irq 18, so io-apic is used.

The system is an amd duron with nforce2 chipset.

patrick

Did you have acpi=off by any chance? It'd be great if you can attach the
native dmesg and the dmesg with the patch into a bugzilla at:

http://bugzilla.xensource.com/

-Arun

I tryed that. Then the System boots well like without the patch.

I just did this. Its bug #23.
Feel free to contact me if you need more testing and logs.

Patrick

Hi!

Great! the system is booting now with ioapic enabled.

acpi=off does not work for me now.
The system boots, but then there are interrupt-timeouts from the sata and ethernet - controller.
should I open another bugreport?

And I have another problem, see new post for "physdev_dom0_hide" Maybe it has something to do with this patch, too?

Patrick

This is pretty much unsupportable -- if Xen has detected IOAPICs and started to initialise them, it is not really possible to go back to a full legacy PIC mode. If you want to boot 'acpi=off' then you need to add the 'ignorebiostables' option as a Xen boot parameter. This will prevent Xen from finding the IOAPIC and Xen+domain0 can both boot in blissful ignorance.

What is needed is 'acpi=' config option for Xen as well as XenLinux, and require the option to be set the same for both Xen and domain0 (we could enforce this at boot time by propagating the Xen parameter onto the domain0 command line). This is something I intend to implement after upgrading the apic/mpparse/acpi support in Xen to Linux-2.6 equivalent (it's all currently based on Linux-2.4 source files).

I haven't seen the post, but physdev_dom0_hide has had no effect since we applied the ACPI patch earlier this week. Currently we do not support device drivers outside domain0 (they have no way of safely accessing PCI space) so there is no point in supporting hiding of pci devices from dom0 anyway. :-)

Getting support for driver domains back is a priority for the 3.0 release.

-- Keir

If acpi=off implies ignorebiostables, then all checks for ignorebiostables should also check for acpi=off.
