Do you have CONFIG_EEH set in your .config? I'm guessing not, and that
causes pci.h to not define pci_dev_to_eeh_dev().

Gavin, I think this is broken by your
39baadbf36cee3ede5fdb8a34006d9109e5e2570. Probably need a wrapper for
pci_dev_to_eeh_dev() when !CONFIG_EEH?

Actually, looking at it more, eeh_dev, which is protected by CONFIG_EEH
in arch/powerpc/include/asm/eeh.h won't be defined in such situations
and is the type of the return from pci_dev_to_eeh_dev(). So that's going
to be broken completely if !CONFIG_EEH as above.

So maybe the callers should be EEH-unaware (as they were before) and the
callee becomes of the EEH variety (at compile-time) if CONFIG_EEH is
set?

Thanks,
Nish

I think it's because iommu.c depends on CONFIG_EEH heavily anyway with
or without the fix 39baadbf36cee3ede5fdb8a34006d9109e5e2570. That means
without CONFIG_EEH, iommu.c won't work properly even it can be compiled
successfully :-)

The story behind is that the PCI device is expected to be PE sensitive.
While setting up its DMA (through IOMMU), the number of the PE to which
the PCI device belongs to is passed to the related RTAS call. So the
PE number of the PCI device is expected if possible. As I knew, the PE
number of the PCI device is -ONLY- figured out by EEH.

In order to make iommu.c irrelative to CONFIG_EEH, we might figure out
the PE number of the PCI device during PCI probe time. Here're some
rough thoughts about the rework.

	- Introduce additional field "int pe_num" to "struct dev_archdata".
	  That would be traced like: (struct pci_dev)->(struct device dev)
	  ->(struct dev_archdata archdata).
	- During the PCI probe time (maybe pci_fixup_early), we can figure
	  out the PE number.

Then we can retrieve the PE number of PCI device from "int pe_num" and needn't
care CONFIG_EEH has been turned on or off. I'm not sure Ben has any comments
on the idea? 

Thanks,
Gavin

In order to make iommu.c irrelative to CONFIG_EEH, we might figure out
the PE number of the PCI device during PCI probe time. Here're some
rough thoughts about the rework.

	- Introduce additional field "int pe_num" to "struct dev_archdata".
	  That would be traced like: (struct pci_dev)->(struct device dev)
	  ->(struct dev_archdata archdata).
	- During the PCI probe time (maybe pci_fixup_early), we can figure
	  out the PE number.

Then we can retrieve the PE number of PCI device from "int pe_num" and needn't
care CONFIG_EEH has been turned on or off. I'm not sure Ben has any comments
on the idea? 

Thanks,
Gavin

Just select EEH from pseries Kconfig, no point in keeping that a user visible option.

Cheers,
Ben.
