EEH on non-ppc platforms?

[<Sathya.Perla@xxxxxxxxxx>]

Hi, I'd like to know why the EEH feature of the Linux PCI sub-system is available only for ppc based pseries platform (I see the eeh core files only under arch/powerpc/platforms/pseries.) Aren't there any other platforms (say non-ppc based) with EEH-aware PCI bridges, on which this feature can be used?

Also, is it possible for a driver to independently detect a card error and request (via EEH) the PCI controller to freeze the slot? Is there a kernel API to do so? This is useful in cases where an (unrecoverable) card error may not be detected by the PCI controller.

thanks,
