I believe that the OLPC XO1 does not run in ACPI mode and thus does not use the ACPI EC driver to talk to the EC on their board. Presumably they use some native embedded controller driver to talk to their platform specific embedded controller. I don't know why they call their interrupt an SCI. Per above, it can't be an ACPI SCI. Presumably they call it that b/c their chipset documentation calls it that too, on the (invalid) assumption that an ACPI-enabled OS and firmware would be running on the hardware. Please let me know if I'm wrong. -Len - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
