    Subject[PATCH 03/12] SFI: document boot param "sfi=off"
    From: Feng Tang <>

    "sfi=off" is analogous to "acpi=off"

    In practice, "sfi=off" isn't likely to be very useful, for
    1. SFI is used only when ACPI is not available
    2. Today's SFI systems are not legacy PC-compatible

    ie. "sfi=off" on an ACPI-platform is a NO-OP,
    and "sfi=off" on an SFI-platform will likely result in boot failure.
