  • sfi_acpi.c needs to include linux/sysfs.h for data types.

    drivers/sfi/sfi_core.h:66: error: field 'attr' has incomplete type
    drivers/sfi/sfi_acpi.c:179: warning: 'struct kobject' declared inside parameter list
    drivers/sfi/sfi_acpi.c:179: warning: its scope is only this definition or declaration, which is probably not what you want
    drivers/sfi/sfi_acpi.c:182: warning: type defaults to 'int' in declaration of '__mptr'
    drivers/sfi/sfi_acpi.c:182: warning: initialization from incompatible pointer type

  • Analogous to ACPI's /sys/firmware/acpi/tables/...

    create /sys/firmware/sfi/tables/

    The tables are primariy for the kernel,
    but sometimes it is useful for user-space to be
    able to read them.

  • There are 2 major changes from v0.81 to v0.7:
    1. Consolidating the SPIB/I2CB tables into a new DEVS table,
    which is more expandable and can support other bus types
    than spi/i2c.
    2. Creating a new GPIO table, which list all the GPIO pins
    used in the platform.

    However, to avoid breaking current platforms who use SFI v0.7
    version firmware, the definitions for SPIB/I2CB will still
    be kept for a while

  • sfi_verify_table() is called at runtime, and thus cannot be __init

  • The function sfi_map_memory/sfi_unmap_memory uses
    early_ioremap/early_iounmap respectively, which refers to a __init
    function. And function sfi_check_table also refers to a __init function
    sfi_verify_table. Since the references are valid, so use __ref to get rid
    of the warnings.

    We were warned by the following warnings:

    LD vmlinux.o
    MODPOST vmlinux.o
    WARNING: vmlinux.o(.text+0xb6ba3a): Section mismatch in reference from
    the function sfi_map_memory() to the function
    .init.text:early_ioremap()
    The function sfi_map_memory() references
    the function __init early_ioremap().
    This is often because sfi_map_memory lacks a __init
    annotation or the annotation of early_ioremap is wrong.

    WARNING: vmlinux.o(.text+0xb6bab6): Section mismatch in reference from
    the function sfi_unmap_memory() to the function
    .init.text:early_iounmap()
    The function sfi_unmap_memory() references
    the function __init early_iounmap().
    This is often because sfi_unmap_memory lacks a __init
    annotation or the annotation of early_iounmap is wrong.

    WARNING: vmlinux.o(.text+0xb6be30): Section mismatch in reference from
    the function sfi_check_table() to the function
    .init.text:sfi_verify_table()
    The function sfi_check_table() references
    the function __init sfi_verify_table().
    This is often because sfi_check_table lacks a __init
    annotation or the annotation of sfi_verify_table is wrong.

  • Extend SFI to access standard ACPI tables.
    (eg. the PCI MCFG) using sfi_acpi_table_parse().

    Note that this is _not_ a hybrid ACPI + SFI mode.
    The platform boots in either ACPI mode or SFI mode.

    SFI runs only with acpi_disabled=1, which can be set
    at build-time via CONFIG_ACPI=n, or at boot time by
    the failure to find ACPI platform support.

    So this extension simply allows SFI-platforms to
    re-use existing standard table formats that happen to
    be defined to live in ACPI envelopes.

  • drivers/sfi/sfi_core.c contains the generic SFI implementation.
    It has a private header, sfi_core.h, for its own use and the
    private use of future files in drivers/sfi/

  • CONFIG_SFI=y enables the kernel to boot and run optimally
    on platforms that support the Simple Firmware Interface.

    Thanks to Jacob Pan for prototyping the initial Linux SFI support,
    and to Feng Tang for Linux bring-up and debug both in emulation
    and on Moorestown hardware.

    See http://simplefirmware.org for more information on SFI.
