  • ce8c628ab   dmi-id: fix for __you_cannot_kmalloc_that_much failure ... Browse Code »

    gcc 3.2 has a hard time coping with the code in dmi_id_init():

    drivers/built-in.o(.init.text+0x789e): In function `dmi_id_init':
    : undefined reference to `__you_cannot_kmalloc_that_much'
    make: *** [.tmp_vmlinux1] Error 1

    Moving half of the code to a separate function seems to help. This is a
    no-op for gcc 4.1 which will successfully inline the code anyway.

    get rid of input BIT* duplicate defines

    use newly global defined macros for input layer. Also remove includes of
    input.h from non-input sources only for BIT macro definiton. Define the
    macro temporarily in local manner, all those local definitons will be
    removed further in this patchset (to not break bisecting).

    We can use sysfs attributes with an extra parameter for dmi id

  • 7eff2e7a8   Driver core: change add_uevent_var to use a struct ... Browse Code »

    This changes the uevent buffer functions to use a struct instead of a
    long list of parameters. It does no longer require the caller to do the
    proper buffer termination and size accounting, which is currently wrong
    in some places. It fixes a known bug where parts of the uevent
    environment are overwritten because of wrong index calculations.

    Many thanks to Mathieu Desnoyers for finding bugs and improving the
    error handling.

  • 1855256c4   drivers/firmware: const-ify DMI API and internals ... Browse Code »

    Three main sets of changes:

    1) dmi_get_system_info() return value should have been marked const,
    since callers should not be changing that data.

    2) const-ify DMI internals, since DMI firmware tables should,
    whenever possible, be marked const to ensure we never ever write to
    that data area.

    3) const-ify DMI API, to enable marking tables const where possible
    in low-level drivers.

    And if we're really lucky, this might enable some additional
    optimizations on the part of the compiler.

    The bulk of the changes are #2 and #3, which are interrelated. #1 could
    have been a separate patch, but it was so small compared to the others,
    it was easier to roll it into this changeset.

  • 18a8bd949   serial: convert early_uart to earlycon for 8250 ... Browse Code »

    Beacuse SERIAL_PORT_DFNS is removed from include/asm-i386/serial.h and
    include/asm-x86_64/serial.h. the serial8250_ports need to be probed late in
    serial initializing stage. the console_init=>serial8250_console_init=>
    register_console=>serial8250_console_setup will return -ENDEV, and console
    ttyS0 can not be enabled at that time. need to wait till uart_add_one_port in
    drivers/serial/serial_core.c to call register_console to get console ttyS0.
    that is too late.

    Make early_uart to use early_param, so uart console can be used earlier. Make
    it to be bootconsole with CON_BOOT flag, so can use console handover feature.
    and it will switch to corresponding normal serial console automatically.

    new command line will be:
    console=uart8250,io,0x3f8,9600n8
    console=uart8250,mmio,0xff5e0000,115200n8
    or
    earlycon=uart8250,io,0x3f8,9600n8
    earlycon=uart8250,mmio,0xff5e0000,115200n8

    it will print in very early stage:
    Early serial console at I/O port 0x3f8 (options '9600n8')
    console [uart0] enabled
    later for console it will print:
    console handover: boot [uart0] -> real [ttyS0]

  • 91a690295   sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes ... Browse Code »

    Well, first of all, I don't want to change so many files either.

    What I do:
    Adding a new parameter "struct bin_attribute *" in the
    .read/.write methods for the sysfs binary attributes.

    In fact, only the four lines change in fs/sysfs/bin.c and
    include/linux/sysfs.h do the real work.
    But I have to update all the files that use binary attributes
    to make them compatible with the new .read and .write methods.
    I'm not sure if I missed any. :(

    Why I do this:
    For a sysfs attribute, we can get a pointer pointing to the
    struct attribute in the .show/.store method,
    while we can't do this for the binary attributes.
    I don't know why this is different, but this does make it not
    so handy to use the binary attributes as the regular ones.
    So I think this patch is reasonable. :)

    Who benefits from it:
    The patch that exposes ACPI tables in sysfs
    requires such an improvement.
    All the table binary attributes share the same .read method.
    Parameter "struct bin_attribute *" is used to get
    the table signature and instance number which are used to
    distinguish different ACPI table binary attributes.

    Without this parameter, we need to offer different .read methods
    for different ACPI table binary attributes.
    This is impossible as there are various ACPI tables on different
    platforms, and we don't know what they are until they are loaded.

  • 7b595756e   sysfs: kill unnecessary attribute->owner ... Browse Code »

    sysfs is now completely out of driver/module lifetime game. After
    deletion, a sysfs node doesn't access anything outside sysfs proper,
    so there's no reason to hold onto the attribute owners. Note that
    often the wrong modules were accounted for as owners leading to
    accessing removed modules.

    This patch kills now unnecessary attribute->owner. Note that with
    this change, userland holding a sysfs node does not prevent the
    backing module from being unloaded.

    For more info regarding lifetime rule cleanup, please read the
    following message.

  • 4f5c791a8   DMI-based module autoloading ... Browse Code »

    The patch below adds DMI/SMBIOS based module autoloading to the Linux
    kernel. The idea is to load laptop drivers automatically (and other
    drivers which cannot be autoloaded otherwise), based on the DMI system
    identification information of the BIOS.

    Right now most distros manually try to load all available laptop
    drivers on bootup in the hope that at least one of them loads
    successfully. This patch does away with all that, and uses udev to
    automatically load matching drivers on the right machines.

    Basically the patch just exports the DMI information that has been
    parsed by the kernel anyway to userspace via a sysfs device
    /sys/class/dmi/id and makes sure that proper modalias attributes are
    available. Besides adding the "modalias" attribute it also adds
    attributes for a few other DMI fields which might be useful for
    writing udev rules.

    This patch is not an attempt to export the entire DMI/SMBIOS data to
    userspace. We already have "dmidecode" which parses the complete DMI
    info from userspace. The purpose of this patch is machine model
    identification and good udev integration.

    To take advantage of DMI based module autoloading, a driver should
    export one or more MODULE_ALIAS fields similar to these:

    MODULE_ALIAS("dmi:*:svnMICRO-STARINT'LCO.,LTD:pnMS-1013:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*");
    MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1058:pvr0581:rvnMSI:rnMS-1058:*:ct10:*");
    MODULE_ALIAS("dmi:*:svnMicro-StarInternational:pnMS-1412:*:rvnMSI:rnMS-1412:*:cvnMICRO-STARINT'LCO.,LTD:ct10:*");
    MODULE_ALIAS("dmi:*:svnNOTEBOOK:pnSAM2000:pvr0131*:cvnMICRO-STARINT'LCO.,LTD:ct10:*");

    These lines are specific to my msi-laptop.c driver. They are basically
    just a concatenation of a few carefully selected DMI fields with all
    potentially bad characters stripped.

    Besides laptop drivers, modules like "hdaps", the i2c modules
    and the hwmon modules are good candidates for "dmi:" MODULE_ALIAS
    lines.

    Besides merely exporting the DMI data via sysfs the patch adds
    support for a few more DMI fields. Especially the CHASSIS fields are
    very useful to identify different laptop modules. The patch also adds
    working MODULE_ALIAS lines to my msi-laptop.c driver.

    I'd like to thank Kay Sievers for helping me to clean up this patch
    for posting it on lkml.

    Patch is against Linus' current GIT HEAD. Should probably apply to
    older kernels as well without modification.

  • 496a0fc8c   [PATCH] Fix race in efi variable delete code ... Browse Code »

    Fix race when deleting an EFI variable and issuing another EFI command on
    the same variable. The removal of the variable from the efivars_list
    should be done in efivar_delete and not delayed until the kobject release.

    Furthermore, remove the item from the list at module unload time, and use
    list_for_each_entry_safe() rather than list_for_each_safe() for
    readability.

    Tested on ia64.
