  • 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.

    The DEFINE_DMI_ATTR macro has a single user left so we can expand it
    for slightly shorter/simpler code.

  • 637447566   dmi-id: Use dynamic sysfs attributes ... Browse Code »

    We can use sysfs attributes with an extra parameter for dmi id
    attributes. This makes it possible to use the same callback function
    for all attributes, reducing the binary size significantly (-18% on
    x86_64.)

  • 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.

  • 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.
