  • a81b67dac   hwmon: (pc87427) use permission-specific DEVICE_ATTR variants ... Browse Code »

    Use DEVICE_ATTR_RO for read-only attributes. This simplifies the source
    code, improves readbility, and reduces the chance of inconsistencies.

    The conversion was done automatically using coccinelle. It was validated
    by compiling both the old and the new source code and comparing its text,
    data, and bss size.

  • 86855b0c1   hwmon: Use resource_size ... Browse Code »

    Use the function resource_size, which reduces the chance of introducing
    off-by-one errors in calculating the resource size.

    The semantic patch that makes this change is as follows:
    (http://www.emn.fr/x-info/coccinelle/)

    //
    @@
    struct resource *res;
    @@

    - (res->end - res->start) + 1
    + resource_size(res)

  • b9acb64a3   hwmon: Check for ACPI resource conflicts ... Browse Code »

    Check for ACPI resource conflicts in hwmon drivers. I've included
    all Super-I/O and PCI drivers.

    I've voluntarily left out:
    * Vendor-specific drivers: if they conflicted on any system, this would
    pretty much mean that they conflict on all systems, and we would know
    by now.
    * Legacy ISA drivers (lm78 and w83781d): they only support chips found
    on old designs were ACPI either wasn't supported or didn't deal with
    thermal management.
    * Drivers accessing the I/O resources indirectly (e.g. through SMBus):
    the checks are already done where they belong, i.e. in the bus drivers.

  • 67b671bce   hwmon: Let the user override the detected Super-I/O device ID ... Browse Code »

    While it is possible to force SMBus-based hardware monitoring chip
    drivers to drive a not officially supported device, we do not have this
    possibility for Super-I/O-based drivers. That's unfortunate because
    sometimes newer chips are fully compatible and just forcing the driver
    to load would work. Instead of that we have to tell the users to
    recompile the kernel driver, which isn't an easy task for everyone.

    So, I propose that we add a module parameter to all Super-I/O based
    hardware monitoring drivers, letting advanced users force the driver
    to load on their machine. The user has to provide the device ID of a
    supposedly compatible device. This requires looking at the source code or
    a datasheet, so I am confident that users can't randomly force a driver
    without knowing what they are doing. Thus this should be relatively safe.

    As you can see from the code, the implementation is pretty simple and
    unintrusive.

  • 04a6217df   hwmon: Fix a potential race condition on unload ... Browse Code »

    Fix a potential race condition when some hardware monitoring platform
    drivers are being unloaded. I believe that the driver data pointer
    shouldn't be cleared before all the sysfs files are removed, otherwise
    a sysfs callback might attempt to dereference a NULL pointer. I'm not
    sure exactly what the driver core protects drivers against, so let's
    play it safe.

    While we're here, clear the driver data pointer when probe fails, so
    as to not leave an invalid pointer behind us.

  • ce7ee4e80   hwmon: Request the I/O regions in platform drivers ... Browse Code »

    My understanding of the resource management in the Linux 2.6 device
    driver model is that the devices should declare their resources, and
    then when a driver attaches to a device, it should request the
    resources it will be using, so as to mark them busy. This is how the
    PCI and PNP subsystems work, you can clearly see the two levels of
    resources (declaration and request) in /proc/ioports for these
    devices.

    So I believe that our platform hardware monitoring drivers should
    follow the same logic. At the moment, we only declare the resources
    but we do not request them. This patch adds the I/O region request
    and release calls.

  • ba224e2c4   hwmon: New PC87427 hardware monitoring driver ... Browse Code »

    This is a new hardware monitoring driver for the National Semiconductor
    PC87427 Super-I/O chip. It only supports fan speed monitoring for now,
    while the chip can do much more.

    Thanks to Amir Habibi at Candelis for setting up a test system, and to
    Michael Kress for testing several iterations of this driver.
