  • 487722cf2   watchdog: Get rid of MODULE_ALIAS_MISCDEV statements ... Browse Code »

    I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
    and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements.

    Either the device is enumerated and the driver already has a module
    alias (e.g. PCI, USB etc.) that will get the right driver loaded
    automatically.

    Or the device is not enumerated and loading its driver will lead to
    more or less intrusive hardware poking. Such hardware poking should be
    limited to a bare minimum, so the user should really decide which
    drivers should be tried and in what order. Trying them all in
    arbitrary order can't do any good.

    On top of that, loading that many drivers at once bloats the kernel
    log. Also many drivers will stay loaded afterward, bloating the output
    of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets
    loaded as a dependency) can't even be unloaded!

    If defining char-major-10-130 is needed then it should happen in
    user-space.

  • 712b6aa87   intel_mid: Renamed *mrst* to *intel_mid* ... Browse Code »

    mrst is used as common name to represent all intel_mid type
    soc's. But moorsetwon is just one of the intel_mid soc. So
    renamed them to use intel_mid.

    This patch mainly renames the variables and related
    functions that uses *mrst* prefix with *intel_mid*.

    To ensure that there are no functional changes, I have compared
    the objdump of related files before and after rename and found
    the only difference is symbol and name changes.

  • 05454c26e   intel_mid: Renamed *mrst* to *intel_mid* ... Browse Code »

    Following files contains code that is common to all intel mid
    soc's. So renamed them as below.

    mrst/mrst.c -> intel-mid/intel-mid.c
    mrst/vrtc.c -> intel-mid/intel_mid_vrtc.c
    mrst/early_printk_mrst.c -> intel-mid/intel_mid_vrtc.c
    pci/mrst.c -> pci/intel_mid_pci.c

    Also, renamed the corresponding header files and made changes
    to the driver files that included these header files.

    To ensure that there are no functional changes, I have compared
    the objdump of renamed files before and after rename and found
    that the only difference is file name change.

    Trying to build the Intel SCU Watchdog fails for me with gcc 4.6.0 -
    $ gcc --version | head -n 1
    gcc (GCC) 4.6.0 20110513 (prerelease)

    like this :

  • 57539c1cf   watchdog: Intel SCU Watchdog Timer Driver for Moorestown and Medfield platforms. ... Browse Code »

    This submission includes:
    - Fix to intel_scu_write() to start watchdog timer the on the
    first write, and refresh on subsequent writes.
    This enables Open, write, write, ... usage model.
    - Moves boot parameter checks from intel_scu_open() to
    intel_scu_watchdog_init(), so driver init will fail if these
    parameters are out of bounds.
    - Adds check for whether process waiting in wait_event_interruptible()
    received a signal while it was waiting.
    - Other small error handling changes.

    Removed the read() method for now as that wass a non-standard behaviour.
