  • 06efbeb4a   hp_accel: fix race in device removal ... Browse Code »

    The work queue has to be flushed after the device has been made
    inaccessible. The patch closes a window during which a work queue might
    remain active after the device is removed and would then lead to ACPI
    calls with undefined behavior.

  • a03018ff7   lis3: better support for hp 6730x ... Browse Code »

    I have learned that the 6730b and 6730s have different accelerometer
    orientation, and have modified the driver accordingly (diff attached),
    while dropping the wild guess for AMD based 6735 having the same
    orientation as Intel based 6730 (this is not true for any other related
    series/family, thus is not probable for 673x).

    Now that there is no need to hookup on the open/close of the joystick,
    it's possible to use the simplified interface input_polled_device, instead
    of creating our own kthread.

  • a002ee896   lis3: remove automatic shutdown of the device ... Browse Code »

    After measurement on my laptop, it seems that turning off the device does
    not bring any energy saving (within 0.1W precision). So let's keep the
    device always on. It simplifies the code, and it avoids the problem of
    reading a wrong value sometimes just after turning the device on.

    Moreover, since commit ef2cfc790bf5f0ff189b01eabc0f4feb5e8524df had been
    too zealous, the device was actually never turned off anyway. This patch
    also restores the damages done by this commit concerning the
    initialisation/poweroff.

    Also do more clean up with the usage of the lis3_dev global variable.

  • a38da2ed7   lis3: solve dependency between core and ACPI ... Browse Code »

    This solves the dependency between lis3lv02d.[ch] and ACPI specific
    methods. It introduces a ->bus_priv pointer to the device struct which is
    casted to 'struct acpi_device' in the ACIP layer. Changed hp_accel.c
    accordingly.

  • 12a324b6a   hp_accel: axis conversion for hp compaq 8710w ... Browse Code »

    I have a laptop HP Compaq 8710W, I compiled into my kernel the LIS3LV02DL
    and HP_ACCEL module drivers. While loading it cannot recognize the laptop
    model, so i am sending the necessary information to update the database of
    axis orientations.

    >When the laptop is horizontal the position reported is about 0 for X and Y
    >and a positive value for Z
    Yes, it is about 0,0,1000, the actual reading says: (-17,-26,1018);

    > If the left side is elevated, X increases (becomes positive)
    Yes, X goes toward to positive 1000.

    >If the front side (where the touchpad is) is elevated, Y decreases (becomes negative)
    No, Y goes toward to positive 1000.

    >If the laptop is put upside-down, Z becomes negative
    Yes, the laptop on a table Z gives 1000, and if upsidedown the Z reads
    -1000.

    So in few words the Y axis is inverted.

    Add support for HP Pavilion dv5.

    Since Intel-based models have an inverted x axis, while AMD-based models
    have an inverted y axis, we introduce a new macro that special-cases axis
    orientation based on two DMI entries: HP dv5 axis configuration is then
    based on both the PRODUCT and BOARD name.

  • 137bad323   lis3lv02d: support both one- and two-byte sensors ... Browse Code »

    Sensors responding with 0x3B to WHO_AM_I only have one data register per
    direction, thus returning a signed byte from the position which is
    occupied by the MSB in sensors responding with 0x3A.

    Since multiple sensors share the reply to WHO_AM_I, we rename the defines
    to better indicate what they identify (family of single and double
    precision sensors).

    We support both kind of sensors by checking for the sensor type on init
    and defining appropriate data-access routines and sensor limits (for the
    joystick) depending on what we find.

  • ef2cfc790   hp accelerometer: add freefall detection ... Browse Code »

    This adds freefall handling to hp_accel driver. According to HP, it
    should just work, without us having to set the chip up by hand.

    hpfall.c is example .c program that parks the disk when accelerometer
    detects free fall. It should work; for now, it uses fixed 20seconds
    protection period.

    The LED on HP notebooks is connected through ACPI. That unfortunately
    means that it needs to be delayed by using schedule_work() to avoid
    calling the ACPI interpreter from an invalid context.

  • 9e0c79782   lis3lv02d: merge with leds hp disk ... Browse Code »

    Move the second part of the HP laptop disk protection functionality (a red
    led) to the same driver. From a purely Linux developer's point of view,
    the led and the accelerometer have nothing related. However, they
    correspond to the same ACPI functionality, and so will always be used
    together, moreover as they share the same ACPI PNP alias, there is no
    other simple to allow to have same loaded at the same time if they are not
    in the same module. Also make it requires the led class to compile and
    update the Kconfig text.

  • cfce41a6d   LIS3LV02D: separate the core from HP ACPI API ... Browse Code »

    The sensor can be accessed via various buses. In particular, SPI, I²C
    and, on HP laptops, via a specific ACPI API (the only one currently
    supported). Separate this latest platform from the core of the sensor
    driver to allow support for the other bus type. The second, and more
    direct goal is actually to be able to merge this part with the
    hp-disk-leds driver, which has the same ACPI PNP number.
