  • 43539c38c   [PATCH] htirq: allow buggy drivers of buggy hardware to write the registers ... Browse Code »

    This patch adds a variant of ht_create_irq __ht_create_irq that takes an
    aditional parameter update that is a function that is called whenever we want
    to write to a drivers htirq configuration registers.

    This is needed to support the ipath_iba6110 because it's registers in the
    proper location are not actually conected to the hardware that controlls
    interrupt delivery.

  • ec68307cc   [PATCH] htirq: refactor so we only have one function that writes to the chip ... Browse Code »

    This refactoring actually optimizes the code a little by caching the value
    that we think the device is programmed with instead of reading it back from
    the hardware. Which simplifies the code a little and should speed things up a
    bit.

    This patch introduces the concept of a ht_irq_msg and modifies the
    architecture read/write routines to update this code.

    There is a minor consistency fix here as well as x86_64 forgot to initialize
    the htirq as masked.

  • 95d77884c   [PATCH] htirq: tidy up the htirq code ... Browse Code »

    This moves the declarations for the architecture helpers into
    include/linux/htirq.h from the generic include/linux/pci.h. Hopefully this
    will make this distinction clearer.

    htirq.h is included where it is needed.

    The dependency on the msi code is fixed and removed.

    The Makefile is tidied up.
