  • 268e2519f   dmaengine: ioatdma: Add intr_coalesce sysfs entry ... Browse Code »

    We observed performance increase with DMA copy from memory
    to MMIO by changing the interrupt coalescing value to 0.
    The previous set value was projected on the C5xxx Xeon
    platform and no longer holds true. Removing hard coded
    value and providing a tune-able in sysfs in order to allow
    user to tune this on a per channel basis. By default this
    value will be set to 0.
    Example of sysfs variable importing for interrupt coalescing
    value from command line:
    echo 5> /sys/devices/pci0000:00/0000:00:04.0/dma/dma0chan0/
    quickdata/intr_coalesce
