◆ vxge_hw_device_begin_irq()

enum vxge_hw_status vxge_hw_device_begin_irq ( struct __vxge_hw_device * hldev )

vxge_hw_device_begin_irq - Begin IRQ processing.

@hldev: HW device handle.

The function performs two actions, It first checks whether (shared IRQ) the interrupt was raised by the device. Next, it masks the device interrupts.

Note: vxge_hw_device_begin_irq() does not flush MMIO writes through the bridge. Therefore, two back-to-back interrupts are potentially possible.

Returns: 0, if the interrupt is not "ours" (note that in this case the device remain enabled). Otherwise, vxge_hw_device_begin_irq() returns 64bit general adapter status.

◆ vxge_hw_vpath_doorbell_rx()

void vxge_hw_vpath_doorbell_rx ( struct __vxge_hw_ring * ring )

vxge_hw_vpath_doorbell_rx - Indicates to hw the qwords of receive descriptors posted.

@ring: Handle to the ring object used for receive

The function writes the number of qwords of rxds posted during replishment. Since the function is called frequently, a flush is not required to post the write transaction. At the very least, the previous write will be flushed once the subsequent write is made.

Returns: None.
