C++ (Cpp) vtpci_config_intr Beispiele

Beispiel #1

static int
vtpci_legacy_intr(void *xsc)
{
	struct vtpci_softc *sc;
	struct vtpci_virtqueue *vqx;
	int i;
	uint8_t isr;

	sc = xsc;
	vqx = &sc->vtpci_vqx[0];

	/* Reading the ISR also clears it. */
	isr = vtpci_read_config_1(sc, VIRTIO_PCI_ISR);

	if (isr & VIRTIO_PCI_ISR_CONFIG)
		vtpci_config_intr(sc);

	if (isr & VIRTIO_PCI_ISR_INTR)
		for (i = 0; i < sc->vtpci_nvqs; i++, vqx++)
			virtqueue_intr(vqx->vq);

	return (isr ? FILTER_HANDLED : FILTER_STRAY);
}
