C++ (Cpp) pvscsi_scan_target Examples

Example #1

static void
init_pvscsi(void *data)
{
    struct pci_device *pci = data;
    void *iobase = pci_enable_membar(pci, PCI_BASE_ADDRESS_0);
    if (!iobase)
        return;
    pci_enable_busmaster(pci);

    dprintf(1, "found pvscsi at %pP, io @ %p\n", pci, iobase);

    pvscsi_write_cmd_desc(iobase, PVSCSI_CMD_ADAPTER_RESET, NULL, 0);

    struct pvscsi_ring_dsc_s *ring_dsc = NULL;
    pvscsi_init_rings(iobase, &ring_dsc);
    int i;
    for (i = 0; i < 7; i++)
        pvscsi_scan_target(pci, iobase, ring_dsc, i);
}
