fn enable_msi(pci_dev: &PciDevice, vector: u8) -> boolExpand description
Try to enable MSI on pci_dev with vector.
Returns true on success, false if MSI is not supported or
programming failed. On success the device will deliver interrupts
via MSI instead of legacy INTx.
ยงNote
This does not clear the INTx_DISABLE bit in the PCI command
register. The caller should set COMMAND.INTx_DISABLE after
enabling MSI to prevent the device from also asserting its legacy
interrupt pin.
