Hi Sarah, This patch supports xHCI MSI/MSI-X for xHCI controller. Changelog from V3: - Fixed the Oops message issue when system does not support MSI/MSI-X and fall back to Legacy INTx. By default,register the xhci->driver->irq to be xhci_irq(). When successfully enable msi/msi-x, disable legacy INTx by calling free_irq.
