John Baldwin 1925586e03 Honor the disabled setting for MSI-X interrupts for passthrough devices. ... Add a new ioctl to disable all MSI-X interrupts for a PCI passthrough device and invoke it if a write to the MSI-X capability registers disables MSI-X. This avoids leaving MSI-X interrupts enabled on the host if a guest device driver has disabled them (e.g. as part of detaching a guest device driver). This was found by Chelsio QA when testing that a Linux guest could switch from MSI-X to MSI interrupts when using the cxgb4vf driver. While here, explicitly fail requests to enable MSI on a passthrough device if MSI-X is enabled and vice versa.
