available. As with MSI interrupts these can be disabled by setting
hw.usb.xhci.msix to 0 in the loader.
MSI-X interrupts are needed on some hardware, for example the Cavium
ThunderX only supports them, and with this we don't fall back to polling.

There is an issue with interrupts at the moment, but it works with
polling mode set (hw.usb.xhci.use_polling=1).

instead of only once during initialization. In r276717, reading the first
couple of registers in question already had been moved as a prerequisite
for the changes in that revision.

of the device and pass it through to the guest.
In the common case where there are no competing drivers for USB controllers
this change is a no-op.

- Simplify MSI allocation to what is actually needed for a single one.
- Release the MSI and the corresponding bus resource as appropriate when
either the interrupt resource cannot be allocated or setting up the
interrupt fails.
- Error out when interrupt allocation or setup fails and polling is
disabled.
- Release the MSI after the corresponding bus resource so the former is
not leaked on detach.
- Remove a redundant softc member.

interface is also backwards compatible to USB2.0 and USB1.0 and will

There will be follow-up commits during the coming week to link the
driver into the default kernel build and add missing USB3.0
functionality in the USB core. Currently only the driver files are
committed.
