[Qemu-devel] [PATCH v2] usb: move ehci_create_ich9_with_companions to hw/i386
Posted by Paolo Bonzini 5 years, 4 months ago
This function is only needed when Q35 is in use.  Moving it to
the same file that uses it lets you disable the entire USB
subsystem in x86_64-softmmu.mak; of course doing that will
cause -usb to break horribly, but one thing at a time.
