H A D | hcd-xhci.c | f1f8bc21 Fri Nov 08 10:43:20 GMT 2013 Gerd Hoffmann <kraxel@redhat.com> xhci: add support for suspend/resume
The OS can ask the xhci controller to save and restore its internal state, which is used by the OS when the system is suspended and resumed.
This patch handles writes to the save + restore bits in the command register. Only thing it does is updating the restore error bit in the status register to signal an error on restore. The guest OS should do a full reinitialization after resume then.
This is the minimal patch which gets S3 going with xhci. Implementing full save/restore support is TBD.
