From 69e25d26b46a6e37698de4489eed5b07853bfe9e Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Sun, 13 Apr 2014 20:42:34 +1000 Subject: [PATCH] usb-ohci: Add vmstate descriptor This adds migration support for OHCI. This defines a descriptor for OHCIState. This changes some OHCIState field types to be migration compatible. This adds a descriptor for OHCIPort. This migrates the EOF timer if the USB was started at the time of migration.
