Subject: [Qemu-devel] [PATCH 2/8] xhci: decouple EV_QUEUE from TD_QUEUE
Date: Tue, 27 Sep 2016 10:32:46 +0200 [thread overview]
Message-ID: <1474965172-30321-3-git-send-email-kraxel@redhat.com> (raw)
In-Reply-To: <1474965172-30321-1-git-send-email-kraxel@redhat.com>
EV_QUEUE must not change because an array of that size is part of live
migration data. Hard-code current value there, so we can touch TD_QUEUE
without breaking live migration.
