From 7fc16be815b8ff85f174fc93d67f82400da08120 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 9 Aug 2012 16:45:57 +0200 Subject: [PATCH] xen: flush queue when getting an event xen does not have a register that, when written, will cause can_receive to go from false to true. However, flushing the queue can be attempted whenever the front-end raises its side of the Xen event channel. There is a single event channel for tx and rx.
