Subject: [PATCH 09/41] KVM: Remove the 'emulated' field from the userspace interface
Date: Sun,  1 Apr 2007 17:35:06 +0300	[thread overview]
Message-ID: <1175438139494-git-send-email-avi@qumranet.com> (raw)
In-Reply-To: <1175438139242-git-send-email-avi@qumranet.com>

We no longer emulate single instructions in userspace.  Instead, we service
mmio or pio requests.
