Subject: [PATCH v2 3/3] In DM_LOWEST, only deliver interrupts to vcpus with enabled LAPIC's
Date: Mon, 14 Jun 2010 13:11:22 -0400 [thread overview]
Message-ID: <1276535482-11965-4-git-send-email-clalance@redhat.com> (raw)
In-Reply-To: <1276535482-11965-1-git-send-email-clalance@redhat.com>
Otherwise we might try to deliver a timer interrupt to a cpu that
can't possibly handle it.
