Subject: [PATCH 0/1] Prevent one cause of "MP-BIOS bug: 8254 timer"... message from linux
Date: Wed, 26 Feb 2014 13:00:46 -0500 [thread overview]
Message-ID: <1393437647-16694-1-git-send-email-dslutz@verizon.com> (raw)
Based on the proposed fix in QEMU:
http://marc.info/?l=qemu-devel&m=139304386331192&w=2
That was provided for:
http://marc.info/?l=qemu-devel&m=139295851107140&w=2
Which is very close to a bug I have been looking into and asked some
questions about in:
http://lists.xen.org/archives/html/xen-devel/2014-02/msg01787.html
I came up with this change. It does look like vpt does support
starting a timer in the past and what happens is based on the
setting of timer_mode. Since real hardware does not support this
and this is the simpler change I went this way.
