Date: Mon, 26 Jan 2009 19:54:31 +0000 [thread overview]
Message-ID: <E1LRXXT-0003ZJ-Gm@cvs.savannah.gnu.org> (raw)
Revision: 6452
http://svn.sv.gnu.org/viewvc/?view=rev&root=qemu&revision=6452
Author: aliguori

Log Message:
-----------
Log reset events (Jan Kiszka)
Original idea&code by Kevin Wolf, split-up in two patches and added more
archs.
This patch introduces a flag to log CPU resets. Useful for tracing
unexpected resets (such as those triggered by x86 triple faults).
