My 5 /proc/cpuinfos say: Genuine Intel(R) CPU T2500 @ 2.00GHz Intel(R) Xeon(TM) CPU 3.00GHz Intel(R) Xeon(R) CPU E5335 @ 2.00GHz Intel(R) Xeon(TM) CPU 2.80GHz Intel(R) Xeon(R) CPU X5482 @ 3.20GHz I'm not sure if that's any more helpful :-) Especially the first one. I don't think of my laptop as having a T2500. I think of it as having a 32-bit Core Duo. And I have no idea what the different types of Xeon are. But then, I couldn't tell you whether they are Nehalems or Penryns either, and I'm quite sure the owners couldn't either. $ grep name /proc/cpuinfo model name : QEMU Virtual CPU version 0.9.1 If only they were all so clear :-) -- Jamie From mboxrd@z Thu Jan 1 00:00:00 1970 Received: from mailman by lists.gnu.org with tmda-scanned (Exim 4.43) id 1NXPXL-0001ZQ-PU for qemu-devel@nongnu.org; Tue, 19 Jan 2010 20:39:11 -0500 Received: from exim by lists.gnu.org with spam-scanned (Exim 4.43) id 1NXPXH-0001Sn-8r for qemu-devel@nongnu.org; Tue, 19 Jan 2010 20:39:11 -0500 Received: from [199.232.76.173] (port=57149 helo=monty-python.gnu.org) by lists.gnu.org with esmtp (Exim 4.43) id 1NXPXH-0001Sb-0s for qemu-devel@nongnu.org; Tue, 19 Jan 2010 20:39:07 -0500 Received: from mail2.shareable.org ([80.68.89.115]:47466) by monty-python.gnu.org with esmtps (TLS-1.0:RSA_AES_256_CBC_SHA1:32) (Exim 4.60) (envelope-from ) id 1NXPXG-0006bc-KF for qemu-devel@nongnu.org; Tue, 19 Jan 2010 20:39:06 -0500 Date: Wed, 20 Jan 2010 01:38:49 +0000 From: Jamie Lokier Subject: Re: [Qemu-devel] [PATCH] Add definitions for current cpu models..
