From ac61a7579625ddfca3b2e0aa298879a94d15884d Mon Sep 17 00:00:00 2001 From: Vegard Nossum Date: Fri, 27 Feb 2009 11:35:55 +0100 Subject: kmemcheck: add opcode self-testing at boot We've had some troubles in the past with weird instructions. This patch adds a self-test framework which can be used to verify that a certain set of opcodes are decoded correctly. Of course, the opcodes which are not tested can still give the wrong results. In short, this is just a safeguard to catch unintentional changes in the opcode decoder. It does not mean that errors can't still occur!
