For example: The OLPC XO uses an x86 processor called the Geode. It supports a breakpoint that traps based on the opcode. For example, one could set it to trap on arpl instructions. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
