容易发现气瓶中的 lo
原标题:easy way to detect infinite loop in kernel of the linux

我只花了2个额外时间,试图在我修改lin子时找到灯塔,每当我把模块与油轮连接在一起时,我就好了,但是,如果我没有联系,我停止了工作,因此,利用我在fin中发现的印刷机,我的问题是,有些人知道探测这些 b的冰技术,有时很难找到这种 lo子,而且气球变得不可预测,>><<<>>>>”。

最佳回答

煤油中有一些基础设施使你能够发现一些锁定条件:

CONFIG_DETECT_SOFTLOCKUP

CONFIG_DETECT_HUNG_TASK

您可在“Kernel Hacking中找到各种24小时检查功能。

问题回答

我总是认为,正如你所做的那样,印刷机是有用的。

Other options would be running your kernel in Bochs in debugging mode. And as I recall, there s a way of running the kernel in gdb. Google can help with those options.


Oh, you said "avoid" not "debug"... hmm, the best way to avoid is do not hack the kernel :^)

很严重的是,在精心策划方案时,你必须小心谨慎。 添加一条主要()法,强调在添加起轨器之前测试你在使用方位的例行做法。 并且读过你的法典,特别是在你将ug子孤立到某一节之后。 我曾经发现过LynxOS终端司机的 lo,当时,一些ANSI艺术公司 h动了操作系统。 一些初级方案管理员显然撰写了这一部分,将越狱程序作为案文而不是编号。 守则非常糟糕,我gust笑地试图找到造成抢劫的准确错误,只是把大部分司机rew。 在加添油罐头之前,用手法测试了它。
