I need to disable a CONFIG_STRICT_DEVMEM option in my Linux kernel and recompile it. Why? I was told to do so. I know I can disable it by simply commenting it out in the .config file, but I need to see how it is done through make menuconfig or make nconfig. Why? This is for a demo and I need to be able to show it. Does anyone know how to do it?

推荐答案

如果您不了解菜单配置的方式，请按/进行搜索(输入vim和朋友)，然后输入足够的配置选项来缩小范围，例如"strict_devmem"或仅仅是"devmem".然后，您可以点击括号中的数字之一，直接跳至相关菜单.当您需要检查一大堆随机选项时(例如，使您拥有的开发defconfig可以很好地与systemd文件系统配合使用)，这绝对是一个救命稻草.

If you don't know your way around menuconfig, hit / to search (à la vim and friends), and type in enough of the config option to narrow it down, e.g. "strict_devmem" or just "devmem". You can then hit one of the numbers in parentheses to jump straight to the relevant menu. It's an absolute lifesaver when you need to check on a whole bunch of random options (e.g. making whatever development defconfig you've got play nicely with a systemd filesystem).

在这种情况下，它应该在内核黑客"下作为对/dev/mem的过滤器访问"提供.

In this specific case, it should be available under "kernel hacking" as "filter access to /dev/mem".
