以下是Linux Kernel Configuration 顶层目录
General setup (常规设置）
- Prompt for development and/or incomplete code/drivers （显示尚在开发中或尚未完成的代码与驱动.除非你是测试人员或者开发者,否则 请勿选择）
- Local version - append to kernel （在内核版本后面加上自定义的版本字符串(小于64字符),可以用"uname -a"命令看到）
- Automatically append version information to the version string（自动在版本字符串后面添加版本信息,编译时需要有perl以及git仓库支持）
- Support for paging of anonymous memory (swap)（使用交换分区或者交换文件来做为虚拟内存）
- System V IPC（System V进程间通信(IPC)支持,许多程序需要这个功能.必选,除非你知道自己在做什么）
- POSIX Message Queues（POSIX消息队列,这是POSIX IPC中的一部分）
- BSD Process Accounting(将进程的统计信息写入文件的用户级系统调用,主要包括进程的创建时间/创建者/内存占用等信息)
-BSD Process Accounting version 3 file format(使用新的第三版文件格式,可以包含每个进程的PID和其父进程的PID,但是不兼容老版本的文件格)
- Export task/process statistics through netlink(EXPERIMENTAL)(通过netlink接口向用户空间导出任务/进程的统计信息,与BSD Process Accounting的不同之处在于这些统计信息在整个任务/进程生存期都是可用的)
- Enable per-task delay accounting(EXPERIMENTAL)(在统计信息中包含进程等候系统资源(cpu,IO同步,内存交换等)所花费的时间)
- Enable extended accounting over taskstats(EXPERIMENTAL)
-Enable per-task storage I/O accounting(EXPERIMENTAL)
- Aditing support - Enable system -call auditing support
- Kernel .config support
- Kernel log buffer size (16=>64KB，17=>128KB)
- Control Group support
- Example debug cgroup subsystem
- Namespace cgroup subsystem
- Cupset support
- GROUP CPU scheduler
- GROUP scheduling for SCHED_OTHER
- GROUP scheduling for SCHED_RR/FIFO
- Basis for grouping tasks (Control groups)
- user_id
- Control groups
- Simple CPU accounting cgroup subsystem
- Resource counters
- Memory Resource Controller for Control Groups
- Create deprecated sysfs files
- Include legacy /proc/<pid>/cpuset file
- Kernel -> user space relay support (formerly relayfs)
- Namespace support
- UTS namespace
- IPC namespace
- User namespace (EXPERIMENTAL)
- PID Namespace (EXPERIMENTAL)
- Initial RAM filesystem and RAM disk (initramfs/initrd) suppor
- Initrams source file(s)
- Optimize for size (Look out for broken compilers!)
- Configure standard kernel feature (for small systems)
- load all symbols for Debugging/ksymoops
- Include all symbols in kallsyms
- Do an extra kallsyms pass
- Disable heap readomization
- Choose SLAB allocator (SLUB (Unqueued Allocator))
- SLAB
- SLUB (Unqueued Allocator)
- profiling support
- Activate markers
- Oprofile system profiling(EXPERIMENTAL)
- Kprobes
