将模块从内核中独立出来,不必预先『绑』在 kernel codes 中。这样做有三种优点: 第一, 将来修改 kernel 时,不必全部重新compile,可节省不少时间;第二, 若需要安装新的 modules ,不必重新 compile kernel,只要插入 (通过insmode指令) 对应的 modules 即可;第三,减少内核对系统资源的占用,内核可以集中精力做最基本...
kernel.kexec_load_disabled 表示kexec_load系统调用是否被禁止,此系统调用用于kdump。当发生了一次kexec_load后,此值会自动设置为1。 0:开启kexec_load系统调用 1:禁止kexec_load系统调用 kernel.keys.gc_delay kernel.keys.maxbytes kernel.keys.maxkeys kernel.keys.persistent_keyring_expiry kernel.keys.root_max...

CONFIG_MODULE_SIG:Module signature verification 如果开启了该选项,在内核在加载内核模块时,会对内核模块的签名进行检查。 默认情况下,在加载没有签名或者是签名不正确的内核模块时,内核仅仅是打印一条提示信息,比如: k_netlink:moduleverification failed: signatureand/orrequiredkeymissing - tainting kernel ...
这确保了“内存中”标志将允许 DPDK 运行,即使整个文件系统是只读的 /var/run/dpdk eal_get_hugefile_prefix eal_set_runtime_dir strlcpy(runtime_dir, run_dir, PATH_MAX) eal_adjust_config eal_auto_detect_cores -> eal:限制核心自动检测,当未指定以下选项时,此补丁使用 pthread_getaffinity_np() 来...
except that some necessary components may be loadable kernel modules rather than part of the main kernel. On some machines, you may need to load these kernel modules before the true root filesystem is mounted. We’ll cover this problem and its initial RAM filesystem workaround solutions in 6....
To allow the the Auto-Protect kernel modules to load, you can either disable enforcement of the SELinux policy or create a custom SELinux policy to allow the Auto-Protect kernel modules. To disable SELinux enforcement: Open the following file in a text editor: /etc/selinux/config Change ...

modprobe可以解决load module时的依赖关系,它是通过/lib/modules/<kernel-version>/modules.dep(.bb)文件来查找依赖关系的;而insmod不能解决依赖问题。 如有2个模块g_file_storage.ko和udc.ko,g_file_storage.ko依赖于udc.ko,在加载g_file_storage.ko前必须先加载udc.ko,如果使用insmod加载,必须按顺序一个一个...
