extra-y:=file-a.o#make-C/lib/modules/<kernel-version>/buildM=$(pwd) "m" 表示是 loadable kernel module 的 target(区别于 built-in 的内核模块),"y" 表示一个 object file 将被链接进一个 module(用 "<mod_name>-y")或者 vmlinux(用 "obj-y"),三者之间的关系可表示如下: 在整个过程中,作...
更麻烦的是,从一个系列的内核转到另一个系列的内核,比如从2.2.x系列转到2.4.x系列, 可能会由于使用某种(某些)内核工具(kernel utilities)而产生一些问题。 这就是所谓的“modutils”(译者注:可以看为“Modules Utilities”的所写,这样就不会对这个名称感到费解了),包括代码(code)需要载入(load)的内核模块(kernel ...

Lets create a basic loadable kernel module. #include <linux/module.h> #include <linux/kernel.h> int init_module(void) { printk(KERN_INFO "Welcome...\n"); return 0; } void cleanup_module(void) { printk(KERN_INFO "Bye...\n"); } So...
14. Modify the kernel configuration according to your wishes. For example select "M" for "Device drivers -> Input device support -> Joystick interface" to create the module "joydev.ko". 15. Leave "menuconfig" and save. 14. Enter "make CFLAGS_MODULE=-fno-pic modules". ...
Kernel log buffer size 我选15,双核。如果你用ia64,要选16。 Control Group support 集群支持?可以不要 Choose SLAB allocator (SLUB (Unqueued Allocator)) 内存管理模式slab和slub选择slub。 2、在“Block layer”里,假如没有2TB的硬盘,就去掉:Support for Large Block Devices 。Support for Large Single Fil...
