U-boot中有一个用来保存很多有用信息的全局结构体--gd_t(global data缩写),其中包括了bd变量,可以说gd_t结构体包括了u-boot中所有重要全局变量。最后传递给内核的参数,都是从gd和bd中来的,如上述的setup_memory_tags函数作用就是用bd中的值来初始化RAM相应的tag。 对于ARM平台这个结构体的定义大致如下: inclu...

The macros STRUCT_DECL() and STRUCT_INIT(), on the other hand, are used in modules which declare and initialize a structure handle to a data structure allocated by STRUCT_DECL(), that is, any standard character or block device driver ioctl(9E) routine that needs to copy in data from ...
data_len 中存放的是非线性的数据,也就是整体上不是连续的数据; l(1) 表示的是线性的数据,是连续的。 下图解释了struct sk_buff中head, end, data, tail字段的含义: struct sk_buff结构体中的pkt_type字段的取值为: 通过struct sk_buff中的pkt_type字段中的值,可以判断出接收到的数据包是不是发送给本机...
