Linux. The Linux kernel, in the form of Linux-Libre, became part of the GNU project. Thus, GNU running the Linux kernel, or GNU/Linux. The GNU Toolchain A GNU distribution typically runs a Linux kernel, although GNU Hurd remains available for non-mission-critical testing. However, what se...
Most people, even people who dabble withLinux, don't quite grasp the distinction between Linux, GNU/Linux, and the GNU toolchain, but the differences matter when you're thinking about certain kinds ofsoftwaredependencies. Linux and GNU Linux follows from a chain of development that started with...
What is the difference between user level threads and kernel level threads? A kernel thread, sometimes called a LWP (Lightweight Process) is created and scheduled by the kernel. Kernel threads are often more expensive to create than user threads and the system calls to directly create kernel th...

1. kmalloc()分配的内存处于3GB~high_memory之间的一段连续内存,这段内核空间与物理内存的映射一一对应2. Linux处理内存分配通过创建一套固定大小的内存对象池。分配请求被这样来处理,进入一个持有足够大的对象的池子并且将整个内存块递交给请求者。驱动开发者应当记住的一件事情是,内核只能分配某些预定义的,固定大小...
