Download Linux Kernel Internals by Michael Beck, Harald Bohme, Mirko Dziadzka, Ulrich Kunitz, PDF

By Michael Beck, Harald Bohme, Mirko Dziadzka, Ulrich Kunitz, Robert Magnus, Dirk Verworner

I discovered the reasons during this ebook to be very transparent, giving adequate element for a great head begin into Linux internals. The publication in brief explains the OS suggestions, akin to semaphores, digital reminiscence, etc., via an summary of the way each one is applied in Linux, and code snippets.

Most of the code snippets are simplified for clarity, which i discovered beneficial as the hacks may be distracting (scary, too) for a newbie. specific and up to date info can top be acquired from resource code itself.

The ebook assumes a few familiarity with Unix innovations, because it mentions such buzzwords as POSIX, BSD, and SVR4 within the context of the discussions, yet you can actually thoroughly forget about them, and simply pay attention to the Linux part.

The publication in short covers including new approach calls, compilinag and debugging the kernel, or even exhibits tips to write an easy equipment driving force - those are not easy to discover in a single place.

Overall, i discovered this e-book to be very important for my self-paced examine (the top so far), and that i in basic terms want they'd a more recent version.

Example text

One of these is the system call alarm, which ensures that the SIGALARM signal is sent to the process after a specified time. Newer UNIX systems also support interval timers (see system calls setitimer and getitmer on page 324). unsigned long timeout; unsigned long it_real_value, it_prof_value, 1t_virt_value; unsigned long it_real_incr, it_prof_incr, it_virt_tncr; struct timer_list real_timer; Linux kernel internails - 37 - The components it_real_value, it_prof_value and it_virt_value contain the time in ticks until the timer will be triggered.

Every time the file descriptor is copied (by the system calls dup, dup2 or fork) the reference counter is incremented by 1, and every time a file is closed (using the Linux kernel internails - 42 - system calls close, _exit or exec) it is decreased by 1. The file structure is only released once there is no longer any process referring to it. All file structures present in the system form part of a doubly linked list through their components f_next and f_prev. The global variable struct file * f1rst_file; constitutes the start of this list.

When these have expired, the task is informed by a corresponding signal. 5 The scheduler The scheduler is responsible for allocating the 'processor' resource (that is, computing time) to the individual processes. The criteria by which this is done vary from operating system to operating system. UNIX systems prefer traditional interactive processes to enable short response times to be achieved and so make the system appear subjectively faster to the user. 4, LINUX supports various scheduling classes which can be selected via the sched_setscheduler() system call.
