 I have a great interest in understanding how low-level things work, how programs run on my computer, how they are located in memory, how the kernel manages processes and memory, how the network stack works at a low level, and many many other things. So, I decided to write yet another series of posts about the Linux kernel for the **x86_64** architecture.
 
-Note that I'm not a professional kernel hacker and I don't write code for the kernel at work. It's just a hobby.

 Actually there are two types of operations may be performed on the data. We may read data and make changes in data. Two fundamental operations - `read` and `write`. Usually (but not always), `read` operation is performed more often than `write` operation. In this case, it would be logical to we may lock data in such way, that some processes may read locked data in one time, on condition that no one will not change the data. The [readers/writer lock](https://en.wikipedia.org/wiki/Readers%E2%80%93writer_lock) allows us to get this lock.
 
-When a process which wants to write something into data, all other `writer` and `reader` processes will be blocked until the process which acquired a lock, will not release it. When a process reads data, other processes which want to read the same data too, will not be locked and will be able to do this.

 This is the end of the second part of the chapter that describes timers and timer management related stuff in the Linux kernel. In the previous part got acquainted with the following two concepts: `jiffies` and `clocksource`. In this part we saw some examples of the `jiffies` usage and knew more details about the `clocksource` concept.

 There are many different `x86_64` specific things already configured after the end of the `setup_arch` execution. For example some early [interrupt](https://en.wikipedia.org/wiki/Interrupt) handlers already able to handle interrupts, memory space reserved for the [initrd](https://en.wikipedia.org/wiki/Initrd), [DMI](https://en.wikipedia.org/wiki/Desktop_Management_Interface) scanned, the Linux kernel log buffer is already set and this means that the [printk](https://en.wikipedia.org/wiki/Printk) function is able to work, [e820](https://en.wikipedia.org/wiki/E820) parsed and the Linux kernel already knows about available memory and and many many other architecture specific things (if you are interesting, you can read more about the `setup_arch` function and Linux kernel initialization process in the second [chapter](https://0xax.gitbook.io/linux-insides/summary/initialization) of this book).

 This is the end of the seventh part of the [chapter](https://0xax.gitbook.io/linux-insides/summary/timers/) that describes timers and timer management related stuff in the Linux kernel. In the previous part we saw [x86_64](https://en.wikipedia.org/wiki/X86-64) specific clock sources. As I wrote in the beginning, this part is the last part of this chapter. We saw important time management related concepts like `clocksource` and `clockevents` frameworks, `jiffies` counter and etc., in this chpater. Of course this does not cover all of the time management in the Linux kernel. Many parts of this mostly related to the scheduling which we will see in other chapter.
