🌟 Linux Kernel Programming - Timing Subsystem 🌟

Course Headline: Mastering Time in the Linux Kernel: The Timing Subsystem 🚀

Dive into the world of timing within the Linux kernel, where every millisecond counts! This course will guide you through the complexities and nuances of managing time-related activities in the Linux ecosystem.

Course Description:

Timing Measurements in Linux Kernel: Time is of the essence, and in the realm of Linux, timing measurements are crucial for a myriad of operations. From the display's power-saving features to critical system scheduling, understanding how the kernel handles time is essential for any aspiring or experienced system programmer.

🔍 Understanding Timekeeping Mechanisms: The Linux kernel deals with two primary types of timing activities:

1. Keeping the Current Time and Date:

   • time(), gettimeofday(), and clock_gettime() are used to track the system's current time of day.
   • Time stamps for files and network packets ensure data integrity and synchronization.

2. Maintaining Timers:

   • Alarm mechanisms notify the kernel and user space when a certain interval has elapsed, crucial for scheduling tasks and managing system resources.

Hardware Devices and Their Role in Timekeeping: Linux relies on various hardware devices to keep accurate time records:

1. Clocks/Counters: High-precision measurement tools that track the current time of day.
2. Timers: Hardware timers that issue interrupts at a predefined frequency, essential for software timing implementations.

Practical Knowledge and Skills You'll Acquire: This course covers a wide array of topics to make you proficient in Linux timing subsystem:

• Timing Commands: Learn about date, uptime, and other essential commands for system time management.
• POSIX Clocks: Get familiar with clocks like CLOCK_BOOTTIME, CLOCK_MONOTONIC_RAW, CLOCK_REALTIME, CLOCK_PROCESS_CPUTIME_ID, and CLOCK_THREAD_CPUTIME_ID.
