As the most advanced and generally used operating system in the world, [Linux](https://codersera.com/blog/linux-interview-questions/) is continually improving with each release. From desktops to servers, to cloud-based systems, Linux provides many solutions that can satisfy different needs.
You can't deny that _Linux is a powerhouse for all types of technical work_, but when the topic comes to the gaming industry, it falls kind of flat.  Valve's Steam Deck is changing this with its open-source game engine that will soon be available in **Linux 5.16**.

_Imagine a version of Linux with integrated desktop games. It's now possible with the new release of the **Linux kernel 5.16**, but how does it work?_

Recently, the latest update to the Linux kernel was released. The reason for the update is to fix security vulnerabilities, but there are also some new features added. After reading this article, you will know what you need to look out for in **Linux 5.16**.

## 10 Best Features in Linux 5.16


In his kernel status statement Sunday afternoon, Torvalds called attention to that the consolidation window for the new form did exclude any "uh-huh, something isn't working and presently I really want to part where they split in two." Torvalds composed that _Linux 5.16_ won't be an "immense delivery" however will incorporate critical new highlights. True to form, Linus Torvalds declared that the Linux 5.16 bit will reliably convey the most recent highlights, equipment support, and different enhancements in front of the new 2022 Linux distro discharges, so how about we see what's happening.

1. Programmed multicast burrowing, further developed Zstandard pressure, new review support for the io_uring subsystem, and another gadget mapper for producing review occasions sum up a portion of the enhancements made by the new bit.

2. There are likewise a few enhancements for the **Raspberry Pi 4** and other ARM equipment/processors. 

3. This release also highlights a wide range of ARM updates, file system performance improvements, and Apple M1 media.

4. In this kernel, it is planned to introduce support for new hardware for graphics, processors, networks, and ports.

5. Apple M1 chip support has been greatly improved with each kernel version. The changes are small but useful for users with the latest hardware and those looking to improve gaming performance. However (some) new features are added to the kernel and Glibc with every release.
 
6. Information about the new interface can be found in the core source file Documentation/cgroup-v2.txt and the groups(7) man page. This new element could work on the presentation of games running at the Wine compatibility level (just as local Linux games), however, Wine hasn't executed it yet, so we'll need to watch out for what comes next. 

7. The **Linux 5.16 portion** likewise adds new elements to the DAMON (Data Access MONitor) device for observing explicit memory access designs for client space processes presented in the **Linux 5.15 LTS** part, for example, work designs, checking actual memory. 

8. With the arrival of **Plasma 5.16**, these features will be further enhanced, primarily through the addition of an updated notification system that will add interesting features and changes. The person responsible for these changes has been thinking about them for a year, to be precise, about three years. 

9. In spite of the fact that Display Port 2.0 isn't planned for momentum age AMD cards, progress has been made to add **DP 2.0 help to the AMDGPU driver**. 

10. The PowerPC engineering currently upholds the memory security key element, which was first presented in _Linux 4.9 (Intel x86 design as it were)_.

Torvalds reported that the **Linux 5.16** bit will reliably convey the most recent elements, equipment support, and different enhancements in front of the **new 2022 Linux distro discharges**.


## **How to Manage Your Kernel's Scheduler**


The scheduler is a kernel component that decides which executable thread the processor will execute next. The **Process Scheduler** is the main operating system component responsible for selecting a process to run next.

The task scheduler, sometimes called the process scheduler, is the part of the kernel that decides which task to run next.
It is responsible for making the best use of system resources to ensure that multiple tasks are performed simultaneously. 

All other lower priority tasks will not be scheduled until the CPU is abandoned. Tasks are scheduled to the CPU based on their current deadlines using the global EDF.


**Details of the push scheduling algorithm:**


As discussed above, in order to provide **SWSRPS** when a real-time low priority task precedes a higher priority task, or when a task wakes up in a run queue in which a higher priority task is already running, the scheduler must find a suitable run queue tasks.

**

## Pull Schedule Algorithm Details:
**


> 1. The **pull_rt_task () **algorithm examines all congested run queues in the root domain and checks if they have a real-time activity that can run on the target run queue (i.e. the target CPU is in task-> cpus_allowed_mask) and has a higher priority than the action that the target execution queue is about to schedule. 

> 2. The** pick_next_task ()** work searches for the following string utilizing the pick_next_task work pointer of the planning class, which calls **pick_next_task_fair ()** and **pick_next_task_rt () ** for the CFS and RT schedulers, separately.

The execution line of the schedulers RT, addressed by the construction rt_rq, is fundamentally carried out as an exhibit, every component of which is the start of a connected rundown that controls strings of a particular need.

A string is the littlest unit that the part scheduler can deal with freely.
On a uniprocessor framework, the scheduler switches between various strings in a period division way, which can make the deception of different strings execute simultaneously.

**Group Scheduling :**

For example, if you divide tasks into groups based on the user who runs them, CFS will try to give each of these groups the same amount of CPU time. Fully Revised Scheduler Introduced in kernel 2.6.23 and extended in 2.6.24, CFS tries to ensure that each process gets its fair share of CPU time.

 The Linux Scheduler (CFS) allocates time slots for threads by first specifying a period of time during which each thread will execute once.

Privileges and Resource Limits In **Linux kernels prior to 2.6.12**, only privileged threads (CAP_SYS_NICE) can set a static non-zero priority (that is, set a real-time scheduling policy).

The extent to which a pleasant value affects the relative scheduling of **SCHED_OTHER** processes is the same between UNIX systems and Linux kernel versions. 

While the result of the top and chrt orders affirms that there are no planning design changes for portion strings between forms 3.10 and 5.10, they plainly act distinctively between the two centers.

Indeed, the conduct of 5.10 is our optimal assumption, since these part strings utilize the default booking strategy. After careful inspection of the kernel scheduling changes, it is clear that the kernel expects users to specify all scheduling policies as soon as they start RT tasks.

## **Conclusion**

Linux, just like Windows, iOS, and Mac is an operating system that helps one to use or utilize old and outdated computer systems. It is a free open-source operating system that you can get from the internet. 

You can install Linux on any computer that has a DVD drive and an internet connection. Linux is a stable and fast operating system.

Linux helps one to use or utilize old and outdated computer systems. It was developed in 1991 by Linus Torvalds. The **Linux kernel's architecture** consists of a monolithic kernel with built-in networking support, rather than the microkernel architecture used by Windows.
