Chapter 223 The Pattern Needs to Be Opened

The research direction of Hongmeng system mainly starts from the architecture.

At present, the technical direction of Xia Wei's research is to be compatible with Android to realize their own system, which is still based on the Linux kernel, and then write some additional link libraries at the HAL layer according to their own chip architecture.

Because it is very similar to Android, many people think that Hongmeng system is a shell of Android system and a pirated version!

Especially Yu Dazui's bragging and marketing, which makes many Chinese people a little disgusted with Xia Wei's behavior, and they believe that Xia Wei is a pirated version, which is quite controversial.

In a conference room of Tianyu Xinghai, Xia Wei's newly moved system developers also met with Tianyu Xinghai's developers and exchanged some technology.

Now, the person who explained Hongmeng system in front of Ma Tian is their senior mobile phone system engineer Ran Shaobin.

Ran Shaobin came to Tianyu Xinghai to see Ma Tian four years ago. At that time, he came with Nie Zhenyuan for face recognition technology. (Chapter 97)

It's just that he remembers Ma Tian, ​​and Ma Tian doesn't remember him very much.

"We will still use the five-layer architecture like Android. Considering that we need to retain the Android runtime for seamless compatibility with Android..." Ran Shaobin spoke slowly in front of the screen, and explained in detail the direction and progress of Xia Wei's research on the Hongmeng system.

The engineers below also listened carefully, especially the engineers from Tianyu Xinghai, who were not familiar with it and even took notes with notebooks.

When they encountered confusion, they would raise their hands to ask questions, interrupting Ran Shaobin's speech and asking Ran Shaobin to solve the confusion.

Ran Shaobin also felt a lot of pressure up there, especially when he saw Ma Tian sitting down there, listening to his explanation seriously.

He felt like he was defending his undergraduate thesis, when there were two academicians and a professor from Stanford sitting down there.

It was even more terrifying than defending in front of a big shot.

Because he had seen how good Ma Tian's technology was four years ago, his brain was comparable to a machine, and his omniscience was comparable to a textbook.

"That's about it. We are still writing lib libraries based on our own Kirin chips!" Ran Shaobin spoke for about half an hour, looking at Ma Tian and waiting for the last question.

"Have you finished?" Ma Tian said.

Ran Shaobin nodded.

"Throw away Android and Linux kernels!" Ma Tian made the decision.

The reason why Xia Wei keeps Android architecture and Linux kernel now is mainly because the timing is not mature enough.

One is that he is afraid that his technology is not mature enough and the operating system he develops is not safe!

The operating system is different from other application software. It determines the life and death of many devices. The security of the operating system even affects the stability of a social system.

In information security, there is a type of vulnerability called zero-day vulnerability, which refers to a security vulnerability that is maliciously exploited by hackers immediately after being discovered. If an operating system hides a large number of zero-day vulnerabilities, it is very dangerous.

Hackers can even directly enter the kernel state from the user state to attack the process. This kind of attack is incredible in the field of core infrastructure.

To give a more vivid example, an attacker can force the memory CPU of the mobile phone in your pocket to run wildly, and then make your chip temperature too high and start to self-ignite.

It is equivalent to controlling the current of your device to cause problems.

Therefore, the security of the operating system is very important. No one knows whether a newly released system has many security vulnerabilities. This requires time and a large number of examples to test.

The Linux kernel has been around since 1991, and it has gone through 30 years of ups and downs. Its security and reliability have been verified by time.

The second is to consider the cost. The Eagle Sauce has not yet started on the open source agreement, which means that Android and Linux can still be used now.

Abandoning Android and Linux and rewriting the kernel will cost too much time and price.

Compatibility with Android and continuing to use Android and Linux kernels is the lowest cost and highest benefit option.

Of course, Xia Wei is also a little afraid that completely abandoning Android and Linux will make the Eagle Sauce unhappy. After all, this involves issues of interests and status.

Let's not open the scars for this.

"Directly abandon Android and Linux kernels?" Ran Shaobin and a group of Xia Wei engineers opposite were a little surprised, and a group of people looked straight at Ma Tian.

Ma Tian explained: "It's a very simple reason. We can make a stable and secure Hongmeng system. There is no need to provoke Android and Linux. I have this confidence. I don't know if you have it!"

After saying this, Ma Tian also smiled on his face, wanting to see if anyone would question him.

The people present were naturally not stupid enough to question Ma Tian, ​​and even the engineers from Tianyu Xinghai took the lead and said, "We have confidence!"

Just kidding, with Ma leading the way, how could we not have confidence!

Xia Wei could only follow the crowd. Although many people had some doubts in their hearts, this was human nature and could not be avoided.

In their opinion, if they completely abandoned the Linux kernel, there would be more things involved. First of all, many underlying driver codes had to be rewritten, and the interrupt mechanism gic had to be reconstructed.

This was a task that was destined to be a huge workload, and it would also face various difficulties after it was written.

However, when Ma Tian threw them a small kernel he wrote, they all shut up.

"Mr. Ma, what is this?" Ran Shaobin looked at the compressed package named "Tianyuan Kernel" and was a little bit unconvinced of his guess.

"This is the kernel code I wrote for Tianji to control some equipment in my laboratory. You can refer to it!" Ma Tian replied.

As an artificial intelligence assistant, Tianji can naturally control some mechanical equipment in the laboratory in order to cooperate with Ma Tian more conveniently, and its operation logic naturally needs to use the system.

This Tianyuan kernel is part of the Tianji system kernel. It was written by Ma Tian himself and has been absolutely verified for security.

After all, if Tianji's kernel can be broken by others, Tianyu Xinghai will really be finished. First of all, Ma Tian will be murdered by Tianji's control equipment.

This is also the reason why Ma Tian has the confidence to say at the meeting that he will abandon the liunx kernel, because he has studied it and wrote part of it himself before.

Ma Tian continued to add: "Don't stick to the mobile phone system, open up the pattern, do you have the concept of smart home?"

"Yes, Mr. Ma!" Ran Shaobin nodded.

The so-called smart home is to control the entire family's home through one device. Xia Wei certainly had expected that their ideal state would be to control all the devices in the home through a mobile phone.

For example, opening the door, turning on the light, turning on the air conditioner, etc. on the mobile phone.

"It's probably in this direction. Through this system, an ecosystem can be established, which can interact well with other devices and realize the interconnection of all things. This is what a truly excellent mobile phone system should do!" Ma Tian said slowly.

In fact, when he wrote the Tianji kernel, he was leaning in this direction. At that time, he always wanted to turn Tianji into an artificial intelligence housekeeper like Jarvis in "Iron Man".

Later, due to energy constraints, it was not expanded. Just wrote a small kernel system to let Tianji control some equipment in the laboratory.

For example, operating the robotic arm to help, let the screen projection problem, etc.

Therefore, the part taken away from the Tianji system kernel is definitely of great reference significance to the Hongmeng system that realizes the interconnection of all things.
