My technology affects the whole world

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

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

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

In particular, Yu Dazui's bragging and marketing made many Chinese people feel a little disgusted with Xia Wei's behavior and identified Xia Wei as a pirate, which was quite controversial.

In a conference room of Tianyu Xinghai, the system R\u0026D personnel moved in by Xia Weixin also met with the R\u0026D personnel of Tianyu Xinghai and exchanged technologies.

The person explaining the Hongmeng system in front of Ma Tian now is their senior mobile phone system engineer Ran Shaobin.

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

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

We will still use the same five-layer architecture as Android. Considering that in order to be seamlessly compatible with Android, we have to retain the Android runtime... Ran Shaobin talked in front of the screen, detailing the direction and progress of Xia Wei's current research on the Hongmeng system. Said it for a while.

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

When encountering confusion, he would also raise his hand to ask questions, interrupt Ran Shaobin's speech, and let Ran Shaobin answer his questions.

Ran Shaobin also felt a lot of pressure from above, especially when he saw Ma Tian sitting below, listening to his explanation with a serious look on his face.

It felt like he was doing his graduation defense as an undergraduate. At that time, there were two academicians and a professor who had returned from Stanford.

Even vaguely, it was more terrifying than the feeling of defending in front of a big boss.

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

That's probably all. At present, we are still writing the lib library based on our own Kirin chip! Ran Shaobin talked for about half an hour, looking at Ma Tian waiting for the final question.

Have you finished speaking? Ma Tian said.

Ran Shaobin nodded.

Throw away the Android and Linux kernels! Ma Tian said.

The main reason why Xia Wei retains the Android architecture and Linux kernel now is that the time is not mature enough.

One is that they are afraid that their technology is not mature enough and that the operating system they develop is unsafe!

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

There is a type of vulnerability in information security called zero-day vulnerabilities, which refer to security vulnerabilities that are 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 conduct process attacks. This kind of attack is incredible in the field of core infrastructure.

To give a vivid example, an attacker can force the memory and CPU of the mobile phone in your pocket to run crazily, and then cause the temperature of your chip to become too high and start to spontaneously ignite.

It is equivalent to controlling the current of your equipment 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 takes time and a large number of examples to verify.

The Linux kernel has gone through thirty years of ups and downs from 1991 to the present, and its security and reliability have been verified by time.

The second is to consider the cost. Yingjiang has not yet started on the open source agreement, that is, it can still use Android and Linux.

Abandoning Android and Linux and rewriting the kernel would be too costly in terms of time and price.

Being compatible with Android and continuing to use Android and Linux kernels are the options with the lowest cost and the highest benefits.

Of course, Xia Wei is also a little afraid of completely abandoning Android and Linux and making Yingjiang unhappy. After all, this involves issues of interests and status.

This won't expose the scars.

Just abandon Android and the Linux kernel? Ran Shaobin and a group of Xia Wei engineers opposite were a little surprised. A group of people looked directly at Ma Tian.

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

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

Naturally, no one present was stupid enough to question Ma Tian. Even the engineer from Tianyu Xinghai took the lead and said, Have confidence!

Just kidding, with Mr. Ma leading the way, how could he not be confident!

Xia Wei can only follow the crowd. Although many people have a little doubt in their hearts, this is human nature and cannot be avoided.

In their view, completely abandoning the Linux kernel will involve even more things. First of all, many driver underlying codes need to be rewritten, and the interrupt mechanism GIC must be restructured.

This is a task that is destined to be a huge workload, and you will face various difficulties when writing it.

However, when Ma Tiantou gave them a small kernel written by himself, they all shut up.

Mr. Ma, what is this? Ran Shaobin looked at the compressed package named Tianyuan Kernel and couldn't believe 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 more conveniently cooperate with Ma Tian, ​​and the logic of its operation naturally requires the use of the system.

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

After all, if Tianji's core could be broken by others, Yu Xinghai would really be doomed that day. First, Ma Tian would be murdered by Tianji's control equipment.

This is also the reason why Ma Tian had the confidence to abandon the Linux kernel at the meeting, because he had 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, is there a smart home concept?

Yes, Mr. Ma! Ran Shaobin nodded.

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

For example, open the door, turn on the lights, turn on the air conditioner, etc. on your mobile phone.

It's probably about relying on this aspect, building an ecosystem through this system, which can interact well with other devices and realize the interconnection of everything. This is what a truly excellent mobile phone system should do! Ma Tian said slowly.

In fact, when he wrote the Dimensity core, he relied on this aspect. At that time, he always wanted to turn Dimensity into an artificial intelligence butler like Jarvis in Iron Man.

Later, due to energy constraints, there was no expansion. I just wrote a small kernel system to let Tianji control some equipment in the laboratory.

For example, you can operate a robotic arm to hold a hand and project problems on the screen.

Therefore, the part taken away from the core of the Dimensity system is definitely a good reference for the Hongmeng system that realizes the interconnection of everything.
