Consolidate Real Time and HMI with ACRN Hypervisor - Jack Ren, Intel

With the increasing momentum of embedded devices getting smarter and always connected, it is prevalent to see that more and more industrial automation manufacturers (Siemens, Beckhoff, Inovance, etc) are combining multiple platforms (PLC, HMI, MC, Robotics, etc) into the the single products. The virtualization is the key technologies to empower such kind of the workload consolidation. However, one of the challenges is its strict Real-Time requirements. Some of the products need the Real-Time task’s scheduling latency to be less than 30us or even less.The traditional virtualization solution is unable to hard to achieve the Real-Time requirements above. For example, the KVM is only able to achieve 100us-level scheduling latency. This talk will present those challenges and how ARCN Real-time is designed to overcome those challenges and meet the industrial-grade Real-Time performance.

A

B

C

B

Like to thank you very much for being so patient, so first of all self introduction, I'm Jen from Intel department before original members, OTC.

A

A

B

Sober questions. How many of you know a crop raise your hand, please a lot.

C

B

For industry sector industry.

B

A

B

A

B

I need to share with you a lot information, otherwise, lots of information would be lost.

A

B

These are relating to those.

A

Three questions.

B

Certified minutes, so I will deliver my presentation within 30 minutes. This is the table. Contents first is apron. What is apron 60% of the audience today know a crumb. Further % do not know so.

C

B

Reduce this briefly, second, is industrial use, kill jr.

A

B

B

America Japan, we talked a lot about on board a vehicle so that words are focused last year and this year we will focus on industrial example cases but of course, will continue to work on automotive and industrial would be our expanded area this year and the persuade is about architecture, perfer roadmap.

A

B

Roadmap technology, a par 5 or have a link, including which head group so I, will provide the accurate code and you can.

A

B

To join us for further.

A

B

Also, I have lots of extra information for you to have deeper dive the details of technologies, depending on how much extra.

C

B

Will have so first of all, what is our crown.

B

B

Upali 1 x, equals function.

B

Pre-Start sorry.

A

B

Technically she.

B

Starts hypervisor for IOT workload, consolidation also in 2018, Linux Foundation. We launched this project until now. It has been carried out for about a year if our open source, our team, developed this for about one year. So from beginning till now, it's about two.

A

Years lifetime.

A

B

Development, we set lots of targets first of all, first servers and technologies. We need to set this apart. Otherwise we did not need to create the Algrim and sever differences. First of all, a small.

A

Footprint relating.

B

To size, the current.

B

Is about 31,000 lines if you have a look, how to keep the end? It's about medium or even tens of millions.

A

B

If this is for commercial enterprises, this scale would be far.

A

More than thirty.

B

A

Second, we.

B

Mainly focus on Io T, so lots of special needs, including what I mentioned before equipment. The second is with an IOT area. This is a heterogeneous work. Both consolidation, including written and no real-time,.

A

B

Safe and non safe.

A

B

Two different types of business to be consolidated.

C

B

License is BSD license very flexible.

A

B

Different to the others, we also have the other key values, including system security. So we have BT tabac the virtualization.

A

B

A

Pack, a crunching.

B

And to schedule this also, we can use kubernetes for scheduling and orchestration no problem. We have our internal cost and not open-source now, so these are the positioning for our value.

A

B

Then they focused on automotive.

B

Scenarios, our council to the integrated OS, the irritant so standardized to two platform. One is council, another is a onboard entertainment. Lots of the customers also use three screens or first grades, and we can also support this.

A

So in May this year we.

B

Launched the 1.0 version, but in this as okra 1.0, this is also a very large milestone on the basis our clients have introduced this into the products for confidentiality. I cannot.

A

B

Our clients for you, but in the future you will notice our our own technologists in the vehicle. No more details to share with you also Android.

A

B

The other OS we can also provide support.

A

B

Focus on this time today, in terms of industrial site, let's.

A

B

At this narrow.

B

Friend uh strong, there are lots of uniqueness.

C

B

Now only one the audience today raised his hand and he's working for industrial site and currently the consolidated parts.

A

B

Is real-time applications, including.

A

B

Applications like this another workload, interaction.

A

B

The production line we have a counsel for.

A

The workers to operate.

A

B

Machines can be controlled, for example, the American controlling the tooling can be controlled by this console in the conventional scenarios. We have two.

A

Independent systems.

C

A

B

Manually to put.

A

This onto the same to t.

A

B

If you participate in the industrial trade shows you'll find that this is a small Council and have a to put it in the front and also its both have in the windows.

A

B

Flashy not very appealing, just very simple programs: you can notice is XYZ coordinates and the program operation situation on the back end. They would put the two T. So this is very typical scenario: lots of manufacturers work for the council's. The nature purchase the products from Japan from a Mitsubishi or from the other oversea companies. The cost is very high, very expensive.

B

Looking to the Future come across. Only these two parts together, which is real 10 applications.

B

Industry sale you winning this as the consolidation among the two. Currently, we don't have multiple solutions to choose. I know cement has their solution and another manufacturer. So in this area they have very fierce competition. Who can win this market? Their products can be improved a lot today. We will mainly focus on the consolidation and.

A

B

A

B

A

B

With the other chip how to consolidate this narrows? Normally we do like this. The typical scenario is like this, as I mentioned before the council and the windows.

A

B

In the operation, condition covers about 60.

A

To 70 percent or even.

B

Higher market share, we use these works for.

A

C

B

China, we also have lots of domestic flights. They use Linux based.

A

A

B

Reduce R&D constant because VIX.

C

B

Price is very high.

C

A

B

A

B

Another also works very well very important safety.

A

B

You see in the industrial is very important certification.

A

B

Very difficult to be certified by IEC. You have to guarantee the safety level, at least in the.

C

A

B

Avoid fires down times or.

A

B

Loss of expensive components, so safety very important in terms of automotive sector ISO 26262, is a very important certification, so we will focus on this few.

A

A

B

The things to consider normally, we do.

A

Not like this first of all,.

B

Resources would be segmented would be categorized into two.

A

A

B

We also have the fire as.

A

B

C

Today, before value, we use H.

B

450 guaranteed it can be used to monitor the hardware and condition to generally healthy collision. If anything happens, it can send alert.

A

Hero time, so safety alert on the right.

B

Partition so this has.

A

A

B

At least supports one.

B

Emulate multiple PLC's or census, whatever mission wide.

A

B

A

B

On CPU capability or the resources for.

A

B

Will reduce the resources consumed.

B

Through service thank.

A

B

Also prevent sharing services and the back kind of us. Apart of this.

A

B

Are the difficulties all come across? First of all makes the criticality, so it's integrated real-time narottam and give us lots of contacts.

C

The complexities.

B

C

B

This needs to prevent for the interruptions if you are executing the events and accessing cache, the window is also based in cache.

A

Accessing cache, l3 cache then.

B

The cow sure would be interest.

A

B

C

Would be influence and for next access or execution. This.

B

Data or commands needs to have some changes and the real-time will be influenced.

A

So this is the interference the.

B

Biggest challenge for us to deal with senior. The second is safety.

A

B

We regard this as lifted on.

A

A

B

We have passed through certification for safety domain.

A

B

Corporate response about the certification agencies, but for.

C

The right parts.

B

They were perceive very difficult to pass certification.

A

B

Have accumulated the experiences.

A

B

A line of code.

A

B

Certification cost is verify a hundred two hundred five fifty US dollars so.

A

D

Is not possible to certify that you enter the system will be divided into two parts: the safe.

A

And unsafe parts are.

D

Here it's my the interfered. The unsafe part may only go back to the safe part. How to attract a solution is also important at that isolation and sharing. Of course, we want to share the resources. Otherwise, why do we.

A

Go to work load, consolidation on.

D

The other hand we want to have isolation, because we don't really either os2.

D

Otherwise, the component.

D

A

A

D

Your own spy reach and your own network, and this.

A

Is the best way between.

D

Our systems sure to be implemented really.

A

Through? In the same level and.

D

Of course, maybe some interference generated and so.

C

D

A

A

D

The run time is I wanna tricks.

A

D

A

D

Also, the interactive.

A

D

D

Which is always about to measure in.

A

D

Usually for the task scheduling the desert, you're going to be around one millisecond or ten.

A

Milliseconds and.

D

Then the a chime.

A

D

A

D

A

A smoke detector from the lefty closest to us, which is pretty much all.

A

D

A

Pretty much a suit, or is it.

D

Is called the pre-launch, the safety OS and on the right it has a post launch to resume and.

A

The service vm in the middle.

A

D

To start before that, and on the right, it means.

C

D

After and for the first launch, the vm, it is referring to the saddest p.m. not the ikran device model to start it. So this is.

A

The basic concepts in the Union and.

D

For the phone photos, how would we use them one on the left of the cs50 OS? It could be shoot to be restraint to fire me.

A

Watch machine if.

D

A

D

The socially OS on the left could still continue working.

D

The operators could.

A

You took them into innovation, Wiseman and.

D

A

D

Tv and a real time.

A

D

Run the real tiny, my OS, it is to run the control codes.

A

A

D

Then to operate the production devices.

A

D

Then about the devices we support, you can see many of them nest.

A

D

A

D

I was like to point out will be used to in.

A

A

D

Durden, the profanity would be used more often like for Siemens.

D

Lease would be based on the private protocols and forty.

A

D

Standardized protocol I, like the private.

C

Ones, it is public and a unified.

D

C

In the English train and it's.

A

D

Is that it could help achieve connectivity between the products.

A

And for TSM it.

D

A

D

To control the device like the TLC would throw TSN to send the network package and.

A

Learn to drive the motor, so your.

D

Network, real-time and the TSM is.

A

D

Time-Sensitive network.

A

D

With virtualization, you could achieve the real, timely fashion.

A

D

Then about FPGA, it might be needed for some mathematical process and.

A

D

For FPGA, we were there having to cut through through our TPM and.

A

D

Directly, access FPGA.

A

D

We also have some customers asking whether they could be shed.

A

D

That we would support multiple simulated PS PLC to visit the same FPGA. But now we do not have clear answer to.

A

D

You want to virtualize FPGA, it's not that difficult to factor. You want to make it real time. It is quite tricky, so we may need a further design.

A

And the next one.

D

A

A

D

Board from ten men system, they need to share the same GPU, but either industry hm is.

A

Not the case so.

D

Gpu is mainly for Windows.

D

Not for mediated pass.

A

Through further.

D

A

D

Back-End is in our room. Service did I serve this.

A

D

A

D

Hr I and windows. The main reason to use this is to avoid interference.

A

D

We just do to directly use it for Windows. Windows is not that reliable, reliable. Some people may think. Windows is a malicious, a Malaysia's system.

A

D

Would lead to some problem.

A

D

Problems happen, it may cause cracks of the whole system and the graphics travel under Windows. Then the graphics may be collapse by the probabilities quite low, but was it happen in to will lead to the failure in the whole system.

A

D

We'll want to address this issue.

A

This way and other devices to adjourn.

D

A

Let's now look at safety.

D

Training you to meet the IEC 61508 standards and.

A

Here we divide the system into two parts: I left.

D

The low part is a higher on the hypervisor.

A

D

What was it about, and.

A

D

C

D

Is a city certified by Intel or customer, but Intel will not finish everything. Some details will be left to the customer because in general is not offering and to end.

C

Solutions, customers.

A

D

To cover part of the job and.

A

D

Need to certify it by.

A

D

As well, this is the Left Front which we'll call my sector related part and.

A

D

A

D

Non safety parts do them, they may run the Linux system.

A

D

A

This is not about.

D

There, the safety, certification.

A

D

We want to make sure the right part will not interfere. The left one.

A

A

D

To avoid the right part.

A

D

Am Coatesville to prevent the non safety codes to affect.

C

D

Safety once and I will not dwell on the details, because the other day we had.

A

Meet happy event when.

D

More than 100 developers attended and we also published our tutorials at that event,.

A

D

That you could know more details.

D

Window as HMI domain in the industry window safe dominating, and maybe people will ask how about Linux Linux is easy. They need to operate. The main thing is in the industry for the eye tears. If we want to attract a problem, that's easy, but in industry it's not the case. Maybe they are not. They are not ideas, they are like mechanics and they don't know about programming.

A

D

Maybe those codes are just used to run a Windows rather not even earlier editions and the compatibility made me not that ideal, but reliability here is quite a critical, so we want to make sure that to where the upgraded system, the codes could still run the.

A

Compatibility is quite important here and.

D

We want to make it here.

A

D

If we want to make juice images, we need to first of all force parties. We need to adopt only ms.

A

D

Want to avoid change to windows, because it's kind of sauce.

A

D

A

A

D

Lot of them could to be not only demonstrating.

A

D

Addition, we also support.

A

D

Putas, a secure boot.

A

D

A

D

Will adopt a watch TPM the virtue virtue TPM to do it.

A

D

For the secure boot, it is like this.

A

D

For Microsoft for virtualization they've initiate their own framework, which is called hyper-v.

A

D

Will not support the reset of hyper-v just a subset, which is called TL FS, the hyper-v hypervisor top-level functional specifications. We would support this one.

D

Another example would be, as I mentioned, window sister Malaysia's.

A

D

Our Intel hardware platform, we also have GT class.

A

D

Class for the grad fitness it could access to part of the cache and.

A

D

May interfere with.

A

D

A

D

Realize real time without the key technologies, the first will would pass through the local keygen.

A

To the RT BM interuption.

D

Of the processing just to to interfere with the OS and the hypervisor will not be intervened to reduce the latency and.

A

D

Key technologies today, Bobcat.

D

Future hearing is.

A

D

A

D

The RTM it will have our exclusively occupied cache and not interfere with other OS and in our file.

D

Turn off some future that will includes the real-time performance.

D

But when you do not have the customized the BIOS and we need to follow a guideline to customize it and we need to offer these options so that before shipment, the option.

A

Which was also closed.

D

To avoid further unnecessary inference, but how about its we're.

C

Tired performance, we're.

D

Happy evaluating the real-time light.

A

A

D

Have the intel core cpu with 1.98.

D

Bigger memory we.

A

D

Have looked, pre marty proposed and we would benchmark both on their configuration and places.

C

D

On the new average, you compare the lower.

C

D

C

D

It is distributed to enter the more closer the closer to the left.

A

D

Which is how far.

A

D

On the right, it is the overall chatter.

A

D

And over to house you can see it is closer to that upper part and the.

A

One you can see.

D

Ats, a pouch, the eight crumbs.

A

A

D

Our 2019 results. We have something to tell policies to maintain them, and this is also derived from the eight raamaiah.

A

D

We also have our data.

A

Paper published for your reference uses: this is our roadmap. You can.

D

See the controls, green and red parts are about our real time, real time and by the end of the year we want to activate all the futures. These are our major goals and we're approaching the end here, you can scan the QR code to join our we check. Actually, this is my personal which had counters, because our group is big enough. You cannot join and you can just the scan the QR code at me on each end.

C

D

I I can introduce you to the group. Any question.

D

Interpreter come to hear anything.

D

It's all expenses combined for development, for construction, I didn't quite get you on the safety.

A

D

A

D

Different levels.

C

D

A

A

D

Need the more redundancy on the hardware.

A

D

It is not isolation physically in John. What is your fundamental method for the certification.

A

D

Go back to this slide.

D

A

D

Standards, it stipulates what conditions you need to meet, but here.

C

Our certification.

D

We will try our best to.

A

D

You safety a license to.

A

Some mr. Kurien hard.

D

To wear coat I do we also have stom hardware.

A

D

Have regular three buses examinations: every 125, a millisecond.

A

D

If problems happen, it will be warning, but how would you guarantee you the time sequence and storage of the directives.

A

D

Influence, that's what.

C

This is a very.

D

Good question is.

A

D

We're making effects on for the ones most each and every director and are also very efficient.

A

C

D

Be generous to all codes should be thoroughly analyzed to make sure there's no problem.

A

D

Three lines of code: it needs a safety requirements, I think there are so many scenarios.

D

A

D

Put on this 100 US dollar, it is.

C

Between 150 and 200.

C

D

You can have two pathways and then Union decide I'll decide which one to choose. This is our one axis that perfection to realize.

A

D

If we put the codes into.

D

A

D

Should be tested to make sure it meets our expected condition so bottom layer, you as a BIOS, you made a lot of settings right. Thank you.
