Re: NUC8 hardware supported?

Wang, Hongbo
 

Thanks for your interests to ACRN.

We haven’t tried ACRN on laptop but the CPU we have validated is Apollo Lake (SoC) and Kaby Lake (Core). Yes we’re using NUC6CA (APL) and NUC7 (KBL) platform which is easier for debug than laptop.

 

We don’t have chance to try NUC8 yet, but which NUC8 model are you asking about? There’re 3 types of CPUs for NUC8.  https://en.wikipedia.org/wiki/Next_Unit_of_Computing

 

 

Best regards.

Can we evaluate ACRN on any laptop?? or it support only NUC hardware??

Please clarify.

Thanks,

Hi Geoffroy,

I have tried Clear OS and ACRN script on a Lenovo standard laptop which doesn’t have either Apollo/Kaby lake processors.
I ran into issue that hypervisor is not booting at all :).
I will try it on a NUC hardware soon and let you know the result. We have to order the supported NUC box and evaluate on that.

Thank you.

Do you already have one of the NUC listed on the "Supported Hardware"

It's great to hear you'll be evaluating ACRN and Clear Linux, please
let us know how you get on, even if you don't hit any issue ;-)

We do not test it on standard laptop. The likekihood of success
depends
amongst other things of the processor you have on the laptop. We
test
ACRN on Apollo Lake and Kaby Lake processors. You also need the
laptop
to have an EFI bootloader.

I guess you have seen the relevant pages in our documentation by

Install and Test by using simple applications

Hi Team,

I want to test ACRN by installing and using it as hypervisor. Please let me know the guide which I can follow and make use of this hypervisor.

Also I want to test it on a laptop. Please let me know the requirements.

ACRN Project Technical Community Meeting Minutes - 6/26/2019

  1. ACRN project update 
    2.
 
  1. FU, Kaige: Enable VxWorks as RTVM on ACRN
    2.
Download foil from ACRN Presentation->ACRN_TCM->WW26’19
 
Q1: Regarding to polling mode driver, will CPU become always busy?
A1: No. There’s a timer to trigger the polling periodically?
 
Q2: Guest VxWorks is working on ACRN’s Sharing Mode, right? Have you tried VxWorks in partional mode?
A2: Yes, currently VxWorks is working on share mode. In our ACRN 2.0 roadmap, we’ll support Zephyr as Safety VM in partition mode. We haven’t tried VxWroks in partition mode but it should be doable.
 
Q3: Can we boot VxWorks as Guest VM without additional patches to VxWork?
A4: Yes. The vanilla VxWorks can run on ACRN. The additional patches are to enable RT capability for VxWorks when running as Guest OS.
 
Q4: Which chip support ioapic passthrough?
A4: We passthrough local apic, not ioapic. Right now, it can support KBL, WSL platform.

ACRN Project Technical Community Meeting Minutes - 6/19/2019

Wang, Hongbo
 

 
ACRN Project TCM - 19th June 2019
Location
Agenda
  1. ACRN project update
  • In the 2-days IoT Open source seminar, toegher with other Intel open source project, like Zephyr, Celadon, StarlingX, we delivered total 30 technical speeches, 13 demos and 4 hands-on/workshops, gathered 161 community developers, software engineers, technical managers from our key partners and customers, as well as sales/marketing/technical staff from various Intel BUs at the event, in which 50% are from external.
  • This is 2nd Meetup for ACRN project one year later. More than 40 attendees are community developers or partners.
  • For the first time, we had external speakers to deliver 5 of 11 talks. For example, Neusoft’s production-ready Software Defined Cockpit (SDC) system based on ACRN, Hoperun’s add-on features for ACRN, etc.
  • “Seeing is believing”. Neusoft (OSV) brought their “Neusoft C4 platform” SDC demo to seminar. A local OEM car model based on C4 system will be rolled up in Q3’19. This existing news created a lot of buzz in the conference.
  • 5 ACRN demos from community and Intel.
  • All seminar foils have been published in Google folder and Baidu folder:

ACRN Project Technical Community Meeting (2018/11-2019-07): @ Weekly Wednesday 11AM (China-Shanghai), Tuesday 7PM (US-West Coast), Wednesday 3AM (Europe-London)

Wang, Hongbo
 

Topic of WW25.3’19 (6/19 PRC time): Understanding and Mitigating Inter-VM Interference 
Description: ACRN Functional Safety: Understanding and Mitigating Inter-VM Interference. Freedom from interference is an important property in functional safety scope, and it applies to ACRN which aims at consolidating multiple applications into mixed-critical VMs. This talk will provide an overview of interferences in consideration and deeply dive into temporal interference which is still a hot research topic. A concrete understanding based on evaluation will be presented, which also motivates the current proposals what are in the scope of ACRN, how we plan to mitigate and the residual effects after the mitigations have been applied..

Re: Good news! 1st part of ACRN patch has been merged into Linux kernel tip tree!

Congratulations, this is an important milestone indeed!!!

Subject: [acrn-users] Good news! 1st part of ACRN patch has been merged into Linux kernel tip tree!

 

We’re excited to announce that 1st part of ACRN codes, regarding to /arch/x86 changes, have been merged into Linux x86 tip tree by maintainer Borislav Petkov (bp@...) . If no big surprise, those patches will be pulled into Linus kernel tree after v5.3-rc.

This is a big step for ACRN upstreaming, which means ACRN begin to sit side by side with XEN, KVM, JAILHOUSE.

We’ll continue our upstream work for the complete ACRN functionality. Stay tuned!

Subject: [acrn-users] Audio Requirements for SOS & Android Guest using VirtIO

 

Hi,

I’ve been trying to sort out what is and what is not required for an SOS and Android guest configuration using VirtIO.

I am currently setup for 0.5.2 on MRB Rev E.   I was wondering if I could get some clarity from the Audio expert(s) on this topic.

·         Audio VirtIO driver stack:

o   For example: Which audio drivers should be loaded? Not loaded? (SOS and Android):

§  snd_soc_skl

§  snd_soc_tdf8532

§  snd_soc_sst_bxt_sos_tdf8532

§  snd_soc_skl_virtio_be

§  snd_soc_skl_virtio_fe

§  snd_soc_skl_ipc

§  snd_soc_sst_dsp

§  snd_hda_core          

§  snd_hda_ext_core

§  others?

·         Audio Firmware Collateral (SOS and Android):

o   Required firmware files and locations, required links, etc.

·         Misc

o   Required kernel config settings (SOS and Android):

o   launch_uos.sh modifications

§  Any other special system steps required to enable/launch the VirtIO audio service

o   etc.

Thanks in advance

Q1: GVT-s support multiple users in UOS?
A1: Multiple users support in UOS doesn’t rely on GVT-g
 
Q2: Can UOS detect virtual display dynamically?
A2: No. Right now GVT-g doesn’t support hot plug in UOS.
 
Q3: is there any limitation on display resolution?
A3: Yes. To balance the plane numbers and resolution, we had to limit the display resolutions because of limited DDB resource in GPU hardware. Right now we support maximum three monitors with 1080p resolution.
 
Q4: Is there a monitor and a vdisplay device both in the UOS?  
A4: There’s no vdisplay device in UOS. Only a virtual GPU hardware and monitors reported by virtual GPU.
 
Q5: As far as physical monitor is concerned, how do we switch between display from SOS/UOS-1/UOS-2? Do all of them share the same screen or we need to switch?
A5: The AcrnGT framework doesn’t limit dynamic switch usage, but customers need to modify the code to implement such scenario. For example, users can implement a sysfs node to expose the plane ownership variables so that they can be modify in runtime.
If users want to share one screen, right now, they can set the SOS display on plane 1, UOS display on plane 2, etc.
 
Q6: does this degrade compositor performance?
A6: Plane restriction will degrade compositor’s performance, because if limited planes exposed to the driver, sometime driver will not be able to leverage the HW composing.
 
Q7: Do you have a photo of showing displays from SOS and UOS?
A7: No live demo for this TCM talk this week.
