Re: Multi-display setup supported by Salvator-XS board

Hello Michele,

Thank you for the quick and very useful reply.

“However XEN is available on the Salvator-X (not sure about the Salvator-XS) and you could use it to run multiple instances of AGL as a DomU.”

Ah that’s interesting, I’ll look into it.

“ KVM is today supported by AGL for R-Car M3. You can build it adding "agl-egvirt" to the list of parameters you use to execute aglsetup.sh.

It is of course possible to extend the support on the H3 as well. If you are interested in doing this I would be glad to support you.”

I would love to get involved in adding the support for the H3, but it would obviously depend on what the effort involved in doing this would be, and whether I possess the skills to do the task. If you could give me a brief idea about the porting effort, it could help me decide.
Having said that, the major difference between M3 and H3 are the core configurations, so I’m hoping its something fairly trivial. 😊

“ps: we'll have the Virtualization Expert Group call today at 4PM CET. You're welcome to join if you like! ”

Thanks for the head’s up. I will try and join this afternoon’s call, but I can’t promise I’ll be there.

Thanks again,

Kind regards,

Umair

Dear Umair,

answering the hypervisor related questions:

Hey guys,

I’m using the agl-demo-platform-crosssdk image built with EEL_5.1.0 on a salvator-xs board and would like to be able to use the 2xHDMI outputs to ideally launch the als-meter-demo on one screen and have the standard Homescreen on the other.

Now, obviously I’m not sure if this is even possible, but it made me curious about how dual screen setups are supported on AGL. I have seen many demo’s at events that use multiple displays yet I have found no documentation or information about implementing this, in the public domain. Am I missing a trick?

I am also keen on running multiple instances of AGL on the Salvator board is this supported by AGL?

Yes this is doable, see my answers below.

Are there any OpenSource Type 1 Hypervisors that can be used for this with the R-CarH3 platforms?

You cannot build a type 1 hypervisor together with AGL yet.

However XEN is available on the Salvator-X (not sure about the Salvator-XS) and you could use it to run multiple instances of AGL as a DomU.

Are there any OpenSource Type 2 Hypervisors that can be run on AGL to run other instances of AGL on it?

KVM is today supported by AGL for R-Car M3. You can build it adding "agl-egvirt" to the list of parameters you use to execute aglsetup.sh.

It is of course possible to extend the support on the H3 as well. If you are interested in doing this I would be glad to support you.

I appreciate the fact that there are a lot of theoretical possibilities, but would like to know if there is a tried and tested way of doing the above with AGL.

Additionally, I am now unable to get the Homescreen displayed on the Salvator board. It launched (even though delayed by 20-30 secs) the first time I boot the image. But have been able to get the homescreen after subsequent re-boots. Any suggestions?

Kind regards,

Umair
