IMX8: How to partition display for two OS in custom image of imx8mqevk with jailhouse hypervisor

Hi, 

Thanks!

Using jailhouse hypervisor to load two custom images in imx8mqevk. Not getting any breakthrough to display the second image of non-root cell. Can you help on the scenario or steps for partitioning the same display screen for both images?

Are you using the imx8mqevk or imx8qmevk board? Which version BSP are you using?

I do not found the official released BSP you are used 5.4.51.  As we do not have the example or document for your need, here I found the code and  i.MX Virtualization User's Guide document do help for you:

Hi,

Thanks!

Does steps available for 5.4.24 bsp to partition display for two OS. Can you suggest more info on the same? I could see jailhouse primary root cell Linux UI is up but not getting how to make non-root cell Linux UI up. Is there any way other than partitioning of display, possible to achieve by using two display screen?
