Linux/AM5728: Multiple OS without Hypervisor

Part Number: AM5728
Other Parts Discussed in Thread: TIDEP-0095

Tool/software: Linux

Dear Champs,

Is it possible to run multiple OS on ARM cores without hypervisor?

My customer is looking for a example to load RTOS binary to core1 on core0 linux. e.g. Linux will be run on core0 and RTOS will be downloaded to core1 at the initial boot time of linux on core0.

When I introduced TIDEP-0095 Jailhouse Hypervisor reference design, my customer afraid about overheads and stability of jailhouse as their target application is very time critical application.

So, if there is a way to make simpler solution than jailhouse, could please let me know your idea?

Thanks and Best Regards,

SI.

    SI,

    Jailhouse is the only supported way to use Linux and RTOS on two different cores. Jailhouse was designed to be extremely lightweight in order the meet the demanding needs of real time applications.

    This is the best supported option I can recommend.
