TDA4VH-Q1: if there is a hypervisor layer in the main domain of the TDA4VH-Q1 system software architecture?

tianqiang zheng

Part Number: TDA4VH-Q1

We want to know whether Linux/rtos runs on a hypervisor or directly on bare hardware in the TDA4VH-Q1 system architecture.

Is there a ready-made document that can clearly explain this argument，or could you please provide an architecture document for this argument?

TDA4VH支持高级操作系统(HLOS)，例如Arm Cortex A内核上的Linux/QNX，以及R5F内核上的FreeRTOS/SafeRTOS。 SDK不支持BareMetal。

No, you misunderstood my meaning. What I meant was whether there is still a hypervisor software layer between HLOS(that is, Linux, RTOS) and bare metal.

Why do you need a hypervisor between RTOS and Linux? Linux is running on the Arm Cortex A cores whereas the RTOS is running on the R5Fs. Do you plan to run some flavor of RTOS also on the A72 cores along with Linux? QNX however has an offering with QNX hypervisor, but for example, some kind of Jailhose demo is not there in the SDK today.

Ok, I understand that there is no hypervisor software abstraction layer between HLOS and bareMetal in your software framework. Some companies may insert an additional software abstraction layer between HLOS and bare metal to monitor HLOS. OK, so we're done with this problem.
