Inquiry: ARM’s Architectural Recommendations for Isolated Hosting of SafeVM, IVI & Trusted SW Using CCA

Vikas Pandey

Hi Team,

I’m exploring ARM’s architectural guidance for deploying SafeVM, IVI, and Trusted Software stacks.

Specifically, I’m interested in understanding how these components can be isolated across different execution worlds to fully leverage Confidential Compute Architecture (CCA) features—ensuring robust safety, security, and confidentiality in each domain.

Regards,

Vikas Pandey

    I’ve noticed there’s been no feedback so far (~1 Month) —so let me put this out there:
    Does Arm genuinely envision Realm being adopted for automotive workloads?

    From my perspective, Realm seems risky for hosting safety-critical tasks like ADAS.
    What’s your take? Is there an official Arm recommendation or roadmap that supports Realm usage in automotive systems?

    Would love to hear your insights—especially from those following Arm’s security and automotive strategy.
