PCIe security mechanisms offered by NVidia SoCs for Automotive

Hi,

We are using PCIe communication Interface between the 2 Nvidia SoCs. There is a request from the customer to check on the security mechanisms offered by PCIe peripheral.

By researching online, we have learnt that there are some mechanisms such as IDE, CMA offered by PCIe standards and we were wondering if Nvidia Jetson Orin or any other Automotive SoCs supports any of those features. Even if currently not supported by any of the SoCs, it would be still helpful to know if anything is planned for future. Roadmap would be helpful.

Thanks in advance.
