Clarification on virtualization capabilities on STM32MP1x SoC

Greetings everyone

There is a wiki article (closed to the public) about enabling Jailhouse on STM32MP1x that lead me to believe that the STM32MP15x 's Dual Cortex-A7 cores implement the Virtualization Extensions.

To my understanding, the reference manuals do not state anything about its implementation, apart from its support reported in the GIC and Debug sections.

I need some clarity about this matter: Does anybody know if the Virtualization Extensions are implemented on the STM32MP15x's cores but not (yet?) documented in the ST reference manuals?

Link to the referenced article: https://wiki.st.com/stm32mpu/wiki/How_to_enable_Jailhouse

Hello,

I confirm that virtualization extensions are present in all STM32MP1 series Cortex-A7 core(s).

This is clearly stated in datasheet (see section 3.1, of e.g. STM32MP157C datasheet DS12505)

Great!

I am working towards bringing Jailhouse on a STM32MP157A and I really needed this confirmation. To be honest, I was expecting a more explicit statement in the datasheets, regarding the Virtualization Extensions, in a similar fashion to what is reported for analogous products on the market.

Thank you for your answer
