[Cyclone 5 (Ref 5csema6u23i7) - HPS] Does PL390 Generic Interrupt Controller support TrustZone security extension?

Hello,

 

After reading the Cyclone 5 Hard Processor System Technical Reference Manual, I managed to find that the Interrupt controller supported is the PL390 Generic Interrupt Controller (GICv1 architecture). However, I was not able to find if the PL390 GIC supports the TrustZone security extensions for enabling secure interrupts.

 

Can someone confirm that the PL390 GIC implemented in the Cyclone 5 platform support the security extensions or not?

 

Thanks in advance for your help.

 

Best Regards,

Kevin

Hi Kevin,

I find some documents describes how ALTERA SoC supports the trust-Zone security, I hope this can help you.

Hi,

 

Thank you for your help. Unfortunately, this document only explains the configuration of a secure memory region with TrustZone, while I'm looking for more information about the support of secure interrupts in the PL390 Generic Interrupt Controller implemented on the Cyclone V SoC.

Actually I cannot find a document that totally confirm that the PL390 Generic Interrupt Controller supports TrustZone security extension. I think it should be supporting but I cannot confirm this.
