Enabling pointer authentication on ARM FVP Base

Mohannad Ismail

Hello,

I want to use the ARM pointer authentication feature. I compiled a program with PAC instructions. I inspected the assembly and made sure they were properly inserted. I also compiled and ran an ARM Base FVP and was able to share the directories in order to run the program. However, the FVP gives me an illegal instruction. I am sure the kernel supports it, since it is version 5.3.0. How do I enable PAC so that these instructions would be recognized? 

Thank you for your help

    good to hear that it is working.  to get a full list of parameters for the FVP, run it with the command line argument "--list-params".   You will probably want to pipe the output to a text file.  This will show you all the configuration options for the Armv8-A model (and all the other models in the platform).
