Hi all,
I want the Guest OS to use the Arm-TF service in Host OS (It is the same as using Trusted Application in OP-TEE). So I should provide some parameters and call SMC instruction.
But it returns an "Undefined Instruction" in my Linux v4.9.51.
I find that KVM calls a " kvm_inject_undefined(vcpu);" when handling the SMC instruction.
So, if I want the Guest OS to use the "Arm-TF service" or "TA", should I simply change the kvm_inject_undefined() as "SMC #0", and carefully handle the input parameters? What else should I do?
Sincerely,
Wang Chenxu
