Hi Alexei,

We are trying to test this on the tegra platforms. The patches you share seem to be for fvp.

Is there any tftf test for this? Or Any guidance on porting the test?

Thanks,

kalyani

Hi,

Is there any test to verify the BP_OPTION feature set to “pac-ret+leaf” ?

When BRANCH_PROTECTION is set to “3”, BP_OPTION is set to “pac-ret+leaf”.

Thanks,

Kalyani
