Hi Kalyani,

There is tf-a-tests\tftf\tests\extensions\pauth\test_pauth.c which tests that PAuth keys were preserved and restored correctly when switching to/from Secure World. You can also take a look at test configurations I referenced and work out what BP_OPTION options should be set for your tegra platform and use TFTF for testing.

Regards.

Alexei

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”.

Reference code - https://github.com/ARM-software/arm-trusted-firmware/blob/master/Makefile

Thanks,

Kalyani
