Hi, Referring https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/getti… it says : ``FAULT_INJECTION_SUPPORT``: ARMv8.4 extensions introduced support for fault injection from lower Els. Referring https://github.com/ARM-software/arm-trusted-firmware/blob/master/lib/el3_ru… FAULT_INJECTION_SUPPORT enables FIEN bit. #if FAULT_INJECTION_SUPPORT /* Enable fault injection from lower ELs */ scr_el3 |= SCR_FIEN_BIT; #endif Question : 1. Do we have any relevant documentation from arm which specifies FIEN bit can be enabled from armv8.4 ? 2. In cortex a-53 technical reference manual, SCR_EL3 does not have FIEN bit , bit 21 is marked reserved . In cortex a-78 technical reference manual , manual does not have details for SCR_EL3 . I want to know whether on Armv8.2-a based cores like cortex a-78 , is the FIEN bit field marked reserved in SCR_EL3 register or is available functionality wise as in armv8.4 ? Please help with above query. Regards Amit
