Is it possible to access the function API compiled in AARCH32 execution state (EL0/EL1) from AARCH64 bit execution space (EL1/EL2/EL3) space in ARMv8 processor?
To be precise: Not by direct call. IIRC you need to switch from AArch64 to AArch32 by way of an exception, do the AArch32 call and then return from exception.
