7 This document describes the impact of asymmetric 32-bit SoCs on the
8 execution of 32-bit (``AArch32``) applications.
10 Date: 2021-05-17
15 Some Armv9 SoCs suffer from a big.LITTLE misfeature where only a subset
16 of the CPUs are capable of executing 32-bit user applications. On such

21 64-bit-only CPU, then the onlining operation fails and the new CPU is
