Changeset 11498:7a8fef12086e --------------------------- arm: Correctly check FP/SIMD access permission in aarch32 The current implementation of aarch32 FP/SIMD in gem5 assumes that EL1 and higher are all 32-bit. This breaks interprocessing since an aarch64 EL1 uses different enable/disable bits. This change updates the permission checks to according to what is prescribed by the ARM ARM.
