The register definitions for VMIDR and VMPIDR have separate reginfo structs for the AArch32 and AArch64 registers. However the 32-bit versions are wrong: * they use offsetof instead of offsetoflow32 to mark where the 32-bit value lives in the uint64_t CPU state field * they don't mark themselves as ARM_CP_ALIAS In particular this means that if you try to use an Arm guest CPU which enables EL2 on a big-endian host it will assert at reset: target/arm/cpu.c:114: cp_reg_check_reset: Assertion `oldvalue == newvalue' failed. because the reset of the 32-bit register writes to the top half of the uint64_t. Correct the errors in the structures. Backports commit 36476562d57a3b64bbe86db26e63677dd21907c5 from qemu |
