However we never actually use the TLB -- all stage 2 lookups are done by direct calls to get_phys_addr_lpae() followed by a physical address load via address_space_ld*(). Remove Stage2 from the list of ARM MMU indexes which correspond to real core MMU indexes, and instead put it in the set of "NOTLB" ARM MMU indexes. This allows us to drop NB_MMU_MODES to 11. It also means we can safely add support for the ARMv8.3-TTS2UXN extension, which adds permission bits to the stage 2 descriptors which define execute permission separatel for EL0 and EL1; supporting that while keeping Stage2 in a QEMU TLB would require us to use separate TLBs for "Stage2 for an EL0 access" and "Stage2 for an EL1 access", which is a lot of extra complication given we aren't even using the QEMU TLB.

For ID_AA64DFR0 we accidentally used 'u', meaning that the top 32 bits of this 64-bit ID register would end up always zero.

In order to share the decode files between A32 and T32, we split Neon into 3 parts: * data-processing * load-store * 'shared' encodings The first two groups of instructions have similar but not identical A32 and T32 encodings, so we need to manually transform the T32 encoding into the A32 one before calling the decoder; the third group covers the Neon instructions which are identical in A32 and T32.

This is an Armv9.0-A processor very similar to the Cortex-A710. The differences are: * no FEAT_EVT * FEAT_DGH (data gathering hint) * FEAT_NV (not yet implemented in QEMU) * Statistical Profiling Extension (not implemented in QEMU) * 48 bit physical address range, not 40 * CTR_EL0.DIC = 1 (no explicit icache cleaning needed) * PMCR_EL0.N = 6 (always 6 PMU counters, not 20) Because it has 48-bit physical address support, we can use this CPU in the sbsa-ref board as well as the virt board.

Instead of reporting a correct full syndrome value with the EC and IL bits, we only reported the low two bits of the syndrome, because the call to syn_erettrap() got dropped.
