[PATCH] hw/arm/smmuv3: Fix addr_mask for range-based invalidation

When performing range-based IOTLB invalidation, we should decode the TG field into the corresponding translation granule size so that we can pass the correct invalidation range to backend. Set @granule to (tg * 2 + 10) to properly emulate the architecture. Fixes: d52915616c05 ("hw/arm/smmuv3: Get

[PATCH 04/16] tcg/s390x: Add host vector framework

Add registers and function stubs. The functionality is disabled via squashing s390_facilities[2] to 0. We must still include results for the mandatory opcodes in tcg_target_op_def, as all opcodes are checked during tcg init. Signed-off-by: Richard Henderson --- tcg/s390x/tcg-target-conset.h |
