ASID and VMID used to be uint16_t in the translation config, however, in other contexts they can be int as -1 in case of TLB invalidation, to represent all (don’t care). When stage-2 was added asid was set to -1 in stage-2 and vmid to -1 in stage-1 configs. However, that meant they were set as (65536), this was not an issue as nesting was not supported and no commands/lookup uses both. With nesting, it’s critical to get this right as translation must be tagged correctly with ASID/VMID, and with ASID=-1 meaning stage-2. Represent ASID/VMID everywhere as int.
