If vtype.vill=1, is VLMAX equal to 0? If vlamx=0, then any value configured for vstart is treated as an illegal instruction, because in this case, any vstart value is greater than the element index.

“The use of vstart values greater than the largest element index for the current SEW setting is reserved”
If vtype.vill=1, is VLMAX equal to 0? If vlamx=0, then any value configured for vstart is treated as an illegal instruction, because in this case, any vstart value is greater than the element index. Is my understanding correct?

Yes. (More accurately, vstart >= vl is reserved, not necessarily illegal, but in practice you have the right idea.)
