Yes, they are created automatically and you should not edit them
manually. Just have a look at the main Makefile:

qapi-modules =3D $(SRC_PATH)/qapi-schema.json $(SRC_PATH)/qapi/common.json \
               $(SRC_PATH)/qapi/block.json $(SRC_PATH)/qapi/block-core.json=
 \
               $(SRC_PATH)/qapi/event.json

qapi-types.c qapi-types.h :\
$(qapi-modules) $(SRC_PATH)/scripts/qapi-types.py $(qapi-py)
        $(call quiet-command,$(PYTHON) $(SRC_PATH)/scripts/qapi-types.py \
                $(gen-out-type) -o "." -b -i $<, \
                "  GEN   $@")

So if you want to change something in this area, you likely have to
touch the *.json files instead.
