target/riscv: add TYPE_RISCV_DYNAMIC_CPU This new abstract type will be used to differentiate between static and non-static CPUs in query-cpu-definitions. All generic CPUs were changed to be of this type. Named CPUs are kept as TYPE_RISCV_CPU and will still be considered static. This is the output of query-cpu-definitions after this change for the riscv64 target: $ ./build/qemu-system-riscv64 -S -M virt -display none -qmp stdio {"QMP": {"version": (...)} {"execute": "qmp_capabilities", "arguments": {"enable": ["oob"]}} {"return": {}} {"execute": "query-cpu-definitions"} {"return": [ {"name": "rv64", "typename": "rv64-riscv-cpu", "static": false, "deprecated": false}, {"name": "sifive-e51", "typename": "sifive-e51-riscv-cpu", "static": true, "deprecated": false}, {"name": "any", "typename": "any-riscv-cpu", "static": false, "deprecated": false}, {"name": "x-rv128", "typename": "x-rv128-riscv-cpu", "static": false, "deprecated": false}, {"name": "shakti-c", "typename": "shakti-c-riscv-cpu", "static": true, "deprecated": false}, {"name": "thead-c906", "typename": "thead-c906-riscv-cpu", "static": true, "deprecated": false}, {"name": "sifive-u54", "typename": "sifive-u54-riscv-cpu", "static": true, "deprecated": false} ]} Suggested-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Daniel Henrique Barboza <dbarboza@ventanamicro.com> Acked-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20230411183511.189632-4-dbarboza@ventanamicro.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>
