From c0177f911f205b3f007df64fbc66fa0ff07caf8e Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Tue, 11 Apr 2023 15:35:10 -0300 Subject: target/riscv: add query-cpy-definitions support This command is used by tooling like libvirt to retrieve a list of supported CPUs. Each entry returns a CpuDefinitionInfo object that contains more information about each CPU. This initial support includes only the name of the CPU and its typename. Here's what the command produces 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": false, "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": false, "deprecated": false}, {"name": "thead-c906", "typename": "thead-c906-riscv-cpu", "static": false, "deprecated": false}, {"name": "sifive-u54", "typename": "sifive-u54-riscv-cpu", "static": false, "deprecated": false}] } Next patch will introduce a way to tell whether a given CPU is static or not.
