This series bases on Phil's repository because the prepatory commits have been queued to the branch.
https://gitlab.com/philmd/qemu.git (branch: cpus-next) There are two places where the user specified CPU type is checked to see if it's supported or allowed by the board: machine_run_board_init() and mc->init(). We don't have to maintain two duplicate sets of logic. This series intends to move the check to machine_run_board_init() so that we have unified CPU type check. PATCH[1-3] refactors the logic to validate CPU type in machine_run_board_init() PATCH[4-8] validates the CPU type in machine_run_board_init() for the individual boards v1: https://lists.nongnu.org/archive/html/qemu-arm/2023-07/msg00302.html v2: https://lists.nongnu.org/archive/html/qemu-arm/2023-07/msg00528.html v3: https://lists.nongnu.org/archive/html/qemu-arm/2023-09/msg00157.html v4: https://lists.nongnu.org/archive/html/qemu-arm/2023-11/msg00005.html v5: https://lists.nongnu.org/archive/html/qemu-arm/2023-11/msg00611.html Testing ======= With the following command lines, the output messages are varied before and after the series is applied. ./build/qemu-system-aarch64 \ -accel tcg -machine virt,gic-version=3 \ -cpu cortex-a8 -smp maxcpus=2,cpus=1 Before the series is applied: qemu-system-aarch64: mach-virt: CPU type cortex-a8-arm-cpu not supported After the series is applied: qemu-system-aarch64: Invalid CPU type: cortex-a8-arm-cpu The valid models are: cortex-a7, cortex-a15, cortex-a35, cortex-a55, cortex-a72, cortex-a76, a64fx, neoverse-n1, neoverse-v1, cortex-a53, cortex-a57, max Changelog ========= v6: * Drop PATCH[v5 01-23], queued by Phil (Phil) * Clearer hint if only one CPU type is supported and have 'const MachineState *' in is_cpu_type_supported() (Phil) * Move valid_cpu_types[] to board's class_init() function (Phil) v5: * PATCH[v5 01] to remove CPU class 'ev67' for alpha (Ricard/Igor) * PATCH[v5 02] to remove object_class_is_abstract() for hppa (Gavin) * Don't move cpu_class_by_name() (Richard) * PATCH[v5 04] to remove 'oc == NULL' since the check has been covered in object_class_dynamic_cast() (Igor) * Introduce generic cpu_list(), shared by most of the targets (Richard) * Use g_str_has_suffix and g_auto_free (Richard) * Collect r-bs from Igor and Richard (Gavin) v4: * Integrate Philippe's patches where cpu_class_by_name() is consolidated and my duplicate code is dropped (Philippe) * Simplified changelog and improvements (Thomas) * g_assert() on the return value from cpu_model_from_type() in is_cpu_type_supported() (Philippe) * Collected r-bs from Philippe Mathieu-Daudé, Leif Lindholm, Bastian Koppelmann, Daniel Henrique Barboza, Cédric Le Goater, Gavin Shan (Gavin) v3: * Generic helper cpu_model_from_type() (Igor) * Apply cpu_model_from_type() to the individual targets (Igor) * Implement cpu_list() for the missed targets (Gavin) * Remove mc->valid_cpu_models (Richard) * Separate patch to constify mc->validate_cpu_types (Gavin) v2: * Constify mc->valid_cpu_types (Richard) * Print the supported CPU models, instead of typenames (Peter) * Misc improvements for the hleper to do the check (Igor) * More patches to move the check (Marcin) Gavin Shan (8): machine: Use error handling when CPU type is checked machine: Introduce helper is_cpu_type_supported() machine: Print CPU model name instead of CPU type hw/arm/virt: Hide host CPU model for tcg hw/arm/virt: Check CPU type in machine_run_board_init() hw/arm/sbsa-ref: Check CPU type in machine_run_board_init() hw/arm: Check CPU type in machine_run_board_init() hw/riscv/shakti_c: Check CPU type in machine_run_board_init() hw/arm/bananapi_m2u.c | 12 ++--- hw/arm/cubieboard.c | 12 ++--- hw/arm/mps2-tz.c | 26 ++++++++--- hw/arm/mps2.c | 26 ++++++++--- hw/arm/msf2-som.c | 12 ++--- hw/arm/musca.c | 12 +++-- hw/arm/npcm7xx_boards.c | 12 +++-- hw/arm/orangepi.c | 12 ++--- hw/arm/sbsa-ref.c | 36 +++++---------- hw/arm/virt.c | 60 ++++++++++--------------- hw/core/machine.c | 97 +++++++++++++++++++++++++---------------- hw/riscv/shakti_c.c | 13 +++--- 12 files changed, 173 insertions(+), 157 deletions(-) -- 2.41.0
