hw: Add a Kconfig switch for the TYPE_CPU_CLUSTER device

2024-04-25T10:48:12Z

The cpu-cluster device is only needed for some few arm and riscv machines. Let's avoid compiling and linking it if it is not really necessary.

hw: Fix problem with the A*MPCORE switches in the Kconfig files

2024-04-25T10:48:12Z

A9MPCORE, ARM11MPCORE and A15MPCORE are defined twice, once in hw/cpu/Kconfig and once in hw/arm/Kconfig. This is only possible by accident, since hw/cpu/Kconfig is never included from hw/Kconfig. Fix it by declaring the switches only in hw/cpu/Kconfig (since the related files reside in the hw/cpu/ folder) and by making sure that the file hw/cpu/Kconfig is now properly included from hw/Kconfig.

target/arm: Move GTimer definitions to new 'gtimer.h' header

2024-01-26T11:30:49Z

Move Arm A-class Generic Timer definitions to the new "target/arm/gtimer.h" header so units in hw/ which don't need access to ARMCPU internals can use them without having to include the huge "cpu.h".

hw/cpu/a9mpcore: Build it only once

2024-01-26T11:30:48Z

hw/cpu/a9mpcore.c doesn't require "cpu.h" anymore. By removing it, the unit become target agnostic: we can build it once. Update meson. Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Richard Henderson Message-id: 20240118200643.29037-13-philmd@linaro.org Signed-off-by: Peter Maydell

Remove unused header (qemu/module.h and qemu/cutils.h) in cluster.c, and reorder the remaining header files (except qemu/osdep.h) in alphabetical order. Tested by "./configure" and then "make".

meson: Replace softmmu_ss -> system_ss

2023-06-20T08:01:30Z

We use the user_ss[] array to hold the user emulation sources, and the softmmu_ss[] array to hold the system emulation ones. Hold the latter in the 'system_ss[]' array for parity with user emulation. Mechanical change doing: $ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss) Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Richard Henderson Message-Id: <20230613133347.82210-10-philmd@linaro.org> Signed-off-by: Richard Henderson

hw/cpu: Mark arm11 and realview mpcore as target-independent code

2023-01-16T16:51:20Z

Seems like there is nothing target-specific in here, so these files can be moved to softmmu_ss to avoid that they get compiled twice (once for qemu-system-arm and once for qemu-system-aarch64).

cpu/core: Fix "help" of CPU core device types

2021-04-09T20:05:16Z

Calling qdev_get_machine() from a QOM instance_init function is fragile because we can't be sure the machine object actually exists. And this happens to break when passing ",help" on the command line to get the list of properties for a CPU core device types : $ ./qemu-system-ppc64 -device power8_v2.0-spapr-cpu-core,help qemu-system-ppc64: ../../hw/core/machine.c:1290: qdev_get_machine: Assertion `machine != NULL' failed. Aborted (core dumped) This used to work before QEMU 5.0, but commit 3df261b6676b unwillingly introduced a subtle regression : the above command line needs to create an instance but the instance_init function of the base class calls qdev_get_machine() before qemu_create_machine() has been called, which is a programming bug. Use current_machine instead. It is okay to skip the setting of nr_thread in this case since only its type is displayed.
