2021-07-09accel: autoload modulesGerd Hoffmann1-1/+1
Call module_object_class_by_name() instead of object_class_by_name() for objects possibly implemented as module Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Jose R.

2021-05-10accel: add init_accel_cpu for adapting accel behavior to CPU typeClaudio Fontana1-0/+13
while on x86 all CPU classes can use the same set of TCGCPUOps, on ARM the right accel behavior depends on the type of the CPU. So we need a way to specialize the accel behavior according to the CPU. Therefore, add a second initialization, after the accel_cpu->cpu_class_init, that allows to do this.

2021-05-10accel-cpu: make cpu_realizefn return a boolClaudio Fontana1-3/+3
overall, all devices' realize functions take an Error **errp, but return void. hw/core/qdev.c code, which realizes devices, therefore does: local_err = NULL; dc->realize(dev, &local_err); if (local_err != NULL) { goto fail; } However, we can improve at least accel_cpu to return a meaningful bool value.

2021-05-10accel: introduce new accessor functionsClaudio Fontana1-0/+19
avoid open coding the accesses to cpu->accel_cpu interfaces, and instead introduce: accel_cpu_instance_init, accel_cpu_realizefn to be used by the targets/ initfn code, and by cpu_exec_realizefn respectively.

2021-02-05accel: introduce AccelCPUClass extending CPUClassClaudio Fontana1-0/+44
add a new optional interface to CPUClass, which allows accelerators to extend the CPUClass with additional accelerator-specific initializations. This will allow to separate the target cpu code that is specific to each accelerator, and register it automatically with object hierarchy lookup depending on accelerator code availability, as part of the accel_init_interfaces() initialization step.

2021-02-05accel: replace struct CpusAccel with AccelOpsClassClaudio Fontana1-0/+11
This will allow us to centralize the registration of the cpus.c module accelerator operations (in accel/accel-softmmu.c), and trigger it automatically using object hierarchy lookup from the new accel_init_interfaces() initialization step, depending just on which accelerators are available in the code. Rename all tcg-cpus.c, kvm-cpus.c, etc to tcg-accel-ops.c, kvm-accel-ops.c, etc, matching the object type names.
