qemu-system-arm: unknown type 'cortex-a35-arm-cpu'
[Exit 1 ]
Same for ast2700-a2.
I found the folllowing in their .instance_init() method
aspeed_soc_ast2700_init():
for (i = 0; i < sc->num_cpus; i++) {
if (qtest_enabled() && !target_aarch64()) {
/*
* Introspection qtest just want to create this object
* without realizing it. ARM_CPU_TYPE_NAME("cortex-a35")
* is not available on 32-bit binary: skip it since we
* won't even realize it.
*/
continue;
}
object_initialize_child(obj, "cpu[*]", &a->cpu[i],
aspeed_soc_cpu_type(sc->valid_cpu_types));
}
This seems to paper over the bug so make the tests pass. That's wrong.
.instance_init() must not fail and must not exit(), regardless of
context.
object_initialize_child() exit()s when the type doesn't exist, because
&error_fatal gets passed to in type_get_or_load_by_name() in
object_initialize_child().
The narrow fix is to make type "cortex-a35-arm-cpu" exist, or to make
the two bad types "ast2700-a1" and "ast2700-a2" not exist.
