No, I meant static tcg_enabled as the kvm_enabled() earlier method:
static bool kvm_enabled(QTestState *qts)
{
QDict *resp, *qdict;
bool enabled;
resp = qtest_qmp(qts, "{ 'execute': 'query-kvm' }");
g_assert(qdict_haskey(resp, "return"));
qdict = qdict_get_qdict(resp, "return");
g_assert(qdict_haskey(qdict, "enabled"));
enabled = qdict_get_bool(qdict, "enabled");
qobject_unref(resp);
return enabled;
}
This should be moved to something generic to QTest IMO,
and we need some runtime qtest_is_accelerator_enabled().
