acpi_init什么时候调用的？定义在哪个位置？

static int __init acpi_init(void)

{

int result;

if (acpi_disabled) {

printk(KERN_INFO PREFIX "Interpreter disabled.\n");

return -ENODEV;

}

acpi_kobj = kobject_create_and_add("acpi", firmware_kobj);

if (!acpi_kobj) {

printk(KERN_WARNING "%s: kset create error\n", __func__);

acpi_kobj = NULL;

}

init_acpi_device_notify();

result = acpi_bus_init();

if (result) {

disable_acpi();

return result;

}

pci_mmcfg_late_init();

acpi_scan_init();

acpi_ec_init();

acpi_debugfs_init();

acpi_sleep_proc_init();

acpi_wakeup_device_init();

pr_err("acpi_init... \n");/*我自己加的*/

return 0;

}

subsys_initcall(acpi_init);
