Subject: APM & ACPI detect

Hi,

Are there any "official way" to detect that APM or ACPI is active?

With APM I try it and it works:

#ifdef CONFIG_APM
#include <linux/apm_bios.h>
#endif

...

#ifdef CONFIG_APM
if (apm_info.disabled >= 0) {
printk(KERN_NOTICE "Real APM support is present.\n");
}
#endif

Are there any similar for ACPI?

Thanks,
Peter

Well there's pm_active, which is 1 if either is on. Is this really what you
want?

No, I have to know what stuff is active: APM or ACPI.

OK, I guess we'll add that.
