During PCH manufacturing a global reset has to be induced in order for configuration changes take affect upon following platform reset. This setting was commonly done by accessing PMC registers via /dev/mem but due to security concern /dev/mem access is much restricted, hence the reason for exposing this setting via dedicated sysfs interface. To prevent post manufacturing abuse the register is protected by hardware locking.
could you please define "manufacturing" ? The chip or board ? Is there any use for this, after the machine left the factory ? --mtx -- --- Hinweis: unverschlüsselte E-Mails können leicht abgehört und manipuliert werden !
