6.3.5.1 Processing Sequence for Graceful Shutdown Request:
Following receipt of the Graceful Shutdown Request (see Table 5-142, value 0x0C) the OS will be
responsible for responding with one of the following status codes:
• 0x80 (OS Shutdown Request denied) –This value will be sent if the OS is not capable of
performing a graceful shutdown.
• 0x81 (OS Shutdown in progress) – The OS has initiated the graceful shutdown procedure.
• 0x83 (OS Graceful Shutdown not supported) – The OS does not support the Graceful Shutdown
Request.
If the OS does initiate a graceful shutdown it should continue to generate the “OS Shutdown in
progress” message (_OST source event 0x100 status code 0x81) every 10 seconds. This functions as
a heartbeat so that the service which requested the graceful shutdown knows that the request is
currently being processed. The platform should assume that the OS shutdown is not proceeding if it
does not receive the “OS Shutdown in progress” message for 60 seconds.
When the graceful shutdown procedure has completed the OSPM will send the “OS Shutdown
completed” message and then transition the platform to the G2 “soft-off” power state.
