description: >
Implement the Soft Power Off function.
On receiving the SMS_ATTN from BMC, Host will respond with a
GetMessageFlags command and the BMC will respond with a static
data indicating that Event Message Buffer is full. Host then sends
'ReadEvent' command and BMC responds with an architected packet
mentioning that the type is SOFT_OFF. Host then goes ahead and starts
to quiesce. Once that is done, Host will send a hard
power off command to BMC and then BMC will issue a hard power off.
properties:
- name: ResponseReceived
type: enum[self.HostResponse]
default: NotApplicable
description: >
When the response is received for 'SMS_ATN', this is set to
'SoftOffReceived' and is set to 'HostShutdown' when Host
sends a Power Off request.
enumerations:
- name: HostResponse
description: >
Possible response types from Host for a Soft Power Off function.
values:
- name: NotApplicable
description: >
Default initial value.
- name: SoftOffReceived
description: >
Host has received the SMS_ATN from BMC indicating that
Host needs to do a Soft Power Off.
- name: HostShutdown
description: >
Host has sufficiently quiesced and acknowledged the shutdown
request such that the hardware shutdown sequence can safely
be performed.
