| Patrick Williams | a1bd285 | 2022-12-08 06:12:43 -0600 | [diff] [blame] | 2 | Implement the Soft Power Off function. On receiving the SMS_ATTN from BMC, |
| 3 | Host will respond with a GetMessageFlags command and the BMC will respond |
| 4 | with a static data indicating that Event Message Buffer is full. Host then |
| 5 | sends 'ReadEvent' command and BMC responds with an architected packet |
| 6 | mentioning that the type is SOFT_OFF. Host then goes ahead and starts to |
| 7 | quiesce. Once that is done, Host will send a hard power off command to BMC |
| 8 | and then BMC will issue a hard power off. |
