Watchdog
For BIOS and OS Agent watchdog, this system adopts standard design as specified IPMI 1.5, but for OS Load watchdog.
These enable, disable, interval time and action are controlled by OEM Set BIOS/OS Load WD Action Info command. All
this data will be kept inside BMC NV memory.
Pre-Timeout Interrupt Support
For watchdog pre-timeout’s interrupt, BMC supports SMI and NMI, and SMI is used in BIOS implementation already, so use
watchdog with pre-timeout SMI is not recommended.
Timeout Action Support
For watchdog timeout action, BMC supports power down, power cycle and power reset.
