Subject: [PATCH] Enable watchdog to save useflag after host power off
Get the right useflag after host power off.
Tested:
Set a watchdog (Timer action is none and Time Use is BIOS FRB2)
ipmitool raw 0x06 0x24 0x01 0x00 0x00 0x00 0x40 0x00
Get watchdog
ipmitool mc watchdog get
Start watchdog
ipmitool mc watchdog reset
Get watchdog
ipmitool mc watchdog get
After timer is stop, set a watchdog again
(Timer action is none and Time Use is BIOS/POST)
ipmitool raw 0x06 0x24 0x02 0x00 0x00 0x00 0x40 0x00
Start watchdog and wait until timer is stop,
Get watchdog
ipmitool mc watchdog get
Timer Expiration Flags should be 0x06(BIOS FRB2, BIOS/POST)
Power down the Host
Ipmitool chassis power off
Check the Timer Expiration Flags(User Flags)
ipmitool mc watchdog get
Timer Expiration Flags should be 0x06(BIOS FRB2, BIOS/POST)
