Time Sync
In BMC design, BMC does not have a local RTC to know what time it is. Each time BMC will
get the current time from system PCH after BMC boot. The current time is updated period-
ically from the PCH. The remote console program interpret this time as pre-initial.
SEL
BMC supports IPMI 1.5/2.0 standard SEL operation. It can keep SEL log. Event happened in
BIOS side will be logged by using Add SEL Entry command. BMC will store them in FLASH,
the time stamp field will be filled by BMC. When SEL is full, the new SEL won’t be logged
but will go through PEF as usual. If AC powers off, all SELs will remain in NV.
Platform Event
Platform Event Filter
The BMC implements selectable action on an event or LAN alerting base on event. By
default, no any PEF entries or actions exist, applications need to configure it to enable.
Dedicated and Shared NIC
The policy to match an event to Platform Event Filter Table entry is IPMI 1.5 standard.
The action support Power off, Power Reset, Power Cycle and NMI.
All Platform Event Filter Table is default disabled.
PEF Startup Delay and Last Processed Event tracking is not supported.
PEF table lookup isn’t correlated to log SEL to SEL Repository.
Serial Alerting is no support.
