9.3.1 Payload Driven Sensors
The IPMC firmware provides Firmware Progress, OS Boot, Boot Initiated, Memory, Battery,
Critical IRQ and Boot Error sensors to enable payload firmware and payload OS to report boot
progress/failure via IPMI event messages.
The firmware progress sensor implemented with sensor type
0x0F
(System Firmware
Progress) is used to pass payload boot progress information to the IPMC.
The OS Boot sensor implemented with sensor type
0x1F
(OS Boot) is used to inform the IPMC
when the operating system has completed its boot up sequence.
The Boot Initiated sensor implemented with sensor type
0x1D
(System Boot Initiated) is used
to give additional information about how the boot-up sequence is initiated (by hard reset, by
soft reset, and so on).
The Memory sensor implemented with sensor type
0x0C
(Memory) is used to inform the IPMC
about defect DIMMs detected during power-up.
The Battery sensor implemented with sensor type
0x29
(Battery) is used to inform the IPMC
about low/failed RTC.
The Critical IRQ sensor implemented with sensor type
0x13
(Critical Interrupt) is used to give
PCI errors and NMIs.
The boot error sensor implemented with sensor type
0x1E
(Boot Error) is used to pass boot
failure information to the IPMC.
In all cases above, the IPMC sends an event to the ShMM.
9.3.2 Boot Bank Supervision Sensor
The boot bank supervision sensor is intended to always give the actual boot bank from which
the payload has booted last.
