IpmiFeaturePkg

This package contains core code and features for leveraging IPMI in UEFI. For details on the design of the IPMI package see the IPMI feature documentation.

Configuring the IPMI package

The IPMI feature package is designed to be customizable to fit the needs of the platform. This can be done through a combination of platform libraries and PCD settings.

Important PCDs

For the full list of PCDs, see the package DEC file.

  • Generic IPMI
    • PcdIpmiCheckSelfTestResults - Indicates the self-test command should be queried for IPMI initialization.
    • PcdIpmiCommandTimeoutSeconds - Timeout for IPMI command response.
    • PcdBmcTimeoutSeconds - Timeout for initial BMC initialization.
  • IPMI Watchdog
    • PcdFrb2EnabledFlag - Enables use of the FRB2 watchdog for UEFI boot.
    • PcdFrb2TimeoutSeconds - FRB2 timeout in seconds.
    • PcdFrb2TimeoutAction - Action taken on FRB2 timeout.
    • PcdOsWatchdogEnabled - Enables the OS watchdog at exit boot services.
    • PcdOsWatchdogTimeoutSeconds - The timeout for the OS watchdog in seconds.
    • PcdOsWatchdogAction - Action taken on OS watchdog timeout.
  • SEL Library
    • PcdIpmiSelOemManufacturerId - The manufacturer ID used in OEM SEL events.

Platform Libraries

The primary location for platform customization of the generic IPMI code is in the IPMI Platform library. If the system requires special initialization logic, self-test handling, IO port configuration, etc, then it should be done by implementing this library.

Additionally the platform may choice to implement their own IPMI transport library for a non-standard communication method wth the BMC.

Samples

The samples directory in this package is intended to provide examples of common usage of the IPMI package components that are not suitable for generic implementation. Platforms may choose to use these as a starting point or reference for implementing similar functionality, but these implementations cannot be used as-is.
