Hardware Platform Interface - Resource-level Capabilities

Resource-level Capabilities

In addition to a set of Management Instruments as described above, an HPI Resource may also provide up to four additional management capabilities. These Resource-level capabilities are essentially special Management Instruments, of which there may be at most one of each type supported by a Resource. Whether or not a particular Resource provides these miscellaneous capabilities and to which Entity they apply are described in a data record accessible by the HPI user for the Resource. A single Entity Path is defined in that record, so any of these capabilities, if present, will apply to the same Entity.

• The resource-level Power Management capability acts as a specialized Control to turn power on or off the designated Entity.
• The resource-level Reset capability acts as a specialized Control to cause a hard or soft reset operation on the designated Entity, or if supported, to hold the reset signal in an asserted state to prevent the Entity from operating.
• The resource-level Load Management capability acts as a specialized Control that interfaces with the bootstrap program of the designated Entity to identify which operating system or other software should be loaded when a bootstrap operation is performed.
• The Resource-level Configuration Management capability provides a method for an HPI user to direct the Resource to save or restore configuration information, such as sensor threshold levels to or from a persistent storage medium.
