In an aspect of the disclosure, a method, a computer-readable medium, and a computer system are provided. The computer system includes a service processor. The service processor monitors events of one or more ACPI compliant devices of a host of the service processor. The service processor maintains device data associated with the one or more ACPI compliant devices based on the events in a data store of the service processor. The service processor emulates an ACPI controller to monitor a communication channel for detecting one or more ACPI commands from the host. The service processor processes the device data in the data store in response to detecting the one or more ACPI commands on the communication channel.

Techniques of emulating an ACPI controller on a service processor

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a BMC. The BMC stores an extended SEL record entry in a data repository. The extended SEL record entry including a locator to a data collection stored external to the data repository. The BMC further retrieves the data collection based on the locator in response to receiving a request-to-retrieve-an-SEL-record.

A system includes a computing device and a server management controller configured to be connected to the computing device. The server management controller includes a processor, an interface in communication with multiple sensors disposed in the computing device, and a non-volatile memory storing computer executable code. The code, when executed at the processor, is configured to: assign each of the sensors with a logical unit number (LUN) and a sensor number; receive a first message from a first sensor of the sensors via the interface, where the first message has a first LUN field storing the assigned LUN and a first sensor number field storing the assigned sensor number of the first sensor; process the received first message; and determine the first sensor as a source of the first message based on the LUN and the sensor number stored in the first message.

System and method of supporting more than 256 sensors by intelligent platform management interface (IPMI) based server management controller

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a service processor. The service processor emulates a frame buffer. The service processor determines whether the service processor is configured to generate display signals to be sent to a display based on images from the service processor or based on images from a host of the service processor. When the service processor is configured to generate the display signals based on the images from the service processor, the service processor generates a first image based on serial data received from the host through a serial port, writes the first image to the emulated frame buffer, and generates a first display signal to be sent to the display based on the first image from the emulated frame buffer.

Techniques of displaying host data on a monitor connected to a service processor during pre-boot initialization stage

Certain aspects direct to a system having at most four service processors (SP's). Each of the at most four SP's is assigned with a logical unit number (LUN) of 0 to 3. When the SP receives a message packet, the SP identifies the message packet based on the header of the message packet. The header uses a LUN field to identify a corresponding SP as a destination of the message packet. For the LUN 0 SP, when the message packet is identified as a request message packet for the LUN 0 SP, the SP processes the request message packet to generate a corresponding response message packet. When the message packet is identified as a request message packet for other SP's (LUN 1-3), the SP saves a copy of the header of the request message packet for later response use, and forwards the request message packet to the destination.
