摘要： 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.

摘要： 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.

摘要： 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.

摘要： The disclosure relates to system event assisted live video capture. A baseboard management controller (BMC) allocates, in its available memory space of the memory, a first video block and a first node having a video block pointer and a next node pointer, and assigns the video block pointer of the first node to indicate the first video block. The BMC captures video frames of the host computer, and stores frame data and a timestamp generated from each frame in the first video block. When the first video block is full, the BMC allocates a second video block and a second node, and assigns the next node pointer of the first block to indicate the second node, and the video block pointer of the second node to indicate the second video block. The BMC then stores the frame data and the timestamp in the second video block.

摘要： 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.

摘要： Systems and methods to control a controller, such as a baseboard management controller (BMC), and its host computer with voice. The system may include a mobile device, which is communicatively connected to the controller via a network. The mobile device may receive a voice input, and generate a corresponding instruction by performing voice recognition to the voice input. The instruction may be sent to the controller for controlling the controller or its host computer. For example, the controller may perform a corresponding operation based on the instruction to determine whether the instruction is for the controller or for the host computer. When the instruction is for the host computer, in response to determining the target as the host computing device, the controller may perform keyboard-video-mouse (KVM) redirection to redirect the instruction to the host computer.
