Abstract: Methods and systems for managing communications is disclosed. A host device and a management controller may communicate via memory mapped communications using shared memory. To improve the security of the memory mapped communications, access requests for shared memory may be monitored. Access controls for the shared memory may be put in place to reduce the likelihood of data being made unavailable before it is processed. The access controls may be lifted when the data stored in shared memory has been read by to complete the memory mapped communications.

Abstract: Methods and systems for managing the operation of data processing systems are disclosed. A data processing system may include a computing device that may enter various operating states by performing various types of startups. Performance of some startups may be restricted by use of passwords or other security information. The data processing systems may host management controllers that may bypass the restrictions on the startups. Prior to doing so, the management controllers may verify that the requests to perform the startups are from trusted entities, or should be performed for other reasons.

Abstract: Methods and systems for managing the operation of host devices is disclosed. A host device may include a computing device that operates in accordance with operation data. The operation data may include, for example, startup data such as code for a management entity (e.g., a basic input output system), settings (e.g., hardware and/or software) for the startup management entity, setting for general operation after booting to an operating system, copies of code (e.g., computer instructions executable with a processor) for applications to be executed by the host device, etc. If the operation data is modified, operation of the host device may be similarly modified.

Abstract: An information handling system may detect fan blockage for one or more fans using a target value such as the rotational rate of a fan or a duty cycle value of the pulse width modulation (PWM) signal for a fan, and a monitored value includes at least the other one of the rotational rate of the fan or the duty cycle value of the PWM signal for the fan. The information handling system may determine whether either the duty cycle value of the PWM signal for a fan or the rotational rate of the fan meets or crosses a threshold value. The threshold value, for example, may include an intake blocking warning limit or a rotational rate limit. The information handling system may then generate a notification to the user, such as a re-positioning notification. The methods described or illustrated may be entirely implemented in an embedded controller.

Abstract: An inter-integrated circuit (I2C) bus priority alert system includes sender device with a sender I2C connector. The sender device detects a first priority event and, in response, sends a first priority event alert signal through the sender I2C connector. A receiver device includes a receiver I2C connector that is connected to the sender I2C connector on the sender device over an I2C bus. The receiver device receives the first priority event alert signal from the sender device over the I2C bus and, in response, pauses a current data transmission operation that is being performed over the I2C bus. The receiver device then performs a first priority event action associated with the first priority event alert signal that addresses the first priority event such that no further actions are performed by the receiver device to address the first priority event. The receiver device may then resume the current data transmission operation.
