Abstract: Examples described herein relate to updating boot firmware code or microcode. In some examples, a management controller includes a memory and a system processor, coupled to the management controller, is to: based on a first configuration, perform a boot operation by a read of first boot firmware code from the memory of the management controller. Based on a second configuration, the system processor is to perform a boot operation by a read of second boot firmware code from a flash memory.

Abstract: Examples include updating firmware for a persistent memory module in a computing system during runtime. Examples include copying a new version of persistent memory module firmware into an available area of random-access memory (RAM) in the persistent memory module, and transferring processing of a current version of persistent memory module firmware to the new version of persistent memory module firmware during runtime of the computing system, without a reset of the computing system and without quiesce of access to persistent memory media in the persistent memory module, while continuing to perform critical event handling by the current version of persistent memory module firmware.

Abstract: Examples include updating firmware for a persistent memory module in a computing system during runtime. Examples include downloading firmware to the persistent memory module; saving settings of one or more input/output (I/O) devices of the computing system and setting a timeout value of the one or more I/O devices to greater than a time to activate the firmware in the persistent memory module. Examples include updating the firmware in the persistent memory module during runtime of the computing system by quiescing access to one or more memory modules of the computing system; sending a request to the persistent memory module to activate the firmware; waiting for the request to activate the firmware to be completed by the persistent memory module; and un-quiescing access to the one or more memory modules of the computing system; and restoring the saved settings for the one or more I/O devices.

Abstract: Examples described herein relate to a network interface receiving a firmware update from one or more packets. In some examples, the one or more packets indicate a start of a firmware update. In some examples, the network interface can also perform authenticating the start of firmware update indication and based on authentication of the firmware update, permit a firmware update of a device. In some examples, the device is one or more of: Board Management Controller (BMC), central processing unit (CPU), network interface, Ethernet controller, storage controller, memory controller, display engine, graphics processing unit (GPU), accelerator device, or peripheral device. In some examples, an end of firmware update indicator is received in the one or more packets. In some examples, communications are maintained through a port during a firmware change.

Abstract: Apparatuses, methods and storage media for communications between a peripheral device and host device in the absence of established connection between the devices are described. In one instance, an apparatus may include a host processor, a memory, and a controller coupled with the host processor and the memory and configured to detect for a communication broadcasted via an advertising channel by a peripheral device; determine whether a unique identifier previously communicated to the peripheral device is present in the detected communication; and provide a message corresponding to the communication to the host processor for processing, based on a result of the determination. The apparatus communicates with the peripheral device via a connection established over communication channels. The advertising channel and the communication channels are different. The connection between the devices is not established when the communication is broadcasted via the advertising channel.
