Firmware-related event notification

摘要

This disclosure is directed to firmware-related event notification. A device may comprise an operating system (OS) configured to operate on a platform. During initialization of the device a firmware module in the platform may load at least one globally unique identifier (GUID) into a firmware configuration table. When the platform notifies the OS, the firmware module may load at least one GUID into a platform notification table and may set a platform notification bit in a platform notification table status field. Upon detecting the notification, an OS management module may establish a source of the notification by querying the platform notification table. The platform notification bit may cause the OS management module to compare GUIDs in the platform notification table and the firmware configuration table. Services may be called based on any matching GUIDs. If no GUIDs match, the services may be called based on firmware variables in the device.

主权项

1. A device to generate firmware-related event notifications, comprising:
memory circuitry including at least a shared memory space; a firmware module to:
load at least part of a messaging interface into the shared memory space;load at least one globally unique identifier into a platform notification table in the shared memory space;set at least one platform notification bit in a status field of the platform notification table; andcause the messaging interface to generate a notification to an operating system in the device; and processor circuitry to perform operations in the device based at least on instructions received from the operating system, the operating system including an operating system management module to at least react to the notification presented by the messaging interface.
