摘要： In accordance with certain other techniques, doorbell information is received. A doorbell structure address is decoded from the doorbell information. A first protection domain identifier is determined from the doorbell structure address. A resource context of a data structure is determined from the doorbell information. The resource context at the doorbell address is read to determine a second protection domain identifier. The first protection domain identifier and the second protection domain identifier are compared to determine whether to update the resource context of the doorbell structure.

摘要： Provided are techniques for interrupt processing. An Input/Output device determines that an event has occurred. The Input/Output device determines a state of an event data structure. The Input/Output device writes an event entry into the event data structure in response to determining that the event has occurred. After writing the event entry, the Input/Output device determines whether to generate an interrupt or not based on the state of the event data structure.Additionally provided are techniques for interrupt processing in which an I/O device driver determines that an interrupt has occurred. The I/O device driver reads an event entry in an event data structure in response to determining that the interrupt has occurred. The I/O device driver updates a state of a structure state indicator to enable/disable interrupts.

摘要： Provided are a method, system, and program for utilizing a virtualized data structure table such as an address translation and protection table (TPT), for example, in an I/O device. The virtualized data structure table has virtually contiguous data structures but not necessarily physically contiguous data structures in system memory. The data structure table may be accessed in a virtually contiguous manner. In the illustrated embodiment, the table is subdivided at a first hierarchal level into a plurality of virtually contiguous units or segments. Each unit or segment is in turn subdivided at a second hierarchal level into a plurality of virtually contiguous subunits, subsegments, pages or blocks. Each page or block is in turn subdivided at a third hierarchal level into a plurality of physically contiguous table entries. The data structure table may be accessed in a virtually contiguous manner utilizing a set of hierarchal data structure tables corresponding to the hierarchal levels of the data structure table.

摘要： A method and system for transmitting packets. Packets may be transmitted when a protocol control block is copied from a host processing system to a network protocol offload engine. Message information that contains packet payload addresses may be provided to the network protocol offload engine to generate a plurality of message contexts in the offload engine. With the message contexts, protocol processing may be performed at the offload engine while leaving the packet payload in the host memory. Thus, packet payloads may be transmitted directly from the host memory to a network communication link during transmission of the packets by the offload engine. Other embodiments are also described.

摘要： Provided are techniques for interrupt processing. An Input/Output device determines that an event has occurred. The Input/Output device determines a processor identifier and determines an event data structure identifier for an event data structure into which data for the event is stored using the processor identifier. The Input/Output device also determines a vector identifier for an interrupt message vector into which an interrupt message for the event is written. Then, interrupt message data is written to the interrupt message vector to generate an interrupt.

摘要： A platform may comprise a management controller (MC) and a BIOS that may store SMBIOS information that may comprise metadata. SMBIOS information may be stored in the SMBIOS structure table. SMBIOS information may be transferred to the MC and may be communicated from the MC to an entity external to the platform. The BIOS may be inaccessible to the external entity. The MC may communicate with the external entity when the platform is powered ON or OFF. SMBIOS information may be transferred between the BIOS and the MC via a communication link. The MC and/or the BIOS may determine whether SMBIOS information from the MC is up-to-date. SMBIOS information may be copied from the BIOS to the MC if not up-to-date. SMBIOS information may be transferred via SMBIOS messages based on structure type, instance ID and/or handle.
摘要翻译：平台可以包括可以存储可以包括元数据的SMBIOS信息的管理控制器（MC）和BIOS。 SMBIOS信息可能存储在SMBIOS结构表中。 SMBIOS信息可以被传送到MC，并且可以从MC传送到平台外部的实体。 BIOS可能无法访问外部实体。当平台通电或关闭时，MC可以与外部实体进行通信。 SMBIOS信息可以经由通信链路在BIOS和MC之间传送。 MC和/或BIOS可以确定来自MC的SMBIOS信息是否是最新的。 SMBIOS信息可以从BIOS复制到MC，如果不是最新的。 SMBIOS信息可以通过基于结构类型，实例ID和/或句柄的SMBIOS消息传输。
