摘要： This is directed to methods and systems for handling access requests from a device to a host. The device may be a device that is part of the host, such as an HBA, an NIC, etc. The device may include a processor which runs firmware and which may generate various host access requests. The host access requests may be, for example, memory access requests, or DMA requests. The device may include a module for executing the host access requests, such as a data transfer block (DXB). The DXB may process incoming host access requests and return notifications of completion to the processor. For various reasons, the processor may from time to time issue null or zero length requests. Embodiments of the present invention ensure that the notifications of completion for all requests, including the zero length requests, are sent to the processor in the same order as the requests.

摘要： Restoring retired transaction identifiers (TID) associated with Direct Memory Access (DMA) commands without waiting for all DMA traffic to terminate is disclosed. A scoreboard is used to track retired TIDs and selectively restore retired TIDs on the fly. DMA engines fetch a TID, and use it to tag every DMA request. If the request is completed, the TID can be recycled to be used to tag a subsequent request. However, if a request is not completed, the TID is retired. Retired TIDs can be restored without having to wait for DMA traffic to end. Any retired TID value may be mapped to a bit location inside a scoreboard. All processors in the system may have access to read and clear the scoreboard. Clearing the TID scoreboard may trigger a DMA engine to restore the TID mapped to that location, and the TID may be used again.

摘要： Embodiments of the present invention are directed to systems and methods for controlling the temperature of an internal device while reducing or minimizing the involvement of the host. Thus, some of the heat monitoring and remediation work may be offloaded to the actual device itself. The device may monitor its own temperature and, in the event of high temperature, perform device specific heat reduction actions without involving the host. Furthermore, the device may, upon detecting temperature within a predefined range, alert the host of a high temperature condition in order to allow the host to perform temperature reduction measures. Also, the device may, upon detecting temperature within a predefined range, alert the host of an impending device shutdown and shut the device down. In addition, the device may periodically save its temperature into non-volatile memory in order to create a temperature log.

摘要： A method is disclosed for indicating a status of a transfer of data from a first device to a second device over a network. In one embodiment, the data includes one or more data frames. Each frame includes a header having one or more bits. The method includes setting a last bit of the one or more bits in the header of a last frame of the one or more data frames to a first value if the status of the transfer of data is good and setting the value of the last bit of the last data frame to a second value if the transfer of data failed. This results in a less congested, more efficient network.

摘要： Embodiments of the current invention permit a user to allocate cache memory to main memory more efficiently. The processor or a user allocates the cache memory and associates the cache memory to the main memory location, but suppresses or bypassing reading the main memory data into the cache memory. Some embodiments of the present invention permit the user to specify how many cache lines are allocated at a given time. Further, embodiments of the present invention may initialize the cache memory to a specified pattern. The cache memory may be zeroed or set to some desired pattern, such as all ones. Alternatively, a user may determine the initialization pattern through the processor.
