    摘要： Certain accesses by a processor to a video graphics controller may cause concurrent accesses by a remote management controller to cause the video graphics controller to lock up. To detect potential lock-up events, the remote management controller snoops the bus to determine whether the processor is performing a type of access that could lead to a potential lock-up condition. If so, the remote management controller ceases accessing the bus until the video graphics controller is in an available state.

    摘要： A memory controller containing one or more ports coupled to a buffer selection logic and a plurality of buffers. Each buffer is configured to store write data associated with a write request and each buffer is also coupled to the buffer selection logic. The buffer selection logic is configured to store write data associated with a write request from at least one of the ports in any of the buffers based on a priority of the buffers for each one of the ports.

    摘要： A system includes proxy logic which detects situations which, unless action is taken, would result in undesirable bus behavior. In one embodiment, the target device of a bus cycle includes proxy logic which determines when the target device is unable to respond correctly to a bus cycle. In this situation, the proxy logic blocks a bus signal from being received by the addressed logic in the target device, thereby preventing the target device from responding at all. In another embodiment, proxy logic is located external to the target device and determines when the target device has not responded to a cycle intended for it. When this condition has occurred, the proxy logic responds to the cycle before the bus's subtractive decode agent has a chance to claim the cycle. The proxy logic's response may be to return bogus data or terminate or abort the cycle.

    摘要： A remote management controller may include a video redirection device and a processor. The video redirection device may be configured to: obtain multiple separate slices of video data output from a video graphics controller; calculate at least one value correlative to each of the multiple separate slices of video data; and if the calculated value for any portion of any of the multiple separate slices differs from a value for a previously obtained corresponding portion, update a table associated with an image related to a remote system with the calculated value, process the portion of the slice into a network packet, and move the network packet to one of multiple network buffers. The processor may be configured to: allocate the multiple network buffers; and facilitate transmission of the network packets loaded into the network buffers to the remote system.

    摘要： A remote management controller may include a capture engine and a processor. The capture engine may be configured to: obtain a slice of video data output from a video graphics controller; calculate at least one value correlative to the slice of video data; determine whether any portion of the slice has been locked; and if any portion has not been locked and if the calculated value for such portion of the slice differs from a value for a previously obtained corresponding portion, move the portion to a virtual screen buffer, update a table associated with the virtual screen buffer with the calculated value, and modify a change table to indicate that the portion has changed. The processor may be configured to: read the change table to determine whether any portion of video data in the virtual screen buffer has changed; and if any portion has changed, lock any changed portion from being accessed by the capture engine, access the changed portion from the virtual screen buffer, and process the changed portion in the virtual screen buffer for transmission to a remote system.
