ADJUNCT PROCESSOR COMMAND-TYPE FILTERING

Abstract:

Adjunct processor command-type filtering includes determining whether a target adjunct processor is configured to support a selected command-type filtering mode, and whether another adjunct processor is configured to support the selected command-type filtering mode. Based on determining that the target adjunct processor is not configured to support the selected command-type filtering mode and based on the other adjunct processor being configured to support the selected command-type filtering mode, a command is forwarded to the other adjunct processor for processing to determine whether the command is valid for the selected command-type filtering mode. An indication is obtained, based on processing at the other adjunct processor, of whether the command is valid for the selected command-type filtering mode. Based on obtaining an indication that the command is valid for the selected command-type filtering mode, the command is sent to the target adjunct processor for execution.
