Abstract: A command portal enables a host system to send non-standard or “vendor-specific” storage subsystem commands to a storage subsystem using an operating system (OS) device driver that does not support or recognize such non-standard commands. The architecture thereby reduces or eliminates the need to develop custom device drivers that support the storage subsystem's non-standard commands. To execute non-standard commands using the command portal, the host system embeds the non-standard commands in blocks of write data, and writes these data blocks to the storage subsystem using standard write commands supported by standard OS device drivers. The storage subsystem extracts and executes the non-standard commands. The non-standard commands may alternatively be implied by the particular target addresses used. The host system may retrieve execution results of the non-standard commands using standard read commands.

Abstract: In a computer system, a method of controls interrupts which correspond to input/output (I/O) processing. For each delivery of an I/O completion interrupt, the method provides a recordation of a delivery time; identifies I/O completions for which deliveries of corresponding I/O completion interrupts involve deliveries of inter-processor interrupts; and for each of the identified I/O completions, accesses the recordation of the most recent delivery time to determine whether a selected period of time has elapsed since a last delivery of an inter-processor interrupt. As a response to a determination that the selected period has elapsed, an inter-processor interrupt is delivers. As a response to a determination that less than the duration of the selected period has elapsed, the method refrains from delivering an inter-processor interrupt.

Abstract: A serial bit processor is disclosed that configures a timer/counter module to determine a number of data bits to be decoded from a serial bit stream. In some implementations, a serial peripheral is coupled to a timer/counter module.

The serial peripheral then sends count commands that cause the timer/counter to decrement (or increment) by one each time a count command is received. When the count reaches zero, a compare match command is generated and sent to the serial peripheral where it is used to resume or complete the decoding of data bits from the serial bit stream. In some implementations, a serial peripheral is included in a microcontroller that has an event system. The event system is used to communicate commands between peripherals.
