Disclosed herein are techniques associated with a Direct Memory Access (DMA) engine that can include a data generation module. The DMA engine can receive, from a processing entity, a particular type of write command with an indicator to write a data pattern to an address. Upon receipt of the particular type of write command, the DMA engine can generate, using a data generation module of the DMA engine, the data pattern to be written to the address. The processing entity can be Central Processing Unit (CPU) including a core configured to process serial commands. The DMA engine can be disposed on a same die as a processing entity or a network interface port.

Pattern generation using a direct memory access engine

Peripheral devices may implement multiple reporting modes for signal interrupts to a host system. Different reporting modes may be determined for interrupts generated at a host system. Reporting modes may be programmatically configured for various operations at the peripheral device. Reporting modes may indicate a reporting technique for transmitting an indication of the interrupt and may indicate a priority assigned to reporting the interrupt. An interrupt controller for the peripheral device may report generated interrupts according to the reporting mode determined for the interrupts.
