Determining when to throttle interrupts to limit interrupt processing to an interrupt processing time period

A system for managing interrupts from a hardware device, comprising:

• a processor executing code to perform operations, the operations comprising:
• receiving interrupts from the hardware device;
• determining whether a number of received interrupts exceeds an interrupt threshold during a interrupt tracking time period;
• setting an interrupt throttling state to a first value indicating to only process interrupts during an interrupt processing time period in response to determining that the number of received interrupts exceeds an interrupt threshold;
• processing interrupts from the hardware device during the interrupt time period when the interrupt throttling state is set to the first value;
• and
• masking interrupts received from the hardware during a processing of a scan loop of operations while the interrupt throttling has the first value and the interrupt processing time period has expired, wherein the masked interrupts are not processed while processing the scan loop of operations.
