The RING_INT_SRC_RPT_PTR register points to a cacheline in memory to which an engine must report as source of interrupt prior to generating an interrupt to the host. The RING_INT_STATUS_RPT_PTR register points to the first cacheline of the Interrupt Status Report (ISR) page (4KB) in graphics memory to which all engines report their interrupt status. The RING_IMR register has the interrupt enables and interrupt masks for an engine. We will refer to these registers shortly.
