WebAug 19, 2024 · The GIC's internal view of the priority mask register and the assigned interrupt priorities are based on whether GIC security is enabled and whether firmware routes Group 0 interrupts to EL3. At the moment, we support priority masking when ICC_PMR_EL1 and interrupt priorities are either both modified by the GIC, or both left … WebThe ‘interrupt priority mask’ register (ICCPMR) allows interrupt ID’s above the specified value to be disabled. Only the 8 lowest bits in this register are meaningful. Since we are configuring a single interrupt we can leave all other interrupts unmasked.
