因为interrupt-map-mask属性是由中断产生设备的地址和中断源(interrupt specifier)组成,且中断源用1个u32表示,那么可以推测中断产生设备地址由3个u32组成。这里需要注意的是pcie@1,0节点的#address-cells属性为3,是说该总线下边的设备地址用3个u32表示,但并不代表中断产生设备的设备地址也一定3个u32表示,此处不能...

To illustrate the point, a portion of the memory map is shown in Table 4.1. A number of interrupts are mapped directly to the local APIC; these must be assigned vectors for each source. The local APIC contains a local vector table (LVT) that associates an interrupt source with a vector ...
Write to the Interrupt Decode Register (0x138) with 1 to the appropriate error bit to clear it. Important:An asserted bit in the Interrupt Decode register does not cause the interrupt line to assert unless the corresponding bit in the Interrupt Mask register is also set. ...
