ioapic interrupt routing
新版本的Exadata可以检查dmesg|grep “Using IOAPIC for interrupt routing”，来确认APIC timer是否正确开启。 . 例如，下面显示在这个1/4配置 ..., The first interrupt controller chip was the Intel 8259 PIC. It had 8 input lines (IRQ0-7) and 1 output line (which connects the interrupt controller with the INTR line of the CPU). When there is an interrupt from one of the devices on its input lines, th, IOAPIC. The Intel I/O Advanced Programmable Interrupt Controller is used to distribute external interrupts in a more advanced manner than that of the standard 8259 PIC. With the I/O APIC, interrupts can be distributed to physical or logical (clusters of),,Against this, the architecture can be generally seen as an attempt to solve the interrupt routing efficiency issues in MP systems. There is typically one I/O APIC for ... ,It enables us to route hardware interrupts to multiple CPUs, or to CPU groups. Without an IO-APIC, interrupts from hardware will be delivered only to the CPU ... ,An exception to this rule is that some early APIC systems only route ISA IRQs via their sole I/O APIC and still use an programmable interrupt router and a $PIR ... , In my previous post PCI interrupt routing II I studied how PCI interrupt route works.
