AffinitySymmetric multiprocessor SMP refers to the pooling of a set of processors (multiple CPUs) on a single computer, the sharing of memory subsystems between CPUs and the bus structure, controlled by an operating system. The system distributes the task queue symmetrically over multiple CPUs, which greatly improves the data processing capability of the whole system. All processors have equal access to memory, I/O, and external interrupts. In a symmetric multiprocessor system, the system resou

advanced programmable controller (APIC) to replace the legacy 8259a Programmable Interrupt Controller. First, the new system retains the two cascading vintage PIC 8259a to support older operating systems. Second, the new 80 x CPU control units all contain a local APIC. This is not surprising, in order to support multi-CPU or multi-core systems. Each local APIC h

understanding of the logical block diagram of the HW interrupt system is as follows:There are several CPU blocks in the system to receive interrupt events and processing, several interrupt controllers form a tree-like structure, assemble the IRQ request line for all peripherals in the system, and distribute the interrupt event to a CPU block for processing. From the interface level, there are two main types of interfaces, one is interrupt interface. In some implementations, the specific interru

Today, I changed the "XMPP translation" series to my article. "XMPP translation" is an informative task. Because the translation is generally a chapter, if it is set as an essay, it will occupy a large number of home pages. In addition, there are not many people who need it, publishing an article does not affect sharing. You can go to the article/XMPP translation series or view updates as needed.

both the local interrupt controller of each processor core and the global interrupt controller which is responsible for the interrupt distribution between the various cores. Today's multicore processors primarily use the APIC (Advanced Programmable Interrupt Controllers) for interrupt handling and interrupt control, a high-level programming interrupt controller. It is a distributed architecture based on the two basic functional units of the interrupt

CPU comes with a 64-bit timestamp register, when the clock signal arrives. Automatically add 1 to the Register contents 3): Programmable Interrupt timer (PIC) The device can periodically send a time interrupt signal. The interval at which the interrupt signal is sent can be programmed to control. In a Linux system, the interrupt interval is represented by Hz. This time interval is also called a Beat (tick). 4): CPU Local Timer Additional timing devices are also available on the local

In order to solve this problem, PCI in the process of the evolution of the content of SMI interrupted, PCI devices to the CPU when the interrupt request, directly to the bus to send SMI message, Root complex in the APIC after receiving this message, There are two ways to escalate this interrupt transaction to the processor: the first way is to define a register on the
