It takes a while to gradually display the text box. This is because the interrupted operation (entering information into the text box) has a low priority in the interrupt queue, or the CPU considers that the operation being processed (copying files) is too costly, therefore, the current operation will be suspended only when the CPU reaches a

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 controller-the local unit and the I/O unit. In multicore systems, multiple local and I/O APIC cells ca

important role here. Of course, in addition to the preemption, the clock interrupt also takes care of many important functions of the system, such as scheduling queue equalization, Process time update, software timer execution and so on. The following is a brief discussion of the relationship to the clock interrupt from the perspective of preemption, Clock interrupt SourceThe kernel's clock interrupt is implemented based on the device that it is running hardware supports that can peri

I didn't expect the entire Interrupt System to be so complicated in our computer ...... I cannot digest it for a moment. I will chew it later! First, write a little bit: PIC: generally two 8259a Cascade APIC: divided into local APIC (lapic) and I/O APIC (ioapic ). In the system, each (logical) CPU generally has a single lapic. Therefore, if the system has f

cache pools to cache instance objects with those data structures. Memory is consumed in this way. I think 64 MB memory computers are also common if I go back for ten years. If LMOs detects that the memory is less than 64 MB, it will say that the memory is insufficient and then stop the conversion. There are also restrictions on APIC. It must be the APIC on the chip and the

Install KVM in CentOS 7 KVM is short for Kernel Based Virtual Machine. It can use Virtual Hardware extension to provide virtualization software for multiple operating systems. KVM can be managed in two ways, one is command line, the other is a graphical interface. Virt-Manager (Virtual Machine Manager) is the most frequently used management program based on KVM. It can create, edit, start, and pause Virtual machines. Dependency KVM requires the CPU to support hardware virtualization. You can run

fixed so that one of the CPUs can process all interrupt requests; otherwise, the other CPUs cannot interrupt the clock, so if the processes running on those CPUs are in an endless loop, there will never be a chance to make system calls, and these CPUs will never have process scheduling. In addition, if it is to let all the CPUs take turns to process interruptions, or who is idle, how will the allocation of Interrupt requests be handled? These need to be done in collaboration with the software a
